David W. Bertrand - Warren MI

Assignee:

Ford Motor Company - Dearborn MI

International Classification:

B23P 1526

US Classification:

29890039

Abstract:

A method for making a plate-tube heat exchanger 10 is disclosed. The method includes the steps of forming a generally planar plate blank 36 from a deformable sheet of material, forming an aperture 38 at one end of the plate blank and forming a plurality of generally elongate bead preforms 40 in a predetermined configuration by drawing the material from the bottom surface of the plate blank towards the top surface. Next, a plurality of individual beads 34 are formed from each of the plurality of bead preforms by reverse drawing the bead preforms in a direction from the top surface of the plate towards the bottom surface of the plate. The method of the present invention concludes by forming the finish edges 46 of the plate.

Abstract:

A plate-fin heat exchanger 10 is disclosed including a plurality of flat pipes 14 interleaved with a plurality of fin members 16. The flat pipes 14 are formed from a plurality of plate members 12. The heat exchanger 10 also includes a plurality of fin members 16 and a pair of fluid manifolds 22, 24. The manifolds 22, 24 engage the heat exchanger 10 along either of two axes which are perpendicular to the longitudinal axis of the tank 20 of the heat exchanger 10.
