Abstract

The invention discloses a driving motor liquid cooling device, a manufacturing method thereof and a driving motor. The driving motor liquid cooling device includes a motor casing part, the motor casing part includes a hollow cavity formed by surrounding walls, and there is a cooling liquid channel formed by lost foam casting in the peripheral wall of the motor casing part. The coolant passage has a bent portion. The manufacturing method includes performing integral casting of the motor casing; and removing the solid model of the shape of the cooling liquid channel from the cast and formed motor casing, and integrally forming the cooling liquid channel and at least two communicating with it in the motor casing. hole. This one-piece cooling structure can solve the problems of complex assembly and difficult sealing of the existing inner and outer water jackets, reduce costs and improve production efficiency.

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...
