Claims (8)

In a beverage supply apparatus that includes a cooling water tank for storing cooling water for cooling beverage ingredients flowing through an immersed cooling coil, and a cold storage for cooling a stored BIB, and that supplies beverages ,
One surface of the cooling water tank side wall and the one surface of the cool box side wall facing the one side of the cooling water tank side wall are configured by a panel having a heat exchange function, and the heat is absorbed from the air in the cool box and is radiated to the cooling water. A beverage supply device characterized by the above.   The heat insulation means having a heat exchange function is further provided on the cold storage side of the panel, and the heat exchange means absorbs heat from the air in the cold storage and dissipates heat to the cooling water. The beverage supply apparatus according to 1.   3. The beverage supply device according to claim 1, wherein the panel and the heat exchanging means are made of a metal material and absorb heat from the air in the cold storage to dissipate heat to the cooling water.   4. The heat exchange means according to claim 2, wherein a fin is formed on the cold storage side, and the fin absorbs heat from the air in the cold storage and dissipates heat to the cooling water. 5. Beverage supply device.   5. The beverage supply device according to claim 4, wherein the heat exchanging unit is configured such that the fins are arranged in a lateral direction, and the fins absorb heat from the air in the cool box and dissipate heat to the cooling water.   The beverage supply according to claim 4 or 5, wherein the fin is provided below the water surface of the cooling water, and the fin absorbs heat from the air in the cold storage and dissipates heat to the cooling water. apparatus.   The heat exchanging means is provided with convection imparting means for imparting convection from the lower side of the fin toward the upper side of the fin. The convection imparting means allows the air in the cool box to be moved from the lower side of the fin. The beverage supply apparatus according to any one of claims 4 to 6, wherein heat is absorbed from the air in the cool box by applying convection upward.   The convection imparting means has a fan that is rotated by a drive motor, and absorbs heat from the air in the cool box by imparting convection from the bottom to the top of the fin by rotating the fan. The beverage supply apparatus according to claim 7, wherein:
