Description

Technical Field

[0001] The utility model relates to the technical field of heat dissipation of LED display screens, in particular to a heat dissipation structure of an LED display screen. Background Technique

[0002] An LED display screen is a screen that uses a light-emitting diode display method. It is usually composed of multiple light-emitting diodes. By controlling the lighting and extinguishing of the light-emitting diodes, it can display characters, images, animations, videos and other information. Since the LED display screen generates heat when working for a long time, it is necessary to dissipate heat at this time to ensure the normal operation of the display screen.

[0003] An LED display screen heat dissipation structure with the publication number of CN220733270U takes a cross frame and a longitudinal frame as the main body. The cross frame and the longitudinal frame form a splicing frame body. An LED display module is fixed on the splicing frame body. A protective cover is arranged on the back side of the splicing frame body, and the protective cover is buckled on the rear side of the LED display screen. An air outlet pipe is fixed on the protective cover. Air outlet holes are opened on the air outlet pipe, and the air outlet holes face the LED display module. An air outlet opening is opened on the protective cover. A cold air blower is fixedly installed outside the protective cover. The air inlet end of the cold air blower is connected to the air outlet pipe. A dust filter cylinder is installed on the protective cover. Cold air is output by the cold air blower and blown to the LED display module through the air outlet holes at the air outlet pipe, so as to dissipate heat from it and ensure the normal display of the LED display module.

[0004] There are still problems in the above-mentioned LED display screen heat dissipation structure. Most of the LED display screens used are thin and light displays. This display screen heat dissipation structure consists of a protective cover, an air outlet pipe, a cold air blower and other structures. The structure is complex and the volume is large. Heat dissipation is carried out through air flow, and the heat dissipation efficiency is low. Therefore, a heat dissipation structure of an LED display screen is proposed. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art, the heat dissipation devices on the market have complex structures and large volumes, and the heat dissipation efficiency is low by air flow. The utility model proposes a heat dissipation structure of an LED display screen.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: A heat dissipation structure of an LED display screen described in the utility model includes a display screen body; a heat dissipation mechanism is arranged on the side of the display screen body, a protection mechanism is buckled on the side of the display screen body, a fixing mechanism is arranged at the north edge position of the display screen body, and heat conduction pads are uniformly fixed on the side of the display screen body.

[0007] Preferably, the heat dissipation mechanism includes a heat conduction pad. A copper tube is closely attached to the side of the heat conduction pad. A first hollow tube is fixed to the top of the copper tube, and a second hollow tube is fixed to the bottom of the copper tube. Heat dissipation plates are symmetrically fixed to both ends of the first hollow tube and the second hollow tube. Heat dissipation fins are fixed to the side of the heat dissipation plates. A cavity is formed inside the heat dissipation plates. The first hollow tube, the second hollow tube and the cavity are internally communicated. The copper tube is flat-shaped. A housing is buckled on the side of the display screen body. Through the cooperation of the copper tube and the heat dissipation plates, the heat generated by the display screen is transferred to the external environment. While dissipating heat, this structure is smaller in volume and lighter, and can be applied to various display environments.

[0008] Preferably, the protection mechanism includes a housing. Limiting grooves are formed at the four corners inside the housing. The limiting grooves are buckled on both ends of the first hollow tube and the second hollow tube. A rubber pad is fixed to the inner surface of the housing, and the rubber pad closely adheres to the surface of the copper tube. Fixing rods are symmetrically fixed to both ends of the side of the housing. Gratings are evenly fixed to the circumferential surface of the fixing rods. The gratings are buckled on one side of the heat dissipation plates. A frame is fixedly sleeved on the display screen body. Through the structure of the gratings, the structure is simple and can prevent the heat dissipation fins from being knocked, thereby preventing the deformation and damage of the heat dissipation structure.

[0009] Preferably, the fixing mechanism includes a frame. Fixing seats are fixed to the four corners of the side of the frame. Screws are rotatably inserted into the fixing seats through threaded cooperation. Fixing holes are symmetrically formed at both ends of the side of the housing. One end of the screw passes through the fixing seat and is inserted into the fixing hole. Through the cooperation of the screws for fixation, the structure is simple and convenient for disassembly and assembly, facilitating subsequent maintenance.

[0010] The beneficial effects of the present utility model are as follows:

[0011] 1. Through the structural design of a heat dissipation structure for an LED display screen of the present utility model, by setting the heat dissipation mechanism, during the use of the display screen body, the heat generated by it is transferred to the coolant inside the copper tube through the heat conduction pad, causing it to heat up. At this time, the heated coolant flows upward into the first hollow tube, and then is transported into the cavity inside the heat dissipation plate. The heat absorbed by the coolant is dissipated into the air through the heat dissipation fins. At this time, the cooled coolant flows downward inside the cavity, flows back into the copper tube through the second hollow tube, thereby realizing the function of the coolant circulating flow. This structure is small in volume and can directly transfer the heat generated by the display screen body to the external environment, with higher heat dissipation efficiency, solving the problems of the existing heat dissipation structure being large in volume and low in heat dissipation efficiency.

[0012] 2. Through the structural design of a heat dissipation structure for an LED display screen, by setting up a protection mechanism, the housing is buckled on one side of the copper tube, placing it in a sealed environment to prevent it from being knocked, and at the same time, the rubber pad makes the copper tube closely adhere to the surface of the heat conduction pad, ensuring that the heat dissipation efficiency will not decrease and dust will not accumulate on the surface of the copper tube. At this time, the grille is buckled on one side of the heat dissipation fins, which can protect it while not affecting its heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0022] Please refer to Figure 2 As shown in the figure, the heat dissipation mechanism includes a heat conduction pad 3. A copper tube 4 is closely attached to the side of the heat conduction pad 3. A first hollow tube 5 is fixed to the top end of the copper tube 4, and a second hollow tube 6 is fixed to the bottom end of the copper tube 4. Heat dissipation plates 7 are symmetrically fixed to both ends of the first hollow tube 5 and the second hollow tube 6. Heat dissipation fins 9 are fixed to the side of the heat dissipation plate 7. A cavity 8 is formed inside the heat dissipation plate 7. The first hollow tube 5 and the second hollow tube 6 are communicated with the inside of the cavity 8. The copper tube 4 is in a flat shape. A housing 10 is buckled on the side of the display screen body 1; during operation, when encountering the problems of large volume and low heat dissipation efficiency of the existing heat dissipation structure, through the structure of the heat dissipation mechanism, during the use of the display screen body 1, the heat generated by it is transferred to the coolant inside the copper tube 4 through the heat conduction pad 3, causing it to heat up. At this time, the heated coolant flows upward into the first hollow tube 5 and then is transported into the cavity 8 inside the heat dissipation plate 7. The heat absorbed by the coolant is dissipated into the air through the heat dissipation fins 9. At this time, the cooled coolant flows downward inside the cavity 8 and flows back into the copper tube 4 through the second hollow tube 6, thus realizing the function of circulating flow of the coolant. This structure is small in volume and can directly transfer the heat generated by the display screen body 1 to the external environment, with higher heat dissipation efficiency.

[0023] Please refer to Figure 3 As shown in the figure, the protection mechanism includes a housing 10. Limit grooves 11 are formed at the four corners inside the housing 10. The limit grooves 11 are buckled on both ends of the first hollow tube 5 and the second hollow tube 6. A rubber pad 12 is fixed to the inner surface of the housing 10, and the rubber pad 12 closely adheres to the surface of the copper tube 4. Fixing rods 13 are symmetrically fixed to both ends of the side of the housing 10. Gratings 14 are evenly fixed on the circumferential surface of the fixing rods 13. The gratings 14 are buckled on one side of the heat dissipation plate 7. A frame 2 is fixedly sleeved on the display screen body 1; during operation, when encountering the problem that the heat dissipation structure is easily damaged and leaks liquid when bumped, through the structure of the protection mechanism, the housing 10 is buckled on one side of the copper tube 4 to make it in a sealed environment to prevent it from being bumped. At the same time, the rubber pad 12 makes the copper tube 4 closely adhere to the surface of the heat conduction pad 3, ensuring that the heat dissipation efficiency will not decrease and dust will not accumulate on the surface of the copper tube 4. At this time, the gratings 14 are buckled on one side of the heat dissipation fins 9, which can protect them while not affecting their heat dissipation efficiency.

[0024] Please refer to Figure 4As shown, the fixing mechanism includes a frame 2, and fixing seats 15 are fixedly arranged at the four corners on the side of the frame 2. A screw 17 is rotatably inserted into the inner side of the fixing seat 15 through threaded fit. Fixing holes 16 are symmetrically formed at both ends on the side of the housing 10, and one end of the screw 17 passes through the fixing seat 15 and is inserted and installed inside the fixing hole 16. During operation, when encountering the problem that the existing heat dissipation mechanism is inconvenient to disassemble and assemble and the maintenance efficiency is low, through the structure of the fixing mechanism, the screw 17 is rotated to be pulled out from the inner side of the fixing seat 15. At this time, the housing 10 can be removed, so as to maintain the heat dissipation structure inside it. After the maintenance is completed, the housing 10 is buckled inside the fixing seat 15, and the screw 17 is passed through the fixing seat 15 and inserted into the fixing hole 16 again, so that the housing 10 can be fixed in place. The disassembly and assembly are rapid, and it is more convenient to use.

[0025] Please refer to Figure 5 As shown, metal sheets 18 are uniformly fixed on the back side of the housing 10. During operation, when encountering the problem that the display screen generates a large amount of heat, through the structure of the metal sheets 18, the contact area between the housing 10 and the air is increased, so as to transfer the heat inside the housing 10 to the outside, playing a role in assisting heat dissipation and improving the heat dissipation efficiency.

[0026] Working principle: An LED display screen is a screen that uses a light-emitting diode display method. It is usually composed of multiple light-emitting diodes. By controlling the lighting and extinguishing of the light-emitting diodes, it can display information such as characters, images, animations, and videos. Since heat is generated when the LED display screen works for a long time, it is necessary to dissipate the heat at this time to ensure the normal operation of the display screen. When the existing heat dissipation structure is used, since most of the LED display screens are thin and light monitors, the heat dissipation structure of the display screen consists of a protective cover, an air outlet pipe, a cooling fan, and other structures. The structure is complex and the volume is large. Heat is dissipated through air flow, and the heat dissipation efficiency is low. To solve this problem, by setting up a heat dissipation mechanism and a protection mechanism, the housing 10 is placed inside the fixing seat 15, and the screw 17 passes through the fixing seat 15 and is inserted into the fixing hole 16 again to fix the position of the housing 10. At this time, the housing 10 is buckled on one side of the copper pipe 4, making the copper pipe 4 in a sealed environment to prevent it from being knocked. At the same time, the rubber pad 12 makes the copper pipe 4 closely attached to the surface of the heat conduction pad 3, ensuring that the heat dissipation efficiency will not decrease and dust will not accumulate on the surface of the copper pipe 4. At this time, the grille 14 is buckled on one side of the heat dissipation fins 9, which can protect it while not affecting its heat dissipation efficiency. When the display screen body 1 is in use, the heat generated by it is transferred to the coolant inside the copper pipe 4 through the heat conduction pad 3, causing it to heat up. At this time, the heated coolant flows upward into the first hollow pipe 5 and then is transported into the cavity 8 inside the heat dissipation plate 7. The heat absorbed by the coolant is dissipated into the air through the heat dissipation fins 9. At this time, the cooled coolant flows downward inside the cavity 8 and flows back into the copper pipe 4 through the second hollow pipe 6, thus realizing the function of the coolant circulating flow, enabling the heat generated by the display screen body 1 to be directly transferred to the external environment. This structure is small in volume and has a higher heat dissipation efficiency. When maintenance is required, turn the screw 17 and pull it out from the inside of the fixing seat 15. At this time, the housing 10 can be removed, and then the heat dissipation structure inside it can be maintained. After the maintenance is completed, fix the housing 10 back to its original position in the same way, and then it can be used, solving the problems of the existing heat dissipation structure with a large volume and low heat dissipation efficiency.
