If you were to make one, you could use alternating sized coils - one or two large circumference coils followed by one or two as tight as you could make them. That would likely break the water flow up enough to be effective.

The one I've seen in person works really well - it has the inlet tube on the opposite edge from the outlet tube (i.e., if you lay it on its side with the inlet tube on the bottom left, the outlet tube would be on the top right), so the water probably gets agitated a bit before exiting.

I was looking at commercial CFC systems for HVAC sysetms. What they do for this type of chiller is insert a smaller diameter pipe in the middle of the coils to keep the water flow against the coils and preventing temperature gradients. I don't know if they fill the central pipe with something to keep if from "floating' against the coils or if they fill and brace it but just about anything would be better than a big open area where water can flow through without chilling the coils.

of course I can't find it now. If I find the links I'll post them.
