Frontiers in Heat and Mass Transfer (FHMT) 13 - 24 (2019)

In the present paper, data center energy conservation systems based on the heat pipe heat exchanger (HPHE) pre-cooler to downsize the chiller capacity and working time has proposed and discussed. The proposed system utilizes thermal diode character of heat pipe to transfer waste heat from source (pre-cooler coolant) to ambient and have been analyzed as per metrological conditions in New York. HPHE Pre cooler with 118 heat pipes and designed for 30 °C ambient temperature has been designed to effectively dissipate 30 kW or more datacenter heat throughout the year. The payback period of the HPHE Pre cooler is around 2.8 years. Proposed heat pipe based system utilize natural ambient cold energy and therefore there is no running cost and no greenhouse gas emissions.
