Thermal dissipation in dual-chassis devices

A converged mobility device, comprising:

• a first chassis comprising a first touch screen and primary processing elements of the converged mobility device, the first chassis having a first slit aperture;
• a second chassis comprising a second touch screen, the second chassis coupled to the first chassis via a spring-loaded guide hinge having a pip and a cylindrical guide, the second chassis lacking primary processing elements of the converged mobility device whereby the second chassis generates substantially less heat than the first chassis, the second chassis having a second slit aperture at a near end to the first slit aperture of the first chassis;
• a heat spreader passed through the first slit aperture and the second slit aperture, and comprising a flexible graphite sheet passed over the pip and around the cylindrical guide;
• and
• a spring-loaded guide, wherein the flexible graphite sheet passes over the spring-loaded guide and the spring-loaded guide extends and retracts a length of the flexible graphite sheet in the second chassis as the second chassis is rotated relative to the first chassis.
