[0002] With the continuous development of technology, LED display screens are widely used in various fields, such as advertising, stage, stadiums, etc. However, during long-term use, LED display screens will generate a large amount of heat. If the heat dissipation is poor, it will lead to problems such as a decline in the performance of the display screen and a shortening of its lifespan.

[0003] However, for the heat dissipation of existing LED display screens, generally, a heat dissipation fan is set at the side end to directly blow air on the circuit board of the LED display screen for heat dissipation. However, in this way, the circuit board may be damaged by the blowing for a long time, affecting its working stability.

[0004] To solve this technical problem, the utility model proposes an LED display screen with an integrated heat dissipation structure. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an LED display screen with an integrated heat dissipation structure, which can effectively solve the problems mentioned in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0011] Preferably, mounting holes are provided in both the heat-conducting layer and the heat-dissipating fins, and the mounting holes of the two correspond and communicate with each other. They can be connected by a bolt rod, and the depth of the mounting hole is longer than the length of the bolt rod. A gasket is provided between the bolt rod and the heat-dissipating fins.

[0012] Preferably, a transparent protective glass is provided at the front end of the outer frame. An anti-laser coating is applied to the inner side of the transparent protective glass.

Specifically, the heat generated by the display screen main board will be conducted to the heat-dissipating fins through the heat-conducting layer, and the heat-dissipating fan will blow air towards the heat-dissipating fins to accelerate air flow and improve the heat dissipation effect. Moreover, the connection between the groove and the rib can expand the contact area between the heat-conducting layer and the heat-dissipating fins, thereby increasing the heat exchange area, which can improve the heat conduction and thus improve the heat dissipation effect of the device.

A rib 5 is connected to the side end of the heat dissipation fin 4. The heat dissipation fin 4 and the rib 5 are made of the same material, which is copper or aluminum, and has good heat conduction performance, which is beneficial to the heat dissipation of the device. The rib 5 is inserted into the groove 3, so as to expand the contact area between the heat conduction layer 2 and the heat dissipation fin 4, thereby increasing the heat exchange area, and thus improving the heat conduction.

[0027] Both the heat-conducting layer 2 and the heat-dissipating fins 4 are provided with mounting holes 11, and the mounting holes 11 of the two correspond and communicate with each other. They can be connected by a bolt rod 12. The bolt rod 12 passes through the mounting holes 11 to connect the heat-dissipating fins 4 and the heat-conducting layer 2 together, so that the display main board 1, the heat-conducting layer 2, and the heat-dissipating fins 4 are connected as a whole to improve the heat dissipation efficiency of the display main board 1. The depth of the mounting hole 11 is longer than the length of the bolt rod 12. By rotating the bolt rod 12 forcefully, the heat-dissipating fins 4 can be squeezed, so that the convex strips 5 and the grooves 3 are closely attached.

It can well absorb and block infrared and ultraviolet rays while maintaining high transparency (prior art), so as to effectively isolate the transmission of external heat to the display main board 1. The transparent protective glass 13 is located at the front end of the display main board 1. A sealing ring is provided at the connection gap between the transparent protective glass 13 and the outer frame 6.

An air outlet 10 is provided at the lower end of the outer frame 6. A filter tube 14 is connected to the upper end of the heat dissipation fan 9. Two filter plates 15 are clamped in the filter tube 14. The two filter plates 15 are arranged up and down. A filter plate 15 is provided in the air outlet 10. The filter plate 15 is used to prevent dust from entering the device. The air inlet 7 is located directly above the heat-dissipating fins 4, and the air outlet 10 is located directly below the heat-dissipating fins 4.
