Abstract

Heat pipes are widely used for the thermal control of electronic devices due to their capability of heat transport at high rate over considerable distance with small temperature drop. This study investigates the experimental performance of the heat pipe using the combination of copper nanofluids and the different types of aqueous solution of long chain alcohols. An experimental system is set up to measure the temperature distribution of heat pipes along the surface to determine the thermal efficiency and the thermal resistance of different working fluids computed. The working fluids used in this analysis illustrate certain improvement in the metrics over the conventional working fluids, pertaining to the heat transport limitations. The experimental results display higher efficiency and lower thermal resistance of the heat pipe when compared with the conventional working fluids like water.
