Description

Technical Field

[0001] This application relates to the field of photovoltaic module technology, and in particular to a photovoltaic module frame and a photovoltaic module. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at semiconductor interfaces. When photovoltaic modules are placed outdoors for extended periods, dust, bird droppings, and other contaminants inevitably accumulate on their surfaces. This leads to a decrease in the light transmittance of the photovoltaic modules and, in severe cases, causes hot spot effects, affecting their lifespan. Current technologies utilize conventional A-side-less modules, short-side-wrapped modules, and short-side-perforated modules in conjunction with drainage and mud removal devices. These devices use the hydrophilic groups of polymer materials to disrupt the surface tension of the water-accumulating areas, thereby achieving the purpose of removing accumulated water and mud from the lower edge of the frame.

[0003] A frame without an A-side refers to a module frame where the side above the light-incident surface of the laminate is generally called the A-side. Without an A-side, this side is removed, meaning the module frame no longer contacts the light-incident surface of the laminate, forming a frame structure with an approximately L-shaped cross-section. However, conventional A-side-less modules, lacking a fixed side, have weakened mechanical load-bearing capacity and less effective securing to the laminate. They are also incompatible with existing gluing and framing equipment, frequently resulting in issues like glue overflow, insufficient glue, air bubbles, or frame detachment and reduced load-bearing capacity. The absence of an A-side in both long and short frame sections makes it easy for the laminate to detach from the back of the frame. Hollowed-out frame designs suffer from issues like insufficient glue, glue overflow, complex processing leading to increased costs and defect rates, and also suffer from reduced mechanical strength and increased susceptibility to deformation.

[0004] Therefore, it is necessary to design a photovoltaic module frame to solve the above problems. Utility Model Content

[0025] According to a first aspect of this utility model, a photovoltaic module frame is provided, such as... Figures 1 to 6 As shown, the photovoltaic module frame is used for mounting the laminate 3, which can be, for example, a glass interlayer as in the prior art. In this embodiment, it includes a first glass at the top and a second glass at the bottom, with a gap 301 formed between the first and second glass for accommodating a bonding adhesive (e.g., butyl hot melt sealant). The photovoltaic module frame includes a first abutting frame 1 and a second abutting frame 2.

[0026] In the following description, reference will be made to Figures 1 to 6 This section describes the detailed structure of the first abutting frame 1 and the second abutting frame 2 of the photovoltaic module frame.

[0027] like Figure 1 As shown, in this embodiment, the photovoltaic module frame includes a first abutting frame 1 and a second abutting frame 2 connected to each other. The first abutting frame 1 and the second abutting frame 2 can both be formed into an approximately elongated structure to fit the laminate 3, which is formed into a cuboid structure. The ends of the first abutting frame 1 and the ends of the second abutting frame 2 are connected to each other to form an approximately L-shaped frame, i.e., a "frame without an A-side".

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the first abutting frame 1 abuts against the first end face of the laminate 3, and the second abutting frame 2 abuts against the second end face of the laminate 3. The first end face of the laminate 3 can be perpendicular to the light incident surface, and the second end face of the laminate 3 can be away from the light incident surface. The first and second end faces of the laminate 3 can also be formed as another L-shaped structure to cooperate with the L-shaped frame. The laminate 3 is a photovoltaic product after thermal lamination, including a front panel, a battery chip, and a back panel stacked sequentially. Sealant is provided around the edges of the front panel and the back panel to form a sealed cavity between them for sealing and encapsulating the battery chip. The laminate 3 is a conventional product of the prior art and will not be described in detail here.

[0029] A snap-fit ​​receiving portion 101 is provided at the center of the first end face of the first abutting frame 1, which can snap-fit ​​the following snap-fit ​​adhesive strip 4. Adhesive-receiving cavities 106 are provided on both sides of the snap-fit ​​receiving portion 101 in the direction perpendicular to the light incident surface. The direction perpendicular to the light incident surface can be understood as... Figure 1 and Figure 2 The vertical direction is perpendicular to the light incident surface of the laminate 3. The adhesive cavity 106 can hold the cured adhesive to prevent it from delaminating. On the other hand, the sufficiently large adhesive cavity 106 can cooperate with the snap-fit ​​receiving part 101 to press against the first end face of the laminate 3, thereby reducing adhesive overflow to the outside.

[0030] Furthermore, a sealing end 103 is provided at the end of the first abutting frame 1 that is away from the second abutting frame 2 in the direction perpendicular to the light incident surface. The sealing end 103 protrudes toward the laminate 3 in the direction parallel to the light incident surface, so as to directly contact the first end face of the laminate 3 or indirectly contact the first end face of the laminate 3 through the connecting adhesive. The end face of the sealing end 103 is closer to the laminate 3 than the snap-fit ​​receiving portion 101 in the direction parallel to the light incident surface. Since the sealing end 103 is located at the edge of the first abutting frame 1, it needs to have sufficient length to ensure sealing connection. At the same time, the sealing end 103 does not protrude from the laminate 3 in the direction perpendicular to the light incident surface, so that the top of the assembled photovoltaic module can be reduced to reduce dust accumulation. At the same time, there is no blade-shaped protrusion in the original structure, which can also protect the laminate 3.

[0031] The photovoltaic module frame, through the cooperation of the first abutting frame 1 and the second abutting frame 2, allows the first abutting frame 1 and the second abutting frame 2 to respectively abut against the first end face of the laminate 3 perpendicular to the light incident surface and the second end face away from the light incident surface, thus completing the assembly of the photovoltaic module. Through the cooperation of the snap-fit ​​receiving part 101, the sealing end 103, and the adhesive cavity 106, the photovoltaic module frame can hold the cured adhesive, preventing delamination, and also has a sufficiently large adhesive space to cooperate with the snap-fit ​​receiving part 101 to hold the first end face of the laminate 3, reducing adhesive overflow to the outside, preventing poor adhesive performance, and solving problems such as adhesive overflow, insufficient adhesive, air bubbles, and frame detachment. This photovoltaic module frame retains the dust removal effect of a frameless A-side while enhancing the mechanical load-bearing capacity of the frame itself, protecting the laminate 3 and facilitating the assembly of the laminate 3.

[0032] Preferably, such as Figure 5 As shown, in this embodiment, the snap-fit ​​receiving portion 101 includes a protruding body 104 and at least one mating end 105. The protruding body 104 protrudes from the end face of the first abutting frame 1 toward the laminate 3. The mating end 105 is located at the end of the protruding body 104 perpendicular to the light incident surface. A cavity 106 for receiving adhesive is provided between the mating end 105 and the end face of the first abutting frame 1. Specifically, the snap-fit ​​receiving portion 101 can be formed into a T-shaped structure, with the vertical side of the T-shaped structure being the protruding body 104. In this embodiment, the protruding body 104 protrudes from the end face of the first abutting frame 1 toward the laminate 3, meaning the vertical side of the T-shaped structure extends laterally in the structure. In this embodiment, there are two mating ends 105, respectively located at the two ends of the protruding body 104 perpendicular to the light incident surface. The shape of the mating end 105 matches the shape of the groove wall of the snap-fit ​​groove 403. In the embodiment, the two mating ends 105 can be formed in the shape of an arc and a rectangle, respectively, but are not limited to this, and can also be cylindrical, triangular or other shapes that are easy to snap into place.

[0033] Preferably, such as Figure 5 As shown, in this embodiment, a first adhesive groove 102 is provided at the gap 301 between the snap-fit ​​receiving portion 101 and the laminate 3. During assembly, the adhesive in the gap 301 of the laminate 3 can be cleared through the first adhesive groove 102, thereby reducing or eliminating the need for edge trimming and adhesive removal after assembling the laminate 3. Adhesive is applied to the inside of the first abutting frame 1 and around the snap-fit ​​receiving portion 101, and the first end face of the laminate 3 is bonded to the first abutting frame 1 by the adhesive. Further, to ensure assembly sealing, the mating end 105 facing the end face of the laminate 3 is formed as, for example, a flat adhesive contact surface; or the mating end 105 facing the end face of the laminate 3 is formed as a concave-convex surface to increase the adhesion between the frame and the laminate 3.

[0034] Preferably, such as Figure 4 As shown, in this embodiment, the second abutting frame 2 is connected to the end of the first abutting frame 1 to form a complete frame. The second abutting frame 2, in conjunction with the first abutting frame 1, can limit the laminating component 3 in both directions parallel and perpendicular to the light incident surface, thereby meeting the assembly requirements of the photovoltaic module. The second abutting frame 2 is provided with multiple protrusions 201 protruding towards the laminating component 3. The protrusions 201 increase the thickness of the B-side, thus increasing the mechanical load on that side. Multiple protrusions 201 abut against the second end face of the laminating component 3. A second adhesive groove 202 is provided between adjacent protrusions 201. The second adhesive groove 202 can hold a large amount of adhesive and prevents the adhesive from overflowing during bonding. This reduces or eliminates the need for trimming and adhesive removal during lamination, allowing the laminating component 3 to be directly assembled with the frame. The second adhesive groove 202 is coated with adhesive, and the second end face of the laminating component 3 is bonded to the second abutting frame 2 using the adhesive.

[0035] Preferably, such as Figure 6 As shown, in this embodiment, the end face of the second abutting frame 2 facing the laminate 3 is formed as a convex surface 203, and a plurality of protrusions 201 are disposed on the convex surface 203, with the end face of each protrusion 201 abutting the laminate 3 located on the same horizontal plane. The convex surface 203 allows each second adhesive groove 202 to have a different amount of adhesive, thereby effectively reducing adhesive overflow. The fact that the end face of each protrusion 201 abutting the laminate 3 is located on the same horizontal plane ensures a horizontal and sealed connection at the second end face of the laminate 3.

[0036] Preferably, such as Figure 6 As shown, in this embodiment, a mounting groove for mounting the laminate 3 is formed between the first abutting frame 1 and the second abutting frame 2. The mounting groove is the groove portion of the L-shaped frame facing the laminate. The end of the second abutting frame away from the first abutting frame is inclined in a direction away from the mounting groove, so that the end of the second abutting frame is separated from the laminate. The end of the second abutting frame 2 away from the first abutting frame 1 is separated from the laminate 3 to form a separation area 204. The separation area 204 allows excess glue to overflow, and at the same time, it does not abut against the laminate 3. When the laminate 3 deforms downward due to gravity during use, it can also reduce the pressure on the laminate 3 in this area, prevent stress concentration, and avoid the laminate 3 from breaking.

[0037] Preferably, such as Figure 2 and Figure 3 As shown, in this embodiment, the photovoltaic module frame may further include a snap-fit ​​adhesive strip 4, which is snapped onto the snap-fit ​​receiving portion 101. In this embodiment, two assembly methods can be selected, the first being as follows: Figure 1As shown, without using the snap-fit ​​adhesive strip 4, when assembling the laminate 3, butyl adhesive strips or hot-melt butyl adhesive need to be applied to the gap 301 of the laminate 3. Slight overflow after lamination does not require trimming, and the overflowing adhesive can be contained in the first adhesive reservoir 102. The second method is as follows... Figure 2 As shown, a snap-fit ​​adhesive strip 4 is used, which is snapped into the snap-fit ​​receiving part 101. At this time, the frame is assembled after heating with a blowtorch. The gap 301 of the laminate 3 does not need to be covered with butyl adhesive strip or coated with hot melt butyl adhesive. The laminate 3 is directly encapsulated with POE / PVB, etc. Moreover, even if there is butyl adhesive encapsulation on the side of the laminate 3, it will not affect the assembly of the laminate 3 and the frame. At this time, the butyl adhesive on the edge of the laminate 3 can press the snap-fit ​​adhesive strip 4 to deform and bulge towards the first adhesive groove 102.

[0038] Preferably, such as Figure 3 As shown, in this embodiment, the snap-fit ​​adhesive strip 4 includes a snap-fit ​​end 401 and an abutment end 402 disposed back to back. The snap-fit ​​end 401 is provided with a snap-fit ​​groove 403, the shape of which is the same as the shape of the snap-fit ​​receiving portion 101, and the snap-fit ​​receiving portion 101 can be snapped into the snap-fit ​​groove 403. The abutment end 402 can be formed as a plane for abutting against the first end face of the laminate 3.

[0039] Preferably, such as Figure 1 As shown, in this embodiment, there are two assembly methods. The first method does not use the snap-fit ​​adhesive strip 4. The side of the snap-fit ​​receiving portion 101 and the second adhesive receiving groove 202 are both coated with adhesive. The first end face and the second end face of the laminate 3 respectively abut against the first abutting frame 1 and the second abutting frame 2. The adhesive at the gap of the laminate 3 is contained in the first adhesive receiving groove 102. Specifically, the first adhesive receiving groove 102 is formed as a semi-circular groove. The semi-circular groove is aligned with the gap 301 of the laminate 3. After the laminate 3 is assembled, it is not necessary to trim the butyl glue or POE overflowing from the glass gap after lamination. Butyl glue strips are applied or hot melt butyl glue is applied to the gap 301 around the laminate 3. The slight overflow after lamination does not need to be trimmed and is directly snapped into the first adhesive receiving groove 102. The height of the first adhesive receiving groove 102 and the gap 301 are automatically aligned. When the laminate 3 is not covered with butyl rubber strips or coated with hot melt butyl rubber around its four sides, hot melt butyl rubber can be applied to the first adhesive tank 102, with more applied to the four corners. After that, the frame is assembled to ensure good sealing. Any excess should be wiped clean. This assembly method can reduce the edge trimming and adhesive removal process and can ensure good sealing performance and mechanical load performance.

[0040] Preferably, such as Figure 2As shown, in this embodiment, the second method uses a snap-fit ​​adhesive strip 4 for assembly. When the laminate 3 is installed on the frame of the photovoltaic module, the snap-fit ​​adhesive strip 4 snaps into the snap-fit ​​receiving portion 101, the second receiving groove 202 is coated with adhesive, the first end face and the second end face of the laminate 3 abut against the first abutting frame 1 and the second abutting frame 2 respectively, and the snap-fit ​​adhesive strip 4 is partially received in the first receiving groove 102.

[0041] When using snap-fit ​​adhesive strip 4, apply the snap-fit ​​adhesive strip 4 to the inside of the first abutting frame 1 in advance, and then assemble the frame after heating with a blowtorch. There is no need to apply butyl adhesive strips or apply hot melt butyl adhesive at the laminate 3 and the gap 301. The laminate 3 can be directly encapsulated using POE or PVB, etc. The width of the adhesive film does not need secondary processing and cutting to fix the size, reducing the process difficulty and avoiding poor overlap between the adhesive film and butyl adhesive in the laminate 3.

[0042] Using the two assembly methods described above, a protrusion 201 is provided at the bottom overlap of the photovoltaic module frame and the laminate 3. The protrusion 201 increases the contact area between the laminate 3 and the connecting adhesive, reducing frame detachment and adhesive overflow. At the same time, a small amount of hot melt butyl adhesive can be applied in combination with conventional sealant to achieve a good water vapor barrier effect.

[0043] The photovoltaic module frame, through the cooperation of a first abutting frame and a second abutting frame, allows the first and second abutting frames to respectively abut against the first end face of the laminate perpendicular to the light incident surface and the second end face away from the light incident surface, thus completing the assembly of the photovoltaic module. Through the cooperation of the snap-fit ​​receiving part, the sealing end, and the adhesive cavity, the photovoltaic module frame can hold the cured adhesive, preventing delamination, and also has a sufficiently large adhesive space to cooperate with the snap-fit ​​receiving part to hold the first end face of the laminate, reducing adhesive overflow and preventing defects such as adhesive overflow, insufficient adhesive, air bubbles, and frame detachment. This photovoltaic module frame retains the dustproof effect of a frameless A-side while enhancing the frame's own mechanical load-bearing capacity, protecting the laminate and facilitating its assembly.

[0044] Furthermore, according to a second aspect of the present invention, a photovoltaic module is provided, the photovoltaic module including the photovoltaic module frame as described above.
