摘　　要：提出新V形CPC方法,并建立了曲线方程模型,从相对聚光比和缝隙效率上对该方法进行分析,利用光学软件Tracepro运用光线追迹的方法对缝隙的相关问题进行模拟,分析各种缝隙处理方式所具有的优缺点以及缝隙损失的计算公式,总结出如何根据缝隙的大小来选择缝隙的处理方式以及新Ⅴ形法具有良好的应用价值。A new model with new V-shaped profile at the bottom of the reflector for CPC with tubular absorbers was proposed, and the relative concentrating ratio and gap efficiencies of the model were discussed, then the modes were simulated with the method of ray tracing by Tracepro software, and the advantages and disadvantages of these models and the formulas for calculating the gap losses were analyzed, Finally, how to select the model of CPC in accordance with the size of the gap was concluded. The CPC with new V-shaped profile will have a good prospect.
