COOLING DEVICE FOR ELECTRIC EQUIPMENT

摘要

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.

主权项

1. A cooling device for electric equipment mounted in a vehicle, comprising:
a cooling unit for cooling a heat source included in electric equipment, said cooling unit including: a heat transfer member which has a first surface provided with said heat source and a second surface arranged on a back side of said first surface and transfers heat generated in said heat source; a fin portion which is provided at said second surface and radiates heat transferred through said heat transfer member; and a coolant passage forming member which is provided at said first surface and forms a coolant passage allowing a coolant for vehicle cabin air-conditioning to flow, and said heat source and said fin portion being arranged on opposite sides across said heat transfer member, and said coolant passage forming member and said fin portion being arranged on opposite sides across said heat transfer member.
