Abstract
The utility model discloses a solar cell module with a supporting structure. The solar cell module comprises a laminated piece in an aluminum frame (5). The laminated piece is composed of a piece of toughened glass (1), a first EVA layer (21), a solar cell piece (3), a second EVA layer (22) and a backboard (4), which are stacked and arranged from top to down. The supporting structure (6) is fixedly arranged between the lower surface of the backboard (4) and the aluminum frame (5). The supporting structure is combined with the aluminum frame and the backboard via heat-conduction silica gels (7). The supporting structure is made of metal materials. The part of the supporting structure combined with the backboard has a thickness of 2-6mm. The supporting structure of the module enhances the mechanical strength of the module, improves the bending phenomenon of the module, increase the heat-radiating ability of the module, reduces the working temperature of the cell piece, and indirectly enhances the output power of the module as well.
Description
Technical field
The utility model relates to technical field of solar, particularly a kind of solar module that has supporting construction.
Background technology
Along with traditional fuel energy reduces day by day, the harm that environment is caused constantly aggravates, and countries in the world have all been invested regenerative resource to sight, hopes that regenerative resource can change human energy resource structure, keeps long-range sustainable development.Wherein solar energy forms the focus of paying attention to into people with its exclusive advantage.Abundant solar radiant energy is an important energy, is inexhaustible, nexhaustible, pollution-free, cheap regenerative resource.
Application the most widely is a photovoltaic generation in the numerous application of solar energy; The elementary cell of solar energy power generating is a solar cell; In concrete application; Normally a plurality of solar battery sheets are constituted solar modules, and then each solar module is coupled together integrant electric current output.Present widely used solar module is mainly conventional monocrystalline silicon, polysilicon and amorphous silicon membrane assembly.
Solar module mainly is an integral body that solar cell package is become with toughened glass, EVA (ethylene-vinyl acetate), backboard and frame; In traditional component process, the protection of assembly and support mainly depend on toughened glass and aluminum alloy frame.Because the area of assembly is bigger, the weight of himself is also very big, and the contact-making surface of aluminium frame and assembly is less; The span of assembly is bigger; Can make the assembly that is packaged in the aluminium frame produce certain bending like this, bear the pressure of 5400Pa, if assembly keeps crooked state for a long time although the mechanical strength of aluminium frame can guarantee assembly; Will certainly add the macrocell sheet the latent probability that splits takes place, cause the decay and the inefficacy of assembly power output at last.In addition; The backboard of existing assembly generally is a polyester material; Its thermal conductivity is very little, owing to backboard is the important channel of interior battery sheet of assembly and external environment condition generation heat exchange, therefore uses the backboard thermal diffusivity of polyester material all relatively poor; Cause the working temperature of battery sheet too high, reduced the real output of assembly.
The utility model content
The utility model technical problem to be solved is to provide a kind of solar module that has supporting construction, and this supporting construction guarantees that assembly has enough mechanical strengths, has reduced the buckling phenomenon of assembly simultaneously, has strengthened the heat dispersion of assembly.
The technical scheme that the utility model addresses the above problem is following:
A kind of solar module that has supporting construction comprises the laminate that is installed in the aluminium frame, and said laminate is made up of range upon range of toughened glass of arranging, an EVA layer, solar battery sheet, the 2nd EVA layer and backboard from top to bottom, it is characterized in that:
Be installed with supporting construction between the lower surface of said backboard and the aluminium frame.
As optimal way, combine through heat conductive silica gel between said supporting construction and aluminium frame and the backboard.
Said supporting construction is a metal material, and said metal material is aluminum alloy materials, steel or copper.
Described supporting construction and backboard bound fraction thickness are 2～6mm.
Compare with the assembly of routine, the beneficial effect of the utility model is:
This solar module that has supporting construction reduces or has eliminated the buckling phenomenon of assembly owing to having increased support component at aluminium frame and backboard place, has protected the solar battery sheet in the assembly, has increased the mechanical strength of assembly simultaneously; On the other hand, supporting construction and backboard have bigger contact area, make the interior heat that produces of assembly to scatter and disappear very soon in environment, reduce the working temperature of battery sheet, have improved the power output of assembly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
Fig. 1 is a kind of part sectioned view that has the solar module of supporting construction of the utility model.
Wherein, 1 is toughened glass, and 21 is an EVA layer, and 22 is the 2nd EVA layer, and 3 is solar battery sheet, and 4 is backboard, and 5 is the aluminium frame, and 6 is supporting construction, and 7 is heat conductive silica gel.
Embodiment:
As shown in Figure 1; A kind of solar module that has supporting construction; Comprise the laminate that is installed in the aluminium frame (5); Said laminate is made up of range upon range of toughened glass of arranging (1), an EVA layer (21), solar battery sheet (3), the 2nd EVA layer (22) and backboard (4) from top to bottom, is installed with supporting construction (6) between the lower surface of said backboard (4) and the aluminium frame (5).
As preferably, combine through heat conductive silica gel (7) between said supporting construction (6) and aluminium frame and the backboard.
Said supporting construction (6) is a metal material, and said metal material is preferably aluminum alloy materials, steel or copper.
Said supporting construction (6) is 2～6mm with backboard bound fraction thickness.As preferably, its thickness is 5mm.
Compared with prior art; Because the assembly of the utility model has been set up supporting construction; This structure has increased the supported area of assembly, has increased the mechanical strength of assembly on the one hand, has greatly reduced the buckling phenomenon of assembly; Reduce the battery sheet the latent probability that splits has taken place, made assembly can bear bigger blast and crushing by snow; On the other hand, supporting construction has good heat sinking function, and itself and the bigger contact area of backboard make the heat in the assembly to conduct through this structure fast, have reduced the working temperature of battery sheet, have improved the power output of assembly.
