  • the fastening device is fastened to the first curved and / or to the second curved section of the heat exchanger tube. If the fastening device comprises the two sub-fastening devices, then one of the two sub-fastening devices can be fastened to the first curved section and the other sub-fastening device can be fastened to the second curved section.
  • the fastening device or the two partial fastening devices are each formed according to the first alternative semi-cylindrical. Then it is possible to fasten the fastening device with its circular segment-shaped lateral surface on the first curved or on the second curved portion of the heat exchanger tube. If the fastening device has the two partial fastening devices, which may each have a semi-cylindrical shape, then one of the partial fastening devices with its circular-segment-shaped lateral surface on the first curved section and the other partial fastening device with its circular segment-shaped Jacket surface be attached to the second curved portion of the heat exchanger tube.

  • the partial fastening devices 14, 15 are each formed in a semi-cylindrical shape and have a height which corresponds to the height h of the condenser 5.
  • One of the partial fastening devices 14 is attached to the condenser tube 6 in the region of the curved section 10 of the condenser tube 6 and the other partial fastening device 15 is fastened to the condenser tube 6 in the region of the curved section 11 of the condenser tube 6.
  • the radii of the semi-cylindrical sub-fixing devices 14, 15 thus correspond to the radii of the two semicircular curved sections 10, 11 of the condenser tube 6.
  • the curved condenser tube 6 with attached thereto partial fastening devices 14, 15 is in the Fig. 4 shown.
