摘要：

PROBLEM TO BE SOLVED: To improve cooling efficiency in a power converter mounted with high density.;SOLUTION: The power converter for a vehicle includes a vessel for housing a

semiconductor element, a driver circuit, a control circuit and a capacitor, a

refrigerant housed in the vessel under a gas-liquid two-phase state, and a heat exchanger condensing the refrigerant in a gas-phase state to one in a liquid-phase state and being used for exchanging heat with the outside. In the power converter for the vehicle, the semiconductor element, the driver circuit, the control circuit and the capacitor are arranged in the state immersed in the refrigerant while the power converter is loaded on the vehicle. In the power converter for the vehicle, the heat exchanger is arranged on the wall side of the vessel forming a gas-phase space.;COPYRIGHT:
