Pulsating Heat Pipes (PHPs) have high heat spreading performance and are capable of removing higher heat fluxes. OHPs have superior performance compared to traditional heat pipes and can be used to solve the future electronic cooling problems. Among the novel methods for thermal management of the high heat transfer rate found in microelectronic devices, Pulsating Heat Pipes are the most effective heat removal device. Experimental tests are one of the more popular ways to determine the thermal performance of pulsating heat pipe.
Experimental method was conducted to study the heat transfer and other parameter like temperature distribution, thermal resistance in pulsating heat pipe. In experimental method, heat is applied at constant temperature and heat transfer rate is obtained. This procedure is repeated for different temperature for a particular feeling ratio. Then procedure is repeated for four different feeling ratios like 60%, 70%, 75% and 80%. Experimental set up is consists of 5 turn and acetone is used as a working fluid. The best results are obtained at 75% F.R.
