Curtiss-Wright Controls Announces CoolWall(TM) Enclosure Thermal Management Technology Breakthrough

LITTLETON, MA - December 17, 2010 - Curtiss-Wright Controls Electronic Systems, a
business group of Curtiss-Wright Controls and a leading designer and manufacturer of rugged
deployed subsystems for the aerospace and defense market, has announced that recent testing
of its new (patent pending) CoolWall(TM) technology for thermal management of rugged
embedded computing enclosures has shown a greater than 2x improvement in payload power
cooling when compared to traditional aluminum construction. In addition, this breakthrough
technology, based on a proprietary mixture of metal composite materials, delivers its
dramatically higher thermal conductivity at a weight significantly lighter than aluminum. The
ability to thermally manage higher power payloads is critical in leading edge multiprocessing
and DSP applications using new products such as VPX where space, weight, and power
(SWaP)-constraints are key design hurdles. CoolWall technology can be used both to improve
thermal performance and reduce weight. Electronic Systems plans to make this advanced
cooling technology available to the embedded market in a broad line of Hybricon® engineered
packaging solutions.

Recent test results of CoolWall technology, using the company's baseplate-cooled Hybricon
SFF-6 enclosure, showed a 2.4x increase in thermal conductivity at the chassis level (2.4x
decrease in sidewall temperature rise) along with a 10% weight decrease as compared to
aluminum construction. The initial test results showed a 9°C (approximate) temperature rise of
the chassis rails at 67W/slot power dissipation. The CoolWall technology utilizes a mixture of
metal composites to deliver enhanced thermal performance combined with the structural
characteristics required for rugged applications. The technology comprises a unique thermal
metallic composite core housed within a structural metallic composite shell.
"Electronic Systems' Hybricon CoolWall thermal management technology represents a real
breakthrough in chassis design," said David Dietz, vice president and general manager of
Curtiss-Wright Controls Electronic Systems group. "Using CoolWall, system integrators can
achieve maximum performance in a low weight, small form factor rugged enclosure. It
significantly outperforms aluminum at similar price-points, and matches copper at significantly
less weight and cost. We are just beginning to explore the potential of this important new
packaging technology. Electronic Systems plans further refinements to the technology that
promise to deliver continual improvements in cooling performance."

Although the initial testing was performed on a prototype enclosure using a cold plate, the use
of CoolWall technology is not limited to cold plate applications. It offers the potential to enhance
the weight and thermal performance of natural convection-cooled, forced air conduction-cooled,
or liquid conduction-cooled chassis through superior heat spreading. To address a variety of
requirements, CoolWall technology can be flexibly optimized to modify the balance of its
optimization of thermal management or weight reduction.

In addition, CoolWall technology can be used in the design of embedded computing modules to,
for example, enhance the thermal performance of conduction-cooled module thermal frames by
providing superior heat spreading without the added weight of copper.
