A wierd place to stick a TEC..what do you think?

[train22]

Hi guys, I just had an idea that is just crazy enough to work. I thought of somehow using a peltier to cool down the water by connecting it onto the radiator fins or even build a radiator that would use that keeping the hot side facing the big fan.

So the fan cools the peltier down yet we would make better use of the air that way. Has anyone ever tried this?

are you thinking about something like a airchiller but were one heatsink is in the water?here is a link to a page with instructions for a airchiller (http://www.hardwareoc.com/airchillerz.php)
If so it has already been done(not by me though).

That might be an interesting idea, sticking one half of the air chiller in the water. it would be a whole lot easier and quiter(no delta fans on the heatsinks) and probably cheaper to just get a refrigerator unit (compressor raidiator ext) and put the cold plate in the water.

Also water can only get so cold before it freezes. i don't know if this would work, but if you got enough air chillers and a well enough sealed case to where you brought the case temperature well below freezing(water condincing on case would be weird, need lots on insalation inside the case) and thus making that air cooled setup better than a normal watercooled setup. Better yet you could spend lots of $ with about 6+ air chillers to bring the case temp below freezing then internaly watercool the setup w/ pelters for extreme homemade cooling.

in the end though, it seems like the best idea is to put the cold end of a refrigeration setup dirrectly onto the CPU...

an interesting idea, good luck if you try it.

HELLO! I just suggested that in another post on "chilling water" like 20 minutes ago! Ahhhhhh! :D

If anyone else pulls this off, tell me, I'm going to try it this or next weekend, hopefully

[Random Nonsense]

if you mean what i think u mean it will be amazingly innefficient... as the TEC will contact only the ends of the find, so little surface area

[Ridenow]

Some one tried this a while ago, I do not remember who. It blocked airflow and had very poor contact. It made things worse.

Just got myself two el-cheapo HSFs from radioshack and a nice pelt to go between them(as well as an LCD thermometer). I'll post results and pics when I get it up and running!

[BrianCapps]

what if you put a HS on the cool side of the TEC and a HSF on th ehot side, then submerge the 'cool heatsink' in the upper part of your res. (hot water rises). That way, the hot water passes through the HS blades and is cooled as it transfers its heat to the pelt. Huh?:)

[fuzzba11]

That was pretty much the plan, yes ;)

[KLowD9x]

Why dont you clamp a waterblock to the HSF w/ the TEC?

[train22]

don't forget guys, that this does cause a lot of condensatin so you can't just stick the waterblock on the cold side and a HSF on the hot side and just stick that on the cpu it will drown it.:rolleyes: What I originally suggested was some sort of a airchiller but that would be built on the Radiator.

[fuzzba11]

Yeah, my chiller will be cooling the resevoir water, though, since I'm planning on working without a radiator. I figuired it would be too dangerous to use a peltier in the usual fashion right now, because after looking at results Dan from dansdata.com got I was kinda scared. That thing fails and you have pure insulation- not fun.

I've also come up with two other ideas, build the cool side into a bong, and either have it dribble sideways down over the heatsink. Either that or just mount the bong vertically and use a showerhead.

[kevin_bouchard]

hey fuzzball
If I were you I would construct a vertical bong, and have a pelt cooled heatsink in front of the pumps intake(inside the reservoir)
The only problem with this setup is if the water freezes.
but either than that it would work great.
