实验研究了绝热段导热对振荡热管振荡运动和传热性能的影响。构建了两个闭环6圈OHP;一个具有用于蒸发器和冷凝器部分的单独铜块（分离块设计），另一个使用用于蒸发器、绝热和冷凝器部分的单个连续铜块（连续块设计）。结果表明，热管中蒸发器壁面直接向绝热段和绝热段向冷凝段的热传导，将减小蒸发器、绝热段和冷凝段温度的振荡幅度。还发现，除了更高水平的温度均匀性之外，连续块设计比没有通过绝热段传导的热管具有更好的传热性能。Copyright © 2011 by ASME
The effect of heat conduction through the adiabatic section on the oscillating motion and heat transfer performance in an oscillating heat pipe (OHP) was investigated experimentally. Two, closed loop, 6-turn OHPs were constructed; one with a separate copper block for the evaporator and condenser sections (split block design) and one using a single continuous copper block for the evaporator, adiabatic, and condenser sections (continuous block design). The results show that the presence of heat conduction directly from the evaporator wall to the adiabatic section and from the adiabatic section to the condenser of a heat pipe will reduce the oscillating amplitude of the evaporator, adiabatic, and condenser temperatures. It was also found that in addition to a higher level of temperature uniformity, the continuous block design results in better heat transfer performance than a heat pipe without conduction through the adiabatic section.Copyright © 2011 by ASME
