1. The fan dissipates heat, and the inside of the lamp housing uses a long-life and high-efficiency fan to enhance heat dissipation. The commonly used method has low cost and good effect.

2, the use of aluminum fins, this is the most common way to dissipate heat, using aluminum fins as part of the shell to increase the heat dissipation area.

3, heat conduction and heat dissipation integration - 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 high-definition display chip, because the LED chip expansion coefficient and our common metal heat conduction, heat dissipation material expansion coefficient is very different, The LED chip cannot be directly soldered to prevent high and low temperature thermal stress from damaging the chip of the LED display.

4, the heat pipe heat dissipation, using the heat pipe technology, the heat is led from the LED display chip to the shell heat sink fins.

5, air fluid mechanics, the use of the shape of the lamp housing, to create convective air, which is * cost of enhanced cooling methods.

6, surface radiation heat treatment, the surface of the lamp shell to do radiation heat treatment, the simpler is to apply radiation heat sink paint, you can radiate heat away from the lamp shell surface.

7. The heat-conducting plastic shell is filled with the heat-conducting material during the injection molding of the plastic shell, thereby increasing the heat-conducting and heat-dissipating ability of the plastic shell.

It can be seen that the maturity and progress of LED display cooling technology will be conducive to its conservation and environmental protection concept. LED electronic display manufacturers in the LED display production, there are many ways to improve the heat dissipation of LED display. There are different considerations depending on the power level and the place of use when dissipating heat.
