[0022] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in

[0023] a LED display screen with a double-layer heat dissipation structure of the present utility model includes a LED display screen body 1 and a heat conduction plate 2. A slot 11 is provided on the LED display screen body 1. Both ends and the lower end of the slot 11 are open. The heat conduction plate 2 is arranged in a "U" shape. One end of the heat conduction plate 2 is inserted into the slot 11, and the other end is arranged outside. A plurality of fixing blocks are installed on the back surface of the LED display screen body 1. Connection grooves are provided on the fixing blocks 7. Connection plates 8 are installed on the inner side surfaces of the heat conduction plate 2 corresponding to the connection grooves. The connection plates 8 are inserted into the connection grooves. Air guide openings 9 are provided at the lower ends of the connection plates 8. A plurality of heat dissipation fins 4 are installed on the outer side surface of the heat conduction plate 2;

[0023] After the heat conduction plate is inserted into the slot, the slot can be completely blocked, preventing external dust from entering the interior of the LED display screen body along the slot.

[0024] In this embodiment, limiting plates 3 are installed at both ends in the width direction of the heat conduction plate 2. The distance between the limiting plates 3 matches the width of the LED display screen body 1. The inner side surfaces of the limiting plates 3 are in contact with the outer wall surface of the LED display screen body 1.

[0025] In this embodiment, the cross-sections of the connection plates 8 and the connection grooves are both arranged in a "T" shape. A plurality of ventilation openings are provided on the bottom surface of the heat conduction plate 2. The heat conduction plate can be horizontally connected together through the "T" - shaped connection grooves and connection plates, preventing the heat conduction plate from bending outwards.

[0026] In this embodiment, the heat dissipation fins 4 at the uppermost and lowermost positions are both bent outward to form fixing parts 5, and a plurality of straight notches 6 are provided on each fixing part 5. After the bolts pass through the straight notches, the fixing parts can be fixed on any vertical plane to complete the fixation of the heat conducting plate.

[0027] In this embodiment, a plurality of reinforcing rods 10 are installed inside the LED display body 1. The reinforcing rods 10 are all arranged in an "L" shape. The vertical ends of the reinforcing rods 10 are all arranged inside the outer wall of the back of the LED display body 1, and the horizontal ends of the reinforcing rods 10 are all arranged inside the outer wall of the top of the LED display body 1. The reinforcing rods are made of metal materials, and the firmness of the outer shell of the LED display body can be increased through the reinforcing rods, avoiding cracking of the outer shell due to slots.

[0028] In this embodiment, the heat conducting plate 2 is made of aluminum-magnesium alloy. The comprehensive performance of the aluminum-magnesium alloy is between that of copper and aluminum, with excellent heat conduction performance and relatively high strength. At the same time, it is more affordable compared to copper and is suitable for high-performance heat dissipation.

[0029] During use, the LED display body is directly sleeved on the heat conducting plate through the slot, and is limited left and right by the limiting plate to ensure the stability after the LED display body is inserted.

[0030] The heat conducting plate with the same width as the LED display body can pour out the heat inside and on the outer shell of the LED display body over a large area to complete double-layer internal and external heat dissipation. There is a gap between the end of the heat conducting plate located outside and the LED display body, so that the outside air can pass longitudinally through this gap. During the passing process, it can flow along the air vents, avoiding being blocked. And the outside air can also pass vertically along this gap. During the passing process, it flows along the ventilation ports to ensure the interaction effect between the heat conducting plate and the outside air.

[0031] Moreover, when the LED display body is inserted, the fixing block on the back of the LED display body can be sleeved on the connecting plate through the connecting groove, so that the heat conducting plate can be connected to the LED display body, avoiding the outward bending of the heat conducting plate. At the same time, heat dissipation fins are installed on the back surface of the heat conducting plate to further increase the contact area with the outside air, thereby further improving the heat dissipation effect.

[0032] Among them, the heat conducting plate acts as a bracket during heat dissipation to facilitate the installation of the LED display body. And the LED display body is sleeved on the heat conducting plate and can be disassembled after being lifted upward, greatly facilitating disassembly and assembly.

[0033] The above are only specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be thought of without creative efforts should be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the protection scope defined by the claims.
