Hello hello,

I'm trying to design a water block which will be sandwiched between the cold sides of two peltiers (Think Swiftech MCW-CHILL). I've alread dealt with all of the heat distribution issues using pelts entails, now I'm trying to design the actual block to be sandwiched between them. I was thinking of using a crosshatched-channel design similar to the Swiftech's, but for what I'm doing I really don't care about flow rate (I need 0.3 GPM at the very most). I just need to chill a tiny bit of water moving relative slowly as quickly as I possibly can. Specifically, if I can drop ambient water coming in by 10 degrees C as it comes out, I'll be a very happy man.

So far, what I've thought of doing is:
-Make the water block bigger than the peltier surface to maximize the time the water is in contact with cold metal and maximize the internal surface area of the water block
-Install swirl inserts in the feed pipe to maximize turbulent flow
-Mill the block itself down so that it is as thin as possible (shortening the time it takes for the entire block to cool and minimizing energy wasted cooling copper)

I'm at a bit of a loss as to how to go about this, as what I want to do seems like the exact opposite of what most people are going for in their water block designs.

Can anyone help?
