HEAT SINK
First Claim
1. A heat sink comprising:
- a heat dissipation plate forming a channel between each of stages by isolating a plurality of heat dissipating fins in equal intervals and arranging the heat dissipating fins in a multi-stage circle shape, forming a path between the sequentially isolated heat dissipating fins at each of the stages; and
a centrifugal fan alternatively blocking the channel and path at each of the stages through a rotation by a plurality of blades arranged in a multi-stage circle shape to be positioned between the channels, inflowing outer air to discharge the air by generating a pressure difference of inter/outer air through a combination of the blade and the heat dissipation plate.

Abstract
A heat sink provided. In the heat sink in accordance with an embodiment of the present invention, a heat dissipation plate forms a channel between each of stages by isolating a plurality of heat dissipating fins in equal intervals and arranging the heat dissipating fins in a multi-stage circle shape. Then, the heat sink forms a path between the sequentially isolated heat dissipating fins at each of the stages. Also, a centrifugal fan alternatively blocks the channel and path at each of the stages through a rotation by a plurality of blades arranged in a multi-stage circle shape to be positioned between the channels. Then, the centrifugal fan is capable of inflowing outer air to discharge the air by generating a pressure difference of inter/outer air through a combination of the blade and the heat dissipation plate.
