Novel air-cooled motor based on heat pipe heat-conduction technology

Abstract

The invention relates to a novel air-cooled motor based on heat pipe heat-conduction technology. The novel air-cooled motor comprises a stator, heat pipes and a fin set. The heat pipes for heat conduction connect the stator with the fin set therebetween. The novel air-cooled motor based on the heat pipe heat-conduction technology further comprises a shaft, a rotor, magnetic steel, a winding, an end cover and a support. The shaft drives the rotor to rotate. The magnetic steel is fixed on the rotor. The winding is fixed on the stator. The stator is arranged in a manner of surrounding the rotor. The base is arranged in a manner of surrounding the stator. The end cover is fixed to the end of the base. The shaft penetrates through the end cover. The novel air-cooled motor has high heat radiation effect. A spiral water channel in the housing according to prior art is not required. The novel air-cooled motor has advantages of realizing simple and compact structure, reducing risk that cooling water accidentally enters the motor, and reducing burden of an automotive water cooling system. The novel air-cooled motor belongs to the technical field of components of new-energy vehicles.

Description

technical field [0001] The invention relates to the technical field of parts of new energy vehicles, in particular to a new type of air-cooled motor that uses a heat pipe to conduct heat generated by a motor to a fin set for forced air cooling. Background technique [0002] Vigorously developing new energy vehicles is a strategic measure to promote the transformation and upgrading of the automobile industry and build an environment-friendly society. Drive motor is the core component of new energy vehicles, and its performance has a direct and important impact on new energy vehicles. Motor operating temperature directly affects motor efficiency, reliability and service life. Excessive temperature rise will accelerate the aging of the motor insulation material and shorten the service life; the efficiency of the motor will decrease, resulting in an increase in heat generation and further pushing up the temperature rise. Therefore, temperature rise control is crucial to the ef...
