The water pump cabinet inlet 3 and water pump cabinet outlet 6 of the water pump cabinet structure are respectively connected to the primary side pipeline. The coolant in the primary side pipeline enters the inlet pipe 2 through the water pump cabinet inlet 3 under the drive of the water pump 4. Under the action of the constant pressure expansion tank 7, the medium pressure is kept constant. The coolant is discharged from the water pump cabinet outlet 6 through the outlet pipe 5 and circulates back into the primary side pipeline. A flow sensor is installed on the primary side pipeline outside the entire water pump cabinet structure. When the flow sensor detects that the medium in the primary side pipeline is low, liquid can be replenished through the replenishment tank 8. During replenishment, the coolant in the replenishment tank 8 is drawn out through the connecting pipe 11 under the drive of the replenishment pump 12 and injected into the inlet pipe 2, thereby replenishing the primary side pipeline, realizing the automatic replenishment function. The safety relief valve 9 on the outlet pipe 5 monitors the pipeline pressure in real time.
