  • Patent number: 7116021
    Abstract: A charging system includes an alternator body, rotor coil and stator windings. A bridge rectifier is positioned within the alternator body and connected to the stator windings for rectifying the electrical output from the stator windings. The rectifier includes a positive and negative heat sinks each having a top surface and spaced from each other with cooling fins on an outer surface of each heat sink. A plurality of diodes are positioned at each top surface of positive and negative heat sinks. A terminal assembly interconnects respective pairs of positive and negative diodes. At least one pair of interconnected positive and negative diodes are positioned offset from each other at an angle to provide a maximum surface area for the cooling fins.

  • Publication number: 20040263007
    Abstract: A thermal transfer container is disclosed for a semiconductor component to transfer heat to a heat sink such as used in rectifiers for alternators. The thermal transfer container includes an outer cylindrical surface having threads that engage threads defined in the heat sink bore for electrically and thermally connecting the metallic cylindrical container to the heat sink.

  • Publication number: 20040256925
    Abstract: A vehicle alternator includes front and rear housing members, a Y-connected stator coil and rotor supported by the front and rear housing members, and a rear cover that connects to the rear housing member. A brush holder and rectifier are disposed on the rear housing member and interposed between the rear housing member and rear cover. The rectifier is operatively connected to the Y-connected stator coil. The rectifier includes negative and positive heat sinks having pressed fit diodes received within diode openings. Positive and negative heat sinks are less than five millimeters thick, in one aspect of the present invention. A lead frame is formed of an insulator material and mounted on a side of the positive heat sink opposite the negative heat sink. The lead frame includes embedded conductors and connectors that interconnect diode leads of the rectifier diodes in an electrical rectifying configuration.

  • Patent number: 6784576
    Abstract: A rectifier and method for forming the rectifier for an internal alternator regulator (IAR) style alternator includes an integrally formed rectifier body having a ground engaging surface that mounts within the alternator and is grounded through an automotive grounding system. A diode receiving cavity is opposite the ground engaging surface A plurality of negative diodes are secured within the diode receiving cavity and grounded thereto. An insulated conductor substrate is positioned in the diode receiving cavity and has a conductive surface that is insulated from the rectifier body and negative diodes. Positive diodes are secured on the insulated conductive substrate. A terminal connector interconnects negative and positive diodes in a preferred bridge rectifier configuration.
