In the application of air conditioning and refrigeration industry, compared with ordinary smooth tubes, the heat transfer surface area of spiral tubes is more than 1.5-2.0, which greatly improves the refrigerant flow mode and strengthens the boiling and condensation heat transfer effect in the tube.
In the application of heat exchange equipment, the steel pipe or stainless steel pipe is rolled by machine tool, and the scale on the surface of the spiral tube is spiral.
