GE Cooling Technology, As Thin As A Credit Card, Enables Ultra-thin Tablets, Laptops

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.

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, (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.

DOESNT WORK OHMAHGERD



looks like good tech, likely to end up in phones and tablets in the coming years.

Instead of natural convection, should it not be conduction?

no, they copy-paste press releases sent to them, as intended. sometimes personal comments get added in, but in general people dont like that being mixed with the news releases.

I have registered just to laugh at your intelligence. Look at the image before the headline. What does that say? Press release. Feel free to look up the meaning. EDIT: God damn it. I was beat. Darn registrations, foiled me again!

Don't think so...

You realize that's an oxymoron? Cheers Frick :clap:

This sounds great. Now we just need a breakthrough in the battery tech, they just can't hold enough juice. Cell phones need atleast 3000mah.

Read about that tech years ago — at least five. Nice to show it's finally going to be available to us consumers. =)

i hope these dont make laptops and stuff sound like jets :laugh:

technically, transfer of heat from a solid to a fluid is always predominantly convection.

didn't they had something like this years prior to this?

Interesting. On first look it seemed like a peltier, but this is a better option methinks. And from what I can tell, this one won't be as efficient as a proper heatsink/fan on its own, but would be a substantial improvement over a no heatsink/no fan environment like most phones use. That way you get some forced air cooling without making the case too thick or upping the power draw too much.

a peltier isn't new news.
No, but using one INSTEAD of a fan, and using it to REPLACE a fan IS new.

now that i look at the image again, isnt it just a teeny tiny subwoofer blowing air around? :/

gas/liquid = fluid on technical terminology :toast:
