Solar energy condensation board

Abstract

The invention discloses a solar panel. The solar panel is provided with a strip plate body manufactured by a transparent material with a length which can be infinitely extended. The upper surface of the plate body is a plane; the lower surface thereof is formed by a plurality of same curves which are symmetrically arranged along the middle line of a length direction and are connected in sequence;the lower part of the plate body is provided with a plurality of reflection boards which are symmetrically arranged along the middle line of the length direction, oblique and mutually parallel; the lower parts of the reflection boards are provided with basic boards; the upper surfaces of the basic boards are two symmetrical paraboloids of confocal lines; the two paraboloids are light reflective surfaces which form an empty cavity with the lower surface of the plat body; the focal line A of the paraboloid is arranged on the symmetrical surface of the two paraboloids in the empty cavity; and the area between the focal line A and the crossing line of the two paraboloids is a focal region B; light conversion tubes are arranged in the focal region and neighboring regions; the two ends of the solar panel are provided with end covers used for sealing. The solar panel can assemble beams with high density, is low in cost, and is convenient for installation, use and maintenance.

Description

【Technical field】 [0001] The invention relates to the field of optical technology, in particular to a solar concentrating panel that deflects light and gathers it with confocal double parabola reflection. 【Background technique】 [0002] As everyone knows, solar energy is inexhaustible, but people have not yet been able to use it on a large scale. With the reduction of fossil energy such as coal, oil, and natural gas and the continuous rise in price, it has become more and more important for humans to directly obtain energy from solar energy. At present, various solar energy utilization devices have been used, such as photoelectric conversion and photothermal conversion devices. Ordinary light-to-heat conversion equipment is typically equipped with a light-energy conversion tube coated with light-absorbing and converted into heat energy in each of multiple glass tubes. The density is small, so its heat collection efficiency is low, and the cost of solar energy utilization i...

AI Technical Summary

Problems solved by technology

Ordinary light-to-heat conversion equipment is typically equipped with a light-energy conversion tube coated with light-absorbing and converted into heat energy in each of multiple glass tubes. The density is small, so its heat collection efficiency is low, and the cost of solar energy utilization is high; also because of its large heat dissipation surface, it cannot obtain higher temperature

In addition, devices that use parabolic focusing to collect light energy are widely used in the prior art, which cannot be made into a plate-shaped device, which is bulky and expensive
