Liquid-cooled server, a server that dissipates heat by injecting liquid, works on the principle of using heat exchange to take away the heat of the server. According to the physical form of the server, liquid-cooled servers can be divided into two categories: cold plate liquid-cooled servers and fully immersed liquid-cooled servers.
Cold plate liquid cooling technology uses working fluid as a medium for heat transfer to transfer the heat in the server from the heat source area to a distant place for cooling. In this technology, the working liquid is separated from the electronic device being cooled, and it transfers the heat of the device to the refrigerant through efficient heat conduction components such as liquid cold plates. Therefore, cold plate liquid cooling is also called indirect liquid cooling. Since the coolant can directly act on the heat source and the specific heat capacity of the liquid is much greater than that of the air, its heat dissipation speed is much faster than that of the air, thereby greatly improving the cooling efficiency. The heat dissipation per unit volume, that is, the heat dissipation efficiency is up to 1000 times, which is very suitable for solving the heat dissipation problem of high-density servers, while also reducing the energy consumption and noise of the cooling system.
On the other hand, immersion liquid cooling servers take a different approach. In this system, the server's motherboard, CPU, memory and other high-heat components are completely immersed in the refrigerant. When these components generate heat during operation, the temperature of the refrigerant will rise. Once the temperature of the refrigerant reaches the boiling point set by the system, the refrigerant will undergo a phase change from liquid to gas, absorbing a large amount of heat through this process, thereby achieving effective heat transfer. This technology that uses liquid phase change to directly remove heat is called phase change liquid cooling. Compared with cold plate liquid cooling, immersion liquid cooling technology reduces the thermal resistance in the heat transfer process, provides higher heat transfer efficiency, and becomes an energy-saving and efficient cooling method.
