[0048] Liquid cooler 1;

[0049] The moving mechanism 2 comprises support rods 201 symmetrically arranged on the front and rear outer walls of the liquid cooler 1;

[0050] The circulation mechanism 3 includes a connecting frame 301;

[0051] The filter cleaning mechanism 4 includes a slide slot 401 provided on the connecting frame 301;

[0052] The heat exchange mechanism 5 comprises a closed liquid tank 501 arranged at the upper end of the inner cavity of the liquid cooler 1, a bracket 502 is arranged in the inner cavity of the closed liquid tank 501, a partition plate is arranged at the upper end of the bracket 502, and a thermosiphon 503 is arranged in the inner cavity of the closed liquid tank 501;

[0053] The liquid tank mechanism 7 comprises a machine tool liquid tank 701 arranged at the lower end of the inner cavity of the liquid cooling machine 1, an inner liquid temperature sensor 702 is arranged outside the machine tool liquid tank 701, and an inlet liquid temperature sensor 703 is connected between the closed liquid tank 501 and the evaporator 8;

[0054] A liquid supply pump 6 is connected between the closed liquid tank 501 and the machine tool liquid tank 701;

[0055] The evaporator 8 is arranged at the output end of the closed liquid tank 501, and the output end of the evaporator 8 is connected to the condenser 11;

[0056] The liquid temperature can be adjusted, and the following steps are announced;

[0057] The fan of the heat pipe heat exchanger of the liquid cooler 1 works according to the detected liquid temperature in the liquid tank. When the liquid temperature is higher than the set liquid temperature T1+3°C, the fan starts to cool the liquid. When the liquid temperature is lower than the set value T1, it stops working. The forced cooling part of the liquid cooler 1 works according to the detected liquid temperature at the inlet of the evaporator 8. When the liquid temperature is higher than another set value T2+3°C, the refrigeration system starts to cool the liquid flowing through the evaporator 8. When the liquid temperature is lower than the set value T2, the refrigeration system stops working. T2<T1, the lower half of the heat pipe heat exchanger is immersed in a closed liquid tank 501, and the liquid is cooled in the liquid tank and then immersed in the forced cooling plate evaporator; the top of the closed liquid tank 501 is provided with an automatic exhaust valve for exhausting the air in the tank.
