It is definitely a good design.
It's a shame that the channels had to be so wide. I'm sure it would have been interesting to test this with tighter fins.
Optionally, one could braze very thin strips of copper, in that design.
There is an ideal fin spacing and thickness, as well as height. It's calculable, but it's not obvious.
Good work.
BTW, (I asked in another thread), did you consider running the test from side to side while plugging the middle barb? I believe that the middle barb, if it wasn't completely plugged, could alter the results. If you could replace the middle barb with a plug, that would be ideal.
