Evaporator structure for refrigerator-freezer

摘要

An evaporator structure comprises a heating tube and a refrigerant tube. The heating tube contains a heating wire, and at least the refrigerant tube contains heat exchange fins. The tubes and fins are of one-piece extruded construction. The evaporator structure is bent to form straight sections interconnected by curved sections. Along the curved sections the tubes are spaced apart to define air-conducting paths. The fins may alternatively be formed in a plate which interconnects the tubes.
