摘要 以线性聚光光伏接收器为研究对象,以有效聚光率C=60、光强分布为正太分布为实例,研究了聚光不均匀时接收器温度分布和各材料层(包括电池层、焊锡层和绝缘层)应力应变规律。同时,为了消除光强非均匀分布对接收器性能的负面影响,对接收器结构进行了优化。结果表明,增加焊锡层厚度能有效降低材料Von Mises应力,同时通过适当增大散热器换热系数为代价,最终能有效消除因光强不均匀对脆弱焊锡层造成的损伤隐患,使接收器安全正常工作,达到性能优化的目的。 The effects of non-uniform illumination on the temperature and stress-strain profiles of the concentrator receiver were studied with a Gauss illumination for a linear concentrating photovoltaic system.The results show that the effects of non-uniform illumination increase the von Mises stress and may cause the solder layer to be damaged.By optimizing the structure of receiver,this negative effect can be cleared up and the receiver can work safely again.
