Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy plate technology, specifically to a fatigue-resistant aluminum alloy plate structure. Background Technology

[0002] Aluminum alloy sheet structures are frames or integral systems built primarily of aluminum alloy sheets. Aluminum alloy sheets offer advantages such as light weight, high strength, and corrosion resistance. They come in various structural forms, and can be manufactured into flat panels for building curtain walls, vehicle shells, etc., or processed into irregular shapes for use in aerospace components such as fuselages and wings. This effectively reduces overall weight while maintaining structural strength, thus improving performance and efficiency. To further enhance the load-bearing capacity and structural stability of aluminum alloy plates, a common engineering design approach is to install a grid-like reinforcing rib on the inner side of the aluminum alloy plate. This design, by constructing a crisscrossing rib network, can effectively distribute external loads, significantly enhance the bending and torsional resistance of the plate, and meet the needs of use under complex working conditions. However, when aluminum alloy plates are subjected to continuous high temperatures (above 120°C), the mesh-like reinforcing ribs divide the space, hindering air circulation, making it difficult for heat to dissipate and causing a large accumulation, which reduces its mechanical properties, especially its fatigue resistance, accelerates the propagation of fatigue cracks, and shortens the life of the plate. Therefore, a fatigue-resistant aluminum alloy plate structure is proposed to address the above problems. Utility Model Content

[0017] As a further implementation of this solution, the inner sides of both the longitudinal ventilation hole 22 and the transverse ventilation hole 23 are arc-shaped. The inner sides of both the longitudinal ventilation hole 22 and the transverse ventilation hole 23 are connected to the inner side of the heat dissipation cavity 24. The angle between the transverse ventilation holes 23 and the transverse ventilation holes 23 is 90°, allowing air to flow in both the X and Y axes, effectively preventing heat from accumulating in the mesh-like reinforcing ribs 21, ensuring that heat can be dissipated quickly, and extending the overall service life of the aluminum alloy plate. As a further implementation of this solution, multiple heat dissipation communication cavities 24 are provided, and the multiple heat dissipation communication cavities 24 are arranged in a square array. The conductive plate 26 is located at the top of the inner side of the heat dissipation communication cavity 24. The conductive plate 26 is engaged with the heat dissipation communication cavity 24 to ensure that the conductive plate 26 can be stably installed in the heat dissipation communication cavity 24 and to ensure the stability of heat conduction. As a further implementation of this solution, the number of conductive plates 26 is the same as the number of heat dissipation connecting cavities 24. Four first heat dissipation slots 28 are provided on the outer side of the conductive plates 26. The inner side of the first heat dissipation slots 28 has an arc-shaped structure. Connecting slots 29 are provided in the four corner areas of the conductive plates 26. The inner side of the connecting slots 29 has an arc-shaped structure. The inner side of the connecting slots 29 is connected to the inner side of the heat dissipation connecting cavity 24, which is conducive to air flow and further improves the heat dissipation effect. As a further implementation of this solution, the top of the connecting column 252 is a planar structure, the connecting column 252 and the transmission rod 254 are located on the same central axis, and the top of the transmission rod 254 extends to the upper surface of the transmission plate 26, which improves the stability of the aluminum alloy plate structure when subjected to external forces. As a further implementation of this solution, the connecting plate 251 is shaped like a "+", and a second heat dissipation groove 256 is provided on the lower surface of the connecting plate 251 to increase the heat dissipation area. There are four arc-shaped heat dissipation grooves 253 on the outer side of each connecting post 252. The four arc-shaped heat dissipation grooves 253 are arranged in a circle. The inner side of the arc-shaped heat dissipation grooves 253 is connected to the inner side of the heat dissipation hole 255. The heat dissipation hole 255 extends to the bottom of the connecting plate 251 to promote airflow at the connection between the connecting post 252 and the connecting plate 251 and accelerate heat dissipation.

[0018] Workflow: After the upper aluminum alloy substrate 3 generates heat, it is transferred to the conductive plate 26 through the fixing plate 27. The conductive plate 26 not only performs the function of heat conduction, but also enhances the structural strength of the upper aluminum alloy substrate 3, thereby effectively improving its fatigue resistance. The first heat dissipation groove 28 and the corner connecting groove 29 on the outer side of the conductive plate 26 increase the heat dissipation area. The grid-like reinforcing rib 21 serves as the main support structure. Multiple conductive plates 26 transfer heat to the corresponding conductive rods 254. The conductive rods 254 are key components connecting the fixing plate 27 and the connecting post 252. At the same time, they can also conduct heat to the connecting post 252. The arc-shaped heat dissipation groove 253 on the surface of the connecting post 252 and the heat dissipation holes 255 on the upper surface of the second heat dissipation groove 256 can promote the connection post 252. The airflow at the connection point with the connecting plate 251 further promotes the heat dissipation effect of the connecting column 252. The second heat dissipation groove 256 can increase the heat dissipation area of ​​the lower surface of the connecting plate 251. The setting of the connecting plate 251 not only enhances the structural strength of the inner side of the heat dissipation connecting cavity 24, but also can transfer heat to the grid-shaped reinforcing rib 21 to expand the heat transfer area. In the heat dissipation process, the grid-shaped reinforcing rib 21 can promote the airflow inside it through the longitudinal ventilation holes 22 and the transverse ventilation holes 23 set on the upper and lower surfaces. The air can smoothly enter the heat dissipation connecting cavity 24. The setting of the longitudinal ventilation holes 22 and the transverse ventilation holes 23 allows the air to dissipate heat in both the X-axis and Y-axis directions, effectively preventing heat from accumulating in the grid-shaped reinforcing rib 21 and extending its service life.
