Problems solved by technology

[0007] However, in such a cooler device for a vehicle, when the outside air intake duct is attached to the cooler main body so as to extend toward the rear side of the vehicle than the cooler main body, if the outside air intake duct reaches the side of the vehicle, Near the rear end, when the vehicle collides from the rear or collides with an obstacle when it is retreating, the collision load directly acts on the cooler body from the outside air inlet channel, and there is a possibility that the cooler body is damaged and the cooling medium leaks out. possibility

Embodiment

[0052] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that in the following embodiments, the drawings are appropriately simplified or deformed for explanation, and the dimensional ratio and shape of each part may not be accurately drawn.

[0053] figure 1 It is a schematic diagram of a vehicle 12 equipped with a vehicle cooler device 10 according to an embodiment of the present invention. The vehicle 12 generates power through a fuel cell and is powered by an electric motor M (refer to figure 2 ) generates driving force, and in a fuel cell type electric vehicle that drives the rear wheels 14 to rotate, the vehicle cooler device 10 is arranged in the vehicle front and rear direction together with the hydrogen tank 16 filled with hydrogen as the fuel of the fuel cell. It is located on the vehicle rear side of the rear wheel 14 . The vehicle cooler device 10 cools oil as a cooling medium by exch...

Abstract

It is an object of the present disclosure to provide a cooling device of a vehicle. In a cooling device for a vehicle in which an air intake duct extends backwardly from a cooler body, a collision load generated during rear collision of the vehicle is prevented from working on the cooler body directly from the air intake duct and causing damage to the cooler body. The intake duct (air intake duct)can be arranged on the upper side of the cooler body in a manner of being capable of moving to the front side of the vehicle relative to the cooler body. The cooler body is attached to a floor via acooler installation bracket, while the air intake duct is attached to the cooler body, such that a strength of attachment of the air intake duct is lower than a strength of attachment of the cooler body. Thus, when a collision load (Fr) is applied to the intake duct, the intake duct can be separated from the cooler body and move relatively to the front side of the vehicle, so that the collision load working on the cooler body is reduced and the problem that the cooler body is damaged and a cooling medium leaks is solved.

Description

technical field [0001] The present invention relates to a cooler device for a vehicle, and more particularly to an improvement of a cooler device for a vehicle in which a cooler body and an outside air intake passage are arranged on the rear side of a vehicle. Background technique [0002] There are known a heat exchange type cooler main body through which a cooling medium such as oil or water flows, and an outside air intake passage for guiding outside air for cooling the cooling medium through heat exchange into the cooler main body. A cooler device for a vehicle arranged on the rear side of the vehicle. The device described in Patent Document 1 is an example. In a vehicle in which a transaxle for driving the rear wheels is disposed on the rear side of the vehicle central portion, a transaxle for driving the rear wheels is disposed on the rear portion of the vehicle on the rear side of the transaxle. The cooling medium of the bridge is cooled by the cooler body. Moreover...
