An electric actuator with high heat dissipation

Abstract

The application discloses a high-efficiency heat-dissipation electric actuator and relates to the technical field of energy-saving motors. The dynamic filling mechanism is arranged between the motor and the ring wall, the principle of the bimetallic strip changing the bending degree according to the internal temperature of the motor is used, the piston block is driven to move, the amount of the heat-conducting oil filled into the filling cavity is changed, the effective heat-conducting contact area between the motor end wall and the external ring wall and the heat-conduction efficiency are flexibly adjusted, the heat-dissipation capacity can be self-adaptively adjusted according to the real-time temperature in the motor under the condition that the motor constantly drives the water pump and the fan, the motor can be effectively ensured to work in the suitable temperature range, the problems of overheating damage, large starting resistance, low efficiency, condensation corrosion and the like are avoided, and the operation stability and the service life of the motor are remarkably improved.
