Do Air-to-Air Heat Exchangers Protect from Contamination?

Among their many benefits, heat exchangers provide the advantage of utilizing forces like natural or forced convection to make electrical thermal management much simpler and less costly. Without the need for clunky air conditioning equipment, heat exchangers can keep air within an electrical enclosure flowing to prevent heat pockets from forming. Yet, it may not be immediately obvious how air-to-air heat exchangers protect the enclosures they cool from contaminants in the air. The secret is that outside air is not part of an air-to-air heat exchanger’s operation. In fact, keeping outside air out is a significant reason why heat exchangers are so successful.

The Importance of Air-Tight Seals

In an air-to-air heat exchanger, heat is transferred away from electrical components using minimal or no external equipment, aside from one or a few small fans. The thermal energy that the air absorbs is transferred to another area of the heat exchanger, then released so that the air can be looped back to continue absorbing waste heat. For optimal results, the heat exchanger is designed using high-quality neoprene seals and gaskets that effectively keep the air outside of the unit from ever mixing with the air inside.

In addition to keeping the cooling unit operating efficiently, advanced seals also reduce the risks of contamination damaging sensitive electrical components. Dust, moisture, and more can lead to rusted or damaged electrical components, which results in increased needs for maintenance or equipment replacement. Therefore, the ability to protect electrical equipment from contamination is one of the most important benefits of modern heat exchangers.
