  As a mature thermal technology, liquid cooling has been widely used in industrial applications, such as the automobiles, aircraft engines and servers. The application of liquid cooling technology to the server field is not because air cooling has been developed to the end, but because the heat dissipation rate of liquid is much greater than that of air, so liquid cooling radiators often have a good heat dissipation effect, and the noise can be well controlled. Due to various advantages in heat dissipation efficiency and quietness, liquid cooling is more and more popular in server heat dissipation, this situation is attributable to the great progress in the safety and stability of liquid-cooling.

  A typical water cooling system must have the following components: cold plate, fluid medium, water pump, water tube and water tank or heat exchanger. A cold plate is a metal block with water channels inside, made of copper or aluminum, that is in contact with the CPU and will absorb heat from the CPU. The fluid medium flows in the circulating pipeline by the action of the pump. If the liquid is water, it is what we commonly call the water cooling system. The liquid that has absorbed the CPU heat will flow away from the cold plate on the CPU, and the new low temperature liquid will continue to absorb the CPU heat. The water pipe connects the water pump, the cold plate and the water tank, and its function is to allow the fluid to circulate in a closed channel without leakage, so that the liquid cooling system can work normally. The water tank is used to store the fluid, and the heat exchanger is a device similar to a heat sink. The water transfers heat to the heat sink with a large surface area, and the fan on the heat sink removes the heat from the incoming air.

  The essence of water cooling and air cooling is the same, except that water cooling uses fluid to transport the heat of the CPU from the cold plate to the heat exchanger and then dissipate it, instead of the metal or heat pipe for air cooling. The heat exchanger part is almost a replica of the air-cooled radiator. There are two biggest features of the water cooling system: balanced CPU heat and low noise work. Due to the large specific heat capacity of water, it can absorb a large amount of heat and keep the temperature from changing significantly. The temperature of the CPU in the water cooling system can be well controlled, and sudden operations will not cause a large instantaneous change in the internal temperature of the CPU. Due to the large surface area of the heat exchanger, only a low-speed fan is needed to dissipate heat. Therefore, most of the water cooling is equipped with a low-speed fan. In addition, the working noise of the water pump is generally not obvious. , so that the overall cooling system is very quiet compared with the air cooling system.

  Due to the increasing integration of servers, and the power is much higher, the liquid cooling solution is more and more important for the server cabinet, liquid cooling heat sink system can solve the high power server thermal issues and offer low noise operation.
