Outdoor LED displays in hot weather have stricter requirements for heat dissipation. Here, Shenzhen Liansen Optoelectronics LED display manufacturer tells several ways to improve the heat dissipation effect of outdoor LED displays:
1. Fan heat dissipation, long-life and high-efficiency fans are used inside the lamp housing to enhance heat dissipation. This is a common method with low cost and good effect.
2. Use aluminum fins, which is the most common way to dissipate heat. Use aluminum fins as part of the housing to increase the heat dissipation area.
3. Integration of heat conduction and heat dissipation-the use of high thermal conductivity ceramics, the purpose of lamp housing heat dissipation is to reduce the working temperature of the LED high-definition display chip, due to the gap between the expansion coefficient of the LED chip and our usual metal heat conduction and heat dissipation materials The LED chip cannot be directly welded to avoid high and low temperature thermal stress damage the LED display chip.
4. Heat pipe heat dissipation, using heat pipe technology to conduct heat from the LED display chip to the heat dissipation fins of the shell.
5. Aerodynamics, using the shape of the lamp housing to create convective air, which is the most cost-effective method of heat dissipation.
6. Surface radiation heat dissipation treatment, the surface of the lamp housing is treated with radiation heat dissipation. The simpler is to apply radiation heat dissipation paint to take the heat away from the surface of the lamp housing by radiation.
7. The thermally conductive plastic shell is filled with thermally conductive material when the plastic shell is injection molded, so as to increase the thermal conductivity and heat dissipation capacity of the plastic shell.
