    Abstract: An electronic cooling assembly includes a heat-generating electronic component and a fan. In some examples the fan includes a housing defining an internal volume, the housing thermally coupled to the heat-generating electronic component, and a plurality of blades disposed in the internal volume. In some examples, the fan housing is thermally coupled directly to the heat-generating component via a thermal paste disposed between the heat-generating component and the housing.

    Abstract: An electronic device includes an external frame defining an internal volume, an air inlet port, and an air exhaust port. The electronic device also includes a fan configured to draw air into the internal volume through the inlet port and push air out from the internal volume through the exhaust port, the fan including a housing. The housing defines a fan inlet and a fan outlet and the air inlet port, the fan inlet, the fan outlet, and the air exhaust port define an airflow path with the air inlet port upstream from the fan inlet, the fan inlet upstream from the fan outlet, and the fan outlet upstream from the air exhaust port. The electronic device also includes a display assembly disposed in the internal volume, the airflow path defined between the display assembly and the fan inlet and an internal frame coupled to the external frame, the internal frame disposed between the display assembly and the fan and defining an opening aligned with the fan inlet.

    Abstract: A head-mountable device can provide a cooling module that effectively manages heat while also minimizing noise, vibration, leakage, power consumption, size, and weight. To dissipate heat, the cooling module with a fan can be operated to move air through a chamber within the head-mountable device. An integrated heat sink can provide heat dissipation properties by drawing heat away from heat-generating components and into the chamber. The integrated heat sink can include a base plate that defines at least a portion of the chamber in which the blades of the fan are positioned. The integrated heat sink can further include fins between the chamber and an outlet. The fins can be integrated with the base plate to maximize heat dissipation and reduce the number of interfaces between separate parts.

    Abstract: A cooling system for optimizing fan air flow performance without compromising acoustic performance is disclosed. At least three fan feature embodiments are disclosed: (1) sloped fan blades, (2) sloped impeller hubs, and (3) inlet flow guidance features. For the first embodiment, fan blades attached to an impeller disc and having leading edges that progressively curve toward a center of the impeller disc. For the second embodiment, the impeller disc is attached to and centered on an impeller hub that has a sloped hub surface that progressively curves toward the fan blades. For the third embodiment, an inlet flow guidance feature is positioned within a region surrounding a fan's inlet promoting smooth passage of air into the fan. In some embodiments, all three fan features are combined.

    Abstract: A fan includes an impeller having blades of varying chord lengths. The fan includes a fan housing surrounding the impeller. The fan housing includes a protruding region, or throat, separated from each passing blade by a clearance, or throat gap, that varies according to the chord length. During rotation of the impeller, the impeller blades rotate about a rotational axis, passing the protruding region defining a minimum radial gap to the protruding region. Due to their different chord lengths, the impeller blades pass the throat region at different throat gaps. Shorter blades are likely to have lower amplitude static pressures and lower air velocities resulting at the blade tip, and are hence likely to generate a lower amplitude acoustic pulse at the protruding region. The variety of chord lengths modulate the amplitude of the pressure to spread acoustic sound across multiple frequencies thereby reducing peak amplitude of the acoustic sound.

    Abstract: A fan assembly for a computing device is disclosed. The device can include an impeller having a number of blades and a motor for turning the blades. The motor can turn the blades via a magnetic interaction between the impeller and the motor. A fluid dynamic thrust bearing can be used to control a position of the impeller relative to the motor. In particular, the impeller can be configured to rotate around an axis and the thrust bearing can be used to control movement of the impeller in a direction aligned with the rotational axis. In one embodiment, the thrust bearing can be configured to stabilize the impeller when vibratory forces act upon the fan assembly. More particularly, parameters associated with the thrust bearing can be selected to counteract vibratory forces emitted by a speaker system.
