Description
Technical field
The utility model relates to a kind of solar components, particularly relates to a kind of two glass solar components.
Background technology
Two glass solar components increases gradually in the share in market, two glass solar components, front and back all uses glass as cover plate, and glass ageing-resistant performance is excellent, and sealing is splendid, but the EVA of two sheet glass surroundings is directly exposed in air, directly contact with the steam of open air, EVA dissolving is hydrolyzed aging, and the bonding force of EVA and glass also easily lost efficacy, cause the significant deficiency such as the failure of insulation of solar components, therefore the surrounding of two glass assembly becomes the weak spot of product quality; In disclosed patent CN103383973, describe a kind of two glass solar components novel encapsulated mechanism, the shape that its structure levels glass plate all needs special one-tenth special, virtually add production cost, a kind of solar components is described in the patent CN203644801U announced, its internal structure merely illustrates the sandwich construction of two glass solar components, do not pay attention to the EVA problem of aging in actual production process, therefore, there is this defect in prior art, is badly in need of a kind of technical scheme and solves.
Summary of the invention
The purpose of this utility model is to provide one that EVA can be prevented aging, increases two glass solar components in life-span.
In order to achieve the above object, the utility model comprises upper and lower glass cover-plate and cell piece, also comprise EVA encapsulated layer, bead layer, the both sides up and down of cell piece are equipped with EVA encapsulated layer respectively, in the outside of EVA encapsulated layer, correspondence is provided with upper and lower glass cover-plate respectively, be provided with bead layer in the surrounding of cell piece and EVA encapsulated layer, the side seal of described bead layer connects EVA encapsulated layer, and its upper and lower two ends are tightly connected upper and lower glass cover-plate respectively.
The utility model adopts independent sealant in the surrounding of solar components, instead of the structure in the past adopting EVA encapsulated layer overall package, solves EVA aging, the problem that cell panel is etched, improve the useful life of solar components.
Described EVA encapsulated layer thickness is 0.3mm-0.8mm.The utility model EVA encapsulated layer thickness can not be blocked up in order to avoid stop the transmission of solar energy.
Described bead layer is POE bead layer, and its shape is strip, and its cross-sectional height is more than or equal to the thickness of double-deck EVA encapsulated layer and cell piece, and its cross-sectional width is 3mm-20mm.Bead layer of the present utility model preferably adopts POE material, and this material permeability rate is low and glass bonding force is good, for the integral sealing encapsulation of solar components provides strong support.The utility model preferably POE bead layer equals the thickness of double-deck EVA encapsulated layer and cell piece.
Described EVA encapsulated layer four edge lengths is less than upper and lower glass cover-plate 3mm-20mm.EVA encapsulated layer and bead layer are connected, and leave remaining limit, for the filling of bead layer provides space.
The part bead layer that described EVA encapsulated layer four limit is less than upper and lower glass cover-plate is filled.
The layer that EVA encapsulated layer is corresponding with upper glass cover-plate is hyaline layer, and the layer that EVA encapsulated layer is corresponding with lower-glass cover plate is hyaline layer or white layer.
Described bead layer and upper and lower glass cover-plate junction are smooth surface or matsurface or streak face.
POE bead layer can be sealed to the surrounding of solar components by smooth surface of the present utility model well, there is good sealing function, matsurface can increase pastes later frictional force, it is multi-layer sealed that streak face can ensure that bead layer is formed, and concavo-convex sealing POE material can ensure sealing effectiveness.
The utility model adopts technique scheme, good sealing effectiveness can be reached, two glass solar components is carried out structural improvement, and then reach the effect greatly improving the life-span, avoid impurity in steam and air and, to the corrosion of EVA material, while ensure that cell panel safety, ensure that the penetrating degree of EVA material, to the collection of solar energy advantageously, there is good market using value and prospect.
