Abstract
A heat exchanger assembly (10) of the tube-fin type comprises a housing (12), a plurality of tubes (24), and a plurality of fins (26). The fins (26) comprise a generally flat plate (27) and have a plurality of holes (28) therethrough. The tubes (24) extend through the holes (28). The fins (26) further include a plurality of undulations (30). The undulations project outwardly from the plate (27) and are arranged in a plurality of engaging rows (32, 34, 36). The undulations (30) are offset between the rows (32, 34, 36) so that the crests (40) of the undulations (30) are not linear in the direction parallel to the width of the plate (27).
Claims17
A heat exchanger assembly (10) of the tube-fin type comprising:
- a housing (12);
- a plurality of fins (26) having a plurality of holes (28) therethrough, a plurality of tubes (24) adapted for disposition within said housing (12) and extending through said holes (28);
- said assembly (10) characterized by said fins (26) including a plurality of undulations (30) arranged in rows (32, 34, 36) between adjacent of said holes (28) and spaced from one another along said rows (32, 34, 36) with the spacing between adjacent undulations (30) varying from one of said rows (32, 34, 36) to the next of said rows (32, 34, 36) and each of said rows (32, 34, 36) including a flat portion (38) of said fin between said undulations (30).
A fin (26) for use in a heat exchanger of the tube-fin type comprising a generally flat plate (27) including a plurality of holes (28) therethrough for supporting a plurality of tubes (24), and characterized by including a plurality of undulations (30) arranged in rows (32, 34, 36) between adjacent of said holes (28) and spaced from one another along said rows (32, 34, 36) with the spacing varying from one of said rows (32, 34, 36) to the next of said rows (32, 34, 36) and each said rows (32, 34, 36) including a flat portion (38) of said fin (26) between said undulations (30).
