Technical requirements for aluminum tubes for refrigerator fin evaporators

1. Aluminum tube size: according to the design requirements, choose the appropriate aluminum tube diameter and wall thickness.
2. Aluminum pipe processing: aluminum pipe to be cut, bending, forming and welding processing, to ensure dimensional accuracy and surface finish.
3. Evaporation area of the tube body: according to the design requirements, determine the evaporation area required by the evaporator tube body.
4. Segment spacing: according to the design requirements, determine the refrigerator evaporator segment spacing, generally requires a uniform distance between segments.
5. Segment processing: Segments should ensure smooth surface, high flatness, and no air leakage at the interface with the aluminum tube.
6. Segment layout: Segments should be arranged according to the design requirements, ventilation should be uniform, and the evaporation effect should be excellent.
7. Contact rate between segments: the contact rate between segments should meet certain requirements to ensure the evaporation effect and energy transfer efficiency.
8 segment anti-corrosion: segment surface to do a good job of anti-corrosion treatment, increase service life.
9. Segment sealing: the interface between segment and aluminum pipe should be sealed to prevent gas leakage.
10. Segment cleaning: during the production process, segments and aluminum tubes should be cleaned regularly to ensure the evaporation effect and health safety.
