GE Cooling Technology, As Thin As A Credit Card, Enables Ultra-thin Tablets, Laptops
NISKAYUNA, N.Y. --(Business Wire)--
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 demonstration of the technology, -click

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 stingyon 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.
