Heat dissipation assembly for motor housing, and motor housing comprising same

Abstract

The invention relates to the technical field of motor housings, in particular to a heat dissipation assembly for a motor housing, and the motor housing comprising the same. The heat dissipation assembly comprises a three-layer structure: a heat tube, a heat dissipation housing, and cooling fins. The heat dissipation housing is coaxial with the motor housing, and is disposed outside the motor housing. The heat tube is disposed in an interlayer between the external surface of the motor housing and the internal surface of the heat dissipation housing. The heat tube is arranged in the radial direction of the periphery of the motor housing, and the cooling fins are disposed on the external surface of the heat dissipation housing, are parallel to the motor housing, and are distributed in the axial direction of the periphery of the external surface of the heat dissipation housing. The heat dissipation assembly of the motor housing guarantees the sealing performance of the motor housing and the structural integrity while guaranteeing the heat dissipation performance. Moreover, the heat dissipation assembly is low in manufacturing difficulty, is convenient to assemble, and is good in marketprospect. The technical scheme is suitable for a common motor, and is especially suitable for a new-energy automobile motor.

Description

technical field [0001] The invention relates to the technical field of motor casings, and more specifically, to a heat dissipation assembly of a motor casing and a motor casing including the same. Background technique [0002] At present, with the rapid development of my country's industrial technology, motors are widely used as power sources for electrical appliances, vehicles and various other machinery. The motor is usually composed of housing, stator, rotor and other components. The inner wall of the motor housing is fixed with a stator, and the rotor is embedded in the stator. After the power is turned on, the rotor drives the rotating shaft to rotate to complete the power output. Motors, especially high-power motors, often generate a lot of heat when they are working. If they cannot dissipate heat in time, they will burn out the motor or accelerate the damage of the motor. Therefore, in the development and use of the motor, the heat dissipation system of the motor is ...

Problems solved by technology

However, various water-cooling systems are prone to water leakage in practice, and require high sealing performance. It is difficult to process the once-molded closed cavity pipeline, which leads to high cost of the motor casing, and the weight of the motor is increased by the cooling pipeline and water pump. and design difficulty, the actual use effect is not ideal
