Abstract
Increase of power consumption in data centers due to the development of ICT technology has become a problem in recent years. Reducing the air conditioning power consumption is significant important for maintaining the function of data centers while decreasing the total power consumption. In this study, we developed a heat transfer module to remove the heat exhausted from a High-Powered Server Rack. The heat transfer module with multi-stage heat exchangers can transport more than 50% of the exhaust heat from servers generating 20 kW/rack.
