Title:
COOLING STRUCTURE, STATOR, AXIAL MAGNETIC FIELD MOTOR, AND ASSEMBLY METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/036659
Kind Code:
A1
Abstract:
The present invention provides a cooling structure, a stator, an axial magnetic field motor and an assembly method thereof. The cooling structure comprises a cooling disc. The cooling disc comprises a rotor-facing surface, a stator-facing surface and several stator sleeve holes which penetrate through the rotor-facing surface and the stator-facing surface. Flow channel are further arranged between the rotor-facing surface and the stator-facing surface. The flow channels surround the periphery of the stator sleeve holes. The cooling disc can be built into the motor and arranged between the stator and the rotor, and then a cooling medium is introduced into the flow channels to transfer the heat of the rotor and the stator by means of the flowing cooling medium. Compared to conventional casing water channel arrangement methods, the heat transfer path between the rotor and the stator and the cooling structure is shortened, so as to effectively improve the heat dissipation effect and ensure the reliable operation of the motor.
