I have never seen those in the wild. Maybe the purpose is to exhaust the hot air into ducts and then take it away? Otherwise I cannot think of a reason to use them.
If you are making a lot of these, its not too expensive for a custom die. But if 40x40mm works thats quite a standard size so you should find something that works.https://www.aliexpress.com/i/32821793383.htmlhttps://www.aliexpress.com/i/32780223588.htmlhttps://www.aliexpress.com/i/32904858135.htmlhttps://www.aliexpress.com/item/1-piece-4CM-fan-radiator-Aluminum-profile-cooling-tunnel-40-40mm-Length-can-be-customized-free/32913499568.html
