There are many ways to improve the heat dissipation of the LED display. Cooling according to the size of the power and the use of places, there will be different considerations, the following from eight aspects of the introduction.
1, air fluid mechanics, the use of light shell shape, to create convection air, which is the lowest cost to strengthen the cooling method.
2, the fan cooling, lamp shell with longevity efficient fan to enhance the heat, the more commonly used method This method is low cost, good effect.
3, the use of aluminum cooling fins, which is the most common way of cooling, with aluminum cooling fins as part of the shell to increase the cooling area.
4, the surface of radiation heat treatment, light shell surface to do radiation heat treatment, the more simple is the application of radiation cooling paint, heat can be taken away from the light shell surface.
5, heat pipe cooling, the use of heat pipe technology, the heat from the LED display chip leads to the shell cooling fins. This method is also used in large lamps, such as LED lights.
6, thermal plastic shell, plastic packaging in the plastic filler when filling materials, so as to increase the plastic shell thermal conductivity, cooling capacity.
7, the use of liquid bulb packaging technology, the higher the thermal conductivity of the transparent liquid filled into the bulb within the lamp body.
8, heat and heat integration - the use of high thermal conductivity ceramic, lamp shell cooling is to reduce the LED display chip operating temperature, due to LED chip expansion coefficient and our constant thermal conductivity of metal, thermal expansion coefficient of the gap between the large, The LED chip directly welded to avoid high and low temperature thermal stress damage LED display chip.
Effectively improve the LED display heat can be achieved to save power and improve the efficiency of LED display life.
