基于新型反射塔底式太阳能集热装置的二次反射器结构原理,采用 Soltrace软件对椭圆面和双曲面的二次反射器进行模拟分析.结果表明：最优椭圆面二次反射器结构参数f/2a的合理范围为0．63~0．72,最优双曲面二次反射器结构参数2a/f的合理范围为0．60~0．75,双曲面结构参数的合理范围大于椭圆面；在相同焦距及相同光学效果下,双曲面二次反射器所需的塔高明显低于椭圆面.因此,应优先选用双曲面二次反射器.
基于新型反射塔底式太暘能集熱裝置的二次反射器結構原理,採用 Soltrace軟件對橢圓麵和雙麯麵的二次反射器進行模擬分析.結果錶明：最優橢圓麵二次反射器結構參數f/2a的閤理範圍為0．63~0．72,最優雙麯麵二次反射器結構參數2a/f的閤理範圍為0．60~0．75,雙麯麵結構參數的閤理範圍大于橢圓麵；在相同焦距及相同光學效果下,雙麯麵二次反射器所需的塔高明顯低于橢圓麵.因此,應優先選用雙麯麵二次反射器.

On the basis of the structural principle of secondary reflector in a new type solar collector in beam-down central receiver system,the Soltrace software was employed to perform numerical simulation on the secondary reflector with ellipsoid and hyperboloid.The results show that:the appropriate range of the optimal structural parameters of the ellipsoid secondary reflector 2a/f was between 0.63 and 0.72;that of the optimal structural parameters of the hyperboloid secondary reflector 2a/f was between 0.6 and 0.75, which was larger.With the same focal length and optical effect,the tower height the hyperboloid secondary reflector required was obviously lower than that of the ellipsoid secondary reflector.Therefore,the hyper-boloid secondary reflector should be chosen first.
