These devices are known to have inlets for a refrigerant, a distribution pipe to distribute the refrigerant to a plurality of flat tubes, a manifold to collect the refrigerant after passing through the flat tubes, and a drain. It is possible to fill the collecting and distribution pipes in the form of a water box that has a partition. It must be ensured, however, that the partition wall tightly separates the water box into an input and an output section.
