[0002] In an era with extremely strong demands for information dissemination and visual display, LED full-color display modules, with their many advantages such as high brightness, rich colors, wide viewing angles, and fast response speeds, are widely used in many fields such as advertising, stage performances, traffic information display, monitoring and command centers, and education. However, with the continuous development of LED full-color display technology, its power density continues to increase, and the heat dissipation problem has gradually become a key factor restricting the improvement of its performance and the expansion of its applications.

[0003] However, there are some problems in the actual working process of existing LED full-color display modules. For example, a new single-lamp dual-pixel type 3D LED display module with the publication number CN118763085B, although it uses a heat dissipation structure to achieve air cooling of the LED full-color display module and can change the heat dissipation amount through a driving heat dissipation fin adjustment mechanism, in the actual working process, it only relies on the cooperation of heat dissipation fins and a heat dissipation fan for heat dissipation, and the heat dissipation efficiency is low, making it difficult to meet the heat dissipation requirements of high-power LED full-color display modules. Therefore, in hot seasons or in working environments where the LED full-color display module needs to work for a long time under high load, the heat dissipation intensity of the heat dissipation mechanism cannot be adjusted in multiple levels according to actual needs, and thus the LED full-color display module cannot be guaranteed to be cooled efficiently and dissipated, so that it is in a reasonable temperature range, and thus the stable and safe long-term working state of the LED full-color display module cannot be guaranteed, and the practicability is poor. Therefore, we make improvements on this and propose a heat dissipation structure for an LED full-color display module. Summary of the Invention

[0015] Beneficial effects The beneficial effects of a heat dissipation structure for an LED full-color display module provided by the present invention are as follows: 1. Driven by the first motor provided, the mounting plate on the reciprocating lead screw can drive the first heat insulation box and the second heat insulation box to perform automatic and stable up-and-down reciprocating motion. At this time, under the combined action of the traction rope and the coil, the spiral rods on both sides can be driven to perform automatic and stable reciprocating rotation in the corresponding conveying cylinders, and then the cooled water in the first heat insulation box and the second heat insulation box can be driven to circulate in the first diversion pipe, the second diversion pipe, the first connecting pipe, and the second connecting pipe. Using the principle of heat exchange, rapid cooling of the surrounding air is achieved. At the same time, combined with the rotation of the exhaust fans on both sides, the cooled air can be pushed to the circuit board inside the first protective housing to achieve primary cooling and heat dissipation of the LED full-color display module.

[0016] 2. Driven by the threads of the sleeve rod and the threaded rod provided, the second connecting pipe can be pushed to move on the connecting ring and fit with the push block. At this time, during the rotation and heat dissipation process of the exhaust fan, the connecting ring can be driven to rotate synchronously through the connecting rod on the telescopic rod. Therefore, the cooling water circulating in the second connecting pipe can be automatically and evenly transported into the sponge plates on each connecting rod through the first through groove and the second through groove. At this time, the surrounding air not only exchanges heat with the first diversion pipe, the second diversion pipe, the first connecting pipe, and the second connecting pipe, but also can absorb heat through the evaporation of the cooling water inside the sponge plate to further cool and refrigerate the surrounding air, and then can further enhance the cooling and heat dissipation effect on the LED full-color display module.

[0017] 3. By continuously rotating the set threaded rod, the connecting ring on the push block can be driven to move synchronously through the second connecting pipe, and the sponge plate can be driven to fit with the first heat conducting rod. At this time, under the rotation of each sponge plate and the overall up-and-down reciprocating movement of the multi-stage heat dissipation assembly, the cooling water can be evenly applied to each first heat conducting rod. At this time, with the combined action of the heat exchange between the first diversion pipe, the second diversion pipe, the first connecting pipe, the second connecting pipe and the air, the evaporation heat absorption of the cooling water inside the sponge plate and the evaporation heat absorption of the cooling water on each first heat conducting rod, the cooling efficiency and effect of the LED full-color display module are further improved. To sum up, according to the actual working environment and working intensity of the LED full-color display module, the multi-stage adjustment of the cooling intensity of the cooling structure can be realized, which can more flexibly cope with different working conditions, avoid overheating or overcooling, control the temperature of the LED full-color display module within a reasonable range, effectively slow down the aging speed of electronic components, extend the service life of the display module, reduce the maintenance cost and replacement frequency, and reduce energy consumption while improving the heat dissipation efficiency.

[0018] 4. Through the set ventilation cylinder and exhaust pipe, the stable circulation of the air inside the LED full-color display module is realized, ensuring the stability of the subsequent heat dissipation work. And through the filter plate, the dust and impurities in the air can be stably filtered. And while the mounting plate moves up and down reciprocally, the scraping rod on the connecting shaft can be driven to rotate automatically through the third gear and the rack, and then the impurities and dust filtered on the filter plate can be automatically cleaned, ensuring the stability of the filter plate during long-term operation. And the cleaned dust and impurities can be automatically collected into the ventilation cylinder for subsequent transfer and treatment to avoid environmental pollution.

[0019] 5. Through the cooperation of the set clamping rod and clamping groove, the convenient disassembly and assembly of the ventilation cylinder are realized, which can ensure the convenience of the subsequent cleaning work of the ventilation cylinder and the filter plate. And through the disassembly and assembly of the ventilation cylinder, the convenience of the adjustment work of the multi-stage heat dissipation assembly can be ensured, increasing the diversity and convenience of the use of the heat dissipation structure.

[0030] Embodiment 3: The solutions in Embodiment 1 and Embodiment 2 are further introduced below in combination with specific working modes, as detailed in the following description: Specifically, when the heat dissipation structure of this LED full-color display module is in use: First, when the LED full-color display module starts to work, driven by the first motor 3, it can drive the reciprocating lead screw 4 to rotate stably, and then drive the threaded mounting plate 5 to move up and down reciprocally. At this time, the mounting plate 5 can drive the first heat insulation box 601 and the second heat insulation box 603 to move synchronously. When the first heat insulation box 601 and the second heat insulation box 603 move downward, under the pulling action of the traction rope 609, they can drive the spiral rod 607 to rotate automatically in the positive direction through the coil 608. When the first heat insulation box 601 and the second heat insulation box 603 move upward, under the elastic action of the scroll spring 611 inside the limit frame 610, they can drive the spiral rod 607 and the coil 608 to rotate automatically in the reverse direction and automatically wind up the traction rope 609. Repeating this process, it can drive the spiral rod 607 to rotate stably in the positive and reverse directions in the conveying cylinder 606. When the spiral rod 607 rotates in the positive direction, the water in the first heat insulation box 601 can be transported through the conveying cylinder 606 and the first hose 612 into the first diversion pipe 613. Subsequently, the water sequentially passes through the first diversion pipe 613, the second diversion pipe 614, the second connecting pipe 620, the first connecting pipe 619, the second diversion pipe 614, and the second hose 615, and is stably transported into the second heat insulation box 603. Subsequently, when the spiral rod 607 rotates in the reverse direction, the water flow reverses, realizing the reciprocating flow of water. And during its reciprocating flow process, under the action of the refrigeration sheet 605, the water can be continuously and evenly cooled. Moreover, the heat dissipation end of the refrigeration sheet 605 can discharge the heat out of the second protective shell 2 through contact with the heat conduction plate 8, realizing stable heat dissipation, and thus the water can be continuously and stably cooled; Meanwhile, during the up and down reciprocating movement of the first heat insulation box 601 and the second heat insulation box 603, driven by the second motor 624, the first gear 625 on the output shaft can drive the second gears 626 on both sides to mesh and rotate, and then drive the exhaust fans 628 on the drive shafts 627 on both sides to rotate simultaneously. At this time, under the continuous rotation of the exhaust fans 628, external air enters through the ventilation cylinder 702, and then after contacting the first diversion pipe 613, the second diversion pipe 614, the first connecting pipe 619, and the second connecting pipe 620, it can be transported into the first protective shell 1 through the moisture removal mesh plate 10. At this time, the excess air inside the first protective shell 1 is discharged through the exhaust pipe 17, realizing air circulation; During the process of the water cooled inside the first heat insulation box 601 and the second heat insulation box 603 circulating in the first diversion pipe 613, the second diversion pipe 614, the first connecting pipe 619 and the second connecting pipe 620, by using the principle of heat exchange, the surrounding air is quickly cooled. At the same time, combined with the rotation of the exhaust fans 628 on both sides, the cooled air can be pushed to the circuit board 14 inside the first protective housing 1, realizing the primary cooling and heat dissipation of the LED full-color display module; When the weather is relatively hot, or when the LED full-color display module needs to work under high load for a long time, before installing the LED full-color display module, the staff can rotate the threaded rod 617 on the fixing plate 618 in advance. Under the rotation of the threaded rod 617, the sleeve rod 616 connected by threads can be used to push the first diversion pipe 613 and the second diversion pipe 614 towards the dehumidification mesh plate 10. Under the movement of the first diversion pipe 613 and the second diversion pipe 614, the second connecting pipe 620 can be driven to move synchronously through the first connecting pipe 619 and fit with the push block 634 on the connecting ring 632; Subsequently, during the subsequent operation of the LED full-color display module, when the exhaust fan 628 rotates, it can drive each connecting rod 630 to rotate synchronously through the telescopic rod 629, and can drive the sponge plate 631 and the connecting ring 632 to rotate synchronously through the connecting rod 630. At this time, under the rotation of the connecting ring 632, the second through groove 633 can be driven to intermittently align with the first through groove 622 on the second connecting pipe 620. At this time, the cooling water circulating inside the second connecting pipe 620 can be automatically and evenly delivered into the sponge plate 631 on each connecting rod 630 through the intermittently aligned first through groove 622 and the second through groove 633. At this time, the surrounding air not only exchanges heat with the first diversion pipe 613, the second diversion pipe 614, the first connecting pipe 619 and the second connecting pipe 620, but also can further cool and refrigerate the surrounding air through the evaporation and heat absorption of the cooling water inside the sponge plate 631, thereby further enhancing the cooling and heat dissipation effect on the LED full-color display module; Before the LED full-color display module starts working, the first diversion pipe 613 and the second diversion pipe 614 can be pushed towards the dehumidification mesh plate 10 through the threaded rod 617 and the sleeve rod 616, and the moving distance of the first diversion pipe 613 and the second diversion pipe 614 can be adjusted, so that the second connecting pipe 620 is driven to fit with the push block 634 on the connecting ring 632, and the connecting ring 632 can be pushed to move through the push block 634 until the connecting ring 632 fits with the first heat-conducting rod 11. Subsequently, when the exhaust fan 628 rotates, it can also drive each connecting rod 630 to rotate synchronously through the telescopic rod 629. At this time, under the rotation of each sponge plate 631 and the up-and-down reciprocating movement of the multi-stage heat dissipation assembly 6 as a whole, the cooling water can be evenly applied to each first heat-conducting rod 11. At this time, by the heat exchange between the first diversion pipe 613, the second diversion pipe 614, the first connecting pipe 619 and the second connecting pipe 620 and the air, and the evaporation heat absorption of the cooling water inside the sponge plate 631 and the evaporation heat absorption of the cooling water on each first heat-conducting rod 11, the heat conduction of the second heat-conducting rod 12 and the third heat-conducting rod 13 to the circuit board 14 can be combined, further improving the cooling efficiency and cooling effect of the LED full-color display module. In summary, by adjusting the multi-stage cooling intensity of the cooling structure according to the actual working environment and working intensity of the LED full-color display module, it can more flexibly cope with different working conditions, avoid overheating or overcooling, control the temperature of the LED full-color display module within a reasonable range, effectively slow down the aging speed of electronic components, extend the service life of the display module, reduce the maintenance cost and replacement frequency, and reduce energy consumption while improving the heat dissipation efficiency; During the air flow process, the filter screen plate 703 can stably filter the dust and impurities in the air, and when the mounting plate 5 moves up and down reciprocally, the third gear 706 can be driven to rotate automatically and reciprocally through the rack 707. Furthermore, the impurities and dust filtered on the filter screen plate 703 can be automatically cleaned by the scraping rod 705 on the connecting shaft 704, ensuring the stability of the filter screen plate 703 during long-term operation. And the cleaned dust and impurities can be automatically collected into the ventilation cylinder 702 for subsequent transfer and treatment to avoid environmental pollution; Before the LED full-color display module works, the staff can pull the pull plate 711 outwards. At this time, the pull plate 711 can drive the clamping rod 712 to move out of the clamping groove 708 on the ventilation cylinder 702, and then the ventilation cylinder 702 can be taken out of the positioning groove 701 to complete the disassembly of the ventilation cylinder 702. Subsequently, the staff can rotate and adjust the threaded rod 617 on the multi-stage heat dissipation assembly 6 according to the actual working environment, and the water can also be transported and fed through the feed pipe 604 on the second heat insulation box 603; after the LED full-color display module works, the subsequent transfer and treatment of the collected dust and the subsequent cleaning work of the filter screen plate 703 can be realized by disassembling the ventilation cylinder 702; When installing the ventilation duct 702, simply pull the pull plate 711 in advance, insert the ventilation duct 702 into the positioning groove 701, and then release the pull plate 711. At this time, under the elastic action of the second spring 710 on the connecting plate 709, the clamping rod 712 on the pull plate 711 can be automatically clamped into the clamping groove 708 on the ventilation duct 702 to complete the clamping and fixing of the ventilation duct 702, ensuring the stability of the subsequent working state of the ventilation duct 702.
