Problems solved by technology

[0016] In particular, even in the case where the coolant flows through the serpentine inter-fin passages as in the heating element cooling structure described in Patent Document 4 above, since the both side wall surfaces of the heat radiation fins are formed in the same shape, the fins have the same shape. The passage width in the parallel arrangement direction of the cooling fins in the inter-fin passage is uniform, so that sufficient turbulence cannot be generated in the co...

Abstract

A heat generation body cooling structure (50) and a drive device having the heat generation body cooling structure. The heat generation body cooling structure (50) has formed in it a refrigerant space (R) and inter-fin passages (Rp). The refrigerant space (R) is formed between a heat radiation surface (53a) thermally connected to a heat generation body and an opposite surface placed so as to face the heat radiation surface (53a). The inter-fin passages (Rp) are formed by parallelly arranging heat radiation fins (56), rising from the heat radiation surface (53a) toward the opposite surface, and allow refrigerant to flow between each adjacent pair of heat radiation fins (56). A heat radiation fin (56) is shaped in a serpentine pattern having bends in the direction of flow of the refrigerant, and both side wall surfaces (56c, 56d) of the fin (56) are shaped to be different from each other.

Description

technical field [0001] The present invention relates to a heating element cooling structure and a driving device, wherein the heating element cooling structure is such that a coolant space is formed between a heat dissipation surface thermally connected to the heating element and an opposing surface arranged opposite to the heat dissipation surface, In the coolant space, a plurality of heat dissipation fins standing upright from the heat dissipation surface toward the opposing surface are arranged in parallel, inter-fin passages through which the coolant flows are formed between the plurality of heat dissipation fins adjacent to each other, and the drive device includes : Motor, housing of the drive device for housing the above motor, [0002] An inverter that controls the motor is provided with a cooling structure for the heating element, and the inverter is used as the heating element. Background technique [0003] When a motor is used as a drive source of a vehicle, the ...
