ABSTRACT:
An ice cube making evaporator design comprising an aluminum roll-bond evaporator plate (50) which is encased in a plastic grid (59) of vertical and horizontal ridges, thereby forming an array of freezing sites (28) on both sides of the plate. Integral refrigerant passes (52) in the evaporator plate may be designed to be flat on one side, enabling the freezing sites (28) to be in direct contact with the refrigerant passes (52). Adjacent refrigerant passes (52) are flat on opposite sides of the evaporator plate (50') thereby enabling significant improvements in heat transfer geometry and performance. Boundary layer interrupters (68) and conductive anchors (86) are also disclosed for the purpose of heat transfer enhancement.
