Series arranged pipe bundle heat exchanger

Abstract

Abstract 1. Heat exchanger with tube bundles which are arranged in rows and the tubes (2', 2") of wich are offset relative to one another in successive rows and pass through a multiplicity of plate fins (3) and at the same time are connected metallically to the plates, and through which a cooling medium flows and round which a medium to be cooled flows in a cross-current, the medium to be cooled flowing between the plate fins, and there being slits (12) directed transversely relative to the direction of flow of the medium to be cooled, characterized in that these slits (12) in the plate fins (3) are respectively arranged downstream between two tubes (2'), round which the medium to be cooled has already flowed, and upstream of the offset tube (2"), round which the medium to be cooled is to flow, and the edges of the slits (12) are bent over their entire width, that the flow channel formed by two adjacent plate fins (3) is interrupted above the tube, round which the medium to be cooled is to flow, and so that the medium to be cooled is guided round and partially deflected into the adjacent flow channel.
