Cray SV2 Technology Overview Greetings, I ran across this link from Cray Supercomputers which shows a 30 minute video of the SV2. Of importance is the manner in which they cool their chips. Should make for some interesting food for thought. Thanks and regards... Joe |

More food for thought. Might incorporate these into video cards cooling. Sorry upfront for the links, just sharing ideas. |

Compressed air spinning at 1 million RPM is going to be a tad noisy for ur average computer
![]() not to mention the hot air jet from the other end at 240 degrees F ![]()

Yes sir, i agree it would be a challenge to come up with ways to utilize the heat side of the vortex tube to some useful function. My guess would be to keep your coffee hot. On the first post, the Cray video starts to talk of the cooling system at about 10 minutes run time, but to be honest, the whole video actually gave me wood.

OMG. I can't wait to see someone coming up with this kind of device on his PC. Think of it, it would spit out flames. Wow. I must have one...

the spray deal is cool, but totally impractical for our uses.
They are using a Liquid to Vapor multiphase system that took TONS of engineering work. Also the pumps you would need to move that kind of pressure would cost 800 - 1000$ at the least. Its a cool idea, but a cooling system like that for a PC would run in the range of 2000 - 3000$ total in the end. I will just buy a faster CPU for 200$ and be done with it instead ![]() EDIT: About Votex tubes. Another great idea... but where you going to keep a steady compressed air source? a big air compressor with a 100% duty rating?? Thats a few thousand bucks there alone. What about the TERRIBLE screaching noise those tubes make. They are NOT silent, they are louder and more annoying than anything I have heard in a PC ( I have seen them used at a local metals shop to cool a lathe bit). Both are awesome ideas, just not practical for our use.

Yeah I agree, It was pretty stupid to post those links. I thought that this might be the right forum for it... you know liquid or phase change cooling...some folks have never seen phase change cooling in action, so I thought it might be useful. Sometimes we underestimate the caliber of folks we have in here, and it is just a matter of time before someone builds it...
thanks and regards... joe

Not stupid at all, it was VERY interesting, and is food for thought. THANKS!

I found this article in a Swedish Techpaper.
It is basicly a refrigerator without a compressor. http://www.nyteknik.se/pub/pub27_3.asp?art_id=19074 Look at the picture and i will try to explain how it works. The round disk, CD-size, has thermally isolated sectors. In each sector there is a insert of Gadolinium. Gadolinium is a metallic element that is magnetocalorific. Which means it heats up when it's put into a magnetic field. When a sector goes into the magnetic field it heats up. The heat is transferred away to a radiator. When the sector exits the magnetic field it cools down to a temperature below ambient. When this "cold" sector reaches the "thing" that is supposed to be chilled it takes the heat from the "thing" and gets warmer. The "thing" has now cooled down a bit and the, now warm, sector continues to the magnet to dump this heat. And so the cycle continues. The positive side of this construction is that the only energy needed is to rotate the disc.

That sounds pretty awesome. Is there a name for this device? I am going to try to translate the url tonight to find out more about it. Hopefully systrans works on it. I had a friend working on a similar setup for use as an energy generating device, but I didnt know the details. Thanks for sharing that.
