... part of the proposed system as a complete unit is studied in Ref. [ 31 ], while a separate study focuses on the evaporator of the cooling system [ 32 ]. The working fluid chosen is a low-pressure and environmentally friendly refrigerant, namely, R1233zd(E). The refrigerant flows in a thermosyphon-based...

...-coupled technique where the servers are air-cooled, and the air in turn is cooled within the rack enclosure using an air-to-refrigerant heat exchanger. The refrigerant passively circulates in a loop as a thermosyphon, making the system self-sustaining during startup and shutdown, self-regulating under...

...R. Khalid; E. Youssef; R. L. Amalfi; A. Ortega; A. P. Wemhoff A thermosyphon-based modular cooling approach offers an energy efficient cooling solution with an increased potential for waste heat recovery. Central to the cooling system is an air-refrigerant finned tube heat exchanger (HX), where air...

... immersion cooling with fluorocarbons have shown the effectiveness of boiling enhancement structures in lowering boiling incipience, raising the critical heat flux, and reducing evaporator size. Two-phase thermosyphons are an alternative to liquid immersion cooling, where phase change liquid cooling can...
