[0001]

BACKGROUND OF THE INVENTION The present invention is mainly used for automobile radiators.
The present invention relates to a structure for attaching a compressor and a condenser of an automobile air conditioner to a vehicle body or the like.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 3, a radiator 100 for an automobile is equipped with dedicated mounting mounts 30 and 40.
Further, the condenser 200 is attached to the vehicle bodies 5 and 6 separately from each other by the dedicated attachment members 50 and 60.

Further, the one disclosed in Japanese Utility Model Laid-Open No. 4-29409 has a structure in which a condenser is supported and attached to a radiator for an automobile, and the radiator for the automobile is used.
The condenser mounting part is integrally formed on a part of the tank
On the other hand, a mounting member is separately attached to the condenser.

[0004]

However, in the former prior art (FIG. 3), since the radiator 100 and the condenser 200 are separately mounted, the dedicated mounting members 30, 40, 50 are respectively mounted. , 60 must be used, which causes a problem of increasing the number of parts and the number of working steps.

Further, in the latter case where the condenser is attached to the radiator, the shape of the tank portion of the automobile radiator must be changed, and the attachment member must be attached to the condenser separately. This is a cause of an increase in the number of parts and man-hours.

An object of the present invention is to realize the integration of an automobile radiator and a condenser with a simple structure without changing the shape of an existing product, increasing the number of parts, and increasing the number of working steps. To do.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a strength member itself which is integrally provided with elastic members mounted on the upper and lower parts of a radiator for a vehicle. A more projecting portion is formed, a condenser mounting portion is formed by this projecting portion, and the automobile radiator and the condenser are integrated by this condenser mounting portion.

[0008]

In the present invention, since the condenser mounting portion is provided on the projecting portion of the strength member of the radiator mounting mount, the automobile radiator without newly increasing the number of parts or changing the shape of the conventional product. -It has become possible to assemble the compressor and condenser together. In addition, since the same radiator mounting mount supports the radiator and condenser, the mass supported by one mount increases, the resonance point changes, and the vehicle vibration balance changes, reducing steering vibration. The effect of reducing vehicle vibration can be brought about.
