Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for display modules, specifically to an outdoor high-brightness liquid crystal display module with a multi-layer heat dissipation fin combination. Background Technology

[0002] Outdoor high-brightness LCD display modules are widely used in outdoor advertising screens, traffic guidance screens, and outdoor public information display screens due to their high brightness and high definition, providing people with clear and intuitive information display. However, due to the complex and changeable outdoor environment, especially in high-temperature environments, display modules will generate a lot of heat during long-term operation. If the heat cannot be dissipated in time, it will lead to a decline in the performance of the liquid crystal material and accelerated aging of electronic components, thereby affecting the display effect and the lifespan of the module. Therefore, efficient heat dissipation design is crucial to ensuring the stable operation of outdoor high-brightness LCD display modules.

[0003] Currently, traditional outdoor high-brightness LCD display modules have problems with heat dissipation and fixing. In terms of fixing structure, they mostly use screw fixing or simple clip connection, which makes the installation process cumbersome and makes it difficult to achieve quick disassembly and expansion of the module. In terms of heat dissipation, they usually rely on a single heat sink or simple ventilation holes, which have limited heat dissipation area and low air convection efficiency, and cannot meet the heat dissipation requirements in outdoor high-temperature environments. These defects not only increase the installation and maintenance costs, but also make us propose an outdoor high-brightness LCD display module with a multi-layer heat dissipation fin combination.

Multiple heat dissipation modules can be stacked through the multi-layer positioning holes 10 to ensure the module position is fixed.

The heat dissipation component composed of the heat dissipation fin plate 2 and the serpentine fins 3 plays a key role. The serpentine fins 3 on the front and back of the heat dissipation fin plate 2 are distributed in multiple equidistant positions. The serpentine structure increases the heat dissipation area and allows for more full contact with the air. When the display module generates heat during operation, the heat is transferred to the heat dissipation fin plate 2 and then diffused through the serpentine fins 3. The vent holes 12 distributed equidistantly at the four ends of the fixing frame 4, together with the exhaust holes on the back protective cover 1 and the air circulation cavity between the fixing frame 4 and the protective cover 1, form a 4-layer air convection channel. Cold air from the outside enters through the vent holes 12, flows through the heat dissipation fin plate 2 and the serpentine fins 3 to carry away the heat, and hot air is discharged from the exhaust holes of the protective cover 1, achieving efficient heat dissipation and ensuring the stable operation of the outdoor high-brightness LCD display module in complex environments.
