New Line of Heat Exchangers Use Energy-Efficient Thermodynamics to Cool Electrical and Electronic Enclosures

HE units are used to draw heated air from the cabinet, thermodynamically cool it, and then return the cooled air to the cabinet.

EIC Solutions, Inc., a leading manufacturer of thermoelectric air conditioners, electronic enclosures and transit cases, has announced the release of its HE Series Heat Exchangers. Providing energy-efficient cooling for electrical and electronic enclosures, HE Series units have no moving parts except fans making them an economical, low maintenance solution.

HE Series Heat Exchangers are designed to cool electrical and electronic enclosures, cabinets and panels in installations where enclosed equipment may be safely maintained and operated at temperatures several degrees above the ambient temperature outside the cabinet. Likely installation sites include air conditioned buildings and lower temperature indoor/outdoor sites where electrical and electronic components may need cooling to function properly. HE heat exchangers are used to cool medical devices, food/beverage process controls, telecom equipment, computers, security equipment and other electronics and electrical devices housed in cabinets/enclosures.

Even in low temperatures, electrical devices and electronic components generate heat which increases air temperature inside an enclosure. If left unchecked, internal enclosure temperatures can reach potentially damaging levels. HE units are used to draw heated air from the cabinet, thermodynamically cool it, and then return the cooled air to the cabinet. This process can cool cabinet interiors to within 5 degrees Fahrenheit above the ambient air temperature outside the enclosure. Furthermore, HE units do not allow outside air to enter the enclosure or mix with the enclosure air. This protects contents from possible contamination by dirt or dust which could cause sensitive electronics and electrical devices to malfunction or become damaged

“Heat exchangers are an ideal solution for many applications,” said Josh Liegel, EIC senior sales engineer, “because they remove waste heat from cabinets and panels without letting contaminants enter the enclosure.” Liegel said the HE Series is a cost-effective and efficient solution that can be quickly implemented without modifying the existing configuration of the components within the enclosure. Liegel also said, “the sleek design of the HE Series Heat Exchangers facilitates installation on existing cabinets, even in close spaces.”

Liegel explained that the heat exchangers enable efficient cooling of cabinets and enclosures with only a minimal increase in energy consumption in keeping with current trends for more energy efficient construction and equipment. “Heat exchangers use less energy than air conditioners,” said Liegel, “so when a limited amount of cooling is needed, the HE units meet cooling requirements without taxing energy budgets.”

HE Heat Exchangers employ a powerful fan to draw heated air from the cabinet and force it across a heat-absorbing core. As the heat is absorbed from the air stream, thermal dynamic principles cause the heat to transfer to the ambient side of the core. A fan on the ambient side then moves cool ambient air across the core. The cool air absorbs the heat and is dissipated as exhaust from the heat exchanger. The newly cooled air is then re-circulated back into the cabinet which lowers the interior cabinet temperature. At no time does the cabinet air contact the outside or ambient air.

HE Series units are available in a wide range of sizes to provide from 5.7 to 83 watts/degree Fahrenheit of closed-loop heat removal capacity. Made from durable 16-gauge welded steel, HE Series Heat Exchangers mount on the side of electronic enclosures and maintain NEMA type 12, 3R, 4, or 4X ratings. An epoxy coated aluminum core provides excellent corrosion resistance. Options include 24/48 VDC and 120/230 VAC power options, Type 304 stainless steel NEMA 4X construction and either a 4 or 10 micron ambient side intake air filter.
