Effect of Al₂O₃-Water Nanofluid on the Heat Performance of Gravity-Assisted Heat Pipe

Abstract:

The aim of this paper is to investigate the effect of nanofluid on the heat transfer performance of heat pipe and to examine the difference of the thermal conductivity between pure water heat pipes and nanofluid heat pipes. In our experiments, Al₂O₃-water nanofluid and pure water were used as working fluids respectively in gravity-assisted heat pipes. Effects of filling ratio and heating temperature on the thermal performance of heat pipe were investigated. The thermal resistance of heat pipe was analyzed. Our results showed that nanofluid can significantly increase the heat transfer coefficient and enhance the thermal performance of heat pipe.
