摘要
数据中心这一“新基建”的冷却节能技术日益受到关注，以近年来的研究热点——浸没液冷技术为研究对象，从数据中心相关器件浸没液冷装置的型式与部件及传热原理相关分析方面进行了回顾与评述。单相浸没液冷装置的主要部件涉及腔体和二次冷却循环系统，与之相关的传热分析则包括无量纲准则数Nu数、对流传热热阻以及Re数对传热效果的影响等；双相浸没液冷装置型式较为多样化，但受到冷却液沸腾相变的影响一般需要设置控压部件，此外双相浸没液冷相关的传热分析则主要涉及总体传热系数和临界热流密度的计算。从工程应用角度，单相浸没液冷技术在服务器级的冷却方面应用较为成熟，而双相浸没液冷技术的早期研究主要集中在电子元器件级别，服务器级双相浸没液冷技术在综合传热分析和系统控制等方面仍有较大提升空间。
Abstract
The cooling and energy-saving technology of data center
a "new infrastructure"
has attracted more and more attention. Takes the research hotspot-immersion liquid cooling technology in recent years as the research object
and reviews and comments from the related analysis of the types and components of immersion liquid cooling devices and heat transfer principle of relevant devices in data center. The main components of single-phase submerged liquid cooling device involve cavity and secondary cooling cycle system. The related heat transfer analysis includes dimensionless criterion number Nu
convective heat transfer resistance and the influence of Re number on heat transfer effect. The types of two-phase immersion liquid cooling devices are more diversified
but due to the influence of coolant boiling phase change
it is generally necessary to set pressure control components. In addition
the heat transfer analysis related to two-phase immersion liquid cooling mainly involves the calculation of overall heat transfer coefficient and critical heat flux. From the perspective of engineering application
the application of single-phase immersion liquid cooling technology in server level cooling is relatively mature
while the early research of two-phase immersion liquid cooling technology mainly focuses on the level of electronic components. The server level two-phase immersion liquid cooling technology still has great room for improvement in comprehensive heat transfer analysis and system control.
