LED display heat dissipation technology and seven tips to increase heat dissipation
In practical applications, increasing the heat dissipation of the LED display not only effectively improves the efficiency of the heat dissipation of the LED display, but also saves power, and is more conducive to improving the life of the LED display.
1. The fan is used to dissipate heat. A long-life and high-efficiency fan is 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 of heat dissipation. Use aluminum fins as part of the shell to increase the heat dissipation area.
3. Aerodynamics uses the shape of the lamp housing to create convective air, which is the lowest cost method of enhancing heat dissipation.
4. 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, which can take the heat away from the surface of the lamp housing by radiation.
5. 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 operating temperature of the LED high-definition display chip, because the expansion coefficient of the LED chip is very different from the expansion coefficient of our usual metal heat conduction and heat dissipation materials. The LED chip cannot be directly soldered to avoid high and low temperature thermal stress from damaging the LED display chip.
6. Heat pipe heat dissipation, using heat pipe technology to conduct heat from the LED display chip to the shell radiating fins.
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.
