AMETEK Rotron has introduced the new Discus self-ventilating heat exchanger designed to cool sealed airborne or ground-based electronic and optical compartments without introducing contaminated external air.
Ideal for pod-mounted airborne optical systems, the Discus can also be used to 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 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 aluminum structure for maximum heat conduction, robustness and precise product dimensions.
The Discus system meets or exceeds the requirements of applicable US military and commercial aerospace specifications.
