  • the connection of the second exchanger element to the connection piece is made particularly simple and secure.
  • At least one first channel with a first groove and a second channel with a second groove are particularly preferably provided, wherein a first flat tube of the second exchanger element is received in the first groove and wherein a second flat tube has a projection to the first flat tube and in the second groove is added.
  • each of the flow paths of the second exchanger element is associated with at least one flat tube, each having a plurality of parallel channels.
  • the first, in particular high-pressure-side flow path is assigned exactly one first flat tube
  • the second, in particular low-pressure side Flow path are assigned exactly two flat tubes, wherein the one high-pressure side flat tube between the two low-pressure side flat tubes is arranged.
  • a thermal barrier is provided between two refrigerant-carrying areas of the connection piece. This can be formed in a simple manner preferably as a cross-sectional taper and / or at least partially recess (s) of the connecting piece.

  • the second exchanger element can have, for example, U-shaped flat tubes.
  • the flow paths of the second exchanger element extend substantially perpendicular to the tubes of the first exchanger element and lie in a plane therewith.
  • the available installation space for the first exchanger element regularly requires that the first exchanger element be provided with horizontally arranged tubes in the radiator region of the vehicle, a space for the second exchanger element being provided regularly in a vertical side region of the first exchanger element.
  • the refrigerant flows through the first flow path in a direction opposite to the second flow path.
  • a collector of the refrigeration circuit is not integrally formed with the first and the second exchanger element, thereby taking into account the space requirements.
  • the collector and possibly other parts of the refrigerant circuit are not arranged in the flow of cooling air, which can lead to a disturbance of the efficiency of the refrigeration circuit.
  • thermo barrier formed in particular as an air gap between the first exchanger element and the second exchanger element, thereby avoiding disadvantageous heat flows between the exchanger elements.
  • the heat exchanger according to the invention comprises a first exchanger element 1, which comprises a number of flat tubes 2, which are arranged in parallel and horizontally. Between the tubes 2 there are rib elements 3 which serve to enlarge the surface of the first exchanger element 1.
  • the parallel tubes 1 are all connected at their respective ends with distributor elements 4, 4b.

  • the refrigerant is present carbon dioxide (CO2).
  • CO2 air conditioning systems for motor vehicles a so-called internal heat exchanger is regularly provided, in which the CO2 from one part of the refrigeration circuit experiences a thermal exchange with CO2 on another part of the refrigeration circuit. Due to the peculiarities of the state diagram of carbon dioxide, the provision of such an internal heat exchanger is expedient. In principle, however, an internal heat exchanger can also be useful for other refrigerants.

  • Both the first connector 9 and the second connector 10 are in this case made of a single metal block, but may alternatively be composed of individual parts.
  • the connector 9 is a cuboid with a number of holes or channels for guiding refrigerant and grooves for fixing the flat tubes 6, 7, 8.

  • the third channel 9d also has a slot or groove 9e which has approximately three times the width of the groove 9c and forms an opening of the third channel 9d towards an end face of the cuboid 9.
  • the middle flat tube 7 corresponds to the width of the groove 9c and the thickness of the entire flat tube stack 6, 7, 8 corresponds to the width of the groove 9e.
  • the suitably stepped end portion of the tubes 6, 7, 8 can be inserted into the grooves 9c, 9e and soldered flat with the walls of the grooves. This results in a connection of the channel 9b only with the middle flat tube 7 and a connection of the channel 9d only with the outer flat tubes 6, 8th
  • the second connecting piece 10 has a first channel 10a and a larger second channel 10c, wherein a narrower groove 10b connects the two channels 10a, 10c with each other and a wider groove 10d connects the wider channel 10c to the outside.

  • the refrigerant is fed from the compressor under high pressure and temperature via a feed line 11 into the channel 9a, in which it the first connection piece 9 flows through and opens into the first flow path a of the first exchanger element 1.
  • the refrigerant from the first exchanger element 1 enters the blind-hole-like channel 10a of the second connecting piece 10. From this channel, it enters the flat tube 7 via the previously described connection and passes through the second exchanger element 5 from bottom to top on the flow path e.
  • the refrigerant enters from the flat tube 7 in the Channel 9b of the first connector 9 and is continued via a line 12 to other components of the refrigerant circuit.
  • the refrigerant is at a lower pressure and a lower temperature than in the first exchanger element 1. From here it enters via a feed line 13 in the channel 9d of the first connector 9 and from there into the two outer Flat tubes 6, 8.
  • the refrigerant passes through the flow path f of the first connector 9 from top to bottom to the second connector 10, where it enters the channel 10c of the second connector 10 and subsequently into a conduit 14, over which it again the other components of the refrigerant circuit is supplied.
  • another component such as, for example, a collector with an integrated expansion element can be formed integrally with the second exchanger element 5, so that the connections 11, 12, 13, 14 open directly into this further component.

  • the other components are generally not circulated to ensure the proper efficiency of the air conditioning of the cooling air 15.
  • the second exchanger element 5 is not arranged in the region of the cooling air 15, but causes only a heat exchange between the flow paths e and f of the refrigerant-
  • the flow paths e and f are directed opposite, so that the second exchanger element 5 is operated according to the countercurrent principle ,
  • a slit 16 which crosses through sections of the exchanger element 9, is provided in the first exchanger element 9.
  • a thermal barrier between the channel 9a and the channel 9b is realized, so that at this point undesirable heat exchange between the feeding high-pressure channel 9a and the wegsetden High pressure channel 9b is avoided.
  • the cross-sectional area of the connecting piece 9 is thus tapered in the plane of the slit_
  • connecting pieces 9, 10 is a spaced support of the second exchanger element 5 of the first exchanger element 1, so that between the exchanger elements 1, 5, an air gap 17 remains as a thermal barrier This results in a heat exchange between the flat tubes 6, 7, 8 on the one hand and the adjacent distributor element 4 on the other hand effectively avoided.
