1. Liquid cooling
Liquid-cooled heat dissipation takes the heat of the radiator through the forced circulation of the liquid under the drive of the pump. Compared with air cooling, it has the advantages of quietness, stable cooling, little dependence on the environment and so on. The price of liquid cooling is relatively high, and the installation is relatively troublesome. At the same time, install as much as possible according to the instructions in the manual to obtain the best heat dissipation effect. For cost and ease of use, liquid-cooled heat dissipation usually uses water as the heat-conducting liquid, so liquid-cooled radiators are often referred to as water-cooled radiators.
2. Heat pipe
The heat pipe belongs to a heat transfer element, which makes full use of the heat conduction principle and the rapid heat transfer properties of the refrigerant, and transfers heat through the evaporation and condensation of the liquid in the fully enclosed vacuum tube. It has extremely high thermal conductivity and good isothermal The heat transfer area on both sides of the cold and hot can be arbitrarily changed, long-distance heat transfer, temperature control, etc., and the heat exchanger composed of heat pipes has high heat transfer efficiency, compact structure, and small fluid resistance loss. advantage. Its thermal conductivity far exceeds that of any known metal.
