Abstract: Heat exchange apparatuses configured for various applications so as to transfer heat to or from a fluid to be heated or cooled, respectively. The heat exchange apparatus includes at least one fluid line for containing the product fluid to be heated or cooled. The line includes an inlet into which the fluid is introduced, as well as an outlet at an opposite end of the line through which the fluid exits. The heat exchange apparatus also advantageously includes a cast metallic body which encases at least a portion of the fluid tube.

The coolant system has inlet and outlet manifolds and a plurality of coolant lines each including a plurality of loops. The fluid system includes at least one fluid line preferably also including a plurality of loops, and preferably is interleaved with the coolant lines. The metallic unit incorporates the coolant and fluid systems. An apparatus for cooling at least one fluid includes a cold plate and a dispenser unit. The cold plate unit includes a coil basket having a fluid system and a coolant system. The fluid system includes a plurality of fluid lines each comprising a plurality of loops. The coolant system includes coolant inlet and outlet lines, at least one inlet manifold, at least one outlet manifold and a plurality of coolant line segments each comprising a plurality of loops.

Abstract: An apparatus for low volume dispensing of soft drinks preferably uses no mechanical refrigeration equipment, depending instead on heat transfer from a bin of ice to cool water and soft-drink syrup for beverages. A heat-exchange plate desirably includes transfer lines for incoming water to and from a carbonator. A portion of the heat exchange plate, or a second heat exchange plate, includes transfer lines for syrup and for carbonated water. The carbonated water is used to cool the syrup through the second heat exchange plate, and is also mixed with the syrup to dispense a soft drink. Heat from the incoming water and syrup is removed by melting ice in the ice bin, which may be replenished as needed.

Abstract: An apparatus for cooling at least one fluid includes separable cold plate and dispenser units. The cold plate unit includes a coolant system, a fluid system and a metallic unit. The coolant system defines a cold plate portion and a tower portion. The cold plate portion of the coolant system has a primary inlet manifold and a primary outlet manifold, and the tower portion has a secondary inlet manifold and a secondary outlet manifold. The coolant system further includes a first plurality of coolant line segments connecting the primary and secondary inlet manifolds and a second plurality of coolant line segments connecting the secondary and primary outlet manifolds. The fluid system also defines a cold plate portion and a tower portion, the portions being in heat exchange relationship with the coolant system. The metallic unit includes unitary cold plate and tower portions which respectively incorporate the cold plate and tower portions of the coolant system and fluid system.
