Abstract
Abstract An ice chest for a cold plate or drop-in type beverage dispenser wherein the cold plate includes a carbonator integral therewith and the ice chest also includes an aluminum casting as a side wall of the ice bin with prechill cooling coils embedded therein for prechilling the water before it is fed to the carbonator. The cold plate includes a semi-cylindrical sleeve extending downwardly therefrom and forming part of a carbonator housing. The sleeve is in intimate heat exchange contact with both the cold plate and the carbonator for cooling the carbonator.
