Now briefly describe the working principle of Embodiment 1:

The compressor 202, the first fan 208, the second fan 3 and the negative ion generator 401 are turned on by the controller 6, the upper electrostatic precipitator plate 403 is connected to the negative pole of the power supply, and the lower electrostatic precipitator plate 404 is connected to the positive pole of the power supply. The compressor 202 compresses the refrigerant vapor into high temperature and high pressure vapor, and the high temperature and high pressure vapor is cooled in the heat dissipation grid 204 by the first fan 208 and cooled into a low temperature and high pressure liquid. The low-temperature and high-pressure liquid flows into the liquid storage tank. Due to the pressure drop on both sides of the electromagnetic throttle valve 209 , the liquid storage tank sprays the atomized low-temperature and low-pressure liquid through the electromagnetic throttle valve 209 . The atomized low-temperature and low-pressure liquid flows into the first cooling grid 206 and the second cooling grid 207. The first cooling grid 206 cools the air blown into the computer case 1 by the second fan 3, and the second cooling grid 207 cools the CPU. Cool down. The low-temperature and low-pressure liquid absorbs heat in the first cooling grid 206 and the second cooling grid 207 to become high-temperature and low-pressure steam, and the high-temperature and low-pressure steam is compressed by the compressor 202 to become high-temperature and high-pressure steam again to complete a thermal cycle. CPU cools down. The air blown into the computer case 1 by the second fan 3 is filtered through the dust-removing cotton mesh 402 to form relatively clean air. Since the first cooling grid 206 is made of pure copper material, the surface of the first cooling grid 206 is fixed with a copper cooling cone 405 , and the first cooling grid 206 is electrically connected to the negative ion generator 401 . Therefore, the first cooling grid 206 emits negative ions through the heat dissipation cone 405 . The relatively clean air is cooled by the first cooling grid 206, and then mixed with negative ions and blown to the computer motherboard, which not only functions to warm the computer motherboard, but also eliminates static electricity on the computer motherboard, preventing the computer motherboard from being charged with static electricity. Vacuum the dust. The negative ions in the case will combine with the positively charged dust in the air in the case, and finally the neutralized positively charged dust falls on the lower electrostatic dust collector plate 404 to be collected by gravity, while the unneutralized dust is collected. Positively charged dust is attracted to the upper electrostatic precipitator plate 403 to be collected. The negatively charged dust in the air will be attracted to the lower electrostatic precipitator plate 404 to be collected. By arranging the negative ion generator 401 , the upper electrostatic precipitator plate 403 and the lower electrostatic precipitator plate 404 , the air in the computer case 1 can be purified for a second time, thereby having a better dust removal effect. The copper heat dissipation cone 405 fixed on the surface of the first cooling grid 206 can not only play the role of emitting negative ions, but also increase the heat dissipation area of the first cooling grid 206, so that the first cooling grid 206 has a higher heat exchange efficiency.

Through liquid cooling, it has higher heat dissipation efficiency, and can centrally cool the CPU, the main heat source in the computer motherboard, to ensure that the CPU works in the best temperature environment, thereby improving the performance of the CPU. It avoids the vibration and noise caused by increasing the power of the fan in order to improve the heat dissipation efficiency; through electrostatic dust removal, the air filtered by the dust removal cotton net 402 can be dedusted twice, which greatly improves the dust removal effect.
