Groove-type compound parabolic concentrating power generation component

Abstract

The invention relates to a groove-type compound parabolic concentrating power generation component, and belongs to the field of solar concentrating power generation technology application. The groove-type compound parabolic concentrating power generation component comprises a groove-type compound parabolic reflecting surface, a vertical reflecting surface, a total reflection transparent film, a photovoltaic cell, a heat dissipation support plate, heat dissipation fins, a fixing bottom plate and keel buckles, wherein the groove-type compound parabolic reflecting surface is formed by horizontally moving a compound parabola along a symmetric axis. The parabolic total reflection transparent film with a thin upper portion and a thick lower portion is attached on a parabolic portion, a photovoltaic component is horizontally placed above a focus of a parabolic surface, light can be collected on the photovoltaic component for concentrating power generation when sunlight enters the groove-type compound parabolic reflecting surface, the concentrating angle and the incident drift angle of a concentrator can be enlarged by the total reflection transparent film, the heat dissipation support plate and the heat dissipation fins are mounted at the bottom of the component, hot air generated by the photovoltaic component in power generation is collected to a building energy storage device by the aid of the 'chimney effect' and then is used, the whole device is connected with an inclined slope roof through the fixing bottom plate and the keel buckles, and a semicircular drainage channel has an automatic drainage function.

Description

technical field [0001] The invention relates to a compound parabolic concentrating power generation component, in particular to a compound parabolic concentrating power generation component for building photovoltaic integration, which belongs to the application field of solar concentrating power generation technology. Background technique [0002] At present, building energy consumption is close to 1 / 3 of the total energy consumption of the whole society, and with economic growth, building energy consumption will continue to increase. Accelerating the large-scale application of renewable energy in the building field is one of the effective measures to reduce building energy consumption and adjust the structure of building energy consumption. This application is called building photovoltaic integration. With its unique characteristics, solar photovoltaic power generation technology can provide electricity or heat for multi-energy complementary building energy systems. How to...

Problems solved by technology

[0003] The compound parabolic concentrator appeared in the 1970s. It is composed of multiple parabolic concentrating mirrors. It does not need to track the sun. At most, it only needs to make small adjustments with the seasons. Disadvantages of placing the concentrating angle too small; the traditional trough parabolic concentrator has the problem of large dispersion of light collected by the light outlet due to non-imaging, and in addition, the retroreflection of light in the parabolic concentrator will also cause shadow problems , will lead to low effective utilization of solar energy
