When the material starts to dry and the cooling effect starts to drop, you just pull on the cord that is hanging into the car (from the vent) and it spins the mesh tube which causes it to refesh the material with new water from the tank. So evaporation of the water cools the air flowing through the unit. The open end of the cooler (pointed to the front) introduces air into the center of the mesh tube and in turn the air flows through the wet material towards the exit point in the cooler, The exit is the vent that rests inside the cars window. You pour water into the tank and the material soaks up some of the water. Around that you have a blanket or gauze type material. The concept for a swamp cooler is that inside the unit you have a horizontal tube that is made of a mesh wire like chicken wire or rabit fence wire. These swamp coolers were first made in the 30s, and finally petered out in the late 60s or so, although one can still buy new ones for that typical overdone look, with every available and conceivable accessory that so many restored old cars sport.
