Elma Creates Liquid-Cooled Air Transport Rack Chassis

Elma Electronic Inc., a global manufacturer of electronic packaging products, has announced a new liquid-cooled ATR (air transport rack) chassis that is modular. The unit can be configured in various sizes and configurations without starting from scratch, which saves time, effort, and money.

The liquid cooled ATR chassis can fit up to ten 6U x 160mm slots in a 1 ATR Short size. Designed to ARINC 404A, the chassis accepts conduction-cooled modules in various architectures such as VME/64x, cPCI, VXS, VPX, and more. The independent dual liquid-cooled sidewalls dissipate in excess of 100 Watts per slot. Various cooling fluids can be used including glycol, kerosene, PAO, salt water, etc. With a proven high-integrity frame construction, the unit is highly ruggedized and meets MIL-STD 810E, 461D and 704E.

Elma Liquid-Cooled ATR EnclosureWith a modular design, the ATR can be designed in various configurations. The chassis can easily be scaled up or down while using the same liquid-cooled sidewalls (i.e., the walls for a 1 ATR are the same as the ones for a 1/2 ATR). To reduce costs, the liquid cooling can be optionally limited to one sidewall. Various plug-in power supply modules and front I/O configurations are possible in this design. Elma also offers a wide selection of backplanes in various architectures and has different milled card cage sizes off-the-shelf.

The unit is power via 28V DC/270V or optionally 1 and 3-phase 115VAC @ 400Hz. The liquid-cooled chassis can take up to 1 KW of input power. Custom I/O solutions are optional including MIL-STD wiring and connectors. Elma also offers ATR chassis in several sizes for convection (forced air), conduction, and hybrid cooled applications.

The lead-time is 6-8 weeks.
