Summary

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