Abstract

A cooling device for electric equipment includes a cooling unit for cooling an inverter element as a heat source. The cooling unit has a surface on which the inverter element is provided and a back surface disposed on a back side of surface, and includes a heat mass for transferring heat generated by the inverter element, an air-cooling fin provided on the back surface and radiating heat transferred through the heat mass, and an air-conditioner coolant pipeline provided on the surface and forming a coolant passage through which the coolant for vehicle cabin air-conditioning flows. With such configuration, a cooling device for electric equipment excellent in the cooling efficiency is achieved.
