    Abstract: This application relates to a layout of components within an electronic device. The electronic device includes a circuit board and one or more thermal components located on or proximate to each surface of the circuit board. As a result, thermal energy generated by components of the circuit board are drawn away from the circuit board in a more efficient manner. Additionally, the electronic device may include one or more air movers designed to draw ambient air into the electronic device in a manner that causes the ambient air to cool components upstream from the air movers. Further, the electronic device includes a fin stack that is thermally coupled to the aforementioned thermal components, and further receives air driven in by the air mover(s). Also, the electronic device is designed to receive the ambient air through openings that define a 360-degree air inlet.

    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: A portable electronic device is disclosed. The portable electronic device may include a laptop computing device that includes a base portion and a display housing rotationally coupled to the base portion. The base portion includes a fan designed to drive heated air out of the base portion, thus cooling the portable electronic device. A dynamic (movable) air diverter is integrated into the base portion near the fan's outlet. The air diverter is designed to direct airflow from the fan outlet. Moreover, the air diverter can be repositioned by, for example, rotating the display housing relative to the base portion. As a result of the repositioned air diverter, the airflow from the fan outlet is redirected out of the portable electronic device through a different location. The air diverter can be positioned in different discrete locations, or alternatively, can move continuously with the rotational movement of the display housing.

    Abstract: A thermal management system that includes a fan assembly, a heat exchanger, and an insulating box is described. The fan assembly can have two impellers and a housing that includes two scroll portions. An internal portion of the scroll wall can be truncated. A motor housing can be connected to the fan housing via multiple struts. The struts can be oriented angularly with a tangential component and can slope inward to increase the effective inlet area. The heat exchanger can be formed of a fin stack that has a curved body that defines an airflow path that turns radially from the inlet to the exhaust. The heat exchanger can have an inlet that is smaller than the exhaust. The heat exchanger can be connected to one or more heat pipes. The insulating box can have a grid that directs air to certain specific directions.

    Abstract: An accessory to device coupling system can include a first magnet array adapted for assembly with respect to a surface of an electronic device and a second magnet array adapted for assembly with respect to a surface of an accessory device, the accessory device configured to interact electrically with the electronic device. The first magnet array can include a first plurality of magnets arranged in a first pattern of alternating polarities, and the second magnet array can include a second plurality of magnets arranged in a second pattern of alternating polarities that corresponds to the first pattern of alternating polarities. The corresponding alternating polarity patterns can cause the second magnet array to couple to the first magnet array with a normalized attraction force only at an intended orientation and alignment, and with less than half of the normalized attraction force at any other orientation and alignment.

    Abstract: One or more fastenings can be used to fasten components together, such as housing components on a computing device. Each fastening can include a first opening associated with a first component, a second opening associated with a second component, a floating fastener, and a screw. The floating fastener is inserted into the first opening and/or second opening, and includes a threaded opening therein having a primary axis therethrough. The screw is inserted through first and/or second openings and into the threaded opening in the floating fastener. The screw and threaded opening combination is defined by contact between the screw and threaded opening about a thread surface that is substantially perpendicular to the primary axis, a screw thread return angle of 45 degrees or less, and a thread depth that is less than about triple the float between the major diameters of the screw and the threaded opening.
