Title:
COOLING LIQUID FLOW CHANNEL STRUCTURE IN ROTATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/014464
Kind Code:
A1
Abstract:
Provided is a cooling liquid flow channel structure in a rotating machine, the flow cannel structure being able to reduce pressure loss of cooling liquid flowing through a flow channel to thereby improve cooling efficiency while securing smooth flow of the cooling liquid. A cooling liquid flow channel structure, which is for cooling a motor 1 and which is provided in a cylindrical frame 2 in the motor 1, comprises: a flow channel body 11, which is provided in a wall thickness part 2a of the frame 2 so as to extend while meandering along the circumferential direction of the frame 2, and through which cooling liquid flows during cooling; and a bypass flow channel 12 which is provided so as to extend along the circumferential direction of the frame 2 at one of both ends of the frame 2 in the axial direction and to connect front-side reverse flow channel parts 15, 15 of the frame 2 in the flow channel body 11, and through which cooling water flows during cooling. The flow channel body has a plurality of straight flow channel parts 14 disposed in the circumferential direction of the frame 2 and a plurality of reverse flow channel parts 15, 16 connected to ends of the straight flow channel parts 14.
