Abstract:

Under the guidance of the carbon peaking and carbon neutrality goals, it is crucial to reduce the energy consumption of computing and promote “green computing”. Immersion cooling has been widely concerned in recent years due to its outstanding advantages of heat dissipation and energy saving. The premise for data centers to pursue high energy efficiency is to ensure the high reliability and availability of data centers. The security, stability, and sustainable evolution of data centers are more important indicators than energy saving. In order to meet large-scale applications, it is necessary to study and evaluate the key technologies such as reliability and evolution capability of the system architecture. From the perspective of the whole process, this paper sorts out the reliability levels and energy efficiency of different liquid cooling technologies by starting from the overall situation of the data center and IT equipment. Then, it focuses on the analysis on reliability and evolution capability of the single-phase immersion cooling technology. It is expected to provide a reference for the large-scale application and development of the single-phase immersion cooling industry in China’s data center.

Key words: data center, single-phase immersion cooling, reliability, coolant
