Seven skills to improve the heat dissipation of LED display screen
In practical application, improving the heat dissipation of LED display can not only effectively improve the efficiency of heat dissipation of LED display, but also achieve the effect of saving electricity, which is more conducive to improving the service life of LED display.
1. Fan heat dissipation, lamp shell interior with a long life high-efficiency fan to strengthen heat dissipation, the more commonly used method of low cost, good effect.
2. Use of aluminum fins, which is the most common way of heat dissipation, aluminum fins as part of the shell to increase the area of heat dissipation.
3. Aerodynamics, the use of lamp shell shape, to create convective air, which is the lowest cost method to enhance heat dissipation.
4. Surface radiation heat dissipation treatment, lamp shell surface radiation heat dissipation treatment, more simple is to apply radiation heat dissipation paint, heat can be radiated away from the lamp shell surface.
5. Integration of heat conduction and heat dissipation--The application of high thermal conductivity ceramics. The purpose of heat dissipation of lamp shell is to reduce the operating temperature of LED high-definition display chip. Because the expansion coefficient of LED chip is very different from that of our usual metal thermal conductivity and heat dissipation material, it is impossible to weld LED chip directly so as to avoid high and low temperature thermal stress destroying LED display. Screen chip.
6. Heat pipe heat dissipation, the use of heat pipe technology, the heat from the LED display chip to the shell fin heat dissipation.
7. Thermal conductive plastic shell is filled with quotient thermal conductive material when plastic shell is injected, so as to increase thermal conductivity and heat dissipation capacity of plastic shell.
Visible LED display cooling technology maturity and progress will be conducive to its conservation, environmental protection concept. LED electronic display manufacturers in the production of LED display screen, improve the heat dissipation of LED display in a variety of ways. Heat dissipation depends on power and location.
