Bent-type heat dissipater

Abstract

Disclosed is a bent-type dissipater, including one or a plurality of heat sinks which are adapted with cooling apertures; one or a plurality of cooling pins which are bent in structure, and which are integrated to the heat sinks, and a central heat passage for combining heat moving in one direction with ambient air, and discharging the heat in the opposite direction.

1 . A bent-type heat dissipater comprising:
 a heat dissipation plate having one or a plurality of cooling holes that form passages to discharge heat, which transfers in one direction, together with external air in the opposite direction; and   one or a plurality of heat dissipation fins integrally bending from the heat dissipation plate.   
     
     
         2 . The bent-type heat dissipater of  claim 1 , wherein the cooling hole is formed at the center of the heat dissipation plate. 
     
     
         3 . The bent-type heat dissipater of claim of  claim 1 , wherein the cooling hole is shaped in any one of a circle, an ellipse, and a polygon. 
     
     
         4 . The bent-type heat dissipater of  claim 1 , wherein the inner diameter of the cooling hole is 6.5 to 80% of the outer diameter of the heat dissipation plate. 
     
     
         5 . The bent-type heat dissipater of  claim 1 , wherein the cooling hole further has a plurality of sub-cooling grooves along the inner circumference. 
     
     
         6 . The bent-type heat dissipater of  claim 1 , wherein the heat dissipation fins are integrally bent up along the edge of the heat dissipation plate and have a predetermined length upward. 
     
     
         7 . The bent-type heat dissipater of  claim 6 , wherein the heat dissipation fins are inclined at a predetermined angle toward the center with respect to the top of the heat dissipation plate. 
     
     
         8 . The bent-type heat dissipater of  claim 7 , wherein the inclination angle of the heat dissipation fins is changed by selectively bending. 
     
     
         9 . The bent-type heat dissipater of  claim 1 , wherein the heat dissipation fins further have one or a plurality of sub-holes to pass heat, which flows inside from the cooling hole, to the outside. 
     
     
         10 . The bent-type heat dissipater of  claim 1 , wherein the heat dissipation fins are formed at regular intervals, and
 a plurality of sub-heat dissipation fins is further disposed at the gaps between the heat dissipation fins, along the regular edge of the heat dissipation plate in order to increase a heat dissipation area.   
     
     
         11 . The bent-type heat dissipater of  claim 10 , wherein the sub-heat dissipation fins are formed in any one of a shape bent in one direction to have a plurality of steps and a zigzag shape alternately bent in two directions to have a plurality of steps.
