  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
In FIG. 1, reference numeral 1 denotes a building, and a mobile phone base station 3 is provided on the rooftop 2 thereof.

  The base station 3 is composed of a box-shaped cabinet 4, a transmitter / receiver 5 provided in the cabinet 4, and a heat exchange device 6 provided at the front opening of the cabinet 4 so as to be opened and closed like a door. Yes.

  As shown in FIGS. 2 to 4, the heat exchanging device 6 includes a first intake port 7 and a first discharge port 8 for outside air (first environment), and a second for the inside of the cabinet 4 (second environment). A main body case 11 having an intake port 9 and a second discharge port 10, a first blower fan 12 for outside air (first environment) and an interior of the cabinet 4 (second environment) provided in the main body case 11. A second blower fan 13 and a heat exchanger 14 for exchanging heat between the air in the outside air (first environment) and the air in the cabinet 4 (second environment) in the main body case 11 are provided.

  As shown in FIGS. 5 and 6, the heat exchanger 14 has a rectangular synthetic resin-made second plate body 16, a second synthetic resin-made second plate body 16 on the surface of a rectangular synthetic resin-made first plate body 15. A third plate 17 made of a synthetic resin (hereinafter, a plurality of plates are stacked in the same manner) is polymerized on the surface of the plate 16 as shown in FIG. It is made the composition made to do.

  The upper surface in FIG. 6 of the heat exchanger 14 thus superposed is an inlet 18 through which the air in the cabinet 4 flows in via the second air inlet 9, and heat exchange from this inlet 18 The air that has flowed into the vessel 14 is then discharged into the cabinet 4 from an outlet 19 provided on the lower right side of FIG. 6 and used for cooling the transmitter / receiver 5.

  Further, the outside air outside the cabinet 4 flows in from the inlet 20 provided on the lower surface in FIG. 6 and flows out of the cabinet 4 from the outlet 21 provided on the upper left side, that is, outside air.

  Such ventilation will be described in more detail later, but heat exchange between the outside air and the air in the cabinet 4 is performed by the heat exchanger 14, thereby cooling the transmitter / receiver 5 using the outside air. become.

  That is, a current of several tens of amperes or more flows in the transmitter / receiver 5, and the temperature rises accordingly. If such a high temperature of the transmitter / receiver 5 is left unattended, its characteristics become unstable. In this embodiment, as described above, the heat in the cabinet 4 is cooled by heat exchange with the outside air by the heat exchanger 14. As a result, the transmitter / receiver 5 is prevented from becoming unstable.

  The heat exchanger 14 as described above has a rectangular synthetic resin-made second plate 16 and a second synthetic resin on the surface of the rectangular-shaped synthetic resin-made first plate 15 shown in FIG. A third plate 17 made of synthetic resin is polymerized in order on the surface of the plate 16.

  More specifically, on the surface of the first plate 15 on the second plate 16 side, a plurality of first rectifying walls 22 that partition the surface of the first plate 15 in a lane shape, and the second plate The surface of the second plate body 16 on the third plate body 17 side is provided with a plurality of second rectifying walls 23 that partition the surface of the second plate body 16 in a lane shape, and further on the surface of the third plate body 17. The third straightening walls 24 projecting to the opposite side of the second plate 16 are provided.

  Further, as shown in FIG. 7, a part of the first rectifying wall 22 of the first plate 15 is formed on the lower surface side by the formation of the second rectifying wall 23 of the second plate 16. A first protrusion 26 that enters the first plate body side recess 25 is provided, and a third rectification of the third plate body 17 is provided on a part of the second rectification wall 23 of the second plate body 16. A second protrusion 27 is provided to enter the second plate-side recess 25a on the lower surface side by forming the wall 24.

  These first to third plate bodies 15, 16, 17 have a rectangular shape in the vertical direction as understood from FIGS. 5 and 6, and the first plate body 15 has a lower end (one end). ) From the upper end (the other end) side, the first straightening wall 22 is linearly extended. Further, the first rectifying wall 22 is shaped to be bent toward the left long side (first long side) in FIG. 5 before the upper end side, and the left long side portion becomes the outlet 21. ing.

  Next, the second plate body 16 linearly extends the second rectifying wall 23 from the upper end (the other end) to the lower end (the one end), and the length of the right side in FIG. The shape is curved to the side (second long side) side, and the long side portion on the right side is the outlet 19. (Here, further explanation is simplified, but thereafter the first plate 15 and the second plate 16 are alternately polymerized in the same manner. However, in this embodiment, claims are made. In order to maintain consistency with the range, the third plate body 17 is described, but the third plate body 17 and the first plate body 15 are the same. The fourth plate to be polymerized by the body 17 is the same as the second plate 16).

  Further, as shown in FIG. 5, the curved portion 28 toward the first long side of the first plate 15 and the curved portion toward the second long side of the second plate 16. 29 increases the distance between the first and second rectifying walls 22 and 23 to prevent the ventilation resistance from increasing even a little.

  That is, if the first and second rectifying walls 22 and 23 are formed at the same density as the long side on the curved portions 28 and 29 of the first plate body 15 or the second plate body 16, the ventilation path is formed. Bending resistance increases due to bending.

  Therefore, in order to avoid this, in the curved portion 28, the interval (distance) between the adjacent first rectifying walls 22 is made larger than the straight portion of the first rectifying wall 22.

  In the curved portion 29, the interval (distance) between the adjacent second rectifying walls 23 is made larger than that of the straight portion of the second rectifying wall 23.

  Further, when attention is paid to the bending portion 29 of the second plate body 16, the first plate body 15 and the third plate body 17 adjacent to the bending portion 29 are arranged in a first direction orthogonal to the bending portion 29. Since the third rectifying walls 22 and 24 are formed, even if the interval (distance) between the adjacent second rectifying walls 23 is large in the curved portion 29, the adjacent wall surfaces (first plate) are caused by thermal expansion. The entry of the body 15 and the third plate body 17) does not occur.

  However, as a precaution, in this embodiment, the first plate 15 of the curved portion 28 portion has a curved surface substantially orthogonal to the straight portion of the second rectifying wall 23, and the curved portion 29 portion. The second plate body 16 is formed with a curved surface substantially orthogonal to the straight portions of the first and third rectifying walls 22 and 24. Although these curved surfaces are not shown in order to avoid complication of the drawing, the first plate body 15 itself of the curved portion 28 and the second plate body 16 of the curved portion 29 are referred to as “slowly. It is made to be in a state of being curved in a “smooth protruding arc shape (kamaboko shape)”.

  Now, according to the configuration as described above, the air heated by the transmitter / receiver 5 in the cabinet 4 flows from the second air inlet 9 of the heat exchanger 6 to the second blower fan 13 as shown in FIG. 5 and 6 flows into the heat exchanger 14 through the inlet 18 in FIGS. 5 and 6, passes between the second plate 16 and the third plate 17, and becomes cool air from the outlet 19. 4, thereby cooling the transmitter / receiver 5.

  On the other hand, outside air is sucked into the first blower fan 12 from the first air inlet 7 of FIG. 2 and flows into the heat exchanger 14 from the inlet 20 of FIGS. It passes between the second plate bodies 16 and flows out of the cabinet 4 through the outlet 21 and the first outlet 8, that is, to the outside air.

  Here, the outside air passing between the first and second plate bodies 15 and 16 as described above, and the air inside the cabinet 4 passing between the second and third plate bodies 16 and 17 are respectively the first and first plates. The first and second rectifying walls 22 and 23 provided on the two plate bodies 15 and 16 are uniformly distributed over the entire surface of the plate body, so that heat exchange between the outside air and the air in the cabinet 4 can be performed over a wide area. Done.

  Now, when heat exchange is performed in this way, when the outside air temperature is very high, the temperature in the cabinet 4 also becomes very high, and as a result, the first, second, and third plate bodies 15. , 16, 17 are thermally expanded, and the portion between the first rectifying walls 22 or the portion between the second rectifying walls 23 is adjacent to the plate (for example, the first, second, third plate 15, 16, 17), and the passage may be narrowed or blocked.

  Therefore, in the present embodiment, as described above and as shown in FIG. 7, the second plate 16 has the second plate 16 on the part of the first rectifying wall 22 of the first plate 15. The first protrusion 26 is provided so as to protrude into the first plate body side concave portion 25 on the lower surface side by forming the rectifying wall 23 and to come into contact with the inner top surface of the first plate body side concave portion 25.

  Further, a part of the second rectifying wall 23 of the second plate body 16 enters a second plate body side recess 25a on the lower surface side by the formation of the third rectifying wall 24 of the third plate body 17. The second protrusion 27 is provided in contact with the inner top surface of the second plate-side recess 25a.

  For this reason, even if the high temperature state as described above occurs and the first, second, and third plate bodies 15, 16, and 17 thermally expand, the first protrusions 26 of the first plate body 15 The upper side second plate body 16 is in contact with and supported by the first plate body side recess 25, and the second projection 27 of the second plate body 16 is supported by the third plate body 17 on the upper side. Since the second plate body side concave portion 25a is in contact with and supported by the second plate body side concave portion 25a, the portion between the first rectifying walls 22 or the portion between the second rectifying walls 23 is adjacent to the plate body (for example, the first, second, third The plate 15, 16, 17) is rushed into the plate body, whereby the passage is not narrowed or blocked, so that a state of high heat exchange efficiency can be maintained.

  FIGS. 8 to 10 show another embodiment of the present invention. In this embodiment, a shortcut in the curved portion of the first to third rectifying walls 22, 23, 24 shown by the arrow in FIG. 8 is prevented. Is.

  That is, for example, as can be understood from FIG. 10, the second rectifying wall 23 of the second plate 16 is in an orthogonal state in the curved portion of the first rectifying wall 22 of the first plate 15. At this time, the first plate-side concave portion 25 is formed by forming the second rectifying wall 23, and a shortcut in the curved portion occurs by passing through the first plate-side concave portion 25.

  That is, an air flow that shortcuts the inlet 18 and the outlet 19 of the heat exchanger 14 shown in FIG. 6 is generated, and an air flow that shortcuts the inlet 20 and the outlet 21 is generated.

  Therefore, in this embodiment, as shown in FIGS. 9 and 10, the second rectifying wall of the second plate body 16 adjacent to the curved portion of the first rectifying wall 22 of the first plate body 15 is provided. 23 is provided with a first sealing protrusion 30 that enters the first plate body side recess 25 by the formation of the second rectifying wall 23 of the second plate body 16 at a portion orthogonal to the straight portion, and the second plate A portion of the third plate 17 that is perpendicular to the curved portion of the third rectifying wall 24 of the third plate 17 adjacent to the straight portion of the second rectifying wall 23 of the body 16 is provided. A second sealing protrusion 30a that plunges into the second plate body-side recess 25a due to the formation of the rectifying wall 24 is provided.

  As shown in FIG. 10, the first sealing protrusion 30 has a shape with a small diameter on the second plate 16 side, and the second sealing protrusion 30a has a shape with a small diameter on the third plate 17 side. The first plate body-side concave portion 25 formed by forming the second rectifying wall 23 of the second plate body 16 has a shape with a large diameter on the first plate body 15 side, and the third rectification of the third plate body 17 is performed. The second plate body side concave portion 25a formed by the wall 24 has a shape with a large diameter on the second plate body 16 side.

  Therefore, as understood from FIG. 10, the curved portion of the first rectifying wall 22 of the first plate 15 and the straight portion of the second rectifying wall 23 of the second plate 16 adjacent thereto. The first sealing projection 30 enters the first plate-side recess 25 formed by the formation of the second rectifying wall 23 of the second plate 16 that has been formed in a portion orthogonal to the second plate 16, so-called A lid is formed.

  Similarly, the second plate-side recess 25a formed in the curved portion of the third rectifying wall 24 of the third plate 17 is also in a state of being covered with the second sealing protrusion 30a. .

  For this reason, the shortcut in the curved part of the 1st-3rd rectification | straightening wall 22,23,24 shown by the arrow of the said FIG. 8 can be prevented, and the fall of the heat exchange efficiency of the heat exchanger 14 is prevented as a result. be able to.

The gap between the wall 22 and the second plate 16 and between the second rectifying wall 23 and the third plate 17 is eliminated to prevent a shortcut.

  In the present invention, the first rectifying wall 22 is a portion where the linear portion of the first rectifying wall 22 of the first plate 15 and the first plate-side concave portion 25 of the second plate 16 overlap in the vertical direction. A gap is formed between the first plate body side concave portion 25 and a shortcut is easily generated. However, by making the first protrusion 26 as large as possible, the first rectifying wall 22 and the first plate body side concave portion are formed. The gap between 25 can be closed, a shortcut can be prevented, and the heat exchange efficiency of the heat exchanger 14 can be improved.

  Although not shown, the first rectifying wall 22 has a first plate-side recess 25 in a portion where the straight portion of the first rectifying wall 22 and the straight portion of the second rectifying wall 23 overlap in the vertical direction. The second rectifying wall 23 enters the inside of the second plate-side recess 25a. This eliminates the gap between the first rectifying wall 22 and the second plate body 16 and between the second rectifying wall 23 and the third plate body 17, thereby preventing a short-cut and the heat of the heat exchanger 14. Exchange efficiency can be improved.
