Abstract
The heat sink has an interior and has a first exterior surface and a second exterior surface, and includes a first heat removal region disposed in the interior. The first heat removal region defines a first cavity and is at least partially filled with a liquid. The first heat removal region transfers a first amount of heat from a first electronic device via a pool boiling phenomenon when the first electronic device is disposed on the first exterior surface. A first conduction-inhibiting region is disposed proximate the first cavity. A second heat removal region is disposed in the interior. The second heat removal region defines a second cavity and is at least partially filled with the liquid. The second heat removal region transfers a second amount of heat from a second electronic device via the pool boiling phenomenon when the second electronic device is disposed on the first exterior surface.
