A heat dissipation device for the central processing unit (CPU) with larger area mainly comprises a finned plate and a board member mounted to the finned plate. The finned plate includes a plurality of rows and/or columns of fins extending upwardly from an upper side, wherein gaps are formed among every adjacent fins for the purpose of air circulation, and two separable grooves are defined among every adjacent fin block. The board member includes a hole, and a support member provided in the hole and connected to the periphery defining the hole by a plurality of ribs extending to the support member. A stud is formed on an upper side of the support member and includes a second hole defined therein for rotationally receiving a rotor shaft of fan. At lease one holder is provided at the grooves for mounting the heat dissipation device onto the central processing unit. |
