TEC Coolant Chilling Device - plz add your oppinions! - Page 4

post #31 of 46
All attempts at cooling with mineral oil as far as I've seen run fairly hot and I'm sure there's a reason for it. What's the thermal resistance of the oil? What's the viscosity?

Either way I'd move away from using TEC's and rather run a couple of phase change coolers if attempting something of this caliber considering how much liquid you have to cool. Or if you had a sealed computer case, hooked up multiple inlets on the front and outlets on the back and mounted a pump that circulates the oil; then mount air cooled tec's along the path I think you might actually be able to pull it off as you establish a directional flow of the oil.

A submerged radiator on the other hand is just a chiller with insane amounts of surface coverage; for some reason I'm convinced that the heat exchange provided by this would be absurd considering how efficiently radiators transfer heat under ambient temperatures. The heat exchange is bound to be much greater when every surface the water touches has a 50c+ temperature difference and unlike oil the temperature of salt water will equalize quickly.

Using a flat copper water block as a chiller just doesn't seem as efficient; isn't this why they started designing all these crazy patterns on water blocks?

EDIT: Just found this document - ftp://ftp.hartscientific.com/msds/minoil.pdf
According to Hart Scientific mineral oil has an operating temperature of 10c - 175c so you definately wouldn't be able to get remotely close to sub zero cooling.

Double edit: This (ftp://ftp.hartscientific.com/msds/dynalene.pdf) on the other hand has some real nice properties; it's made specifically for heat transfer, has a higher electrical resistance compared to mineral oil and an operating temperature down to -65c; the only downside is that it'll ignite at 60c

LOL...nice find. Didnt know that the freezing point was sooo low, on the oil...there must be a suitable alternate. That Dynalene sounds pretty interesting, too expensive though..lol.

So, to run a 'submerged phase' you would need something electrically inert, such as mineral oil, but with a much lower temp range......hmmmmm. Liquid based petroleum? I will look deeper into this.

*rep for the post.

Theres some fluoro 3M fluid stuff thats meant to be pretty good. Pricey stuff though.

Some Aussie did it with that fluoro 3M fluid. It was like $100-200 per bottle or something. Didn't improve performance that much though. The main source of heat are still the CPU and GPU. Cooling everything else doesn't really help.

I've always wanted one like this http://www.xtremesystems.org/forums/...ad.php?t=96080
Thats a sick setup for sure....Q though,

*Wouldnt a TEC setup produce similar temps? Was the purpose of that chiller, so he didnt have to insulate?

wouldn't that mean though that the water isn't picking up much heat?

I think I'll start a thread dedicated to general information about comercial chillers but I've been looking into buying some sort of purpose built peltier based air conditioner to set on top of my intakes to cool the radiators while at the same time cooling the voltage regulator and memory on my video card as it's located directly beneath my rads (blowing air onto the card and pulling out underneath).

I found this awesome website (http://www.thermoelectric.com/2005/cat/index.htm) and just wanted to share it with you all. I know one of my colleagues bought some stuff from them so I'll see if I can't try it out and post some info.

another interesting website is http://www.chillercity.com/home.html

http://www.lauda.de/ is also pretty cool but way too expensive for my blood.

Each molecule of water is not changing very much in temp, but the flow is so fast that it removes a lot of heat.

Im beggining to think that its pointless having a RAD in the loop the TEC is cooling, coz once you get the water below ambient, the rad will actually be heating the water rather than cooling it...
