As we all know, electronic equipment generates heat during use. If there is no good heat dissipation, its life will become shorter. The same is true for led displays. Both indoor and outdoor led displays face heat dissipation problems. So what are the ways to provide the heat dissipation capacity of the led display so that it can better serve us?

1. Fan heat dissipation. Use a long-life and high-efficiency fan inside the lamp housing to enhance heat dissipation. This is a relatively common method. This method has 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 the lamp shell for heat dissipation is to reduce the working 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.

4. Heat pipe heat dissipation, using heat pipe technology to conduct heat from the LED display chip to the shell heat sink fins.
5. Air fluid mechanics uses the shape of the lamp housing to create convective air, which is a cost-free 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.
