Description

Technical Field

[0001] This invention relates to the field of motor heat dissipation technology, and in particular to an intelligent motor heat dissipation system and control method based on thermal control. Specifically, by monitoring the temperature of the motor body in real time, the system automatically adjusts the working state of the heat dissipation unit, thereby optimizing the motor cooling effect and improving the motor's working efficiency and service life. Background Technology

[0002] With the continuous development of motor technology, the application fields of motors have gradually expanded, especially in high-power, high-load industrial motors, where motor heat dissipation has become an increasingly prominent issue. Traditional motor heat dissipation methods mainly rely on fans or natural ventilation, but these methods usually cannot accurately adjust heat dissipation according to changes in motor load and operating environment, thus affecting the stable operation and service life of the motor.

[0003] Therefore, developing an intelligent motor cooling system that can monitor motor temperature in real time and automatically adjust heat dissipation capacity according to operating conditions has become an important direction for improving motor performance and extending service life. Summary of the Invention

[0004] The purpose of this invention is to provide a thermally-controlled intelligent heat dissipation system for motors and its control method, which can monitor the temperature of the motor body in real time and automatically adjust the working state of the heat dissipation unit according to different working states, thereby optimizing the heat dissipation effect of the motor, reducing temperature fluctuations, and improving the efficiency and lifespan of the motor.

[0005] To achieve the above objectives, this invention provides an intelligent heat dissipation system for motors based on thermal control. The system includes a motor body, at least one thermal sensor, multiple heat dissipation units, and a control module. The motor body has a rotating part and a fixed part. The rotating part is installed inside the motor housing and contacts the external environment, while the fixed part is installed inside the motor housing and provides a heat conduction path. Multiple heat dissipation units are arranged at different positions on the motor body. The thermal sensor is used to monitor the temperature of different areas of the motor body in real time. The control module is connected to the thermal sensor and can adjust the operating state of the corresponding heat dissipation unit according to the temperature of different areas. Each heat dissipation unit includes at least one heat exchange element with an adjustable heat dissipation area. The control module optimizes the heat dissipation effect of the motor body by adjusting the heat dissipation area or heat dissipation efficiency of the heat dissipation unit, thereby effectively reducing the motor's operating temperature and extending its service life.

[0006] The thermistor is a negative temperature coefficient thermistor, which can automatically adjust its resistance value according to the temperature change inside the motor. The control module obtains the temperature data of various parts inside the motor in real time by monitoring the resistance change of the thermistor.

[0007] Multiple heat dissipation units include fan cooling modules and liquid cooling modules. The fan cooling module is used to force airflow and accelerate heat dissipation, while the liquid cooling module removes heat through liquid flow. The control module selects the operating state of the fan or liquid cooling module based on temperature data and adjusts its operating efficiency to provide the required heat dissipation capacity according to the temperature changes of the motor's operating environment.

[0008] The heat dissipation efficiency of the heat dissipation unit is adjusted by changes in fan speed, liquid cooling flow rate, or heat dissipation area. The control module can adjust the working state of the heat dissipation unit according to the load changes and running time of the motor body, so that the heat dissipation effect always maintains the best match with the motor load and temperature fluctuations.

[0009] The heat exchange element of the heat dissipation unit includes multiple adjustable heat dissipation fins. The opening degree of the heat dissipation fins is adjusted in real time by the control module according to the temperature signal inside the motor. The change in the fin opening degree directly affects the heat dissipation area, thereby optimizing the heat dissipation effect.

[0010] The system also includes an energy recovery module, which collects the heat generated during the heat dissipation process and converts the heat into electrical energy through the thermoelectric effect, supplying power to the control module or other electrical components, thereby improving the overall energy efficiency of the system.

[0011] The method includes the following steps:

[0012] S100 monitors the temperature data of various parts of the motor body in real time;

[0013] S200 calculates the operating parameters of the heat dissipation unit that need to be adjusted based on the temperature information of each area;

[0014] The S300 allows for adjustment of the operating status of the heat dissipation unit via a control module, including adjusting fan speed, liquid cooling flow rate, and the opening of the heat dissipation fins, or selecting different heat dissipation units to operate.

[0015] The S400 further adjusts the efficiency of the heat dissipation unit based on changes in motor load and operating time to ensure that the motor remains within its optimal operating temperature range.

[0016] The method also includes step S500, whereby when the motor load increases, the system automatically enhances the heat dissipation capacity by increasing the fan speed or increasing the liquid cooling flow rate to ensure that the internal temperature of the motor does not exceed the set safety threshold.

[0017] The system also includes a heat recovery module that can convert heat generated during the heat dissipation process into electrical energy. The recovered electrical energy is then used to power the motor or other components, thereby improving the overall energy efficiency of the system.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. Precise heat dissipation regulation: Through thermistor sensors and real-time temperature monitoring, precise matching between motor temperature and heat dissipation capacity is achieved;

[0020] 2. Improve motor efficiency: A combination of air cooling and liquid cooling is used to ensure that the motor can maintain stable operation under high load;

[0021] 3. Energy recovery: The heat generated during the heat dissipation process is converted into electrical energy through the heat recovery module, further improving the overall energy efficiency of the system;

[0022] 4. Extended service life: The precise temperature control system effectively reduces the risk of motor overheating, thereby extending the motor's service life. Attached Figure Description
