How does led screen deal with heat dissipation

As we all know, led screen is divided into indoor led screen, outdoor led screen, led full color screen, monochrome led screen, picture and text led screen.Since the led screen is an electrical appliance, with power supply and components, it will definitely generate heat.So what‘s the right temperature for heat, and what‘s the right temperature for a large led screen to keep.Let‘s focus on the following for reference.

The common led strip screen usually does not need to be equipped with heat dissipation equipment, because the led strip screen is not high and long, and the usually installed led modules are semi-outdoor modules, so there is no need to heat dissipation treatment due to the gap heat can be directly dissipated.

Indoor monochrome led screen also does not need heat dissipation, because indoor monochrome led screen module is magnetic absorption type, there are gaps between modules and modules, the heat can be directly dispersed, so there is no need to install heat dissipation equipment.

Outdoor led large screen must be installed cooling equipment.Outdoor led screen has these characteristics, first of all, waterproof is very important, outdoor led large screen installed on the column, hanging on the outside wall of the building, some Mosaic installation, sealing must be very tight, or water or moisture, will lead to poor contact led screen circuit lead to short circuit risk.Secondly, outdoor led large screen brightness is high, the brightness must be greater than the illumination to display a clear picture, which means that the power of indoor led large screen power is larger, the power of the heat generated is also large, so outdoor full-color led large screen must be installed heat dissipation equipment.Some people say that it is not necessary to install, if not installed, the main impact is the high temperature inside the screen body, will lead to early aging screen body components, life shorter.And led screen in the short term will also appear IC breakdown risk.

Heat dissipation equipment has 2 ways, the first, led screen area is less than 20 square meters, with the convection fan can be installed outside the shutter, so as to avoid rain into the screen body inside.More than 20 square meters, air conditioning should be installed to cool down, the average 20 square meters of led screen 1 2P air conditioning, so 100 square meters of led large screen will be installed 5 2P air conditioning.
