  • Publication number: 20220348359
    Abstract: Pointing interfaces that can be used to assemble/disassemble instruments/payloads from a spacecraft/host are disclosed. The disclosed interfaces provide structural, communications, power, and fluid connections (for thermal control). Such interfaces also provide active and passive vibration isolation capability for precision pointing.

  • Patent number: 11114713
    Abstract: Thermal management systems for battery cells and methods for their additive manufacture are provided. The thermal management systems include at least one heat pipe that physically contacts the battery cell and conforms to its geometry. Each battery cell is deposited within a separate heat pipe, and each heat pipe is disposed on a base plate, which itself connects to a heat sink. In many embodiments, the heat pipe is a two-phase heat exchanger having three major components: liquid channels, wick elements, and vapor channels. In such embodiments, the wick component comprises a porous body configured to be disposed between the liquid channels and vapor channels. The wick component may be made using a stochastic additive manufacturing process such that the wick component may take any configuration and/or such that the wick component may be directly integrated into the body of the heat pipe as a unitary piece thereof.

  • Publication number: 20200378687
    Abstract: Multi-phase thermal control systems, evaporators, variable porous wick elements, heat transfer structures, and methods for their production are provided. Two-phase evaporators for use in such multi-phase thermal control systems are also provided. Two-phase evaporators incorporate a vapor plate body having there three major layers: a vapor channel network, a wick, and a liquid channel. The vapor channel network comprises a plurality of extrusions (e.g., vapor pillars) and associated channels (e.g., vapor channels) configured to allow a vapor to flow therethrough. The wick comprises a porous body configured to be disposed between the vapor channel network of and the liquid flow reservoir.
