A kind of reflection energy collecting plate
Technical field
The present invention relates to collector for solar radiation, especially a kind of reflection energy collecting plate.
Background technology
Known reflection energy collecting plate is for the device of collecting solar radiation, solar radiation is gathered a bit or a zone forms heat by the photo-thermal conversion to conversion and collects utilization by the reflective face with radian.In order effectively to utilize solar radiation, usually it is larger the reflector design of reflection energy collecting plate need to be got size, thereby improve the cumulative efficient of reflection energy collecting plate to obtain larger reflective surface area, but so make the processing of reflecting surface increase difficulty, simultaneously because in a single day the just necessary integral replacing of local damage appears in reflecting surface, and the reflection energy collecting plate so that the damage probability of reflection energy collecting plate reflecting surface is very large, thereby has increased use cost because its work characteristics must be exposed outdoor.
Summary of the invention
For the existing the problems referred to above of existing reflection energy collecting plate, the invention provides a kind of reflection energy collecting plate that needn't after the reflecting surface local damage, carry out integral replacing.
The technological means that technical solution problem of the present invention adopts is:
A kind of reflection energy collecting plate, comprise body and reflecting layer with radian, described reflecting layer is overlying on described body surface and cooperates the radian of described body that the light of the described body of irradiation is concentrated and reflexes in described the external presumptive area, wherein, described reflecting layer mainly is put together by the identical reflecting material of multi-disc material.
Above-mentioned reflection energy collecting plate, wherein, described body mainly contains the identical hard material of multi-disc material and is put together.
Above-mentioned reflection energy collecting plate, wherein, the pieces of reflective material number that amalgamation forms described reflecting layer equals or forms more than amalgamation the sheet number of the hard material of described body.
Above-mentioned reflection energy collecting plate, wherein, the length that amalgamation forms the reflecting material in described reflecting layer equals the length of described body, and the width of described body is the integral multiple of described reflecting material width.
Above-mentioned reflection energy collecting plate, wherein, the length of described body is the integral multiple of the length of the amalgamation reflecting material that forms described reflecting layer, the width of described body is the integral multiple of described reflecting material width.
Above-mentioned reflection energy collecting plate, wherein, described body is made by honeycomb boards.
The invention has the beneficial effects as follows:
Body and reflecting layer are amalgamation and form, and only need change a slice of wherein damaging during local damage and needn't all change.
Description of drawings
Fig. 1 is that a kind of energy collecting plate that reflects of the present invention adopts the amalgamation of strip reflecting material to form the structural representation in reflecting layer;
Fig. 2 is that a kind of energy collecting plate that reflects of the present invention adopts block reflecting material amalgamation to form the structural representation in reflecting layer.
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments, but not as limiting to the invention.
As shown in Figure 1, the present invention is a kind of to be reflected energy collecting plate and comprises body 1 and reflecting layer 2 with radian, reflecting layer 2 is overlying on body 1 surface and cooperates the radian of body 1 that the light of irradiation body 1 is concentrated in the presumptive area that reflexes to outside the body 1, wherein, reflecting layer 2 mainly is put together by the identical reflecting material 21 of multi-disc material, amalgamation forms the measure-alike of dimensions behind the reflecting layer 2 and body 1, and the consistent flatness of maintenance and body 1.The reflecting material 21 that amalgamation forms reflecting layer 2 can be film class material or with the sheet material of reflectance coating.Form the reflecting material 21 that reflecting layer 2 makes reflecting layer 2 only need change failure area when the local damage by 21 amalgamations of multi-disc reflecting material and get final product, will be all with the defective of changing thereby overcome the local damage of existing reflection energy collecting plate reflecting surface.
On the technique scheme basis, body 1 can be put together by the identical hard material 11 of multi-disc material, because the size of reflection energy collecting plate has increasing trend, whole processing is comparatively difficult with the body 1 of radian, and transportation and installation are also very inconvenient, formed processing, transportation and the installation difficulty that can greatly reduce body 1 by 11 amalgamations of multi-disc hard material, in case and body 1 local damage also can adopt the method for replacing failure area hard material 11 to safeguard, reduced use cost.
Further, wherein the amalgamation sheet number that forms the reflecting material 21 in reflecting layer 2 can equal or form more than amalgamation the sheet number of the hard material 1 of body 1.The sheet number that forms the reflecting material 21 in reflecting layer 2 such as amalgamation forms body 1 than amalgamation the sheet number of hard material 1 is few, then the area of every reflecting material 21 coverings is larger, so that reflecting layer 2 may be only because must change large-area reflecting material 21 during a less local damage, use cost is increased.
Further, as shown in Figure 1, the length of the reflecting material 21 in amalgamation formation reflecting layer 2 can equal the length of body 1, and the width of body 1 can be the integral multiple of reflecting material 2 width.Be that reflecting material 21 is strip tiling amalgamation and forms reflecting layer 2, only need change one of failure area or several reflecting materials 21 during 2 local damage of reflecting layer and get final product.
The length that also can make body 1 is the integral multiple of the length of the amalgamation reflecting material 21 that forms reflecting layer 2, the width of body 1 is the form of the integral multiple of reflecting material 21 width, as shown in Figure 2, be that reflecting material is that block tiling amalgamation forms reflecting layer 2, only need change one of failure area or several reflecting materials 21 during reflecting layer 2 local damage gets final product, like this so that the gross area of the reflecting material 21 that need change during local damage can be less, and then so that replacement cost reduce.
Further body 1 can be formed after abnormal shape processing by honeycomb boards, makes body 1 by honeycomb boards and makes the larger strength-weight ratio of body 1 acquisition, and mean forced, compression resistance are strong, and shock resistance is good and not yielding.
The above is only for preferred embodiment of the present invention, is not so limits claim of the present invention, so the equivalent structure that all utilizations specification of the present invention and diagramatic content have been done changes, all is included in protection scope of the present invention.
