Oil?

Has any one ever constructed an oil colling machine? I was thinkin about this today, since oil can hold more heat then water why not use that? Not sure if it would work though due to that it is thicker.
 
Dont know about oil but I think alcohol would be better - I am going to try it in 2008 :)
 
Where have you seen that oil can hold more energy than water?

A light oil can hold around 2Kj/Kg K

Whereas water can hold about 4.2 Kj/KG K

Alcohol can also hold about half the heat of water, but you can easily chill it down to very low temperatures... so...
 
oil is much thicker. You'd probably need a super pump with huge tubes for it to work. You would also need super filtered oil.

I don't know if the heat dissipation is the same with oil... maybe it "keeps" heat more than water. My chemistry classes are so far away!

There was someone that put his whole system in oil. That was interesting. You should google that.
 
If you try something like this remember to cut slits in the fans to reduce resistance. Since I can't think of a good way to put it I'll say it like this. Think of a celing fan, you turn it on and then hold on to it not letting it move. Since the motor is trying to spin but theres to much resistance (the oil or in this case your hand on the ceiling fan) the fan has a chance of breaking. You wont need the fans to cool anything anyhow seeing as its all submerged.

On a lighter note, I've heard that unlike youd probably think theese type of cooling solutions arent too hard to handle. They dont get too dirty, or stink, and you only have to change the water once or twice a year from what I've heard.
 
if you are talking about car oil, then i wouldnt say it would work very well, it is used to lubricate parts under extreme heat, not cool them.

If you are talking about mineral oil i believe a couple people have done submerged systems and if i remember correctly, oil did not have a major heat dissapating factor.
 
This is a terrible idea.

Without a bunch of surface area, or some sort of chiller/heat exchanger to remove the heat from the oil... The heat will continue to build up and up, without being able to escape.

Scroll half way down that page. They said the oil alone is a great setup for periods of load less than 12 hours. For running longer they added a radiator to remove the heat from the oil just like Arcygenical said. Hmm...

Reading comprehension buddy, not once did I say it was a good idea or debate Arcygenical's conclusion about it's long-term stability. Common sense backups Arcygenical's statements....


this is a great setup for periods of load less than 12 hours long. As long as you give it some cool down time, it runs some great temperatures. We do want to stress that at no time was the system unstable, ever....which was surprising! It doesn't seem too much a stretch to expect that you wouldn't put a typical computer under load for more than 12 hours...after all, even gamers have to sleep! With that taken into account, this setup as it is could serve as a great, eye catching way to cooling your computer.
 
what about synthetic oil? its alot thinned and is supposed to disburse more heat than reg oil?

I guess I just took it as somewhat contradictary to tell him not to cry before posting a link backing up what he said in the long run. A simple misunderstanding it seems.

And thats why Alcohol is best for water cooling! Of course, mixing it with lets say... mineral oil ? Something non-conducticve (as if Alcohol isnt lol) But at least it works better than water.

Alcohol is best for water CHILLING... but for regular water cooling, water is still your best bet ;). Either that or Gallium... But good luck with that one :D.

Actually, the heat would convect away from the sources in convection currents
