Abstract
A cooling system for hybrid vehicles is provided with a battery case with a battery storage room for receiving a battery, a motor control unit for controlling an electric motor and a DC-DC converter for converting a voltage of the battery. The cooling system includes a blower for drawing an air existing in a passenger compartment of a vehicle, an introduction duct through which the air is introduced into the battery storage room to cool the battery, a first supply duct through which the air is supplied from the battery storage room to the DC-DC converter to cool the latter, a second supply duct through which the air is supplied from the battery storage room to the motor control unit to cool the latter, and an air distributor means for distributing the air flowing out of the battery storage room to the first supply duct and the second supply duct.
