Abstract

The utility model relates to an apparatus used for collecting and converging solar energy, in specific an edge condenser which comprises a plurality of reflection bent plates the cross section of which is in the shape of a round arc. Each reflection bent plate is arranged according to the following fixed method: the round arc of the cross section of each reflection bent plate has a same center; the bottom of the cross section of each reflection bent plate is on a section of inferior arc curve, while the top of the cross section of each reflection bent plate is on a section of superior arc curve. The superior and inferior arc curves also share a same center. A lighting surface of a solar energy transforming apparatus is arranged under each reflection bent plate. The utility model can greatly improve lighting efficiency and usage effect of the solar energy transferring apparatus.

Description

The edge concentrator

Technical field

The utility model relates to a kind of device that is used for the collection and the convergence of solar energy, specifically is a kind of edge concentrator.

Background technology

Existing regular solar conversion equipment (as solar thermal collector, photovoltaic cell etc.), general directly by its daylighting acquisition surface light, its lighting quantity is subjected to the influence of the area and the angle of incidence of light degree on its daylighting surface, area one timing when the daylighting surface, along with reducing of angle of incidence of light degree, lighting quantity will significantly reduce, thereby reduce the result of use of whole device for converting solar energy.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of edge concentrator that can be used with device for converting solar energy such as solar thermal collector, photovoltaic cells is provided, it can be improved the adopting into amount of different incidence angles degree light, strengthen the result of use of device for converting solar energy.

Edge of the present utility model concentrator is that the reflection bent plate of circular arc constitutes by a plurality of cross sectional shapes, each reflects bent plate fixed arrangement in the following manner, the cross section circular arc that is each reflection bent plate has the identical center of circle, the lower end of the cross section circular arc of each reflection bent plate all is positioned on one section following circular arc line, and upper end of the cross section circular arc of each reflection bent plate all is positioned on one section last circular arc line, last circular arc line also has the identical center of circle with following circular arc line, and the daylighting surface of device for converting solar energy is placed in the below of each reflection bent plate.

Described reflection bent plate can adopt linear structure, and promptly the overlooking on the direction of whole device, the vertical outline line of each reflection bent plate is the straight line that multistage is parallel to each other.When adopting the reflection bent plate of this form, a reflection side plate can be set respectively in each rear and front end of reflecting bent plate, the rear and front end of each reflection bent plate is separately fixed on two reflection side plates, between two reflection side plates and the vertical plane that reflects bent plate an outside open included angle is arranged, the big I of included angle is selected between 0 °～50 ° according to the difference of the Position Latitude that uses this device.

Described reflection bent plate also can adopt the circular ring type structure, and promptly the overlooking on the direction of whole device, outline line of each reflection bent plate is a plurality of concentric circles.

Edge of the present utility model concentrator can be installed in various device for converting solar energy (as too can heat collector, photovoltaic cell etc.) the daylighting surface, in use, enter the light of edge concentrator scope, no matter the size of its incident angle, all can and finally project on the daylighting surface of device for converting solar energy through the reflection of diverse location reflection bent plate, thereby can improve the lighting efficiency of device for converting solar energy greatly, strengthen its result of use.
