Abstract
A plate-fin heat exchanger is provided with inlet and outlet headers mounted integrally with the heat exchanger core wherein each header includes a fluid fitting adapted for alignment in an individually selected direction.
Claims19
A heat exchanger, comprising:
- a core formed by a plurality of divider plates arranged in an alternating stack with a plurality of extended surface heat transfer elements to define first and second flow paths for respective passage of first and second working fluids in heat exchange relation with each other, said heat transfer elements being sandwiched between predetermined pairs of said divider plates and cooperating therewith to define said second flow path;
- and
- header means for communicating with the first flow path, said header means being mounted between adjacent pairs of said divider plates in the stack and including a fluid fitting mounted between one of said predetermined pairs of said divider plates and projecting in a selected direction generally away from said divider plates, said one of said predetermined pairs of divider plates sandwiching at least two of said elements in a multiple layer relation.

- an inlet header for communicating the first working fluid to the first flow path, said inlet header being mounted between adjacent pairs of said divider plates in the stack and including an inlet fluid fitting mounted between one of said predetermined pairs of said divider plates and projecting in a selected direction generally away from said divider plates;
- and
- an outlet header for collecting the first fluid flowing from the first flow path, said outlet header being mounted between adjacent pairs of said divider plates in the stack and including an outlet fluid fitting mounted between one of said predetermined pairs of said divider plates and projecting in a selected direction generally away from said divider plates, said one of said predetermined pairs of said divider plates associated with said outlet fluid fitting sandwiching at least two of said second elements in a multiple layer relation.
