Abstract

The invention discloses a photovoltaic module with efficient heat dissipation. The photovoltaic module with efficient heat dissipation comprises solar high-transmittance coated glass, an EVA packaging layer and a photovoltaic backplane from bottom to top in sequence. Crystalline silicon is arranged on the EVA packaging layer. An aluminum alloy frame is arranged on the periphery of a laminate composed of the solar high-transmittance coated glass, the EVA packaging layer and the photovoltaic backplane. The laminate is connected with a junction box. According to the photovoltaic module with efficient heat dissipation, due to the fact that the front panel coated glass of the photovoltaic module stops infrared light, the heating function of the infrared light on a cell piece is eliminated; a heat dissipation groove structure is arranged on the outer surface of a glass sheet, and therefore heat dissipation of the light incidence surface of the photovoltaic module is enhanced. In addition, a 1mm heat dissipation groove is formed in the air side of the backplane, a heat dissipation groove is further formed in the outer surface of the aluminum alloy frame, and the junction box is a heat-dissipation junction box. Therefore, the heat dissipation efficiency of the module is greatly improved, the temperature of the module is lowered, the power of the module is increased, and the service life of the module is greatly prolonged.

Description

Heat radiation high-efficiency photovoltaic assembly
Technical field
The present invention relates to a kind of photovoltaic module, belong to the photovoltaic technology field.
Background technology
Photovoltaic module is the core parts of photovoltaic generation application.The front glass sheet of the photovoltaic module of suitability for industrialized production does not have the reflects infrared light good characteristic both at home and abroad at present, can cause like this temperature of component internal to raise, thereby cause the power output of assembly and useful life to descend, and backboard AIR side face does not have radiator structure, thereby can't effectively the dissipation of heat of assembly be gone out, cause the temperature of assembly effectively not reduce, thereby affect the heat dispersion of assembly, and then affect the power output of photovoltaic module.Simultaneously, use conventional plastic junction box, easily cause the terminal box internal temperature higher, damage the useful life of inner member, and then affect the useful life of assembly.And the surfacing of conventional aluminum alloy frame, the heat distributed in the unit interval is limited.
Summary of the invention
The object of the present invention is to provide a kind of material appropriate, rational in infrastructure, the photovoltaic module of energy efficiently radiates heat, the working temperature of reduction assembly cell piece, improve the power output of assembly and the heat radiation high-efficiency photovoltaic assembly in useful life.
Technical solution of the present invention is:
A kind of heat radiation high-efficiency photovoltaic assembly, comprise solar energy high coated glass, EVA encapsulated layer, photovoltaic back thoroughly from bottom to up successively, in the EVA encapsulated layer, is provided with crystalline silicon; The lamination periphery of above-mentioned each layer of composition is equipped with aluminum alloy frame, after framing up, refills terminal box.
High coated glass thoroughly is high transmission rate and surface with radiator structure and infrared light is had to the coated glass of cut-off.
Air one side of backboard has the radiating groove that spacing is 1mm.
The outer surface of aluminium alloy is with radiating groove.
Described EVA encapsulated layer is to have the EVA encapsulating material that ends infrared light but UV is absorbed or sees through function.
Terminal box is heat dissipation type high aluminum terminal box.
The present invention utilizes photovoltaic module header board coated glass to eliminate the pyrogenic action of infrared light to cell piece to the cut-off of infrared light, and the outer surface at original sheet glass has the radiating groove structure simultaneously, strengthens the heat radiation of photovoltaic module light entrance face.The radiating groove of 1mm is also arranged in the air surface of backboard in addition, and the aluminium alloy outer surface also has radiating groove, and terminal box is the cooling aluminum terminal box.The large like this heat dissipation of strengthening assembly, reduced assembly temperature increase the power of assembly, greatly promoted useful life of assembly simultaneously.And have the coated glass light transmittance of radiating groove greatly to promote, and use UV to see through the EVA encapsulating material of IR-cut, thus promote the power output of photovoltaic module, improve the accumulated generation amount of assembly.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the generalized section of one embodiment of the present of invention.
Fig. 2 is the front view of the embodiment of the present invention.
Fig. 3 is the rearview of the embodiment of the present invention.
Embodiment
A kind of heat radiation high-efficiency photovoltaic assembly, comprise solar energy high coated glass 1, EVA encapsulated layer 2, photovoltaic back 3 thoroughly from bottom to up successively, is provided with crystalline silicon 4 in the EVA encapsulated layer; The lamination periphery of above-mentioned each layer of composition is equipped with aluminum alloy frame 5, and lamination is connected to terminal box 6.
High coated glass thoroughly is high transmission rate and surface with radiator structure and infrared light is had to the coated glass of cut-off.
Air one side of backboard has the radiating groove that spacing is 1mm.Backboard is high reflective back plane.
The outer surface of aluminium alloy is with radiating groove.
Described EVA encapsulated layer is to have the EVA encapsulating material that ends infrared light but UV is absorbed or sees through function.
Terminal box is heat dissipation type high aluminum terminal box.
Make heat radiation high-efficiency photovoltaic assembly after the operations such as solar photovoltaic assembly adopts conventional single weldering, series welding, stacked, lamination, frame up.
Innovative point of the present invention is a plurality of critical materials of photovoltaic module and structure are related to the increase cooling mechanism, and eliminate the input of infrared light at this bi-material of glass and EVA, thereby increased the cooling ability of assembly, promote the power of assembly, guaranteed useful life and the accumulated generation amount of solar photovoltaic assembly.The present invention compares with traditional solar photovoltaic assembly, and the aspects such as heat radiation and raising component power have significant progress.
All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of requirement of the present invention.
