In this study, a two-phase liquid-immersion cooling system was developed for ICT (Information communication technology equipment) cooling. The PUE energy efficiency of the two-phase cooling system was evaluated under various IT loads, and the annual PUE was calculated dependent on the meteorological parameters in Shanghai. Then, exergy analysis of the two-phase cooling system was taken based on the second law of thermodynamics. The observations and conclusions in this study can be valuable references for the study of cooling systems in data centers.
