A heat exchanger ( 1 ) consists of a plurality of disks ( 4 ) which are assembled to form a heat exchanger block or disk stack ( 16 ) and which are formed in each case from sheets ( 22 ) joined together in pairs and enclose between them at least one cavity designed as a duct. The cavity is delimited by the insides of the sheets ( 22 ). In the duct, an internal fluid flows in the longitudinal direction of the disks ( 4 ) and, on the outside of the disks, an external fluid flows transversely to the direction of flow of the internal fluid. Each sheet ( 22 ) has elevations ( 26, 33' ) out of the disk plane, which are formed by material deformation and are directed both into the inside of the disk and toward the outside of the disk, the elevations ( 33' ) directed toward the outside of the disk being configured as elongate stamped-out portions.
