Title:
ROTATING ELECTRICAL MACHINE
Document Type and Number:
WIPO Patent Application WO/2022/190183
Kind Code:
A1
Abstract:
This rotating electrical machine comprises a cylindrical housing having a flow path through which a refrigerant circulates, an inlet from which the refrigerant flows in the flow path, and an outlet from which the refrigerant flows out from the flow path, wherein the flow path is formed so as to extend around the circumferential surface of the housing in a spiral shape. The flow path comprises: a first flow path formed along one end surface of the housing and formed so that the width along the circumferential surface increases from the inlet along the circulation direction of the refrigerant; and a second flow path formed along the other end surface of the housing and formed so that the width along the circumferential surface reduces down to the outlet along the circulation direction of the refrigerant.
