Abstract

This papers focuses on experimental analysis of novel Triple Fluid Heat Exchanger (TFHEX) to manage heat from hybrid cooled servers. TFHEX is a finned double tubed heat exchanger that consists of two types of liquid (hot water and warm water) and one gas (hot air). The hot air flows through the fins and the hot water flows through the inner tube. The cooling water that flows through the annular tube removes heat from both hot air and hot water. The prototype model of TFHEX is tested in wind tunnel at different heat load. The heat load is varied by varying the flow rate at a given inlet fluid temperature. The overall performance of the heat exchanger is presented in terms of heat transfer efficiency over the flow rate. The experimental results were also compared with analytical results. While there is some deviation between analytical and experimental results, the results promises that TFHEX can dissipate heat from different fluids at various ratio which necessary customization and this heat exchanger suitable for high ambient data center application.

新型混合冷却三流体换热器的实验分析

本文主要对新型三元流体换热器(TFHEX)进行了实验分析，以管理混合冷却服务器的热量。TFHEX是一种翅片双管换热器，由两种液体(热水和温水)和一种气体(热空气)组成。热空气流经翅片，热水流经内管。流经环形管的冷却水从热空气和热水中去除热量。在风洞中对TFHEX原型模型进行了不同热负荷下的试验。在给定的进口流体温度下，通过改变流量来改变热负荷。热交换器的整体性能表现为传热效率高于流量。并将实验结果与分析结果进行了比较。虽然分析结果与实验结果之间存在一定的偏差，但结果表明，TFHEX可以以不同的比例从不同的流体中散热，这需要定制，并且该换热器适合高环境数据中心应用。
