Definitions

  • the innovation concerns a heat exchanger according to the preamble of protection claim 1.
  • a heat exchanger with rectangular tubes (DE 26 24 879 A1) is known in which the tube ends are pressed into conical openings in tube sheets and are kept sealed by deforming elastic collars. In order to be able to compensate for the pressure exerted by the collars, reinforcements in the form of meandering strips are inserted into the pipe ends. Such a design is complex.
  • the innovation is based on the object of designing a heat exchanger of the type mentioned at the outset in such a way that the tubes can be prevented from falling in without the production outlay being too great.
  • the characterizing features of claim 1 are provided in a heat exchanger of the type mentioned.
  • the arrangement of at least one support web between the parallel tube walls makes the flat tubes more stable in the area in which denting is to be feared.
  • the disadvantageous collapse of the pipes on the walls can be avoided.
  • the support web can be produced in a particularly simple manner, in particular according to the features of claims 2 and 3.
  • the tabs can be punched out and bent in a simple manner by means of punching and shaping dies which, after the tubes have been drawn into their corresponding passages in the tube sheets, act on the ends of the tubes at the ends. A separate operation is not necessary for this.
  • the punching and bending of the tabs can be coupled with the cassette process, ie with the process of pulling the tubes into the tube sheet.
  • the pipe ends can be prepared accordingly using the appropriate cut and shape punches, which can be arranged in the bottom press-on receptacle, before the soldering process is carried out.
  • Fig. 1 shows several flat tubes (1) which are arranged parallel to each other with their side surfaces to form a heat exchanger and are held at the ends in a tube sheet (3).
  • the tube sheet (3) which is preferably made of aluminum, is provided in a known manner with a circumferential flanged edge (7) into which the free edge of a hood-shaped water box, for example made of plastic, can be inserted tightly.
  • All flat tubes (1) have a very narrow, long through flow cross-section, whose width (a), (see FIG. 2), is in the order of a few millimeters, preferably even in the order of approximately 1 mm.
  • the flat tubes (1) are also made of aluminum.
  • the flat tubes (1) themselves, if it is a water / air cooler for a vehicle engine, as in the exemplary embodiment, are traversed by water, which is fed to one of the water boxes, not shown, and either deflected or diverted from the other water box.
  • the openings (2) designated as passages are slightly funnel-shaped from one side of the tube sheet (3).
  • the tube ends (1a) of the flat tubes (1) are pushed into these openings in a known manner. If all of the flat tubes (1) are "cassetted" by inserting their tube ends into the assigned tube sheets (3), then a cutting and shaping stamp coupled to the tube sheet receptacle can be placed in the middle - in the plane (M) of FIG. 1 - of the front end (1b) of the two opposite tube walls (4 and 4 ') are each punched out of a tab (6, 6').
  • the tabs (6, 6 ') are simultaneously bent so that they lie against each other with their ends (6a and 6a'), (Fig.
  • this measure creates support webs (5) in each flat tube (1), which lie in the middle (M) of the flat tubes (1) and which are used for stiffening the tube ends (1a) in the area of the tube sheets (3).
  • This support webs (5) prevent that during the subsequent soldering process, in which the tube ends (1a) are soldered to the tube sheets (3), the adverse appearance of the denting of the tube walls (4, 4 ') occurs inwards.
  • the flat tubes (1) can therefore be firmly and tightly connected to the tube sheet (3). The same applies to the tube sheet, not shown, assigned to the other tube ends.
  • the support web (5) is formed by two tabs bent inwards from opposite walls.
  • this embodiment is particularly simple in terms of production technology, it is of course also conceivable to form the support web, for example by punching out and bending a tab, only from one wall.
  • Other possibilities are also conceivable, such as the arrangement of a plurality of support webs distributed over the pipe width. However, such measures require a greater manufacturing effort.
