Abstract
The utility model relates to a metal solar energy-collecting plate, which comprises a metal baseplate, a binding film, a reflecting film and a non-metal protecting film, wherein, the binding film is arranged on the light-receiving surface of the metal baseplate, the reflecting film is arranged on the surface of the binding film, and the non-metal protecting film is arranged on the surface of the reflecting film. The utility model sufficiently utilizes a metal substrate to replace a glass substrate and correspondingly arranges the binding film, the reflecting film and the non-metal protecting film on the light-receiving surface of the metal baseplate, and therefore the phenomenon that light must permeate the glass substrate for twice in order to be reflected in the prior art is avoided, thus effectively increasing light-collecting efficiency.
Description
Technical field
The utility model relates to a kind of solar energy condensation board, refers in particular to a kind of metal solar solar panel that promotes reflect focalization efficient.
Background technology
Solar energy thermal-power-generating, utilize catoptron with solar light focusing to the line style thermal-collecting tube, heating heat-carrying working medium, hot working fluid carries out heat interchange by heat interchanger and water and produces steam, pushing turbine drive generator for electricity generation.Efficient and durable reflecting plate is focus and a difficult point wherein; At present, existing reflecting plate is made of glass baseplate and the reflectance coating that is affixed on the glass substrate shady face usually, so utilize the way of internal reflection film to make light to see through glass baseplate twice, and glass baseplate has certain refraction and scattering to the light that sees through, the efficient of influence reflection; And glass baseplate transportation inconvenience, easy cracked breakage, volume are very big; Also there are some defectives in existing reflecting plate aspect making, for example glass baseplate must be through operations such as hot bending and tempering, if make the reflecting plate of slot type cambered surface, can only be to carry out plated film again after glass baseplate is configured as the arc parabola earlier, therefore, the reflecting plate that utilizes the glass baseplate plated film to make can be restricted because of factors such as optically focused, manufacturing, moulding, transportations, and total cost is higher, is unfavorable for market competition.
The utility model content
The utility model is at the existing disappearance of above-mentioned prior art, and fundamental purpose is to provide a kind of to be convenient to make, moulding, transportation and spotlight effect is good again metal solar solar panel.
For realizing above-mentioned purpose, the utility model is taked following technical scheme:
A kind of metal solar solar panel comprises:
One metal substrate;
One binding film, it is located on the side to light of metal substrate;
One reflectance coating, it is located on the binding film surface;
One nonmetal diaphragm, it is located on the reflectance coating surface.
Described metal substrate is slot type arcuation or plane.
Described reflectance coating is aluminium film or silverskin.
The utility model compared with prior art, its advantage is:
1, reflection efficiency is higher: utilize metal base instead of glass substrate; and be that corresponding binding film, reflectance coating, nonmetal diaphragm are set on the side to light of metal base; avoided to see through the phenomenon of glass baseplate reflection ray twice in the prior art, thereby promoted light gathering efficiency effectively.
2, transportation is more convenient: metal base can be done very thinly, and volume is little, can not damage.
3, make simpler: metal base can be earlier under flat state reshaping difformity behind the plated film, so the plated film mode is simpler.
4, easier moulding: metal base can save in the prior art glass baseplate through operations such as hot bending and tempering, and it only relies on the moulding of back up pad nature.
5, cost is lower: the metal base plated film is at aspects such as manufacturing, moulding, transportations, and total cost is lower than prior art glass baseplate plated film.
Description of drawings
Fig. 1 is that the utility model launches synoptic diagram;
Fig. 2 is the utility model schematic cross-section.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
See also Fig. 1, shown in Figure 2, a kind of metal solar solar panel comprises a metal substrate 1, is provided with binding film 2, reflectance coating 3 and nonmetal diaphragm 4 on the side to light 11 of this metal substrate 1 successively, wherein:
The utility model manufacture craft is as follows:
1, polishing on the side to light 11 of first metal substrate 1 makes it into smooth mirror surface, and cleans out;
2, plate one deck binding film again, guarantee that the adhesion of reflectance coating and base material is tight;
3, silver-plated then or aluminium mirror coating;
4, plate nonmetal diaphragm at last, with contacting of isolated reflectance coating and air.
Certainly, through the above-mentioned solar panel of finishing, also can be as required after having plated last nonmetal diaphragm bending forming slot type arc structure again, perhaps do not bend and be applicable to plane structure, this does not add and gives restriction again.
The utility model design focal point is to utilize metal base instead of glass substrate; and be that corresponding binding film, reflectance coating, nonmetal diaphragm are set on the side to light of metal base; avoided to see through the phenomenon of glass baseplate reflection ray twice in the prior art, thereby promoted light gathering efficiency effectively.Transport simultaneously more convenient, manufacturing is simpler, moulding is easier and cost is lower.
The above only is the preferred embodiment of a kind of metal solar solar panel of the utility model, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
