swamp cooler drawings
 

does anyone have plans /drawings for a working swamp cooler all i can find are nonfunctioning replicas look cool but pointless

Check YOUTUBE for 'home made automotive swamp coolers'
The very best any could do is lower the temp. by 3 deg. below outside ambient temp. and introduce excess humidity to the interior.
(probably just as pointless as a replica.)

I rigged up a cooler using a 12v bilge pump, some dryer vent hose and an air intake intercooler inside an ice chest. The contents of the ice chest separated from the air flowing through the inter cooler. I put the intake hose on the floor and the cool output up high, hooked onto the package tray behind the seat. You could even use dry ice but would have to vent the C02 out somehow to avoid build up in the confined space.
The hardest part was finding an intercooler to fit a commercial ice chest cooler, I suppose you could build a cooler box to fit a suitable sized intercooler. I got the intercooler, and bilge pump ,assorted 4" stainless couplings and rubber hose connectors off eBay, and the ice chest from mallwart. I've got a tad more than $100 in the whole rig. It gets hot in GA too, and it's way too humid here for a swamp cooler to work at all.

They work best in a very dry climate, where the increase in humidity actually helps.
