Abstract
In recent years heat pipes technology have been widely used in high performance air-cooled heat sinks for cooling electronic equipments. The objective of this paper is to conduct a comparative study on heat pipe performance with different working fluids subjected to different orientations. The working fluids chosen for the study were water and ethanol and the material of the heat pipes is copper with the screen mesh as a wick structure. The experimental results show that the heat transported by the heat pipes of water working fluid are considerably more than that of the heat pipes of ethanol working fluid.
