Abstract:
1. A heat dissipating apparatus for removing heat from a heat generating electronic component, the heat dissipating apparatus comprising: a heat spreader for thermally connecting with the heat generating electronic component; a heat sink thermally connected with the heat spreader; and a heat pipe thermally connecting the heat sink with the heat spreader for transferring heat from the heat spreader to the heat sink, the heat pipe comprising an evaporation section attached to the heat spreader, two semicircular condensation sections thermally engaging with the heat sink, and two connecting sections each interconnecting a corresponding condensation section and the evaporation section; wherein the heat sink has a plurality of fins, each fin having a lower part and an upper tab extending upwardly and outwardly from a top of the lower part, a recess being defined around a bottom surface of the upper tab to receive the condensation sections of the heat pipe therein.
