  • Patent number: 11926810
    Abstract: A bioreactor includes a reservoir container for holding a liquid medium, a duct providing a flowpath in a generally vertical direction upward from the reservoir container, a plurality of fiber assemblies located within the duct, a top of which is higher than a top of the plurality of fiber assemblies, and a circulation system. The upper end of the duct comprises an overflow wall surrounded by a moat, a bottom of which is lower than a top of the overflow wall. The upper end of the duct and moat contact a pocket region that is bounded by a structure that is connected to the duct and that is isolated from fluid communication with an exterior of the pocket region. The liquid medium flows over the overflow wall within the pocket region, contacts gas in the pocket region, overflows into the moat and is removed therefrom by the circulation system.

  • Publication number: 20230171923
    Abstract: A two-phase immersion cooling apparatus may include an immersion tank with a primary condenser in thermal communication with an interior volume of the immersion tank and a vapor management system fluidically connected to the immersion tank. The vapor management system may enable the apparatus to effectively manage periods of high vapor production by removing vapor and other gases from a headspace of the immersion tank, condensing the vapor to liquid, and returning the liquid to the immersion tank.

  • Patent number: 11566215
    Abstract: A bioreactor for culturing of cells is described. Screens suitable as a cell growth scaffold may comprise crossed fibers. Screens may be contained loosely in a screen holder, which in turn may be contained inside a manifold assembly. A lower manifold, screen holder and upper manifold may have identical or similar interior open cross-sections. Flow of liquid medium can occur upwardly through the array of screens, then flowing over a weir in the presence of an air pocket, and into a moat and a pump. The screen holder may have slots whose exterior-facing ligaments are rounded, and may have grooves whose interior-facing edges are rounded. These components may be located inside an incubator suitable to maintain desired environmental conditions and cleanliness.
