中文摘要：
提出了带内循环管的新型重力热管，通过内循环的引入提高了液体的有效提升高度，增大了换热面积；而且在蒸发段实现了降膜蒸发，大大提高了热管的传热传质性能，最终提高了其热传导性能。内循环管的引入也消除了常规重力热管的携带限和沸腾限的约束，提高了热管的工作温度范围。对相同规格的常规重力热管和新型重力热管分别建立数学模型，分析其传热传质性能。结果表明，与常规重力热管比，新型重力热管蒸发段的导热系数和相当导热系数分别提高了11．5-13倍和386-563倍。
英文摘要：
An innovative gravity heat pipe with internal circulating pipe was developed. The use of internal circulating pipe effectively improved the liquid effective climb height, broadened heat transfer area and realized falling film evaporation in evaporator section, which greatly improved heat and mass transfer performance, ultimately improved heat conduction performance of the heat pipe. Also, the internal circulating pipe removed the restriction of both carrying limit and boiling limit on traditional gravity heat pipe and broadened the operation temperature range. The theoretical analysis of both traditional and innovative gravity heat pipes of the same size indicates that the heat transfer coefficient in evaporator section and the equal heat conduction coefficient of the innovative gravity heat pipe were increased by about 11.5-13 times and 386-563 times, respectively.
