It’s a known fact that most, if not all, electronics operate best in cool, dry conditions.But the ture is most outdoor digital displays will be exposed to high ambient temperatures and direct sun-load at some point throughout the year. 

These same outdoor displays also need extra powerful backlights to produce 2500+ nits of brightness so they can be seen when the sun is shining. This additional backlight power adds to the existing heat load created by the sealed enclosure.

So when you factor in sun load, high ambient temperature, extra LED backlight heat, and a sealed enclosure you can understand that a robust cooling system isn’t just a nice feature to have, it’s an absolute necessity.

At present, Senpal uses three different ways to dissipate heat for our outdoor LCD display according to different applied enviroment. The first involves using air conditioners to blow cold air into the display cabinet, this approach works well for keeping things cool. The second approach to cooling involves simply using fans, vents and filters like in your household PC. The third approach is a dual-loop airflow system that uses a static heat exchanger to transfer heat out of the display chassis. 

Associating these approachs, all electronics are kept in a cool, dry and clean environment, which prolongs their life and significantly reduces field failures and associated maintenance costs.
