Cooling "Lungs" Outperform Traditional Fans

Cooling "Lungs" Outperform Traditional Fans

Boffins have developed an efficient air-cooling system based on the human lung.

Heat is the latest, and perhaps most daunting, technological hurdle facing the consumer electronics market, particularly when it comes to mobile computing. Upgrading a smartphone processor is pointless if the end product erupts into flames half-way through a session of Angry Birds. Current heat-distribution methods - heat sinks, fans, liquid cooling, etc - perform adequately on current-scale PCs, but they're struggling to keep up with the shrinking scale of mobile tech. Researchers at General Electronics have come up with an interesting alternative; A solid-state cooling system based on the human lung.

The prototype cooler involves two 40mm by 40mm thin metal plates bonded to strips of piezoelectric ceramic. These ceramics, dubbed Dual Piezoelectric Cooling Jets, flex when an AC current is applied, causing the whole cooler to continuously push a 1mm-wide jet of air in and out of itself. It may look kind of creepy, like a fish gasping for air, but the prototype cooler is smaller, quieter and nearly two times more energy efficient than a traditional fan. The frequency of the unit's "breaths" can also be adjusted on the fly - you can add your own "heavy breathing" joke.

Of course, computer components don't operate in a vacuum, as any PC enthusiast who has ever gazed into their parent's ancient Dell with a look of abject horror on their face can tell you. Run a PC long enough and its insides begin to resemble that of a dust-flavoured candy floss machine. To test the cooler, GE blasted it with fine grain dust from multiple angles. The cooler was still running perfectly four days later. Apparently, the air velocity of the jets keeps the unit clean.

While this tech could come in very handy in the notebook market, GE is leaving the real-world applications to another company; It's licensed the system to Japanese thermal solutions outfit, Fujikura.

Could use a set of those for this toshiba.

hahahahahah!!!!

This is hilarious because I recently became a "PC enthusiast" a couple years ago and as I was looking to build my first computer I took a look into my parents ancient Dell and had the exact reaction/thought/description you just gave.

Grey Carter, you are officially amazing.

Hmm, my next massive upgrade will be water cooling rather than air =\ otherwise, sounds interesting, my current HS has a bit of dust on the fins XD

My next comp is running a liquid cooling system, if there is proof that this new system is better I'll give it a look. Still, I like the energy efficiency thing, having laptops run longer wouldn't go amiss, and the adjust on the fly thing interests me very much. if it is twice as energy efficient, then adjusting it to twice the strength can only mean good things! *insert mad doctor face here*

I thoroughly disagree.

Glad someone picked up on that one.

It's a passing fad it'll blow over.
This entire story makes me sigh.
It's just a bunch of scientists venting their minds.
The investors are just full of hot air.
I doubt the public will ever get wind of this.
The only people that'll get this are air heads.
Yeah okay I'm done.

First of all, they failed at biology. Lungs don't breathe.

Secondly, they must have some serious suction power for the small volume/movement to be even more effective than fans. More work from star trek.

i dont see how in and out is more efficient than constant stream of air. unless the breathing is so fast even a hamster cant compete. efficient design is much better than efficient cooling. same cooler, same CPU, HP turns on 90 C Asus on 30C. all because o different venting design.

Good fan beats everything else in the long run. and no, please dont be my fan.

Am I the only person who kept getting thrown by the guy wearing safety glasses for the interview off putting?

Today, they learn how to breathe.
Tomorrow, they'll learn how to overthrow humanity.

Do you mean that its the diaghram that breathes while the lungs hold the air and exchange gases, or is there some deeper, more abstract side of respiration that they kept secret from us in our biology classes?

The lungs do not control the breath, the lungs are merely the physical representation of the transfer of essence from the world into the body. The breath is the life.

On GON they quoted it as being in the hundreds of Hz, and I can't think of any creatures off the top of my head that breathe that fast.

It'd be interesting to see this used in gaming consoles at the majority of xbox 360 space is the drive and the heatsinks (like, 2/3 of the cases space give or take) which could be significantly reduced to resemble the later PS2s.

Also would be good if they were more efficient than fans as I doubt these would get dusty on the same scale as fans do considering their surface is always vibrating as opposed to fans that have copper parts for cooling purposes.

And you thought your boss was breathing down your neck through your mobile phone already...

mind= blown.

that will be great for personal armours, since you sweat like a pig in them...

Yeah, the tech's cool.

Did anybody else find it really amusing how everyone was wearing safety goggles for the entire video, though? I can imagine a marketing guy going "Okay, how do we emphasize that our engineers mean business? Let's make them wear protective glasses FOR THE ENTIRE VIDEO!"

What I learned from that video was that, they still make laptops with the tit-mice, I thought they stopped being a thing like in the mid 2000's or something.

I see what ya did there :P

Seriously though, I do wonder if this would be as efficient on a large scale, such as for PC's. This could be one hell of a cool upgrade for custom rigs :)

Tell me about it. I once opened up an old PC where the dust was quite literally caked in there to the point where you could dig it out with a spoon.

OT: This sounds like quite an interesting bit of technology. Would like to find out how well it holds up in real world applications.

Still occasionally find clit mice on ultracompacts but mostly on the more business oriented laptops. Most of the Thinkpad lines still have them along with Dell Precisions and some of the HP Elitebooks.

Trackpads might be a bit easier to use but they're less precise pointing devices.

What, now we gotta make the jokes for you? What are we not paying you for?

Expect to see this on the next iPhone. It'll solve the overheating problems (Smartphones get STUPIDLY hot when you are using them to make and receive calls! Even my Nokia 6120C gets uncomfortably hot during phone use. And it isn't even a smartphone!)
