Zero Gravity Water Boiling

not necessarily
ammonia cooling of a space station would be considered extreme :p
;)
 
carbon carbon is a good insulator for that application because its basically a daimond matrix, has a super heat conductivity (able to even out hotspots) and is extremely tough stuff

so "insulator" doesnt necessarilly mean what you think it does in this case
its just one of several insulators
there are many artifical diamond coatings employed in extreme cooling solutions
and of course Im sure you have heard of carbon nanotubes.

The real trick is the conductive interface, a chunk of space shuttle tile aint goin to address that very well unfortunately, but check that link above ;)

howdy Papa-Ming :D
 
actually fluorinert spray cooling is available for the desktop
just a few links
19" & 23" SprayCool Rackmount Enclosures (and workstations)
Micromachined Spray Cooling (NASA)
Spray Cool Technology PDF
Magnetic Drive Gear Pumps
Spray Cool FAQs


its an area of active research for me
they even have spray cooled "waterblocks" for lack of a better word
the trick with all this is actually dealing with fluorinert which will leak through a seal that would withstand 10 atmospheres of pressure if it was water, the proper selection of the flourinert type for the phase change, the proper selecction of the pump, and they aint cheap pumps, the proper selection of the atomizers\nozzles which impact the phase change

think of it as a hybrid water cooled phase change rig
its both simpler in operation, but far far tougher to determine the right component selection
Right now I know of no overclocker employing it, and have yet to determine the lowest possible temperature it could reasonably be used for
(again that would depend on a number of factors)
but Im very interested in it

few more

now wouldnt it be hilarious if you could cobble one together with a few print cartridges :p
 
heh, very cool.

I like watching water boil at room temperature in an approximate vaccuum more tho :D
and then half the people in the class are like "is that hot?" :rolleyes:

i love physics labs!

Watching liquids boil in low gravity is an out-of-this-world experience.
It has plenty of entertainment value,
but it's teaching scientists some important physics lessons, too.

see links ;)

water can phase change too :p

Liquids ? :

Free software downloads from NASA including semiconductor devices: :cool:

Could be soon?

:D
 
hmmm Im nit subscribed to this thread
just my evil twin :p

so I missed that linkage

but I do have another to add

again in the spraycooling field

"Rather than wetting computer chips with a cone-shaped shower of coolant as do existing devices, the new system drenches chips with high velocity lines of liquid, much like sheets of wind-driven rain."
 
Lets see if I've got this right, it should look roughly like this: (totaly not made in paint!)



So, thats basicly a self contained bong cooler :p
A good one might get well below ambiant temps :eek:

instead of transfer of latent heat through evaporation (bong cooler)
think vaporization of a refrigerant instead, you can get flourinert with a boiling point of 30ºC
whereas the boiling point of water is 100ºC, so your flash vaporizing on the core itself (in some instances, inside a block in others)
