Identified: Art Bell's "UFO" Aluminum Louvered Sheets - Heat Exchanger Fins

Vent vs radiator.jpg

"Arts Parts" refers to a collection of objects that were supposedly anonymously sent to Art Bell.

The "vent" material is very interesting:

That's a much more specific look. Very similar to air-conditioning vents, but on a dollhouse scale.

UPDATE Dec 12 2019 - The following is a summary of the identification from the thread below.

It's almost 100% certain this is a sheet of louvered fins for a heat exchanger (like a radiator or air conditioner).

Here's a VERY good match.

Note the exact same pattern of alternating direction blocks of 10 louvers, with long vertical grooves between the louvers where they are bent into an S-shape.

Here's another example showing the alternating directions of the louver pitches.

And another, showing the normal zigzag structure of the fins, with some fins partially flattened.

Well done @deirdre, who first found this connection.

someone’s tenacity finally pays off
I was just trying to cover up the holes in my dollhouse floor.

but what cracks me up, is that TTSA built this fancy expensive company with a lot of bigwig guys who are going to reverse engineer alien space flight technology, and they don't even know what a car radiator looks like. :)

me thinks they have a rather big learning curve to overcome.

I think this speaks to the importance of crowdsourcing. As I wrote here:
https://skepticalinquirer.org/newsletter/curated_crowdsourcing_in_ufo_investigations/

 
the thickness was 0.157 mm (average of 3 measurements) on the edge (i.e. not over slits). The thickness over the slits was 0.304 mm
is this a typo? is it possible the vent height is only .3 mm? would we be able to see .3mm? I ask because the "How it's made" video says the sheet the louvres are made of is only 1.5mm thick. so i'm wondering if art made a typo, or am I. 1 and a half mm is written as 1.5mm right?

Yes you can see 0.3mm, for reference aluminium foil is generally between 0.015mm and 0.024mm thick.

1.5mm seems a bit on the thick side for radiators, that's about as thick as most of the coins in my pocket. 0.15mm to 0.3mm would probably be the right sort of ballpark for the louvred metal sheets.
 
1.5 mm sound right for a structural supporting strip, or a tube, but the louvered fin itself is going to be more like 0.15mm. You can probably see the end of similar fins on the outside of your AC.
