Description
Technical field
The utility model relates to a kind of solar power generation beam condensing unit, specifically a kind of solar energy condensation board.
Background technology
Along with the progress of expanding economy, society, people propose more and more higher requirement to the energy, and seeking new forms of energy becomes the urgent problem that current mankind faces.Solar power generation is not because its safety, clean can threaten the mankind and destroy environment, and it is the optimal energy that inexhaustible, nexhaustible characteristics are described as.But solar energy also has its weak point, and promptly Zhao She Energy distribution density is little, take huge area, and simultaneously, solar energy photovoltaic material costs an arm and a leg, a large amount of use meetings.Therefore concentrating to generate power becomes the development trend of solar power generation.The optically focused of convex lens is too concentrated, can cause the photovoltaic element local overheating, can't use.The hot spot that traditional Fresnel lens is assembled be circular, and the photovoltaic element of the usefulness of generating electricity usually is a rectangle, therefore assemble light can not effectively utilize, efficient is not high, and Fresnel lens manufacturing process complexity, cost are higher.
Summary of the invention
To be solved in the utility model is optically focused problem in the solar energy concentration generating, provides a kind of high-effective concentration, optically focused zone distribution of light evenly and the solar energy condensation board of low cost of manufacture.
The utility model is for solving the problems of the technologies described above, the technical scheme that is provided is: a kind of solar energy condensation board, solar panel is made of a bottom surface and an optically focused plane of refraction, described bottom surface is a smooth plane, the optically focused plane of refraction constitutes by center printing opacity module with around the concentration module that center printing opacity module is arranged in order setting, center printing opacity module is the shape rectangular module all identical with size with concentration module, center printing opacity module is the transmission plane at optically focused plane of refraction center, concentration module is symmetrical arranged around the printing opacity module of center, concentration module inside is provided with a plurality of jagged refracting strips, and each refracting strips is all perpendicular to the central point of the concentration module at its place and the line between the printing opacity module centers point of center.
In the utility model, described zigzag refracting strips, the face of facing center printing opacity module is the inclined-plane of inclination perpendicular to the optically focused plane of refraction back to the face in center printing opacity module.
In the utility model, the surface slope of the refracting strips in the different concentration modules is directly proportional with the distance apart from center printing opacity module centers point.
In the utility model, described refracting strips has identical height.
In the utility model, be provided with dividing plate between each adjacent modules of solar panel.
In the utility model, center printing opacity module is the identical square of size with concentration module.
The beneficial effects of the utility model are: center printing opacity module is that smooth flat can allow light directly pass through, and forms square light piece under it; The refracting strips that is provided with is perpendicular to the concentration module at its place and the line of center printing opacity module centers point, can make sunlight after refracting strips reflects, evenly accumulate under the printing opacity module of center, and because the refracting strips in the same concentration module is parallel to each other, and surface slope is identical, refracted ray is evenly throwed, the shape in optically focused zone is identical with concentration module, is square.Identical with the photovoltaic element shape in the solar power generation, therefore can make photovoltaic element evenly be subjected to light, the local overheating situation can not appear.The quantity of the square modules that the light concentrating times of solar panel equals to be partitioned into, spotlight effect is good.Whole employing modularized design, manufacturing process is simple, has reduced cost.

Embodiment
As shown in Figure 1, a kind of solar energy condensation board, it simultaneously is divided into the identical square modules of a plurality of sizes, in the solar panel 1 RC module center printing opacity module 2 that is the plane printing opacity, all the other modules are to be symmetricly set on center printing opacity module 2 concentration module 3 on every side, be provided with dividing plate 5 between each module, be provided with refracting strips 4 in the concentration module 3, the refracting strips 4 that is arranged in the same concentration module 3 is parallel to each other, and perpendicular to concentration module 3 central points at its place and the line between printing opacity module 2 central points of center.
As shown in Figure 2, the one side of solar panel 1 is a smooth flat, and another side is provided with refracting strips 4.Refracting strips 4 has two surfaces, wherein a Surface Vertical at close solar panel 1 center is in solar panel 1, another surface is an inclined-plane, the refracting strips 4 that is arranged in the same concentration module 3 has identical surface slope, the surface slope of the refracting strips 4 in the different concentration modules 3 is directly proportional with the distance apart from center printing opacity module 2, promptly refracting strips 4 gradients away from center printing opacity module 2 are big, and are little near refracting strips 4 gradients of center printing opacity module 2.Because it is refracting strips 4 has identical height, and is many away from refracting strips 4 numbers in the concentration module 3 of center printing opacity module 2, few near refracting strips 4 numbers in the concentration module 3 of center printing opacity module 2.
Principle of the present utility model is: sunlight enters from the smooth flat of solar panel 1, compiles under the center of solar panel 1 printing opacity module 2 after reflecting in the inside of refracting strips 4.The refracting strips 4 that is arranged in the same concentration module 3 is parallel to each other, and has identical surface slope, so is provided with and can guarantees that the light that same concentration module 3 reflects is parallel to each other, and evenly projects on the photovoltaic element.Refracting strips 4 is perpendicular to concentration module 3 central points at its place and the line between printing opacity module 2 central points of center, be point on the refracting strips 4 and the line between the corresponding points in the center printing opacity module 2 perpendicular to refracting strips 4, can guarantee that the light that enters from a point of concentration module 3 is through focusing on after the refraction under the corresponding points of center printing opacity module 2.Light spot shape through converging in after concentration module 3 refraction under the center printing opacity module 2 is identical with concentration module 3 shapes, the hot spot that all concentration modules 3 converge is overlapped to be radiated on the photovoltaic element that printing opacity module 2 belows, center are provided with, the multiple of optically focused equals the quantity of the square modules that is partitioned on the solar panel 1, can significantly improve the generating efficiency of the photovoltaic element of unit are, for identical energy output, the comparable use saved a large amount of photovoltaic elements before the solar panel, significantly reduces the cost of solar power plant.
