  • Publication number: 20090042049
    Abstract: A projection weld element can include structure that prevents gases or other contaminants from passing through or around the weld element before, during or after attachment to a workpiece such as a vehicle body part. The projection weld element can include a barrel having a first axial end and a second axial end, a central axial bore being defined through the barrel from the first axial end towards the second axial end, and at least a portion of the central axial bore including an attachment structure, such as internal threads. A radial flange can extend from the second axial end of the barrel, with the flange including a distal axial face on a side of the flange facing away from the first axial end of the barrel and a proximal axial face on a side of the flange facing toward the first axial end of the barrel. The flange can include an annular projection weld ring formed along the proximal axial face of the flange on the same side of the flange as the barrel that extends from the flange.

  • Patent number: 7278209
    Abstract: A method for manufacturing a heat sink for use in a heat sink fan is provided. A heat-sink base portion defining a central axis and a circumferential surface is formed. A plurality of heat-radiating fins is formed on the circumferential surface of the base portion. Each of the heat radiating fins extends away from the central axis and defines at least one radially distal edge. After the base portion and the heat-radiating fins are formed, a distal-edge protrusion or a recess is formed on or in at least one of the heat radiating fins by a machining process, so as to form partially along the envelope of the heat sink at least one discrete engagement feature.
