Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] One embodiment of this utility model is as follows: Figure 1 , Figure 2 and Figure 5 As shown, the solar frame is spliced ​​together from four aluminum profiles installed vertically in pairs. The aluminum profiles include a frame body 10, which is made of high-strength aluminum alloy. The frame body 10 includes a side plate 11 and a first pressure plate 12, a second pressure plate 13, and a bottom plate 14 located on one side of the side plate 11. The first pressure plate 12 and the second pressure plate 13 are arranged vertically on one side of the bottom plate 14. An angle bracket mounting cavity 15 is provided between the second pressure plate 13 and the bottom plate 14. A heat insulation cavity 16 is provided inside the frame body 10, and the heat insulation cavity 16 is filled with phase change material. A water-guiding structure 20 is provided on the surface of the frame body 10. The surface of the frame body 10 is coated with a weather-resistant coating. By providing a heat insulation cavity inside the frame body and filling the heat insulation cavity with phase change material, the characteristic of phase change material to absorb or release a large amount of heat during the phase change process can be utilized to effectively reduce the thermal deformation of the frame in high-temperature environments, improve the stability and service life of the solar module, and the structure is simple and easy to process.

[0021] The heat insulation cavity 16 includes a first heat insulation cavity 161 disposed between the corner bracket mounting cavity 15 and the side plate 11, and a second heat insulation cavity 162 disposed between the corner bracket mounting cavity 15 and the bottom plate 14.

[0022] Because the base plate is long, in order to ensure structural strength, the second heat insulation cavity 162 is divided into several cavities of equal width by a partition. After the second heat insulation cavity 162 and the first heat insulation cavity 161 are filled with phase change material, they are sealed at the end face by welding.

[0023] In a preferred embodiment of this application, the phase change material is paraffin wax, which is filled into the first insulation cavity and the second insulation cavity and then sealed at the rear end.

[0024] like Figure 3 As shown, heat dissipation groove structures 17 are provided on the side of the side plate 11 away from the first heat insulation cavity 161 and on the side of the bottom plate 14 away from the second heat insulation cavity 162. The cross-sectional shape of the heat dissipation groove structure 17 is a right trapezoid and is integrally formed with the frame body 10. The heat dissipation groove structures 17 are close to the heat insulation cavity 16, which can increase the heat dissipation area of ​​the frame, further improve the heat dissipation performance of the frame, effectively reduce the frame temperature, and prevent thermal deformation.

[0025] like Figure 4As shown, the water guiding structure 20 includes a water guiding groove 21 on the surface of the first pressure plate 12 and the side plate 11. The bottom of the water guiding groove 21 on the surface of the side plate 11 is connected to the third heat insulation cavity 163 inside the first heat insulation cavity 161 through the inclined interface 22. The third heat insulation cavity 163 is a semi-enclosed cavity with two baffles connected to the water guiding groove 21 inside the first heat insulation cavity 161. The water guiding structure can guide the water accumulated on the surface of the solar module from the water guiding groove to the third heat insulation cavity. Water, as a phase change material, can also absorb a lot of heat during the phase change process, thereby reducing the frame temperature.

[0026] The working principle of this embodiment is as follows: When the solar module operates in a high-temperature environment, external heat is transferred to the interior through the frame body. When the temperature reaches the melting point of paraffin wax, the paraffin wax absorbs a large amount of heat and undergoes a phase change, changing from a solid to a liquid state, thereby effectively reducing the temperature of the frame body and preventing it from undergoing thermal deformation.

[0027] Several points need to be clarified: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly, and can refer to mechanical or electrical connections, or internal connections between two components, or direct connections. Terms such as "upper," "lower," "left," and "right" are only used to indicate relative positional relationships, and the relative positional relationships may change when the absolute position of the described objects changes. Second, in this document, relational terms such as "first" and "second" are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.

[0028] The above examples are merely illustrative of this utility model and do not constitute a limitation on the scope of protection of this utility model. All designs that are the same as or similar to this utility model are within the scope of protection of this utility model.
