In practical applications, improving the heat dissipation of the LED display screen not only effectively increases the efficiency of the heat dissipation of the LED display screen, but also achieves the effect of saving electricity, and is more conducive to the improvement of the service life of the LED display screen.
1, the fan cooling, the lamp shell with long-lived high efficiency fan to enhance heat dissipation, the more commonly used method of this method is low cost, good effect.
2. Use aluminum heat sink fins, which is the most common method of heat dissipation. Use aluminum heat sink fins as part of the housing to increase the heat sink area.
3, air fluid mechanics, the use of the shape of the lamp shell, to create convection air, which is the most cost-effective way to enhance heat dissipation.
4, surface radiation heat treatment, the surface of the lamp shell to do radiation heat treatment, the more simple is to apply radiation heat radiation paint, heat can be taken away from the surface of the lamp shell.
5, integration of thermal conduction and heat dissipation - the use of high thermal conductivity ceramics, the purpose of cooling the lamp shell is to reduce the operating temperature of LED high-definition display chip, due to LED chip expansion coefficient and our common metal thermal conductivity, thermal expansion coefficient of expansion of the material gap, The LED chip cannot be directly soldered to avoid high and low temperature thermal stress destroying the LED display chip.
6, heat pipe heat dissipation, the use of heat pipe technology, the heat from the LED display chip to the shell cooling fins.
7, heat-conducting plastic shell, in the plastic shell filled with thermal conductivity material, so as to achieve increased thermal conductivity of the plastic shell, cooling capacity.
It can be seen that the maturity and progress of LED display heat dissipation technology will be beneficial to its conservation and environmental protection concepts. LED electronic display manufacturers in the LED display production, improve the LED display heat output in a variety of ways. There are different considerations depending on the size of the power and where it is used when dissipating heat.
