1. A beverage dispenser, comprising:
- a lower housing, the housing having front, rear, right and left vertical side walls extending upward to a top horizontal end wall from a bottom horizontal end surface for defining a cold plate retaining interior area,a cold plate held within the cold plate retaining interior area and the cold plate having front, rear, right and left ends, and the cold plate positioned within the housing interior are along the bottom end surface thereof wherein the cold plate front, rear, right and left ends are positioned adjacent the housing front, rear, right and left vertical end walls respectively, the cold plate having a top surface and having one or more beverage lines extending through an interior thereof below the cold plate top surface, the one or more beverage lines each having an inlet end extending from the cold plate for connection to a source of beverage and each one or more beverage line having an outlet end for connecting to a beverage dispensing valve so that ice retained on the cold plate top surface provides for heat exchange cooling of a beverage as it passes through its respective beverage line through the cold plate from the source thereof to a beverage dispensing valve, and the one or more lines passing through the cold plate in a direction from the front end to the rear end thereof in a serpentine fashion wherein the one or more lines alternate back and forth between the cold plate right and left ends so that a high heat exchange portion of each of the one or more lines lies substantially within and defines a high heat exchange front portion of the cold plate and where the high heat exchange cold plate portion lies substantially directly below an access opening in the housing top horizontal end wall.

Abstract
A beverage dispenser of the cold plate type as shown wherein the cold plate is oriented within a housing of a dispenser such that the fluid lines extending through the cold plate extend in a pattern for preventing ice bridging occurring at the back end of the device. The cold plate also includes stainless steel wire coils within each water line along an end portion thereof for turbulating the water as it passes there through to provide for enhanced heat exchange between the fluid and the cold plate and the fluid line end portion.

1. A beverage dispenser, comprising:
-
a lower housing, the housing having front, rear, right and left vertical side walls extending upward to a top horizontal end wall from a bottom horizontal end surface for defining a cold plate retaining interior area, a cold plate held within the cold plate retaining interior area and the cold plate having front, rear, right and left ends, and the cold plate positioned within the housing interior are along the bottom end surface thereof wherein the cold plate front, rear, right and left ends are positioned adjacent the housing front, rear, right and left vertical end walls respectively, the cold plate having a top surface and having one or more beverage lines extending through an interior thereof below the cold plate top surface, the one or more beverage lines each having an inlet end extending from the cold plate for connection to a source of beverage and each one or more beverage line having an outlet end for connecting to a beverage dispensing valve so that ice retained on the cold plate top surface provides for heat exchange cooling of a beverage as it passes through its respective beverage line through the cold plate from the source thereof to a beverage dispensing valve, and the one or more lines passing through the cold plate in a direction from the front end to the rear end thereof in a serpentine fashion wherein the one or more lines alternate back and forth between the cold plate right and left ends so that a high heat exchange portion of each of the one or more lines lies substantially within and defines a high heat exchange front portion of the cold plate and where the high heat exchange cold plate portion lies substantially directly below an access opening in the housing top horizontal end wall. - View Dependent Claims (2, 3, 4, 5)
