Thermal Performance Enhancement of Cylindrical Heat Pipe using Tio2 Nanofluid

Heat pipe has been used as one of the alternative methods to absorb more heat in the cooling systems of electronic devices. An experimental study of heat transfer execution of heat pipe for examining the effect of different layers screen mesh wick and Titanium Oxide (TiO2 ) nano fluid as operating fluid was conducted. Three heat pipes were fabricated. In this heat pipes, with multilayer of screen mesh wick are used to improve capillary activity of working liquid. Heat pipes having 12.5 mm diameter and 300 mm total length are selected. The heat pipes are tested with water and TiO2 as working fluid for different heat inputs i.e. 50 W, 100 W, 150 W, and 200 W. In this work, considered base fluid as De-ionized water and adding different concentrations of Titanium Oxide (TiO2 ) for minimizing the thermal resistance and increasing the thermal conductivity of a screen mesh wick heat pipe. Heat pipe material was copper (Cu), mesh material also copper, and testing heat pipe was done with different concentrations of nanofluid.
