Definitions

  • the invention relates to a finned tube according to the preamble of claim 1.
  • Finned tubes with the specified range of pitch t R of 1.60 to 3.90 mm (6.5 to 16 fins / inch) are known.
  • Finned tubes of this type with a fin height h R of about 10 mm are used in particular in air-cooled heat exchangers.
  • the use of these finned tubes in corrosive, erosive and contaminated media, such as occur in the chemical and petrochemical sector, is already ruled out because the grooves between the fins would easily be filled with deposits and the performance of the finned tube as a heat transfer element would be significantly impaired .
  • the invention is therefore based on the object of specifying a finned tube which retains good heat transfer properties even when used in corrosive, erosive and contaminated media.
  • the object is achieved by the three characterizing features a) to c) of claim 1.
  • the rib cross-sectional area A R is measured in the longitudinal direction of the tube). This on the one hand proposes an open rib structure that counteracts contamination of the grooves between the ribs, and on the other hand provides a relatively solid rib that is resistant to the attacks of the corrovive and erosive media.
  • the rib height h R is preferably in the range 0.8 mm ⁇ h R ⁇ 1.7 mm, in particular in the range 1.0 mm ⁇ h R ⁇ 1.5 mm.
  • the values for the surface ratio of the ribbed outer surface A0 / smooth outer surface A 0, smooth as a function of the fin pitch t R lie between the values of the equations.
  • the smooth tube has an outer diameter which corresponds to the fin diameter of the finned tube.
  • the fins taper towards the tip of the fin.
  • a rib width B> 0.3 mm at the tip of the rib is preferred.
  • the finned tube For use in shell-and-tube heat exchangers, it is recommended that the finned tube have smooth ends, the diameter of which corresponds approximately to the fin diameter.
  • Fig. 3 shows a finned tube 1 with integral fins 2, which run helically on the outside of the tube.
  • the finned tubes 1 are produced in a manner known per se by the finned tube rolling method (cf. for example US Pat. No. 3,327,512).
  • the ribs 2 taper towards the tip of the rib, the bottom of the groove between the ribs 2 is rounded.
  • the rib tube sizes are explained: rib pitch t R (distance from rib center to rib center), rib height h R , rib cross-sectional area A R (hatched in Fig.
  • the finned tube 1 has a smooth end 1 ⁇ , the diameter of which corresponds to the fin diameter d R.
  • condensation performance of the condenser equipped with finned tubes according to the invention was at least a factor of 2 higher than the condensation performance of the condenser provided with standard finned tubes.
