How to connect the aluminum corrugation to the projector for exhaust/cooling?

Question

Projectors

Good afternoon,
I am installing a home theater projector in a closed cabinet and I want to provide it with hot air from the lamp through the aluminum corrugation. The question arose how to connect (glue, nail, etc.) this corrugation with a diameter of 100 mm to the projector, if the projector case looks like a remnant (Epson 6600w)? I would like the fastening of the corrugation to be reliable and over time not come unstuck from the temperature and, if possible, removable for prophylaxis. On the other side of the corrugation, a forced exhaust fan will be installed.
I will be glad to any advice. Thanks,
Dmitry

Answer 1

I am considering the option of creating a casing around the body made of tin with a rubber window seal around the perimeter so that the air does not go outside. Allows you to place the hood from anywhere in the casing, which can be convenient when there is a lack of space at the projector's outlet grill (for example, it is located close to the muzzle, which almost abuts against the wall)

Answer 2

If there is a cuff on the corrugation and a steel case, magnets rule.
