Abstract: A heat exchanger is provided that can include furcating unit cells coupled with each other. Each of the unit cells can be elongated along an axis and include a sidewall that defines annular ring openings on opposite ends of the unit cell along the axis. The sidewall also can define undulating annular rings between the annular ring openings and axially separated from each other along the axis. The sidewall can further define angled openings into the unit cell both above and below each of the undulating annular rings. At least a first opening of the annular ring openings and the angled openings can be configured to be an inlet to receive a first fluid into the unit cell and at least a second opening of the annular ring openings and the angled openings configured to be an outlet through which the first fluid exits the unit cell.

Abstract: A multi-domain cooling assembly configured to be coupled with one or more heat sources includes a body having an outer surface and at least one cooling chamber disposed inside the body. The at least one cooling chamber extends in at least two orthogonal dimensions and includes a working fluid to extract thermal energy from the one or more heat sources. The assembly includes a cooling channel disposed within the body and fluidly coupled with a passageway that carries cooling fluid into and out of the cooling channel. At least a portion of the cooling fluid is a liquid phase, a gas phase, or a liquid-gas mix phase. The cooling channel is fluidly separate from the at least one cooling chamber. The cooling channel is thermally coupled with the at least one cooling chamber. The at least one cooling chamber transfers thermal energy from the working fluid to the cooling fluid.

Abstract: A tip for a turbine component, turbine rotor blade or tip of a blade, is disclosed. The tip includes a tip plate configured to be coupled at a tip end of an airfoil chamber; and a tip rail extending radially from the tip plate, the tip rail disposed near or at a periphery of the tip plate. The trip rail includes a cooling structure constituting at least a portion of the tip rail. The cooling structure is in fluid communication with the airfoil chamber, and includes a plurality of repeating, three dimensional unit cells. Each unit cell defines a flow passage that is in fluid communication with the flow passage of at least one other unit cell. The flow passages of the 3D unit cells create a tortuous cooling passage in at least a portion of the tip rail.
