A heat transfer device includes a storage chamber, a coolant housed within the storage chamber, a cooling chamber, one or more heat transfer components, a fluid passage between the storage chamber and the cooling chamber, and a barrier element. The one or more heat transfer components facilitate heat transfer from a heat source outside of the cooling chamber to the cooling chamber. The barrier element may have (i) a closed configuration, and (ii) an open configuration in which the barrier element is configured to allow the coolant in the storage chamber to flow from the storage chamber into the cooling chamber. The barrier element may reconfigure from the closed configuration to the open configuration in response to a trigger condition, such as the coolant housed within the storage chamber reaching a trigger temperature and/or the initial pressure of the coolant housed within the storage chamber reaching a trigger pressure.

Fluid apparatus and related methods are disclosed. An example fluid apparatus includes a body defining a fluid flow path between an inlet and an outlet. A flow control member is positioned in the fluid flow path. The flow control member has a base pivotally coupled to an inner wall of the body defining the fluid flow path. The flow control member has an annular tip that is to flex between an open position to allow fluid flow through the fluid flow path and a closed position to prevent fluid flow through the fluid flow path.

Heat transfer devices include a first disc, a second disc positioned adjacent to the first disc, and at least one spacer positioned between the first disc and the second disc.

The pin cooling structure comprises a distal end configured to facilitate heat exchange between the pin cooling structure and an external/adjacent/separate body and one or more side walls. At least one of the one or more side walls, the distal end, and the aperture at least partially define a pin volume. The second disc defines an inlet that is configured to (i) receive a fluid, and (ii) allow the fluid to flow from the inlet and into the pin volume.

Embodiments of the present disclosure generally relate to heat transferring apparatuses and methods. The apparatus and methods utilize the Joule-Thomson effect to remove heat from a heat source to facilitate cooling of the heat source. In one example, an apparatus receives heat from an object to be cooled. The received heat is used to pressurize a fluid. The pressurized fluid is depressurized through a venturi using vapor pressure as a driving force, thus cooling the fluid.

A method, for providing spatial stability and electrical power with a hybrid power source and control moment gyroscope (HPCMG), includes producing spatial stability force for the HPCMG by spinning a central mass within a first transverse gimbal assembly about a first axis of rotation of a control moment gyroscope (CMG). The CMG includes the first transverse gimbal assembly, the central mass, and a second gimbal assembly rotationally connected to the first transverse gimbal assembly. The first transverse gimbal assembly is rotationally connected to the central mass at a first position of the first transverse gimbal assembly and at a second position of the first transverse gimbal assembly along the first axis of rotation. The method includes producing a voltage potential with the central mass. The method includes charging or discharging the central mass through conductive bearings.

Heat transfer devices and methods for enclosing a heat source and facilitating convective heat transfer from the heat source. A heat transfer device includes an outer wall having an outer surface exposed to an environment of the heat transfer device and defining an outer shape of the heat transfer device, and an inner wall defining a flow passage through the heat transfer device. The outer wall and the inner wall collectively define an internal volume that is configured to house the heat source. The flow passage includes an inlet configured to receive a fluid from the environment, and an outlet configured to exhaust the fluid from the flow passage that includes a core region extending between the inlet and the outlet and configured to deliver the fluid from the inlet to the outlet and allow heat to exchange between the fluid within the core region and the internal volume.

Guide vane check valve assemblies and poppets for guide vane check valve assemblies are disclosed. A guide vane poppet includes an elongate central core configured to form a fluid seal with a valve body of the check valve assembly. The guide vane poppet additionally includes an elongate outer skirt and at least one guide vane radially extending between the elongate central core and the elongate outer skirt.

Example implementations relate to Additive Manufacturing (AM) pressurization diffusers. An example diffuser includes an integral component configurable for receiving and diffusing pressurant. Particularly, the integral component includes multiple elements manufactured as a single-piece structure, including an inner filter, outer shell, and flange. The inner filter includes micro-diamond holes that enable pressurant received at an opening of the inner filter to diffuse out of the inner filter and subsequently through holes positioned in a shell surface of the outer shell. The flange can position the diffuser such that the opening of the inner filter is in pressurant communication with a pressurant source (e.g., opening of a tank) enabling the diffuser to receive and diffuse pressurant in a predefined pattern. For example, when the diffuser is positioned inside a tank, the diffuser can have a frustum configuration that helps diffuse pressurant upwards towards inner sidewalls of a pressure vessel, tube or channel.
