this patent adopts water as the medium, makes hydrologic cycle through circulating pump 3, and water flows back from the target equipment, from return water mouth 5 entering circulation, and the water after the accuse temperature is supplied to the target equipment from delivery port 6. When the temperature detection device 9 detects that the water temperature is too low, the control system controls the electric heater to heat the circulating water, and the water temperature can reach 125 ℃ due to the pressure of the water. When the temperature detection device 9 detects that the water temperature is too high, the control system opens the electromagnetic valve 19, the cooling liquid enters the heat exchanger 2 from the cooling liquid inlet 7 to exchange water with the water in the circulating loop, and the temperature of the circulating water is reduced.
