2. Description of the Related Art A vehicle is provided with a cooling device for maintaining the cooling water for the engine at an appropriate temperature and an air conditioner for maintaining the interior of the vehicle at a comfortable temperature. In the cooling device, the high-temperature cooling water heated by the engine is guided to a radiator, and the high-temperature cooling water is cooled by the radiator, and the cooled cooling water is again guided to the engine. In an air conditioner, a compressor (compressor) is driven by driving an engine, and the gas that has been compressed by the compressor and has become hot is cooled and liquefied by a condenser (condenser).
Then, the liquefied gas is sent from a receiver tank (liquid receiver) to an evaporator (evaporator) through a sight glass and an expansion valve (expansion valve), and the heat in the vehicle cabin when the gas is vaporized by the evaporator. Some rob it, cool it, and then send that gas back to the compressor.

In mounting a radiator of a cooling device and a condenser of an air conditioner on a vehicle, as shown in FIGS. 5 and 6, a radiator 102 is supported by a body member (not shown) at the front of the vehicle. And the radiator 102
, A condenser 104 is provided in parallel in front of the vehicle.

The radiator 102 includes a radiator core 106 made of aluminum, a radiator upper tank 110 made of resin provided above the radiator core 106 via an upper caulking portion 108, and a lower caulking below the radiator core 106. A radiator lower tank 114 made of resin provided via a portion 112. The radiator upper tank 110 is provided with radiator upper mounting bosses 116 on the front side of the vehicle. The radiator lower tank 114 is provided with radiator lower mounting brackets 118 on the front side of the vehicle.

The capacitor 104 is entirely made of aluminum (full wrap). Capacitor upper mounting brackets 122, 122 corresponding to the upper mounting bosses 116, 116 are provided on the upper portion of the capacitor core 120, and the radiator is provided on the lower portion. Capacitor lower mounting brackets 124, 124 corresponding to lower mounting brackets 118, 118
Is provided.

The upper side of the capacitor 104 has upper bolts 128, 1 inserted into upper bolt holes 126, 126 of the upper brackets 122, 122.
The radiator lower tank 110 is attached to the radiator upper tank 110 at 28 and the lower side is the radiator lower mounting bracket 11.
8 and 118 are inserted through the insertion holes 130 and 130 from above, and are elastically supported on the radiator lower mounting brackets 118 and 118 via the rubber mounts 132 and 132.

[0007] Such a mounting structure of a radiator and a capacitor is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-85347.
JP-A-11-287590, JP-A-11-515
87 and JP-A-10-148123. Japanese Unexamined Patent Application Publication No. 8-85347 discloses a radiator upper tank made of resin, and a capacitor attached to the radiator upper tank by mounting bolts as pillars. Japanese Patent Laying-Open No. 11-287590 discloses a radiator and a capacitor which are integrally formed to reduce the number of components. Japanese Unexamined Patent Application Publication No. 11-51587 discloses a radiator in which a radiator core is provided with a reinforcement and a capacitor is provided with a bracket connected to the reinforcement. JP-A-10-14

[0008]

By the way, in the conventional mounting structure of a radiator and a capacitor, when a capacitor is mounted on a radiator, an aluminum capacitor is mounted on a radiator by a mounting bolt. When mounted directly on the radiator core made of aluminum and the radiator upper tank and radiator lower tank made of resin have different coefficients of thermal expansion, the heat of the aluminum radiator core is It is shut off by the radiator lower tank, the expansion of the condenser cannot follow the expansion of the radiator, causing damage to the mounting bracket.Therefore, use a rubber mount on the lower side as one side, Radiator core heat When to absorb Zhang, parts, assembling steps, the cost is increased and also there is a disadvantage that the weight is increased

In addition, the smaller the gap between the radiator and the condenser, which are arranged in parallel and opposed to each other, the smaller the air that escapes from the gap, so that the cooling performance of the cooling device and the efficiency of the air conditioning performance of the air conditioner are better. However, in the radiator, the upper side between the radiator core and the radiator upper tank / radiator lower tank,
Since there is a lower caulking part and the width of the upper and lower caulking parts is large, in the case of all aluminum capacitors,
The gap between the radiator and the condenser (indicated by S3 in FIG. 6) becomes large, and the efficiency of the cooling performance and the air-conditioning performance decreases, and the outer diameter of the rubber mount depends on the gap between the radiator and the condenser. There was an inconvenience that reducing the size would be a major obstacle.

[0010]

SUMMARY OF THE INVENTION Therefore, in order to eliminate the above-mentioned disadvantages, the present invention provides a radiator of a cooling device and an aluminum condenser of an air conditioner in parallel at the front of a vehicle. In the mounting structure of the radiator and the capacitor, the radiator core and the radiator tank of the radiator are all made of aluminum material, and the aluminum radiator is provided with the aluminum capacitor directly attached thereto. I do.
