A heat sink structure is provided for a rectifier assembly of an air-cooled generator. The heat sink structure comprises a substantially annular base having inner and outer edges. The inner and/or outer edges have (has) a cooling fin arrangement projecting out from the base. The heat sink structure is provided with diode mounts. Each diode mount is adapted to retain a respective diode in a thermally conductive (and preferably press-fit) manner. Heat from each diode is transferred to the base and cooling fin arrangement, to provide a heat sink effect. Also provided is a method of manufacturing a heat sink structure. The method comprises the steps of configuring a sheet of thermally conductive material to include a substantially annular base and radial extensions of the base, and bending the radial extensions so that the radial extensions are substantially perpendicular to the annular base. Perpendicular extensions or prongs thus are defined. A rectifier assembly is provided. The rectifier assembly comprises a substantially annular support, heat sink, and insulator. The insulator is sandwiched between the support and the heat sink structure to electrically insulate the support from the heat sink structure. The support permits air to flow around at least a majority of radially inner edges of the support and the heat sink structure and also around at least a majority of radially outer edges of the support and the heat sink structure. This, in turn, facilitates the transfer of heat from the heat sink structure and the support to the air.
