A cooling device for electric equipment includes a cooling unit (30) for cooling inverter elements (110). Cooling unit (30) includes a heat mass (130) which has a surface (131) provided with the inverter elements (110) and a back surface (136) arranged on a back side of surface (131) to form a heat mass inner tank (150) arranged between the surface (131) and the back surface (136) and transfers heat generated at the inverter elements (110), a fin portion (140) which is provided on the back surface (136) and radiates heat transferred through the heat mass (130), air-conditioner coolant pipelines (120) which are provided on the surface (131) and form a coolant passage (32) through which a coolant for vehicle cabin air-conditioning flows, and a water pump (158) which supplies and discharges coolant water to and from the heat mass inner tank (150). With such a configuration, a cooling device for electric equipment which is excellent in cooling efficiency is provided. |
