Plastic transmitting type solar concentrator

Abstract

Disclosed is a plastic transmission type solar energy condenser with high efficiency, low cost, large heat power, convenient operation and wide use, comprising spherical or cylindrical fresnel lens lens which are combined of plastic spherical solar panel formed by partitioning mirror surface approach , support, monitoring device and heat absorption device. Mirror surface formed by the spherical solar panel has spherical or cylindrical plane with the same diameter towards sunshine and a series of concentric cyclic surface or that of line towards focus point, condensing lens is fitted with spherical cap-typed support frame, spherical frame is fixed on rack, rack is fitted with diatropisim tracking axis of condenser and diatropisic tracking axis of condenser is fitted with support for condenser with warp direction tracking axis through U-typed support, and at the bottom of rack there is heat energy absorption device and heat absorption medium which are linked to heat energy transfer device. The invention is suitable for energy source use in family as well as industrial energy source use.

Description

Technical field: [0001] The invention relates to the technical field of solar energy utilization, in particular to a plastic transmissive solar concentrator. Background technique: [0002] Energy is an essential substance for human life, and there are many types of energy, such as oil, coal, natural gas, nuclear energy, etc. However, natural energy sources such as oil, coal, and natural gas will always be exhausted one day. Although nuclear energy has high efficiency and long-term use, it requires huge investment. Once an accident occurs, it will cause great harm to human beings. Solar energy is an inexhaustible and inexhaustible natural energy source, which is environmentally friendly and harmless, and has been paid attention to by scientists from various countries in recent years. [0003] Humans have a long history of using solar energy, such as burning plants, coal, oil, natural gas, etc., which is the indirect use of solar energy. Modern technologies that directly uti...

Problems solved by technology

At the end of the 1970s and the beginning of the 1980s, there was a solar cooker fever at home and abroad. People have done a lot of experiments. Most of the reported solar cookers are specular reflective concentrators. The fatal weakness is that the light-receiving area is small, resulting in The heat cannot meet people's daily needs. In addition, the solar cooker can only be operated in the open air. The wind, sand and low temperature make the thermal efficiency of the solar cooker even lower.

Patent 99211497.7 The umbrella-shaped transmissive solar cooker concentrating principle is also the principle of Fresnel prism refraction, but its expression is unclear. The bottom surface of the prism is expressed as a cylinder parallel to the axis of the mirror, rather than a cone that allows all refracted rays to pass through the focal point. Therefore, the light-gathering efficiency is reduced by at least 7%, and its structure is difficult to implement, and its practicability still needs to be explored
