Abstract: Techniques of managing heat within an electronic device involve providing a vapor chamber in a ring shape within an electronic device. In some implementations, the vapor chamber forms an outer case wall of an enclosure of the electronic device. In further implementations, the vapor chamber has a fill port attached to the inner edge of the vapor chamber. Advantageously, by using a vapor chamber with a ring geometry in an electronic device according to the improved techniques, a form factor of the electronic device (e.g., a laptop, a tablet, etc.) is not affected by the introduction of the vapor chamber as an outer case wall.
