Description

Packaging device of photovoltaic module

Technical Field

The utility model relates to the technical field of photovoltaic module packaging, in particular to a packaging device of a photovoltaic module.

Background

At present, the packaging mode of the photovoltaic module is still the traditional plastic adhesive film aiming at 158.75/166/182/210 with different sizes, PERC/HJT/TOPCON with different technologies and the like, and the formula is adjusted only aiming at different battery pieces, and the change of the packaging process cannot be carried out. Therefore, the encapsulation of different components needs to pass through the laminating machine, and the energy consumption of one laminating machine is equivalent to burning 1.6 tons of standard coal, and the emission of 4.09 tons of carbon dioxide is increased. In conclusion, the photovoltaic module packaged by the plastic film wastes resources and causes environmental greenhouse problems, and the photovoltaic module may fail due to poor adhesion of the plastic film.

Fig. 1 is a schematic structural view of the present invention.

Detailed Description

The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the utility model but are not intended to limit the scope of the utility model.

As shown in fig. 1, the photovoltaic module packaging device provided by the utility model comprises a front glass 1, a back glass 2, a side glass 3 and a plurality of baffles 4, wherein the front glass 1 and the back glass 2 are connected through the side glass 3, the plurality of baffles 4 are uniformly installed and fixed on the front glass 1 at intervals, a gap formed by adjacent baffles 4 and a gap formed by the baffles and the side glass 3 are accommodating spaces for a battery string 6, the back glass 2 is provided with a plurality of holes for a bus bar to pass through, one end of the bus bar is connected with the battery string 6, and the other end of the bus bar is welded with a junction box 5.

Optionally, the front glass 1 and the back glass 2 are fixed by an aluminum frame after being connected by the side glass 3, so that the overall structure is relatively firm.

Optionally, the front glass 1 and the side glass 3 are of an integrated structure, so that the risk of leakage after the encapsulation liquid is injected is reduced.

Optionally, a gap between the junction box 5 and the back glass 2 is sealed by a sealant, so that leakage of a packaging liquid is avoided.

Optionally, the height of the side glass 3 is 1mm to ensure that the side glass is matched with the size of the battery string 6, so that the battery piece can be normally placed, and sufficient packaging liquid filling can also be ensured.

Taking a conventional photovoltaic module with 2094 × 1038 × 30 specification as an example, the front glass 1 and the back glass 2 are glass with a thickness of 2.0, and the baffle 4 is 0.5 × 2 × 1016 mm. When in use, the welded battery strings 6 are firstly placed in the space separated by the baffle 4, and the parallel short circuit between the battery strings 6 is prevented; then, the glass box body with the battery string 6 placed thereon is covered with back glass 2 for packaging, and the edge gap is sealed by sealing silica gel; and then, injecting a packaging liquid into the prepared glass box body, packaging the battery string 6 in the packaging liquid, preventing the battery piece 6 from being oxidized and losing efficacy, and preventing the battery piece 6 from colliding with the glass surface to generate fragments.

Wherein, the packaging liquid adopts transparent silica gel, and the components are as follows:

main material: vinyl polydimethylsiloxane;

vinyl-terminated silicone oil: vinyl content 0.28%;

catalyst: a platinum catalyst (platinum content 5000 ppm);

a crosslinking agent: a polymethylsiloxane;

an alkynyl cyclic alcohol;

hydrogen-containing silicone oil: the hydrogen content is 0.18 percent;

the content of each component can be set as required, and this example will not be described in detail.

All the optional technical schemes can be combined at will, and the structure after one-to-one combination is not explained in detail in the utility model.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, it should be noted that, for those skilled in the art, many modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
