I've used spot coolers in data centers when experiencing HVAC issues, and we would duct the exhaust air up through the ceiling tiles. Unless you do something similar with yours, you're just whizzing in the wind, so to speak.

I've also tried one of those swamp cooler fans, the ones in which you add water and it pumps it past a wick like a real swamp cooler. It didn't work for squat. I ended up getting a real window mount A/C unit and cutting a hole in my wall.
