Description
Technical Field
The patent relates to a multi-mirror combined condensing device, in particular to a condensing device with a cylindrical convex lens and multiple-surface combined.
Background
The light collection is an effective means for improving the heat collection efficiency and the photovoltaic efficiency, and a common light collection lens can focus a focus on an axial projection surface of the lens, so that the light collection lens, the heat collection surface and the photovoltaic panel are in a parallel plane relation, namely, only one surface of the heat collection body can face the light collection lens, the structural relation between the heat collection body and the light collection lens is limited, the structure is simplified, and the light collection or heat collection efficiency is low. The multi-face combination light gathering energy can lead the natural illumination angle and the illumination collecting device to generate multi-form combination and conversion, and the plane collection can be changed to the vertical collection, so that the small plane can generate a larger illumination collecting surface. The focused light has higher thermal conversion efficiency, higher photovoltaic conversion efficiency and higher output voltage. It is well known that solar energy is the only energy source outside the ground which is utilized by human beings at present, is the cleanest green energy source, and can be used for realizing 'carbon peak' and 'carbon neutralization', so that the dependence of the human beings on fossil energy sources is reduced, and the environment for the human beings to survive is effectively protected.
