Cooling system

Abstract

A cooling system includes: an integrated unit in which an electric vehicle drive unit including at least an electric motor configured to transmit a drive rotational force to a traveling system of a vehicle and an electronic circuit unit including at least an electronic circuit configured to drive the electric motor are integrated; a cooling channel through which a coolant circulates to the electronic circuit unit; and an oil channel that includes a heat exchanger configured to exchange heat with the coolant circulating through the cooling channel and through which oil circulates to the electric vehicle drive unit. The heat exchanger is disposed inside the integrated unit between the electric vehicle drive unit and the electronic circuit unit.
