Technical Field
[0001] This utility model relates to the field of LED large screen technology, specifically a full-color LED large screen display device. Background Technology
[0002] In today's era of rapid digital information dissemination, the intuitiveness and efficiency of information display are becoming increasingly important. Full-color LED large screen display devices, with their superior characteristics, occupy a key position in many fields. From giant advertising screens on bustling city streets to ultra-large displays in sports stadiums that present exciting moments of the game in real time, and to large background screens that create a dazzling stage effect in various performances, full-color LED large screens have become the core carrier of information dissemination and visual presentation. When a full-color LED large screen is working, the internal LED chips generate a lot of heat. Failure to dissipate heat in time will affect the lifespan of the large screen.
[0003] To address the aforementioned deficiencies, existing technology (Chinese Patent No. CN213635197U, Announcement 2021-07-06) provides a full-color LED large-screen display device. A fan is installed inside a cube-shaped structure composed of a base, a cover, and four full-color LED screen modules, with the fan's airflow direction upwards. This effectively improves the ventilation effect and efficiency inside the cube-shaped structure. A conical guide body is provided at the bottom center of the cover; the upward-flowing air is guided by the guide body and can better flow to the air outlet on the side wall of the cover.
[0004] The above solution uses fans and fluid guides to dissipate heat from the large screen during use. However, when the air flows inside the large screen, the direction and range of the flow are relatively fixed. Therefore, it is not easy to quickly dissipate heat at high temperatures, which will still damage the large screen and affect its subsequent use. Utility Model Content
[0005] The purpose of this utility model is to provide a full-color LED large screen display device to solve the problem mentioned in the background art. Existing full-color LED large screen display devices use fans and fluid guides to dissipate heat from the large screen. However, when the air flows inside the large screen, the flow direction and flow range are relatively fixed. Therefore, it is not easy to quickly dissipate heat at high temperatures, which will still damage the large screen and affect its subsequent use.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a full-color LED large screen display device, including an outer frame, a display screen installed on the front side of the outer frame, a display element installed in the middle of the inner side of the outer frame, a through space symmetrically arranged at the bottom of the outer frame, a mesh at the bottom of the through space of the outer frame, a motor arranged above the mesh, a fan connected to the output end of the motor, and the fan located at the bottom inner side of the outer frame.
[0007] The outer frame is symmetrically provided with air supply pipes, and air outlets for outputting air are opened at equal intervals on the left and right sides of the air supply pipes.
[0008] Heat-absorbing blocks are evenly spaced and run through the left and right sides of the outer frame, and a through hole for air circulation is provided in the middle of the heat-absorbing block.
[0009] The back of the outer frame is provided with heat dissipation fins at equal intervals to assist in heat dissipation.
[0010] Furthermore, the fan outlet is provided with an air concentrator, which is symmetrically installed on the bottom inner side of the outer frame and is configured as a cylindrical structure.
[0011] Furthermore, the top of the air-gathering duct is connected to the bottom of the air-supplying pipe, and air guide ducts are provided on both the left and right sides of the air-supplying pipe. The air guide ducts are configured with a trumpet-shaped structure, and the air holes are located in the middle of the air guide ducts.
[0012] Furthermore, the outer frame forms a lateral air outlet heat dissipation structure through heat-absorbing blocks and through holes, and air guides are provided in the through holes, with the air guides having a spiral structure.
[0013] Furthermore, the air guide plate is a thin sheet, which increases the contact area and time between the heat absorption block and the heat.
[0014] Furthermore, a horizontal ventilation channel is provided through the middle of the side of the heat dissipation fins, and a vertical ventilation channel is provided through the vertical direction of the heat dissipation fins at equal intervals.
[0015] Furthermore, the horizontal and vertical ventilation ducts are interconnected, and the heat dissipation fins increase the airflow space through the horizontal and vertical ventilation ducts.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This full-color LED large screen display device can evenly deliver air into the internal space of the large screen during use, and the heat is carried out to the outside through even air blowing. At the same time, the heat absorption and drainage on the side and the heat absorption and heat dissipation components on the back can accelerate the dissipation of heat, thereby improving heat dissipation efficiency, extending the service life of the large screen, and avoiding heat damage.
[0018] 1. Furthermore, when the display components and screen inside the outer frame generate heat, the motor is started. After the motor starts, it will drive the fan to run. The air generated by the fan will be blown evenly inside the outer frame through the air duct. After the air flows, the heat is output from the through holes in the heat absorption blocks on both sides. At the same time, the heat dissipation fins on the rear side of the outer frame will also dissipate heat simultaneously, thereby quickly dissipating the heat and preventing the large screen from overheating and being damaged.
[0019] 2. Furthermore, the air generated by the fan's movement will be concentrated in the air-collecting duct, which will then deliver the air to the air-dissipating duct. The air-dissipating duct will blow the air out evenly through the air holes, and the air guide tube on the outside of the air-dissipating duct can diffuse the air and expand the range of even heat dissipation.
[0020] 3. Furthermore, when hot air is blown out from the through holes in the heat-absorbing block, the heat-absorbing block can absorb the heat, and the airflow also accelerates the dissipation of heat from the heat-absorbing block itself, thereby improving the overall heat dissipation efficiency of the large screen. The spiral-rotating air guide vanes increase the contact area between the air and the heat-absorbing block, and the rotating output air can accelerate the airflow speed.
[0021] 4. Furthermore, when the heat dissipation fins conduct heat and dissipate heat, the horizontal and vertical ventilation channels can expand the airflow space. This allows the airflow to carry away the heat from the heat dissipation fins when there is external wind, thereby improving the overall heat dissipation efficiency and quality of the large screen.

[0031] During use, when the display components 3 and the display screen 2 inside the outer frame 1 generate heat, the motor 4 is started. After the motor 4 starts, it will drive the fan 5 to run. The air generated by the fan 5 will be blown evenly inside the outer frame 1 through the air duct 8. After the air flows, the heat is output from the through holes 12 in the heat absorption blocks 11 on both sides. At the same time, the heat dissipation fins 14 on the rear side of the outer frame 1 will also perform heat dissipation treatment simultaneously, thereby quickly dissipating the heat and preventing the large screen from overheating and being damaged.
[0032] Example 2:
[0033] Based on Embodiment 1, the air-concentrating duct 7 and the air-guiding duct 10 are also disclosed. Please refer to [reference needed]. Figures 3-4 As shown, its specific structure is as follows: A concentrator 7 is provided at the air outlet of the fan 5. The concentrator 7 is symmetrically installed on the bottom inner side of the outer frame 1. The concentrator 7 is set as a cylindrical structure. The top of the concentrator 7 is connected to the bottom of the air supply pipe 8. Air guides 10 are provided on the left and right sides of the air supply pipe 8. The air guides 10 are set as trumpet-shaped structures. The air hole 9 is located in the middle of the air guide 10.
[0034] When in use, the air generated by the fan 5 will be concentrated in the air-collecting tube 7, and the air-collecting tube 7 will then deliver the air to the air-dissipating tube 8. The air-dissipating tube 8 will blow the air out evenly through the air holes 9. The air guide tube 10 on the outside of the air-dissipating tube 8 can diffuse the air and expand the range of even heat dissipation and air blowing.
[0035] Example 3:
[0036] Based on Embodiment 2, a guide vane 13 is also disclosed; please refer to [reference needed]. Figures 1-3 and Figure 5 As shown, its specific structure is as follows: the outer frame 1 forms a side air outlet heat dissipation structure by means of heat absorption block 11 and through hole 12. A guide plate 13 is provided in the through hole 12. The guide plate 13 is set in a spiral structure and is a thin plate. The guide plate 13 increases the contact area and time between the heat absorption block 11 and the heat.
[0037] When in use, when hot air is blown out from the through hole 12 in the heat absorption block 11, the heat absorption block 11 can absorb the heat, and the airflow also accelerates the dissipation of heat from the heat absorption block 11 itself, thereby improving the overall heat dissipation efficiency of the large screen. The spiral air guide 13 increases the contact area between the air and the heat absorption block 11, and the rotating output air can accelerate the airflow.
[0038] Example 4:
[0039] Based on Embodiment 3, a horizontal ventilation duct 15 and a vertical ventilation duct 16 are also disclosed. Please refer to [reference needed]. Figure 2 and Figure 6 As shown, its specific structure is as follows: a horizontal ventilation channel 15 is provided through the middle of the side of the heat dissipation fin 14, and a vertical ventilation channel 16 is provided through the vertical direction of the heat dissipation fin 14 at equal intervals.

[0040] When in use, the heat dissipation fins 14 conduct heat and dissipate heat, while the horizontal ventilation channels 15 and vertical ventilation channels 16 can expand the airflow space. Thus, when there is wind outside, the flowing wind can carry away the heat on the heat dissipation fins 14 as it passes through the horizontal ventilation channels 15 and vertical ventilation channels 16, thereby improving the overall heat dissipation efficiency and quality of the large screen.
