    Abstract: A process by which the end (16) of a tube (10) having at least one internal surface feature (12) is reduced and at least a portion of the surface feature eliminated from the tube end while achieving accurate control of the outer diameter of the tube end. The process preferably makes use of a forming tool comprising an external die (24) for reducing the outer diameter of a tube and a mandrel (26) for deforming the internal passage of the tube. The process generally comprises forcing the external die (24) over the end of the tube so that the outer diameter of the tube end is reduced and so that the mandrel (26) is simultaneously inserted through the internal passage of the tube end. While the tube end (16) remains within the external die (24), the mandrel (26) is withdrawn from the internal passage of the tube end to eliminate the internal surface feature (12).

    Abstract: A machine (20) may produce a tube (28) having textured internal and external surfaces (22, 24) in a single operation. Inner (36) and outer knurling tools (42) may form the textured surfaces. The texturing of the internal and external surfaces (22, 24) may be helical patterns of ribs (32) and grooves (30). The height of the ribs (32) formed in the internal and external surfaces (22, 24) may be less than about 35 mils. The angles of the patterns relative to a longitudinal axis of the tube (28) may be less than about 45 DEG . The angle of the helical pattern allows textured tubes (28) to be used as heat exchanger elements wherein flow is directed substantially coaxial to the longitudinal axes of the tubes. The helical pattern formed in the external surface (24) may be oriented in a right hand or left hand helical orientation. Similarly, the helical pattern formed in the internal surface (22) may be oriented in a right hand or left hand orientation.

    Abstract: Process for making micro-multiport tubing for use in automobile air conditioner heat exchangers whereby the tubing is a flat body with a row of side-by-side passageways, which are separated by upright extruded webs. Processing of this tubing involves extrusion, a straightening and cutting operation, assembly and furnace brazing of the condenser. The webs are extruded so that they have a reduced thickness at their centers. In response to successive cold working of the body, the webs are changed in shape to a more uniform thickness state.
