Does anyone see a problem with supplying air to the cool tube as shown

to make sure  cool air contacted 100 per cent of the inner surface of
the cool  tube.  If it just swirls in from the inlet, might there be
hot spots?     Jerry

You won't get any airflow unless you hook the 1-1/2 inch tube to a source
of dynamic pressure. Restricting the out let will hurt rather than help.

If you really want to cool the tube better you need internal
fins. No easy way to do that.
