建立了铜管脉动热管实验台,进行了实验研究.分析了在水冷的条件下,充液率、工质、倾斜角等因素对脉动热管传热性能的影响,结果发现,热阻随着充液率的增加而增大;选用蒸馏水、无水乙醇以及丙酮为工质时,在相同条件下,丙酮热阻最低;不同倾斜角的实验中垂直底加热时脉动热管热阻最低.
An experimental system was set up for a copper PHP.The influences of filling ratio,working fluid and inclined angle are studied carefully.The results indicate that the thermal resistance of the PHP increases with filling ratio.The water.ethanol and acetone are selected as working fluids in this research.The thermal resistance of acetone iS the lowest in the identical condition.The thermal resistance of the PHP in vertical bottom heat iS the 10west in allincline angles.
