Simulation Study on Nanofluid Heat Transfer in Immersion Liquid-Cooled Server

In order to study the application of nanofluids for enhancing heat transfer in field liquid-cooled data centers, a mathematical and physical model servers was established this paper. FC–40 used as server cooling liquid base, simulation studies were conducted on flow five types nanofluid: Cu–FC40, CuO–FC40, Al–FC40, Al2O3–FC40, TiO2–FC40. The results showed that using Al–FC40 medium had best effect. Under same operating conditions, average Nusselt number Nu friction resistance coefficient f nanofluid analyzed, state smallest f. Further analysis influence ‘nanoparticle volume fraction’ α ‘server inlet rate’ u fluid transfer. Our research found an increase acceleration can effectively reduce surface temperature components. As increases, gradually increases generally decreases, but amplitude decrease becomes smoother.
