I've got a whole 'nother set of ideas I want to experiment with at home airspirit that much more closely fits your 2-loop setup. Thats essentially a water-chiller setup. I've seen a lot of the dual-loop pelt-chiller setups - this is different and new. If you want a water-chiller setup you're better off running phase-change to cool the water (as in #rotors dehumidifiers).
I know pelts create their own heat, as well as moving heat from side A to side B. I also know that pelts run more efficiently at lower voltages (create less of their own heat) while moving less heat from A to B. The theory in my above picture is to increase the efficiency of both the rad and the block (and I'm sure that it would), and if I'm right, that efficiency increase will be enough to offset the heat that the pelt creates in making them more efficient.
