Abstract
This document describes a thermal-control system that is integrated into a media-streaming device. The thermal-control system includes a combination of heat spreaders and materials with high thermal-conductivity. The thermal-control system may spread, transfer, and dissipate energy from a thermal-loading condition effectuated upon the media-streaming device to concurrently maintain temperatures of multiple thermal zones on or within the media-streaming device at or below multiple respective prescribed temperature thresholds.

A thermal-control system for a media-streaming device, the thermal-control system comprising:
- a first thermal-control subsystem comprising:
- a first graphite sheet, the first graphite sheet fixed to a first generally concave interior surface of a first housing component;
- a first heat spreader, the first heat spreader separated from the first graphite sheet by a first air gap;
- and
- a first thermal interface material, the first thermal interface material located between the first heat spreader and a first integrated circuit device mounted to a first surface of a printed circuit board;
- and
- a second thermal-control subsystem comprising:
- a second graphite sheet, the second graphite sheet fixed to a second generally concave interior surface of a second housing component, the second generally concave interior surface of the second housing component facing the first generally concave interior surface of the first housing component;
- a second heat spreader, the second heat spreader separated from the second graphite sheet by a second air gap;
- and
- a second thermal interface material, the second thermal interface material located between the second heat spreader and a second integrated circuit device that is mounted to a second surface of the printed circuit board, the second surface of the printed circuit board opposite the first surface.
A media-streaming device comprising:
- a housing comprising a first housing component and a second housing component joined together;
- a system-on-chip integrated-circuit device mounted to a first surface of a printed circuit board, the printed circuit board positioned within the housing;
- and
- a thermal-control system configured to concurrently maintain temperatures throughout the media-streaming device during a thermal-loading condition, the thermal-control system positioned within the housing and configured to concurrently maintain:
- a first temperature of a first thermal zone at or below a first prescribed temperature threshold, the first thermal zone including the system-on-chip integrated circuit device;
- a second temperature of a second thermal zone at or below a second prescribed temperature threshold, the second thermal zone including a second surface of the printed circuit board that is opposite the first surface of the printed circuit board;
- a third temperature of a third thermal zone at or below a third prescribed temperature threshold, the third thermal zone including a first exterior surface of the first housing component;
- and
- a fourth temperature of a fourth thermal zone at or below a fourth prescribed temperature threshold, the fourth thermal zone including a second exterior surface of the second housing component.
