  • the heat exchanger is arranged in a heat exchanger arrangement in conjunction with a carrier and in which the heat exchanger is arranged, wherein the carrier has a receptacle which corresponds in its internal dimensions at least in one direction to the outer dimensions of the collector with lamella (s).
  • the lamella (s) need not necessarily rest positively on the outside, but rather a play can also be provided, in particular to compensate for thermal expansions of the heat exchanger, as may also be the case with conventional heat exchangers. Possibly. can be provided between collector and recording elastic elements, which prevent noise and also prevent air from flowing past.
  • the receptacle preferably has a curved, in particular preferably circular, curved cross-section.

  • a medium is, smaller, in particular at least 20%, preferably at least 35%, more preferably at least 50% smaller than the cross section in the interior of the receptacle.
  • refrigerant R134a is preferably used, but it can also be any other refrigerant can be used, which is suitable because of its properties for a corresponding heat exchanger.
  • a dryer / filter unit is preferably provided.
  • Granules are preferably provided in the dryer / filter unit, however, another suitable filter material, such as, for example, a fabric, may also be provided.
  • Such a heat exchanger with a collector is preferably used as a condenser, which serves the air conditioning of a motor vehicle.
  • a heat exchanger in the present case a condenser 1, is arranged in a refrigerant circuit (not shown) of a motor vehicle air conditioning system in which the refrigerant R134a is circulated.
  • the condenser 1 has a tube / fin block 2 forming a heat transfer area with a plurality of flat tubes 3 and corrugated fins (not shown) arranged therebetween.
  • the flat tubes 3 are arranged extending between two manifolds 5, wherein they protrude through slot-like openings in the bottom of the manifolds 5. Parallel to one of the manifolds 5, in Fig. 1 shown on the right, a collector 6 is arranged.
  • a small gap is formed, wherein two overflow openings are provided for a fluid connection of manifold 5 and 6 collector.
  • a partition wall between the two overflow openings is arranged for deflecting the refrigerant flow.
  • the present extruded collector 6 is closed at the top and bottom with lids.
  • a dryer / filter unit (not shown) used.
  • a granulate is arranged in a manner known per se, for which purpose the walls of the dryer / filter unit are in the form of a grid, so that the refrigerant can flow in and out.
  • the entire capacitor 1 is arranged in a receptacle 10 of a carrier 11, which is firmly connected to the structure of the motor vehicle, and by means of which the capacitor 1 is fixed in the motor vehicle.
  • the collector 6 of the condenser 1 Compared to collectors conventional capacitors, which can be used instead of the inventive capacitor 1 in the recording, formed with a reduced inner cross-section, so that despite the reduced amount of refrigerant due to the lower collector volume, the receptacle 10 does not need to be changed. Since the outer dimensions of the collector 6 and thus of the entire capacitor 1 would be changed by the reduction of the inner cross section, two fins 7 and 8 are sprayed on the outer circumferential surface of the collector 6, which match the dimensions of the inventive capacitor 1 to those of the conventional capacitor. According to a variant, the slats can also be extruded directly with the profile of the collector.
  • the lamellae 7 and 8 are in the radial direction with respect to the theoretical center longitudinal axis of a conventional collector to the outside, wherein they are arranged at an angle of present 90 ° to each other.
  • the shorter lamella 7 extends in the width direction of the condenser 1 and the longer lamella 8 extends in the depth direction of the condenser 1.
  • the lamellae 7 and 8 serve not only to compensate for the smaller dimensions of the collector 6 according to the invention, but also stiffen the profile of the collector 6th
  • the receptacle 10 has, as in particular Fig. 4 can be seen, a substantially semicircular receiving cross-section, which is slightly elongated on one side in the tangential direction.
  • the collector 6 is arranged with a part of its cross section in this semicircular receiving cross section, wherein the blade 7, which extends in the width direction of the capacitor 1, is completely accommodated in the receiving cross section, but the blade 8 is presently arranged in an end region of the receiving cross section.
  • the collecting tube 5 is arranged outside the receiving cross-section. How out Fig. 4 it can be seen, is the capacitor taken in the area of the collector 6 in the depth direction only with little play in the receptacle 10, while in the present case a larger game is provided in the width direction.
  • a cap 20 is set, which also serves to compensate for the reduced outer dimensions of the collector 6 according to the invention in comparison to previously used in the corresponding receptacle 10 collectors, i. the outer dimensions in at least one cross-section at least partially correspond to those of a conventional collector, such that the collector 6, which is disposed with one end in the cap 20, in conjunction with the cap 20 at the corresponding end substantially, i. at least in two directions, in particular in two mutually perpendicular directions, which has dimensions of a conventional collector.
  • the cap 20 is injection-molded from plastic in the present case. It has an outwardly projecting arm 21, by means of which it can be clipped to the carrier 10 or otherwise secured. It compensates, inter alia, the game between capacitor 1 and 10 recording.
