1. A heat exchanger comprising:
a primary side;
a secondary side;
at least one primary structure on the primary side defining at least one primary space on the primary side; and
at least one secondary structure on the secondary side defining at least one secondary space on the secondary side;
wherein one or more of the at least one primary structure and one or more of the at least one secondary structure delimit a coolant volume separated from the at least one primary space and separated from the at least one secondary space;
wherein one or more of the at least one primary structure and/or one or more of the at least one secondary structure comprises a three dimensional lattice body; and
wherein the heat exchanger further comprises a separation structure providing a fluid tight seal between the at least one primary space on the primary side and the at least one secondary space on the secondary side, and wherein the separation structure is configured to allow coolant of the coolant volume to flow between the primary side and the secondary side.
