Definitions

  • the invention relates to a heat exchanger with at least one flange-provided plastic water tank and a tube sheet carrying a deformable edge area, between which an elastic seal is held under prestress, the deformable edge area running parallel to the flange outer contour before it is deformed and after its production of a clamp connection over the flange of the plastic water tank has approximately wave-shaped deformed first partial areas and non-deformed further partial areas running parallel to the flange outer contour and the first partial areas deformed over the flanges or the flanges of the plastic water tank form the positive connection, in each case the lower edge of the deformed first partial areas on the top or the top of the or the flanges bear under prestress and, in order to facilitate the deformation, the deformed first partial region is parallel and at a distance from an outer edge in H. height of the flange edge or Flanschoberkanten are cut free.
  • Such a heat exchanger is known from DE-OS-28 52 408.
  • the flange of the plastic water tank in particular must be manufactured with tight tolerances. Nevertheless, leaks can occur due to slight unevenness and warping of the plastic.
  • the object of the present invention is to design the heat exchanger described at the outset in such a way that a tight clamping connection is ensured even in the case of greater manufacturing tolerances.
  • the invention provides that the upper side of the flange or the flanges of the plastic water tank have an inclined surface at least partially in the region of the deformed first partial regions, that this inclined surface or inclined surfaces fall towards the flange outer contour and that the lower edge of the deformed first partial regions are deformed in each case over this inclined surface or inclined surfaces.
  • the clamp connection is closed by deforming the first partial areas, the lower edges also slide open to increase the pretension of the elastic seal, which is already pretensioned during assembly during the closing process.
  • a saving of material while at the same time keeping the wall thicknesses constant also in the area of the flange can be achieved in that the flange of the plastic water tank has shaped locking cams and that these locking cams carry the inclined surfaces. Due to the essentially identical wall thicknesses of the plastic water tank, the cooling time during production can be kept short at the same time and a more even filling is achieved during the spraying process, combined with less internal stresses, so that this also improves the dimensional accuracy due to less warpage.
  • the helix angle of the inclined surfaces of the flange is approximately 10 ° with respect to the sealing surface.
  • Figures 1 to 3 show the clamp connection of a heat exchanger, in particular a radiator for motor vehicles in finished, i.e. closed state. It is a plastic water tank 1 and a tube sheet 2 made of metal, which are connected to one another with the interposition of an elastic seal 3 in a liquid-tight and pressure-tight manner. Both parts form the collecting container of a heat exchanger, which is not shown completely, for example a radiator for motor vehicles.
  • the seal 3 is received in a U-shaped outer edge 6 of the tube sheet 2 together with a likewise circumferential flange 4 of the plastic water tank 1.
  • the outer and upper part of the outer edge 6 alternately consists of deformed first partial regions 7 and non-deformed further regions 8.
  • the deformable region 5 therefore has Outer edge 6, as can be seen in Figure 3, a waveform.
  • the deformed first section 7 of the tube sheet 2 must be cut free. In the exemplary embodiment, this takes place through elongated holes 10, the lower edges 9 of which are bent over the flange 4 and are an integral part of the clamp connection.
  • the flange 4 is provided with raised closing cams 11, the outer contours 12 of which are aligned with the flange outer contour 12 'and which have an inclined surface 13 on their upper side.
  • the helix angle 14 of these inclined surfaces with respect to the sealing surface 15 of the tube sheet 2 is approximately 10 °.
  • Plastic water tanks 1 with relatively large manufacturing tolerances, in particular also the flanges 4 with their locking cams 11, can therefore be used without disadvantages, so that significantly fewer rejects have to be sorted out and the tightness of the heat exchangers is nevertheless ensured even at higher internal pressures and higher temperatures.
