摘要
固定光口聚光太阳能系统具有宽带集热温度、无需跟踪装置、无机械运动、易于集成构建、运行状态稳定等优点,因此针对圆形吸收体太阳能复合抛物聚光器(CPC)关键部件面形结构进行了研究。理论构建了圆形吸收体CPC面形结构模型,并获得其解析解。运用光学设计软件TracePro验证所构建理论模型的光学特性。利用圆形吸收体CPC面形光学特性,构建了CPC耦合太阳能集热系统,并建立其光学特性计算方法。针对所构建系统的光学特性进行了数值计算,结果表明所构建系统的采光量较真空管太阳能集热系统有所提高,平均提高比例为34.57%。
The fixed solar concentrating system exhibits such advantages as wide heat-collecting temperature band,no tracking device,no mechanical movement,easy integration,and stable operation.Therefore,we study the critical component surface shape structure of the solar compound parabolic concentrators（CPC）with circular absorber.A theoretical model of surface shape structure of CPC with circular absorber is established and the analytic solution of the model is obtained.The optical characteristics of the theoretical model is validated by the optical design software TracePro.Meanwhile,a novel solar collector system with CPC is designed,and the calculation method for optical characteristics is established by the optical characteristics of surface shape of CPC with circular absorber.The numerical calculation is conducted by the optical characteristics of the designed system.The results show that the solar radiation collected by the solar collector with CPC is higher than that of the solar collector with evacuated tubes,and the average ratio is 34.57%.
