A few issues
1) Why does anyone mix copper and aluminium? Isn't this just asking for trouble? You may be able to reduce the corrosion with an inhibiter, but copper/brass plumbing can last centuries. It is also pretty easy to solder/braze copper to brass.
2) The top plates look a little massive.Can you cut the size and make the whole thing a little lighhter? Solder/braze an elbow to a thinner plate and you are done with less metal (lower heat capacity.
3) What is the metal for the lower plate. I assume that is it copper (is it oxygen-free high conductivity)
4) Overall, I like the idea of making the water move through channels, but I wonder if having a couple channels in parallel rather than a single long chanel. This would increase the flow rate.
