Description

Technical Field

[0001] The present disclosure relates to the field of photovoltaic technology, and in particular to a frame and a photovoltaic module. Background Art

[0002] Photovoltaic modules are the most important part of a solar power generation system. They include a photovoltaic laminate and a frame surrounding the photovoltaic laminate. The frame is used to seal and fix the circumferential edge of the photovoltaic laminate where solar cells are installed.

[0003] Traditional frames are usually higher than photovoltaic laminates, which can easily cause dust accumulation on the surface of the photovoltaic laminates, affect the power generation of the solar panels, and even cause local hot spots, resulting in damage or scrapping of the solar panels. Therefore, in the existing technology, in order to prevent dust accumulation, the A surface of the frame used to clamp the photovoltaic laminates is removed, and the frame is designed as a frame structure without an A surface to eliminate the height difference between the A panel and the photovoltaic laminates, so that dust or accumulated water can flow out of the photovoltaic modules.

[0004] However, since the existing frame structure and the photovoltaic laminate are usually fixed by silicone bonding, the installation groove lacks A-side protection, which causes the glue in the installation groove to easily overflow and pollute the production line. Moreover, since there is less glue on the side walls and bottom walls of the installation groove on the frame structure, the bonding and fixing effect of the photovoltaic laminate is poor, affecting the load of the frame.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. Throughout the present disclosure, "plurality" means two or more, unless otherwise specifically defined.

[0035] The following describes the embodiments of the present invention in conjunction with the accompanying drawings.

[0036] Please also refer to Figure 1 、 Figure 2 and Figure 3The embodiment of the present disclosure provides a frame 10, which includes a frame body 11 and a fixing plate 12. The frame body 11 is used to support an external photovoltaic laminate 20. The fixing plate 12 is connected to the top plate 111 of the frame body 11, and the fixing plate 12 and the top plate 111 of the frame body 11 are surrounded by a mounting groove 13 for mounting the photovoltaic laminate 20. The top plate 111 of the frame body 11 is provided with a first tooth portion 14 formed by a plurality of first protrusions. The first tooth portion 14 is used to support the photovoltaic laminate 20. The fixing plate 12 is provided with a second tooth portion 15 formed by a plurality of second protrusions. An anti-overflow glue groove 16 is formed on the mounting groove 13. The anti-overflow glue groove 16 is provided at the connection between the fixing plate 12 and the top plate 111 of the frame body 11. The anti-overflow glue groove 16 is used to store glue and prevent glue from overflowing. Specifically, the glue stored in the anti-overflow glue groove 16 is the same as the glue in the tooth groove formed by the first tooth portion 14, and both are silicone.

[0037] In the above-mentioned frame 10, first, glue is applied in the tooth groove formed by the first tooth portion 14 on the top plate 111 of the frame body 11 (i.e., the bottom wall of the mounting groove 13), and glue is applied in the tooth groove formed by the second tooth portion 15 on the fixing plate 12 (i.e., the side wall of the mounting groove 13). Then, the photovoltaic laminate 20 is bonded and fixed to the mounting groove 13 through the glue in the tooth groove formed by the first tooth portion 14 and the glue in the tooth groove formed by the second tooth portion 15, thereby realizing the bonding and fixation of the frame 10 and the photovoltaic laminate 20. Therefore, more glue can be stored in the tooth groove formed by the first tooth portion 14 and the second tooth portion 15, and the photovoltaic laminate 20 is supported by the first tooth portion 14, and the bonding area between the solid glue and the fixing plate 12 is increased by the second tooth portion 15, thereby improving the firmness of the photovoltaic laminate 20 bonded and fixed to the mounting groove 13. At the same time, by preventing overflow The glue groove 16 is arranged at the connection between the fixed plate 12 and the top plate 111 of the frame body 11, so that a part of the anti-overflow glue groove 16 is opened on the top plate 111 of the frame body 11, and the other part of the anti-overflow glue groove 16 is opened on the fixed plate 12, so that when the photovoltaic laminate 20 is installed from the outside to the inside, the excess silicone in the tooth groove formed by the first tooth portion 14 can be squeezed into the space where the anti-overflow glue groove 16 is located on the fixed plate 12, so as to prevent the silicone from overflowing and polluting the production line; in this way, the glue application amount is increased through the first tooth portion 14 structure and the second tooth portion 15 structure, and the bonding area of ​​the cured glue with the first tooth portion 14 and the second tooth portion 15 is increased, thereby greatly improving the bonding and fixing effect of the photovoltaic laminate 20 in the installation groove 13, ensuring the load stability of the frame 10, and also preventing the glue from overflowing and polluting the production line through the anti-overflow glue groove 16.

[0038] See also Figure 3In some embodiments, the tooth groove formed by the first tooth portion 14 includes a groove body 141 and a groove body 142. The groove body 141 and the groove body 142 are arranged in sequence along the top plate 111 of the frame body 11 from one end of the fixed plate 12 toward a direction away from the fixed plate 12. The groove body 141 and the groove body 142 are both inclined, and the inclination directions of the groove body 141 and the groove body 2 142 are opposite.

[0039] In this way, by setting the groove body 141 and the groove body 2 142 in opposite directions, the silicone stored in the groove body 141 and the groove body 2 142 is solidified to form a clamping structure with the groove body 141 and the groove body 2 142, so that the fixing effect between the solidified silicone and the inclined first tooth portion 14 is better, thereby further increasing the load of the frame 10.

[0040] See also Figure 3 In this embodiment, the cross-sectional area of ​​the first groove body 141 is larger than the cross-sectional area of ​​the second groove body 142, and the first groove body 141 is close to the anti-overflow glue groove 16, and the second groove body 142 is far away from the anti-overflow glue groove 16; specifically, the first groove body 141 has a wavy structure; in this way, more silica gel is stored in the first groove body 141 with a larger cross-sectional area to improve the bonding effect, and a larger support area for supporting the photovoltaic laminate 20 is formed by the second groove body 142 with a smaller cross-sectional area, so as to improve the supporting strength of the top plate 111 of the frame body 11.

[0041] See also Figure 3 In some embodiments, a support portion 19 is further provided on the top plate 111 of the frame body 11. The support portion 19 is provided on the side of the first tooth portion 14 away from the fixed plate 12, and the height of the support portion 19 is not lower than the height of the first tooth portion 14, that is, the height of the support portion 19 is higher than the height of the first tooth portion 14, or the height of the support portion 19 is the same as the height of the first tooth portion 14, so as to provide stable support for the photovoltaic laminate 20.

[0042] See also Figure 3 In some embodiments, the frame body 11 includes a top plate 111, a bottom plate 112 and two side plates 113. The top plate 111 is connected to the fixed plate 12, and the top plate 111 is provided with a first tooth portion 14 on the side facing the fixed plate 12. The bottom plate 112 and the top plate 111 are spaced apart, and the two side plates 113 are spaced apart, and one end of each side plate 113 is connected to the bottom plate 112, and the other end of each side plate 113 is connected to the top plate 111. The top plate 111, the bottom plate 112 and the two side plates 113 are surrounded to form a corner code cavity 114.

[0043] See also Figure 3 In some embodiments, the frame body 11 further includes reinforcing ribs connected to the side panels 113 to improve the supporting strength of the side panels 113 .

[0044] See also Figure 1 The embodiment of the present disclosure also provides a photovoltaic module, which includes a photovoltaic laminate 20 and the four aforementioned frames 10. The photovoltaic laminate 20 has two short sides 21 arranged opposite to each other and two long sides 22 arranged opposite to each other, wherein two frames 10 are respectively arranged around the two short sides 21 of the photovoltaic laminate 20, and the other two frames 10 are respectively arranged around the two long sides 22 of the photovoltaic laminate 20.

[0045] In this way, by setting an upper frame 10 on both short sides 21 of the photovoltaic laminate 20, so that a dust-proof structure can be adopted on both short sides 21 of the photovoltaic laminate 20, the light energy conversion efficiency and safety performance of the photovoltaic laminate 20 can be further improved. By setting a frame 10 on both long sides 22 of the photovoltaic laminate 20, so that the fixing effect of the photovoltaic laminate 20 can be improved on both long sides 22 of the photovoltaic laminate 20, the stability of the photovoltaic laminate 20 when being fixed can be improved.

[0046] Please also refer to Figure 4 and Figure 5 In some embodiments, each frame surrounding the long side 22 of the photovoltaic laminate 20 also includes an A panel 18, which is spaced apart from the top plate 111 of the frame body 11 and connected to the other end of the fixing plate 12 away from the top plate 111 of the frame body 11, and the A panel 18, the fixing plate 12 and the top plate 111 of the frame body 11 are surrounded by an installation groove 13 for installing the long side of the photovoltaic laminate 20.

[0047] In this way, the frame 10 surrounding the long side 22 of the photovoltaic laminate 20 is designed to have an A panel 18 structure, so as to improve the fixing effect between the frame 10 and the photovoltaic laminate 20, thereby increasing the load of the frame 10, and can effectively prevent glue overflow to avoid colloid contamination of the production line; at the same time, by organically combining the frame 10 with the frame 10 with the A surface, so as to ensure the load of the photovoltaic module, the photovoltaic laminate 20 is protected from dust and water accumulation.

[0048] In some embodiments, the top plate of the frame body 11 surrounding the short side 21 of the photovoltaic laminate 20 is fixed to the photovoltaic laminate 20 by liquid adhesive, and the fixing plate 12 is fixed to the photovoltaic laminate 20 by solid adhesive.

[0049] It can be understood that liquid glue is a colloid that is liquid before curing and solid after curing, and solid glue is a colloid that is solid before and after curing.

[0050] In this embodiment, the liquid glue is silicone and the solid glue is foam glue. The foam glue is solid before curing, and the bonding effect of the foam glue is close to that of silicone. Therefore, the foam glue is injected into the vertical fixed plate 12. The foam glue is solid glue and is not easy to flow, so that more foam glue can be stored on the fixed plate 12 to achieve better bonding effect. In addition, the solid glue has no squeezing and overflowing phenomenon, which can effectively prevent glue overflow.

[0051] Furthermore, the solid adhesive may also be a double-sided adhesive tape, and the double-sided adhesive tape has a strip structure.

[0052] In some embodiments, the frame body 11 surrounding the long side 22 of the photovoltaic laminate 20 is directly fixed to the photovoltaic laminate 20 by means of liquid adhesive.

[0053] The installation principle of the above-mentioned photovoltaic modules is roughly as follows:

[0054] First, silicone is injected into the tooth grooves formed by the first tooth portion 14 on the top plate 111 (i.e., the bottom wall of the mounting groove 13) of the frame body 11 for enclosing the short side 21 of the photovoltaic laminate 20, and into the anti-overflow glue groove 16. Foam glue is also injected into the tooth grooves of the second tooth portion 15 on the fixing plate 12 (i.e., the side wall of the mounting groove 13).

[0055] Then, the photovoltaic laminate 20 is bonded and fixed to the mounting groove 13 through the silicone in the groove formed by the first teeth 14 and the foam glue in the groove formed by the second teeth 15, thereby achieving bonding and fixing between the frame 10 and the short side 21 of the photovoltaic laminate 20;

[0056] Finally, silicone is injected into the tooth groove and anti-overflow glue groove 16 formed by the first tooth portion 14 on the frame body 11 for enclosing the long side 22 of the photovoltaic laminate 20, and foam glue or double-sided tape is injected into the fixing plate 12 to bond the photovoltaic laminate 20 to the installation groove 13 through silicone and foam glue, thereby achieving bonding and fixation between the frame 10 and the long side 22 of the photovoltaic laminate 20.

[0057] The above description is merely a specific embodiment of the present disclosure, but the scope of protection of the present disclosure is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this disclosure should be included in the scope of protection of the present disclosure. Therefore, the scope of protection of the present disclosure should be based on the scope of protection of the claims.
