Abstract
A waist-mounted evaporative personal cooling device designed to cool the back of a user, comprises a blower (25), a liquid reservoir (29), a means to deliver liquid from the reservoir a mist of droplets into blower-forced air (33) or directly onto the skin area to which the forced air will be directed (45), and a duct (27) to guide forced air under the user's shirt or blouse and directly onto or across the skin of the user's back. The device improves on prior art coolers by delivering a powerful evaporative cooling effect directly to a user's back, while being compact, comfortably wearable, and requiring the user to do little or nothing to get its benefit.
