Abstract:
A heat sink for an electronic device comprising:a) a seat portion; b) a heat insulation plate extending outwardly from a first side edge of the seat portion; c) a heat conduction plate extending outwardly from a second side edge of the seat portion in the same direction as the heat insulation plate, the heat conduction plate being spaced apart from the heat insulation plate; d) a first heat dispersion plate connected to an end portion of the heat insulation plate by a first folded portion, the first heat dispersion plate located in a space between the spaced apart heat insulation plate and heat conduction plate, such that the first heat dispersion plate is spaced from the heat insulation plate except for a terminal end connected to an inner side of the heat insulation plate; e) a second heat dispersion plate connected to an end portion of the heat conduction plate by a second folded portion, the second heat dispersion plate located in the space between the spaced apart heat insulation plate and heat conduction plate such that the second heat dispersion plate is spaced from the first heat dispersion plate and from the heat conduction plate, except for a terminal end connected to an inner side of the heat conduction plate; f) a first air conduction outlet formed in the first folded portion; g) a first air vent through the first heat dispersion plate adjacent to the connection with the heat insulation plate; h) a second air conduction outlet formed in the second folded portion; and, i) a second air vent through the second heat dispersion plate adjacent to the connection with the heat conduction plate.
