摘　　要：目前单元式水冷多联热管被广泛应用于数据中心的冷却。传统的热力学分析方法计算粗糙,只能间接反映系统的实际运行过程。本文应用有限时间热力学分析方法,真实再现了系统的实际运行过程。针对长沙某电信机房传统的风冷精密空调改造前后的全年能效进行了建模和计算。结果表明全年节能约200万kWh。At present,the unit water-cooled multi connected heat pipe is widely used in data center cooling.The traditional thermodynamic analysis method is rough and can only indirectly reflect the actual operation process of the system.In this paper,the finite time thermodynamic analysis method is used.The real operation process of the system is reproduced.This paper models and calculates the annual energy efficiency of the traditional air-cooled precision air conditioner in a telecommunication room in Changsha.The results show that the annual energy saving is about 2 million kWh.
