Abstract (en)
[origin: EP3336474A1] A heat exchanger comprises a conduit (16) with an interior surface (18) which defines a first flow passage (22). A first plurality of fins (26) project inwardly from the interior surface (18) of the conduit (16). The first plurality of fins (26) are angled relative to a longitudinal axis (X) of the conduit (16) so as to form helical flowpaths (27) for fluid flowing through the first flow passage (22). A second flow passage (24) disposed outwardly of the interior surface (18) and radially outwardly of the first plurality of fins (26).
