Abstract
A self cooling can has water on a pre-wetted wick ( ), in a chamber and an adsorbent in another chamber communicable upon actuation of the can with the chamber. One or both of the chambers is at low pressure. Upon actuation the pressure of the wick drops, water vapour is absorbed by the adsorbent from the internal atmosphere and more water evaporates from the wick to replace it, thereby causing a cooling effect in heat generated in the adsorbent may be contained by but a take-up system, such as phase change material or microcapsules of high heat capacity material such as water.
