Coffee can teach you Physics. If you like it hot, you need to keep it compact, as close to spherical as you can, so the heat doesn't radiate away, and the liquid evaporate.
So getting it to cool is even easier. Just spread it out. You can do this by pouring it from one container to another in a thin trickle. Now that's skinny! And it cools rapidly.
But that's not cold. If you want it cold, you should put it in a tall, thin, closed container in a cold place. An empty water bottle, ready for the recycle bin, would be perfect.
Keeping the lid on the bottle would prevent the coffee from evaporating. Just put it in a cold place, and get it when you're ready.
Note that the "cold place" doesn't have to be your refrigerator. It could be just a cold bath of water, perhaps with an ice-cube tray emptied into it. Especially if you're going to transfer the drink to another container before enjoying it.
My mother, bless her hillbilly soul, would offer me a cup of coffee and add, “It’s been saucered and blowed, Honey!”
Yep, I know the cooling tricks to some extent!
