Embodiment Construction

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] The present invention provides a cooling structure for an electric motor. For details, refer to figure 1 , including the outer casing, the front and rear covers connected with the outer casing, and the motor shaft arranged in the outer casing. The motor shaft is provided with a rotor, a stator and an armature winding. The difference is: the outer casing is provided with an inner casing, the inner casing and the outer casing are nested, the inner casing is provided with a number of axially distr...

Abstract

The invention relates to a cooling structure for a motor. An inner-layer casing is arranged in an outer-layer casing. The inner-layer casing and the outer-layer casing are nested. The inner-layer casing is provided with a plurality of axially distributed grooves, and semiconductor chilling plates are arranged in the grooves. Radial-flow blades and axial-flow blades are arranged at the front end and the rear end of a motor shaft respectively, and vent holes are formed in the rear end cover. In implementation, the inner-layer casing and the outer-layer casing of the motor are nested, the inner-layer casing is provided with a plurality of axially-distributed grooves, the semiconductor chilling plates are arranged in the grooves and matched with the air cooling structure to form flow channel airflow, the effect of rapid refrigeration and heat dissipation can be achieved, and the refrigeration effect is very excellent.

Description

technical field [0001] The invention relates to the technical field of motor cooling, in particular to a cooling structure for a motor, in particular to a combined motor cooling structure of semiconductor refrigeration and air-cooled refrigeration. Background technique [0002] During the operation of the motor, the heat caused by the copper loss of the coil, the loss of the iron core and the wind friction loss of the rotor causes the temperature of the various parts of the motor to rise. When the temperature rise of the motor parts is too high, it will affect the service life of the motor and even cause the motor Faults, especially when the motor is small or running at a high speed, it is more difficult for the motor to dissipate heat, and the requirements for the motor cooling system are higher. Commonly used motor cooling methods include air cooling, water cooling and oil cooling. The single air cooling method has low cooling efficiency and limited heat dissipation capaci...
