Hybricon Corporation has released the liquid-cooled 1-ATR chassis, which is designed for applications using high power conduction cooled boards such as VITA 41 VXS and VITA 46. Traditional conduction cooled ATR chassis can handle boards that dissipate 20-40W per slot; however, today's airborne and ground vehicle signal processing applications such as electronic warfare, Elint, Sigint and electro-optical systems require higher levels of processing power and use boards that can generate over 90W of heat per slot. Liquid cooling provides a much better heat transfer mechanism to provide the cooling capacity required by the new generation of high performance boards.
Hybricon's liquid-cooled ATR has a demonstrated capability of cooling 100W per slot.
Hybricon's liquid-cooled ATR meets ARINC 404A/MIL-STD-91403 requirements.
It features brazed construction with liquid-cooled card cage sidewalls.
A variety of cooling fluids can be accommodated: PAO; ethylene glycol/water; propylene glycol/water; fluorinerts FC-75, FC-77, FC-104.
The high power configuration is capable of 800W for 1-ATR short or 1kW-plus for 1-ATR long.
A low pressure drop version is available (under 100mbar).
The top load 1-ATR short is available in a standard configuration with a nine-slot VITA 41 VXS or VME64x backplane and one power supply or a high power configuration with an eight-slot VITA 41 VXS or VME64x backplane and two power supplies.
The power supplies provide 28V DC input per MIL-STD704; single- and three-phase 115V AC 400Hz supplies are also available.
