Definitions
- the present invention relates to a method of producing a tubular device comprising an internally finned inner or liner tube, and a smooth outer or shroud tube in radial pressure contact with the inner or liner tube.
- It is an object of the present invention to provide a method of producing a composite tubular device comprising an internally finned liner tube formed of a first metal, and a smooth shroud tube having its inner surface in continuous radially acting pressure contact with the outer surface of the liner tube.
- It is a further object of the present invention to provide a novel method of producing a composite tubular device which comprises extruding a liner tube provided with internal longitudinally extending fins and a smooth outer surface, assembling the liner tube in an outer shroud tube having an internal diameter slightly greater than the outside diameter of the liner tube, the shroud tube having smooth inner and outer surfaces and having a yield strength substantially less than the yield strength of the liner tube, reducing the diameter of the shroud tube sufficiently to materially stress the liner tube so as to produce continuous radially acting pressure contact between the outer surface of the liner tube and the inner surface of the shroud tube.
- FIGURE 1 is an end view of the composite tubular device.
- FIGURE 2 is an end view of the inner liner tube prior to assembly.
- FIGURE 3 is an enlarged fragmentary sectional view of the inner liner tube.
- the tubular device indicated generally at 10 in FIG- URE 1 comprises an inner tube 12 provided with a multiplicity of generally radially inwardly extending fins 14 which are tapered as best illustrated in FIGURE 3.
- the outer surface of the tubular device be of a metal other than aluminum and copper has been found to be entirely satisfactory for this purpose, due in part to its resistance to corrosion.
- the inner tube 12 is inser-ted into an outer or shroud tube 16 formed of a corrosion resistant material, preferably copper.
- a corrosion resistant material preferably copper.
- Excellent results are obtained when the shroud tube is formed of DHP copper.
- the copper tube is formed with an internal diameter sufficiently greater than the external diameter of the extruded aluminum tube so as to permit ready assembly. Excellent results are obtained when the aluminum liner tube is extruded to have an outside diameter of 0.680/ 0.690.
- the copper shroud tube, which is initially formed to fit loosely over the inner liner tube is produced with an outside diameter of 0.790/ 0.800", and with a wall thickness of 0.036".
- the yield strength of the inner tube must be substantially greater than that of the shroud tube.
- the minimum yield strength of the copper shroud tube is approximately 6,000 p.s.i.
- the yield strength of the aluminum liner tube, after the age hardening thereof, is approximately 16,000 p.s.i.
- the assembly After loosely assembling the aluminum liner in the copper tube, the assembly is pulled through a die having an aperture of 0.750". This operation creates an intimate pressure contact between the outside diameter of the liner and the inside diameter of the copper shroud tube which provides a low resistance thermal conductive path.
- the aluminum liner tube is aged subsequent to sinking and before assembly with the copper shroud tube.
- the copper tube is subjected to an 8% reduction in cross-sectional area by the draw operation.
- the composite tubular device described in the foregoing is particularly useful as a water chiller tube because the inner surface of the liner is provided with fins which produce a total inside area of contact approximately twice as great as the outside area. Since the outside of the tube is in contact with water and the inner surface of the tubular device is in contact with a chilled gaseous medium, this area ratio produces a highly eiiicient overall heat transfer relationship.
- the eflicient tubular device permits the formation of the internally finned'structure by highly eflicient extrusion of a material designed for this purpose, while at the same time, it is characterized by the external corrosion resisting surface of a dissimilar metal, specifically copper, to be assembled together by an operation which insures a permanent radially acting pressure between the smooth adjacent surfaces of the shroud and liner, thus producing a thermal conductive path of low resistance.
- a composite tubular device which comprises eftruding a liner tube having a smooth outer surface and 'a'finned inner surface, assembling over said liner tube a shroud tubehaving smooth inner and outer surfaces and having a yield strength substantially less than the yield strength of the liner tube, sinking the shroud tube onto the liner tube by drawing the assembly through a die sized to materially stress the liner tube.
