Abstract
The utility model relates to a kind of Copper Foil and indulges pouch-type solar cell photovoltaic welding, comprise the belt body of the flat of longitudinal extension, belt body comprises conductor wire and copper foil tape, described copper foil tape longitudinally doubling parcel conductor wire, the surface-coated tinning layer of described copper foil tape, the copper foil tape after doubling carries out heat fused welding at aperture position by tinning layer.The utility model provides technical scheme to bring multiple advantage; copper foil tape indulges bag conductor wire; the conduction flux of belt body can be increased and can flexibility be taken into account; heat fused welding is carried out by tinning layer in the position of vertical bagmouths open; play the effect of protection conductor; copper foil tape is because thickness is less, and the thermal stress applied to cell piece at the position with welding of battery film is little, avoids thermal stress to the destruction of cell piece.
Description
Technical field
The utility model relates to a kind of welder used for solar batteries, relates to the invention that pouch-type solar cell photovoltaic welding aspect indulged by a kind of Copper Foil or rather.
Background technology
Photovoltaic welding belt is the welder be used on photovoltaic module, mainly plays the effect connecting conduction.The critical technical parameter of welding device comprises solderability, tensile strength, elongation, resistivity.Welding device conventional is at present the copper strip surface at a kind of high-elongation, high tensile, high connductivity, and the method being coated with tin by heat is prepared from.Along with the raising of solar panel transformation efficiency, increasing by the electric current of welding inside, therefore just require that the conductive area of welding constantly increases, but along with the increase of welding thickness, the flexibility of welding is also in reduction, and the welding after simultaneously thickening can bring larger thermal stress to cell piece, causes the probability of cell piece breakage to increase, therefore the welding proposing a kind of high flexibility, high connductivity area is needed, to solve the problem in current solar-photovoltaic technology field.
As can be seen here, above-mentioned existing welding device still has many defects, needs to be improved.
Summary of the invention
Technical problem underlying to be solved in the utility model is, overcomes the defect that existing welding device exists, and provides a kind of Copper Foil to indulge pouch-type solar cell photovoltaic welding.
The utility model solves its technical problem underlying and realizes by the following technical solutions.Pouch-type solar cell photovoltaic welding is indulged according to the Copper Foil that the utility model proposes, comprise the belt body of the flat of longitudinal extension, belt body comprises conductor wire and copper foil tape, described copper foil tape longitudinally doubling parcel conductor wire, the surface-coated tinning layer of described copper foil tape, the copper foil tape after doubling carries out heat fused welding at aperture position by tinning layer.
Better, by conductive filament, arranged in parallel or strand system forms above-mentioned conductor wire.
Better, the thickness of above-mentioned copper foil tape is 20 microns to 350 microns.
Better, the thickness of above-mentioned tinning layer is 10 microns to 50 microns.
The utility model compared with prior art has obvious advantage and beneficial effect.From above technical scheme; the utility model is owing to adopting technique scheme; copper foil tape indulges bag conductor wire; the conduction flux of belt body can be increased and can flexibility be taken into account; carry out heat fused welding in the position of vertical bagmouths open by tinning layer, play the effect of protection conductor, copper foil tape is because thickness is less; the thermal stress applied to cell piece at the position with welding of battery film is little, avoids thermal stress to the destruction of cell piece.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model feature part, technological means of the present utility model is better understood for enabling professional and technical personnel, and can be implemented according to the content of specification, coordinate accompanying drawing to be described in detail as follows with preferred embodiment of the present utility model below.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.
