Abstract
A portable information handling system transfers thermal energy associated with operation of processing components in a main housing portion through a graphite torsion spring formed from a graphite sheet by cutting arms to extend out of opposing corners of a central portion and rolling the central portion about a central axis. The graphite torsion spring passes thermal energy between the housing portions with the spring releasing tension as the housing portions rotate from a closed to an open position and the central axis disposed about a hinge pin that couples the housing portions to each other.
