Abstract
A self-contained evaporative personal cooling device has an articulated C-shaped housing that fits conformally around a user's neck or forehead. The housing retains and urges at least one heat dissipating plate conformably against the user's neck or forehead. A sponge material within the housing contacts upper and/or lower portions of the metal plates but is spaced-apart from the plate to form a plenum. In use, the sponge material is saturated with water introduced through slots in the housing. A DC powered fan within the device draws air into the housing and circulates the air within the plenum and out through exit openings in the sponge material and housing. Moisture from the sponge material wets the plenum-facing surface of the metal plates, which surface preferably has been treated with a wicking material. Fan-circulated air promotes evaporation and heat is withdrawn by the plates from the user's neck or forehead, thus cooling the user.
