Heat exchanger, method for forming thereof and use thereof

A heat exchanger, comprising:

• a central body that is hollow which is received in a housing and defines an inner channel for a first medium, wherein a space surrounding the central body in the housing defines at least one outer channel for a second medium, wherein the central body has on either side parts protruding from a main plane thereof and the central body comprises at least two substantially parallel profiled plates connected locally to each other, wherein the parts protruding from the main plane of the central body are connected to mutually opposite parts of the housing, wherein the protruding parts bound the outer channel, wherein the outer channel has a meandering form substantially parallel to the main plane of the central body, the meandering form defining a flow path for the second medium that alternates between first and second flow directions for the second medium that are transverse to a direction of flow of the first medium and directly opposite one another, wherein an outlet for the first medium and an inlet for the second medium share a first side of the central body and wherein an inlet for the first medium and an outlet for the second medium share a second side of the hollow central body.
