1. A heat exchanger comprising:
a shell extending in a longitudinal direction D from a first end to a second end and comprising a mantle extending from the first end to the second end, and
a solid inner core made of a core material and located inside the shell, the core extending in direction D from a first extremity towards the first end to a second extremity towards the second end,
whereby:
at least one first flow path is provided inside the core, each first flow path extending from the first extremity to the second extremity of the core,
n circuitous second flow paths extend through the core and/or between the core and the mantle, so that the at least one first flow path is surrounded by the n second flow paths over a non-zero rectilinear distance ΔL in direction D, n being an integer greater than 1,
whereby each second flow path has an outer wall which:
is formed by the core material when said second flow path extends through the core, and
is formed by combination of the core material and the mantle of the shell when said second flow path extends between the core and the mantle,
whereby each second flow path extends from an inlet at the first extremity of the core to an outlet at the first extremity of the core.
