This year is undoubtedly the time of the outdoor LED screen (challenge the largest, humid and high temperature weather to LED screen moisture and heat the natural contradictions of the positive confrontation.How to do in the rainy weather moisture work, while In the high temperature environment to maintain good heat dissipation, outdoor LED screen has become a difficult problem facing.
Moisture and heat, a pair of natural contradictions
LED display internal devices are MSD components (humidity sensitive devices), once the moisture may cause the lamp beads, PCB board, power supply, power lines and other parts of the oxidation of corrosion, resulting in dead light failure. So the LED screen module, the internal structure and external chassis need to do a thorough and tight moisture, waterproof design.
At the same time LED panel internal device is also the most heat of electronic components, such as LED lamp beads, driver IC, switching power supply. Poor thermal design will make the screen material oxidation, affecting quality and life. If the heat is collected and can not let go, will lead to LED internal device overheating and damage, causing failure. Therefore, good heat dissipation requires a transparent, convective structure, which contradicts the requirements of moisture protection.
Hot and humid, how to achieve a two-pronged approach
Into the hot and humid weather, the face of moisture and heat, which seem irreconcilable contradictions, but in fact can be superb hardware and careful structural design cleverly resolved.
First of all, reduce power consumption, reduce heat loss is an effective way to enhance the cooling capacity.
Moreover, to improve the module production process, is also the most important.
Finally, the rational optimization of the box structure, can play a key role. In the chassis material to consider the heat dissipation and oxidation of choice of high-quality aluminum, the chassis internal multi-storey space structure, the formation of the overall transparent convection cooling structure, will be able to make full use of natural air convection heat, both thermal and sealing , But also improve the reliability and service life.
