Heat dissipation assembly

Abstract

A heat dissipation assembly includes a heat sink and a fan. The heat sink includes a plurality of fins. The plurality of fins is parallel with each other. Each of the plurality of fins includes two side faces. Each side face is waved. An air channel is located between two adjacent side faces of two adjacent fins. The air channel includes a plurality of wide portions and a plurality of narrow portions interlaced with the plurality of wide portions. The fan is located on a side of the air channel. The fan is adapted to drive air flowing fast in the plurality of narrow portions of the air channel and flowing slow in the plurality of wide portions of the air channel.

1 . A heat dissipation assembly, comprising:
 a heat sink comprising a plurality of fins, the plurality of fins being parallel with each other, each of the plurality of fins comprising two side faces, each side face being wavy, an air channel located between two adjacent side faces of two adjacent fins, the air channel comprising a plurality of wide portions and a plurality of narrow portions; and   a fan located on a side of the air channel, the fan adapted to drive air flowing fast in the plurality of narrow portions of the air channel and flowing slow in the plurality of wide portions of the air channel.   
     
     
         2 . The heat dissipation assembly of  claim 1 , wherein the two side faces of each of the plurality of fins are symmetrical about a central line of corresponding fin. 
     
     
         3 . The heat dissipation assembly of  claim 1 , wherein the plurality of narrow portions is interlaced with the plurality of wide portions.
