This makes it possible, in particular, that soldering can also be carried out at locations which are no longer accessible (more) or more difficult due to their position by means of a soldering tool or the like.
- soldering methods or other methods of connection in particular additional methods, such as welding, for example, is also preferred.
- the slot width of the flat tubes is in this case preferably matched to the dividing wall thickness such that, when the two slots overlap, a process-reliable and liquid-tight connection between the flat tube and the dividing wall is created. It can even - especially in extreme cases - caused by the slot overlap of partition and flat tube a sealed cavity to the outside or are generated, which does not adversely affect the process-reliable soldering between the partition and flat tube.
- a heat exchanger according to the invention and in particular an exemplary heat exchanger according to the invention represented by the exemplary embodiment, may in particular be part of a heating system of a motor vehicle or be intended for such.
