Claim of US Patent No. 10,215,496

1. A heat exchanger comprising:a cool heat exchanging conduit adapted for guiding a cool fluid, the cool heat exchanging conduit having a cool fluid inlet and a cool fluid outlet;
a hot heat exchanging conduit adapted for guiding a hot fluid, the hot heat exchanging conduit having a hot fluid inlet and a hot fluid outlet;
a heat exchanging element arranged between the cool heat exchanging conduit and the hot heat exchanging conduit for heat exchange between the cool fluid and the hot fluid;
at least one additional heat exchanging conduit for guiding an additional fluid, the at least one additional heat exchanging conduit having a fluid inlet and a fluid outlet, wherein the at least one additional heat exchanging conduit is arranged adjacent at least one heat exchanging conduit from the group consisting of the cool heat exchanging conduit and the hot heat exchanging conduit, and on a same side of the heat exchanging element as said at least one heat exchanging conduit from the group consisting of the cool heat exchanging conduit and the hot heat exchanging conduit, and wherein the at least one additional heat exchanging conduit is separated from the at least one heat exchanging conduit from the group consisting of the cool heat exchanging conduit and the hot heat exchanging conduit by a separator comprising two separating elements arranged at a distance to each other and forming a cavity between the two separating elements, the separator limiting a fluid flow into or within the cavity the at least one additional heat exchanging conduit and the at least one heat exchanging conduit from the group consisting of the cool heat exchanging conduit and the hot heat exchanging conduit, and arranged on the same side of the heat exchanging element.
