These seven methods can improve the cooling effect of LED display
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.
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.
Indoor LED display is used in indoor environment, the brightness requirement is not high, generally 600-1000CD, so the heat generated is not large, and in the summer, the room is basically air-conditioned, which has a great heat dissipation for the screen body. Benefits; LED transparent screen adopts light bar design, the flow of heat air naturally dissipates heat, and LED transparent screen is generally installed indoors for outdoor viewing, and indoor air conditioner also plays a big role in cooling. More than the need to apply more cooling methods is the outdoor LED display, outdoor LED display is generally installed, if the area is relatively large, the air conditioner is installed inside the screen to cool down.
