摘要:

在“双碳”目标引领下,降低计算能耗,推动“绿色计算”十分关键。单相浸没液冷因突出节能优势近年来得到广泛关注。数据中心追求高能效的前提是保证数据中心的高可靠性和高可用性,数据中心的安全性与稳定性以及可持续演进是比节能更重要的指标。为了满足大规模化应用,需要对系统架构的可靠性和演进能力等关键技术进行研究评估。基于全流程的视角,从数据中心和IT设备全局出发,对不同液冷技术架构支持的可靠性等级,能效水平等进行了梳理,重点对单相浸没液冷系统架构的可靠性,未来演进能力进行了重点研究分析。通过研究分析,以期为我国数据中心单相浸没液冷行业的更大规模化应用发展提供参考。

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
