Abstract: Wire coils are distributed over the bottom surface of an inner chamber of a vapor chamber. The working fluid of the vapor chamber comprises ferromagnetic particles that are attracted to a wire coil as current passes through the wire coil. The resulting increase in the volumetric concentration of ferromagnetic particles in the vicinity of the activated wire coil increases the capacity of the working fluid to remove heat from an integrated circuit component attached to the vapor chamber in the region of the activated wire coil. The vapor chamber wire coils can be activated based on performance metrics associated with the processor units of an integrated circuit component, thereby allowing for the thermal resistance of the working fluid to be dynamically adjusted based on the workload executing on the integrated circuit component and power consumption transients.

Abstract: In one embodiment, a system includes a chip package and a cooling apparatus coupled to the chip package. The chip package includes one or more processors, and the cooling apparatus includes a first cavity defined at least partially by a first metal wall and a second metal wall and a second cavity defined at least partially by a flat third metal wall and the second metal wall. An internal pressure of the first cavity is lower than an ambient pressure outside the sealed first cavity. The second cavity includes a liquid disposed therein and wick material coupled to an interior surface of the third wall, and the chip package is positioned such that it coupled to the flat third metal wall of the cooling apparatus.
