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: A head-mountable device can include an outer frame that can define a first opening, a second opening an internal volume between the first opening and the second opening, an intake port between the first opening and the second opening, and an exhaust port between the first opening and the second opening. In some examples, a front cover assembly can be disposed in the first opening. An inner frame can be coupled to the outer frame, where the inner frame can also define a first aperture and a second aperture. In some examples, a curtain assembly can occlude the second opening. Furthermore, the curtain assembly can include an elastic layer that can define an external surface. The curtain assembly can also include an air-impermeable layer that can define the internal volume.

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 fan motor suitable for use in an electronic device, such as a consumer electronic device, is disclosed. The fan motor includes a stator and a rotor. In order to minimize a varying torque applied to the rotor, the stator includes modifications. For example, the stator includes stator teeth, each with an arc defined by a radius of curvature that varies. The radius (from a reference point to the arc) can vary in accordance with a sinusoidal curve. Furthermore, the corners of each stator tooth may be rounded. The rounded corners of the stator teeth may include a uniform (or constant, non-varying) radius of curvature. These enhancement are designed to provide a more uniform torque by the stator to the rotor. As a result, the rotation of the rotor is subject to smaller fluctuations, and the fan motor undergoes less vibration and generates less acoustical noise.
