LED displays are very common in our lives, used to display text, graphics, images, animations, etc. How to dissipate heat from the LED display when it is used for a long time? Today, the editor of YONGS LED display will tell you what are the cooling methods?

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 a more common heat dissipation method. Use aluminum heat dissipation fins as part of the shell to increase the heat dissipation area.

3. Air hydrodynamics, using the shape of the lamp housing to create convection air, which is a low-cost method to strengthen heat dissipation.

4. 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 radiate heat away from the surface of the lamp housing.

5. 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.

6. 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.

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.

8. 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 operating temperature of the LED display chip. Since the expansion coefficient of the LED chip is very different from the expansion coefficient of our usual metal thermal conductivity and heat dissipation materials, it cannot be Directly solder the LED chip to avoid high and low temperature thermal stress from damaging the LED display chip.
