Description

Technical Field

[0001] This utility model belongs to the field of motor housing technology, and more specifically, it relates to a motor heat dissipation protection housing with temperature monitoring function. Background Technology

[0002] An electric motor is a key device that converts electrical energy into mechanical energy. During operation, a large amount of heat is inevitably generated due to resistance losses caused by current passing through the coil, hysteresis losses of the iron core, and eddy current losses. If this heat cannot be dissipated in a timely and effective manner, the internal temperature of the motor will continue to rise.

[0003] Traditional motor cooling methods mainly rely on natural heat dissipation combined with forced air cooling by fans. Natural heat dissipation dissipates heat through heat conduction, convection, and radiation between the motor casing and the surrounding air. Forced air cooling by fans accelerates airflow by rotating the fan blades driven by the motor shaft, thereby removing heat from the motor and achieving the purpose of heat dissipation. However, this combination of methods lacks effective temperature monitoring and automatic control functions. It is impossible to accurately monitor the temperature changes inside the motor in real time, and the heat dissipation strategy cannot be adjusted in a timely manner according to the actual temperature of the motor, resulting in an inaccurate and inefficient heat dissipation process, making it difficult to achieve the best heat dissipation effect.

[0027] The specific usage and function of this embodiment are as follows: In this invention, during use, the front cover 201 and the rear cover 301 are fixed to both sides of the motor housing 1 with bolts to ensure a firm connection; then, the front bearing seat 203, the rear bearing seat 302, and the rear ventilation cover 303 are installed sequentially with bolts; during motor operation, the temperature sensor 305 continuously monitors the temperature changes inside the motor housing 1; the temperature sensor 305 feeds back the temperature information to the control module 403 in real time, and the control module 403 automatically adjusts the operating status of the circulation pump 404 according to the preset temperature threshold; when the internal temperature of the motor housing 1 rises, the control module 403 automatically starts the circulation pump 404 to enhance the heat dissipation effect; when the internal temperature of the motor housing 1 drops to a suitable range, the control module 403 shuts down the circulation pump 404 to avoid over-cooling and energy waste; by opening the pipe cap 4010 of the liquid inlet pipe 407, liquid can be injected into the storage tank 401 through the liquid inlet pipe 407.
