Vegetable oil as a coolant

[welshtom]

HI, i recently tried this experiment :-

Any suggestions on how to cool the oil cheaply?
Any suggestions on anything really .

phase change chiller!! where abouts are you? i'm in aberystwyth and have a chiller that would be perfect for the task.. could get together and do some old school p3 overclocking if your not too far away..

Please post the results... this is very.... interesting... hehe

I’ve heard some not so good stuff about the oil cooling. I know of the things they stated was that the oil ends up growing algae or bacteria due to it setting so long. I’ve always wanted to try it... but never got around to doing submergible cooling. Some guys have tried oil on the hard forums... check out their threads its pretty interesting. Project think tank is one of the best over there.

bblack tub would kill the algae prob, but bacteria i dunno lol

[Bloody_Sorcerer]

you'd need something oil soluble, since we're dealing with vegetable oil (water insoluble), not water.

[drcrawn]

oil won't grow algae or bacteria- EVER! even food quality oils

three things that bacteria or other microbes hate:

Fat
sugar
salt

Not sure how oil would cool better than water though...although you could probably do some fun stuff with a low viscosity oil and some sub zero temps...

its winter soon so you can easily stick that outside at like -30C and dont have to worry about condensation.

[Gimmpy224]

-30 in canada, dosnt get below 30 here lol

but ive lived in -60 before

[WeStSiDePLaYa]

is 99% alcohol lighter than oil? if so you could pour isopropyl alcohol in there and it would form a barrier over the oil. would prevent things from getting in it, with the lid on it shouldnt evapourate too quickly.

We are trying to get baby oil now as that wotn smell/rot so much.

unfortunatly we need £25 to achieve this.

We have bought new parts to go in the baby oil pc. a dual slot 1

We just donations now.

Up to £5.69 via paypal so far.

Come on guys wheres ya sense of adventure.

paypal to thaxley@hotmail.com

name will be printed on website and you will be my hero

hey tom, where abouts in wales are you? i have some old hardware (slot 1 CPU's and the like) and as i said before i have a chiller that could chill the oil problem being it would thiken up aswell..

Im in swansea .

dealing with gallons of oil wouldnt be fun.

The oil has too much flow resistance, won't work too well, i've seen other guys doing this before

[Banzai]

I want to see the out come of this. Looks interesting.

Into a watercooling system maybe. But as they do in the project he linked why not.

Two things :
-AFAIK Oil become conductive when exposed to air
-@ which temp oil freeze?

If it don't freeze to high you can then cool you entire system with a chill

As vegetable oils cool, wax crystals form, and the oil goes cloudy. The crystals can form a film on filters, blocking the flow of fuel. The temperature at which this occurs varies widely according to the oil type, from well below freezing point to well above freezing point.

It even varies for the same type of oil: new food-grade rapeseed or canola oil is usually "winterized" so that it doesn't cloud in the fridge and put people off. It will work nicely down to -10ºC, but once it emerges from the fryer, partly hydrogenated, degraded and probably containing some tallow from the food fried in it, it will only stay liquid and not plug filters down to freezing point or just above.

So it seems that the freezing temperature really depends on the oil.... and it also seems that it doesn't really freeze, it just thickens and some of the components in the oil form crystals.
