Default Evap Question

I've seen a lot on the web about evap cooling of air, and evap cooling of liquid, and they all seem to be saying the same thing.

I know a bong tower will cool the water as the energetic water molecules evaporate, leaving less energy in the water.

I know a swamp cooler will blow air cooled to at best the wet bulb temperature.

The same mechanism of evaporation is used in both cases, are both the air and water cooled in both cases? In the swamp cooler, is the water is being cooled by the evaporation, and then the greater specific heat of the liquid water compared to the combination of air and water vapor results in a entropy temperature closer to that of the liquid water?

I am just trying to wrap my mind around what's happenning, and unfortunately I have no access to a swamp cooler so I can't just let it run and then check the water temperature, and I don't have a bong tower to check the exit air temperature to verify my hypothesis, and all the links I've been through so far for evaporative cooling haven't been much help.

Anyone got any good links or insights?
