ABSTRACT

In this article, the results obtained from a detailed experimental investigation of the thermal performance of mesh wick heat pipe are presented. The effects of heat input, inclination angle, and the volume of the working fluid on the thermal performance of the heat pipe were investigated. Experimental investigations were carried out over a wide range of heat input (50-150 W), different inclination angles (0°, 15°, 30°, 45°, and 60°), and volumes of the working fluid (20 mL, 25 mL, 30 mL, and 35 mL). The results show that the thermal performance of the heat pipe increases with increase in the heat input until the dryout condition is achieved. The heat pipe achieved the maximum thermal efficiency of 69% at 150 W heat input, 30° inclination angle, and charged with 35 mL of working fluid. The authors highlight the different causes responsible for the enhancement in the thermal performance of the heat pipe.
