Hiding the silo, but as what would you form the cooling tubes, to avoid to be recognized for what they really are?
Like bee-hive frames on the back wall of the alu-box?
With genuine wood frames around the perimeter to confuse? Vertical airflow between the “frames” of aluminium?
Or making the alubox upper part double-walled?
Weight/function “weighs” heavily on the decisions…
Now, that you have a powerful fan blowing around the silo, would it be easier to metal-glue a ~15 mm broad, 1mm thick aluminium slice with a 3 mm 90 deg. “foot” continually tight-wound on the silo?
About 100 turns for a 300 mm height.
Nothing new to hide, conciderably increased cooling capacity… just an improved “cowling” around new ribbons…
Finding the heat-resistant (two component glue)
And a “winding machine” with locking; no backwind-slip!
Returning to grate-dreams…
