Thermodynamic Performance Evaluation of Heat Pipe

Abstract

Heat pipe is known as one of the most energy efficient passive heat transfer device with high thermal conductivity. In the present paper, the thermodynamic performance of heat pipe is experimentally evaluated at different operational angles with different mass flow rates of external cooling water at condensing section. It is found that the heat transfer rate is maximum (i.e. 754 W) at the heat pipe orientation of 30°.
