Over the past several decades, heat exchangers have significantly impacted the thermal management process of companies in all industries. They’ve done this by giving companies better, more natural, and more efficient ways of preventing electrical overheating, which don’t rely on cumbersome processes like condensing and/or chilling air. In many cases, the ambient cooling techniques used by heat exchangers provide more than adequate solutions for keeping most modern applications properly cooled. However, applications that require below-ambient cooling have also benefited just as significantly from the efficient and eco-friendly processes provided by modern heat exchangers.

Differences between ambient and below-ambient cooling
Below-ambient cooling brings the temperatures inside an electrical enclosure well below the ambient temperature outside. For older electrical cooling solutions, this was the norm. Air conditioners and air compressing units were designed to chill air and circulate it within a given electrical enclosure. Traditional heat exchanger designs changed this by transferring waste heat instead of chilling the inside of an electrical enclosure, making ambient cooling a more efficient alternative. However, many applications still require cooling to below-ambient temperatures to meet their unique operating parameters.

The challenges of below-ambient cooling
Even as heat exchangers were transforming the concepts of modern electrical cooling, many companies still believed they had no choice but to rely on older thermal management systems due to their needs for below-ambient cooling. It wasn’t long, however, that heat exchanger designers met this need by customizing their heat transfer processes to provide below-ambient cooling. This can include utilizing an eco-friendly cooling fluid chilled to the appropriate temperature and keeping the temperature inside an electrical enclosure consistently.

Natural methods for below-ambient heat transfer
Modern heat exchangers can meet below-ambient and ambient electrical cooling needs with equal efficiency and productivity, significantly boosting the thermal management capabilities of many different companies. While promoting more effective and efficient below-ambient cooling, heat exchangers also help companies boost their success in other areas, such as implementing greener and more eco-friendly operations. Their simplified and customizable designs make ambient and below-ambient heat exchangers the preferred solution for increasingly more applications.
