CONTAINERS COOLED BY DIFFUSION EVAPORATION Russian patent published in 2007 - IPC F25D7/00 A47D13/00 F16L11/04 

FIELD: cooling equipment.

SUBSTANCE: container cooled by diffusion evaporation comprises casing having one or more walls. At least 5% of area of surface of one or more walls is occupied with matrix providing diffusion evaporation. Matrix contains porous hydrophilic material. Matrix allows small amounts of molecules of volatile vapor to pass therethrough. Vapor produced by evaporation of liquid provides cooling of container.

EFFECT: increased efficiency in cooling of beverage containers without usage of mechanical pumps.
