Flexible and Reliable Air-to-Air Cooling Solutions

Air-to-air heat exchangers from Aavid Thermacore provide reliable thermal performance for cooling electronics within enclosures — with minimized cost and small component size.

HEX air-to-air heat exhangers

If you need dependable electronics cooling for increasingly miniaturized components within enclosures, or for demanding applications like telecommunications or military/aerospace where weather can be a factor, turn to Aavid Thermacore air-to-air heat exchangers. These heat exchangers rely on passive heat pipe or folded fin impingement cores to transfer the heat within the electronic enclosures to the outside ambient air for rejection.

Aavid Thermacore heat exchanger cores can be customized to accommodate different power loads and different air velocities in the ambient and internal loops.

HX® Series Compact Heat Exchangers

hx series air-to-air heat exchangerNeed cost-effective cooling for enclosed electronic equipment with high heat loads? Aavid Thermacore's HX Series compact heat exchangers use passive two-phase heat pipe technology with energy-efficient fans to give you high performance at low cost — plus unsurpassed reliability and reduced noise. The HX maintains the integrity of enclosures through a flange and closed-cell neoprene gasket between the interior and exterior heat exchangers.

Design flexibility and application versatility are integral to the HX concept. Multiple packaging options are available for various applications, and product design can easily be scaled to fit any thermal capacity. HX heat exchangers are easily adapted to custom applications. Mounting options for electronic enclosures include:

  • External (doors, side, top or back)
  • Internal
  • Partially recessed
  • Captured within ductwork
  • Side mounted
  • Submersible with soldered manifold plate
  • Environmental protection coatings (chromate, nickel plating, etc.)

HXi® Series Heat Exchangers

HXi series air-to-air heat exchangerImprove heat transfer performance and meet design requirements for small size and low cost by relying on Aavid Thermacore HXi Series air-to-air heat exchangers. These reliable thermal solutions use double-sided impingement technology to give you better heat dissipation performance than any competitive heat exchanger of comparable size. That makes the HXi Series a cost-effective and high-performance alternative to conventional heat exchangers — with fewer moving parts for maximum reliability.

Standard units are available with 2, 4, 6 or 8 fans, and custom optional features such as alarms and temperature controls are also available. Performance data for the standard HXi Series heat exchangers are given in the graph below. The HXi Series is UL recognized and meets Bellcore GR-487-CORE, NEMA 4 and NEMA 12 requirements.
