[0024] As shown in Figure 1 , Figure 2 and Figure 3 , the filter mechanism comprises high pressure water pump 9, filter barrel 10, screw cap 11, filter screen 12 and water valve 13, the serpentine heat pipe 3 is provided with high pressure water pump 9 on the left side, the serpentine heat pipe 3 left side upper portion is connected with filter barrel 10, the filter barrel 10 inside is connected and communicated with the inside of the serpentine heat pipe 3, the filter barrel 10 upper portion penetrates out of the top of the installation frame 1, the filter barrel 10 lower portion is provided with filter screen 12, the filter barrel 10 upper portion is threadedly connected with screw cap 11, the serpentine heat pipe 3 lower left side is connected with water valve 13, the water valve 13 outlet penetrates out of the left side of the installation frame 1.

[0027] When the device needs to be used, the staff needs to open the screw cap 11, pour the appropriate amount of cooling liquid into the filter bucket 10, and then reset the screw cap 11. The cooling liquid will first pass through the filter screen 12 and then flow into the serpentine heat exchange pipe 3. When passing through the filter screen 12, the impurities in the cooling liquid will be adsorbed to keep the inside of the pipeline clean, ensure the effective contact of the heat transfer surface, and improve the heat exchange efficiency. Then start the low-pressure water pump 8 and the liquid cooling fan 15. The low-pressure water pump 8 drives the cooling liquid to flow slowly in the serpentine heat exchange pipe 3. Then the staff injects the appropriate amount of normal temperature water or hot water into the sleeve 5 through the water inlet pipe 4. These substances will flow through each sleeve 5 and indirectly contact the cooling liquid in the serpentine heat exchange pipe 3, and the original temperature of the substances will be reduced, and the temperature of the cooling liquid will be increased. When the cooled cooling liquid flows through the fixed box 14, it will contact the liquid cooling fan 15 again. The cold air blown by the liquid cooling fan 15 will take away the temperature of the cooling liquid and be discharged to the atmosphere through the ventilation net 16, and the cycle will continue.

[0028] The water in the sleeve 5 will become low-temperature water after heat exchange, and then it will come to the copper pipe 17. Then the staff needs to start the impeller fan 18. The impeller fan 18 blows normal temperature gas. Because the copper pipe 17 has high heat conduction performance, the temperature of the copper pipe 17 will also decrease relatively when the low-temperature water flows through it. The normal temperature air blown by the impeller fan 18 will absorb the heat in the air when it contacts the low-temperature copper pipe 17, so the air blown out is cold. At the same time, the low-temperature copper pipe 17 will condense into water droplets on the surface when it meets the normal temperature air, and the water droplets will fall into the water tank 21 below and then flow out through the water outlet pipe 22. The temperature sensor 102 can monitor the temperature of the copper pipe 17 in real time, and the control valve 20 can control the flow of water to control the refrigeration effect. The low-temperature water will be discharged from the rightmost side of the copper pipe 17 after absorbing heat.

[0029] With the growth of using time, the pipe interior can accumulate scale and other sundries, the staff needs to discharge the cooling liquid in the serpentine heat exchange pipe 3 through opening the water valve 13, then closes the water valve 13 and opens the screw cap 11, then manually cleans the filter screen 12 in the filter bucket 10, after cleaning, adds proper amount of clean water and cleaning agent into the serpentine heat exchange pipe 3, then resets the screw cap 11, then starts the high-pressure water pump 9, the high-pressure water pump 9 can drive the clean water and cleaning agent to mix fully, so as to achieve the best cleaning effect, at the same time, the high-pressure water pump 9 can effectively drive the water flow to impact the sundries and dirt in the pipe, the flushing time needs to continue for about five minutes, after finishing, opens the water valve 13 to discharge the water in the pipe, at the same time, the shell mounting plate 2 is fixed by bolts, the staff can disassemble by tools, when maintaining, can need, thus completes the operation and cleaning process of the equipment.
