Thread: DIY 12 v swamp cooler?

Tweet

Like Mike says, the pads have to stay wet, and as the water evaporates mineral deposits are left behind to plug the media unless the flow rate is kept high with a steady blowdown stream to carry them away. Some of the simple ones for houses used a water hose on top, trickling water down through the pad, and excess flow going to the ground - also called Evaporative Coolers for the process employed. All you needed was an old furnace fan to blow air through the pad, into the house. You can probably get away with no fan, just duct air through it using vehicle speed (veolcity pressure), but on a vehicle you're going to have to have a pump and reservoir (or a veeeeeeery long hose ). Deposits are going to be a problem unless you use distilled water which is going to be expensive! In an arid climate you're going to use a lot of water. Mold can also be a problem if the pad stays wet with no air flow. Google "evaporative cooler parts" and you'll get lots of information.

Then you already know the problems associated with minerals, mold, deposits and water flow. Good luck with your project.

Maybe like this? Ok, I'll go away now.
