Definitions

  • the invention relates to a heat exchanger according to the preamble of claim 1, a method for producing a heat exchanger according to the preamble of claim 6 and an automotive air conditioning system.
  • a heat exchanger is out US 5,363,910 known.
  • Heat exchangers are used for various technical applications for cooling and / or for heating fluids.
  • a fluid to be cooled or heated to be heated by the heat exchanger and by means of a heat transfer fluid flowing around the fluid in the heat exchanger can be cooled or heated.
  • Heat exchangers generally have a multiplicity of tubes, which are mechanically and hydraulically connected to two manifolds at the ends of the tubes. This creates a hydraulic connection between the two headers and the pipes. Between the tubes, which are designed in particular as flat tubes, are generally corrugated fins. At the manifold is an inlet port and an outlet port for introducing and discharging the fluid to be cooled or heated arranged.
  • a connection device for connecting a line to a connection opening and a fastening device for the line or a device arranged on the line is located at the inlet opening and at the outlet opening.
  • the incoming or outgoing fluid is thus first passed from the line through the connection device and then from the connection device into the inlet or outlet opening on the collection tube.
  • Heat exchangers can also be used as refrigerant condensers in motor vehicle air conditioners and are used for cooling and liquefying a fluid to be cooled, namely refrigerant, which is passed through the refrigerant condenser.
  • connection devices for the heat exchanger are produced by cutting off the individual connection devices from a solid profile or rod produced by means of extrusion.

Furthermore, a mounting hole is incorporated and, for example, a screw is screwed into the mounting hole after incorporating a thread. By means of the screw as a fastening device, a line or a device can be attached to the line to the connection device. At the collecting pipe, a passage is formed at the inlet and outlet openings and the passage is inserted into the fluid opening of the connection device and then soldered. The connection device is thus complicated to manufacture and expensive.
