Sealed alcohol cooling pad

If you put alcohol on your skin it cools it as the alcohol evaporates. Cooling your skin is just what you want if you have a fever. But obviously that would keep using alcohol, and putting alcohol directly on your skin isn't good for it. So perhaps you could put the alcohol in some kind of pad such that it evaporates where the it is near the skin and condenses elsewhere, thus disappating the heat.
