摘      要：In this experiment,a four-turn oscillating heat pipe(OHP)is made of copper tube with an inner diameter of 1.3mm,and an outer diameter of 2.5mm.A series of experiments are performed to investigate the startup characteristics of OHP,and the effects of different working fluids(FS-39E microcapsule fluid,pure water,ethanol),different liquid filling rates(40%-80%)on the heat transport capability of OHP in vertical bottom heat *** results show that the startup of OHP is relative with liquid filling rate,thermal driving force and working fluid;and experiences different flow patterns with the increase of heat *** best concentration of FS-39E microcapsule fluid is 1wt%.While FS-39E microcapsule fluid is used as the working fluid,compared with pure water and ethanol,the OHP has a broader working scope;when the liquid filling rate is relatively high,the OHP shows a better performance on the startup and heat transport capability.
