Heat-dissipating fin assembly and assembling method thereof

Abstract

A heat-dissipating fin assembly including a first fin and a second fin is provided. Each of the first fin and the second fin respectively includes a body, a bending part and a connecting part. The bending part is bent from an end of the body to form a turning portion along a predetermined direction. The connecting part, located near a turning portion of the bending part from the end of the body, extends opposite to the predetermined direction. When the first fin is connected to the second fin, the connecting part of the first fin is connected with the second fin. Also, an assembling method of the heat-dissipating fin assembly is provided.

       2 . The heat-dissipating fin assembly as claimed in  claim 1 , wherein the connecting part extends opposite to the predetermined direction to form an end comprising a welding surface. 
   
   
       3 . The heat-dissipating fin assembly as claimed in  claim 2 , wherein the bending part further comprises an end surface, and when the first fin is connected with the second fin, the end surface of the bending part of the first fin is connected with the welding surface of the connecting part of the second fin. 
   
   
       4 . The heat-dissipating fin assembly as claimed in  claim 2 , wherein the bending part is bent from the body to form a guiding angle or a round angle. 
   
   
       5 . The heat-dissipating fin assembly as claimed in  claim 1 , wherein the connecting part extends from the turning portion of the bending part and outwardly protrudes from the turning portion. 
   
   
       6 . The heat-dissipating fin assembly as claimed in  claim 5 , wherein an end of the bending part comprises an indentation disposed with respect to the connecting part of an adjacent fin. 
   
   
       7 . The heat-dissipating fin assembly as claimed in  claim 6 , wherein when the first fin is connected with the second fin, the connecting part of the second fin is disposed with respect to the indentation of the first fin and is connected with the first fin. 
   
   
       8 . The heat-dissipating fin assembly as claimed in  claim 1 , wherein the first fin is connected with the second fin by welding, spot gluing or adhering onto the connecting part of the first fin and the second fin. 
   
   
       9 . The heat-dissipating fin assembly as claimed in  claim 8 , wherein the welding comprises laser spot welding or argon welding. 
   
   
       10 . The heat-dissipating fin assembly as claimed in  claim 1 , wherein the first fin and the second fin comprise copper, aluminum, iron, magnesium or alloys thereof. 
   
   
       11 . A method of assembling the heat-dissipating fin, comprising steps of:
 stamping a sheet material to form a first fin and a second fin, wherein each of the first fin and the second fin comprises a body, a bending part and a connecting part the bending part is bent from an end of the body to form a turning portion along a predetermined direction, and the connecting part, near the turning portion of the bending part at the end of the body, extends opposite to the predetermined direction;   arranging the first fin and the second fin straight and upright in order; and   connecting the first fin with the second fin, wherein the connecting part of the first fin is connected with the second fin.   
   
   
       12 . The method as claimed in  claim 11 , wherein the sheet material is stamped by a tool machine, or a stamping machine. 
   
   
       13 . The method as claimed in  claim 11 , wherein the connecting part extends opposite to the predetermined direction to form an end comprising a welding surface. 
   
   
       14 . The method as claimed in  claim 13 , wherein the bending part further comprises an end surface, and when the first fin is connected with the second fin, the end surface of the bending part of the first fin is connected with the welding surface of the connecting part of the second fin. 
   
   
       15 . The method as claimed in  claim 13 , wherein the bending part is bent from the body to form a guiding angle or a round angle. 
   
   
       16 . The method as claimed in  claim 11 , wherein the connecting part extends from the turning portion of the bending part and outwardly protrudes from the turning portion. 
   
   
       17 . The method as claimed in  claim 16 , wherein an end of the bending part comprises an indentation disposed with respect to the connecting part of an adjacent fin, and when the first fin is connected with the second fin, the connecting part of the second fin is disposed with respect to the indentation of the first fin and is connected with the first fin. 
   
   
       18 . The method as claimed in  claim 11 , wherein the first fin is connected with the second fin by welding, spot gluing or adhering, onto the connecting part of the first fin and the second fin. 
   
   
       19 . The method as claimed in  claim 18 , wherein the welding comprises laser spot welding or argon welding. 
   
   
       20 . The method as claimed in  claim 11 , wherein the first fin and the second fin comprise copper, aluminum, iron, magnesium or alloys thereof.
