Hybricon's New Liquid-Cooled ATR Chassis Cools Up To 100 Watts Per Slot
Ayer, MA., January 16, 2006, Hybricon Corporation announces the release of a new 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 20-40 watts 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 utilize boards that can generate over 90 watts 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 100 watts 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 800 watts for 1 ATR short or 1000 plus watts for 1 ATR long. A low pressure drop version is available (under 1.5 psid).
The top load 1 ATR short is available in a standard configuration with a 9-slot VITA 41 VXS or VME64x backplane and 1 power supply or a high power configuration with an 8-slot VITA 41 VXS or VME64x backplane and 2 power supplies. The power supplies provide 28 VDC input per MIL-STD704; 1 and 3 phase 115VAC @400 Hz are also available.
Additional features include:
- Customizable I/O front bezel with Mil 38999 or other connectors
- MIL-STD-461 EMI
- Custom configurations and system integration services available
