Electronics Enclosure Targeted for Demanding Military Applications

Electronics Enclosures

Cooling Technology Changes How Electronics are Deployed in Harsh Environments

LIBERTY LAKE, Wash.--Parker Aerospace, a developer of advanced thermal management components for the military, has launched the first in a planned series of enclosures that are intended to change the way that electronics are deployed in harsh military environments. The company's Multi-Platform Enclosure (MPE) employs the patented SprayCool® two-phase cooling technology, a space-saving innovation that cools electronics through the evaporation of a fine mist of non-corrosive, non-conductive liquid. Benefits of the MPE are said to include the flexibility to deploy legacy or proprietary electronics with commercial-grade electronics in the same enclosure. And by accepting electronics cards designed for air or conduction cooling with minimal modifications, the MPE is said to reduce costs and permit faster development cycles for integrators and their military customers.

According to Parker Aerospace, its two-phase cooling technology provides "a climate-controlled environment to cool any electronics in a package that is significantly smaller, lighter, and more power- and cost-efficient." The controlled operating environment of the MPE "enables all electronics to operate effectively in the military's most demanding environments," the company says.

"SprayCool's patented two-phase liquid cooling system means customers can package significantly more electronics capability into a smaller, lighter, more power-efficient enclosure, and do it much more quickly," said Matt Gerber, Parker Aerospace president and chief executive officer, in a statement released by the company. "This unique capability has resulted in the award of several significant military contracts for our MPE this year."

The MPE has already been selected by prime integrators Lockheed Martin and Northrop Grumman for DoD programs involving radar and image processing electronic warfare applications. It's also being considered for a number of other airborne and land-based applications, the company reported.

The SprayCool process begins by spraying--in a thin layer--a fine mist of non-corrosive, non-conductive liquid. As the mist evaporates, it cools the electronics. By continuously cycling within a sealed, closed loop system, the process isolates the electronics from dirty, corrosive environments found in military and industrial applications. The result, the company says, is cooler, higher-performance, and more durable electronic devices.

The MPE enclosure can scale from 4 slots to 21 slots and is designed to meet industry standard designs for 6U x 160mm VME-64X, VPX, VXS, cPCI and CPCIe(EXP.0) and proprietary electronics boards. It is said to offer significantly more cooling capability per slot (above 300 Watts) than enclosures using older cooling technologies, such as air or conduction cooling. In addition, the SprayCool MPE accommodates a wide variety of customer-specified I/O options. Its operating environment can range from -65°C to +71°C, and up to 100,000 feet in altitude in unpressurized compartments. The MPE meets or exceeds MIL-STD-810 and MIL-STD-461 requirements for harsh environments, the company says.

According to the company, the SprayCool MPE is well-suited for the challenges facing today's integrators and system designers that need to package more processing power into an existing or smaller space. Because the MPE accepts a broad variety of cards, system integrators no longer need to wait to deploy the latest in electronic solutions. Current applications for the MPE include image and radar processing, command and control, and EW jamming systems in unmanned aircraft (ASIP Program), helicopters, fixed-wing aircraft, and ground-based vehicles.

Parker Aerospace says that the MPE base model, configurable enclosure is a result of the company's "extensive experience and development of custom solutions for the military that have been tested and fielded to meet or exceed the most severe military standards for vibration, shock, EMI, sand, dust, salt fog, salt water immersion, altitude, and temperature."
