Benefits of technology

[0020]The air-vapor separation device according to the present invention has the advantages of simple structure, convenient operation, and is reliable and effective in separation of air and refrigerant vapor, with good separation effect. The air-vapor separation device and the method thereof according to the present invention, the air may be automatically separated from the refrigerant vapor without affecting the normal cooling of the liquid-cooling system, so that not only may the original air in the liquid-cooling system pipeline be discharged, but also may the air brought into the liquid-cooling system pipeline when repairing and replacing components be discharged for the recovery of the refrigerant, thereby greatly improving the cooling effect of the liquid-cooling system.

Problems solved by technology

Most of the computers currently used rely on cold air to cool the machine, but in the data center, the air-cooling alone is not enough to meet the heat dissipation requirements for servers with high heat flux density.
It has the disadvantages of complicated heat transmission, contact thermal resistance and convection heat transfer resistance, large sum of thermal resistance, low heat transfer efficiency, large temperature difference between heat sources with high and low temperature during heat transfer, and being carried out by requiring outdoor heat sources with lower temperature to guide the heat transfer.
In addition, the working noise of the pump is generally not obvious, so the overall heat dissipation system is very quiet as compared with the air-cooling system.
And then, since the air cannot be condensed, the cooling efficiency of the liquid-cooling system will be affected.
