A heat exchanger from a stack of plate pairs having fins which are disposed between the plate pairs, and having ducts which vertically extend through the stack, for conveying in and/or conveying out a medium which flows through the plate pairs and which exchanges heat with another medium which flows through the fins, wherein the ducts are formed from openings in the plates and have moldings which extend around opening peripheries, and having a plate, having corresponding openings, which finishes off the stack, wherein a thermally decoupling element, which is inserted either in an integrated or a separate manner and which is incorporated into the vertical duct formation, is disposed between the finishing-off plate and the stack. Such a heat exchanger displays improved resilience to alternating temperature loadings.

Brazed heat exchanger

The disclosure relates to a heat exchanger, for example an indirect air cooler, in which the air, for example compressed charge air for an internal combustion engine, is cooled, for example by a fluid, wherein the heat exchanger is constructed from stacked pairs of plates. The exemplary fluid can be conducted into an inlet region and/or outlet region of the plate pairs in at least one flow path approximately in the direction of the common edge, and further through at least a first duct approximately in cross current with respect to the exemplary air, and passes further through the plate pairs over the largest heat exchange area of the plate pairs approximately in countercurrent with respect to the air, in order to flow through at least one second duct, approximately in cross current with respect to the exemplary air, and back to the outlet.

Heat exchanger

A heat exchanger arrangement in a housing, such as an intake pipe of an internal combustion engine, has at least one stack including tubes and fins and an end plate having media connections, and wherein the stack is inserted into the housing and is fastened therein. A connecting block which contains the media connections and/or at least one profiled rail is arranged on the end plate. The housing has at least one cross-section-expanding wall graduation and/or at least one receptacle integrated into the housing wall, wherein the connecting block sits in the cross-section expansion and/or a cross section of the receptacle corresponds approximately to a cross section of the rail.

Heat exchanger arrangement in a housing

A heat exchanger arrangement, for example for an internal combustion engine, having a brazed radiator block () which has flow paths () formed from pairs of plates and has flow ducts () between the plate pairs (P), wherein in each case at least one plate () of each plate pair has a plate elongation (), and wherein the brazed radiator block is arranged in a housing () and, at its circumference, is sealed off with respect to the housing. To improve the sealing action between the radiator block () and the housing (), it is provided according to the invention that the plate elongations () are formed such that a prescribed dimension of the brazed radiator block () can be set by means of deformation of the plate elongations ().
