Description
Technical field
The present invention relates to a kind of welder used for solar batteries, relate to or rather the invention of the wrapped type solar cell photovoltaic welding of a kind of Copper Foil spiral aspect.
Background technology
Photovoltaic welding belt is the welder being used on photovoltaic module, mainly plays the effect that connects conduction. The critical technical parameter of welding device comprises solderability, tensile strength, percentage elongation, resistivity. Conventional welding device is that the method that is coated with tin by heat is prepared from the copper strip surface of a kind of high-elongation, high tensile, high conduction at present. Along with the raising of solar panel transformation efficiency, electric current by welding inside is increasing, therefore just require the conductive area of welding constantly to increase, but along with the increase of welding thickness, the flexibility of welding is also reducing, and the welding after simultaneously thickening can bring larger thermal stress to cell piece, causes the probability of cell piece breakage to increase, therefore need to propose the welding of a kind of high flexibility, high conductive area, to solve the problem in current solar-photovoltaic technology field.
As can be seen here, above-mentioned existing welding device still has many defects, need to be improved.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcomes the defect that existing welding device exists, and the wrapped type solar cell photovoltaic of a kind of Copper Foil spiral welding is provided.
The present invention solves its technical problem underlying and realizes by the following technical solutions. the wrapped type solar cell photovoltaic of the Copper Foil spiral welding proposing according to the present invention, comprise the belt body of flat extending longitudinally, belt body comprises conductor wire and Copper Foil band, the wrapped conductor wire of Copper Foil band spiral, the surface of Copper Foil band applies tin layer, above-mentioned Copper Foil band separates in the major axis bearing of trend space of belt body, the spacing of adjacent Copper Foil band is 1/5th to 1/2nd of Copper Foil band cross-sectional width, above-mentioned conductor wire is arranged in parallel by conductive filament or the system of twisting forms, the thickness of above-mentioned Copper Foil band is 20 microns to 350 microns, the thickness of above-mentioned painting tin layer is 10 microns to 50 microns.
The present invention compared with prior art has obvious advantage and beneficial effect. From above technical scheme, the present invention is owing to adopting technique scheme to bring multiple advantage, and the wrapped conductor wire of Copper Foil band, can increase the flexibility of belt body, reduces the thermal stress of welding position.
Above-mentioned explanation is only the general introduction of technical solution of the present invention feature part, for making professional and technical personnel can better understand technological means of the present invention, and can be implemented according to the content of description, below with preferred embodiment of the present invention and coordinate accompanying drawing to be described in detail as follows.
