ABSTRACT:
A heat dissipator includes a dissipator body having a flat base adapted to be placed on a CPU and a plurality of fins formed thereon. Air passages are defined between the fins. A holding frame made of a resilient material, such as plastics, is provided, comprising two resiliently deformable securing arms mounted to two opposite sides thereof. Each of the securing arms has a central bore to receive and fix therein a retaining plate which has a lower openings located outside the securing arm to engage a sideways lug formed on a CPU connector on which the CPU is mounted so as to secure the CPU on the connector. A convection fan is integrally incorporated in the holding frame. The retaining plates may be provided with apertures which allow the plastics to fill therein in injection molding the holding frame so as to securely fix the retaining plates within the bores of the securing arms. Leaf springs are provided between the dissipator body and the holding frame to provide a more secure engagement between the retaining plates and the sideways lugs of the connector. Catches are provided on the underside of the holding frame and counterpart members are provided on the dissipator for engagement with the catches and securing the holding frame to the dissipator body.
