Embodiment Construction

[0030] The present invention will be described in further detail below.

[0031] A heat pipe-based novel motor with separated heat dissipation includes a motor core, a motor case, a water-cooling circulation system, and a heat pipe.

[0032] The motor core is a permanent magnet drive motor.

[0033] The motor casing is cylindrical and tightly wrapped around the motor core. The motor casing is made of aluminum alloy. The groove inside (inside the wall) is cast or removed. The groove is processed into a round groove or a square groove to adapt to a cylindrical heat pipe or a flat heat pipe.

[0034] The water-cooling circulation system includes a shell, which is provided with a water inlet and a water outlet, and a mounting groove is arranged in the wall of the shell; one end of the heat pipe is inserted into the bar-shaped mounting groove, and is tightly connected with the shell through an expansion process. The outer shell is surrounded by a water tank. The outer shell is ma...

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...
