1. An evaporator for freezing water into ice cubes, the evaporator being chilled by cold refrigerant from a refrigeration system, the evaporator comprising:

  • a first plate;

    a second plate mated with the first plate, the second plate having a stamped sepentine depression, displaced oppositely from the first plate, with traversing spaced-apart parallel sections connected by bend sections so as to form a continuous channel for carrying chilled refrigerant defined between the first plate and the depression of the second plate;

    an array of icing sites on which water is frozen, each icing site disposed on an outside surface portion of the parallel sections of the depression of the second plate, over the refrigerant channel to allow for efficient transfer of heat from water flowing across the icing sites to chilled refrigerant in the channel; and

    means for impeding formation of ice bridges including inserts of material with relatively less of a heat transfer rate than the icing sites located on the outside surface of the second plate between the parallel sections of the depression, the insulating material spacing apart vertically adjacent icing sites in the array of icing sites.
