Abstract

Abstract A personal computer including a bottomed case, a keyboard, a top cover forming with said keyboard, an upper face covering said bottomed case, and a heat dissipation structure disposed between the upper face and the bottomed case. The heat dissipation structure includes a printed circuit board having a current consuming device mounted thereon, a first heat dissipation plate disposed under the keyboard, and a first heat conductive block coupled to the first heat dissipation plate and the printed circuit board. The heat conductive block conducts heat generated by the current consuming device to the first heat dissipation plate. The heat dissipation structure further includes a second heat dissipation plate disposed on the bottomed case, and a second heat conductive block coupled to the second heat dissipation plate and the printed board, wherein the second heat conductive block conducts the heat generated by the current consuming device to the second heat dissipation plate.
