Managing waste heat has always been a concern regarding electrical equipment. As technology has advanced over the last several decades, that concern has grown and evolved, especially as control panels and other systems continue to grow smaller. Fortunately, thermal management solutions have evolved right alongside the technology that they are meant to keep cool. Today, you have several choices for electrical cabinet cooling, as well as thermal management for systems and applications of all sizes.
Air conditioning is the oldest solution to managing electrical waste heat. Though air conditioners are effective, they also come with many drawbacks, such as excessive energy usage. Also, air conditioners contain Freon, which has been labeled as an ozone-depleting substance by the EPA.
Unlike air conditioning, compressed air cooling does not utilize Freon, and the equipment used to compress the air is more easily managed than air conditioners. As the name suggests, the coolers pump compressed air to transfer electrical waste heat away from sensitive electrical components. Though more reliable than air conditioners, air compressors are costly, and there is a risk of contaminants entering the electrical cabinet.
Ambient/Below-Ambient Heat Exchangers
Heat exchangers work similarly to compressed air in that their purpose is to dissipate heat, rather than eliminate it by chilling the air. The difference, however, is that heat exchangers do not use air compressors; they use natural or forced convection, and in some cases, phase-change cooling to help you significantly reduce operating costs.
