An experimental data analysis of close loop pulsating heat pipe
Due to effective heat transfer capabilities and operational characteristics, Closed Loop Pulsating Heat Pipe (CLPHP) has been used in many fields like solar water heater, electronic cooling, heat recovery system, space technology and other different areas for thermal management. CLPHP is a two-phase passive heat transfer device. It involves phase-change phenomena and oscillations generated due to the pressure difference between evaporator and condenser. The present research paper presents the experimental investigations on CLPHP having the appropriate required dimensions of capillary tube, evaporator section, adiabatic section and condenser section. The effect of filling ratio (25%, 35%, 50%, 65% and 75%) and orientations (0° -vertical Position, 45° -Inclined Position and 90° -Horizontal Position) on the thermal performance of 6-Turn CLPHP has been investigated with water as working fluid. No pulsation, pulsations and dry out phenomena are also observed during experimental investigations.
Steps to reproduce
The data have been collected with the help of CLPHP setup equipped with Temperature Scanner, E-Scan Software and Heat Control Panel. The temperature data are collected for the evaporator and condenser section when the steady state has been reached.
