The LED display will generate heat during use, especially the outdoor LED display. Because the environmental requirements they use are very high, it must be above 4000cd. The heat dissipation volume not only effectively improves the efficiency of the LED display's heat sores, but also achieves the effect of saving power. It is also conducive to improving the effectiveness of the LED display life and ensuring the display effect of the LED display. Increase the heat dissipation effect of the LED display, Xiaobian makes a brief introduction here.
1. Fan heat dissipation, and use long -lived and high -efficiency fans inside the lamp shell to strengthen heat dissipation. The more commonly used methods are low cost and effective.
2. Using aluminum heat dissipation fins, this is the most common method of heat dissipation. Use aluminum -sized heat fins as part of the shell to increase the heat dissipation area.
3. Integrated heat-conducting heat dissipation-the use of high-heat-conducting ceramics, the purpose of the cooling shell heat dissipation 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 our frequent metal heat conduction and the expansion coefficient of the heat dissipation material, The LED chip cannot be welded directly, so as to avoid high, low -temperature thermal stress damage to the chip of the LED display.
4. Drist the heat conduction pipe, and use the heating pipe technology to guide the heat from the LED display chip to the shell heat dissipation fin.
5. Airliofativity, using the shape of the lamp shell to create a convection air, which is a way to enhance the heat dissipation method of*cost.
6. Surface radiation heat dissipation treatment, radiation heat dissipation treatment on the surface of the lamp shell, the simpler is to apply radiation heat dissipation paint, which can bring the heat from the surface of the shell.
7. Plastic shell, fill in thermal conductive material when plastic shell injection plastic, thereby increasing plastic shell heat conduction and heat dissipation capabilities.
