PROBLEM TO BE SOLVED: To provide a cooling apparatus capable of keeping cooled state of a beer barrel for longer hours in a stable manner and rationally assuring a cooling heat source.SOLUTION: This invention comprises a cover body installed at a beer barrel, a cold water circulation passage having both ends connected to a cold water source and at the same time forming a heat exchanging part with the beer barrel at the installing surface of the cover body, and a pump for supplying cold water from the cold water source to the cold water circulation passage. It is preferable that the cover body is removably installed around a barrel part of the beer barrel. Further, it is also preferable that the material wound around the barrel shows flexibility. In turn, it is preferable that the cold water circulation passage is formed by arranging the heat exchanging part in a zig-zag manner. Further, as the cold water source, a water-cooled type beer dispenser can be utilized.SELECTED DRAWING: Figure 1 |
