Heat dissipating device and heat dissipating fin

Abstract

A heat dissipating device includes a heat dissipating fin and a heat pipe. The heat dissipating fin includes a fin body, a through hole, a first arc-shaped portion and a second arc-shaped portion. The through hole is formed on the fin body and has a central line. The first arc-shaped portion extends from the through hole in a first direction and the second arc-shaped portion extends from the through hole in a second direction, wherein the first direction is opposite to the second direction. The first arc-shaped portion and the second arc-shaped portion are located at opposite sides of the central line. The heat pipe is disposed in the through hole.

What is claimed is: 
     
         1 . A heat dissipating device comprising:
 a heat dissipating fin comprising a fin body, a through hole, a first arc-shaped portion and a second arc-shaped portion, the through hole being formed on the fin body and having a central line, the first arc-shaped portion extending from the through hole in a first direction, the second arc-shaped portion extending from the through hole in a second direction, the first direction being opposite to the second direction, the first arc-shaped portion and the second arc-shaped portion being located at opposite sides of the central line; and   a heat pipe disposed in the through hole.   
     
     
         2 . The heat dissipating device of  claim 1 , wherein a radian of the first arc-shaped portion and a radian of the second arc-shaped portion both are between 15 degrees and 345 degrees. 
     
     
         3 . The heat dissipating device of  claim 1 , wherein the first arc-shaped portion and the second arc-shaped portion are symmetrically located at opposite sides of the central line. 
     
     
         4 . The heat dissipating device of  claim 1 , further comprising a base, the heat dissipating fin being disposed on the base, the heat pipe having a heat dissipating end and a heat absorbing end, the heat dissipating end being opposite to the heat absorbing end, the heat dissipating end being disposed in the through hole, the heat absorbing end being fixed on the base. 
     
     
         5 . A heat dissipating fin comprising:
 a fin body;   a through hole formed on the fin body and having a central line;   a first arc-shaped portion extending from the through hole in a first direction; and   a second arc-shaped portion extending from the through hole in a second direction, the first direction being opposite to the second direction, the first arc-shaped portion and the second arc-shaped portion being located at opposite sides of the central line.   
     
     
         6 . The heat dissipating fin of  claim 5 , wherein a radian of the first arc-shaped portion and a radian of the second arc-shaped portion both are between 15 degrees and 345 degrees. 
     
     
         7 . The heat dissipating fin of  claim 5 , wherein the first arc-shaped portion and the second arc-shaped portion are symmetrically located at opposite sides of the central line.
