When heat exchangers were first introduced as an industrial solution for cooling electrical enclosures and control panels, their most notable benefit was their ability to prevent electrical overheating by simply redirecting heat. As long as a system’s maximum operating temperature was lower than the ambient temperature outside of the enclosure, transferring waste heat away from sensitive components was enough to keep the system functioning at optimum capacity. However, applications where the ambient temperature is too high or the level of waste heat emitted is too overwhelming for ambient cooling need a more powerful solution. With below-ambient heat exchangers, such applications can still benefit from the more affordable, efficient, and reliable thermal management processes that heat exchangers provide.
When Chilling Enclosures Is Necessary
There are many reasons why ambient cooling won’t suffice for certain systems. For instance, operations that take place in extremely hot climates can reach temperatures that exceed even average maximum operating temperatures. In some cases, the application itself may generate so much electrical waste heat and at such a rapid pace that ambient cooling simply won’t work. Therefore, many companies and designers believe that air conditioning is still necessary, even though below-ambient heat exchangers can provide the high-performance thermal management solutions they need.
Eliminating the Need for Air Conditioners
Like ambient heat exchangers, their below-ambient counterparts utilize natural methods of heat transfer to prevent electrical overheating. The difference, however, is that below-ambient units contain a cooling fluid that is cooled to the specific temperature dictated by the system’s requirements. The fluid ensures that temperatures remain well below ambient when necessary, all without the need to rely on air conditioning equipment.
