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.鉴于其卓越的热传递性能和运行特性，闭式循环脉冲热管（CLPHP）已广泛应用于太阳能热水器、电子冷却、热回收系统、航天技术以及其他不同领域的热管理。闭式循环脉冲热管是一种双相无源热传递装置，涉及相变现象以及由于蒸发器和冷凝器之间压力差而产生的振荡。本研究论文对具有适当所需尺寸的毛细管、蒸发器部分、绝热部分和冷凝器部分的闭式循环脉冲热管进行了实验研究。研究探讨了填充率（25%、35%、50%、65%和75%）和方向（0° - 垂直位置、45° - 斜置位置和90° - 水平位置）对6转闭式循环脉冲热管的热性能的影响，实验中使用水作为工作流体。实验研究过程中还观察到了无脉冲、脉冲和干燥现象。
