| 摘 要： | 建立了太阳能重力热管的传热模型,分析了其内部传热性能,发现太阳能重力热管的传热性能受太阳辐照度的影响较大,其热管的瞬时效率仅在热管刚开始运行时较高,然后就不断降低。如何通过技术措施保证一个稳定较高的太阳能重力热管瞬时效率,是提高热管传热能力必须解决的关键问题。

| Abstract: | Based on the heat transfer model of the solar gravity heat pipe,we analyzed and found that the heat transfer performance of solar gravity heat pipe comparatively large was influenced by solar irradiance.The instantaneous efficiency of the heat pipe was only higher in the beginning of the heat pipe runtime,and then continued to reduce.So how to ensure a stable and high instantaneous efficiency is the key issues to improve the heat transfer capacity of the heat pipe. |
