[0002] In the display field, both backlight modules for liquid crystal displays (LCDs) and LED displays rely heavily on light-emitting modules. For LCDs, the backlight module provides a uniform and bright light source to ensure the LCD panel can display images correctly. For LED displays, the light-emitting module is the basic unit that makes up the display. By controlling the light-emitting state of the LEDs in each module, high-resolution, high-contrast, and color-rich image and video displays can be achieved, making them widely used in various scenarios.

[0003] The aluminum profiles of existing light-emitting modules not only serve as supports and connections but also as heat dissipation materials. Since aluminum profiles are generally made of solid or hollow materials, hollow aluminum profiles are difficult to have high mechanical strength and have poor load-bearing capacity, while solid aluminum profiles are heavier, more expensive, and have poor heat dissipation, making it difficult to transfer the heat generated by the light-emitting module in time, thus affecting the service life of the light-emitting module.

[0021] This specific embodiment is a heat dissipation structure for an aluminum alloy profile of a light-emitting module, and its structural schematic diagram is shown below. Figures 1-3As shown, the structure includes a rod 1, which is made of 6303 aluminum alloy. The main components of 6303 aluminum alloy include aluminum, magnesium, and silicon, with aluminum being the main component, accounting for more than 98%. The magnesium content is between 0.45% and 0.9%, which can improve the hardness and heat resistance of the aluminum alloy, while also increasing the strength and wear resistance of the alloy. The silicon content is between 0.2% and 0.6%, which can improve the fluidity and corrosion resistance of the aluminum alloy, while also increasing the strength and hardness of the alloy. The cross-section of the rod 1 includes a rectangular main body 2. U-shaped grooves 3 are opened on both the left and right sides of the main body 2. L-shaped grooves 4 are opened on both the left and right sides of the upper surface of the main body 2. Multiple heat dissipation cavities 5 are opened on the main body 2 from left to right, and the heat dissipation cavities 5 penetrate through the front and rear sides of the rod 1.

[0022] like Figure 1 and Figure 2 As shown: In this embodiment, the U-shaped groove 3 is located at the bottom of the left and right sides of the main body 2, and the U-shaped groove 3 penetrates the front and rear sides of the rod 1; the U-shaped groove 3 can increase the area of ​​the outer surface of the main body 2, so that the outer side can better contact the air and improve the heat dissipation effect of the rod 1.

[0023] like Figure 2 and Figure 3 As shown: In this embodiment, two L-shaped grooves 4 are symmetrically arranged on the left and right sides of the main body 2, and the L-shaped grooves 4 penetrate through the front and rear sides of the rod 1; the L-shaped grooves 4 can increase the area of ​​the outer surface of the main body 2, better allow the outer side to contact the air, and improve the heat dissipation effect of the rod 1.

[0024] like Figure 1 and Figure 3 As shown: In this embodiment, there are 7 heat dissipation cavities 5 with their lower surfaces flush. The distance between the heat dissipation cavity 5 and the upper surface of the main body 2 is greater than the distance between the heat dissipation cavity 5 and the lower surface of the main body 2. In this way, the main body 2 is the heat source, and the heat dissipation cavity 5 not only reduces the weight and manufacturing cost, but also makes the rod 1 as a whole have high mechanical strength.

[0025] like Figure 2 and Figure 3 As shown: In this embodiment, the heat dissipation cavity 5 has a rectangular cross-section, and the horizontal width of the heat dissipation cavity 5 is smaller than its vertical width; the heat dissipation cavity 5 includes five first through holes 501 and two second through holes 502. The height of the first through holes 501 is greater than the height of the second through holes 502. The five first through holes 501 are located in the middle of the main body 2, and the two second through holes 502 are located on the left and right sides of the five first through holes 501; the smaller second through holes 502 are set on the left and right sides of the rod 1, so as not to affect the mechanical strength of the side of the rod 1.

[0026] In this embodiment, the cross-sectional width of the rod 1 is 21.31mm-21.33mm, and the cross-sectional height of the rod 1 is 6.80mm-6.82mm; in this way, the side wall and bottom wall of the rod 1 can be matched with the side plate and bottom plate of the back plate respectively, so as to avoid light leakage.

[0027] Working principle: The rod 1 of the aluminum alloy heat dissipation structure is made of 6303 aluminum alloy, which has good strength and corrosion resistance, enabling it to provide stable support and heat dissipation when used in the light-emitting module. The rod 1 is integrally formed by the main body 2, U-shaped groove 3, L-shaped groove 4 and heat dissipation cavity 5. The heat dissipation cavity 5 not only reduces weight and manufacturing cost, but also includes a first through hole 501 and a second through hole 502. The smaller second through hole 502 is located on the left and right sides of the rod 1, which does not affect the mechanical strength of the side of the rod 1, and can better transfer the heat generated by the light-emitting module quickly, thereby improving the life of the light-emitting module.

[0028] All technical features in this embodiment can be freely combined according to actual needs.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
