Technical Properties Main Material Aluminum tube, aluminum foil. Structure Type Aluminum tube through fins, being expanded (the fins is one piece structure). Heat Exchange Mode and Features Refrigerant→Evaporator→Fins The finned evaporator has air cooled type and free frost type, can reach -18℃ of freeze temperature and -2~4℃ of cold storage temperature; The condenser can dissipate the heat caused by evaporator. Surface Preparation Anodic Oxidation: aluminum tube, aluminum fins. Internal Condition No leakage, can meet internal cleanliness requirements of CFC and free CFC refrigerant. Other It is freezing type mostly, without limitation to model and size. Properties: 　It can adopt aluminum tube and aluminum fins, or copper tube and aluminum fins, through expand tube. It has small volume, large refrigerating capacity, and uniform refrigeration, without frost. It is especially applicable for adjusting distribution of cooling capacity in each cold chamber of multi-doors refrigerator. Application Scope： 　The finned evaporator applies to different types of single-door, double-doors, and multi-doors free-frost refrigerators. It also can be used as evaporator or condenser of other refrigeration equipments
