- dougvfr750, on 06/20/2008, -1/+22So does this mean that my laptop will now keep my beer cold?

- jwhite22, on 06/21/2008, -2/+13No hot air expelled? Have you ever felt the heat expelled under or behind your refrigerator or air conditioner?
There is heat and a lot of it expelled. The removal may be more efficient (More heat removed per watt of power used) but it will belch out heat. - Vaeduus, on 06/21/2008, -0/+8no...in the back of a refridgerator there are fins to cool the freon or whatever proprietary fluid is going through the loop. All of the heat from the processor still has to go somewhere, namely your lap or out the back.
- sockpuppets, on 06/21/2008, -1/+6They're not real men, they're reading the manual!
- lacreme, on 06/21/2008, -0/+5phase cooling has been in custom desktops for a while, but it often requires an external unit.
- DirtPile, on 06/21/2008, -1/+6There goes battery life.
- total1337ness, on 06/21/2008, -1/+6Wouldnt the problem with this be that a refrigerator sometimes causes water in the air to condense. If that happens then the processor would short circuit.
- Vaeduus, on 06/21/2008, -0/+4read up on phase change cooling for desktop pcs. you have to insulate all around the processor socket and in some cases use heaters because it cools the chip so much. check out the vapochill series here:

Water vapor would indeed condense and short the processor if it got cold enough...Some phase change systems get really ***** cold. - inactive, on 06/21/2008, -0/+3That's such an impractical idea.
I'd rather just soak my PC in mineral oil to keep cool, Aquarium style
http://www.pugetsystems.com/submerged.php - krnldmp, on 06/21/2008, -0/+3Yuh, and requires more energy input.
- guyincognito, on 06/21/2008, -0/+2that processor is still going to get hot
- daviddiaz, on 06/21/2008, -0/+2I would hate the noise involved. otherwise, it seems cool.
- HappyScrappy, on 06/21/2008, -0/+2I did that. Doesn't really work.
You can also use soybean oil, although your machine will become rancid eventually. - alexforcefive, on 06/21/2008, -0/+2Read the article, then make the comment. Or not, in your case, since it was completely unrelated
- Ratteler, on 06/21/2008, -0/+2Can they also make a pair of boxers to keep my jewels cool in summer?
- rugabug, on 06/21/2008, -0/+2Anyone at Purdue know where exactly the pic was taken. It looks like the Aero lab at the airport but I'm not sure.
- 1randomnumber, on 06/21/2008, -0/+2I got a quick tour of this thing a few months ago, early spring semester. It's actually in Herrick Labs, the kind of crappy run down lab over by Lilly and the ag buildings. It's across from farmhouse.
And on a side note, woo professor Groll! - Gman1223, on 06/21/2008, -1/+2It would be quite odd to have a refrigeration system built into a computer device, what if the refrigerant leaks out? Then you're left without cooling, and it would probably cost quite a bit to have it repaired. Where will the condenser sit? And what about the moisture left from the evaporator? Won't that have to be channeled somewhere? This article doesn't go into very many details about how this system will work. How much will that little compressor take to power?
This idea seems like it would work much better on a standard desktop than it would on a laptop. This has already been done on large scales with gaming rigs. - SpaceDreamer, on 06/21/2008, -1/+2there's no way that this can be more efficient than heatsinks and fans.
Computers components don't need to be refrigerated because the ambient air is already cooler than the components. So they just need ventilation.
If you add a refrigerating system, you'll have to ventilate it too anyway, because the heat has to go somewhere.
So you'd just be adding some useless noisy clumsy power-leeching thing between the components and the ventilation. - XternalHD, on 06/21/2008, -1/+2Sarcasm?
- Ledjar, on 06/21/2008, -2/+3They've had these cooling systems for a wile, i remember seeing one you could buy for 600 bucks back in 2004 and it would uber cool your processor, unfortunately it was half the size of a mid tower.
- known, on 06/21/2008, -0/+1SpeedFan
http://www.almico.com/sfdownload.php - HappyScrappy, on 06/21/2008, -0/+1Honestly, I expect phase-change (as they call it, vapor-compression) cooling will be used to cool cars before it makes its way to computers.
Even Formula 1 cars currently still just use water radiators to cool. - XternalHD, on 06/21/2008, -0/+1Whats liquid cooling?
- Pfkninenines, on 06/21/2008, -0/+1http://www.engadget.com/2007/05/21/usb-mini-fridge ...
When it doesn't come built in, slap in a new USB device. - gcnaddict, on 06/21/2008, -0/+1A comment with no value whatsoever combined with an out-of-context link?
You *****.. - HappyScrappy, on 06/21/2008, -0/+1Don't try telling that to these guys:
http://www.xtremesystems.com/
Some of them use liquid nitrogen cooling systems so they can reach world record overclocks. - krait, on 06/21/2008, -0/+1"I want one! It's the first day of summer!", says dude with hot potato on his lap.
- Hello1024, on 06/21/2008, -0/+1This is the first comment I've seen from someone who understands the issues.
The only time you need refrigeration is when you want to keep the components at or below ambient - for example this system could be used to cool electronic sensors inside furnaces, engines, or other places where everything is too hot for the components to work.
One possible last use is if you want to save the minimal amount of energy used to power the fan of current systems, but that would likely use a passive cooling system, since with a heat pump you've got to power the compressor and a fan for the radiator. - edmcguirk, on 06/23/2008, -0/+1Formula 1 cars have to dump massive amounts of heat out of their radiators. I doubt an AC system could pump that much heat.
AC technology would have to give significant aerodynamic advantages through smaller and hotter condensers and also the whole AC system would have to be as light or lighter and as small or smaller than the radiator system currently in use.
If you could design an AC system that could dump heat through a tiny white hot heat sink, weigh less than 2 gallons of water plus a radiator and water pump, and draw less power than a water pump, you could name your price. - EJTower, on 06/21/2008, -1/+2Oh man you showed him Lance.
- inactive, on 06/21/2008, -0/+1 So if your laptop gets 2 and half hours battery time how much does it get when you add a mini refrigeration unit to it? And what about the heat the refrigerator removes, plus the heat it is generating by it's own operation. In a the closed system of a laptop you'd be adding heat by using refrigeration, even though you'd be cooling the chip.
- edmcguirk, on 06/23/2008, -0/+1No. it is perfectly legitimate to use heat pump technology to transfer heat at above ambient temperature.
Let's imagine you want to lock the chips down to 10 degrees above ambient temperature. Normally you would need fans to move a lot of air across a heat sink because you can't transfer a lot of heat when the difference is only 10 degrees. If you use a heat pump instead, the chips can be regulated at 10 degrees above ambient while the heat pump's condenser is running at 30 or more degrees above ambient. At that temperature differential, you would not need a fan because radiative heat dissipation would be enough.
The condenser could be smaller than a conventional heat sink because it is hotter and it could be located some place on the laptop where extra heat is not so uncomfortable. - l800LEMMINGS, on 06/21/2008, -0/+1it would be interesting if they could use a greener method of magnetic cooling without the magnets disrupting the electronics
http://www.physorg.com/news107183785.html - Sponky, on 06/21/2008, -0/+1Heat transfer, rather than phase change cooling as in this case.
- Metalcastr, on 06/21/2008, -1/+1You can actually build a refrigerated PC yourself, or buy a case that has a compressor built in. Great for overclocking.
http://gomeler.com/2006/04/16/vapor-phase-change-c ...
Also has a nice write up on how refrigeration works. - PathDaemon, on 06/21/2008, -1/+1Wow. That's an asston of thermocouples they've got there...
- icewolf, on 06/21/2008, -0/+0I guess they are doing this so the laptop will be able to survive a nuclear blast?
- reddikilowatt, on 06/21/2008, -1/+1Up next: A washing machine for your TV!
- krnldmp, on 06/21/2008, -1/+1Well that's pretty stupid. There's no reason to chill a processor below the ambient dew point unless you're in an extremely humid area or just want to short out your computer.
- inactive, on 06/21/2008, -1/+0The company I work for is also currently working on a new cooling method for CPUs, except it's more "integrated" into the CPU chip itself which would mean some of the most efficient cooling yet (more than this method from the looks of it)
Hopefully we'll be seeing it in the market in the coming years! - suckaPU, on 06/21/2008, -2/+1BTFU
- chrgrose, on 06/21/2008, -2/+1One of the obvious problems is condensation. Would kind of suck if the refrigerator is working too well and, if it isn't isolated from the atmosphere, you'll get a short quicker than you can say ***** THING SUCKS.
- Spyder228, on 06/21/2008, -1/+0Yeah these have been around for years now.
- accvrat, on 06/21/2008, -4/+3Pshhh, another just around the corner thing we never hear about again, or see on the shelf...
Post it when i can buy it... - MarkusX, on 06/20/2008, -6/+4Doesn't that cooling system help the whole system to be more energy efficient?
After all there is no energy (heat / hot air) expelled. -
