In practical applications, improve the heat dissipation of the LED display, not only effectively improve the efficiency of LED display heat, you can also achieve the role of saving electricity, more conducive to improving the efficiency of LED display life. How can effectively improve the heat of the LED display it,
1, the use of fan cooling, lamp shell with longevity efficient fan to enhance the heat, the more commonly used method This method is low cost, good effect.
2, 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.
3, air fluid mechanics, the use of light shell shape, to create convection air, which is the lowest cost to strengthen the cooling method.
4, the surface of radiation heat treatment, lamp 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, thermal integration of heat - the use of high thermal conductivity ceramic, lamp shell cooling is to reduce the high-definition display chip chip operating temperature, due to the expansion coefficient of LED chips and our metal thermal conductivity, thermal expansion coefficient of great difference, LED chip can not be welded directly to avoid high and low temperature thermal stress damage LED display chip.
6, heat pipe cooling, the use of heat pipe technology, the heat from the LED display chip led to the shell cooling fins.
7, thermal plastic shell, plastic injection molding in the plastic material, so as to achieve an increase in plastic shell thermal conductivity, cooling capacity.
This shows that LED display cooling technology mature and progress will be conducive to its conservation, environmental protection concept. LED electronic display manufacturers in the LED display production, improve the LED display heat a variety of ways. Cooling power based on the size and use of places, there will be different considerations.
