Definitions

  • the invention relates to a flat tube for a heat exchanger of the type specified in the preamble of claim 1.
  • Such a flat tube is known for example from DE-C-32 16 140.
  • the flat tubes according to the prior art are soldered to the tube seam after the metal strip has been bent.
  • an integrally formed support web is provided in the known flat tube, which is supported on the opposite side of the flat tube. This support web is arranged in a lateral area of the pipe cross section.
  • a major advantage of the flat tube according to the invention is that the support web simultaneously serves as a tie rod without any additional effort, as a result of which the flat tube can also withstand high internal pressures.
  • This configuration results in two separate chambers in the flat tube, each of which is sealed off by corresponding soldering surfaces. To the outside of the tube there is a common soldering surface on the tube seam, so that each chamber of the flat tube is sealed against the outside by means of two soldering surfaces.
  • the support web acting as a tie rod has twice the thickness of the normal tube wall thickness, so that a high force load is guaranteed.
  • additional support webs extending in the longitudinal direction of the tube are provided, which are formed by inwardly directed folds of the metal strip.
  • This measure means that the flat sides of the flat tube are mutually opposed at several points in the cross section supported and the support webs soldered to the inner tube wall, so that this embodiment is suitable for extremely high loads both from the inside and from the outside.
  • the metal strip 1 shows a flat tube 2 bent from a metal strip, the cross section of which is determined by two flat sides 3 and 4 and in the lateral end regions by arches 5 and 6.
  • the two edges of the metal strip 1 are brought together on the flat side 4 and angled twice towards the flat side 3 in the same direction, so that each edge of the metal strip 1 has a support web 7, 8 and a contact surface 9, 10 on the inside of the Flat side 3 forms.
  • the two support webs 7 and 8 lie against one another and thereby form an overlapping region 14.
  • the metal strip 1 is a material that is solder-plated on one side, the solder plating being arranged on the side. which forms the outside of the flat tube 2.
  • this is an extremely flat tube which, for example, consists of a 0.4 mm thick sheet metal strip and has an outer tube dimension of 40 mm ⁇ 2 mm.
  • this information is only to be understood as an example; other material thicknesses and other cross-sectional dimensions could also be selected.
  • the flat tube it is of course possible for the flat tube to be passed through an HF welding device after the bending process, as a result of which the tube seam is tacked but not sealed. This measure can be taken in order to give the tube seam an additional strength in addition to the soldering connection which takes place later, which should however only be necessary in exceptional cases.
  • FIG. 2 shows an enlarged representation of the detail X in FIG. 1. This representation clearly shows three solder seams 11, 12, 13 which are present between the support webs 7 and 8 and between the contact surfaces 9 and 10 and the flat side 3 .
  • FIG. 3 shows a cross section through a flat tube which is configured similarly to the flat tube 2 described for FIG. 1.
  • the same reference numerals as in FIG. 1 are therefore used for matching parts.
  • the metal strip 1 is folded at two points in such a way that additional support webs 18 extend in the longitudinal direction of the tube and bear against the inside of the opposite flat side 4. If the metal strip 1 is a double-sided solder-plated material, the contact surfaces of the additional support webs 18 are also soldered to the inside of the flat tube.
