  • Patent number: 11428475
    Abstract: A cooling assembly includes walls extending around and defining an enclosed vapor chamber that holds a working fluid. An interior porous wick structure is disposed inside the chamber and lines interior surfaces of the walls. The wick structure includes pores that hold a liquid phase of the working fluid. The cooling assembly also includes an exterior porous wick structure lining exterior surfaces of the walls outside of the vapor chamber. The exterior wick structure includes pores that hold a liquid phase of a cooling fluid outside the vapor chamber. The interior wick structure holds the liquid working fluid until heat from an external heat source vaporizes the working fluid inside the vapor chamber. The exterior wick structure holds the liquid fluid outside the vapor chamber until heat from inside the vapor chamber vaporizes the liquid cooling fluid in the exterior wick structure for transferring heat away from the heat source.

  • Patent number: 11408682
    Abstract: A shell and tube heat exchanger includes a tube bundle for passage of a first medium from a first inlet to a first outlet. A second medium flows through a flow space which surrounds the tube bundle. The tube bundle includes first tubes communicating with the first inlet, and second tubes communicating with the first outlet and fluidly connected to the first tubes. The first tubes define an outer enveloping surface which is predominantly adjacent to an enveloping surface of the second tubes. A separating body between the first inlet and a tubesheet which separates the flow space from the first medium prevents the first medium from flowing against the tubesheet and includes inlet tubes which bridge a compensation space between the separating body and the tubesheet and which protrude into the first tubes to direct the first medium into the first tubes while bypassing the tubesheet.

  • Patent number: 11397055
    Abstract: A vapor-chamber that includes a porous microstructure sheet with varying surface energy across different regions to optimize utilization of a working fluid. Modulating the surface energy of the porous microstructure sheet can minimize the amount of the working fluid that becomes trapped in the condenser region(s) and maximize an aggregate thin-film evaporation area of the working fluid in the evaporator region(s). The condenser region of the vapor-chamber is treated so that the internal surfaces have low surface energy. For example, the treatment may cause the condenser region to become hydrophobic to minimize the amount of fluid that becomes trapped in the condenser. The evaporator region is treated so that the internal surfaces have high surface energy. For example, the treatment may cause the evaporator region to become hydrophilic to induce the formation of large numbers of robust (e.g., dry-out resistant) thin-film evaporation sites.
