    摘要: A method of fabricating a condenser tube having a pre-determined tube length and multiple channels including the steps of forming an aperture in a flat strip of metal; moving the flat strip through a plurality of forming operations to fold into an enclosed tube containing channels, which channels include the aperture in their sides and bottoms; and severing the enclosed tube across the aperture to separate the enclosed tube into one condenser tube. The aperture eliminates the need for the channel sides to be severed, hence only the portion of the condenser tube enclosing the channels requires severing. Each pair of apertures is spaced from the next pair of apertures by the pre-determined tube length so that each sever produces one condensing tube of the pre-determined tube length with the apertures being divided into open notches. The invention also includes a heat exchanger utilizing the condenser tube with channel sides containing portions of the apertures.

    摘要: An improved air center form roll for use in combination with a like form roll to produce an accordion-like folded fin for a heat exchanger core, the form roll being of the type comprising a plurality of form discs abutted one to the other and having a plurality of star-like teeth thereabout. Points of the star-like teeth define a major diameter of the form roll and valleys between adjacent ones of the star-like teeth define a minor diameter of the form roll. The form roll further includes at least one stripper disc having no teeth therearound and interposed between at least two of the plurality of form discs wherein the stripper disc has a diameter less than the minor diameter of the form roll. The improvement to the form roll comprises a modified disc having a plurality of modified star-like teeth thereabout. The modified disc is interposed at each abutment between the stripper disc and one of the abutting form discs. The modified disc further having a major diameter defined by points of the modified star-like teeth, the major diameter of the modified disc being smaller than the major diameter of the plurality of form discs.
