Abstract: An exemplary electronic device with integrated passive and active cooling includes a main logic board, a heat sink, and a cooling fan. A first surface of the heat sink faces the main logic board and contacts a heat-generating component of the main logic board. A second surface of the heat sink faces away from the main logic board and has a recess formed thereon. The heat sink further includes a plurality of fins that surround the recess. The cooling fan is at least partially enclosed within the recess by a fan shroud. The cooling fan is operable to draw air into the recess via channels defined by a first subset of the plurality of fins, and expel air from the recess via channels defined by a second subset of the plurality of fins.

Abstract: An electronic device includes an outer housing having an upper enclosure and a foot coupled thereto, a heat generating component, and a fan assembly integrated into the foot and situated proximate a bottom surface of the heat generating component. The foot can include inlet and outlet vents. The fan assembly can include an inlet, outlet, impeller with blades, shroud and fin stack. The electronic device can also include a heat pipe, a heat transfer stage, a PCB, and a bottom shield. Airflow through the electronic device can be directed across the fin stack, heat pipe, heat transfer stage, and bottom shield. Airflow can occur over a substantially level path through the electronic device from the inlet to outlet vents.
