Abstract:
1. A heat exchanger, comprising: a package of plane-parallel plates; hot medium flow regions and cooling medium flow regions in an alternating arrangement between respective pairs of said plates and lying on top of one another; and hot medium and cooling medium flow regions in an alternating arrangement between respective pairs of said plates and lying on top of one another; and hot medium and cooling medium profile strips laterally bordering said hot medium flow regions and said cooling medium flow regions, respectively, and maintaining adjacent plates at a distance relative to one another, said profile strips having solder surfaces adjoining the respective plates, extending along edges of the respective plates and abutting respective ones of on another at angles, each of said cooling medium profile strips having a base body, two legs extending from said base body and a recess between said legs thereof, each said recess having an opening toward and adjacent the respective cooling medium flow region and having an inner end section, starting from each said inner end section each recess having diverging first planar wall parts extending to constrictions of cross sections of said legs thereof, converging second planar wall parts adjoining the respective constrictions and third planar wall parts adjoining the respective second planar wall parts and extending parallel to the respective solder surfaces into a vicinity of said opening of the respective cooling medium profile strip.
