Definitions

  • the invention relates to a tube with twisted inner fins rotationally symmetrical to the longitudinal axis of symmetry of the tube run.
  • a known pipe of this type according to DE-GM 74 22 107 has several multi-start screw-like on its inside Inner ribs that have a small width b and a small radial Extend e.
  • a heat exchanger is known from EP 0 582 835 A1 become known, which consists of several, in their outer wall tiered, non-generic tubes composed in their Interior with other differently configured pipes different dimensions and inner ribs concentric are arranged to serve as an oil cooler.
  • This Heat pipes are next to their elaborate manufacture suffers from the disadvantage of considerable pressure loss because also - if it exists at all - one that Cross flow increasing heat transfer either not or can only arise accidentally and on the inner tube remains limited.
  • the invention is based on the object Heat transfer tube of the type mentioned at the beginning create, which is compared to the previously known internally finned tubes by a much better Heat transfer performance distinguishes itself and for this purpose not just an increase in the internal heat transfer area served, but also an effective cross flow between the Inner wall surface of the tube and the core flow near the Longitudinal axis of symmetry to increase heat transfer guaranteed.
  • the Cross-sectional shape of each rib is a pointed, isosceles Triangle with straight leg sides, the Triangle tip rounded by a radius in the two Leg sides merges, with two adjacent inner ribs form a space trapezoidal in cross section.
  • This Cross-sectional shape is in principle from DE 33 34 964 A1 known, but there the ribs run without any twist, so that it in conjunction with the swirl features of claim 1 are not known as known.
  • each inner fin of the tube is the shape of a Tooth in the case of gears with convexly curved flanks with a rounded tooth tip, with two adjacent ribs a cross-sectionally U-shaped space with concave grasp sunken side surfaces.
  • This rib shape is particularly suitable for high viscosity fluids such as oils.
  • each inner rib an isosceles, pointed triangle with concave legs and a semicircular shape at the top, with two adjacent ones Inner ribs a space trapezoidal in cross section Grip in a U-shape, the trapezoidal legs convex to the outside are arched.
  • This rib shape is preferably used in the Flow of fluids of low viscosity, like them have gases, for example.
  • the wall thickness of the tube is dependent on System pressure is determined and is advantageously in a range between 0.4mm and 3mm, with each tube having at least four inner fins having.
  • the distance a is the free ends of the inner ribs from the axis of symmetry of the Tube with large viscosity fluids, such as with oils, larger and Low viscosity fluids such as water and gases are lower sized. This increases the cross section of the Core flow in the area of the free cross section near the Longitudinal axis of symmetry for fluids with high viscosity Low viscosity fluids.
  • the free interior near the The longitudinal axis of symmetry is never closed in any tube become. This space must be with the channels between the ribs communicate. For this reason, point in an advantageous Training the free ends of the inner ribs from the Longitudinal axis of symmetry, even with low viscosity fluids such a distance a from this that between its free Obtain a core flow channel ends in each cross section of the tube remains. For this reason, according to feature a) of Main claim this distance a is not less than 1/12 of Pipe inner diameter are dimensioned.
  • Fig. 1 is a first embodiment of the tube 1 according to the invention shown.
  • the forms Cross-sectional shape of each rib 2 is a pointed, isosceles Triangle with straight leg sides 2a, 2b, the Triangle tip 2c rounded into the two by means of a radius r Leg sides 2a, 2b merges.
  • Two adjacent ones Inner ribs 2 form a trapezoidal cross section Gap 2d.
  • each inner rib 3 of the tube 1 the shape of a tooth in gearwheels with convex externally curved side flanks 3a, 3b with a rounded Tooth tip 3c.
  • Two adjacent ribs 3 encompass one in cross section U-shaped space 3d with convex sunken side faces that are identical to the shape of the Side flanks 3a, 3b of the ribs 3 are.
  • FIG. 3 A further cross-sectional shape is disclosed in FIG. 3. there forms the cross section of each inner rib 4 isosceles, pointed triangle with concave inside incident leg sides 4a, 4b with a semicircular Tip 4c. Grip two adjacent inner ribs 4 at a time U-shaped, a space 4d trapezoidal in cross section, whose trapezoidal legs are convexly curved outwards and are identical to the leg sides 4a, 4b.
  • Each tube 1 is with at least four inner ribs 2, 3, 4, in present case with eight inner ribs 2, 3, 4 each.
  • the free ends 2c, 3c, 4c are with the tips of the cross-sectional shapes of the individual inner ribs 2, 3, 4 identical. However, it must note that the tips are on the flat Cross-sectional body of a triangle, however, the free ends themselves on a twisted to the longitudinal axis 5 of symmetry refer to the spatial body.
  • These free ends 2c, 3c, 4c have to the longitudinal axis of symmetry 5 of the tube 1 at a distance a in Relation to the inner pipe diameter d in a range of 1:12 to 1: 3.
  • the tubes are advantageously either extruded Made of aluminum or copper or extruded in plastic.
  • the wall thickness d 1 of the pipe 1 depends on the system pressure and is in a range between 0.4 mm and 3 mm.
  • the tubes 1 also from other than that in the pipes 1 to 3 shown may consist of that instead of the eight ribs 2, 3, 4 shown there, for example, only four Ribs 2, 3, 4 or more than eight ribs in the interior of tube 1 are arranged.
  • the number of ribs 2, 3, 4, the length L of the Twist as well as the thickness and rib shape are dependent on the type of fluid and its flow rate as well designed by the pressure drop.
  • the general flow rule applies that the narrower the free pressure, the greater the pressure drop Flow cross section in the core area and between the Single ribs 2, 3, 4 is that on the other hand with larger Number of ribs and the associated larger Heat transfer area also the heat transfer performance passively increases.
  • the swirl and the transverse flow thereby induced between the core area in the vicinity of the longitudinal axis 5 of symmetry and the tube inner wall 9 are of fundamental importance. This is illustrated in Fig. 5.
  • a core flow 7 is formed, which due to the swirling of the end regions, which coincide with the ends of the tips 2c, 3c, 4c agree, a swirl is given, which is a left-hand swirl in the case shown, ie is connected to a rotation in the plane of the drawing in the counterclockwise direction, as indicated by arrow 6 in FIGS. 4 and 5.
  • Such a tube 1 is used, for example a tube bundle heat exchanger 12, as shown in Fig. 6.
  • the cooling medium enters through the connector 13 the tubes 1 and leaves them through the outlet 14.
  • the medium to be cooled for example, flows through the countercurrent Inlet connector 15 on the outside 11 of the tubes 1 and leaves the heat exchanger 12 in the cooled down state by the Outlet port 16.
  • the inventive Tube 1 for both cooling and heating fluids Can be used depending on the direction in which the Heat transfer process should take place.
