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: Techniques disclosed herein relate to molding inserts with improved cooling performance. A mold insert includes a body and a plurality of heat sink elements coupled to the body. The body includes an area with a recessed surface that has different depths in a plurality of different regions. The plurality of heat sink elements is configured to provide different thermal resistances in the plurality of different regions of the mold insert, where a thermal resistance of the mold insert in a region with a higher recessed surface depth is lower than a thermal resistance of the mold insert in a region with a lower recessed surface depth. In some embodiments, the plurality of heat sink elements form cooling channels that are configured to conduct a cooling fluid from regions of the mold insert with higher recessed surface depths to regions of the mold insert with lower recessed surface depths.

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.
