NISKAYUNA, N.Y. -- December 11, 2012

Adapted from technology that GE researchers originally developed for
commercial jet engines, GE (NYSE: GE) has announced a major technology
breakthrough, called DCJ, which adapts this technology for the cooling of
consumer electronics. DCJ will support the next generation of thinner, quieter
and more powerful tablets, laptops and other electronic devices. To view a

GE’s DCJ (Dual Piezoelectric Cooling Jets) behave as a micro-fluidic bellows
that provide high-velocity jets of air to cool electronic components. The
turbulent air flow of the DCJ increases the heat transfer rate to more than
ten times that of natural convection.

“DCJ was developed as an innovative way to dramatically reduce the amount of
pressure losses and loading characteristics in aircraft engines and power
generation in gas and wind turbines,” said Peter de Bock, lead Electronics
Cooling Researcher at GE Global Research. “Over the past 18 months we have
addressed many challenges adapting this technology in areas of acoustics,
vibration, and power consumption such that the DCJ can now be considered as an
optimal cooling solution for ultra-thin consumer electronics products.”

Compared to conventional cooling assemblies used in electronic devices today,
GE’s DCJ technology enables cooling solutions only 4mm tall, representing a
more than 50% decrease in height. In addition, the DCJ is very stingy on
power, consuming less than half the power of a comparable fan, and its simple
construction will deliver higher reliability leading to millions of dollars in
repair cost savings for OEMs.

“With new tablet and netbook roadmaps moving to platforms measuring less than
6mm high, it is clear that consumers are demanding thinner and more powerful
electronic devices,” said Chris Giovanniello, VP Microelectronics & Thermal
Business Development at GE Licensing. “GE’s patented DCJ technology not only
frees up precious space for system designers, but it consumes significantly
less power, allowing as much as 30 minutes of extra battery life. Best of all,
DCJ can be made so quiet that users won’t even know it’s running. Thermal
management is becoming a big problem for many companies trying to miniaturize
their electronics, and as a result we are getting strong demand to evaluate
the DCJ technology in many markets, from consumer electronics, to automotive,
to telecom and industrial sectors.”

GE is currently providing DCJ demonstration kits for OEMS wishing to evaluate
the DCJ technology for their next generation products. In addition, GE has
licensed the DCJ technology to Fujikura LTD, (www.fujikura.co.jp ) a world
leader in thermal management solutions, known for their reliable and
innovative products serving the telecom, automotive, energy, and electronics
markets.
