Heat generation of datacenters becomes larger and larger because of the improvement ofoperational performance of equipment and the expansion of datacenter scale. Two-phase closedloopthermosyphon system as a new type of cooling system, which has a large cooling capacity, hasgotten a widespread attention. This paper investigates experimentally heat transfer performance ofa closed-loop thermosyphon system by testing under different mass concentrations, heating andcooling scenarios. The system, filled with microencapsulated phase change material suspension(MPCMS), contains heating, cooling and adiabatic sections. The result shows that the convectiveheat transfer coefficient at the heating section inlet with 0.5% MPCMS is twice as much as that ofbase fluid. Hence, a closed-loop thermosyphon system with MPCMS is an effective scheme toenhance the performance of the cooling system.
