Also, other various embodiments are possible.

1 . A heat dissipation device comprising:
 a heat dissipation plate; and   heat dissipation areas provided on the heat dissipation plate, wherein heat dissipation fins having different angles are provided in the heat dissipation areas.   
     
     
         2 . The heat dissipation device as claimed in  claim 1 , wherein an inset portion is provided between the heat dissipation areas adjacent to each other. 
     
     
         3 . The heat dissipation device as claimed in  claim 2 , wherein the heat dissipation fins formed in the heat dissipation areas adjacent to each other are provided to form the shape of “V” with respect to the inset portion. 
     
     
         4 . The heat dissipation device as claimed in  claim 2 , wherein the inset portion comprises at least two inset lines that are formed to cross each other or to be bent. 
     
     
         5 . The heat dissipation device as claimed in  claim 4 , wherein the inset lines of the inset portion are formed on the heat dissipation plate to cross each other in the shape of “+,” and the heat dissipation areas comprise first to fourth heat dissipation areas divided from each other with respect to the inset lines. 
     
     
         6 . The heat dissipation device as claimed in  claim 5 , wherein first to fourth heat dissipation fins in the first to fourth heat dissipation areas have different angles to form the shape of “X” with respect to the central portion of the inset lines. 
     
     
         7 . The heat dissipation device as claimed in  claim 5 , wherein first to fourth heat dissipation fins in the first to fourth heat dissipation areas have different angles to form a rhombic shape with the central portion of the inset lines as the center thereof. 
     
     
         8 . The heat dissipation device as claimed in  claim 4 , wherein the inset lines of the inset portion cross each other in the shape of “X” on the heat dissipation plate, the heat dissipation areas comprise first to fourth heat dissipation areas divided from each other with respect to the inset lines, and first to fourth heat dissipation fins in the first to fourth heat dissipation areas have different angles to form the shape of “+” with respect to the central portion of the inset lines. 
     
     
         9 . The heat dissipation device as claimed in  claim 1 , wherein each of the heat dissipation fins comprises at least one of a corrugated portion, a groove, a protrusion, and an opening to form a turbulent flow. 
     
     
         10 . The heat dissipation device as claimed in  claim 1 , wherein the heat dissipation areas adjacent to each other are provided in a symmetric structure with respect to the inset portion.
