Specifically, the cooling water in the cooling water tank 01 flows out from the water outlet 11 of the cooling water tank 01 under the driving of the flow control device 03, flows through the cooling pipeline 02 to cool the electrical equipment, and flows back to the cooling water tank 01 from the water inlet 12 of the cooling water tank 01 to be cooled after absorbing the heat of the electrical equipment. As shown in fig. 1, the motor apparatus in this embodiment includes a motor and a speed reducer, and cooling water flows out of the cooling water tank 01 and then sequentially passes through the motor and the speed reducer to cool the motor.
This application is through setting up temperature-detecting device 05 in cooling pipeline 02, detects the temperature of cooling water in cooling pipeline 02, and the temperature of cooling water can effectively reflect electrical equipment's temperature condition, and master control set 04 sends control signal to flow control device 03 according to the temperature data that temperature-detecting device 05 detected, and flow control device 03 adjusts the flow of cooling water in real time.
As an example, when the temperature data detected by the temperature detecting device 05 is greater than the upper limit temperature threshold, the main control device 04 sends a signal for increasing the flow rate to the flow rate control device 03, so as to increase the flow rate of the cooling water, thereby improving the cooling effect; when the temperature detection device 05 detects that the temperature data is smaller than the lower limit temperature threshold, the main control device 04 sends a flow rate reduction signal to the flow rate control device 03 to reduce the flow rate of the cooling water, so as to reduce energy consumption.
Specific values of the upper limit temperature threshold and the lower limit temperature threshold are set according to the installation position of the temperature detection device 05 and the normal operating temperature of the motor apparatus.

Further, the control unit further comprises a water pressure detection device 06 installed on the cooling pipeline 02, and the water pressure detection device 06 is in communication connection with the main control device 04.

The water inlet end of the cooling pipeline 02 is close to the flow control device 03, and the flow condition in the cooling pipeline 02 can be accurately reflected.
For example, when the temperature detection device 05 detects that the temperature data is greater than the upper limit temperature threshold, the main control device 04 sends a flow rate increase signal to the flow rate control device 03, and then the main control device 04 detects whether the flow rate of the cooling water reaches the set flow rate value through the water pressure data fed back in real time by the water pressure detection device 06, and if so, controls the flow rate control device 03 to stop increasing the flow rate, so as to maintain the flow rate of the cooling water at the set flow rate value. When the temperature data is smaller than the lower limit temperature threshold, the steps are the same as the previous steps, and are not repeated.
Specifically, a water inlet pipeline 22 is connected between the water inlet end of the cooling pipeline 02 and the water outlet 11 of the cooling water tank 01, and the water pressure detection device 06 is installed on the inner wall of the water inlet pipeline 22.
