Some tips to improve the heat dissipation of PCB for LED display

Abstract: LEDs can be seen everywhere, so what are the techniques for heat dissipation? In practical applications, increasing the heat dissipation of the PCB for LED display not only effectively improves the efficiency of the heat dissipation of the LED display, but also saves power, and is more conducive to improving the life of the LED display.

PCB for LED display

1. Use fan cooling PCB for LED display

A long-life and high-efficiency fan is used inside the lamp housing to enhance heat dissipation. This is a common method with low cost and good effect.

2. Utilize aluminum cooling fins

This is the most common way to dissipate heat. Aluminum fins are used as part of the housing to increase the heat dissipation area.

3. Air fluid mechanics

Air fluid mechanics uses the shape of the lamp housing to create convective air, which is the lowest cost method of enhancing heat dissipation.

 

4. Surface radiation heat dissipation treatment

The surface of the lamp shell is treated with radiation heat dissipation. The simpler is to apply radiation heat dissipation paint, which can take the heat away from the surface of the lamp shell by radiation.

5. Integrated heat and heat dissipation

The use of high thermal conductivity ceramics, the purpose of heat dissipation of the lamp shell is to reduce the working temperature of the LED high-definition display chip. Since the expansion coefficient of the LED chip is very different from the expansion coefficient of our usual metal heat conduction and heat dissipation materials, the LED chip cannot be directly welded to avoid High and low temperature thermal stress damages the PCB for LED display chip.

 

6. Heat pipe heat dissipation

Using heat pipe technology, the heat is conducted from the led display pcb board chip to the heat dissipation fins of the shell.

7. Thermally conductive plastic shell

When the plastic shell is injected, the thermal conductivity material is filled to increase the thermal conductivity and heat dissipation capacity of the plastic shell.

8. Summary

It can be seen that the maturity and progress of LED display heat dissipation technology will be conducive to its saving and environmental protection concepts. LED electronic display manufacturers have a variety of methods to improve the heat dissipation of LED displays in the production of led display pcb board. Depending on the power level and the place of use, different considerations will be applied to the heat dissipation.

To meet the high reliability requirements of PCB for LED display products, manufacturers need to spend more time and more energy to develop in this area. I believe that the technology of the LED display industry will become more and more sophisticated in the future, and the development will Unlimited.
