Today, we're going to introduce what are the hot dissaption measures for outdoor advertising display, and we listed several ways of it, as following:
1. Fan heat dissipation, lamp housing with longevity and high efficiency fan to strengthen heat dissipation, the more commonly used method of this method is low cost, good effect.
2. Air fluid mechanics, the use of lamp shell shape, to produce convective air, which is the most cost to strengthen the heat dissipation method.
3. The use of aluminum fin, which is the most common way of heat dissipation, with aluminum fin as part of the shell to increase the heat dissipation area.
4. Heat conduction tube heat dissipation, the use of heat conduction tube technology, the heat from the LED display chip to the shell heat dissipation fin.
5. Thermal conductive plastic shell is filled with thermal conductive material when plastic shell is injected, so as to increase the thermal conductivity and heat dissipation ability of plastic shell.
6. The surface radiation heat treatment, the surface of the lamp shell radiation heat treatment, the relatively simple is to apply radiation heat dissipation paint, can radiate the heat away from the surface of the lamp shell.
7. The use of heat integration of thermal conductivity, high thermal conductivity of ceramic, lamp shell cooling purpose is to reduce the working temperature of the led display chip, due to the led chip we often metal thermal conductivity, thermal expansion coefficient and material expansion coefficient difference is very big, the led chip can not be directly welding, also avoid the high and low temperature thermal stress damage led display chip, and so on.
