摘　　要：针对内聚光CPC热管式真空集热管,根据其结构建立详细完整的光学效率模型,采用光学追迹、几何光学分析等方法对模型中的各项参数(几何光学效率、透射比、反射比、吸收比等)进行分析研究。在此基础上,针对所研制的集热管构建出以太阳辐照强度、太阳光入射角为参变量的光学效率模型,并根据计算的数据结果对集热管进行相关分析。所建立的模型可为各种集热器的光学效率分析提供参考。A detailed model of the optical efficiency for heat pipe evacuated tubular solar collector with inner CPC was built in the paper, the parameters of the model ware analyzed, such as geometrical optics efficiency, transmission rate, reflectance rate and absorption rate, with methods of optical tracking and geometrical optics. Based on the model, the optical efficiency of the designed CPC was calculated and analyzed. The models could serve as a reference for optical analysis of solar collector.
