复合抛物面聚光器(CPC)光学分析研究

The optical performance of Compound Parabolic Concentrators(CPC)

阐述了复合抛物面聚光器(CPC)的设计原理和光学原理,简单介绍了复合抛物面聚光器(CPC)与不同接收器的结合形式。主要介绍了平板型CPC和圆管型CPC的设计方法和相关量的计算公式的推导结果最后主要说明了截取比在CPC系统中对系统效率和系统的经济性的影响,认为合适的截取比可增加CPC的利用率并且可大大的节省材料,对CPC的推广应用很有利。

The paper expounds the design technique and optical performance of the compound parabolic concentrators（CPC） and introduces the different CPC types combined with different absorbers. The design method of flat type and tubular absorber CPC is introduced and the calculation process about some of their characteristic is listed. The truncation is also detailedly discussed. It is proved that appropriate truncation can improve the using of the CPC and reduce the use of material, it is propitious to develop the CPC.
