摘　　要：现行的太阳能聚光型光伏光热一体化集热器,一般需要占用较大的空间,安装维护不便,难以与我国广大的普通建筑群有效结合。基于此,设计了一种小型Fresnel式聚光集热器,提出了光学效率评价方法,并根据实际应用需求构建了集热器的结构优化设计模型,基于年均光学效率最大化的设计目标,采用数值分析软件MATLAB对其各组件尺寸进行了优化。结合其紧凑的结构,易实现与普通建筑或厂房屋顶的有效结合,并可同时提供电能和热能。The existing concentrating photovoltaic(CPV)solar collectors generally take up a large space,are inconvenient to install and maintain,and are difficult to be effectively combined with the large number of ordinary buildings in China.Based on this,a small Fresnel-type concentrating collector is designed,the optical efficiency evaluation method is proposed,and the structural optimization design model of the collector is constructed according to the actual application requirements,and the dimensions of its components are optimized by using the numerical analysis software MATLAB based on the design objective of maximizing the annual average optical efficiency.Combined with its compact structure,it is easy to be effectively combined with the roofs of ordinary buildings or factories,and can provide both electric energy and thermal energy at the same time.
