基于Tracepro光学分析软件,以实验室自行研发的碟式太阳能聚光器-半球形腔式吸热器系统为对象进行三维实体建模,探寻放置腔体穹顶的反射圆锥几何参数(圆锥锥角)对吸热器性能影响规律,同时探讨吸热器采光口距聚光器焦点平面距离L对吸热器性能影响。模拟结果表明:反射圆锥半径为20 mm,锥角α=120°时,半球形腔式吸热器光学性能最优;吸热器采光口距离聚光器焦点前后变化时得出各参数呈正态分布。可为碟式太阳能聚光反射系统的设计和优化提供参考,并为下一步的实验研究提供基础。
Based on the Tracepro optical analysis software, the three-dimensional solid modeling of the disc-shaped solar concentrator-hemispherical cavity heat sink system developed by the laboratory was conducted. The geometric parameters of cone reflection (conical cone angle) On the performance of heat sink law, and at the same time to explore the heat sink from the light collector mouth condenser focal plane distance L on the performance of the heat sink. The simulation results show that the hemispherical cavity heat sink has the best optical performance when the radius of the reflective cone is 20 mm and the cone angle is α = 120 °. The parameters of the hemispherical cavity heat sink are the best when the reflector is changed from front to back. State distribution. It can provide a reference for the design and optimization of the dish solar concentrating and reflecting system and provide the basis for the further experimental research.
