Definitions

  • EP 1 223 400 B1 It is proposed to produce at the groove bottom between the ribs undercut secondary grooves which extend continuously along the primary groove.
  • the cross section of these secondary grooves can remain constant or varied at regular intervals.
  • the invention includes a metallic heat exchanger tube having integrally ribbed, ribbed and ribbed ribs formed on the tube exterior, the rib stem projecting substantially radially from the tube wall and a channel formed between the ribs in which spaced apart additional structures are disposed.
  • the additional structures divide the channel between the ribs into segments.
  • the additional structures locally reduce the flow-through cross-sectional area in the channel between two ribs by at least 60% and at least limit a fluid flow in the channel during operation.
  • the combination of the segments according to the invention with a channel which is closed except for pores or slots gives a structure which has a very high efficiency in the evaporation of liquids over a very wide range of operating conditions.
  • the heat transfer coefficient of the structure reaches a consistently high level.
  • the first additional structures may be outwardly projecting radially outward protrusions from the channel bottom.
  • the exchange of liquid and steam is determined locally.
  • the segmentation of the channel over the groove base is particularly favorable for the evaporation process, since the excess temperature is greatest at the bottom of the groove and therefore there is the highest driving temperature difference for the bubble formation available.
