摘要

A closed-loop pulsating heat pipe (CLPHP) is a passive and promising heat transfer device used for the thermal management of modern electronic devices. Recent research focuses on the development of more efficient and advanced CLPHPs. Thermal performance of a CLPHP depends on the operating regime, which is influenced by highly coupled operational-geometrical parameters. Among all influencing parameters, number of turns, filling ratio, heat input, and orientation significantly alter the start-up and critical heat flux limitation of a CLPHP. Hence, the aim of the present research is to propose operational regime maps based on these parameters. An experimental setup is developed for three-, six-, and nine-turn water-based CLPHPs. Filling ratio (FR) is set as 25, 35, 50, 65, and 75%. Heat input is kept in the range of 5-200 W. Vertical bottom heating position (0 deg orientation), inclined bottom heating position (45 deg orientation), and horizontal heating position (90 deg orientation) are considered. FR of 50% and nine-turn CLPHPs are observed to perform better with all orientations compared to three- and six-turn CLPHPs. Operating regime of a CLPHP is observed to expand with increase in heat input, FR, and number of turns of a CLPHP.
