Description

Technical Field

[0001] The utility model relates to the field of photovoltaic component manufacturing, in particular to a photovoltaic component frame and a photovoltaic component capable of reducing dust accumulation. Background Art

[0002] With the advancement of photovoltaic technology, the efficiency of photovoltaic modules has been continuously improved. However, when installed at a small angle on the roof, photovoltaic modules often face dust accumulation problems and are difficult to clean. Figure 3 and Figure 4 As shown, the height H1 of the A surface of the conventional photovoltaic module frame is usually between 2.5mm and 3.0mm, and the width L1 is between 10mm and 12mm. In the application scenario of small-angle installation, the dust accumulation width M1 on the surface of the photovoltaic module is theoretically large, which may cause the laminate to be blocked by dust accumulation, thereby forming hot spots in the working state, accelerating material aging, and causing a large loss of power generation.

[0003] In order to solve this problem, full-screen photovoltaic modules were proposed, but they are expensive, have complex manufacturing processes, are not compatible with conventional frame assembly machines, and have poor versatility, which limits their application in various scenarios. Utility Model Content

[0004] The purpose of the utility model is to provide a photovoltaic module frame and photovoltaic module with reduced dust accumulation, so as to solve the problem that the width of dust accumulation formed by the laminated parts on the A surface of the conventional photovoltaic module frame in the prior art is large when the frame is installed at a small angle, which affects the power generation efficiency of the photovoltaic module. The manufacturing process is simple, and it is compatible with the existing conventional frame assembly machine, and the manufacturing cost is lower than that of the full-screen photovoltaic module frame.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A photovoltaic module frame with reduced dust accumulation, used for installing a laminate, the photovoltaic module frame comprising:

[0007] Side B;

[0008] Side A, the thickness H2 of the side A is 1 mm to 1.2 mm, and the width L2 of the side A is 5 mm to 8 mm;

[0009] Side C, arranged perpendicularly to side A at two ends of side B, and side A is located above side C;

[0010] The bonding edge is perpendicular to the B edge and is located between the A edge and the C edge. The A edge, the B edge, and the bonding edge enclose a mounting groove. In the width direction of the bonding edge, the top surface of the bonding edge is inclined downward from the middle toward the B edge to form a glue storage portion, and the top surface of the bonding edge is inclined downward from the middle away from the B edge to form an adapting portion.

[0011] The D side has two ends which are respectively perpendicular to the C side and the bonding side, and the B side, the C side, the bonding side and the D side enclose a hollow cavity;

[0012] A limiting support is arranged in the middle of the B side of the installation groove and is placed in the installation groove to support the laminate.

[0013] In some embodiments, the width L3 of the limiting support is 0.5 mm to 1 mm, and the height H3 of the limiting support is 1.2 mm to 2 mm.

[0014] In some embodiments, the thickness D1 of the bonding edge is 1.2 mm to 1.6 mm.

[0015] In some embodiments, the width L2 of the A side is smaller than the distance L5 between the outer side walls of the B side and the D side.

[0016] In some embodiments, the width L4 of the bonding edge is greater than the distance L5 between the outer side walls of the B edge and the D edge.

[0017] In some embodiments, the width L6 of the C edge is greater than the width L4 of the bonding edge.

[0018] In some embodiments, the thickness D2 of the B side is 1.3 mm to 1.6 mm.

[0019] In some embodiments, the thickness D3 of the C side is 1.4 mm to 1.6 mm.

[0020] In some embodiments, the thickness D4 of the D side is 1.3 mm to 1.6 mm.

[0021] The present application also protects a photovoltaic module, including the photovoltaic module frame as described above.

[0022] Due to the application of the above technical solution, the beneficial effects of the present application compared with the prior art are:

[0023] The photovoltaic module frame for reducing dust accumulation of the present application retains the design of the A side to adapt to the conventional frame assembly machine. Compared with the preparation of the full-screen photovoltaic module frame, its manufacturing cost is low and the process is simple. Under the premise of ensuring strength, the thickness and width range of the A side are controlled, thereby reducing the dust accumulation width M2 formed on the surface of the laminate when the A side of the photovoltaic module frame is installed at a small angle, which can reduce the risk of hot spots, slow down the aging of materials, reduce the use of materials, reduce costs, and ensure the durability and reliability of the photovoltaic module frame in production and use, and improve the photoelectric conversion efficiency of photovoltaic modules.

[0024] At the same time, in the installation groove, a limited support is set in the middle of the B side of the installation groove to provide support for the laminate, avoid the situation where the A side cannot effectively cover the laminate due to the laminate shifting in a certain direction, and improve the installation quality.

[0025] In addition, considering that the thickness of the laminate is not exactly the same at every location, the actual thickness of the laminate gradually becomes thicker towards the inside within a range of about 20 mm from the outermost edge. In the present application, the top surface of the bonding edge is tilted downward away from the B edge in the width direction to form an adapter portion to better fit the surface of the laminate and improve assembly stability.

[0026] The top surface of the bonding edge is tilted downward toward the B side in the width direction to form a glue storage portion for storing silicone. Before assembling the frame, the silicone can be directly injected into the middle of the top surface of the bonding edge and the glue storage portion through the glue head of the frame assembly machine. The glue injection is convenient and fast and easy to adjust. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] A photovoltaic module according to one embodiment of the present application includes a laminate and a photovoltaic module frame for installing the laminate and reducing dust accumulation. The photovoltaic module frame can reduce the dust accumulation width formed between the A side and the laminate in a small-angle installation scenario, thereby reducing dust accumulation on the surface of the laminate, thereby improving the photoelectric conversion efficiency of the photovoltaic module.

[0041] See also Figure 1 and Figure 2 The photovoltaic module frame includes a B side 2, an A side 1, a C side 3, a D side 4, a bonding side 5 and a limit support 6. The A side 1, the B side 2 and the bonding side 5 are enclosed to form a mounting groove 9, and the B side 2, the C side 3, the bonding side 5 and the D side 4 are enclosed to form a hollow cavity 10. The mounting groove 9 is used to accommodate the edge of the laminate 100 and is bonded to the edge of the laminate 100 through silicone. The hollow cavity 10 is used to install the frame corner code (not shown), and the C side 3 is provided with a bolt mounting hole (not shown), which is a conventional structure.

[0042] Specifically, the thickness H2 of the A side 1 is 1 mm to 1.2 mm, and the width L2 of the A side 1 is 5 mm to 8 mm.

[0043] Combination Figure 2 and Figure 4 When other conditions are the same, the dust accumulation width M2 of the photovoltaic module frame of the present application is significantly reduced compared to the dust accumulation width M1 of the conventional photovoltaic module frame.

[0044] The C edge 3 is arranged perpendicularly to the A edge 1 at both ends of the B edge 2, and the A edge 1 is located above the C edge 3. The bonding edge 5 is perpendicular to the B edge 2 and is located between the A edge 1 and the C edge 3.

[0045] In the width direction of the bonding edge 5, the top surface of the bonding edge 5 is inclined downward from the middle toward the B edge 2 to form a glue storage portion 7, and the top surface of the bonding edge 5 is inclined downward from the middle away from the B edge 2 to form an adapting portion 8. The two ends of the D edge 4 are perpendicular to the C edge 3 and the bonding edge 5 respectively.

[0051] In some embodiments, the thickness D3 of the C-side 3 is 1.4 mm to 1.6 mm.

[0052] In some embodiments, the thickness D4 of the D side 4 is 1.3 mm to 1.6 mm.

[0053] The limiting support 6 is arranged at the middle of the B side 2 of the installation groove 9 and is placed in the installation groove 9 for supporting the laminate 100 .

[0054] In some embodiments, the width L3 of the limiting support 6 is 0.5 mm to 1 mm, and the height H3 of the limiting support 6 is 1.2 mm to 2 mm.

[0055] Before framing, silicone is directly injected into the top surface of the bonding edge 5 in the middle of the width direction and the glue storage part 7 through the glue head of the framing machine. After the gluing is completed, it is framed with the laminate 100. The framing process is the same as that of a conventional photovoltaic module frame and will not be described here.

[0056] At this time, the silicone will be filled in the semi-enclosed area formed by the laminate 100, the A edge 1, the B edge 2 and the top surface of the bonding edge 5, and the top surface of the bonding edge 5 will be completely covered by the silicone. Under the action of the limiting support 6, a small amount of silicone will be filled into the inner side of the A edge 1.

[0060] In addition, considering that the thickness of the laminate is not exactly the same at every location, the actual thickness of the laminate gradually becomes thicker towards the inside within a range of about 20 mm from the outermost edge. In the present application, the top surface of the bonding edge is tilted downward away from the B edge in the width direction to form an adapter portion to better fit the surface of the laminate and improve assembly stability.

[0061] The top surface of the bonding edge is tilted downward toward the B side in the width direction to form a glue storage portion for storing silicone. Before assembling the frame, the silicone can be directly injected into the middle of the top surface of the bonding edge and the glue storage portion through the glue head of the frame assembly machine.
