Method of making an automotive evaporator |
摘要 |
<p>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. <IMAGE></p> |
