Definitions

  • the receptacle for the inner tube forms a stop for the face of the end of the inner tube.
  • the inner tube can be pushed into the receptacle designed as a bore, until the end face of the inner tube end rests securely against the stop. This ensures optimal positioning of the inner tube at a predefined depth in the bore.
  • FIG. 3 shows a section of a further embodiment of a heat exchanger according to the invention with a socket-shaped receptacle for the outer tube with an O-ring seal and
  • FIG. 4 shows a section of a further embodiment of a heat exchanger according to the invention with a socket-shaped receptacle for the outer tube with an ear ring and an additional annular groove.
