How to improve the LED display heat dissipation
LED display in the use of the process will produce heat, especially outdoor LED display, because of its use of the environment requires a very high brightness, to be more than 4000CD, which produces heat is very large, in practice, improve the LED display heat dissipation, not only to effectively improve the efficiency of the LED display heat dissipation, but also to achieve the role of saving electricity, more conducive to improving the effectiveness of the LED display life and ensure the effect of LED display, then what are good ways to enhance the LED display heat dissipation, Jinhe photoelectric here to do a brief introduction. The efficacy of the service life of the LED display and ensure the display effect of the LED display, then what are the good ways to improve the LED display heat dissipation effect.
1, fan cooling, light shell with long life inside the efficient fan to enhance heat dissipation, the more commonly used method of this method of low cost, good results.
2, the use of aluminum cooling fins, this is the most common way of heat dissipation, with aluminum cooling fins as part of the shell to increase the heat dissipation area.
3, heat conduction and heat dissipation integration - the use of high thermal conductivity ceramics, the purpose of the lamp shell heat dissipation is to reduce the LED high-definition display chip operating temperature, due to the coefficient of expansion of the LED chip and we often have a large gap between the expansion coefficient of the metal thermal conductivity, heat dissipation materials, can not be directly welded to the LED chip, in order to avoid the high and low temperature thermal stresses damage to the chip of the LED display.
4, heat conduit cooling, the use of heat conduit technology, the heat from the LED display chip to the shell cooling fins.
5, air hydrodynamics, the use of light shell shape, creating convection air, which is * cost of enhanced heat dissipation methods.
6, surface radiation heat dissipation treatment, light shell surface radiation heat dissipation treatment, the simpler is to apply radiation heat paint, can be heat radiation way to take away from the surface of the light shell.
7, thermally conductive plastic shell, in the plastic shell injection molding filled with thermally conductive materials, so as to increase the plastic shell thermal conductivity, heat dissipation capacity.
Visible LED display heat dissipation technology maturity and progress will be conducive to its saving, environmental protection concept. LED electronic display manufacturers in the LED display production, improve the LED display heat dissipation methods. Heat dissipation based on the power size and the use of the place, there will be different considerations.
Indoor LED display used in indoor environments, brightness requirements are not high, generally in the 600-1000CD can be, so the heat generated is not large, and in the summer indoor are basically open air conditioning, for the heat dissipation of the screen body has a great benefit; LED transparent screen using light bar design, the flow of heat air natural heat dissipation, and the LED transparent screen is generally indoor installation of outdoor viewing, indoor Air conditioning also plays a big role in its cooling. Comparison of the need to apply more cooling methods is the outdoor LED display, outdoor LED display is generally installed, if the area is relatively large will be installed inside the screen body air conditioning for cooling.
