  • the condenser 1 is connected to a not shown refrigerant circuit of the air conditioner.
  • the condenser 1 furthermore has four holders 8, 9, 10, 11, two of which are each attached to the collecting pipes 3, 4.
  • the capacitor in the motor vehicle in particular on an adjacent heat exchanger, such as a coolant cooler, not shown, suspended.
  • the network 2 of the condenser 1 is flowed through by ambient air, to which the refrigerant gives off its heat of condensation.
  • Fig. 2 shows the refrigerant connection flange 5 in a perspective view of the manifold 3, which is only partially shown.
  • the flange 5 is an extruded part, which has a fork-shaped profile piece 12, a web 13 and a refrigerant connection area 14 with refrigerant connection holes 14a, 14b, 14c (another hole is covered).
  • the flange 5 is fixed by soldering on the manifold 3.
  • Fig. 3 shows the holder 8 (by way of example for the remaining holders, 9, 10, 11), which is also made as an extruded part of an aluminum extrusion alloy.
  • the holder 8 consists of a fork-shaped profile piece 15, which surrounds the manifold 4 partially, from a bent web 16 and a mounting piece 17 with mounting hole 8a.
  • the holder 8 is soldered via the profile piece 15 with the manifold 4.
  • Fig. 4 shows the flange 5 (of FIG. 2) in a sectional view (without hatching).
  • the manifold 3 is formed in two pieces, ie, it has a lid part 3a, which is inserted into a bottom part 3b of larger diameter and forms with this lateral overlap zones 3c, 3d, via which lid 3a and bottom 3b are soldered together.
  • the bottom 3b has passages (transverse slots) 3e, in which the pipe ends, not shown, of the flat tubes are inserted and soldered.
  • the bottom 3b is bounded at the top by upper edges 3f, 3g, which form shoulders with the lid 3a on the outside.
  • the fork-shaped profile piece 12 has two legs 12a, 12b arranged parallel to one another, which comprise the collecting tube 3 in the region of the overlapping zones 3c, 3d.
  • the legs 12a, 12b are significantly extended beyond the overlapping zones 3c, 3d, so that the profile piece 12 encloses significantly more than half the circumference of the collecting tube 3.
  • the center point M of a circle with the diameter of the half-shell-shaped bottom 3b and four circle quadrants are shown in the manifold 3.
  • Fig. 5 shows a modified embodiment of a flange 18 with a modified profile piece 19, which is also fork-shaped and consists of a curved piece 19a and two adjoining, substantially parallel legs 19b, 19c.
  • a modified profile piece 19 On the inside of the profile piece 19 19a to the lateral legs 19b, 19c paragraphs 20, 21 are arranged in the region of the transition of the elbow piece.

  • the profile piece 15 for the holder 8 corresponds in principle to the profile piece 12 for the flange 5 (cf., Fig. 4).
  • Fig. 7 shows the holder 8 with profile piece 15 and the two-piece manifold 4 before assembly.
  • the manifold 4 is located in a device, not shown, and the holder 8 is placed with its profile piece 15 on the manifold 4 so that then results in a clamping or interference fit.
  • the profile piece 15 has a clear width LW
  • the collecting tube 4 has an outer diameter DA, wherein LW ⁇ DA.
  • the profile fork 15 thus has an undersize with respect to the outer diameter or this an excess compared to the width of the profile fork.
  • the difference or the excess DA - LW 0.1 mm.
  • the profile fork 15 For mounting the profile fork 15 is spread by a device, not shown, ie widened with respect to the inner dimension LW until a postponement of the manifold 4 is possible. After reaching the end position (stop), the legs of the profile fork are relieved by the device and thus come under pretension to rest on the overlapping areas of the manifold 4.
  • the bias depends on the selected oversize or undersize. The bias moves in the elastic region of the material of the holder 8, ie an aluminum extruded alloy - when spreading the profile fork 15 so no plastic deformation may occur. By thus achieved clamping fit of the holder is fixed to the manifold 4 for the subsequent soldering process.
  • the solder is available as Lotplatt ist available, which is applied on both sides of the bottom of the manifold 4 and on the outside of the lid.
  • the soldering takes place by the so-called Nocolok method, ie before soldering, in this case also before the joining of the parts 8 and 4, a suitable flux is applied in a suitable form.
