太阳能学报1981年第2期刊载了“混合式聚光集热器性能的理论分析”一文,本文将对其中有关集热管的热损计算提出讨论,以就正于刘鉴民同志和感兴趣的读者。 [1]中所讨论的集热管,采用玻璃管外罩隔热,且环形间隙被抽成真空,故集热管与玻璃管之间的自然对流换热可忽略不计,只需计算集热管与玻璃管之间的辐射换热。 Journal of solar energy in 1981, No. 2 published a “theoretical analysis of hybrid condenser performance,” a text, this article will be on the calculation of the heat pipe heat loss are discussed in order to be positive Comrade Liu Jianmin and interested readers. The heat pipe discussed in [1] is insulated by a glass tube cover, and the annular gap is evacuated, so the natural convection heat transfer between the heat collecting tube and the glass tube is negligible. The heat collecting tube and the glass tube Between the radiation heat transfer.
