If air bubbles are collected at the blue side, this would produce
rather large errors in thermal coupling:

This is a very good point. If the cross section is correct, there is
a pocket that can collect air bubbles. The heat exchanger was
probably filled with air at startup, and the orientation shown in the
cross section is correct I think. An air pocket should collect there
at startup.
I believe, there are so many possibilities for more or less
important errors with this arrangement, that even a precise
simulation or calculation cannot give a conclusive result.
Only improvement of the experiment and repetition can clear this
situation.

Yes, if it can ever be clear.
