Pulsating heat pipes (PHPs) are the new addition to the wickless heat pipe family introduced by Akachi in 1990’s, in last few decades this device acts as a promising source for cooling electronic devices where temperature difference between source and sink is very small. Pulsating heat pipes are highly acceptable devices due to its simple design, light weight feature and small size. Initially the review is focused on mechanism of fluid transport inside the PHPs and number of parameters which effect the working of PHPs is listed. The next half outlines the fundamentals of design and effect of design parameters on Thermal Performance of PHPs. The progresses in design of Critical Diameter, Numbers of Meandering Turns, Working Fluids and Filling Ratio are reviewed in this literature.
