Definitions

  • the invention relates to a flat tube for a heat exchanger of the type specified in the preamble of claim 1.
  • a flat tube is known for example from DE-OS 25 06 434.
  • the flat tubes according to the prior art are welded to the tube seam after the metal strip has been bent. In order to prevent the so-called collapse - this is the reduction in the distance between the narrow sides to one another - a molded support web is provided in the known flat tube.
  • An essential advantage of the flat tube according to the invention is that the tube is initially only produced by bending the metal strip and the sealing of the tube by means of welding is not necessary.
  • the pipes that have not yet been sealed are interspersed with corrugated fins or provided with fins, then the pipe bottoms are attached and the side parts are attached, and only then are the parts mentioned soldered in a single operation.
  • a preferred embodiment of the flat tube according to the invention is that the overlapping loading is richly formed by two parallel, adjacent support webs and as contact surfaces on the adjacent tube flat side of each of the support webs has a right-angled edge, the edges being angled in the opposite direction.
  • This configuration results in two separate chambers in the flat tube, each of which is sealed by corresponding soldering surfaces. To the outside of the tube there is still a common soldering surface on the tube seam, so that each chamber of the flat tube is sealed off from 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.
  • a variant of this arrangement consists in that the support web and the contact surface are formed by an edge of the metal strip which is angled twice in the same direction and are arranged approximately in the middle of the flat sides.
  • this embodiment variant is somewhat simpler in terms of its design, the support web acting as a tie rod is only designed in a simple tube wall thickness. Compared to the embodiment mentioned in claim 3, a chamber of the flat tube is only sealed against the outside by a soldering surface.
  • the metal strip is solder-plated on the side forming the outside of the tube.
  • the support web and the contact surface is formed by an edge of the metal strip bent twice in the opposite direction and arranged approximately in the middle of the flat sides.
  • the metal strip is solder-plated on the side forming the inside of the tube.
  • a further embodiment of the flat tube according to the invention consists in that at least a part of the metal strip extends substantially into the vicinity of the edge areas within the flat tube, which thus forms a turbulence insert formed in one piece with the flat tube and which has at least one contact surface approximately in the middle of the flat sides has on each flat side of the flat tube.
  • the turbulence insert which also takes over the function of the support web or tie rod, is produced at the same time without any appreciable additional expenditure of material.
  • the part of the Me tallstMails which forms the turbulence insert, is rolled thinner than the part forming the pipe wall.
  • An embodiment has proven to be particularly expedient in which the region forming the tube seam is arranged near one of the lateral ends and, seen in the cross section of the flat tube, the turbulence insert extending inside the flat tube is zigzag, wave or meandering.
  • the lateral arrangement of the pipe seam makes it possible for the turbulence insert to extend into both end regions of the pipe cross section. Due to the zigzag, wave or meandering design, there are several contact points of the turbulence insert between the flat sides, whereby several supporting webs or tie rods are formed.
  • cutouts and / or turbulators for example in the form of angled sheet metal tabs, can be provided in the part of the metal strip forming the turbulence insert.
  • the metal strip is solder-plated on both sides.
  • 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 in each case angled twice in the same direction in the direction of the flat side 3, 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 area 14.
  • the metal strip 1 is a material that is solder-plated on one side, the solder plating being arranged on the side that forms the outside of the flat tube 2.
  • the flat tube 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 x 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 pipe seam an additional strength in addition to the soldering connection that takes place later, but this should 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 the sheet metal strip 1 bent into a flat tube 2, which has the overlapping region 14 approximately in the middle of the flat side 4.
  • An edge of the sheet metal strip 1 is angled starting from the overlapping area in the direction of the flat side 3 and thus forms a support web 15 a further fold of the edge of the sheet metal strip 1 in the same direction results in a contact surface 16 on the flat side 3 of the flat tube 2.
  • the parts of the sheet metal strip 1 lying against one another are soldered to one another.
  • FIG. 4 shows an embodiment variant of the detail Z in FIG. 3, which, however, instead of the contact surface 16 has a contact surface 17 which is angled in the opposite direction.
  • the remaining reference numerals correspond to those in FIG. 3. While preferably a metal strip 1 with a surface plated with solder on the outside of the tube is used in the embodiment according to FIG. 3, the solder plating can only be provided on the inside of the tube or on both sides in the embodiment according to FIG. 4.
  • FIG. 5 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 in two places 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.
  • Fig. 6 shows a flat tube 19, which consists of a metal strip 20.
  • the metal strip 20 is shaped such that it has an overlapping area 21 near a lateral end 22.
  • the flat tube 19 has flat sides 23 and 24 and a further lateral end 25.
  • the metal strip 20 is angled in the direction of the flat side 23 to form a support web 26, which is adjoined by a contact surface 27 formed on the flat side 23 by angling in the same direction.
  • the metal strip 20 extends from the contact surface 27 in the direction of the lateral end 25 through the interior of the flat tube and thus forms a turbulence insert 28.
  • This turbulence insert 28 essentially comprises two flat sections 29 and 30 in which recesses 31 are provided. Approximately in the middle of the flat sides 23 and 24 of the flat tube, the turbulence insert 28 is configured in a meandering manner between the two flat sections 29 and 30, so that contact surfaces 32 and 33 on the flat sides 23 and 24 and a support web 34 located in between result.
  • the turbine insert In the area adjacent to the lateral end 25, the turbine insert is designed in the same way as between the flat sections 29 and 30, so that there are further contact surfaces 32 and 33 with a support web 34 located between them.
  • Fig. 7 the cross section through a flat tube 19 is shown, which is also formed from a metal strip 20 and the outer contour of which Flat sides 23 and 24 and the lateral regions 25 and the overlap region 21 correspond to those of FIG. 6.
  • the part of the metal strip which is located within the flat tube 19 and which forms the support web, the contact surfaces and the turbulence insert is designed differently.
  • a support web 35 is designed as an arch, the end of which is located away from the overlap area 21 serves as a contact surface 36 on the flat side 23.
  • the metal strip 20 extends as a turbulence insert 37 in a zigzag shape from the contact surface 36 to the vicinity of the lateral end 25.
  • contact surfaces 38 on the flat sides 23 and 24 result which the turbulence insert 37 is soldered to the flat sides 23 and 24.
  • the end of the turbulence insert 37 forms an arcuate support web 35 which is designed in the same way as is also provided near the overlap region.
  • punched openings 39 are provided, through which the turbulence of the pressure fluid is increased.
  • Fig. 8 shows a similar arrangement as Fig. 7, therefore the reference numerals for the same parts match.
  • the difference, however, is that the openings 39 are not formed by punched holes, but by angled sheet metal parts, as a result of which the surface of the turbulence insert which is acted upon by the heat exchanger fluid is larger than that of FIG. 7. Furthermore, turbulence is created by such a configuration the flow further improved.
  • the metal strip can have different thicknesses, which can be taken into account without difficulty when rolling the sheet metal strip.
  • This has the advantage that the sheet metal strip 20 is made thicker over the width that forms the tube wall of the flat tube 19, for example with a wall thickness of 0.3 mm and the part that adjoins the support web 26 or 35 and the Turbulence insert 28 or 37 forms, only has a thickness of 0.1 or 0.15 mm. Because of the mutual contact surfaces of the turbulence insert on the flat sides 23 and 24, the metal strip 20 must be selected from a material soldered on both sides for these embodiments.
