COOLING SYSTEM OF HYBRID VEHICLE

摘要

A cooling system of a hybrid vehicle is provided to maximize a cooling efficiency by adjusting the quantity of air which are supplied to the motor controller and a DC/DC converter. A hybrid vehicle includes a battery case(3) having a battery container(3a), a motor controller(10), and a converter(12). A blower(90) sucks in the inner air of the vehicle. An introduction duct(20) supplies the indoor air to the battery container to cool down a battery in the battery container. A first supply duct(30) supplies the air from the battery container to the converter, so that the converter is cooled down. A second supply duct(40) supplies the air from the battery container to the motor controller, so that the motor controller is cooled down. An air dividing unit divides the air from the battery container and supplies the divided air to the first and second supply ducts.
