Abstract

The invention provides a motor cooling casing, a motor and a vehicle, the motor cooling casing comprises a casing body, a cooling flow channel is arranged in the casing body, and the cooling flow channel is formed by flow channel ribs which are arranged at intervals in a surrounding mode in the axial direction of the casing body. The runner ribs comprise a plurality of annular rib sections extending in the circumferential direction of the machine shell body and connecting rib sections capable of connecting every two adjacent annular rib sections, and the annular rib sections are in a sine curve shape after being unfolded in the circumferential direction of the machine shell body. According to the invention, cooling liquid flowing into the cooling flow channel can flow more rapidly, the flow speed of the cooling liquid is higher, and meanwhile, on one hand, the annular rib sections in the sine curve shape can increase the heat exchange contact area so as to improve the heat exchange efficiency; and on the other hand, a more reliable supporting structure can be formed between the inner side and the outer side of the machine shell body, and therefore the structural strength of the machine shell body is improved.

Description

technical field [0001] The invention belongs to the technical field of motor manufacturing, and in particular relates to a motor cooling casing, a motor and a vehicle. Background technique [0002] With the continuous development of the new energy vehicle industry, the main drive motor used in electric vehicles is also evolving iteratively, and the current market has gradually adopted permanent magnet synchronous motors as the mainstream solution. The actual working conditions of electric vehicles are harsh and complicated. Under the working conditions of rapid acceleration and long-slope low-speed cruising, the motor needs to output a huge torque. temperature, extreme conditions can cause damage to the motor. Therefore, the vast majority of electric vehicle main drive motors do not use air cooling but use more efficient water cooling. [0003] Excessive temperature rise of the motor has two effects. On the one hand, the temperature resistance of the winding insulation gen...
