Disclosed is a foldable graphite heat spreader for reducing the internal temperature of an electronic device. The foldable graphite heat spreader includes a multi-layer graphite lamination having a top surface, a bottom surface and a corrugated surface along the bending areas of the electronic device. The multi-layer graphite lamination spreads heat on the hot spots or takes heat away the components of the electronic device. The top surface includes a first top end and a second top end. The bottom surface includes a first bottom end and a second bottom end. The corrugated surface includes a top corrugated surface and a bottom corrugated surface and have spring characteristic to expand when bending, to contract back its original shape when no bending. The foldable graphite heat spreader includes a protective plastic film for providing protection to the top surface and the top corrugated surface of the multi-layer graphite lamination from dropping particles of graphite. The protective plastic film provides protection to the bottom corrugated surface and at least a portion of the bottom surface at bending location graphite without damage from bending operation. Further, the foldable graphite heat spreader includes a pressure sensitive adhesive attached to the heat-generating surface of the electronic device.
