Abstract

The invention provides a cooling flow channel structure and a stator assembly. The cooling flow channel structure comprises a cooling inlet, a cooling outlet and a flow channel communicated between the cooling inlet and the cooling outlet, shunting pieces are arranged on the inner side wall and the outer side wall of the flow channel at intervals, each shunting piece comprises a shunting part and a connecting part, the shunting part is connected with the inner side wall and the outer side wall of the flow channel through the connecting part, a to-be-cooled piece is fixed to the shunting part, and a vortex part is formed between the to-be-cooled piece and the connecting part, so that the cooling medium passing through the vortex part forms longitudinal vortex, the heat exchange efficiency of the to-be-cooled piece is improved, and the cooling performance is improved.

Description

technical field [0001] The invention relates to the field of heat exchange, in particular to a cooling channel structure and a stator assembly. Background technique [0002] With the development of new energy vehicles and other industries, the performance requirements of motors are getting higher and higher, especially the power density and torque density of motors are required to be greatly improved. The key to restricting the improvement of motor power density and torque density is the heat dissipation capacity of the motor. Once the heat dissipation is insufficient, the internal temperature of the motor will rise higher, resulting in damage to the insulation layer and demagnetization of the permanent magnet, which will affect the performance of the motor. [0003] The main heat-generating components of the motor are the stator core, etc., and the existing cooling method is to arrange water channels on the casing to exchange heat for the heat-generating components, so as t...
