Heat Exchangers Designed for Below-Ambient Cooling

Since heat exchangers have become a popular electrical enclosure cooling system, the value of ambient cooling solutions has grown increasingly more prominent. However, there are still many applications in which ambient cooling doesn’t suffice, whether it’s because the environment outside of the electrical enclosures is too warm, or the application’s operating parameters specifically require below-ambient cooling. Fortunately, modern heat exchangers aren’t restricted to one form of cooling, and for many applications, they can be designed to achieve high-performance, below-ambient cooling with optimal efficiency.

When applications require below-ambient cooling

Ambient cooling methods first gained prominence as viable electrical thermal management solutions because of the significant benefits they provide in the cooling process. It involves keeping the temperatures inside of electrical enclosures at just above the ambient temperatures outside of them using natural heat transfer methods that use little energy and require little or no maintenance. For some applications, however, thermal management demands cooling that reaches temperatures well below the ambient temperatures outside of their enclosures. To achieve this, some companies still rely on traditional forms of chilling the inside of electrical enclosures, such as air conditioning and air compression units.

Turning heat exchangers into below-ambient solutions

Heat exchangers are designed to cool electrical enclosures with optimal efficiency, and today, that includes enclosures that only function properly with below-ambient cooling. The heat transfer techniques that heat exchangers utilize involve the use of an eco-friendly cooling fluid that flows through the inside of the heat exchanger. The fluid absorbs and transfer electrical waste heat before it can accumulate into heat pockets, and therefore, prevents the enclosure from overheating. By utilizing the right fluid, cooled the appropriate temperatures, heat exchangers can achieve the same highly efficient thermal management while keeping temperatures inside of enclosures well below the ambient temperatures outside of them.

How companies benefit from below-ambient heat exchangers

The benefits of ambient electrical cooling have been well-known for decades, but companies that utilize applications requiring below-ambient cooling have often felt compelled to continue relying on more traditional solutions. The ability to achieve below-ambient cooling using the same efficient, cost-effective methods as ambient cooling solutions has given increasingly more companies an important advantage. Heat exchangers operate on more natural and eco-friendly principles of transferring heat, which equates to significant savings in energy and maintenance, as well as several other more environmentally friendly processes.
