Technical Field

[0001] This utility model relates to the field of photovoltaic frame technology, and in particular to a photovoltaic composite material frame connection structure and frame. Background Technology

[0002] Photovoltaic composite material frame connection structure and frame are key components of photovoltaic modules. They are mainly used to fix and support the solar panels and realize the electrical connection between modules. They are made of composite material by compression molding, and the cross-section is mostly "U" or "L". The inner side is used to fix the solar panels. They are easy to install and disassemble and are suitable for modules that need maintenance or replacement.

[0003] Regarding the aforementioned technologies, the existing frame connection structure has the following drawbacks: the composite material has a low thermal conductivity, heat is easily accumulated locally, and the heat dissipation at the connection structure is poor, resulting in excessively high internal temperature of the module (especially under high light conditions), which leads to accelerated cell efficiency degradation, accelerated aging of adhesives, and shortened module life. Therefore, this utility model provides a photovoltaic composite material frame connection structure and frame. Utility Model Content

[0005] To achieve the above objectives, this application provides the following technical solution: a photovoltaic composite material frame connection structure and frame, including a connecting frame, the inner side of the connecting frame being hollowed out, the outer side of the connecting frame being coated with a silicone rubber insulating coating, and multiple heat dissipation components being provided on the inner side of the connecting frame; multiple heat conduction components are provided on the inner side of the connecting frame.

[0011] Preferably, the top of the elastic steel block is inclined, and the horizontal height of the side of the elastic steel block near the end of the connecting frame is lower than that of the other side.

[0012] In summary, the technical effects and advantages of this utility model are as follows:

[0013] In this invention, by setting up a heat-conducting component, the heat conduction path is reduced while ensuring connection strength. When the component temperature rises, the composite phase change material capsule absorbs heat and changes from solid to liquid, delaying local overheating. Furthermore, by setting up a heat dissipation component, heat from local hot spots (such as the contact area of ​​the connector) can be quickly discharged along the pipe axis, reducing thermal resistance.

[0022] Example: Reference Figure 1-4The diagram illustrates a photovoltaic composite material frame connection structure and frame, including a connecting frame 1. The inner side of the connecting frame 1 is hollowed out, which reduces overall weight and material costs while facilitating internal airflow and heat dissipation. The outer side of the connecting frame 1 is coated with a silicone rubber insulating coating, which effectively isolates current, prevents leakage, and ensures safe use. Multiple heat dissipation components are provided on the inner side of the connecting frame 1 to dissipate heat generated during photovoltaic module operation, preventing excessive temperature from affecting module performance and lifespan. Multiple heat-conducting components are also provided on the inner side of the connecting frame 1 for rapid heat conduction and improved heat dissipation efficiency. The heat dissipation components include multiple... The first heat dissipation groove 6 is located inside the connecting frame 1. Multiple stacked honeycomb tubes 10 are arranged within the first heat dissipation groove 6. The honeycomb tubes 10 have a large surface area, significantly increasing the contact area with air and improving heat dissipation efficiency. Thermally conductive silicone grease 9 is filled between the multiple honeycomb tubes 10 and the first heat dissipation groove 6. Its excellent thermal conductivity allows for rapid heat transfer from the connecting frame 1 to the honeycomb tubes 10, further enhancing the heat dissipation effect. The heat-conducting component includes multiple second heat dissipation grooves 8 located inside the connecting frame 1. Multiple grooves 11 are formed on the inner wall of the second heat dissipation grooves 8. Composite phase change material capsules 7 are placed within the grooves 11. The material capsule 7 undergoes a phase change when absorbing heat, enabling it to absorb and store a large amount of heat and stabilize the temperature of the connecting frame 1. Thermally conductive silicone sheets 12 are provided on the inner walls of the connecting frame 1, which can quickly conduct the heat generated by the photovoltaic module to the second heat dissipation groove 8, accelerating the heat transfer speed. Hollow grooves are opened on both sides of the inner walls of the connecting frame 1, and elastic steel sheets 4 are fixedly connected to the inner walls of the grooves. The elastic steel sheets 4 have good elastic deformation capabilities, providing a certain buffer and elastic support for the connecting frame 1, enhancing structural stability. A pair of elastic steel blocks 5 are fixedly connected to the outer sides of the elastic steel sheets 4, and a first frame 2 and a second frame 3 are respectively provided at both ends of the connecting frame 1. Both the inner sides of the first frame 2 and the second frame 3 are provided with slots 13 that are adapted to the elastic steel block 5. The elastic steel block 5 is made of nickel-titanium-based shape memory alloy. This alloy has a shape memory effect. After being deformed by external force, it can automatically restore its original shape when the temperature recovers, which facilitates the quick installation and disassembly of the first frame 2, the second frame 3 and the connecting frame 1. The top of the elastic steel block 5 is set with an inclined surface. The horizontal height of the side of the elastic steel block 5 near the end of the connecting frame 1 is lower than that of the other side. During installation, the inclined surface design allows the first frame 2 and the second frame 3 to engage with the connecting frame 1 more smoothly, improving installation efficiency and making the structure more stable after engagement.

[0023] The working principle of this utility model is as follows: The outer side of the connecting frame 1 is coated with a silicone rubber insulating coating to block the ion conduction path of electrochemical corrosion. The contact interface between the connecting frame 1 and the first frame 2 and the second frame 3 is filled with a thermally conductive silicone sheet 12, which reduces the heat conduction path and ensures the connection strength. A composite phase change material capsule 7 filled with paraffin-based phase change material is placed in the gap of the connecting frame 1. When the component temperature rises, the composite phase change material capsule 7 absorbs heat and changes from solid to liquid, delaying local overheating. Multiple honeycomb tubes 10 enhance the heat dissipation area and can quickly conduct the heat of local hot spots (such as the contact area of ​​the connector) along the tube axis, reducing thermal resistance. The air layer is eliminated by thermally conductive silicone grease 9, and the heat in the first frame 2, the second frame 3 and the connecting frame 1 is transferred to the honeycomb tubes 10 through contact heat conduction.
