Building A Refrigerator For Your Laptop

[Guest]

West Lafayette (IN) - Researchers from Purdue University claim they are getting closer to develop a much more efficient cooling system that the traditional heatsink-fan design used in many computers today.

Which is easier? Make cooler processors or complicated cooling solutions that could fail?

How about developing a more effective heatpipe design. Sure it won't get below ambient but I don't need my processor to run below 25°C.

sounds cool. what if it breaks? thats got to cost a lot.

What about all the moisture build up?

Also if this leaks, there goes your system.

And why thermo-electric coolers (TECs) are not used today? They are small enough... Because it takes more power and thus reduces battery life - that's why. I think it will be similar problem with this compressors. Believe it or not, air cooling is very efficient way to cool, it just can not cool to temperatures lower then environment. But as long as your processors can work around 50C, there should be no problems...

I think you guys may be failing to see the point here. Phase-change cooling is the best cooling available period. If some scientist can figure out a way to get this bulky, typically 40 pound or more cooling system into my laptop then by all means cram that crap in there and give me the latest NVidia 10,000X reality synthesizing chip powered by a hydrogen-fusion mini reactor so I can play the latest games. OK, we'll ignore the fact that a NVidia 10,000X reality chip or hydrogen-fusion mini reactor DO NOT exist,but if they did, they would need ridiculous cooling capabilities as offered by this mobile phase change cooling solution, so leave these scientists alone and let them do their work!!!!

So long as there is no overclocking involved conventional heatsink/fan cooling should be fine for 98% of computer owners. As to the comparison of TEC and compressors power usage, there is none. A 6000btu window air conditioner uses about 500w to cool a 200sq ft room down to 61F.

A TECs used in the poorly designed heatsinks that cost $150 suck up about 200w and barely perform on par with normal heat pipe coolers.

But then again my TEC cooler which uses copper heatsinks and fans to cool the hot side and acts as an air conditioner keeps my 125w dual core cpu at 10c under 100% load.

Even with overclocking a conventional heatsink/fan is fine for 98%. The point of most overclockers is to get something for (almost) nothing, to get the most value out of a low to midrange chip and paying a lot more for exotic cooling is contrary to that goal.

Price really is the bottom line. "Best" doesn't have to mean cools the most, it can mean cheapest. Besides, think about the fact that nobody wants their devices to use so much power->heat that a different cooling tech is needed.

Oh yeah, they ignore the other crucial factor. They're only moving heat away from the source but not out of the system yet, even with this you still have to have either a large passive radiator or a fan on a smaller one. They'd increase the complexity and cost of the system, with it no more likely to outlive a simple fan on a hunk of metal since it would still most likely use a fan as a large passive 'sink adds more to the cost.

Might be more useful in aerospace applications with extreme conditions, otherwise just shrinking down an AC isn't terribly advanced.

i read that update or information first and found that is better for me as the part of <a href="http://www.appliancerepairdmv.com">Alexandria auto body</a> like Suresh Garimella and Eckhard Groll say they can miniaturize traditional refrigerator designs to become small enough to fit in desktop computers or even notebooks.
