Definitions

  • the invention relates to a heat exchange tube with an inner structured surface according to the preamble of the claim 1 (see, for example, JP-A-4 / 158.193) or claims 2/3 (see, for example, DE-A-196 28 280).
  • the heat exchange tube is esp. for the evaporation of liquids from pure substances or Mixtures suitable on the inside of the pipe. But it also offers Advantages in the condensation of vapors.
  • the Heat exchange tubes are often in between evaporation and Condensation switchable fin block heat exchangers used and are mostly horizontal in the Finned block heat exchanger installed.
  • the object of the invention is to provide a heat exchange tube with a to create inner surface structure which has the advantages one that is good or improved compared to the prior art Evaporation performance and at the same time one compared to that State of the art reduced pipe weight and a reduced according to the number of working and rolling steps Production effort connects.
  • the object is achieved in heat exchange tubes according to the preamble of claims 1, 2 and 3 according to the invention in that the fins in the individual zones (Z 1 to Z m ) in the longitudinal direction of the tube in any periodic combination and sequence of at least two fin heights (H 1 to H n , H 1 > H 2 >...> H n ) are arranged, adjacent zones (Z 1 to Z m ) adjoining one another in such a way that at the transition of two zones the rib sequence in the pipe longitudinal direction is offset by at least one rib.
  • Claims 4 to 19 relate to preferred embodiments the heat exchange tubes according to the invention.
  • the production of the heat exchange tube according to the invention is based on the example described in more detail below Method.
  • copper or a copper alloy used as the material of the heat exchange tubes but the present invention is not so limited.
  • Much more any type of metal can be used, e.g. Aluminum.
  • a metallic ribbon is a one-step Subjected rolling embossing step in which there is between one Structural roller with a complementary to the structure according to the invention Surface design and a backup roller passed becomes.
  • One side of the ribbon is used provided the structure of the invention, while the second Side remains smooth or one not described here in more detail Has structuring. Only the one below Welding edge areas of the first page can may be structured differently or unstructured stay.
  • the structured Flat ribbon molded into a slotted tube in one Welding process longitudinally welded and the pipe if necessary in a final drawing process to the desired one Brought outside diameter.
  • a possible influence on the Heat transfer capacity of the heat exchange tube according to the invention due to the different surrounding of the weld structured or unstructured area is insignificant and can be neglected.
  • the claim 20 relates to the preferred embodiment of a Structural roller for the production of the heat exchange tubes according to the invention.
  • the modular structure of the roller from disks or wrestling, the quick creation and evaluation of numerous Structure variants within the framework of an experimental plan and a rapid adaptation of the surface structure to new fluids and changed operating conditions by changing the number, shape and (groove) geometry of the disks and rings or by exchange individual disks / rings according to the modular principle enables, shows up as a further advantage of the invention.
  • Fig. 1 shows a fin block heat exchanger after State of the art with horizontally arranged heat exchange tubes 1 and not numbered slats.
  • Fig. 2 is a longitudinal section of a longitudinally welded Heat exchange tube 1 shown with the outer diameter D.
  • the heat exchange tube 1 has a smooth outer surface and a structured inner surface.
  • FIG. 3 schematically shows a top view of the opened inner surface of such a finned heat exchange tube 1.
  • the inner surface is divided into four zones (Z 1 to Z 4 ) in the longitudinal direction of the tube (see arrow direction).
  • zones (Z 1 to Z 4 ) alternately (in the longitudinal direction of the tube) high fins 2 (fin height H 1 ) and low fins 3 (fin height H 2 ) are formed, which are separated from one another by grooves 4.
  • the ribs 2, 3 - and the grooves 4 - run obliquely to the pipe longitudinal direction, ie the center lines 5 of the ribs 2, 3 form the pitch angle ⁇ with the pipe longitudinal direction.
  • Adjacent zones (Z 1 to Z 4 ) are offset from one another such that a high rib 2 and a low rib 3 collide at the boundaries of the zones (Z 1 to Z 4 ).
  • the rib length within a zone, measured along the center lines 5 of the ribs 2, 3, is designated by L.
  • FIG. 4 shows in detail the rib pitch t (distance from rib center to rib center, measured perpendicular to the rib center lines 5), the flank angles ⁇ 1 and ⁇ 2 , the rib heights H 1 and H 2 and the rib foot widths F 1 and F 2 , The flank angles ⁇ 1 , ⁇ 2 and the foot widths F 1 , F 2 are also measured in a cross-sectional plane perpendicular to the rib center lines 5.
  • FIG. 5 shows schematically and analogously to FIG. 3 a top view on the opened inner surface of a finned heat exchange tube 1, at the high and low ribs at the transition adjacent zones each through a gap 12 of length B (measured along the elongated center lines 5 of the ribs 2, 3) are separated from each other.
  • FIG. 6 schematically shows the structure of a structure roller 6 for Production of the heat exchange tubes 1 according to the invention shown.
  • the roller 6 is constructed from a plurality of disks 7 which are offset from one another in the circumferential direction. Deep and less deep grooves 8, 9 are alternately introduced into the individual disks 7, which produce the high ribs 2 and the lower ribs 3 in the individual zones Z 1 to Z 5 when the roller 6 rolls on the sheet metal strip 10 in a roll stamping process. After structuring, the sheet metal strip 10 is formed into a slotted tube and welded lengthwise (weld seam 11).
  • FIG. 7 and 8 show an embodiment with four zones each (Z 1 to Z 4 ), with FIG. 8 differing in the additional arrangement of columns 12 of length B between high ribs 2 and low ribs 3. These relationships are illustrated by the illustration in FIG. 5.
  • the inner surface of the heat exchange tube 1 according to FIG. 9 is divided into 6 zones (Z 1 to Z 6 ).
  • group G 1 with the three zones (Z 1 to Z 3 )
  • the ribs 2, 3 run at the pitch angle ⁇
  • the inner surface of the heat exchange tube 1 according to FIG. 10 is also divided into 6 zones (Z 1 to Z 6 ).
  • groups G 1 and G 3 with zones Z 1 / Z 2 and Z 5 / Z 6 the ribs 2, 3 run at the pitch angle ⁇ , in group 2 with zones Z 3 / Z 4 at a different pitch angle
  • each zone contains exactly one high and one lower rib 2, 3 in a cut in the circumferential direction, so that a total of 19 high ribs 2 and 19 lower ribs 3 result in the circumferential direction.
  • An angle of 90 ° is set as the offset of the zones or as the angular offset of the disks 7 of the structure roller 6 relative to one another.
