Abstract: A head-mounted device includes a housing configured to be worn on a head of a user. The housing includes an inlet port and an outlet port. An air circulation device is mounted to the housing and configured to produce a flow of air through an air flow path in the housing that extends from the inlet port to the outlet port. A display assembly is mounted to the housing and has a surface in the air flow path of the housing. An air deflector mounted to the surface of the display assembly and configured to reduce a turbulence of the flow of air through the air flow path.

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-mounted device may have a head-mounted housing. The housing may include a chassis with left and right openings that overlap respective left and right optical modules that present images eye boxes. Each optical module may have a lens and display that presents an image through the lens. The chassis may have an inner frame and outer frame. A middle portion of the chassis may form a stiffened nose bridge structure. Components in the housing such as a display, a fan housing, a heat sink layer, optical module guide rods, and a rear cover may span the width of the housing and may be attached to edge portions of the chassis, thereby forming a box-shaped structure that provides rigidity and helps prevent housing deformation.

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 head-mounted device can effectively manage heat while also managing noise output levels in a manner that preserves the user's desired experience with the head-mounted device. The head-mounted device can manage sound levels of a cooling system based on detected a sound level of ambient noise in a vicinity of the head-mounted device. For example, the head-mounted device can operate a fan at a speed that produces noise at a sound level that is low enough to be masked by the ambient noise perceived by the user. By further example, the sound level of a cooling system can be based on a sound level of a speaker of the head-mounted device providing audio to the user. By further example, other operational parameters of a cooling system can be controlled to manage noise at a sound level that is sufficiently low.

Abstract: A head-mounted display to be worn by a user includes a housing, a component chamber defined in the housing, and electronic components that generate heat. The electronic components are located in the component chamber of the housing. The head-mounted display also includes a first fan for causing air to flow through the component chamber.
