The purpose of the present study is (i) to disclose transport phenomena in pipe flow using nanoflud and (ii) to develop a multi heat pipe cooling device and to study the effects of charge ratio and heat flux on its heat transfer performance. The fill charge ratio between fill charge volume of working fluid and internal evaporator section volume were ranged from 30% to 100%. The heat fluxes applied to the evaporator section were changed from 5W/cm2 to 20W/cm2.Heat transfer performance in the circular tube flow is amplified by suspension of nanoparticles in comparison with that of the pure water and Heat transfer enhancement is effected by the occurrence of particle aggregation, i.e., zeta potential of nanoparticles in suspension. The effective thermal conductivity for nanofluid is higher than that for pure water and this trend is the same in the wide range of heat flux.

本研究的目的是（i）揭示使用纳米流体的管流中的传输现象和（ii）开发多热管冷却装置，并研究充液比和热通量对其传热性能的影响。 工质充注量与内部蒸发段容积的充注比为30%~ 100%。 蒸发段的热流密度从5 W/cm ~ 2变化到20 W/cm ~ 2。与纯水相比，纳米颗粒的悬浮增强了圆管流动的传热性能，而颗粒聚集的发生，悬浮液中纳米颗粒的zeta电位。 纳米流体的有效导热系数比纯水的高，并且在较宽的热流密度范围内，这种趋势是相同的。
