Abstract: A heat-management device includes an array of recesses distributed across an external surface of a thermally conductive body. The device includes an array of protrusions interspersed with the array of recesses that form a network of cavities within an internal volume of the thermally conductive body. The array of recesses and the array of protrusions define a non-planar interface that is complementary to a curved surface of a heat source. A fluid volume can be retained within the network of cavities at a pressure lower than atmospheric pressure. The heat management device includes a cooling operation mode wherein the fluid volume absorbs heat from the heat source through the non-planar interface and dissipates heat away from the heat source through the network of cavities.

Abstract: A lost wax cast vapor chamber device is provided. Once a mesh is produced, a meltable core is formed from a meltable core material with the mesh positioned at least partially inside the core. Over the meltable core a metallic layer is formed, at least partially surrounding the meltable core. A chamber formed by the metallic layer is exposed by melting the meltable core to cause it to be removed from an internal void of the chamber, the internal void encapsulating the mesh. The melted material from the meltable core flows out an opening on at least one surface of the chamber. Subsequently, the internal void is filled at least partially with a working fluid and the opening is closed. The mesh supports the surfaces of the chamber against deformation under the vacuum of the internal void. Movement of working fluid by capillary action is facilitated by the mesh.
