     What is wrong with these cooling system
designs?

Paul,
 If the question wasn't rhetorical, there is no
diffuser prior to the face of the heat exchanger.
The turbulent entry and "dead" corners will reduce
the effectiveness of the heat exchanger. Better
would be to angle the heat exchanger and use the
wedge style feed with a diffuser tapered to meet the
intake.

You also get a B Bill :)  To be fair there is some
subtle factor that just
recently crystal clear to me again. Hint it affects
air cooled engines as well.

Good point Robert. Constant torque hose clamps and silicon rubber hose
should be used.
Still not what I had in mind.

OK Paul, I'll take a shot at it...

A good cooling design must have a good route for the expanding heated air to
get away from the exchanger.

Absolutely true but that is still not the major problem here.
