Abstract, Disclosed is a self-contained rapid cooling device, that retains heat produced from the cooling process and 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 phase separator prevents unvaporized liquid from passing into the second chamber. The device is self-contained because a material in contact with the sorbent removes the heat from the sorbent to prevent the reduction in the cooling effect produced by the first chamber.
