Not saying it works, but it is in the ballpark. An idle human dissipates something like 100 watts. Heat and humidity interfere with your mammalian superpowers and you start having trouble getting rid of your 100 watts. A device which moves a faction of 100 watts can get you out of the horrible parts of the mammal powers (sweating buckets).

To compare to CPU cooling, a human is a small CPU in terms of power production. Peltier CPU coolers are not popular because they tend to be less efficient than big air heat exchangers… but… A Peltier CPU cooler is an "instead of" device. A Peltier cooler bolted on to your fanny is an "in addition to" cooling device.

Um actually: only humans & horses use perspiration for cooling (https://en.wikipedia.org/wiki/Perspiration)

That article is misleading. Cats and dogs have far fewer sweat glands, and they're mostly concentrated at the bottom of their paws, so it's not their primary method of thermal regulation, but they will sweat when they get hot to aid in cooling down.

You will pant to cool down in extreme cases too.

But the article is correct. It's not remotely a primary dissipation method for most mammals. Those animals don't need to sweat to stay alive.
