Predicting the Performance of Heat Pipe at Different Inclination Angle

This paper focused an experimental study of heat pipe to predict the performance of the heat pipe at different tilt angle. The distilled water is used as a working fluid in this study. The temperature was measured with data acquisition system at variouspositions of heat pipe after steady state. The performance of heat pipe is predicted by the deviation of temperature at different section of heat pipe at different tilt angle and heat input power. Thermal resistance is also estimated to understand the behaviour of heat pipe. It is observed thatbehaviour of heat pipe is very poor at 90 degree inclination compare to other inclination angle. The optimum condition for getting high thermal performance from heat pipe is at 0 degree inclination for low power inputhowever at high power input it is observed at 45 degree inclination angle.
