Carlo Gavazzi Computing Solutions in Brockton, Mass., is introducing the 715 series of re-circulating air-cooled rugged ATR enclosures for commercial off-the-shelf (COTS) printed circuit boards deployed in caustic environments with extremes in temperature, vibration, humidity, and contaminants. The 715 series has a re-circulating, air-cooling system that provides a contaminant-free environment for COTS convection-cooled cards. While functioning as a typical conduction-cooled system on the outside, the cooling solution for the 715 series uses a re-circulating fan on the inside to transfer circuit card heat to the conducting walls. The conducting walls are engineered thermal cores providing maximum heat transfer to the exterior surfaces of the system. For high-dust environments, the 715 series provides an advantage over conventional cooling methods because it does not draw outside air in to cool the system. Featuring a rugged, brazed aluminum frame construction, the 715 series is available with scalable power options and can be configured to custom form factor requirements for a variety of airborne and vetronics applications.
