Evaporator assembly for a vertical flow type ice making machine

A vertical flow type ice making machine, the machine comprising:

• one or more evaporator assemblies, each of the one or more evaporator assemblies comprising:
• a frame;
• a plurality of vertical cooling surfaces, each spaced at a distance and extending in a first direction within the frame;
• a plurality of horizontal cooling surfaces, each spaced at a distance and extending in a second direction perpendicular to the first direction within the frame,
• wherein, an intersection of the plurality of first and second cooling surfaces defines a plurality of ice forming blocks;
• at least one fluid flow line positioned on an upstream side of each of the one or more evaporator assemblies for supplying liquid onto the plurality of ice forming blocks;
• a plurality of shaped metallic sheets vertically stacked one above the other, each shaped metallic sheet of the plurality of shaped metallic sheets comprising
• a conductive wall extending vertically, the conductive wall including a first surface extending vertically and a second surface extending vertically, the first surface and the second surface forming opposite sides of the conductive wall,
• a horizontal cooling surface of the plurality of horizontal cooling surfaces, the horizontal cooling surface including a plurality of slots for accommodating the vertical cooling surfaces, and
• a first bend joining a vertical end of the conductive wall and a horizontal end of the horizontal cooling surface,
• wherein the first surfaces of the conductive walls are configured to accommodate the plurality of ice forming blocks and the second surfaces of the conductive walls are configured to come in contact with at least one of refrigerant and defrost fluid,
• wherein the second surface of each of the conductive walls defines a channel of a plurality of channels, and
• wherein, each of the plurality of channels are configured vertically one above the other;
• and
• at least one defrost fluid tube positioned on an upstream side of the plurality of conductive walls for selectively supplying the defrost fluid onto the plurality of conductive walls.
