When Are Below-Ambient Heat Exchangers Most Effective

Heat exchangers are commonly known for their ability to cool electrical enclosures to just above ambient temperatures, providing continuous thermal management with minimal effort. Sometimes, though, ambient temperatures can be higher than the maximum operating temperature of an electrical system, making ambient heat exchangers ineffective. In such cases, Noren can provide high-performance, below-ambient heat exchangers that offer the same efficiency and cost-effectiveness as ambient units by precisely controlling temperatures to meet the needs of a wide variety of applications.

Choosing Below-Ambient Heat Exchangers

These days, advanced technology has allowed virtually every industry to expand like never before, and many now operate in extreme climates with temperatures that are consistently high. To avoid excessively high costs of air conditioning to keep equipment from overheating, companies can ensure consistent, below-ambient cooling with air-to-water heat exchangers. Like ambient cooling units, below-ambient heat exchangers utilize natural forces to transfer electrical waste heat.

How They Work

Often designed as a closed loop system, an air-to-water heat exchanger takes advantage of a cooling fluid’s latent heat of vaporization to absorb the thermal energy that electrical components emit.  The fluid, usually water, can be set to the specific temperature needed, allowing for effective electrical cooling even in severely hot climates. In addition to high-temperature environments, air-to-water heat exchangers can often be ideal for locations where the level of contaminants in the air is especially high. Sensitive equipment in hazardous applications, such as oil and gas production, can be better protected by relying on below-ambient heat exchangers.
