Abstract

The invention discloses an externally-closed heat-radiating system of a motor, belonging to the field of motor industries. The externally-closed heat-radiating system of the motor comprises a base, a stator, a rotor, a front end cover, a back end cover, a fan housing, an air pipe, an air blower and a base air hole. The externally-closed heat-radiating system is characterized in that the base, the stator, the rotor, the front end cover and the back end cover form the motor body. The fan housing is pressure-tight and is clamped on the base, and an air intake arranged on the fan housing is connected with the air pipe. The base air hole is formed by the base, a heat dissipation rib and a welding board, one end of the base air hole is connected with atmosphere, and the other end of the base air hole is connected with an inner cavity of the fan housing. One end of the air pipe is connected with the air blower, and the other end of the air pipe is connected with the fan housing. In the invention, through measures of increasing cooling air flow, enlarging heat dissipation area, improving cooling air efficiency and the like, the effect of reducing temperature rise is achieved. The invention can be used in the industry such as car motors, compact type motors and the like with high power density requirements.

Description

technical field [0001] The invention belongs to the technical field of electric motors for mechanical drive equipment, and in particular relates to a brand-new closed heat dissipation system outside the electric motor. Background technique [0002] For motors used as mechanical drive equipment, the temperature rise of the motor has always been an important assessment item. The place where the motor is used, the load condition and its own performance requirements all have a great influence on the temperature rise. In some cases, relying solely on the heat dissipation capability of the motor itself cannot effectively dissipate heat, resulting in excessive temperature rise of the motor, damage to the motor insulation, shortened life span, or even burnt out. Contents of the invention [0003] The purpose of the invention is to provide a brand-new closed heat dissipation system outside the motor. By increasing the flow of cooling air, enlarging the heat dissipation area, and ...
