Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-3This utility model discloses a heat dissipation structure for an LED display screen, including a display screen housing 1 and a heat dissipation component 2. The back of the display screen housing 1 is provided with a connection window 11. The heat dissipation component 2 is installed at the connection window 11 by screws. An aluminum substrate 12 is installed inside the display screen housing 1 by screws. A heat dissipation plate 13 is fixedly installed on the back of the aluminum substrate 12. The assembly adopts a split type. The connection window 11 is opened on the back of the display screen housing 1, and the heat dissipation component 2 is installed through the connection window 11. The aluminum substrate 12 is set inside the display screen housing 1, and the heat dissipation plate 13 is attached to it. The heat dissipation component 2 is attached to the heat dissipation plate 13. During heat dissipation, the aluminum substrate 12 and the heat dissipation plate 13 act as heat conduction medium to conduct the heat generated by the circuit board to the heat dissipation component 2 for heat dissipation. Without affecting the heat dissipation effect, it is convenient to disassemble, replace or maintain the heat dissipation component 2, saving time and effort.

[0021] The heat dissipation assembly 2 includes an assembly box 21, an axial fan 22, an aluminum extruded heat sink 23, an ear bracket 24, and an adapter 25. The back of the assembly box 21 is provided with heat dissipation holes 26. The axial fan 22 is installed inside the assembly box 21, and the air inlet end of the axial fan 22 is connected to the aluminum extruded heat sink 23. The aluminum extruded heat sink 23 is attached to the heat spreader 13. The ear bracket 24 is hinged to the back of the cavity by a pin. The adapter 25 is hinged to the ear bracket 24 by a pin. Since the ear bracket 24, the assembly box 21, and the adapter 25 in the heat dissipation assembly 2 are assembled by hinges, the rear half of the heat dissipation assembly 2 can be used as an adjustment support with a support column to facilitate the angle adjustment of the display screen, thus making it more convenient to use.

[0022] Specifically, the display screen housing 1 has air inlets 14 on both sides, and the air inlets 14 are located on the back of the display screen housing 1.

[0023] In this embodiment, under the action of the axial fan 22, fresh air is introduced through the air inlet 14 and hot air is discharged through the heat dissipation hole 26.

[0024] Specifically, the assembly box 21 is provided with fixing holes 27, and the fixing holes 27 are located around it.

[0025] In this embodiment, the fixing hole 27 is an installation structure used to fix the assembly box 21 to the connection window 11 with screws.

[0026] Specifically, the heat dissipation hole 26 corresponds to the position of the axial fan 22, and the heat dissipation surface of the aluminum extruded heat sink 23 is in contact with the axial fan 22.

[0027] In this embodiment, the aluminum substrate 12 and the heat spreader 13 serve as heat conduction media to transfer the heat generated by the circuit board to the aluminum extruded heat sink 23. An axial fan 22 generates airflow to carry away the heat from the surface of the aluminum extruded heat sink 23.

[0028] Specifically, the heat transfer surface of the aluminum extruded heat sink 23 extends from the connection window 11 into the display screen housing 1 and is attached to the heat spreader 13 through a thermally conductive silicone sheet.

[0029] In this embodiment, the aluminum extruded heat sink 23 has excellent thermal conductivity, which can quickly conduct heat from the heat source to the heat sink, and greatly improve the heat dissipation efficiency through the convection heat transfer between the heat sink and the air.

[0030] Specifically, the heat spreader 13 is bonded to the aluminum substrate 12 with thermal paste, and the display screen housing 1 is provided with an internal threaded post 15, and the aluminum substrate 12 is fixed to the internal threaded post 15 with screws.

[0031] In this embodiment, the aluminum substrate 12 is a mounting component used for mounting and fixing the circuit board inside the display screen, and the heat dissipation plate 13 can efficiently and evenly distribute heat, avoid local overheating, and improve the overall heat dissipation efficiency.

[0032] In use, a split assembly is adopted. A connection window 11 is opened on the back of the display screen housing 1, and the heat dissipation component 2 is installed through the connection window 11. An aluminum substrate 12 is set inside the display screen housing 1, and a heat dissipation plate 13 is attached to it. The heat dissipation component 2 is attached to the heat dissipation plate 13. During heat dissipation, the aluminum substrate 12 and the heat dissipation plate 13 act as heat conduction medium to conduct the heat generated by the circuit board to the heat dissipation component 2 for heat dissipation. Without affecting the heat dissipation effect, it is convenient to disassemble, replace or maintain the heat dissipation component 2, saving time and effort. Since the ear seat 24, the assembly box 21 and the adapter seat 25 in the heat dissipation component 2 are assembled in a hinged form, the rear half of the heat dissipation component 2 can be used as an adjustment support with a support column to facilitate the angle adjustment of the display screen, thus making it more convenient to use.

[0033] In summary, this heat dissipation structure for LED displays adopts a split assembly form. A connection window 11 is opened on the back of the display housing 1, through which the heat dissipation component 2 is installed. An aluminum substrate 12 is set inside the display housing 1, and a heat dissipation plate 13 is attached to it. The heat dissipation component 2 is attached to the heat dissipation plate 13. During heat dissipation, the aluminum substrate 12 and the heat dissipation plate 13 act as heat conduction mediums to conduct the heat generated by the circuit board to the heat dissipation component 2 for heat dissipation. Without affecting the heat dissipation effect, it is convenient to disassemble, replace or maintain the heat dissipation component 2, saving time and effort. Since the ear seat 24, the assembly box 21 and the adapter seat 25 in the heat dissipation component 2 are assembled in a hinged form, the rear half of the heat dissipation component 2 can be used as an adjustment support with a support column to facilitate the angle adjustment of the display screen, thus making it more convenient to use.
