At present, the heat dissipation of computer server chips mainly adopts an air cooling technology, i.e. the air is used for directly cooling the heating components of electronic equipment, and the gaps between the components and the shell are utilized for heat conduction, convection and radiation heat exchange, so that the heat of the heating components is dissipated to the surrounding environment and cooled, and the air cooling technology is generally used in places with low heat flux density of the server, and when the heat flux density of the server is higher than 80w/cm²The problems of high energy consumption, local heat island effect and noise of air cooling are very obvious, and the reliability of the product is further reduced.

The immersed liquid cooling technology is a cooling mode with high efficiency in liquid cooling, and is mainly characterized in that electronic components of a server are immersed in non-conductive liquid, heat is transferred to cooling liquid from heating components, and then the heat is transferred to the external environment by utilizing external fluid circulation or evaporative cooling heat dissipation, so that the effect of efficient cooling is achieved. The immersion type liquid cooling technology can be divided into a single-phase immersion technology and a phase-change immersion technology according to different selected immersion working media. For 10kW equipment, water and air are taken as examples, and if the temperature of the equipment is controlled to 10 ℃, 3250m of air is needed³The volume difference between the two water flows is 275 times. Therefore, air cooling is not the optimal choice, and the liquid cooling technology is far superior to the air cooling technology. Regarding the liquid cooling technology, a great deal of research and practical application mainly stay in the cold plate type liquid cooling server, and the heat dissipation and cooling effects are not ideal.
