Heat transport from source to sink is one of the important aspects served by conventional heat pipes, metallic surface fins and heat exchangers, etc. Miniaturization of electronic components and increased performance capabilities of electronic devices required a compact, efficient heat transfer device unlike conventional heat pipes. Closed-loop pulsating heat pipes serve this purpose. This work is focused on experimental analysis of CLPHP of 2 mm internal diameter and 3.6 mm outer diameter, 5 turns, bottom heating mode and 50% filling ratio for calculation of heat transfer performance. The working fluids used are water, acetone pure fluids and water–acetone (1:1 by volume) binary fluid. The CFD analysis for heat transfer is performed so as to compare the experimental results with CFD results on same geometry. It is observed that CFD results are in close agreement with experimental results. Acetone is found to have better heat transfer performance for CLPHP.
