摘　　要：介绍了一种新型多曲面槽式太阳能聚光集热系统的工作原理,在计算机上进行三维建模,利用光学分析软件对该聚光集热系统安装平面型接收器和圆柱型接收器进行光线追迹分析,考察了接收器上的接收光束随入射光束角度的变化情况。通过追迹模拟,直观地再现了聚焦光线的分布、焦线宽度、偏心量和光线传输效率随入射偏角的变化。并对两种接收器类型产生的聚焦结果进行了比较分析,给出定量结果。A new multiple chamber trough solar collector and its working principles are introduced. A 3D computer model supported with optical analysis software is used to analyze the ray tracing of the solar light concentrating system.This investigates the flat receiver and cylindrical receiver respectively as well as determining the relationship between the receiving beam and the incident ray. By light tracing simulation,the distribution,width,eccentric magnitude of the image,and efficiency of the concentrated light varying with the incident angle can be calculated and visualized.Furthermore, the concentration ability of the system with flat receiver and cylindrical receiver is quantitatively analyzed and compared.
