ABSTRACT:
A spine fin refrigerator evaporator is formed of lower and upper sections of elongated straight runs, which have fins thereon and have their ends connected to each other by return bent ends. The lower section is formed with two rows of the elongated straight runs in an A shape to provide a passage therebetween through which air initially flows through the evaporator so that frost can be gathered without blocking air flow therethrough. The upper section has three rows of the elongated straight runs with the fins of adjacent rows overlapping each other to provide an efficient heat transfer from the refrigerant in the elongated straight runs to the air whereby the lower and upper sections combine to provide a practical and efficient evaporator. If desired, the upper and lower sections can be vertically spaced from each other to have a defrost heater disposed therebetween.
