Separated heat radiation type novel motor based on heat pipe

Abstract

The invention relates to a separated heat radiation type novel motor based on a heat pipe. The separated heat radiation type novel motor comprises a motor core, a motor housing, a water-cooled circulating system and the heat pipe. The motor core is arranged in the motor housing. The heat pipe for heat conduction connects the motor housing with the water-cooled circulating system. The water-cooled circulating system is separated from the motor core and the motor housing. The separated heat radiation type novel motor has advantages of small integral weight, compact structure, small size and high heat radiation speed. The separated heat radiation type novel motor is particularly suitable for new-energy vehicles and belongs to the technical field of components of the 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 motor that uses a heat pipe to conduct heat generated by a motor core (motor) to a separate cooling water circulation system for heat exchange. 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 ri...

Problems solved by technology

On the one hand, it leads to complex processing of the motor casing, which significantly increases the manufacturing cost; on the other hand, it leads to an increase in the size of the motor and reduces the power density ratio; third, it increases the difficulty of sealing and complicates the system, which affects reliability

[0004] In the motor disclosed in CN103427560, heat pipes are placed in the contact part between the outer diameter of the stator core and the stator housing, between the rotor and the rotating shaft, and between the bearing and the end cover, but it does not separate the cooling water channel from the motor. If the cooling water leaks, it will risk to the motor
