Three-dimensional two-stage solar light collector

文章介绍两级式集光器的集光原理和设计理论 ,概述三维两级式太阳光集光器的国际研究现状和发展趋势。通过理论分析 ,将各种文献中有关三维两级式太阳光集光器总集光率的不同表述统一为一个公式 ,并以此为基础 ,探寻提高三维两级式太阳光集光器总集光率的有效途径和方法 ,为太阳能的有效利用提供理论依据。

In this paper, the law and design theory of three-dimensional(3-D) two-stage solar collector is introduced, it also sums up the development process and present situation of various parts made up the system. The total geometric solar radiation concentration of an ideal 3-D two-stage concentrator is accurately expressed in an explicit way. The analysis and discussion have been made for its research and application with 3-D two-stage solar collector in future.
