How to improve the heat dissipation of LED display
The LED display will generate heat during working. In practical applications, increasing the heat dissipation of the LED display not only effectively improves the efficiency of the display’s heat dissipation, but also saves power, which is more conducive to improving the life of the display. Long-term efficacy and ensure the display of the LED display, this article shares ways to improve the heat dissipation of the LED display!
1. Fans cooling, and high-efficiency fans are used inside the lamp housing to enhance heat dissipation. This is a common method with low cost and good results.
2. Use aluminum fins, which is a common way to dissipate heat. Use aluminum fins as a part of the shell to increase the heat dissipation area.
3. Integrated 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 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 soldered directly to avoid high and low temperature thermal stress from damaging the display chip.
4. Heat pipe thermal cooling, using heat pipe technology to conduct heat from the LED display chip to the shell heat dissipation fins.
5. Air fluid mechanics uses the shape of the lamp housing to create convective air, which is a cost-effective method of enhancing 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, which can 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.
