Claims
- 1. A cooling device comprising
- means for permitting transfer of water vapor from a first surface;
- means for adsorbing the water vapor and transferring heat of adsorption toward a second surface; and
- means for resisting flow of the heat of adsorption toward the first surface,
- wherein the adsorbing means is a desiccant layer and the transfer permitting means is an open cell material.
- 2. The cooling device according to claim 1, wherein the adsorbing means is a molecular sieve layer.
- 3. The cooling device according to claim 1, wherein the adsorbing means is a desicaant material.
- 4. The cooling device according to claim 3, wherein the desiccant material is one of a powder and pellets.
- 5. A cooling device comprising
- means for permitting transfer of water vapor from a first surface;
- means for adsorbing the water vapor and transferring heat of adsorption toward a second surface; and
- means for resisting flow of the heat of adsorption toward the first surface,
- wherein the resisting means and the transfer permitting means are incorporated in a single layer of material.
- 6. The cooling device according to claim 5, wherein the material is an open cell foam.
- 7. The cooling device according to claim 6, wherein the adsorbing means is a desiccant layer.
- 8. A cooling device comprising means for permitting transfer of water vapor from a first surface; means for adsorbing the water vapor and transferring heat of adsorption toward a second surface; and means for resisting flow of the heat of adsorption toward the first surface, wherein the transfer permitting means includes a peelable film layer opposed to the first surface.
- 9. A cooling device comprising
- means for permitting transfer of water vapor from a first surface;
- means for adsorbing the water vapor and transferring heat of adsorption toward a second surface; and
- means for resisting flow of the heat of adsorption toward the first surface,
- wherein the adsorbing means includes a surface with an adhesive opposed to the second surface.
- 10. The cooling device according to claim 9, wherein the transfer permitting means includes a peelable film layer opposed to the first surface.
- 11. The cooling device according to claim 10, wherein the three-mentioned means are associated in at least two separate pouches.
- 12. The cooling device according to claim 11, wherein the transfer permitting means is an open cell material.
- 13. The cooling device according to claim 12, wherein the adsorbing means is a desiccant material.
- 14. The cooling device according to claim 13, wherein the first surface is a person's skin and the second surface is a material forming a sealed garment worn by a person.
