Selecting a cooling solution
Heat could affect or damage the electronics inside a cabinet. Some of this heat is dissipated through the cabinet walls. Depending on the size of the cabinet and the ambient temperature , this way of heat removal could be adequate for the application.
Another way of removing heat from a cabinet is by using Fresh Air Cooling. This could be Fresh air cooling.This could be accomplished with a combination of fans and filters. This type of thermal management solution may be used when the installation site is relatively clean and cool such as an office building or inside a cool telecom shelter.
When the electronics inside a cabinet need to be protected from contaminating elements, the recommended solution is to use a Closed-loop cooling system like a heat exchanger, a cabinet air conditioner or a thermo electronic cooler (Peltier). This is what is usually used in harsh environments such as outdoor applications in telecom BTS, oil rigs, substations and/or when temperature and humidity levels inside the enclosure are critical.
