How to improve the cooling effect of LED display screen

LED display will produce heat in the process of use, especially outdoor LED display, because its use environment requires high brightness, brightness should be above 4000cd, so the heat generated is very large. In practical application, improving the heat dissipation of LED display is not only
LED display will produce heat in the process of use, especially outdoor LED display, because its use environment requires high brightness, brightness should be above 4000cd, so the heat generated is very large. In practical application, improving the heat dissipation of LED display can not only effectively improve the heat dissipation efficiency of LED display, but also achieve the effect of power saving, which is more conducive to improving the efficiency of LED display. Life and ensure the display effect of LED display.

Screen cooling effect method
Seven ways to improve the cooling effect of LED display screen:
1。 Fan cooling, long life and high efficiency fan inside the lamp shell is used to enhance heat dissipation. This method is more commonly used. This method has low cost and good effect.
2。 The most common method of heat dissipation is to use aluminum fins, which are used as part of the shell to increase the heat dissipation area.
3。 Combination of heat conduction and heat dissipation – using high heat conduction ceramics, the heat dissipation of lamp shell is to reduce the working temperature of LED high-definition display chip. Because the expansion coefficient of LED chip is very different from our usual metal heat conduction and heat dissipation materials, the LED display chip can not be directly welded to avoid high temperature and low temperature thermal stress damage to the LED display chip.
4。 Heat pipe is used to dissipate heat. Heat pipe technology is used to guide heat from LED display chip to heat sink of shell.
5。 Aerodynamics, using the shape of the lamp shell to produce convective air, is the most cost-effective method of heat dissipation.
6。 Surface radiation heat treatment. The surface of the lampshade is radiated. A simpler method is to use a radiant heat dissipation coating, which can remove heat from the surface of the lampshade by radiation.
7。 The heat conducting plastic shell is filled with heat conducting material during injection molding to increase the heat conductivity and heat dissipation capacity of the plastic shell.
