WTF is that? Two jellyfishes fighting?
I see your concept, but I have a question or two.
pH, do you want to equalize flow or favor the center of the TEC? That has been the argument in the past couple posts. Would favoring the center bring lower temps to the core?
Another solution would be to use the original design of a bunch of parallel lumpy channels going straight across, but stagger the inlet and outlet: like one barb on the top right, one on the bottom left.
