Description

Technical Field

[0001] The present invention relates to the technical field of backlight modules, and in particular to a high-heat dissipation LCD backlight module. Background Art

[0002] In the field of display technology, LCDs (liquid crystal displays) are widely used in computers, mobile phones, televisions, and measurement displays, thanks to their high resolution, low power consumption, and excellent visual experience. As a key component of LCDs, the backlight module (BLU) provides a stable and evenly distributed light source for the LCD panel, ensuring the LCD can display images properly and clearly. It plays a crucial role in the entire display system. With the continuous advancement of technology and the increasing demand for display quality from users, the performance optimization of LCD BLUs has received increasing attention, and heat dissipation has become a key factor restricting its further development.

[0003] At present, existing LCD backlight modules have many deficiencies in heat dissipation. Many backlight modules adopt traditional heat dissipation methods, such as simply opening heat dissipation holes. However, this method has low heat dissipation efficiency and cannot promptly dissipate the large amount of heat generated by the module during long-term operation. It fails to fully consider the heat conduction and convection paths, resulting in uneven heat dissipation and serious heat accumulation in some areas. This not only affects the overall performance of the backlight module, but also accelerates the aging of components such as optical film materials in the module, causing the film materials to curl due to heat, and then causing problems such as edge display abnormalities. Therefore, a high-heat dissipation LCD backlight module is proposed. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a high heat dissipation LCD backlight module with the following beneficial effects:

[0016] 1. This high-heat dissipation LCD backlight module forms a dual heat dissipation path by providing a circulating liquid cooling mechanism and a rotating ventilation mechanism. The liquid pump in the circulating liquid cooling mechanism drives the coolant through the second liquid guide hose into the liquid guide cavity of the limit plate. The heat generated by the lamp holder and the light-emitting lamp beads is quickly absorbed by the thermal conductivity of the limit plate. The heat is then returned to the hollow backlight plate through the first and third liquid guide hoses to complete the heat exchange. The air pump of the rotating ventilation mechanism transports gas through the air inlet pipe, enters the air guide plate through the air guide holes of the rotating shaft, and blows air evenly toward the bottom of the lamp holder through the air outlet pipe. The transmission belt drives the stirring blades on the rotating rod to disturb the air in the frame, accelerate the diffusion of heat to both sides, and discharge it through the air outlet channel and air outlet holes, significantly improving the heat dissipation efficiency.

[0017] 2. This high-heat dissipation LCD backlight module ensures heat dissipation stability by setting a limiting fixing mechanism and an installation support mechanism. The second spring and the second damper of the limiting fixing mechanism firmly clamp the lamp holder in the frame, ensuring that the limiting plate is in close contact with the lamp holder to efficiently conduct heat. The first spring and the first damper of the installation support mechanism buffer the impact of external vibration on the backlight panel and internal heat dissipation components, avoiding loose connections of liquid cooling pipes or ventilation components due to vibration. At the same time, the rotating shaft drives the air guide plate to rotate so that the airflow evenly covers the bottom of the lamp holder, solving the problem of local heat accumulation and ensuring uniform heat dissipation.

[0018] 3. This high-heat dissipation LCD backlight module enhances heat dissipation by providing an air intake processing mechanism and a refrigeration component. The processing cover of the air intake processing mechanism rotates with the rotating shaft, using the mesh to filter the incoming air. The scraper cleans impurities on the surface of the mesh in real time to prevent clogging. The refrigeration plate pre-cools the air entering the bottom box. The cold air flows through the air guide holes and aeration pipes of the rotating shaft into the backlight panel, reducing the temperature of the circulating coolant to improve heat absorption capacity. The one-way valve on the breather pipe balances the air pressure inside and outside the backlight panel to prevent the liquid cooling cycle from being affected by air pressure fluctuations, further enhancing heat dissipation performance.
