ABSTRACT:
A heat exchanger for fluids is disclosed in the form of a cold plate of the type utilized with ice cooled beverage dispensers. The cold plate has a heat conducting casting in which are embedded conduits for various liquids to be cooled, such as various flavored syrups, sweet water and carbonated water. One of the fluid conduits, such as that for the carbonated water, is formed of two tubular members, with a third tubular member interconnecting the first two tubular members. The first two tubular members are substantially planar with a convoluted or serpentine shape. The two tubular members are positioned as two layers, with the top layer or first tubular member adjacent to the top surface of the casting against which the ice is positioned. Carbonated water or other fluid is introduced into the bottom layer, or second tubular member, and after the carbonated water has passed through this member it is conveyed to the end of the first tubular member adjacent the end of the second tubular member into which the carbonated water was initially introduced. After passing through the first tubular member, the cooled carbonated water is removed for dispensing.
