Low finned tubes are usually machined to form fins of a certain height, a certain distance and a certain thickness on the outer surface of the tubes. Finned tubes are mostly used as heat exchange elements in condensers and evaporators of air conditioners, and low finned tubes are often used in condensers. It consists of light tube and & ldquo; attachment & rdquo; fins on which the structural parameters are mainly fin tube diameter, outer diameter, fin tube wall thickness, fin pitch, fin thickness and fin height.

The practical application proves that the low finned tube also has excellent anti-fouling performance, because the fouling often forms parallel scales along the edge of the wave crest. During operation, with the change of temperature, the tube will expand and contract. This kind of "accordion" expansion and contraction will prevent fouling.
