Abstract: Some embodiments include a thermal management plane. The thermal management plane may include a top casing comprising a polymer material; a top encapsulation layer disposed on the top casing; a bottom casing comprising a polymer material; a bottom encapsulation layer disposed on the bottom casing; a hermetical seal coupling the bottom casing with the top casing; a wicking layer disposed between the bottom casing and the top casing; and a plurality of spacers disposed between the top casing and the bottom casing within the vacuum core, wherein each of the plurality of spacers have a low thermal conduction. In some embodiments, the thermal management plane has a thickness less than about 200 microns.

Abstract: Some embodiments include a thermal ground plane comprising a first and second casing with folding and non-folding regions. The thermal ground plane may also include a vapor structure and a mesh. The mesh may be disposed on an interior surface of the second casing and the mesh include a plurality of arteries extending substantially parallel with a length of the thermal ground plane. The folding region of the first casing may have an out-of-plane wavy structure. The valleys and peaks of the out-of-plane wavy structure, for example, may extend across a width of the first active region substantially parallel with a width of the thermal ground plane.

Abstract: A phone case with a phone case body and a thermal ground plane is disclosed. The phone case, for example, may include fin that folds, bends, and/or extends outward from the phone case body. The phone case, for example, may include a magnetic area that comprises a toroid or donut shape. The phone case, for example, may include an aperture that extends through the phone case body and/or the thermal ground plane. The thermal ground plane may include a first casing; a liquid transport layer comprising a mesh or an array of pillars; a vapor transport layer comprising a mesh or an array of pillars; and a second casing, an outer periphery of the first casing and an outer periphery of the second casing are sealed together encasing the liquid transport layer, the vapor transport layer, and a heat transfer fluid.

Abstract: A vapor chamber that includes a housing including a first sheet and a second sheet opposing each other and joined together at outer edges of the first sheet and the second sheet and defining a hollow vapor flow pass therein; a working fluid in the housing; a first wick in contact with the vapor flow pass; and a second wick between the first wick and an inner wall surface of at least one of the first sheet and the second sheet. The first wick defines a first liquid flow pass, the second wick defines a second liquid flow pass, and a first average diameter of the first liquid flow pass is smaller than or equal to 75% of a second average diameter of the second liquid flow pass.
