Latest Patents

Randall Stephenson holds a patent for "Transformer-based power converters with 3D printed microchannel heat sink." This invention focuses on systems and methods that allow for weight and size reduction of electronic components, such as transformer rectifier units (TRUs) or autotransformer rectifier units (ATRUs). The patent describes a fluid cooling system that provides high heat dissipation for transformer assemblies by creating a thermal interface at the windings, which are the hottest spots in such assemblies. The cooling system includes a fluid-cooled winding heat sink element, which may be a thermally conductive bar with microchannels positioned between the core and windings of a transformer. Fluid passes through these microchannels to directly cool the heat-generating windings, enhancing the efficiency of the transformers. Notably, the heat sink element can be produced using additive manufacturing technology.
