Abstract

The invention discloses a driving motor liquid cooling device and a manufacturing method thereof, and the driving motor. The driving motor liquid cooling device comprises a motor shell part. The motor shell part comprises a hollow cavity which is formed by a circumference wall. The circumference wall of the motor shell part possesses a cooling liquid channel formed through lost pattern casting. The cooling liquid channel possesses a bending portion. The manufacturing method comprises the following steps that integral casting molding of the motor shell is performed; a cooling liquid channel shape entity model is removed from the motor shell after casting molding; the cooling liquid channel and at least two holes which are connected with the cooling liquid channel are integrally formed in the motor shell. Because of a one-piece cooling structure, problems that existing internal and external water jacket assembling is complex and sealing is difficult to be achieved can be solved; cost is reduced and production efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of driving motors, in particular to a liquid cooling device for a driving motor, a manufacturing method thereof, and a driving motor with the liquid cooling device for a driving motor. Background technique [0002] The driving motor for electric vehicles will generate a lot of heat during operation, which will cause the components of the driving motor to heat up and the temperature will rise. The limit of the temperature rise will directly affect the service life of the driving motor. Therefore, the driving motor must be equipped with a cooling device . [0003] The existing water-cooled cooling structure for electric vehicle drive motors usually adopts the form of inner and outer water jackets and O-ring seals. For example, Chinese Invention Patent Publication No. CN101499702A discloses that a compact water-cooled three-phase asynchronous motor cooling device adopts air-water composite cooling. The cooling...
