Fin assembly

Abstract

A fin assembly includes multiple first fins, multiple second fins and a heat pipe. An interval is formed between every two of the first fins which are neighboring to each other. The first fins and the second fins are alternately arranged with each other. The heat pipe penetrates through the plurality of first fins and the plurality of second fins. A partial volume of each second fin is disposed inside each interval, respectively.

What is claimed is: 
     
         1 . A fin assembly, comprising:
 a plurality of first fins, an interval being formed between every two of the plurality of first fins which are neighboring to each other;   a plurality of second fins, the plurality of first fins and the plurality of second fins being alternately arranged with each other; and   a heat pipe penetrating through the plurality of first fins and the plurality of second fins;   wherein a partial volume of each second fin is disposed inside each interval, respectively.   
     
     
         2 . The fin assembly according to  claim 1 , wherein the plurality of first fins are arranged as being equidistant from one another, and the plurality of second fins are arranged as being equidistant from one another. 
     
     
         3 . The fin assembly according to  claim 1 , wherein each first fin comprises a first surface, each second fin comprises a second surface, a projection area is formed inside the interval by projecting each first surface on each second surface, and an area ratio of the projection area to an area of the second surface is between 1% and 50%. 
     
     
         4 . The fin assembly according to  claim 3 , wherein the area ratio of the projection area to the area of the second surface is between 1% and 30%. 
     
     
         5 . The fin assembly according to  claim 1 , wherein each first fin comprises a first through hole, each second fin comprises a second through hole, and the heat pipe penetrates through each first through hole of each first fin and each second through hole of each second fin, respectively. 
     
     
         6 . The fin assembly according to  claim 5 , wherein each first fin and each second fin are rectangular plates, each first through hole is located at a center of each first fin, and each second through hole is located at a center of each second fin. 
     
     
         7 . The fin assembly according to  claim 5 , wherein each first fin and each second fin are rectangular plates, each first through hole is located far away from a center of each first fin, and each second through hole is located far away from a center of each second fin. 
     
     
         8 . The fin assembly according to  claim 7 , wherein each first fin comprises a first rectangular plate and a second rectangular plate which are connected to each other, each second fin comprises a third rectangular plate and a fourth rectangular plate which are connected to each other, the first through hole is located at a connection between the first rectangular plate and the second rectangular plate, and the second through hole is located at a connection between the third rectangular plate and the fourth rectangular plate. 
     
     
         9 . The fin assembly according to  claim 7 , wherein each first fin comprises a first triangular plate and a second triangular plate which are connected to each other, each second fin comprises a third triangular plate and a fourth triangular plate which are connected to each other, the first through hole is located at a connection between the first triangular plate and the second triangular plate, and the second through hole is located at a connection between the third triangular plate and the fourth triangular plate. 
     
     
         10 . The fin assembly according to  claim 1 , further comprising a solder continuously covering a section of the heat pipe inside the interval.
