Heat sink

Abstract

A heat sink includes a radiator fin for dissipating heat of an electronic device provided on a printed board; a plurality of radiator fins included in the heat sink is formed in an arbitrary diameter size; and the radiator fins are connected to each other by inserting a pair of fastening screws through a through hole provided on each of the radiator fins, and a tip end of the fastening screws is screwed and fastened to a screw hole of a base heat sink fixed on the upper surface of an electronic device.

1 . A heat sink comprising:
 radiator fins for dissipating heat of an electronic device provided on a printed board, wherein the heat sink is constructed by piling radiator fins formed in an arbitrary shape into multiple layers in a height direction and connecting the radiator fins.   
   
   
       2 . The heat sink according to  claim 1 , further comprising
 a base heat sink configured to be fixed on an electronic device provided on the printed board; and   a fastening unit that fastens the radiator fins into a multilayered state in the height direction.   
   
   
       3 . The heat sink according to  claim 1 , further comprising a fastening unit that fastens the radiator fins to each other, wherein
 the radiator fins are formed with a through hole that the fastening member pierces, and a screw hole with which a screw part formed at a tip end of the fastening member is to be screwed, and   the fastening unit pierces through holes of the radiator fins, and fastens the radiator fins into a multilayered state in the height direction by screwing into a screw hole of the radiator fins positioned underneath the radiator fins.   
   
   
       4 . The heat sink according to  claim 2 , wherein the fastening unit is a screw member that pierces a through hole formed at a certain position on the radiator fins under a state that the radiator fins are piled in multiple layers in the height direction, and is fastened to a screw hole formed at a certain position on the base heat sink. 
   
   
       5 . The heat sink according to  claim 2 , wherein
 the fastening unit includes a screw fastening member that can screw into a screw hole formed on an upper surface of the radiator fins and the screw hole provided underneath the radiator fins, and   the screw fastening member is configured to be screwed to a screw hole formed on an upper surface of the base heat sink.   
   
   
       6 . The heat sink according to  claim 2 , wherein
 the fastening unit includes a concave hole formed on an upper surface of the radiator fins and a convex member that can fit in the concave hole, the concave hole being provided underneath the radiator fins, and the convex member being configured to fit in a concave hole formed on an upper surface of the base heat sink.   
   
   
       7 . The heat sink according to  claim 1 , wherein the radiator fins are a structure in which a plurality of fins formed in an arbitrary shape is integrated. 
   
   
       8 . The heat sink according to  claim 1 , wherein the radiator fins are each formed in respective shapes in different sizes in accordance with an arrangement of electronic parts provided on the printed board. 
   
   
       9 . The heat sink according to  claim 1 , wherein the radiator fins are each formed in respective shapes in different sizes in accordance with a height of electronic parts provided on the printed board.
