New cooling technology will help make notebooks and tablets and are
General Electric has announced a new piezoelectric cooling solution for ultrathin tablets and laptop computers. The technology is called Dual Piezoelectric Cooling Jets or DCJ. The technology was adopted from cooling tech that GE uses to keep components inside commercial jet engines operating in cool.

The cooling device is 4 mm thick making it about 50% thinner than conventional cooling devices. The cooling technology acts like a micro-fluidic bellows to create high velocity and turbulent jets of cooling air. The turbulent flow of air creates a heat transfer rate more than 10 times that of natural convection.
General Electric believes that the thin design of the cooling device, which is about the thickness of a credit card, will help to enable the next generation of ultrathin tablets and notebooks with profiles of roughly 6 mm thick. The GE cooling technology also uses about half the electricity as a conventional cooling fan, which means longer battery life in portable devices.
