COOLING DEVICE FOR ELECTRIC EQUIPMENT

摘要

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

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 to form a heat transfer medium space arranged between said first surface and said second surface and transfers heat generated at said heat source; a fin portion which is provided at said second surface and radiates heat transferred through said heat transfer member; 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 a supplying/discharging unit which supplies and discharges a heat transfer medium, which is different from a coolant flowing through said coolant passage, to and from said heat transfer medium space, 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.
