Abstract

Despite recent improvements in data center cooling efficiency such as hot and cold aisle and air side economizer, air cooling may not have the capacity to cool high end racks such as from IBM's NetBAY42 (150Kw and above). Increasing computer capabilities in data center has resulted in increase in rack power density per square ft as indicated by the latest uptime. The cooling of such high powered servers and corresponding racks poses a significant challenge to thermal engineers.The use of immersion cooling is novel approach for data center cooling. In this study after some modification high powered server is fully immersed in mineral oil which works as a coolant. Various parameters like total server power consumption, temperature of all heat generating components like CPU case and die, VRDS, are measured. The benchmark for this study is conventional air cooling where server power measured at different CPU utilization. Corresponding liquid cooling experiments are done by cases where Junction temperature kept same as air cooling or pumping power is kept the same as that of air cooling. The results are then compared showing that liquid cooling has better promise.
