热管式玻璃真空集热管有效透过率的研究

STUDY ON EFFECTIVE TRANSMISSIVITY OF THE GLASS TUBE FOR A VACUUM COLLECTOR TUBE WITH HEAT PIPE

本文对平行光垂直入射热管式真空集热管时玻璃管的有效透过率τ~*及有效反射率ρ~*进行了理论研究,得到了计算公式,并编制了计算机程序。将计算结果绘制成图,讨论了玻璃的折射率n、消光系数k、玻璃管半径R和壁厚L对τ~*的影响。

In this paper, the equation of effective transmissivity τ and effective reflectivity ρ of the glass tube for a vacuum collector tube with heat pipe normally irradiated by para-lell lights were derived theoretically. The figures were plotted according to the calculation results, and effects of refractive index n, extinction coefficient k, outer radius R and thickness L of the glass tube on τ were discussed.
