Abstract: Techniques disclosed herein relate to exploiting photovoltaic effects to improve the thermal management capabilities for wearable electronic devices. In an exemplary embodiment, a wearable electronic device includes photovoltaic cells (102) disposed over a housing assembly (106) that encloses heat-emitting electronic components (108). The photovoltaic cells block solar radiation from reaching an exterior surface of the housing assembly - thereby reducing the solar gain thereof. Electrical energy that is generated by the photovoltaic cells is utilized in some manner that is determined to be currently appropriate based on various current-state factors of the wearable electronic device. For example, the wearable electronic device may include a thermal management engine that modulates the flow of current from the photovoltaic cells based on a current power demand of the wearable electronic device, a current charge level of a battery of the wearable electronic device, and/or a current temperature at one or more sensors of the wearable electronic device.

Abstract: A system for increasing the temperature of a display element includes a heat source configured to perform a user experience function independent of generating heat. The system also includes a thermally conductive element that is coupled to the heat source and is positioned proximate to the display element, forming a thermally conductive path between the heat source and the display element. A method for increasing the temperature of a display element includes generating heat by operating a heat source to perform a user experience function independent of generating heat, and dispersing the heat from the heat source to the display element via a thermally conductive path formed by a thermally conductive element coupled to the heat source and positioned proximate to the display element.

Abstract: Techniques disclosed herein relate to using thermally conductive textiles for heat dissipation from wearable electronic devices. An exemplary thermally conductive textile may be constructed from an elasticated band for encircling a body part of a user (e.g., a user's head) and one or more thermally conductive wires that are affixed to the elasticated band in a wave pattern. The thermally conductive wires being arranged in the wave pattern allows for the thermally conductive wires to freely stretch and contract as forces are exerted on the elasticated band. Thus, the thermally conductive textile described herein exhibit elastic properties that are predominantly governed by the elasticated band while also exhibiting thermal properties that are predominantly governed by the thermally conductive wires. The thermally conductive textiles may also include locking fibers to restrict deformation of the wave pattern of the thermally conductive wires.

Abstract: Devices having multiple layers of paint for enhanced thermal performance. Individual paint-layers have specific properties within specific wavelength-ranges. An exemplary device includes an emissive outer layer that has a high emissivity in a first wavelength-range to increase thermal radiation and a high transmittance in a second wavelength-range to reduce solar gain. Underneath the emissive outer layer is a color matching layer that has a high transmittance in the second wavelength-range and absorbs at least some visible light. Underneath the color matching layer is a reflective sublayer that has a high reflectivity in the second wavelength-range. EM radiation within the second wavelength-range passes through the emissive outer layer and color matching layer before being reflected by the reflective sublayer back into the atmosphere. Thus, solar gain is reduced due to the solar energy within the second wavelength range being reflected off of the device - rather than absorbed as thermal energy.

Abstract: Examples are disclosed herein that relate to fans for cooling systems. One example provides a device including an impingement surface, and a fan positioned to direct a flow of air onto the impingement surface. The fan comprises an impeller and motor assembly, and a housing comprising an inlet end, an outlet end, and a side extending at least partially between the inlet end and the outlet end. The fan further comprises a strut located to position the impeller and motor assembly relative to the housing, and an opening formed in the side of the housing, the opening comprising an upstream edge located farther from the impingement surface than a downstream edge of the housing along an axial direction of the fan.
