Effect of Design Parameters on Performance of Closed Loop Pulsating Heat Pipe

Abstract

Advancement is taking place in electronic field of engineering and increasing the demand for of smaller and effective heat transfer devices. Several cooling methods are employed to cool the electronic devices. Pulsating heat pipe (PHP) is a passive two-phase heat transfer device for handling moderate to high heat fluxes typically suited for power electronics and similar applications. It usually consists of a small diameter tube, closed end-to-end in a loop, evacuated and then partially filled with a working fluid. Heat transfer is through natural oscillations of the working fluid between the evaporator and condenser sections. In the present work, the experimental studies are carried out on a single loop PHP for the variation of applied heat flux, filling ratio and working fluids. The performance parameters of PHP like thermal resistance and heat transfer coefficient are would be evaluated for the above conditions
