Abstract
A compact evaporator unit for a household refrigerator including a partition dividing the refrigerator into two separate compartments. The partition is formed with an evaporator compartment in which the evaporator is positioned. The evaporator comprises a tubular member having an extended heat exchange surface in the form of a pair of longitudinally extending helically coiled portions. The coiled portions are arranged parallel with the rear coil being elevated relative to the front coil. The rear coil is extended to form end coils which provide a central area between the end coils to accommodate a fan employed for moving air through the evaporator compartment. The rear coil being raised so that the flow of air passing through the evaporator compartment will impact on both coils to thereby increase the frost tolerance of the evaporator.
