Abstract
Disclosed is a self-contained, rapid cooling device that can be stored for indefinite periods without losing its cooling potential. A liquid in a first chamber undergoes a change of phase into vapor which cools the first chamber. A sorbent in a second chamber is in fluid communication with the vapor and removes the vapor from the first chamber. A heat sink material thermally coupled to the sorbent collects and irreversibly captures heat transferred from the vapor to the sorbent.
