Claim:
A cooler having a first passageway for directing a cooling medium, at least one second passageway for directing a medium to be cooled comprising a plurality of baffle plates, wherein the baffle plates each have a radially inner region shaped as a conical envelope and a radially outer region shaped as a conical envelope, and a region which runs essentially perpendicular to the axis of the cooler and which has openings for tubes to pass through extends between the radially inner region and the radially outer region, and an essentially axially symmetrical housing which at least partially surrounds the second passageway, wherein the at least one second passageway for directing the medium to be cooled is arranged in such a way that the medium to be cooled, in at least one first region, flows in an essentially axial direction, and the medium to be cooled, in at least one second region, flows in a direction having a radial component.
