Evaluation and Optimization of a Two-Phase Liquid-Immersion Cooling System for Data Centers

An efficient cooling system for data centers can boost the working efficiency of servers and promote energy savings. In this study, a laboratory experiment computational fluid dynamics (CFD) simulation were performed to explore performance two-phase system. The coefficient (COP) partial power usage effectiveness (pPUE) proposed was evaluated under various IT (Information Technology) loads. relationship between interval two submerged their surface temperatures by CFD analysis, minimum intervals that could maintain temperature server surfaces below 85 °C obtained. Experimental results show as increases, COP increases pPUE decreases. one experiment, increased from 19.0 26.7, whereas decreased 1.053 1.037. exergy ranges 12.65% 18.96%, tank side accounts most destruction. are 15 mm 1000 W power, 20 1500 W, more than 30 2000 above. observations conclusions in study be valuable references systems centers.
