Abstract

The invention provides a driving motor liquid cooling device and a driving motor, comprising: a plurality of cavities are arranged between the inner wall of the first casing body and the outer wall of the first casing body along the axial direction of the first casing body A plurality of hollow first protrusions are arranged on the outer side of the inner wall of the first casing body corresponding to the cavity, and a plurality of hollow second protrusions are arranged on the inner side of the outer wall of the first casing body corresponding to the cavity, and the plurality of first The length of the protrusion and the plurality of second protrusions along the axial direction of the first housing body is smaller than the length of the first housing body, wherein a plurality of hollow first protrusions and The plurality of hollow second protrusions can effectively increase the contact heat transfer area between the cooling liquid and the casing, effectively improve the heat dissipation performance, and ensure the safety of the driving motor.

Description

technical field [0001] The invention relates to automobile construction technology, in particular to a driving motor liquid cooling device and a driving motor. Background technique [0002] At present, in order to protect the living environment of human beings and save non-renewable resources, the energy consumption structure must be changed to avoid the energy crisis. Therefore, new energy vehicles play an important role in the current situation. [0003] As the drive motor at the heart of electric vehicles, due to its small size and high power density, the drive motor will generate a lot of heat when it is working, resulting in a high temperature rise of the motor, accelerating the aging of the insulation, and affecting the safe and stable operation of the motor. Therefore, the heat dissipation of the drive motor is particularly important in electric vehicles. [0004] In the prior art, in order to control the temperature rise of the driving motor, the casing of the driv...
