COOLING DEVICE FOR ELECTRICAL APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a cooling device for an electrical apparatus in which dispersion of cooling efficiency is suppressed.

SOLUTION: A cooling device for an electrical apparatus comprises a refrigerant passage formation member 120 which has a flat plate shape and is connected with an inverter element included in an EV device. The refrigerant passage formation member 120 forms a refrigerant passage 32 through which a refrigerant for vehicle interior air-conditioning flows in a direction of the flat plate. The refrigerant passage 32 includes: a plurality of porous conduit parts 151 which have a porous conduit shape arranged in parallel with the flow direction of the refrigerant and are disposed spaced apart from each other; a reset space part 157 which is disposed between the porous conduit parts 151 adjacent to each other in the flow direction of the refrigerant to discharge bubbles included in the refrigerant; and a reversal space part 156 which communicates the porous conduit parts 151 adjacent to each other in the flow direction of the refrigerant to reverse the flow direction of the refrigerant between the porous conduit parts 151 adjacent to each other.
