Abstract:
1. An electronic device, comprising: a housing; a heat source located inside the housing; and a heat dissipation device disposed inside the housing, the heat dissipation device being in thermal contact with the heat source, the heat dissipation device comprising a casing, the casing having a heat dissipation material, and the heat dissipation material comprising 15 to 30 volume percent of a plurality of copper materials, 50 to 85 volume percent of a phase change material, and 15 to 20 volume percent of air, and a constituent of the phase change material is an alkane; wherein the casing has a surface being in thermal contact with the heat source, a central area and an outer ring area are defined on the surface, the outer ring area surrounds the central area, a geometric midpoint of the central area and a geometric midpoint of the surface are overlapped with each other, the area of the central area is 10% to 50% of the area of the surface, the heat source is located in the central area, and the heat dissipation device absorbs heat generated by the heat source through thermal conduction.
