Peltier cooled water reservoir

[Fanman]

I had an interesting idea a couple months ago, and thought I should ask all you knowledgable folk before I try it.

I want to peltier (quad 80 watt) cool my water reservoir on my water cooler. I figure (although it will raise case temps a lot), that it will be a lot safer and much more effective than directly pelting a T-bird.

The plan is to cut 4 holes in the side of my plastic junction box resevoir of slightly smaller size than each pelt. Then I attach each pelt on the outside of the resevoir with thermal epoxy and a good solid coat of thermal silicone around the edge of that. Pelts will be attached to HSFs by clamping one to another with a very thin coat of JB weld in between (a long proven method of permanent strong thermally conductive attachment).

The other option is to put them all on one copper plate with many
pieces of smaller diameter copper pipe countersunk & soldered into it that sit in the water. That assembly would sit on top of the resevoir.

As long as I put a large HSF on each Peltier and put it in front of my 120MM sunon intake, it <i>should</i> work fine. I'm not expecting too much, but who knows... could not work at all, or could work great.

Any input on attachment or the whole theory would be appreciated.

Thanks,

I have had the same thought! A radiator-less H2O setup would be sweet! Check this link, all you would have to do is install this sucker in the Res. I just don't know if it would get cold enough or if it would get TOO cold!

I've seen somthing somewhere on this, can't remeber but i think they used an old heatsink and placed the pelter cold side on the H/S and a fan on the hot side.. place the H/S in the reservior/ this cools the water...

paint the only thing needed to design a good comp part

Woah, you can't cool a peltier with just a fan, you need a BIG heatsink on the hotside. Hell my watercooling struggles to keep the hotside of my TEC cool.
Personally I don't think you'll get this working well, what's the big deal with having a radiator, they're cheap, easy, and effective, peltiers are hard, and don't work well.
As for that iceprobe, if it draws less than 50W I don't think that too cold is going to be an issue, more like your water will be steaming in the container.
