Radiating fin

Abstract

A radiating fin includes a main body, on which at least one reinforcing section is formed. The reinforcing section is sunken into a first side of the main body and correspondingly protruded from an opposite second side of the main body. With the reinforcing section formed on the main body, the radiating fin can have largely enhanced structural strength and increased heat-radiating area.

1 . A radiating fin, comprising a main body having at least one reinforcing section provided thereon, and the reinforcing section being sunken into a first side of the main body and correspondingly protruded from an opposite second side of the main body. 
   
   
       2 . The radiating fin as claimed in  claim 1 , wherein the main body is formed along an end thereof with a downward extended first skirt portion and along another end with a downward extended second skirt portion opposite to the first skirt portion. 
   
   
       3 . The radiating fin as claimed in  claim 1 , wherein the reinforcing section creates a recess on the first side of the main body and a corresponding raised area on the second side of the main body. 
   
   
       4 . The radiating fin as claimed in  claim 1  or  3 , wherein the reinforcing section has across-sectional shape selected from the group consisting of a semicircular, a rectangular, and a V-shaped cross section. 
   
   
       5 . The radiating fin as claimed in  claim 1 , wherein the main body has at least one through hole formed thereon. 
   
   
       6 . The radiating fin as claimed in  claim 1 , wherein, in the case of more than one reinforcing section is formed on the main body, the reinforcing sections are regularly arranged on the main body. 
   
   
       7 . The radiating fin as claimed in  claim 1 , wherein, in the case of more than one reinforcing section is formed on the main body, the reinforcing sections are irregularly arranged on the main body. 
   
   
       8 . A thermal module, comprising:
 a base;   a heat pipe including at least one heat absorption section and at least one heat conduction section, and the heat absorption section being associated with the base; and   a radiating fin assembly consisting of a plurality of stacked radiating fins; the heat conduction section being extended through the stacked radiating fins to connect the radiating fins to one another;   and each of the radiating fins having a main body, on which at least one reinforcing section is formed, so that the reinforcing section is sunken into a first side of the main body and correspondingly protruded from an opposite second side of the main body.   
   
   
       9 . The thermal module as claimed in  claim 8 , wherein the reinforcing section has a cross-sectional shape selected from the group consisting of a semicircular, a rectangular, and a V-shaped cross section. 
   
   
       10 . The radiating fin as claimed in  claim 8 , wherein, in the case of having more than one reinforcing section provided on each of the radiating fins, the reinforcing sections can be regularly or irregularly arranged on the main bodies of the radiating fins.
