Hot weather improves the heat dissipation effect of outdoor LED display

Outdoor LED displays in hot weather have more stringent requirements for heat dissipation

1. The fan dissipates heat. The long-life and high-efficiency fan is used inside the lamp housing to enhance heat dissipation. The more commonly used method is low in cost and good in effect.

2. Use aluminum heat dissipation fins, which is the most common heat dissipation method. Use aluminum heat dissipation fins as part of the shell to increase the heat dissipation area.

3. Integration of thermal conductivity and heat dissipation – the use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp housing 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 thermal conductivity and heat dissipation materials. The LED chip cannot be directly welded, so as to avoid high and low temperature thermal stress damage to the LED display chip.

4. Heat dissipation by heat pipe, using heat pipe technology to conduct heat from the LED display chip to the heat dissipation fins of the shell.

5. Air hydrodynamics, using the shape of the lamp housing to create convection air, which is the most cost-effective way to strengthen heat dissipation.

6. Surface radiation heat dissipation treatment, the surface of the lamp housing is treated with radiation heat dissipation treatment. It is relatively simple 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 thermal conductive materials when the plastic shell is injection molded, so as to increase the thermal conductivity and heat dissipation capacity of the plastic shell.
