  • Publication number: 20240324152
    Abstract: We describe a power converter cooling arrangement in which a base has a top plate of a thermally conductive material, and a bottom plate and side walls define a chamber. An inlet and outlet are in fluid communication with the chamber, and the chamber is flooded with a cooling fluid that flows between the inlet and outlet. A PCB of a power converter is mounted to, and thermally coupled with, the top plate, where the PCB receives a plurality of power modules (that are used in the power conversion). The base comprises a plurality of fluid channels for flowing cooling fluid therethrough. Each of the fluid channels is arranged to coincide with a location of one or more components mounted to the PCB.

  • Patent number: 12070817
    Abstract: Systems, devices, and methods for additive manufacturing are provided that allow for components being manufactured to be assessed during the printing process. As a result, changes to a print plan can be considered, made, and implemented during the printing process. More particularly, in exemplary embodiments, a spectrometer is operated while a component is being printed to measure one or more parameters associated with one or more layers of the component being printed. The measured parameter(s) are then relied upon to determine if any changes are needed to the way printing is occurring, and if such changes are desirable, the system is able to implement such changes during the printing process. By way of non-limiting examples, printed material in one or more layers may be reheated to alter the printed component, such as to remove defects identified by the spectrometer data.

  • Patent number: 12017405
    Abstract: According to some aspects, techniques are provided for fabricating sinterable metallic parts through the application of directed energy to a build material. In particular, applying energy to a build material comprising a polymer mixed with a metal powder may cause the polymer to form a cohesive structure with the metal powder. As a result, the polymer acts as a “glue” to produce a metallic green part without local melting of the metal. The green part may subsequently be sintered to remove the polymer and produce a fully dense metal part. Optionally, a step of debinding may also be performed prior to, or simultaneously with, sintering.
