Abstract: 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.

Abstract: 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.

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.

Abstract: A heat exchanger arrangement, for example for an internal combustion engine, having a brazed radiator block (1) which has flow paths (10) formed from pairs of plates and has flow ducts (3) between the plate pairs (P), wherein in each case at least one plate (11) of each plate pair has a plate elongation (12), and wherein the brazed radiator block is arranged in a housing (2) and, at its circumference, is sealed off with respect to the housing.

Abstract: The present invention relates to a heat exchanger, in particular, an oil cooler for motor vehicles, constructed from trough-shaped heat exchanger plates which are stacked into one another and from turbulence inserts, having two openings for one medium and two further openings for another medium in order to form collecting ducts for the supply and discharge of the media, with flow ducts for the media being formed between the heat exchanger plates. The heat exchanger also includes flow ducts connected to the associated collecting ducts, an upper closure plate which has convexities in the region of the collecting tanks, and an intermediate plate which is provided with holes. The intermediate plate is arranged between the closure plate and the uppermost heat exchanger plate, and one of the holes, formed as a pressure equalizing opening, interacts with the upwardly aligned convexity in the closure plate to improve the internal pressure stability.

Abstract: A heat exchanger according to some embodiments includes heat exchanger plates stacked one inside the other and each having a trough-shaped edge, flow ducts located between the heat exchanger plates for heat-exchanging media, feed ducts and discharge ducts, and an attachment plate having openings for feeding and discharging the media through the attachment plate. In some embodiments, a multipart attachment plate is provided, wherein a bottom heat exchanger plate lies on an attachment plate, and another overlying attachment plate has a cutout having an edge shaped to lie against the trough-shaped edge of the bottom heat exchanger plate.
