Ian,
I would think a set of louvered holes at the input for the blower air
in the chassis would do it. That is if they were aimed in different
directions from one to the other. This would make the incoming air
streams sort of bounce against each other making it turbulent I would
think.
Sadly, it doesn't work that way. All that can possibly give you is a few
gentle swirls in the smoothly flowing air.
The transformer gets hot because it is insulated by a stagnant layer of
warm air on the surface. To create enough turbulence to scrub that layer
off, you have to put in some extra mechanical energy - in other words,
use a fan.
