The LED full-color display will generate heat during use, especially outdoors, because it needs high brightness during use, and the brightness should be above 4000CD, so it generates a lot of heat. In practical applications, improving the heat dissipation performance of the LED full-color display can not only effectively improve the heat dissipation efficiency of the LED full-color display, but also save power. Thereby, the service life of the LED full-color display is increased, and the display effect of the LED full-color display is ensured.
LED full color display
Ways to improve the heat dissipation performance of LED full-color display:
1. Fan cooling device. The long-life, high-efficiency fan in the lamp housing enhances the heat dissipation effect. This method has low cost and good effect. 2. The LED full-color display adopts aluminum heat sink, which is very common for heat dissipation. The use of heat-dissipating aluminum fins as a part of the chassis increases the heat-dissipating area.
3. High thermal conductivity ceramics are used for heat dissipation. The main purpose of the lamp shell for heat dissipation is to reduce the operating temperature of the LED high-definition display chip, and the expansion coefficient of the LED chip is different from our metal thermal and heat dissipation materials. The LED chip cannot be welded directly, avoiding the damage of high and low temperature stress to the LED full-color display chip.
4. Heat pipe heat dissipation, heat pipe heat dissipation is used to output the heat of the LED full-color display chip to the body heat sink.
5. Surface radiation heat dissipation, the surface of the lamp housing uses radiation to dissipate heat. The simplest method is to use radiant heat-dissipating paint, which can output heat from the surface of the lampshade of the LED full-color display through radiation.
6. When the shell is injection molded, the thermal plastic shell is filled with thermally conductive material to improve the heat conduction and heat dissipation capabilities.
