Abstract: A shell and tube heat exchanger includes a tube bundle for passage of a first medium from a first inlet to a first outlet. A second medium flows through a flow space which surrounds the tube bundle. The tube bundle includes first tubes communicating with the first inlet, and second tubes communicating with the first outlet and fluidly connected to the first tubes. The first tubes define an outer enveloping surface which is predominantly adjacent to an enveloping surface of the second tubes. A separating body between the first inlet and a tubesheet which separates the flow space from the first medium prevents the first medium from flowing against the tubesheet and includes inlet tubes which bridge a compensation space between the separating body and the tubesheet and which protrude into the first tubes to direct the first medium into the first tubes while bypassing the tubesheet.

Abstract: A heat exchanger for cooling a gas includes a gas inlet, a gas outlet, and a plurality of cooling tubes arranged between the gas inlet and the gas outlet, wherein the cooling tubes of two successive tube rows are arranged offset transversely to a flow direction of the gas. A fin having openings is provided for receiving a corresponding number of the cooling tubes. The fin has slits arranged at a distance from the openings and configured to follow an edge profile of a honeycomb-shaped hexagon, with the slits of each hexagon surrounding a corresponding one of the openings at the distance. Arranged between adjacent ones of the openings is a corresponding one of the slits at a same distance from each of the adjacent openings, with each slit having an end ending at a deformation point of the fin.
