Description

Technical Field

[0001] This application relates to the field of aluminum profile frame technology, and in particular to a heat-resistant and deformation-resistant solar panel aluminum frame. Background Technology

[0002] Currently, in the solar photovoltaic industry, solar aluminum frames are an important component of photovoltaic modules, playing a role in supporting, fixing, and protecting photovoltaic panels. With the continuous development of solar photovoltaic technology, the performance requirements for solar aluminum frames are also increasing.

[0003] Regarding the aforementioned technologies, existing traditional solar aluminum frames have some problems during use. On the one hand, under prolonged sunlight exposure, photovoltaic modules generate a large amount of heat, which accumulates in the aluminum frame and inside the module, causing the aluminum frame temperature to rise. Due to the thermal expansion and contraction effect, the aluminum frame is prone to deformation, thus affecting the overall structural stability of the photovoltaic module. On the other hand, the existing aluminum frame heat dissipation structure design is unreasonable, with narrow and unevenly distributed heat dissipation channels, making it difficult for heat to be quickly dissipated into the external environment, further exacerbating the deformation problem of the aluminum frame. Utility Model Content

[0004] The purpose of this application is to provide a heat-resistant and deformation-resistant aluminum solar cell frame, which has the advantages of heat resistance and deformation resistance, and solves the problems mentioned in the background art.

[0005] This application provides a heat-resistant and deformation-resistant solar aluminum frame with the following technical solution: it includes a lower frame, the top of which overlaps with an upper frame. A plurality of columns are fixedly connected to the top of the lower frame, and ring blocks are fixedly connected to the surfaces of each of the columns. Ring plates are fitted onto the surfaces of each of the columns, and solar panels are fixedly installed on the sides of each of the ring plates. Positioning holes are provided at the top of each of the columns. A plurality of limiting posts are fixedly connected to the bottom of the upper frame, and fastening blocks are fixedly connected to the surfaces of each of the limiting posts. The limiting posts are inserted into the positioning holes, and the ring blocks overlap with the ring plates.

[0006] By adopting the above technical solution, and by setting up an upper frame and a lower frame, the column and the limiting column can be inserted and matched (positioning hole and limiting column), and combined with the overlap of the ring block and the ring plate, a detachable and stable connection can be formed, which facilitates the installation and maintenance of the solar panel. At the same time, it avoids deformation and misalignment caused by thermal expansion and contraction. Furthermore, due to the above design structure, a gap will be formed between the upper frame, the lower frame and the solar panel. In this way, the heat generated by the solar panel during operation cannot directly burn the upper frame and the lower frame, thus achieving the purpose of heat protection and deformation prevention for the upper frame and the lower frame.

[0007] Preferably, the bottom of the lower frame is fixedly connected to two mounting blocks, and the sides of the two mounting blocks are provided with sliding grooves.

[0008] By adopting the above technical solution and setting up mounting blocks and sliding grooves, the effect of sliding adjustment between the frame and the external bracket can be achieved, while adapting to the positioning requirements of different installation scenarios and improving construction flexibility.

[0009] Preferably, a welding plate is fixedly connected to the bottom of the lower frame.

[0010] By adopting the above technical solution, the welding plate provides additional fixing points for the frame, which can be connected to the external support structure by welding, thereby enhancing the overall installation stability and making it suitable for scenarios requiring high-strength fixing.

[0011] Preferably, the top of the upper frame has two handle slots, and the fastening block is made of carbon fiber prepreg layer.

[0012] By adopting the above technical solution, the handle groove is designed to provide a gripping effect during handling and installation, reducing the difficulty of manual operation and improving construction efficiency. In addition, the fastening block uses a carbon fiber prepreg layer, which has both high strength and low thermal conductivity, avoiding local high temperature caused by heat conduction in the metal material, while also reducing the weight of the frame.

[0013] Preferably, the lower frame and the upper frame are provided with a number of heat dissipation holes on their sides, and a heat insulation cavity is provided between the upper frame, the lower frame and the solar panel.

[0014] By adopting the above technical solution, the setting of heat dissipation holes and heat insulation cavity can enable the heat dissipation holes opened on the sides of the upper and lower frames, together with the heat insulation cavity between the upper and lower frames and the solar panel, to form an air convection channel, quickly dissipate the heat generated by the solar panel when it is working, avoid local high temperature causing frame deformation or photovoltaic module efficiency degradation, and at the same time, the heat insulation cavity can also facilitate the formation of a drainage channel for rainwater on rainy days, preventing rainwater from staying on the solar panel for too long.

[0015] Preferably, a number of fixing blocks are fixedly connected to the side of the lower frame and the side of the upper frame, and screws are threadedly connected to the inside of the fixing blocks.

[0016] By adopting the above technical solution, and by setting fixing blocks and screws, the fixing blocks and screws on the sides of the upper frame and the lower frame can be fixed to form a multi-point locking structure, which improves the wind pressure resistance and vibration resistance of the overall frame and is suitable for complex outdoor environments.

[0017] Preferably, the lower frame has a groove at its top, and the upper frame has a protrusion fixedly connected to its bottom, the protrusion being engaged inside the groove.

[0018] By adopting the above technical solution, the snap-fit ​​design of the groove and the convex frame further enhances the sealing performance and structural rigidity of the upper and lower frames, preventing displacement under external force.

[0019] Preferably, the surface of the lower frame is coated with a ceramic heat-insulating primer, and the surface of the upper frame is provided with an ultra-weather-resistant and UV-resistant coating.

[0020] By adopting the above technical solution, the ceramic heat-insulating primer on the surface of the lower frame has low thermal conductivity, which blocks external heat from being conducted to the frame. The ultra-weather-resistant and UV-resistant coating of the upper frame can resist ultraviolet aging and reduce the temperature rise caused by direct sunlight, thus extending the service life of the frame.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] This heat-resistant and deformation-resistant aluminum solar panel frame, through the setting of an upper frame and a lower frame, allows the column and the limiting column to be inserted and matched (positioning hole and limiting column), combined with the overlap of the ring block and the ring plate, to form a detachable and stable connection, which facilitates the installation and maintenance of the solar panel, and avoids deformation and misalignment caused by thermal expansion and contraction. Furthermore, due to the above design structure, a gap is formed between the upper frame, the lower frame and the solar panel. In this way, the heat generated by the solar panel during operation cannot directly burn the upper frame and the lower frame, thus achieving the purpose of heat-resistant and deformation-resistant protection for the upper frame and the lower frame.

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 7 This application will be described in further detail below.

[0033] Example 1: A heat-resistant and deformation-resistant aluminum frame for solar panels, as shown in the following example. Figure 1 , Figure 2 and Figure 4 The system includes a lower frame 1, with an upper frame 2 overlapping the top of the lower frame 1. Several columns 14 are fixedly connected to the top of the lower frame 1. Ring blocks 15 are fixedly connected to the surfaces of each column 14. Ring plates 11 are fitted onto the surfaces of each column 14. Solar panels 3 are fixedly installed on the sides of each ring plate 11. Positioning holes 16 are provided at the top of each column 14. Several limiting posts 12 are fixedly connected to the bottom of the upper frame 2. Fastening blocks 13 are fixedly connected to the surfaces of each limiting post 12. The limiting posts 12 are inserted into the positioning holes 16. The ring blocks 15 overlap with the ring plates 11. The system is designed to... The upper frame 2 and the lower frame 1 allow the column 14 and the limiting column 12 to be inserted and matched (positioning hole 16 and limiting column 12). Combined with the overlap of the ring block 15 and the ring plate 11, a detachable and stable connection is formed, which facilitates the installation and maintenance of the solar panel 3. At the same time, it avoids deformation and misalignment caused by thermal expansion and contraction. Furthermore, due to the above design structure, a gap is formed between the upper frame 2, the lower frame 1 and the solar panel 3. In this way, the heat generated by the solar panel 3 during operation cannot directly burn the upper frame 2 and the lower frame 1, thus achieving the purpose of heat protection and deformation prevention for the upper frame 2 and the lower frame 1.

[0034] Please see Figure 1 The bottom of the lower frame 1 is fixedly connected to two mounting blocks 4. The sides of the two mounting blocks 4 are provided with sliding grooves 5. By setting the mounting blocks 4 and sliding grooves 5, the effect of sliding adjustment between the frame and the external bracket can be achieved. At the same time, it can adapt to the positioning requirements of different installation scenarios and improve construction flexibility. The bottom of the lower frame 1 is fixedly connected to a welding plate 6. The setting of the welding plate 6 provides additional fixing points for the frame. It can be connected to the external support structure by welding, which enhances the overall installation firmness and is suitable for scenarios that require high-strength fixing.

[0035] Please see Figure 1 , Figure 3 and Figure 7 The top of the upper frame 2 has two handle grooves 7. The fastening block 13 is made of carbon fiber prepreg 18. The handle grooves 7 provide a gripping effect during handling and installation, reducing the difficulty of manual operation and improving construction efficiency. The fastening block 13, made of carbon fiber prepreg 18, has both high strength and low thermal conductivity, avoiding localized high temperatures caused by heat conduction in the metal material, while also reducing the weight of the frame. Several heat dissipation holes 8 are provided on the sides of both the lower frame 1 and the upper frame 2. A heat insulation cavity 22 is provided between the solar panel 3 and the heat dissipation hole 8. The heat dissipation hole 8 on the side of the upper frame 2 and the lower frame 1, together with the heat insulation cavity 22 between the upper frame 2, the lower frame 1 and the solar panel 3, form an air convection channel to quickly dissipate the heat generated by the solar panel 3 when it is working, and avoid local high temperature causing frame deformation or photovoltaic module efficiency degradation. At the same time, the heat insulation cavity 22 also facilitates the drainage channel for rainwater on rainy days, preventing rainwater from staying on the solar panel 3 for too long.

[0036] Please see Figure 1 , Figure 2 , Figure 5 and Figure 6 Several fixing blocks 9 are fixedly connected to the sides of both the lower frame 1 and the upper frame 2. Each of the fixing blocks 9 has a screw 10 threaded into its interior. By using the fixing blocks 9 and screws 10, the upper frame 2 and the fixing blocks 9 and screws 10 on the sides of the lower frame 1 can be fixed together, forming a multi-point locking structure. This improves the overall frame's wind pressure and vibration resistance, making it suitable for complex outdoor environments. A groove 17 is provided on the top of the lower frame 1, and a protruding frame 19 is fixedly connected to the bottom of the upper frame 2. The protruding frame 19 engages with the groove 17. The interlocking design of the groove 17 and the convex frame 19 further enhances the sealing and structural rigidity of the upper frame 2 and the lower frame 1, preventing displacement under external force. The surface of the lower frame 1 is coated with ceramic heat-insulating primer 20, and the surface of the upper frame 2 is provided with ultra-weather-resistant and UV-resistant coating 21. The ceramic heat-insulating primer 20 on the surface of the lower frame 1 has low thermal conductivity, blocking external heat from being conducted to the frame. The ultra-weather-resistant and UV-resistant coating 21 on the upper frame 2 can resist ultraviolet aging and reduce the temperature rise caused by direct sunlight, extending the service life of the frame.

[0037] The implementation principle of this application embodiment is as follows: First, during installation, the solar panel 3 is first sleeved onto the column 14 through the ring plate 11. Initial positioning is achieved by the overlap of the ring block 15 and the ring plate 11. Then, holding the handle groove 7, the limiting post 12 of the upper frame 2 is aligned with the positioning hole 16 at the top of the column 14 of the lower frame 1 and inserted. At the same time, the protruding frame 19 at the bottom of the upper frame 2 is engaged in the groove 17 at the top of the lower frame 1, completing the initial splicing of the frame. Subsequently, the screws 10 in the fixing blocks 9 on the sides of the upper frame 2 and the lower frame 1 are tightened to form a multi-point locking structure, which enhances the overall rigidity. The mounting block 4 at the bottom can slide along the sliding groove 5 of the external bracket to adjust its position. To meet the needs of different installation scenarios, for scenarios requiring high-strength fixation, the welding plate 6 can be welded to the external support structure to achieve stable installation. Then, after the solar panel 3 is put into operation, the heat generated will raise the ambient air temperature. At this time, the gap between the upper frame 2, the lower frame 1 and the solar panel 3 prevents the heat from being directly conducted to the frame, avoiding scorching. At the same time, the heat dissipation holes 8 on the side of the frame and the heat insulation cavity 22 form an air convection channel. Hot air rises and is discharged from the heat dissipation holes 8, while cold air enters from below to replenish it, quickly carrying away the heat generated by the solar panel 3 and reducing the local temperature. The ceramic heat insulation primer 20 on the surface of the lower frame 1 further blocks the heat. External heat is transferred to the frame. The ultra-weather-resistant and UV-resistant coating 21 of the upper frame 2 reduces the temperature rise caused by direct sunlight. Multiple measures work together to control the frame temperature and prevent deformation or reduction in photovoltaic module efficiency due to high temperature. Then, in complex outdoor environments, the multi-point locking structure of the fixing block 9 and screw 10, combined with the snap-fit ​​design of the groove 17 of the convex frame 19, effectively resists wind pressure and vibration and maintains the stability of the frame. The fastening block 13 uses a carbon fiber prepreg layer 18, which has both high strength and low thermal conductivity, ensuring the stability of the connection of the limiting column 12 and avoiding local high temperature caused by heat conduction. When the ambient temperature changes and the solar panel 3 expands and contracts due to heat, the column 14 and the limiting column... The interlocking of 12 and the overlapping structure of the ring block 15 and the ring plate 11 allow the solar panel 3 to freely expand and contract within a certain range, preventing thermal stress concentration from causing deformation and misalignment, and maintaining the overall structural stability. Finally, the heat insulation cavity 22 not only dissipates heat but also acts as a rainwater drainage channel. During rainy days, rainwater can be quickly discharged through the heat insulation cavity 22 to prevent water accumulation from corroding the solar panel 3 and the frame. When maintenance is required, simply unscrew the screws 10 of the side fixing block 9 to disassemble the upper frame 2. Through the overlapping structure of the ring plate 11 and the ring block 15, the solar panel 3 can be easily inspected or replaced, achieving convenient maintenance and ensuring the long-term stable operation of the photovoltaic system.
