Interesting idea. I though it was going to be more like the 'cooling glove' [1] which actually cools you down, rather than just making you think you're cooler. Hairless skin on the hands and face has blood vessels close to the surface, and cooling those parts is proposed to quickly cool your blood and core temperature. It looks like the energy and space requirements for such cooling glove are too large to make it portable, however, and it also doesn't work much better than simply holding an ice pack! So, for portable devices, it seems like at most we can only trick ourselves into thinking we're cool.
