Research on Flat-tube Heat Exchanger with Parallel Micro Channel Groups Applied for Telecommunication Room

本文针对通信机房空调设备能耗高的问题,将新型平行微孔群扁管换热器和传统的溶液循环系统相结合,制成了机房专用换热装置。使用该装置可以将室外自然冷源引入机房,以减小空调设备运行时间,大幅降低能耗。本研究采用现场实测和数值模拟2种方法对新型换热装置的性能进行了研究,研究表明:该装置换热性能优越,且成本低、体积小、质量轻,可以很好地解决机房节能降耗的问题。

In view of the high energy consumption problem of air-conditioning equipment in telecommunication room,a new type of heat transfer system was introduced ,which was composed of the flat-tube heat exchanger with parallel micro channel groups and the traditional solution system. Through bringing outdoor natural cold source into the room, the running time of air-conditioning equipment could be reduced significantly, therewith the energy consumption. In this paper, the performance of this new type of heat exchange equipment was researched through field measurement and numerical simulation. It was indicated that the heat exchanger was of low cost, small size and light weight ,which could save the energy consumption of telecommunication room greatly.
