摘要
以槽式太阳能集热管为研究对象,提出了一种抛物面式集热管。根据集热管边缘角θmax的大小设计出3种不同类型的集热管,利用TracePro和MATLAB软件对抛物面式集热管进行光线模拟和光学聚光比的计算,将计算结果与普通圆柱形集热管相对比,分析抛物面式集热管在光带分布角度以及光学聚光比分布上的性能优势,比较得出性能最优的抛物面式集热管设计。
A parabolic collector tube was proposed by taking trough solar collector as the research object.According to the size of the rim angleθmax,three different types of collector tube were designed.TracePro and MATLAB were used to simulate light and calculate optical concentrating ratio of the parabolic collector tube.Then the results of calculation were compared to that of the ordinary cylindrical collector tube.Furthermore,the advantages of the parabolic collector tube on the distribution angle of the optical band and the optical concentration distribution were analyzed.Finally,the optimal design of the parabolic collector tube was obtained.
