Summer is the biggest challenge for outdoor LED displays. Humid and high-temperature weather makes the natural contradiction between moisture resistance and heat dissipation of LED displays head-on. How to do a good job of preventing moisture in rainy weather while maintaining good heat dissipation in a high temperature environment has become a thorny issue facing outdoor LED displays. In the hot and humid weather, facing moisture and heat dissipation, this seemingly irreconcilable contradiction can actually be solved ingeniously through exquisite hardware and elaborate structural design. First of all, reducing LED display power consumption and reducing heat loss are effective ways to improve heat dissipation. Selecting high-quality LED display chips from the source for optimized design, focusing on the independent research and development of high-efficiency and high-quality drive power, outstanding raw material quality and excellent performance parameters have laid a firm foundation for heat dissipation and moisture resistance. Furthermore, improving the production process of LED display modules is also a top priority. It is understood that the structure of the electronic components on the PCB board is optimized to simplify and rationally arrange, and use high thermal conductivity materials to fill and seal, while meeting the seamless entry of water vapor and the heat dissipation requirements of the components. The internal components of the LED display are MSD components (humidity sensitive components). Once moisture enters, it may cause oxidation and corrosion of components such as lamp beads, PCB boards, power supplies, and power cords, resulting in dead light failures. Therefore, the module, internal structure and external chassis of the LED display screen need to be thoroughly and tightly moisture-proof and waterproof. At the same time, the internal components of the full-color LED display are also the most heat-generating electronic components, such as LED lamp beads, driver ICs, and switching power supplies. Poor heat dissipation design will oxidize the screen material, affecting quality and life. If the heat accumulates and cannot be dissipated, the internal components of the LED will overheat and be damaged, causing malfunctions. Therefore, good heat dissipation requires a transparent and convective structure, which contradicts the requirements of moisture resistance. Reasonable optimization of outdoor LED display box structure can play a key role. Considering the heat dissipation and oxidation resistance of the chassis material, high-quality aluminum is selected. The interior of the chassis adopts a multi-layer space structure to form an overall transparent and convective heat dissipation structure, which can make full use of natural air for convection heat dissipation, which takes into account both heat dissipation and sealing. , It also improves reliability and service life.
