A multi-fluid heat exchanger having separate fluid flow paths for two fluid streams to be heated or cooled by a third fluid stream includes first and second elongated, parallel tubular headers ( 10, 12 ), having opposed ends ( 14 ), generally uniformly spaced elongated tube slots ( 16 ) in each of the headers ( 10, 12 ) with the tube slots ( 16 ) in one header ( 10 ) facing-and aligned with the tube slots ( 16 ) and the other header ( 12 ), a plurality of flattened tubes ( 20 ) extending between the headers ( 10, 12 ) and having ends ( 22 ) received in aligned ones of the tube slots ( 16 ), one tube slot ( 24 ) in each header being unoccupied by any of the flattened tubes ( 20 ), the one tube slots ( 24 ) being aligned with each other and located at a predetermined location between the ends ( 14 ) of the headers ( 10, 12 ) and between two groups (A, B) of the flattened tubes ( 20 ) so there are two groups of the flattened tubes ( 20 ) on each side of the one tube slot ( 24 ), a pair of baffles ( 30 ) in each header ( 10, 12 ) with one on each side of the one tube slot ( 24 ) and fins ( 26, 32 ) extend between and are in heat transfer relation with at least the adjacent tubes ( 20 ) in each of the groups (A, B).
