Abstract: A self-contained evaporative personal cooling device fits conformally around a user's neck or other body portion. The device includes at least one heat dissipating member that is urged conformably against the body portion to absorb heat therefrom. The device-facing side of this member preferably has a large surface area with a liquid-wickable surface. A liquid-retainable material contacts at least a portion of the wickable surface area and also defines at least one air plenum. Ambient air is moved along the plenum, preferably by a battery-powered fan. The air transfers heat from the member, cooling the user, and is exhausted from the device. A thermostat can sense temperature at the heat dissipating member to control duty cycle of the fan to prevent overcooling the user.
