[Extremetech] GE develops ultra-thin, almost-silent cooler for next-gen laptops and tablets

General Electric has unveiled what seems to be the thinnest, high-performance cooler for the next-generation of ultra-thin tablets and laptops (pictured above). While this cooler obviously allows for slimmer designs (or more space for other components), it also uses just half the power of a comparable fan, granting a significant boost to battery life. Oh, it’s almost silent, too.

The technology behind GE’s cooler is called DCJ — Dual Piezoelectric Cooling Jets. DCJ basically acts as a miniature pair of bellows: Expanding to suck in cool air, and then contracting to expel hot air. GE originally invented DCJ to help cool commercial jet engines, but two years ago it seems someone had the clever idea of miniaturizing the tech for use in computers — and so here we are.

Looks to be a very interesting development, will certainly have the ability to reduce form factor on various devices.

Nice replacement for fans.... but I wonder the CFM and air pressure these are capable of?

Note: These themselves are NOT "coolers".

I just don't see that moving enough air for a laptop or anything...but I can see it allowing for more powerful processors in tablets and smart phones.

Though right now there isn't any fans on them...how is this 50% thinner than something. Or are there some small devices with tiny fans on them?

Not sure, obviously they will still be finalizing any development issues, etc and the videos didn't have any straight specs, but it is looking very interesting as a replacement to the standard computer fan.

It smaller devices it could make a large difference if the cooling is as good as they say it is, it machines such as AIO a lot of space is normally dedicated to cooling, freeing up some of that space could allow manufacturers to sling in some higher end hardware.

I read somewhere else that they can shift quite a bit of air, but I reckon we will have to wait for some proper specs from GE - very nice concept though and it will be interesting how it develops.

DOES LIKE!!!!!!!!!!!! We need a breakthrough like this!

Interesting. I wonder how long they will last ... with flexing the metal like that very rapidly.

I'm very interested to see how this comes together as well. These could have a lot of implications for cooling in tight spaces. In a desktop, it may come down to custom/enthusiast mods of these to see them put to use, but smart phone and tablets will see a definitely benefit.
I have ideas off hand on how to put these in a desktop, but don't think any are actually viable. Then again, i'm no pro-modder as of yet thumb.gif

Shown fitted to an ultrabook in the video, so sounds legit. I love a nearly silent HD 7950 !

Most smart phones and tablets could sure run a little cooler IMO.
