FREMONT, Calif., 21 Aug. 2009. Elma Electronic Inc. in Fremont, Calif., is introducing a VPX, mil spec, electronic enclosure with conduction cooling.
The conduction cooled air transport rack (ATR) rugged enclosure for 6U VPX computer boards has a machined card cage that accommodates wedge locks to transfer heat from the boards to the machined platform walls within the integrated card guides. Special grade aluminum joined by a dip-braising process for the chassis parts ensures the best conductivity of the payload.
The COTS manufacturing approach for the ATR platform meets several military standards. Elma's design techniques meet MIL-STD 810, 461, 167, 901 and 704. The 6U VPX platform meets ARINC 404A, ARINC 600 and IEEE 1101.2 specifications and accepts 6U VPX boards compliant with VITA 46.x.
The ATR platform has a MIL 38999 power connector with an integrated line filter; the power supply and line filter combination are optimized to meet MIL-STD 461E and the aluminum dip-braised construction is designed to meet MIL-STD 810F for shock and vibration.
The mil grade components qualify the ATR platform to meet harsh military applications, specifically avionics applications which operate in high-altitude environments. The lightweight ATR platform is for applications where a lower weight is crucial. The -40 to 70 degrees Celsius operating temperature range, combined with cooling optimized via thermal simulation studies, allows for exceptional thermal performance.
Additional backplane options for the 7-slot conduction-cooled ATR platform include VME/64X, cPCI, VXS, MicroTCA and custom backplanes. The platform also has fixed mount devices, a 28 volts DC PSU input, and top-load card orientation. All removable covers are equipped with captive screws.
