摘要

A pump-driven loop heat pipe (PLHP) system was proposed for cooling data centers freely. Based on exergy balance equation of steady flow system the exergy balance models of components for the system were established. The variation and distribution of exergy loss for both system and every single component under three working conditions were compared theoretically and experimentally. The results showed that the largest exergy loss was from the evaporator, over 40%. The next was from the condenser and the pump, about 25%. The exergy loss of the condenser and the evaporator were mainly caused by the heat transfer temperature difference. The exergy loss of the pump was mainly from the deviation of isentropic compression process. The evaporator, the condenser and the pump should be considered in sequence for system thermal performance improvement.
