摘要
由空气夹层和透明蜂窝组成的复合透明蜂窝具有优异的隔热性能。就空气夹层厚度对复合透明蜂窝热损的影响作了理论分析和实验研究，证明空气夹层的存在可大幅度降低集热器的热损。由于空气夹层的两侧具有较大温差，故可使透明蜂窝的工作温度降低，这对延长蜂窝材料的使用寿命有利。
he compound honeycomb consisting of the honeycomb and an air layer has excellent insulation characteristics. In this paper a theoretical and experimental research on effects of the air layer in compound honeycomb on the heat loss is carried out.For the numerical calculation. the radiation-conduction coupling model is used. The heat loss is measured by use of the heat flow meters with the static state technique. The agreement of the analytical and experimental results is good. It is shown that the air layer can significantly decrease the collectors heat loss.
