ABSTRACT:
The slip ring end (SRE) frame is an SRE frame of popular small dimension designed to allow available larger rectifier assemblies having larger heat sinks to be fitted into the SRE frame, thus providing increased heat dissipation capability. Two flattened frame mounting bore wells are provided in an inner cylindrical side wall of the SRE so that larger rectifier assemblies of choice having increased current carrying capability can fit inside the SRE frame. Specially configured rectifier heat sink mounting holes are provided so that the larger rectifier assemblies may be properly and securely mounted in the SRE frame. Additionally, the small SRE frame features strategically placed ventilation apertures of larger dimension to permit greater air flow through the device, thus producing cooler alternator running temperatures and providing higher durability.
