Definitions

  • the invention relates to an exchanger tube for a heat exchanger according to the features in the preamble of the claim 1.
  • the troughs running through the ribs also run at an angle deviating from 90 ° to the pipe longitudinal axis.
  • the flanks of the troughs are convex.
  • the transitions from the flanks on the flat bottoms of the troughs and on the flat head sides of the rib areas between two neighboring hollows of a rib are sharp-edged educated.
  • the depth of the troughs is smaller than the radial one Dimension of the ribs. All troughs are of the same depth educated. In the production of the troughs, this becomes the Deformed material ribs in the front of the troughs Channels deformed into it.
  • the production of the known exchanger tube takes place in preferably in that first in a rolling process the structure of the later inner surface on one side a metal band, then the metal band a slotted tube with an internal surface structure is formed and then the slot edges are welded become.
  • the invention is based on the prior art Task, an exchanger tube with an inner To create surface structure, with which a clearly more intensive flow through the channels can be guaranteed can and take advantage of an equally good Evaporation or condensation performance with reduced Connect rib weight.
  • the embodiment of claim 2 provides that on the one hand all primary ribs and on the other hand all secondary ribs each have the same radial extent. This means, all primary ribs have the same height as well all secondary ribs have the same height.
