Abstract
A cooling system is provided for an electric vehicle inverter system having an inverter for converting electric power from a battery into alternating current and for supplying the current to a driving motor for driving the vehicle. The cooling system employs a heat sink having an internal coolant flow passage for conducting a liquid coolant which is forced to recirculate. The heat sink is vertically placed on a mounting base, and heat generating parts are placed and fixed on at least one side of said heat sink. In this way, a cooling system for an electric vehicle inverter system which is small in size and large in cooling capacity with a simple construction is easily provided.
