提出一种新型的分段式槽式太阳能聚光器,通过在平面框架上放置同焦线的多块抛物面反射镜面,将光线聚集于焦线处,使用平板型集热器或圆柱型集热器作为接收体,用于太阳能聚光光热利用。该聚光器由于采用分段式的抛物反射镜,因此相比传统槽式聚光器具有较小的风阻,较低的镜面高度,并同时可达到较高的聚光倍数。根据几何光学原理给出确定每块抛物镜面尺寸及位置的曲线方程,并根据各器件实测的光学性质对聚光器进行理论分析计算,结果表明该聚光器具有较高的集热效率。
A new type of trough-type solar concentrator is proposed. By placing a plurality of parabolic reflecting mirrors with the same focal line on the plane frame, the light is collected at the focal line. A flat-type collector or a cylindrical collector As a receiver, used for solar concentrating solar thermal utilization. Due to its segmented parabolic reflector, this concentrator has lower wind resistance, lower mirror height and higher focusing factor than traditional trough concentrators. According to the principle of geometrical optics, the curve equation for determining the size and position of each parabolic mirror is given. According to the measured optical properties of each device, the condenser is theoretically analyzed and calculated. The results show that the condenser has a high heat collection efficiency.
