An 8.8 pound sub-½ ATR, forced air-cooled enclosure for conduction-cooled modules is designed to reduce the Size, Weight and Power (SWaP) of deployed military systems. A fully populated XPand4200 from Extreme Engineering Solutions weighs less than 15 pounds and is suitable for C4ISR applications in vehicles such as UAVs, helicopters, planes, tanks and light armored vehicles, HMMWVs and UGVs. The XPand4200 conducts heat from conduction-cooled modules to heat exchangers, where the heat is dissipated to the ambient environment by forced-air cooling. Compared to similar systems, the cooling capability of the XPand4200 is significantly higher due to a heat exchanger integrated into the top of the unit. Because the design supports conduction-cooled boards in an air-tight enclosure, the XPand4200 provides enhanced shock and vibration protection and isolation of the boards from the outside environment.

The system measures 4.88” (W) x 6.0” (H) x 13.5” (D). The XPand4200 has an optional removable memory module attachment that supports the XPort6191 Solid State Disk (SSD) Removable Storage Module, with 64 Gbyte of storage capacity. With the memory module attachment the height increases to 7.62” and the weight to 11.1 pounds. Up to six conduction-cooled, 0.8” pitch 3U VPX, 3U cPCI, or power supply modules can be configured into the XPand4200. Additionally, the XPand4200 can be configured to meet custom I/O requirements with conduction-cooled PMC / XMC modules available from X-ES or third parties.

The XPand4200 supports Gigabit Ethernet, graphics, RS-232/RS-422, MIL-STD-1553, ARINC 429, as well as custom conduction-cooled PMC/XMC I/O through D38999 circular connectors. An optional front-panel USB port provides system monitoring and maintenance capabilities. There are several power supply options, supporting up to 200W from a MIL-STD-704 28V DC or 115V AC input, as well as internal EMI filtering and hold-up for up to 60 ms at 200W.
