Abstract

The present invention provides a vehicle in which the discharge air released from the lower surface of a cooler body arranged at the lower part of the vehicle on the rear side of the vehicle than the rear wheels is discharged downward, so that the flow of the discharge air can be prevented as much as possible. Protects the cooler body from mud splashes, etc. from rear wheels. The bottom cover arranged on the lower side of the cooler main body is provided with an exhaust port through which the discharged air released from the lower surface of the cooler main body flows downward and is discharged to the outside, and the exhaust port extends in the vehicle width direction. A plurality of fins inclined so that the lower end is located on the vehicle rear side than the upper end are provided separately along the vehicle front-rear direction. By properly determining the length dimension (L), inclination angle (α), interval (d) and the like of the plurality of fins, the discharge air released from the lower surface of the cooler main body can be properly directed to the outside along the plurality of fins. discharge, and can protect the cooler body from splashing mud, etc. generated by the rear wheels.

Description

technical field [0001] The present invention relates to a vehicle in which a cooler main body is disposed in a lower portion of the vehicle on the rear side of the vehicle than rear wheels. Background technique [0002] There is known a vehicle in which a heat exchange type cooler main body through which a cooling medium such as oil or water flows is arranged in a lower portion of the vehicle on the rear side of the vehicle relative to the rear wheels in the vehicle front-rear direction. The vehicle described in Patent Document 1 is an example. In a vehicle in which a transaxle for driving the rear wheels is disposed at a position rearward from the center of the vehicle, a transaxle for driving the rear wheels is disposed at the lower portion of the vehicle on the rear side of the vehicle relative to the rear wheels. The cooling medium of the bridge is cooled by the cooler body. Moreover, Patent Document 2 describes a cooling technology of a differential pressure air guide ...

AI Technical Summary

Problems solved by technology

In this case, foreign objects such as stones and mud splashed by the rear wheels come into contact with the cooler body, and there is a possibility that the cooling performance may be impaired due to damage to the cooler body or clogged holes.

On the other hand, it is conceivable to arrange the bottom cover under the cooler main body, but the flow of the discharged air released from the cooler main body to the lower side is hindered, and the cooling performance may not be properly improved.

Such a problem is not limited to the differential pressure air guide type cooler device, and even in a cooler device having an outside air intake duct opening to the front of the vehicle, when the exhaust air is directed to the cooler body arranged at the lower part of the vehicle, The case of the lower discharge also produces
