The agent 118 is adsorbed. Thereby, the refrigerant in the needle heat pipe 123 evaporates further, and cools the material 12 in the beverage can 14. After heat is transferred from the material 12 to the heat pipe, it is transferred along the heat pipe to the second portion 120 until all of the refrigerant 122 has evaporated.

FIG. 14 shows a modification of the apparatus shown in FIG. 13 that uses an absorbent rather than an adsorbent. The physical form of the absorbent can be a cloth, a membrane, a powder with a binder, a composite, an adsorbent bed, a pallet, or a bead. These absorbents may be made from simple metal foils (e.g., aluminum sheets) coated with plastic, and tissue paper, plastic foam or paper fibers and the like.

The refrigerant 22 evaporates from the adsorption means 32, moves from the outer wall 34 to the inner wall 30 as shown by the arrow A, and is absorbed by the absorbent 222. The heat generated during the absorption is transferred to the inner space 36 and evaporates the refrigerant 38 therein. The evaporating refrigerant can be released by operating the valve 40.

Referring to FIGS. 15A-D, a tubular device 10 is shown having adsorbing means 32 for refrigerant 22 and absorbent 18. At the lower end of the tubular device, fins 154 are provided to increase the transfer of heat into device 10 as indicated by arrow Q1. When the heat absorbing means 38 transfers to the device, the refrigerant evaporates, and the evaporating refrigerant is absorbed by the absorbent 18, and the heat generated at that time can be released as shown by the arrow Q3. FIG. 15B shows the device 10 in the form of a substantially rectangular plate. The plate has on one side the absorbent 18 and on the other side adsorption means 32 for the refrigerant. This configuration increases the surface area, thus increasing the evaporation of the refrigerant 22.
