Pulsating heat pipe (PHP) is a passive two phase heat transfer device which does not require a pump or additional power to transport the working fluid from the region of higher temperature or vice versa. A functional PHP test rig is fabricated with well insulated evaporator and condenser. An experimental study of the performance of PHP is carried out with acetone, ethanol and methanol as working fluid. The filling ratios are varied from 40 % - 60 % in steps of 10 % with varying heat input from 4W to 6W in steps of 1W. A comparative study is made and evaluated the performance of PHP in terms of thermal resistance.
