Japanese Patent Laid-Open No. 2001-241884 (FIG. 1)

However, in the vehicle heat exchange module described in Patent Document 1, hot air from the engine passes under the vehicle heat exchange module and passes through the condenser, particularly when idling (stopped) or at extremely low speed due to traffic jams. It flows into the front side, and this hot air is again taken into the condenser and the radiator by the rotation of the cooling fan and heat exchange is performed (referred to as “recirculation”), so the heat exchange efficiency of these condenser and radiator is reduced. There was a problem.
Since the engine is located close to the downstream side of the cooling fan, the main flow of outside air discharged from the cooling fan collides with the engine wall surface, and the condenser and radiator are increased by the pressure increase on the downstream side of the cooling fan. There is a problem that the amount of air passing through the refrigerant decreases, and the heat exchange efficiency of these capacitors and radiators decreases.

  The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a vehicle heat exchange module and a vehicle capable of improving the heat exchange efficiency of a condenser and a radiator particularly at idling or at an extremely low speed. Yes.

The present invention employs the following means in order to solve the above problems.
The vehicle heat exchange module according to claim 1 is provided with at least one heat exchanger, a cooling fan that forcibly supplies outside air to the heat exchanger, and a substantially circular shape in plan view. A heat exchange module for a vehicle, comprising a fan shroud having an opened opening and guiding outside air heat-exchanged by the heat exchanger through the opening to the cooling fan, the heat exchanger The upstream side of the heat exchanger located on the most upstream side is vertical so that it does not intersect the traveling direction of hot air from the engine that floats in the vicinity of the upstream side through the lower part of the vehicle heat exchange module. It is inclined with respect to the line.
According to such a heat exchange module for a vehicle, especially when idling or at a very low speed, after passing under the heat exchange module for the vehicle, it floats along the upstream side surface of the heat exchanger located on the most upstream side. Since the heat exchanger is arranged so that the hot air from the engine gradually moves away (away from) the upstream side surface of the heat exchanger, it is between the rising hot air and the upstream side surface of the heat exchanger. The relatively cool outdoor air that is located is sucked into the heat exchanger by the cooling fan.

According to a second aspect of the present invention, in the vehicle heat exchange module, an angle formed between the upstream side surface of the heat exchanger located on the most upstream side of the heat exchanger and a horizontal plane is set to 70 ° to 80 °. It is characterized by being.
According to such a heat exchange module for a vehicle, since the angle formed by the upstream side surface of the heat exchanger located on the most upstream side of the heat exchanger and the horizontal plane is set to 80 ° or less, the fan shroud Thus, the so-called recirculation in which the hot air from the engine that has passed around the upstream side of the upstream side surface is taken into the heat exchanger again from the upstream side surface is reduced.
In addition, since the angle between the upstream side surface of the heat exchanger located at the most upstream side and the horizontal plane is set to 70 ° or more among the heat exchangers, a sufficient air volume is provided to the heat exchanger even during traveling. It comes to be supplied.

The vehicle heat exchange module according to claim 3 is provided with at least one heat exchanger, a cooling fan for forcibly supplying outside air to the heat exchanger, and a substantially circular shape in plan view. And a fan shroud for guiding outside air heat-exchanged by the heat exchanger through the opening to the cooling fan, wherein the cooling fan The cooling fan is inclined with respect to the vertical line so that the direction of the main flow of the outside air discharged from is directed downward.
According to such a vehicle heat exchange module, the main flow of the outside air discharged from the cooling fan is affected by the air path resistance caused by the engine arranged close to the downstream side of the cooling fan or the equipment arranged around the engine. Since the pressure is directed in a relatively small direction, the pressure on the downstream side of the cooling fan decreases, and the air volume of the outside air passing through the heat exchanger increases.

The vehicle heat exchange module according to claim 4 is characterized in that an angle formed between a rotating surface formed by the cooling fan and a horizontal plane is set to 75 ° to 85 °.
According to such a heat exchange module for a vehicle, since the angle formed by the rotating surface formed by the cooling fan and the horizontal plane is set to 85 ° or less, the outside air passing through the cooling fan is located downstream of the cooling fan. After passing along the wall surface of the engine disposed in the vicinity of the engine or the device disposed around the vehicle, the vehicle passes through the open space formed between the cooling fan and the engine or the device disposed around the vehicle. The air path resistance decreases, and the air volume passing through the cooling fan, that is, the air volume passing through the heat exchanger increases.
In addition, since the angle between the rotating surface formed by the cooling fan and the horizontal plane is set to 75 ° or more, the loss due to the flow change of the outside air that has passed through the heat exchanger is suppressed, and the outside air is smoothly downstream. Thus, a sufficient air volume is supplied to the heat exchanger.

The vehicle heat exchange module according to claim 5 is provided with at least one heat exchanger disposed near the front of the engine, a cooling fan for forcibly supplying outside air to the heat exchanger, and a substantially circular shape in plan view. And a fan shroud for guiding the outside air heat-exchanged by the heat exchanger through the opening to the cooling fan, the heat exchange module comprising: The upstream side of the heat exchanger located on the most upstream side of the heat exchanger does not intersect the traveling direction of the hot air from the engine that floats in the vicinity of the upstream side through the lower part of the vehicle heat exchange module. The cooling fan is inclined with respect to the vertical line so that the main flow direction of the outside air discharged from the cooling fan is directed downward. And said that you are.

According to such a heat exchange module for a vehicle, especially when idling or at a very low speed, after passing under the heat exchange module for the vehicle, it floats along the upstream side surface of the heat exchanger located on the most upstream side. Since the heat exchanger is arranged so that the hot air from the engine gradually moves away (away from) the upstream side surface of the heat exchanger, it is between the rising hot air and the upstream side surface of the heat exchanger. The relatively cool outdoor air that is located is sucked into the heat exchanger by the cooling fan.
In addition, the main flow of the outside air discharged from the cooling fan is directed in a direction in which the air path resistance by the engine disposed close to the downstream side of the cooling fan or the devices disposed around it is relatively reduced. The amount of air passing through the cooling fan, that is, the amount of outside air passing through the heat exchanger increases.

According to a sixth aspect of the present invention, in the vehicle heat exchange module, an angle formed by an upstream side surface of a heat exchanger located on the most upstream side of the heat exchanger and a horizontal plane is set to 70 ° to 80 °. In addition, the angle formed by the rotating surface formed by the cooling fan and the horizontal plane is set to 75 ° to 85 °.
According to such a heat exchange module for a vehicle, since the angle formed by the upstream side surface of the heat exchanger located on the most upstream side of the heat exchanger and the horizontal plane is set to 80 ° or less, the fan shroud Thus, the so-called recirculation in which the hot air from the engine that has passed around the upstream side of the upstream side surface is taken into the heat exchanger again from the upstream side surface is reduced.
In addition, since the angle between the upstream side surface of the heat exchanger located at the most upstream side and the horizontal plane is set to 70 ° or more among the heat exchangers, a sufficient air volume is provided to the heat exchanger even during traveling. It comes to be supplied.

Further, since the angle formed by the rotating surface formed by the cooling fan and the horizontal plane is set to 85 ° or less, the outside air that has passed through the cooling fan is disposed close to the downstream side of the cooling fan or its engine. After flowing along the wall surface of the equipment placed around, it will be released into the atmosphere from under the vehicle through an open space formed between the cooling fan and the engine or equipment placed around it. Therefore, the air path resistance decreases, and the air volume that passes through the cooling fan, that is, the air volume that passes through the heat exchanger increases.
Furthermore, since the angle formed between the rotating surface formed by the cooling fan and the horizontal plane is set to 75 ° or more, the loss due to the flow change of the outside air that has passed through the heat exchanger is suppressed, and the outside air is smoothly downstream. It will be sent out to the side, and sufficient air volume will be supplied to a heat exchanger.

The vehicle heat exchange module according to claim 7 is provided with at least one heat exchanger, a cooling fan for forcibly supplying outside air to the heat exchanger, and a substantially circular shape in plan view. A vehicle heat exchange module, comprising: a fan shroud having an opened opening, and a fan shroud that guides outside air heat-exchanged by the heat exchanger to the cooling fan through the opening. An opening is provided on a lower surface located between the cooling fan and a heat exchanger provided adjacent to the upstream side of the cooling fan.
According to such a vehicle heat exchange module, particularly when idling or at extremely low speeds, hot air from the engine staying under the fan shroud is sucked into the cooling fan through the opening by the rotation of the cooling fan. It has come to go.
That is, when idling or at extremely low speeds, the hot air that attempts to flow around the upstream side of the heat exchanger through the lower part of the fan shroud is collected toward the cooling fan through the opening. Therefore, recirculation is suppressed, and outside air having a relatively low temperature is supplied to the heat exchanger.

The vehicle heat exchange module according to claim 8 is characterized in that the plate member that opens and closes the opening is rotatably attached via a hinge portion disposed on the front side of the vehicle.
According to such a heat exchange module for a vehicle, the opening is opened at idling or extremely low speed, and the opening is closed when the vehicle speed wind exceeds a predetermined speed.
That is, at idling or extremely low speed when the vehicle speed wind that hits the plate member is almost zero, the plate member rotates about the hinge portion by its own weight to open the opening, and passes through the lower part of the fan shroud and the heat exchanger Hot air that tends to circulate to the upstream side surface is collected by the cooling fan through the opening.
On the other hand, when the vehicle starts traveling (to the forward side) and the vehicle speed wind hitting the plate member exceeds a predetermined speed, the plate member rotates about the hinge in the opposite direction to the open state, and the opening is closed. Therefore, inflow of outside air from the opening to the inside of the fan shroud and outflow of outside air from the opening to the outside of the shroud are prevented, and rotation of the cooling fan causes a sufficient amount of outside air to flow into the heat exchanger. It comes to be supplied.

The vehicle heat exchange module according to claim 9 is provided with at least one heat exchanger disposed in the vicinity of the engine, a cooling fan for forcibly supplying outside air to the heat exchanger, and a substantially circular shape in plan view. A heat exchange module for a vehicle, comprising a fan shroud having an opened opening and guiding outside air heat-exchanged by the heat exchanger through the opening to the cooling fan, the heat exchanger The hot air from the engine, which has risen along the upstream side surface of the heat exchanger located on the most upstream side, passes above the heat exchanger and is provided adjacent to the cooling fan and the upstream side of the cooling fan. A duct that leads to the heat exchanger and a recovery portion that extends further upstream from the upstream upper end surface of the duct and hangs down toward the upstream side surface. To.
According to such a vehicle heat exchange module, especially when idling or at a very low speed, it passes under the fan shroud and wraps around the upstream side of the heat exchanger located most upstream among the heat exchangers, Since hot air from the engine that floats in the vicinity of the upstream side surface of the heat exchanger is guided to the duct along the inner wall surface of the recovery unit, it is recovered by a cooling fan that rotates through the duct. Outside air having a relatively low temperature is supplied to the heat exchanger.
That is, when idling or at extremely low speeds, the hot air that has passed through the lower part of the fan shroud to the upstream side of the heat exchanger is recovered toward the cooling fan through the recovery part and duct. Thus, it is difficult for hot air to stay on the upstream side surface of the heat exchanger, and outside air having a relatively low temperature reaches the upstream side surface of the heat exchanger.

The vehicle heat exchange module according to claim 10, wherein a tip of the recovery unit is positioned in the same horizontal plane as an upper end of a heat exchange surface of a heat exchanger located on the most upstream side of the heat exchanger. It is provided.
According to such a vehicle heat exchange module, the tip of the recovery unit is provided so as to be located in the same horizontal plane as the upper end of the heat exchange surface of the heat exchanger located on the most upstream side of the heat exchanger. Therefore, when the vehicle starts running (toward the forward side), the entrance of the duct is closed by the recovery unit, the flow of outside air from the duct to the cooling fan is cut off, and it passes through the heat exchanger Only the outside air is guided to the cooling fan, and a sufficient air volume is ensured even during traveling.

A vehicle according to an eleventh aspect includes the vehicle heat exchange module according to any one of the first to tenth aspects.
According to such a vehicle, particularly when idling or at extremely low speeds, the hot air from the engine that passes under the fan shroud and wraps around the upstream side of the heat exchanger is reduced, and the upstream side of the heat exchanger has a relatively high temperature. Low outside air will arrive, and the heat exchange efficiency of the heat exchanger will be improved.
Also, since the direction of the main flow of the outside air discharged from the cooling fan is directed downward (toward the ground), the air path resistance is reduced and the amount of air passing through the cooling fan, that is, passing through the heat exchanger The air volume of the outside air to be increased will increase the heat exchange efficiency of the heat exchanger.

According to the vehicle heat exchange module of the present invention, the hot air from the engine staying in the vicinity of the upstream side surface of the heat exchanger located on the most upstream side is reduced, and the outside air having a relatively low temperature is supplied to the heat exchanger. As a result, the heat exchange efficiency of the heat exchanger can be improved.
In addition, since the outside air passing through the cooling fan is discharged to the side with less airflow resistance, the amount of outside air passing through the heat exchanger can be increased, and the heat exchange efficiency of the heat exchanger is improved. Can be made.
According to the vehicle including the vehicle heat exchange module according to the present invention, since the vehicle heat exchange module excellent in heat exchange efficiency is mounted, the room can be quickly brought to a desired temperature condition.

Hereinafter, a first embodiment of a vehicle heat exchange module according to the present invention will be described with reference to the drawings.
As shown in FIG. 6, the vehicle heat exchange module 10 is provided in an engine room E disposed in the front portion of the vehicle 100 together with the engine 11 and the like.
Further, as shown in FIG. 7 when the rear surface side of the vehicle heat exchange module 10 is viewed from the engine room E, the vehicle heat exchange module 10 is provided close to the rear surface side of the bumper 12, and is not shown in the front. The outside air that has passed through the grill is guided to the front side of the vehicle heat exchange module 10.

FIG. 1 is a schematic longitudinal sectional view of the vehicle heat exchange module (also referred to as “Condenser Radiator Fan Module (CRFM)”) 10 shown in FIGS. 6 and 7.
As shown in FIG. 1, the vehicle heat exchange module 10 includes a condenser (heat exchanger) 13, a radiator (heat exchanger) 14, a fan shroud 15, and a cooling fan 16 as main elements. The condenser 13, the radiator 14, and the cooling fan 16 are arranged in this order from the upstream side (left side in the figure).
Each of the condenser 13 and the radiator 14 is a heat exchanger having a rectangular shape in plan view (the same shape as the plan view shape of the fan shroud 15 shown in FIG. 7).
The condenser 13 is a component of the vehicle air conditioner, and is configured to cool and liquefy the high-temperature and high-pressure refrigerant gas compressed by the compressor by heat exchange with the outside air passing through the condenser 13. Is.
The radiator 14 is configured to lower the temperature of the engine cooling water by exchanging heat with the outside air passing through the radiator 14.
The cooling fan 16 is for forcibly supplying outside air to the radiator 14.
Since the capacitor 13, the radiator 14, and the cooling fan 16 are each well known in the art, detailed description thereof is omitted here.

The fan shroud 15 is configured to guide all outside air that has passed through the condenser 13 and the radiator 14 to the cooling fan 16. The fan shroud 15 connects the outer peripheral wall 17, the bell mouth 18, and the outer peripheral wall 17 and the bell mouth 18. The bottom plate 19 to be connected is a main element.
The outer peripheral wall 17 is connected to the radiator 14 so that the air that has passed through the radiator 14 is guided to the cooling fan 16, and the condenser 13 is further connected upstream of the radiator. The bell mouth 18 extends from the inner peripheral edge of the bottom plate 19 toward the downstream side (the side opposite to the capacitor 13 and the radiator 14).

As shown in FIG. 7, the radiator 14 is connected to the upstream side of the bottom plate 19, and the capacitor 13 is further connected to the upstream side of the radiator.
An opening 20 opened in a circular shape in plan view is provided in the center of the bottom plate 19, and the bell mouth 18 described above extends from the opening 20 toward the downstream side. The outside air that has passed through the condenser 13 and the radiator 14 is led to the downstream side through the opening 20.
Therefore, outside air that has passed through the condenser 13 and the radiator 14 is guided to the outer peripheral wall 17 and the bottom plate 19 of the fan shroud 15 and reaches the opening 20, and is discharged downstream by the cooling fan 16.

As shown in FIG. 1, in this embodiment, the upstream side surface 13a of the capacitor 13 is configured to be inclined with respect to the vertical line. That is, the upstream side surface 13a of the capacitor 13 is inclined so that the upper end of the capacitor 13 is located behind the lower end. In other words, the angle αc formed by the upstream side surface 13a of the capacitor 13 and the horizontal plane L is set to be 70 ° to 80 °.
On the other hand, the radiator 14 and the cooling fan 16 are set so that the upstream side surface 14a and the rotating surface 16a are parallel to the vertical line, that is, the angle formed with the horizontal plane L is 90 °.

By inclining the upstream side surface 13a of the condenser 13 in this way, the hot air from the engine 11 that has flowed under the fan shroud 15 to the upstream side of the condenser 13 at an extremely low speed due to idling or traffic jams is When the vicinity of the upstream side surface 13a is levitated, it gradually moves away from the upstream side surface 13a. That is, since the relatively low temperature outside air located between the hot air floating in the vicinity of the upstream side surface 13a and the upstream side surface 13a flows into the capacitor 13 and the radiator 14 from the upstream side surface 13a, The heat exchange efficiency of the radiator 14 can be improved.
Further, since the angle αc formed by the upstream side surface 13a and the horizontal plane L is set to 80 ° or less, the hot air from the engine 11 that has passed through the lower side of the fan shroud 15 and has flowed to the upstream side of the condenser 13 is upstream side surface 13a. Therefore, the so-called recirculation that is re-introduced into the condenser 13 and the radiator 14 can be reduced to less than half of the conventional (αc = 90 °), and the heat exchange efficiency of the condenser 13 and the radiator 14 can be improved.
Further, since the angle αc formed by the upstream side surface 13a and the horizontal plane L is set to 70 ° or more, a sufficient air volume can be ensured even during traveling, and the heat exchange efficiency of the condenser 13 and the radiator 14 is sufficient. Can be secured.

2nd Embodiment of the heat exchange module for vehicles by this invention is described referring drawings.
The vehicle heat exchange module 30 in the present embodiment is different from that in the first embodiment described above in that the cooling fan 16 is inclined instead of the capacitor 13 in the first embodiment described above.
In addition, the same code | symbol is attached | subjected to the member same as 1st Embodiment.

As shown in FIG. 2, in this embodiment, the rotation surface 36a of the cooling fan 36 is configured to be inclined with respect to the vertical line. That is, the rotation surface 36a of the cooling fan 36 is inclined so that the upper end of the rotation surface 36a of the cooling fan 36 is located behind the lower end of the rotation surface 36a. In other words, the angle αf formed between the rotating surface 36a of the cooling fan 36 and the horizontal plane L is set to be 75 ° to 85 °.
On the other hand, the condenser 33 and the radiator 14 are set so that the upstream side surfaces 33a and 14a are parallel to the vertical line, that is, the angle formed with the horizontal plane L is 90 °.

By inclining the cooling fan 36 so that the angle αf formed by the rotation surface 36 a and the horizontal plane L is 85 ° or less, the outside air that has passed through the cooling fan 36 is disposed close to the downstream side of the cooling fan 36. After flowing along the wall surface of the engine 11 or the equipment disposed around the engine 11, it passes from the bottom of the vehicle through an open space formed between the cooling fan 36 and the engine 11 or the equipment disposed around the engine 11. Since it is released into the atmosphere, the air path resistance can be reduced, and the amount of air passing through the cooling fan, that is, the amount of outside air passing through the condenser 33 and the radiator 14 can be increased. And the heat exchange efficiency of the radiator 14 can be improved.
In addition, since the angle formed by the rotating surface 36a formed by the cooling fan 36 and the horizontal plane L is 70 ° or more, loss due to a change in the flow path of the outside air that has passed through the heat exchanger can be suppressed. Can be smoothly sent to the downstream side, and the heat exchange efficiency of the condenser 33 and the radiator 14 can be sufficiently ensured.

A third embodiment of a vehicle heat exchange module according to the present invention will be described with reference to the drawings.
The vehicle heat exchange module 40 in the present embodiment is a combination of the first embodiment and the second embodiment described above.
In addition, the same code | symbol is attached | subjected to the member same as 1st Embodiment and 2nd Embodiment.

As shown in FIG. 3, in this embodiment, the effects of both the first embodiment and the second embodiment can be obtained at the same time, so that the heat exchange efficiency of the condenser 13 and the radiator 14 can be further improved.
Since the detailed operational effects have been described in the first embodiment and the second embodiment, detailed description thereof will be omitted here.

A vehicle heat exchange module according to a fourth embodiment of the present invention will be described with reference to the drawings.
The vehicle heat exchange module 50 according to the present embodiment has hot air recovery means 51 on the lower surface of the fan shroud 15.
In addition, the same code | symbol is attached | subjected to the member same as embodiment mentioned above.

As shown in FIG. 4, the hot air recovery means 51 is constituted mainly by an opening 52 formed on the lower surface of the fan shroud 15 and a plate member 53 that opens and closes the opening 52.
The opening 52 is a through hole having a rectangular shape in plan view (viewed from below in the drawing) provided in the extending direction of the condenser 13 and the radiator 14, that is, along the upstream side surfaces 33a and 14a. When rotated, outside air (hot air from the engine 11 when idling or the like) is sucked into the inside from the outside (lower side in the figure) of the fan shroud 15.

The plate member 53 is a thin plate-like member having one end attached to the lower surface of the fan shroud 15 via the hinge portion 54 so that the opening portion 52 can be opened or closed by rotating around the hinge portion 54. It is configured.
The plate member 53 rotates around the hinge portion 54 by its own weight (clockwise in the drawing) due to its own weight at an extremely low speed such as when idling or in a traffic jam, and opens the opening 52 as indicated by a solid line in FIG. On the other hand, when the vehicle speed becomes equal to or higher than the predetermined speed, the vehicle speed wind W indicated by a white arrow in the drawing rotates around the hinge portion 54 (counterclockwise in the drawing), and the opening 52 is shown by a two-dotted line in FIG. Close as shown.

As described above, when the opening 52 is opened at an extremely low speed such as when idling or in a traffic jam, the hot air from the engine 11 passing through the lower side of the fan shroud 15 to the upstream side of the condenser 33 is changed to the plate member. 53 is raised toward the opening 52 along the surface (the right side surface in the figure) and is collected by the cooling fan 16 rotating through the opening 52, so It is possible to prevent the hot air from the engine 11 from flowing in, and the outside air having a relatively low temperature flows into the condenser 33 and the radiator 14 from the upstream side surface 33a, and the heat exchange efficiency of the condenser 33 and the radiator 14 is improved. be able to.
Further, the opening 52 is closed during traveling when the vehicle speed is equal to or higher than a predetermined speed, whereby the flow of outside air from the opening 52 to the cooling fan 16 is blocked and the outside air from the opening 52 to the outside of the fan shroud 15 is blocked. Therefore, a sufficient air volume can be supplied to the condenser 33 and the radiator 14 even during traveling, and the heat exchange efficiency of the condenser 33 and the radiator 14 can be sufficiently ensured.

5th Embodiment of the heat exchange module for vehicles by this invention is described referring drawings.
The vehicle heat exchange module 60 according to the present embodiment has a hot air recovery means 61 at the top of the fan shroud 15.
In addition, the same code | symbol is attached | subjected to the member same as embodiment mentioned above.

As shown in FIG. 5, the hot air recovery means 61 includes a duct 62 provided in the upper part of the fan shroud 15, and extends further upstream from the upstream upper end surface of the duct 62 and toward the upstream side surface 33 a of the capacitor 33. The collection part 63 that hangs down is configured as a main element.
The duct 62 does not pass through the condenser 33 and the radiator 14, but guides outside air existing in the vicinity of the upstream side surface 33 a of the condenser 33 between the cooling fan 16 and the radiator 14 through above the condenser 33 and the radiator 14. These pipes (or conduits) are provided along the extending direction of the capacitor 33 and the radiator 14, that is, along the upstream side surfaces 33a and 14a.
As a result, when the cooling fan 16 rotates, outside air existing above the upstream side surface 33a of the condenser 33 (hot air from the engine 11 during idling or the like) is sucked.

The recovery part 63 is a member like a ridge extending upstream from the upstream upper end surface of the duct 62, and passes around the fan shroud 15 to the upstream side of the capacitor 33 at the time of idling or the like. This is for guiding more hot air from the engine 11 floating near the side surface 33a toward the cooling fan 16.
Further, the tip 63 a of the recovery unit 63 is provided so as to be located in the same horizontal plane as the heat exchange surface upper end 33 b of the condenser 33.

In this way, at the time of idling or extremely low speed such as traffic congestion, the air from the engine 11 that flows under the fan shroud 15 to the upstream side of the capacitor 33 and floats in the vicinity of the upstream side surface 33a of the capacitor 33 is recovered by the recovery unit. After being guided to the duct 62 along the inner wall surface 63 (the lower surface in the figure), it is recovered by the cooling fan 16 rotating through the duct 62, so that the outside air having a relatively low temperature is upstream. It can be made to flow into the condenser 33 and the radiator 14 from the side surface 33a, and the heat exchange efficiency of the condenser 33 and the radiator 14 can be improved.
Further, since the tip 63a of the recovery unit 63 is provided so as to be located in the same horizontal plane as the heat exchange surface upper end 33b of the condenser 33, when the vehicle starts traveling (to the forward side), the recovery unit 63 The entrance of the duct 62 is closed, the flow of outside air from the duct 62 to the cooling fan 16 is blocked, and the outside air existing in front of the heat exchange surface of the condenser 33 passes only the condenser 33 and the radiator 14. Thus, a sufficient air volume can be ensured even during traveling, and the heat exchange efficiency of the condenser 33 and the radiator 14 can be sufficiently ensured.

In addition, this invention is not limited to the thing of embodiment mentioned above, For example, any one embodiment in 1st Embodiment to 3rd Embodiment and 4th Embodiment may be combined. In addition, any one of the first to third embodiments may be combined with the fifth embodiment.
