Description
Technical field
The present invention relates to be the Application of Solar Energy technology, the solar energy heating heat preservation component that particularly a kind of low-cost high-efficiency is energy-conservation.
Background technology
Two kinds of photo-thermal and photoelectricity are arranged in the Application of Solar Energy at present, in photo-thermal is used, generally adopt flat-plate solar heat collector; In photovoltaic applications, be generally used in PVT assembly (assembly of photovoltaic/thermal one).
Flat plate collector mainly contains following parts: glass, coating, absorber plate (being called for short the plate core), heat-insulation layer, backplate, frame.Glass sees through sunlight, and the distance between glass and the absorber plate is generally the air heat insulating layer about 3.2mm.Scribble coating on absorber plate, this coating both can make the heat absorption panel absorb more solar radiation, can reduce the heat loss through radiation loss of absorber plate to environment again.The absorber plate back is a heat-insulation layer, and heat-insulation layer mainly is to reduce heat collector to the heat radiation of environment all around, to improve the thermal efficiency of heat collector.Insulation material commonly used generally adopts: rock wool, mineral wool, polystyrene, polyurethane etc., general 3-5cm is thick for the bottom heat-insulation layer.Backplate generally adopts aluminium alloy, steel etc.Frame forms a whole and maintains certain rigidity and intensity and is convenient to install.The assembly of this structure is very thick, and is thick about 8～10cm greatly, and heaviness is not attractive in appearance; And in manufacturing process, expend a large amount of metals, insulation material and energy consumption (as welding).
In photovoltaic applications, a large amount of uses is crystal silicon solar energy battery at present, well-known, and the generating efficiency of crystal silicon cell can raise with temperature and descend, and concrete is: 1 ℃ of decrease in efficiency 3%～6% of the every rising of temperature.On based on traditional solar module structure, it is very high to add a surface smoothness, and cost is very low, and photo-thermal easy for installation partly is the photovoltaic/thermal system synthesis key in application that realizes solar power system.
Summary of the invention
The present invention is for addressing the above problem, a kind of heat-collecting heat-preserving of high-efficiency and energy-saving type solar energy cheaply parts are provided, can fully satisfy the application of plate solar collector and PVT assembly, aspect flat plate collector, the present invention is integrated in one the coating in the plate solar collector, plate core, heat-insulation layer, backplate function, both save material, simplified manufacture craft again, significantly reduced material and energy consumption in producing; Aspect the PVT assembly, a surface smoothness height, heat conduction is fast, cost is low, easy for installation photo-thermal parts are provided.
Technical scheme of the present invention is as follows:
A kind of high-efficiency and energy-saving type solar energy heat-collecting heat-preserving parts, it is characterized in that: comprise being used to accept solar radiation or other heat conducting collector metal exchange layer and being used to form the improved plastics structural shape that medium runner has reached insulation effect, collector metal exchange layer is tabular, evenly be provided with the surface plate of space on the improved plastics structural shape and to the medium chute of outer lug, fix by connector between the surface plate of collector metal exchange layer and improved plastics structural shape, junction between the surface plate of collector metal exchange layer and improved plastics structural shape is also by sealing adhesive linkage adhering and sealing, collector metal exchange layer and improved plastics structural shape by seal adhesive linkage bonding with become an integral body, the medium chute after connector is fastening, form a plurality of independently MEDIA FLOW passages between sealing adhesive linkage and the collector metal exchange layer.
Collector metal exchange layer is outer can also to be provided with coating for selective absorption, is used to absorb solar radiant energy.
Structure according to principle that absorbs sunshine and coating is different, coating for selective absorption can be divided into four classes:
(1) coated semiconductor
Coated semiconductor is to utilize in the electronic structure of semiconductor substance suitably energy gap Eg, absorbs the solar radiation photon of energy greater than Eg, enters conduction band thereby make the valence electron of material produce transition, and the photon of energy less than Eg seen through.So require the semiconductor substance energy gap to be preferably 0.62ev(1ev=1.602 * 10-19J), i.e. 9.939 * 10-20J.It absorbs visible light and does not absorb infrared ray, and Si, Ge are modal semi-conducting materials.The oxide of transition metal, sulfide all belong to compound semiconductor, as black chromium (Cr
xO
y), black nickel (NiS-ZnS), the black (Cu of cupric oxide
xO
y) and iron oxide (Fe
3O
4) etc.
(2) interference of light coating
Interference of light coating has been utilized the interference of light principle, deielectric-coating and absorbing composite membrane, metal substrate or bottom film by non-absorption are formed, and the refractive index and the thickness of the every tunic of strict control, make it produce destructive interference effect to the visible range, reduction is to the reflectivity of sunlight wavelength core, produce a broad absworption peak in the visible range, as Al
2O
3-Mox-Al
2O
3(AMA) trilamellar membrane, AlN-Al/Al eight tunics, OCLI multilayer film etc.
