Definitions

  • the invention relates to metallic heat exchanger tubes structured on both sides, in particular finned tubes, according to the preamble of claim 1.
  • Heat transfer occurs in many areas of refrigeration and air conditioning technology as well as in Process and energy technology.
  • tubular heat exchangers are frequently used. Flows in many applications a liquid on the inside of the tube, depending on the direction of the Heat flow is cooled or heated. The heat is on the outside of the pipe existing medium is released or withdrawn from it. It's state the technology that in tube bundle heat exchangers instead of smooth tubes on both sides structured pipes are used. This will heat up intensified on the inside of the pipe and on the outside of the pipe.
  • the transferred heat flow density is increased and the heat exchanger can be made more compact. Alternatively, the heat flow density can be maintained and the driving temperature difference be lowered, thereby making energy transfer more efficient is possible.
  • Have structured heat exchanger tubes for shell-and-tube heat exchangers usually at least one structured area and smooth end pieces and possibly smooth intermediate pieces. Limit the smooth end or intermediate pieces the structured areas. So that the tube can be easily inserted into the tube bundle heat exchanger can be installed, the outer diameter of the structured Areas should not be larger than the outer diameter of the smooth end and intermediate pieces.
  • Integrally rolled finned tubes are often used as structured heat exchanger tubes used.
  • Under integrally rolled finned tubes are finned tubes understood, in which the ribs made of the wall material of a smooth tube were formed.
  • Finned tubes have a ring or screw shape on the outside circumferential ribs. In many cases they have one on the inside of the pipe Variety of axially parallel or helical circumferential ribs that the Improve the heat transfer coefficient on the inside of the pipe.
  • These inner ribs run with a constant cross section parallel to the pipe axis or in the form of Helical lines at a certain angle to the pipe axis. The higher the inner ribs the greater the improvement in the heat transfer coefficient.
  • the manufacture of such pipes is e.g.
  • the object of the invention is to provide heat exchanger tubes structured on both sides to produce performance-enhanced internal structure, the weight percentage of Internal structure of the total weight of the pipe must not be higher than that of conventional, helical inner ribs of constant cross-section.
  • the dimensions the inner and outer structure of the finned tube must be independent of each other be adjustable.

  • the inner ribs Due to the introduction of the secondary grooves, the inner ribs now have no constant Cross section more. If you follow the course of the inner ribs, then changes the cross-sectional shape of the inner ribs at the locations of the secondary grooves. Through the Secondary grooves create additional vortices in the medium flowing on the pipe side area close to the wall, which increases the heat transfer coefficient. It is realizes that by adding secondary grooves the weight fraction of the Internal structure on the total weight of the pipe is not increased.
  • the depth of the secondary grooves is radial from the top of the inner rib Direction measured.
  • the depth of the secondary grooves is at least 20% of the height the inner ribs. If the depth of the secondary grooves is equal to the height of the inner ribs then there are structural elements spaced apart on the inside of the tube, the truncated pyramids are similar.
  • Claims 2 to 13 relate to preferred embodiments of the invention Heat exchanger tube.
  • the invention further relates to a method according to claims 14 to 19 for the production of the heat exchanger tube according to the invention.
  • the invention is used to produce a heat exchanger tube structured on both sides with the proposed secondary grooves in the internal structure Tool for forming the outer ribs in at least two spaced apart Roll plate packages built.
  • the interior structure is different by two profiled mandrels shaped.
  • the first roll dome supports the pipe in the first forming area under the first roll plate package and forms first Helical circumferential or axially parallel inner ribs, these Internal ribs initially have a constant cross section.
  • the second dome supports the pipe in the second forming area under the second roll plate package larger diameter and forms the secondary grooves according to the invention in the previously formed helically surrounding or axially parallel ribs.
  • the depth The secondary grooves are essentially determined by the choice of the diameter of the two Rolling mandrels set.
  • the integrally rolled finned tube 1 according to Figures 1 and 2 has on the outside of the tube helically surrounding ribs 3.
  • the preparation of the invention Finned tube is made by a rolling process (see US Pat. No. 1,865,575 / 3.327.512 and DE 23 03 172) by means of the device shown in Figure 1.

  • the smooth tube 2 is in the case of undelivered rolling tools 11 and 12 almost completely on the mandrels 15 and 16 on the Rod 9 pushed. Only the part of the smooth tube 2, that in the finished finned tube 1 is to form the first smooth end piece, is not on the mandrels 15 and 16 pushed.
  • Rolling tools 11 and 12 are fed radially to the smooth tube 2 and with the smooth tube 2 engaged.
  • the smooth tube 2 is thereby rotated. Since the The axis of the rolling tools 11 and 12 is inclined to the tube axis, form the Rolling tools 11 and 12 helical ribs 3 from the Tube wall of the smooth tube 2 and simultaneously push the resulting finned tube 1 corresponding to the slope of the helical circumferential ribs 3 in Direction of arrow.
  • the ribs 3 preferably run like a multi-start thread around. The distance between the centers of two neighboring measured along the pipe axis Ribs is called the rib pitch p.
  • the distance between the two Rolling tools 11 and 12 must be adapted so that the rolling disks 14 of the engage the second rolling tool 12 in the grooves 4, which are between those of the first Rolling tool 11 are formed ribs 3a. Ideally this distance is one integer multiple of the rib division p.

  • the grooves usually run underneath a swirl angle of 0 ° to 70 ° to the axis of the mandrel. At the first mandrel 15 this helix angle is designated by ⁇ , in the second rolling mandrel 16 by ⁇ .
  • Twist angle 0 ° corresponds to the case that the grooves are parallel to the axis of the mandrel run. If the twist angle is different from 0 °, the grooves run helically.
  • Helical grooves can be left-handed or right-handed be oriented. 1 and 2 show the case where the first Rolling mandrel 15 right-hand grooves 17 and the second rolling mandrel 16 left-hand grooves 18 has. In this case one speaks of oppositely oriented grooves 17 and 18 or of different orientation of the two swirl angles ⁇ and ⁇ . In this case the twist angles ⁇ and ⁇ can have the same amounts.
  • both mandrels 15 and 16 have grooves 17 and 18 with the same orientation.
  • the twist angles ⁇ and ⁇ must differ with regard to their amount.
  • the two mandrels 15 and 16 must be rotatably supported with respect to one another.
  • the inner ribs 20 are caused by the radial forces of the second rolling tool 12 pressed onto the second mandrel 16. Since the grooves 18 of the second rolling mandrel 16 at a different angle to the dome axis and thus at a different angle to the Pipe axis run as the grooves 17 of the first mandrel 15, meet the inner ribs 20 in sections on a groove 18 or a web 19 of the second rolling mandrel 16.

  • the Angle ⁇ is at least 10 °, typically it is in the range between 30 ° and 100 °, preferably between 60 ° and 85 °. Angles y smaller than 90 ° are production-related easier to control than angle y greater than 90 ° and usually cause a smaller pressure drop than angle y greater than 90 °.
