Problems solved by technology

[0002] With the rapid development of microelectronics technology, based on the requirements of miniaturization and integration, the assembly density of chips continues to increase, and the heat flux density of components and equipment servers continues to increase. In this case, once a heat dissipation failure occurs, it will Seriously affect the performance and life of electronic components
[0003] Traditionally, the heat dissipation of computers mainly adopts air-cooled cooling technology, which uses fans to drive air to directly cool heating components, and uses the gaps between equipment components and the shell for heat conduction, convection and radiation heat exchange to realize heat dissipation of heating components. The purpose of heat dissipation and cooling to the surrounding environment, but the bottleneck of air cooling technology is relatively large, and it faces high energy consumption, local heat island effect, noise problems, etc. in large-scale or high-power applications.
[0004] Based on this, immersion liquid cooling technology came into being. By immersing the whole machine or core components in the coolant for cooling, the efficiency is high. However, the current coolant is mostly used for components such as engines. When it is applied to this industry , causing many problems, such as poor thermal conductivity, poor fluidity, etc. In addition, because computers are subjected to low temperatures, it is necessary to monitor the temperature from time to time. Generally, temperature sensors are used to indicate temperature changes, but it involves energy consumption, installation, etc., which is cumbersome and needs to be improved.
