Patent ID: 11323005

Abstract:
The present invention is intended to provide: a cooling jacket device 1 which offers excellent cooling performance, is easy to manufacture and enables cost reduction; and a rotary electric machine including the cooling jacket device. The cooling jacket device includes: a plurality of jacket bodies each of which is formed in a substantially flat plate shape and includes therein a channel communicating with a pair of inlet/outlet ports formed in an outer surface of the jacket body, and allowing a refrigerant to flow therethrough; a plurality of coupling members which couple and retain the plurality of jacket bodies in conformity with an outer peripheral shape of a heat generating portion of the rotary electric machine; and a plurality of tubular members which are connected to the inlet/outlet ports, through which the refrigerant discharged from the inlet/outlet port of one of the plurality of jacket bodies is sent to the inlet/outlet port of another one of the plurality of jacket bodies so that the refrigerant flows through the channels of the plurality of jacket bodies.
