Eurosatory 2014

A cool throw (ES14E1)

16 June 2014

AMETEK Rotron (Hall 5, Stand B707) has introduced a thermal management product, which cools sealed airborne or ground-based electronic and optical compartments without introducing contaminated external air.

Designed specifically for pod-mounted airborne optical systems, but also suitable for aircraft, helicopter, drone and ground-based electronics requiring air segregation, the new Discus self-ventilating heat exchanger offers greater cooling capability and reduced weight compared with previous technologies.

The product has two separate airflow channels with active induced air circulation via an integrated set of motorised impellers, keeping compartment air separate from the external cooling air. Heat transfer occurs by convection from the circulating air and then by conduction through a common bulkhead connecting two sets of integrated aluminium pin fins.

A single brushless DC motor turns two impellers on a common shaft, each circulating air past the exposed pin fin exchanger surface. The mounting bracket, common bulkhead and both sets of pin fins are all incorporated into a single homogenous aluminium structure for maximum heat conduction, robustness and precise product dimensions.

AMETEK Rotron produces brushless DC motors, blowers and pumps for aerospace, military, mass-transit, medical and computer applications.

It is a unit of AMETEK Inc, a global manufacturer of electronic instruments and electromechanical devices, which has annual sales of $3.6 billion.
