Patent ID: 7717165

Claim:
A heat exchanger, comprising: a plurality disks, wherein the plurality of disks includes at least two adjacent disks defining an intermediate space through which a heat exchanger medium or a second medium to be cooled or to be heated can flow, wherein an opening for the second medium is located in an end region of the disks, wherein the opening for the second medium extends essentially over an entire surface of the end region, except for edge regions and regions of the disks in which passages are arranged, wherein heat exchanger medium passages are located in the end region of the disks so that the heat exchanger medium passages are offset in an axial direction of the disks from the opening for the second medium and are located further inward from an end of the disks than the opening for the second medium, wherein at least a portion of the heat exchanger medium passages is located behind at least a portion of the opening for the second medium when a respective disk is viewed in a plane of the respective disk along a longitudinal axis of the respective disk and in a direction extending from an end of the disk where the end region is located to an opposite end of the respective disk, wherein at least another portion of the opening for the second medium is located behind at least another portion of at least one of the heat exchanger medium passages when the respective disk is viewed in the plane of the respective disk in a direction perpendicular to the direction extending from an end of the disk where the end region is located to an opposite end of the respective disk.
