Abstract
A heat sink assembly (100) for cooling a heat-generating electronic component, includes a base plate (32), a plurality of fins (50) mounted on the base plate and a heat pipe (20) thermally connecting the base plate and the fins. The fins are parallel to the base plate and include a bottom fin (40) supporting the fins on the base plate. The bottom fin includes a plurality of supporting tabs (422) engaging with the base plate and separating a body (42) of the bottom fin from the base plate. The bottom fin can be used not only for dissipating heat into a surrounding environment but also for reinforcing the whole strength of the heat sink assembly.
Claims16
A heat sink assembly comprising:
- a base plate for absorbing heat generated by a heat-generating electronic component;
- a plurality of parallel fins mounted on and thermally connecting with the base plate for dissipating heat from the base plate, said fins comprising a bottom fin having a body parallel to the base plate and a plurality of supporting tabs extending downwardly from the body;
- and
- a heat pipe thermally connecting the base plate and the fins;
- wherein the supporting tabs engage with a top surface of the base plate to support the fins onto the base plate and reinforce a whole strength of the heat sink assembly.
A heat sink assembly adapted for dissipating heat generated by a heat-generated electronic component, the heat sink assembly comprising:
- a base plate;
- a plurality of fins mounted on and thermally connecting with the base plate, each of the fins parallel to a top surface of the base plate;
- a supporting bracket mounted between the base plate and the fins for supporting the fins on the base plate, the supporting bracket comprising a flat body and a plurality of supporting tabs engaging with the top surface of the base plate, the supporting tabs separating the body of the supporting bracket and the base plate;
- and
- a heat pipe comprising an evaporating portion engaging with the base plate and at least a condensing portion extending through the fins and the supporting bracket and thermally connecting therewith.
A heat sink assembly comprising:
- a base plate for thermally connecting with a heat-generating electronic component;
- a plurality of fins parallel to the base plate and located above the base plate, wherein a bottom one of the fins having at least a tab extending downwardly to engage with the base plate, thereby reinforcing connection strength between the fins and the base plate;
- and
- at least a heat pipe having an evaporating portion thermally engaging with the base plate and a condensing portion extending through the fins and thermally connecting therewith whereby heat of the base plate absorbed from the heat-generating electronic component is transferred to the fins via the heat pipe to be dissipated to ambient air.
