| 1. A heat exchanger, comprising:
tubes which comprise tube ends and through which a first medium can flow in heat-exchange passages and around which a second
medium can flow,
a first collection chamber and a second collection chamber, configured so that the first medium can be passed from said first
collection chamber to said second collection chamber, and
at least one end piece, which comprises a tube plate and a collection box,
wherein said tube plate comprises individual plates bearing against one another, said individual plates including a base plate,
a diverter plate, and a cover plate,
wherein said tube ends are connected to said base plate, and at least one through-passage is formed by a cutout in said diverter
plate and is closed off in a fluid-tight manner with respect to an environment surrounding the heat exchanger by said cover
plate, and
wherein said collection box comprises a housing and at least one collection chamber selected from the group consisting of
said first collection chamber and said second collection chamber, said housing and said cover plate having apertures which
