Integral Finned Serpentines

Integral Finned Serpentines (Extruded Tubes)

Broşür

For this type of serpentines, fins are created with direct tube by using extrusion method. It provides the best heat transfer, because there is no resistance between tube and fin. Integral finned tubes are classified as follows:
» Integral finned serpentines with single tube
» Integral finned serpentines with double tube
» Corrugated and integral finned tubes
» Turbofin tubes

Integral Finned Serpentines With Single Tube:
They are produced by using soft tubes of materials such as copper and aluminum with below sizes:
Tube Diameter (D) : D 15-25mm (before extrusion)
Fin Height (L) : L 2-5 mm
Fin Thickness (t) : t 0.20-0.40 mm
Pitch (h) : h 1.33-3.20 mm

Integral Finned Serpentines With Double Tube:
Best heat transfer surface area is obtained by using integral finned serpentines. But this method could not be directly applied with hard materials such as carbon steel, stainless, bafon and brass. To apply extrusion method for these types of tube, a soft tube such as copper or aluminum is placed on them and fin is formed with that outer tube with below sizes:
Inner Tube Diameter (D1) : 10-33.70 mm
Fin Height (L) : 5-15 mm
Fin Thickness (t) : 0.20-0.40 mm
Pitch (h) : 2-3.20 mm
