Abstract: An evaporator for refrigeration devices comprises a serpentine tube bundle having a plurality of spaced-apart parallel fins. The tube bundle is arranged to provide sets of tubes in a staggered arrangement to increase the number of tube passes for the height of the evaporator and space the tubes apart to improve efficiency of air flow patterns over the tubes to enhance heat transfer. The fins are made of ultra-thin material of a thickness less than 0.20 millimeters. The fins have an embossed pattern to reinforce the fins through which the tubes extend in appropriately shaped apertures. Due to the thinness of the fins, portions of the fin walls are displaced by inserting the tubes in the apertures to ensure metal to metal contact between the fin and the tubes. The embossed pattern is such to induce turbulence in the air flowing over the fins and tubes to considerably increase the efficiency of the evaporator unit.

Abstract: In a refrigerator cabinet having a rolled-form, three-sided wrapper to form the cabinet sides and top, a front liner, a rear panel having a compressor compartment shell, a molded plastic base for interconnecting the wrapper sides, front liner and rear panel with compressor compartment shell. The base has a support portion molded therein to support a compressor within the compressor compartment. The cabinet can be readily assembled where considerable economies in manufacture are realized.
