Abstract
Description
Technical Field
[0001] This utility model relates to the field of LED screen technology, specifically to a heat dissipation structure for an LED display control box. Background Technology
[0002] LED displays have been widely used in modern industry. With the continuous expansion of market demand, the types of LED displays are also increasing, and their structures vary due to different installation requirements. Although there are many types of LED displays, their main components are basically the same, including LED modules, cabinets, control boxes, connectors, fasteners, and control systems.
[0003] The control box is a crucial component of an LED display screen. It typically houses electrical components such as a hub board, power supply, receiver card, wiring harness, and cooling fan. Upon power-on, these components generate heat due to the load. As the control box is an enclosed space, its internal temperature rises rapidly within a short period. The power supply and receiver card are the primary heat sources, each with a rated operating temperature. When the temperature exceeds these temperatures, the power supply and receiver card will malfunction or even fail, resulting in a distorted or black screen on the LED display. Therefore, heat dissipation of the control box is a critical issue that urgently needs to be addressed.
[0004] The common heat dissipation method for control boxes is to transfer the heat generated by high-heat electrical components to the outside environment as quickly as possible. For example, thermal pads or thermal grease are added between the power supply and the box body. Heat is transferred from the power supply to the box body via the thermal pads or grease, and then from the box body to the external environment through airflow over its outer surface. However, control boxes are usually coated with powder or other coatings, which significantly reduce heat conduction efficiency. Therefore, many LED display manufacturers only offer warranties of 1-2 years. To improve heat dissipation efficiency and extend product lifespan, it is necessary to research and invent an LED enclosure and control box with dedicated heat dissipation functions to solve the above problems. Utility Model Content

[0029] Example:
[0030] like Figure 1-5 As shown, this embodiment provides a heat dissipation structure for an LED display control box, including a housing 1. Several LED modules 2 are detachably and fixedly installed on the front of the housing 1 in an array pattern. A cross-shaped support rib 101 is provided in the middle of the housing 1, and a control box 4 is provided in the middle of the support rib 101.
[0031] The control box 4 includes a cover 401 and a body 403. The cover 401 and the body 403 are fastened together by bolts. Multiple heat dissipation copper pipes 6 are fixedly installed in a row inside the cover 401. An air inlet 402 is fixedly installed at one end of the body 403. A cooling fan 5 is fixedly installed on the air inlet surface of the air inlet 402 through a bracket.
[0032] The control assembly 7 is fixedly installed inside the housing 403. The control assembly 7 includes a hub board 704, and a turbine fan 705 is welded to the front of the hub board 704.
[0033] In a preferred embodiment of the present invention, the front side of the Hub board 704 is further welded with a TB terminal block 701, a receiver card 702, and a switching power supply 703.
[0034] In a preferred embodiment of the present invention, a plurality of plug-in modules 706 are evenly arranged on the back of the Hub board 704, and a module socket 404 is provided on the back of the housing 403 corresponding to each plug-in module 706. The module socket 404 is connected to the inside of the housing 403, and the plug-in module 706 is correspondingly disposed inside the module socket 404.
[0035] In a preferred embodiment of this utility model, a communication outlet 707, a power outlet 708, and a fan outlet 709 are fixedly installed on the left and right sides of the bottom of the box 403.
[0036] In a preferred embodiment of this utility model, the heat dissipation copper pipe 6 further includes a pipe body 602, both ends of which are movably connected with locking nuts 604. Both ends of the inner wall of the cover 401 and the corresponding ends of each pipe body 602 are riveted with nut connectors 601. The pipe body 602 is threadedly connected to the corresponding nut connectors 601 through the locking nuts 604.
[0037] Specifically, such as Figure 1-4 As shown, four mounting ears are provided on the upper and lower edges of the back of the box 403. Each mounting ear has a Ø10.5mm mounting hole, which corresponds to the M10 screw holes on the box 1. Eight module sockets 404 are provided on the back of the box 403. Sockets on the hub board 704 extend from the module sockets 404 and interlock with the module sockets 404 on the back of the modules. Twenty-one M8 threaded holes are provided on both sides of the cover 401. Nut connectors 601 connect to the screw holes from inside the control box 4, and O-ring seals 603 seal the nut connectors 601 and the box 403. The bottom of the box 403 has inlet and outlet holes for installing communication inlet, power inlet, fan outlet 709, power outlet 708, and communication outlet 707, respectively. The enclosure is equipped with press-fit studs for securing the Hub board 704, switching power supply 703, receiver card 702, TB terminal, turbine fan 705, etc. Twenty-one copper heat dissipation pipes 6 are installed inside the cover 401. The copper pipes 602 have flared ends on both sides and are secured to the nut connector 601 with locking nuts 604. The copper pipes are flexible, and when the copper nuts are tightened to the copper pipe nut connector 601, the flared ends of the copper pipes are pressed against the chamfered surface at the end of the copper pipe nut connector 601, providing a good seal. Two M10 screw holes are provided on one side of the cover 401 for securing the air inlet 402. The cover 401 and the enclosure 403 are secured with three sets of stainless steel hinges and three sets of stainless steel buckles. A sealing strip is installed between the cover 401 and the enclosure 403.
[0038] According to the above structural configuration, the heat generated by the electrical components is quickly conducted to the environment inside the box by the turbine fan 705 inside the box 403, so that the temperature rise of the heat-generating electrical components is effectively controlled. Because the turbine fan 705 is always working, the temperature inside the box is relatively uniform, and the heat can be quickly transferred to the surface of the copper tube 602.
[0039] The cooling fan 5, installed on one side of the enclosure 1 near the air inlet 402 of the control box 4, blows cold air (-40℃~+45℃) from the external environment into the heat dissipation copper pipe 6. The cold air in the pipe 602 quickly absorbs the heat from the pipe wall and transfers it to the external environment. In this way, the heat inside the power supply box is continuously conducted to the external environment through multiple copper pipes 602, which plays a cooling role and extends the service life of electrical components.
[0040] In a preferred embodiment of the present invention, a sealing ring 603 is further provided between the nut connector 601 and the inner wall of the cover 401.
[0041] In a preferred embodiment of the present invention, both ends of the tube body 602 are further provided as flared openings, and the shape of the flared openings of the tube body 602 matches the chamfer shape of the inner hole of the locking nut 604.
[0042] Specifically, such as Figure 4 As shown, the tube body 602 of the heat dissipation copper tube 6 is flared on both sides and fixed with locking nuts 604 and nut connectors 601. The copper tube is soft and can press the flared ends of the tube body 602 against the chamfered surface of the end of the copper tube nut connector 601 when the locking nuts 604 and nut connectors 601 are tightened, thus achieving a good sealing effect.
[0043] In a preferred embodiment of the present invention, a bolt lock 3 and a bolt seat 8 are respectively provided on opposite sides of the box body 1, and two adjacent boxes 1 are locked together by bolt lock 3 and bolt seat 8.
[0044] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
