  • a heat exchanger comprising a first heat exchange row and a second heat exchange row overlapping with each other, wherein each heat exchange row comprises a first distributor and a second distributor and a plurality of parallel, coplanar tubes interconnecting the first distributor and the second distributor,
  • the heat exchanger 1 is a heat transfer fluid/air heat exchanger, in particular an inner condenser of a heat pump HVAC system for an electric vehicle.
  • An example of this system is shown in Fig. 16 .
  • IC denotes an inner condenser with which a fan B is associated, which fan is provided for supplying heated air to the interior of the passenger compartment of the vehicle.
