Heat exchanger from AMETEK Rotron cools sealed electronics without contaminated outside air
WOODSTOCK, N.Y., 24 April 2014. AMETEK Rotron in Woodstock, N.Y., is introducing the Discus Self Ventilating Heat Exchanger (SVHE) that cools sealed airborne or ground-based electronic and optical compartments without introducing contaminated external air.
Designed for pod-mounted airborne optical systems, the Discus also can cool other aircraft, helicopter, drone, and ground-based electronics requiring air segregation.
The product has two separate airflow channels with active induced air circulation via an integrated set of motorized 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 aluminum pin fins.
A 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 one homogenous aluminum structure for maximum heat conduction, robustness and precise product dimensions.
The Discus system meets or exceeds the requirements of applicable U.S. military and commercial aerospace specifications, company officials say.
