Made this 12CM fan shroud to increase efficiency (in silly, uneducated theory) and at the very least, to help locate-to-center the wet/soaking media tower in my DIY 5-gallon-bucket swamp cooler. I have no idea whether it increases effectiveness of the evaporative cooler due to aerodynamics, since A. I don't know squat about aerodynamics and B. I haven't bothered to do any A/B testing. But it definitely helps keep the cooling tower properly located within the bucket and centered under the fan, so 100% of the air from the fan passes through the cooling media rather than blowing to the outside of the tower and straight out the exhaust vents.
Who knows, someone might find it useful. If you're making a DIY swamp cooler from a 12CM fan and a 5 gallon bucket, well, certainly I recommend it. :-)
BTW, the 12CM, 12V "Delta" fan you see in these photos is a CRAZY, CRAZY 12V fan. Highly recommended if airflow and static pressure are all that matter, and noise is a non-issue. Holy cow, I've never seen a fan so small move so much air.
