    Abstract: Fan assemblies are disclosed. Fan assemblies include an impeller with asymmetric design. For example, an impeller may include a first set of blades with one geometry and second set of fan blades with another geometry. This enables a dual-inlet centrifugal fan to generate different air flow performance characteristics for the air entering one fan inlet compared to the air entering the other fan inlet. The impeller, with different fan blade configurations, can better handle air flow entering the fan assembly through different inlets, particularly when the air flow conditions differ through the inlets due to impeding structures (e.g., motor, struts, etc.). As a result, air flow distribution from air leaving the impeller, including the locations associated with the different fan blade configurations, is relatively uniform. Beneficially, when air flow distribution uniformity increases, the fan assembly operates more efficiently, as air flow pressure losses due to flow separation are mitigated.

    Abstract: An electronic device can include a housing that defines an internal volume. The electronic device can also include a component within the internal volume that divides the internal volume into a first volume and a second volume. The first volume and second volume can be fluidically isolated except at an aperture defined by the component. An air-moving system can produce a positive air pressure in the first volume and a negative air pressure in the second volume.

    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.

    Abstract: An electronic device such as a portable computer may be provided with a lower housing and an upper housing. The electronic device may include hinge structures which allow the upper housing to rotate about a rotational axis relative to the lower housing. The electronic device may include a ventilation port structure with intake openings that allow air to be drawn into the electronic device. The ventilation structure may also include exhaust openings that are used to expel air from the lower housing. When the electronic device is in an open position, it may be desirable for the ventilation structure to form more exhaust openings than when the electronic device is in a closed position. The ventilation structure may form lower exhaust openings when the electronic device is in the closed position and form upper and lower exhaust openings when the electronic device is in the open position.
