Humidity and high temperatures allow LED screens to combat moisture and heat, a natural contradiction.How to do moisture-proof work in rainy weather, while keeping good heat dissipation in a high temperature environment, has become a thorny problem faced by outdoor LED screens.
Moisture and heat, a natural contradiction
The internal components of LED display screen belong to MSD components (humidity sensitive components). Once moisture enters, it may cause oxidation corrosion of zero components such as lamp beads, PCB board, power supply, power cord and so on, thus causing dead lamp failure.Therefore, the modules, internal structure and external chassis of the LED screen need to be fully and strictly moisture-proof and waterproof.
At the same time, the internal components of the LED screen are also electronic components that generate much heat, such as LED lamp beads, drive IC, switching power supply, etc.Poor heat dissipation design will make the screen material oxidation, affect the quality and life.If the heat accumulates and does not dissipate, it will lead to the LED internal components overheating and damage, leading to failure.Therefore, good heat dissipation requires a transparent, convective structure, which contradicts the requirements of moisture.
Hot and humid, how to do both
Into the hot and humid weather, in the face of moisture and heat dissipation, this seemingly irreconcilable contradiction, in fact, it can be skillfully resolved through superb hardware and careful structural design.
Firstly, reducing power consumption and heat loss is an effective way to improve the heat dissipation capacity.
Furthermore, improving the production process of modules is also a top priority.
Finally, reasonable optimization of box structure can play a key role.Considering the heat dissipation and oxidation resistance of the chassis material, high-quality aluminum is selected. The chassis interior adopts a multi-layer space structure to form an overall convection cooling structure, which can make full use of natural air for convective cooling, giving consideration to both heat dissipation and sealing, and improving reliability and service life.
