Abstract
The utility model relates to a solar absorber plate with a starred surface. The surface of the absorber plate is composed of star-shaped quadrangles (1) and rhombic quadrangles (2), and the combination and connection structure of star-shaped quadrangles (1) is as follows: the tips (5) of each star-shaped quadrangle are connected with waist points (6) of the adjacent star-shaped quadrangles, and straight-edged rhombic triangles (4) are assembled in gaps (7) formed among all the connected star-shaped quadrangles. The utility model has the following notable advantages: the surface area is enlarged, so that the heat absorption capacity of the absorber plate can be increased per unit area; the area of the solar absorber plate is saved; the weight is reduced; the load is reduced; and the maintenance is convenient.
Description
Technical field:
The utility model belongs to the solar absorber plate technical field of structures.
Background technology:
Existing solar absorber plate, perhaps collection plate, what all adopt is surface plate.Under the increasing situation of present skyscraper, the absorber plate of solar water heater all is installed on the house roof, and a large amount of roof areas that account for are not only gained in weight, and increase the weight of the roof load, also to the waterproof of roof and heat insulation certain influence arranged; Solar absorber plate is roomy more, and front face area is just big more, is easy to generate damage and causes security incident; And the solar absorber plate at each family is set up separately, and all to the roof leak detection, building maintenance, absorber plate are repaired to change and brought bigger trouble.At present, the flat-faced tube solar absorber plate of use can only be adopted the heat of fixed amount in unit are.Equally, the collection plate collection effect of other solar power-generating facility remains the area of plane, and efficient is not high.
Summary of the invention:
The purpose of this utility model provides a kind of caloric receptivity that can increase for the above-mentioned defective that overcomes existing flat-faced tube solar absorber plate structure technology existence just in unit are, on less absorber plate, can adopt the solar absorber plate of bigger heat in other words, thereby save the solar absorber plate area, weight reduction, reduce load, the solar absorber plate of the surface band star spot of convenient for maintaining.
The purpose of this utility model is achieved by the following technical solution:
The utility model solar absorber plate surface is combined by star quadrangle and prismatic quadrangle; The star quadrangle is four identical symmetrical being formed by connecting of hypotenuse prismatic triangle; The prismatic quadrangle is two identical symmetrical being formed by connecting of straight flange prismatic triangle; The tetragonal combined connecting structure of star is: the tetragonal cusp of each star is connected with the tetragonal waist point of adjacent star; Formed space splicing straight flange prismatic triangle in all star quadrangles connect; The leg-of-mutton downward projection of the utility model hypotenuse prismatic oblique angle α is: 40 °～60 °; The utility model is formed the tetragonal hypotenuse prismatic of star triangle orthographic projection straight flange a and is 9～11:14～16 with adjacent side b length ratio; Optimum value is: 10:15; Straight flange prismatic triangle (4) the orthographic projection straight flange c that the utility model is formed prismatic quadrangle (2) is 8～10:12～14 with adjacent side d length ratio; Optimum value is: 9:13.
The beneficial effects of the utility model are, because the increase of surface area, the solar absorber plate of surface band star line shape can increase caloric receptivity in unit are, on less absorber plate, can adopt bigger heat in other words, thereby save the solar absorber plate area, weight reduction reduces load, convenient for maintaining.Choosing of the utility model optimum value, can be just right accept solar energy and not the exposure face ring and refraction is disturbed; The lower of band star line shape can ponding yet when raining simultaneously.The utility model not only is used for the heat accumulate plate of solar water heater, also can be used for the solar energy collecting plate that all solar energy utilize facility, comprises solar illumination apparatus such as street lamp, and the solar photoelectric display unit is as long-pending tabula rasa.Can both improve the solar energy acquisition efficient of unit are like this.The utility model can also be as the lampshade of illuminating lamp, and the star line shape on surface can be strengthened reflective, makes the illumination of light stronger.
Further set forth the utility model content below in conjunction with Figure of description and embodiment.
Description of drawings:
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cross-sectional schematic of Fig. 1;
Fig. 3 is the B-B cross-sectional schematic of Fig. 1.
The specific embodiment:
As Fig. 1, Fig. 2, Fig. 3, the utility model is combined the absorber plate surface by star quadrangle 1 and prismatic quadrangle 2; Star quadrangle 1 is four identical hypotenuse prismatic triangle 3 symmetrical being formed by connecting; Prismatic quadrangle 2 is two identical straight flange prismatic triangle 4 symmetrical being formed by connecting; The combined connecting structure of star quadrangle 1 is: the tetragonal cusp 5 of each star is connected with the tetragonal waist point 6 of adjacent star; Formed space 7 splicing straight flange prismatic triangles 4 in all star quadrangles connect; The downward projection oblique angle α of the utility model hypotenuse prismatic triangle 3 is: 40 °～60 °; The hypotenuse prismatic triangle 3 orthographic projection straight flange a that the utility model is formed star quadrangle 1 are 9～11:14～16 with adjacent side b length ratio; Optimum value is: 10:15; The straight flange prismatic triangle 4 orthographic projection straight flange c that the utility model is formed prismatic quadrangle 2 are 8～10:12～14 with adjacent side d length ratio; Optimum value is: 9:13.
The downward projection oblique angle α that embodiment one gets hypotenuse prismatic triangle 3 is: 45 °; The hypotenuse prismatic triangle 3 orthographic projection straight flange a that the utility model is formed star quadrangle 1 are 10mm, and b is 15mm, and the straight flange prismatic triangle 4 orthographic projection straight flange c that the utility model is formed prismatic quadrangle 2 are 9mm, and d is 13mm.Star quadrangle that this size relationship is formed respectively and prismatic quadrangle, its line prismatic shape and height energy the best reflect the result of use of thermal-arrest plate (light collecting plate).
The utility model adopts the thermal-arrest plate of band star spot to gather solar energy, under star spot rises and falls little situation, and the inevitable projected area of the developed area of star spot greater than it; Unit are can obtain the maximum hot side of adopting, thereby obtains the maximum heat of adopting.Especially when hypotenuse prismatic triangle 3 orthographic projection straight flange a were optimum value with straight flange prismatic triangle 4 orthographic projection straight flange c with adjacent side d length ratio with adjacent side b length ratio, the irradiation of the sun was not subjected to refractive effect, and the ridge height of rib is not enough to block sunlight.In other words, certain starlike wrinkle ridge height can be ignored fully.The downward projection oblique angle α one of hypotenuse prismatic triangle 3 determines that star quadrangle 1 shape has just determined that also the shape of prismatic quadrangle 2 has also been determined simultaneously.According to the tangent ratio of orthographic projection relation, just can obtain the size of star quadrangle 1 and prismatic quadrangle 2 respectively.Be used for making mould with this size, then when producing solar heat-collection plate by mold pressing, thermal-arrest plate surface is made the structure of being with star spot.If use, then adopt bottle blowing mould the vacuum tube surface can be made the structure of band star spot at solar energy vacuum tube.
