 LED display will generate heat during use, especially for outdoor LED display. Because the environment used for it requires very high brightness, it should be above 4000CD, so the heat generated is very large. In practical applications, the LED display is improved. The heat dissipation not only effectively improves the efficiency of the heat dissipation of the LED display, but also saves the power, and is more conducive to improving the service life of the LED display and ensuring the display effect of the LED display. What are the good methods? Improve the heat dissipation effect of the led display,How should outdoor LED display heat dissipation be done?
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 working temperature of the LED display chip, because the LED chip expansion coefficient and our common metal heat conduction, heat dissipation material expansion coefficient is very large, can not The LED chip is 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 the LED display cooling technology will be conducive to its conservation and environmental protection concept. There are various ways to increase the heat dissipation of the LED display. There are different considerations depending on the power level and the place of use when dissipating heat.
