How to cooling led display?

Shenzhen Lights Technology Co.,Ltd | Updated: Mar 21, 2016

In practice, the increase in heat dissipation LED display, LED display not only effectively improve the heat dissipation efficiency can achieve power saving effect, more conducive to improving the effectiveness of the service life of the LED display.


1, cooling fan, the lamp envelope to strengthen the internal cooling fan with long life and efficient, this method is more commonly used method of low cost, good effect.

2, the use of aluminum fins, which is the most common heat sinks, aluminum fins as part of the housing to increase the cooling area.

3, the air fluid dynamics, the use of the lamp envelope shape, create a convection air, which is the lowest cost method to enhance heat dissipation.

4, surface radiation heat treatment, surface light shell made radiation cooling process is relatively simple applicator radiation heat paint, radiant heat mode can be removed from the surface of the lamp envelope.

5, thermal heat integration - the use of high thermal conductivity ceramic, the purpose is to reduce heat dissipation lamp shell led HD display chip operating temperatures due to LED chip expansion coefficient and we often metal thermal conductivity, thermal expansion coefficient of the material differ greatly, LED chip can not be soldered directly, in order to avoid high and low temperature thermal stress damage the LED display chip.

6, thermal pipe cooling using a heat exchanger tube technology, the heat generated by the LED display chip lead into the housing fins.

7, thermal plastic case, at the time of injection molding plastic shell filled with a thermally conductive material suppliers, so as to increase the plastic shell thermal conductivity, thermal capacity.


Visible LED screen cooling technology matures and its progress will be conducive to saving, environmentally friendly LED electronic display manufacturers in the production of LED display, LED display method for improving heat dissipation varied. When the cooling power based on the size and use of premises, they have different considerations.
