A Brief Look at How Heat Exchangers Work

The good thing about heat exchangers is that they can be crafted and adapted to fit virtually any electrical enclosure. Yet, every system is different, and therefore, heat exchangers must be designed in a variety of different ways to effectively meet each application’s needs. At Noren, our experts specialize in creating thermal management solutions that operate optimally in any given situation. For instance, our air-to-air and air-to-water heat exchangers are certified to operate in a diverse range of conditions, and are manufactured to continue working much longer than more traditional cabinet cooling methods.

Air-to-Air Heat Exchangers

Air-to-air heat exchangers are among the most common heat exchangers, and they operate on the basic principle that electrical equipment functions optimally as long as its waste heat isn’t allowed to accumulate. As the name suggests, air-to-air coolers use natural forces like conduction and natural/forced convection to transfer heated air away from electrical components. The waste heat is circulated to another area of the unit, such as a heat sink, where it can release the thermal energy it has absorbed. The cooled air is then recirculated through the heat exchanger to continue absorbing and transferring heat.

Air-to-Water Heat Exchangers

For clients who operate in particularly hot climates, where the ambient temperatures are too hot for electrical enclosures to operate, air-to-water heat exchangers are often the better choice. Like air-to-water units, they rely on natural forces to transfer heat rather than complex machinery to chill enclosures, such as air conditioners. Using water chilled to a specific temperature, air-to-water heat exchangers utilize phase-change technology in which the fluid absorbs thermal energy without a rise in temperature, causing it to evaporate. The vapor is circulated away from the electrical equipment, then condensed back into liquid and circulated in a continuous loop.
