Abstract

A heat dissipating fin including a main body and a through hole is provided. The through hole is formed at the main body. The through hole includes at least two collar portions, and the collar portions are formed on an edge of the through hole. Each of the collar portions includes a first extending portion and a first bridging portion. A first angle is formed between the first extending portion and the first bridging portion. The heat dissipating fin and the heat dissipating device can form a uniform holding force between the heat dissipating fin and the pipe, reduce the damage of the pipe in the assembly, and improve the heat dissipation efficiency.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A heat dissipating fin, comprising:
 a main body; and   a plurality of through holes formed at the main body, wherein each of the through holes includes at least two collar portions, and the collar portions are formed on an edge of the through hole, and each of the collar portions includes a first extending portion and a first bridging portion, a first angle is formed between the first extending portion and the first bridging portion.   
     
     
         2 . The heat dissipating fin according to  claim 1 , wherein the first angle is an acute angle. 
     
     
         3 . The heat dissipating fin according to  claim 1 , wherein the diameter of the first extending portion is larger than the diameter of the first bridging portion. 
     
     
         4 . The heat dissipating fin according to  claim 1 , wherein the heat dissipating fin further includes at least two embedding slots formed at the main body, the embedding slot includes a second extending portion and a second bridging portion, and a second angle is formed between the second extending portion and the second bridging portion. 
     
     
         5 . The heat dissipating fin according to  claim 4 , wherein the second angle is an acute angle. 
     
     
         6 . The heat dissipating fin according to  claim 4 , wherein the diameter of the second extending portion is larger than the diameter of the second bridging portion. 
     
     
         7 . The heat dissipating fin according to  claim 1 , further comprising at least two flow deflectors disposed at the main body. 
     
     
         8 . A heat dissipating device, comprising:
 a base,   a heat dissipating fins set positioned on the base, wherein the heat dissipating fins set includes a plurality of heat dissipating fins, each of the heat dissipating fins includes:
 a main body; and 
 a plurality of through hole formed on the main body, each of the through holes includes at least two collar portions, and the collar portions are formed on an edge of the through hole, and each of the collar portions includes:
 a first extending portion and a first bridging portion, wherein a first angle is formed between the first extending portion and the first bridging portion; and 
 at least a pipe passing through the through holes of the heat dissipating fins. 
 
   
     
     
         9 . The heat dissipating device according to  claim 8 , further comprising a fan disposed at the heat dissipating fins set. 
     
     
         10 . The heat dissipating device according to  claim 8 , wherein the base further includes a plurality of ribs. 
     
     
         11 . The heat dissipating device according to  claim 8 , wherein the first angle is an acute angle. 
     
     
         12 . The heat dissipating device according to  claim 8 , wherein the diameter of the first extending portion is larger than the diameter of the first bridging portion. 
     
     
         13 . The heat dissipating device according to  claim 8 , wherein the heat dissipating fin further includes at least two embedding slots disposed at the main body, the embedding slot includes a second extending portion and a second bridging portion, and a second angle is formed between the second extending portion and the second bridging portion. 
     
     
         14 . The heat dissipating device according to  claim 13 , wherein the second angle is an acute angle. 
     
     
         15 . The heat dissipating device according to  claim 13 , wherein the diameter of the second extending portion is larger than the diameter of the second bridging portion. 
     
     
         16 . The heat dissipating device according to  claim 8 , further comprising at least two flow deflectors formed at the main body.
