Abstract

This paper presents an experimental investigation of thermal characteristics of heat pipe (length of 400 mm and diameterof ¼ ̋) with working fluid aseton. The filling ratio was controlled at 80 %. The effect of heat input and inclination of heatpipe on the thermal characteristics of the heat pipe had been studied with variations of (3-6 W) and (0-90°), respectively.The result showed that the high heat input and inclination resulted to the increase of thermal performance of heat pipe

Abstract

Heat pipe is a simple equipment which has a very high thermal conductivity. In a large capacity of heat pipes can transfer the heat efficiently in a wide variety of temperatures without additional energy. The experiment is used copper pipe with a length of 400 mm and diameter 9.525 mm using acetone as working fluid. Screen mesh wick was used by screen 150 mesh. The experimental method is carried out to obtain the characteristics of heat pipe in form of axial temperature distribution, thermal resistance and heat transfer coefficient with filling ratio 60% (of the evaporator volume) at different orientations. The lowest thermal resistance and the highest heat transfer coefficient was occurred in a vertical position at 4.30 °C/Watt and 195.50 W/m2°C respectively. From the three orientations of heat pipes, vertical position indicated the decrease due to temperature difference between evaporator and condensor and the smallest thermal resistance in all heat input.
