Abstract

A heat exchanger includes a central body with a first set of channels and a second set of channels extending along a main direction through the central body, wherein, in the central body, in any cross-section across the main direction, the channels of the first and second sets form a checkered pattern in said cross-sections, wherein the heat exchanger further includes two inner transition portions, wherein, in respective inner transition portion, among the rows extending along a first direction, are every second, counted along a second direction, row provided with channels being along the main direction increasingly shifted in position in a first direction relative to the other channels such that the checkered pattern of channels is transformed into a line pattern.
