Abstract

A heat sink comprises a plurality of heat-dissipating units, and each heat-dissipating unit provides a base and a plurality of parallel fins disposed thereon, respectively. The fins of any two adjacent heat-dissipating units extend in different directions.

Claims

exact text as granted — not AI-modified
1 . A heat sink, comprising: 
 a plurality of heat-dissipating units, each of which provides a base and a plurality of parallel fins disposed on the base, wherein the fins of any two adjacent heat-dissipating units are connected and extended in different directions individually.    
   
   
       2 . The heat sink as claimed in  claim 1 , wherein each heat-dissipating unit further comprises a welding region located at the periphery of the base thereof to connect to another heat-dissipating unit.  
   
   
       3 . The heat sink as claimed in  claim 1 , wherein the base and the fins of the heat-dissipating unit are integrally formed.  
   
   
       4 . The heat sink as claimed in  claim 3 , wherein the base and the fins of the heat-dissipating unit are made of copper, copper alloy, aluminum or aluminum alloy.  
   
   
       5 . The heat sink as claimed in  claim 1 , wherein the base and the fins of the heat-dissipating unit are connected by welding.  
   
   
       6 . The heat sink as claimed in  claim 5 , wherein the base and the fins of the heat-dissipating unit are made of copper, copper alloy, aluminum or aluminum alloy.  
   
   
       7 . The heat sink as claimed in  claim 1 , wherein the heat-dissipating unit further comprises a plurality of slots formed on an upper surface of the base thereof, and the fins are disposed in the slots respectively.  
   
   
       8 . The heat sink as claimed in  claim 1 , wherein the base of the heat-dissipating unit comprises a polygonal column with at least three faces.  
   
   
       9 . The heat sink as claimed in  claim 1 , wherein the base of the heat-dissipating unit comprises a sectorial column.  
   
   
       10 . The heat sink as claimed in  claim 1 , wherein any two adjacent heat-dissipating units are connected by welding.  
   
   
       11 . The heat sink as claimed in  claim 1 , wherein the bases of each heat-dissipating unit are connected via a low thermo-resistant conductive adhesive or glue.  
   
   
       12 . The heat sink as claimed in  claim 1 , wherein the fins of any two adjacent heat-dissipating units are substantially orthogonally connected.  
   
   
       13 . The heat sink as claimed in  claim 1 , wherein the heat-dissipating unit comprises a plurality of straight fins.  
   
   
       14 . The heat sink as claimed in  claim 1 , wherein the fins of the heat-dissipating unit are not curved.  
   
   
       15 . A heat sink, comprising: 
 a plurality of heat-dissipating units, each of which provides a base and a plurality of parallel fins disposed on the base, wherein no gap exists between the connected fins of any two adjacent heat-dissipating units.    
   
   
       16 . The heat sink as claimed in  claim 15 , wherein the heat-dissipating unit comprises a plurality of straight fins.  
   
   
       17 . The heat sink as claimed in  claim 15 , wherein the fins of the heat-dissipating unit are not curved.
