Now, let me know if it's already been done, but I was thinking that an easy way to build a TEC chiller would be to buy a small metal container to use as a reservoir and use AS Alumina epoxy to attach a couple cheap pin-based heatsinks on the inside and outside of the reservoir, facing away from each other but in the same position on the reservoir wall. With a TEC in between the outer heatsink and the reservoir wall and some fans attached to the heatsinks outside the reservoir you could effectively pull heat out of the water to sub ambient levels. You wouldn't want overly powerful TECs because of potential frost, but I figure this might work due to increased surface area to transfer the heat more efficiently. And it'd be cheap and easy. I figure it would take no more than an hour to build and about $60 to buy the TECs and cheap heatsinks and barbs for the tubing.
