Heat spreader

A mobile device, comprising:

• an electronic component as a heat source;
• and
• a heat conductive sheet, comprising:
• a first folded section and a second folded section, each having at least two folds of the sheet establishing at least three superimposed layers of the sheet between the folds, wherein the folded section conducts heat from the heat source, wherein the folded section further includes a solid core, and wherein the sheet of the folded section is configured around the solid core;
• two layers of the heat conductive sheet, other than that of the three superimposed layers, wherein the two layers of the heat conductive sheet extend beyond an end of the first and second folded sections and spread heat across the mobile device and towards an exterior of the mobile device, and wherein the two layers of the heat conductive sheet receive the heat from the folded section.

A manufacturing method, comprising:

• configuring a heat conductive sheet on a heat source of an electrical device so that the heat conductive sheet comprises:
• a folded section having at least two folds of the sheet establishing at least three superimposed layers of the sheet between the folds, wherein the folded section conducts heat from the heat source, wherein the folded section further includes a solid core, and wherein the sheet of the folded section encircles the solid core;
• a layer of the heat conductive sheet, other than that of the three superimposed layers, wherein the layer of the heat conductive sheet extends beyond an end of the folded section and spreads heat across the electrical device and towards an exterior of the electrical device, and wherein the layer of the heat conductive sheet receives the heat from the folded section;
• wherein the superimposed layers are closer to the heat source than the layer of the heat conductive sheet.
