A kind of backboard radiator structure of solar panel
Technical field
The utility model relates to a kind of solar power generation assembly, and particularly a kind of backboard radiator structure of solar panel belongs to the solar panel technology field.
Background technology
The energy and environmental problem are the focus of world attention in recent ten years, and in order to realize the sustainable development of the energy and environment, countries in the world are all with the emphasis of photovoltaic generation as development.Some large public buildings, roof have big, the surperficial clean and tidy characteristics of area, are the optimum carriers as the city solar cell, especially are suitable for installing additional the solar power generation assembly.Solar panel is after being subjected to illumination, luminous energy changes into the electric energy except that part, and most of meeting produces heat energy, and the solar panel temperature influence is very responsive, the temperature rising can make its generating conversion efficiency obviously descend, and causes the whole energy output of solar cell to reduce.
How the tactic pattern of existing solar power generation assembly is with glass and TPT(polyvinyl fluoride) or other macromolecular materials as the back veneer material of solar panel, but these materials are unfavorable for the heat radiation of solar panel because heat conductivity is poor.
Summary of the invention
The purpose of this utility model is: a kind of backboard radiator structure of solar panel is provided, solves because temperature raises, and the problem that the solar panel conversion efficiency is reduced.
For achieving the above object, the technical scheme that adopts is: a kind of backboard radiator structure of solar panel, comprise the toughened glass panel, upper strata EVA film, solar panel, the EVA of lower floor film and the backing material that are fixedly connected sequentially from top to bottom, it is characterized in that: described backing material below is adhesively fixed with honeycomb aluminium core and is connected.
Described honeycomb aluminium core below is equipped with aluminum alloy bottom plate, and the connection that is adhesively fixed mutually.
Described aluminum alloy bottom plate is equipped with the heat radiation through hole.
Good effect of the present utility model is: a kind of backboard radiator structure of solar panel, owing to adopt honeycomb, increased the area of dissipation of solar photovoltaic assembly greatly, the efficient heat conductivity of aluminium alloy also can make the heat of solar panel scatter and disappear fast simultaneously, thereby avoided because temperature raises, made the problem of the photoelectric conversion rate decline of solar cell.Simultaneously, because the backing material below is adhesively fixed with honeycomb aluminium core and aluminum alloy bottom plate, improved the stress performance of solar components greatly.
Description of drawings
Illustrate with reference to the accompanying drawings below and embodiment that the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
Among the figure, the 1--toughened glass panel; 2,2 '--the EVA film; The 3--solar panel; The 4--backing material; 5--honeycomb aluminium core; The 6--aluminum alloy bottom plate; The 7--through hole that dispels the heat.
Embodiment
Fig. 1 is a structural representation of the present utility model, as seen from the figure, a kind of backboard radiator structure of solar panel, comprise the toughened glass panel 1, upper strata EVA film 2, solar panel 3, the EVA of lower floor film 2 ' and the backing material 4 that are fixedly connected sequentially from top to bottom, it is characterized in that: described backing material 4 belows are adhesively fixed with honeycomb aluminium core 5 and are connected.
Described honeycomb aluminium core 5 belows are equipped with aluminum alloy bottom plate 6, and the connection that is adhesively fixed mutually.
Described aluminum alloy bottom plate 6 is equipped with heat radiation through hole 7.
During assembling, make earlier solar photovoltaic assembly, described solar panel 3 is connected according to some, make solar panel 3 simultaneously by upper strata EVA film 2 and the EVA of lower floor film 2 '
' Protection, fixing with toughened glass panel 1 and backing material 4 bondings.The solar photovoltaic assembly that above step is made is laid honeycomb aluminium core 5 in lower surface one side of backing material 4, the honeycomb aluminium core 5 and backing material 4 bondings of solar photovoltaic assembly are fused by polyurethane adhesive.
Honeycomb aluminium core 5 can be used band heat radiation through hole 7, or not with aluminum alloy bottom plate 6 back covers of heat radiation through hole 7, the polyurethane adhesive bonding is fixed.
