  • Patent number: 10302847
    Abstract: In one or more embodiments, micro light guides are constructed that include a wall and one or more features extending from or protruding into one or more surfaces of the wall. The microstructure light guide is defined by a mold and formed as a single article with uniform internal stresses. In at least some embodiments, the mold that defines the microstructure light guide employs pixelated mold portions that enable selective temperature adjustment of discrete regions of the mold portions to form the microstructure light guide.

  • Publication number: 20180164042
    Abstract: A lost wax cast vapor chamber device is provided. Once a mesh is produced, a meltable core is formed from a meltable core material with the mesh positioned at least partially inside the core. Over the meltable core a metallic layer is formed, at least partially surrounding the meltable core. A chamber formed by the metallic layer is exposed by melting the meltable core to cause it to be removed from an internal void of the chamber, the internal void encapsulating the mesh. The melted material from the meltable core flows out an opening on at least one surface of the chamber. Subsequently, the internal void is filled at least partially with a working fluid and the opening is closed. The mesh supports the surfaces of the chamber against deformation under the vacuum of the internal void. Movement of working fluid by capillary action is facilitated by the mesh.

  • Publication number: 20180156545
    Abstract: A three-dimensional printed vapor chamber device is provided. A chamber from a first surface and a second surface at least partially enclosing a volume includes a spanning structure extending from the first surface to the second surface throughout a region within the volume. A defined gap between the first surface and second surface is maintained by the spanning structure, which also defines a plurality of flow passages. Evaporated working fluid flows from an evaporation region proximate a heat source through looped flow passages to a condensation region at a distal end of the chamber before returning as condensate by way of capillary action to the evaporation region.
