太阳能收集和传输的研究

The study on collecting and transporting solar energy

对高精度太阳能抛物面镜收集器和大孔径低损耗PMMA／Ag泄漏型空芯光纤进行了设计与研究，安装在收集器上的光电追踪器保证了入射光线聚焦在抛物面轴上，有利于聚焦光斑有效地传输到空芯光纤内。与传统的太阳能利用装置相比较，本装置不需要进行能量转换，因此效率高，结构简单，可以实现聚焦后太阳能的远距离高效传输。

This paper describes a new design and study on highly accurate paraboloidal mirror concentrator and a large bore low-attenuation PMMA-coated silver hollow optical fiber. A photoelectric tracking system mounted on collector has been used to keep the focal point staying on the axes of the paraboloidal mirror. This can efficiently concentrate sunlight into a single hollow optical fiber. Relative to conventional solar energy designs, it needs no energy conversion, thus it is much efficient, simple and easy to handle remote delivery of highly concentrated sunlight.
