Seven tips on heat dissipation of LED display screen
In practical application, the heat dissipation of the rental screen of the forward LED display is not only useful for the power dissipation of the rental screen of the forward LED display, but also can save electricity, which is more conducive to the effect of the service life of the rental screen of the forward LED display. So how to forward the LED display screen to dissipate heat? Here are seven tips:
1. The electric fan is used for heat dissipation, and the long-life and high-efficiency electric fan is used for heat dissipation inside the lamp shell. This method has low cost and good effect.
2. Using aluminum fins, which is the most common way of heat dissipation, uses aluminum fins as part of the shell to add heat dissipation area.
3. Air hydrodynamics, the use of lamp shell shape, to create convective air, which is the lowest cost way to strengthen heat dissipation.
4. Surface radiation heat treatment, the lamp shell surface radiation heat treatment, the more simple is to apply radiation paint, can take the heat away from the lamp shell surface by radiation method.
5. With the integration of heat conduction and heat dissipation and the application of high thermal conductivity ceramics, the purpose of lamp shell heat dissipation is to reduce the working temperature of LED high-definition display chip. Because the expansion coefficient of LED chip is far away from our usual metal heat conduction and heat dissipation data, the LED chip cannot be directly welded to avoid high and low temperature thermal stress damaging the chip of LED display screen.
6. The heat pipe is used to dissipate heat. The heat is transferred from the LED display screen chip to the shell fin by using the heat pipe skill.
7. The heat conductive plastic shell is filled with heat conductive data when the plastic shell is injected, and then the heat conduction and heat dissipation of the plastic shell are added.
It can be seen that the LED display panel rental panel cooling skills of sophisticated and forward will be conducive to its saving, environmental protection concept. LED electronic display manufacturers in LED display rental screen manufacturing, LED display rental screen forward a variety of ways to dissipate heat. When cooling, there will be different considerations according to the size of power and the place of application
