表面浸润程度对脉动热管传热性能的影响
Effect of surface wettability on heat transfer performance of oscillating heat pipe
摘要
Abstract
Experiments were performed to understand the influence of surface wettability on heat transfer performance of an oscillating heat pipe (OHP),the alkali assistant surface oxidation technique was used to fabricate the surfaces.The surfaces with different wettability were obtained by control the concentration of the reaction solution of sodium hydroxide and ammonium persulfate.Different OHPs were obtained with the surface contact angles(CA) of 0°、33.9°、55.7°、84.3°,respectively.The effect of different degrees of surface wettability on heat transfer performance of oscillating heat pipe was investigated experimentally.The results show that the oscillating frequency and amplitude of the working fluid in the OHP increases as the CA increases.The thermal resistance and temperature difference of OHP decreases as the CA increases.Therefore,heat transfer performance of the OHP was enhanced as the CA increases.关键词
