Description

Technical Field

[0001] This utility model relates to the technical field of die-cast aluminum enclosures for LED displays, and specifically to a die-cast aluminum enclosure for LED displays with heat dissipation fins. Background Technology

[0002] Die-cast aluminum enclosures are an important component of LED displays, playing a crucial role in ensuring stable operation, optimizing display effects, and facilitating installation and maintenance. For example, patent document CN220528447U discloses a die-cast aluminum enclosure for LED displays. This enclosure utilizes the coordinated use of connecting pipes, a vacuum pump, and an air outlet. When the vacuum pump starts, it transfers the air inside through the connecting pipes, which then circulates back and forth before being discharged through the air outlet. This solves the heat dissipation problem of the enclosure, keeping it cool for extended periods.

[0003] However, the fixed position of the internal air outlet of the aforementioned die-cast aluminum LED display cabinet prevents it from dissipating heat evenly inside the cabinet. Utility Model Content

[0004] In view of the problems existing in the existing die-cast aluminum housings for LED displays with heat dissipation fins, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a die-cast aluminum enclosure for LED displays with heat dissipation fins, which solves the problem that the internal air outlet of the existing die-cast aluminum enclosure for LED displays is fixed in position and cannot dissipate heat evenly inside the enclosure.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

One end of each of the plurality of exhaust pipes located inside the enclosure body is connected to a duct pipe. The bottom of the duct pipe is connected to a heat dissipation pipe.

[0008] A reciprocating screw is rotatably inserted through the bottom of the inner wall of the housing. A sliding plate is threaded onto the rod wall of the reciprocating screw and is fixedly fitted onto the outer wall of the plurality of heat dissipation pipes.

[0009] Preferably, the outer wall of the connecting pipe is connected to a cover, a crossbar is rotatably inserted inside the cover, an impeller is fixedly sleeved on the wall of the crossbar, and the blade end of the impeller extends into the connecting pipe;

[0010] An installation plate is fixedly provided on the outer wall of the cover. A vertical rod is rotatably inserted through the interior of the installation plate. A transmission rod is rotatably inserted through the lower side of the box. A first bevel gear is fixedly provided at both ends of the transmission rod. A second bevel gear is fixedly provided at both ends of the vertical rod. Two adjacent first bevel gears and second bevel gears are engaged.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model discloses a die-cast aluminum housing for an LED display screen with heat dissipation fins.

[0027] This utility model provides, for example Figure 1-4 The image shows a die-cast aluminum enclosure for an LED display screen with heat dissipation fins, comprising an enclosure 1 and an LED display screen 2 located on the front side of the enclosure 1. Multiple heat dissipation fins 3 are fixedly arranged at intervals on the outer wall of the enclosure 1. Each heat dissipation fin 3 has an exhaust pipe 4 passing through its interior. The heat dissipation fin 3 has a through hole 22 that matches the exhaust pipe 4. The upper ends of the multiple exhaust pipes 4 are connected to a horizontal pipe 5. A connecting pipe 6 is connected to the wall of the horizontal pipe 5. An air pump 7 is fixedly fitted at the lower end of the connecting pipe 6. One end of each of the multiple exhaust pipes 4 located inside the enclosure 1 is connected to a duct pipe 8. Each duct pipe 8 is a telescopic corrugated pipe. A heat dissipation pipe 9 is connected to the bottom of the duct pipe 8. The exhaust pipes 4, the horizontal pipes 5, and the connecting pipe 6 are all made of rigid plastic.

[0028] A reciprocating screw 10 is rotatably inserted through the bottom of the inner wall of the housing 1. A sliding plate 11 is threaded onto the wall of the reciprocating screw 10. The sliding plate 11 contacts and engages with the inner side wall of the housing 1. The sliding plate 11 is fixedly sleeved on the outer wall of multiple heat dissipation pipes 9.

[0029] In order to drive the reciprocating screw 10 to rotate and cause multiple heat dissipation pipes 9 to move longitudinally, thereby increasing the flow range of cooling airflow, such as Figure 1-3 As shown, the outer wall of the connecting pipe 6 is connected to a cover 12, and a crossbar 13 is rotatably inserted inside the cover 12. An impeller 14 is fixedly sleeved on the wall of the crossbar 13, and the blade end of the impeller 14 extends into the connecting pipe 6.

[0030] A mounting plate 15 is fixedly installed on the outer wall of the cover 12. A vertical rod 16 is rotatably inserted through the inside of the mounting plate 15. A transmission rod 17 is rotatably inserted through the lower side of the box 1. A first bevel gear 18 is fixedly installed at both ends of the transmission rod 17. A second bevel gear 19 is fixedly installed at both ends of the vertical rod 16. Two adjacent first bevel gears 18 and second bevel gears 19 are fitted together. A third bevel gear 20 and a fourth bevel gear 21 are respectively fixedly fitted on the walls of the reciprocating screw 10 and the crossbar 13. The third bevel gear 20 is fitted with the first bevel gear 18, and the fourth bevel gear 21 is fitted with the second bevel gear 19.

[0031] Working principle: When the LED display screen starts working, the air pump 7 is activated. The air pump 7 draws in and pressurizes outside air through the connecting pipe 6 and the horizontal pipe 5, causing the air to flow along the air outlet pipe 4. Since the air outlet pipe 4 passes through the heat dissipation fins 3, the heat dissipation fins 3 can increase the contact area with the air, accelerate heat dissipation, and initially reduce the air temperature. The cooled air enters the heat dissipation pipe 9 through the air guide pipe 8. The gas drawn by the air pump 7 quickly passes through the connecting pipe 6. The high-speed flowing gas impacts the impeller 14, driving the horizontal bar 13 to rotate. The fourth bevel gear 21 on the wall of the horizontal bar 13 rotates together with the horizontal bar 13. The fourth bevel gear 21 meshes with the second bevel gear 19 at the end of the vertical bar 16, thereby driving the vertical bar 16 to rotate. The second bevel gear 19 at the other end of the vertical bar 16 then engages with the first bevel gear 18 at the end of the transmission rod 17, causing the transmission rod 17 to rotate. The first bevel gear 18 at the other end of the transmission rod 17 meshes with the third bevel gear 20 on the reciprocating screw 10, ultimately driving the reciprocating screw 10 to rotate.

[0032] When the reciprocating screw 10 rotates, the sliding plate 11, which is threaded to it, will move longitudinally on the inner wall of the housing 1. Since the sliding plate 11 is fixedly sleeved on the outer wall of multiple heat dissipation pipes 9, the heat dissipation pipes 9 will move up and down together with the sliding plate 11. The air guide pipe 8 is a telescopic corrugated pipe, which can adapt to the movement of the heat dissipation pipes 9 and ensure stable gas delivery. During the movement of the heat dissipation pipes 9, the cooling airflow blown out from the heat dissipation pipes 9 can dissipate heat at different height positions inside the housing 1, thereby improving the uniformity of cooling and ensuring that the LED display screen works in a stable temperature environment.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
