Abstract

This specification describes a thermal control system incorporated into a media streaming device. The thermal control system includes a combination of a heat spreader and a high thermal conductivity material. The thermal control system can simultaneously maintain the temperatures of multiple thermal zones on or within the media streaming device at or below corresponding multiple predetermined temperature thresholds by diffusing, transferring, and dissipating energy from thermal load conditions acting on the media streaming device.
