Heat dissipation device with good appearance

Abstract

A heat dissipation device for a heat-generating component includes a heat dissipation fin group and a side plate. The heat dissipation fin group comprises a plurality of heat dissipation fins arranged one on the other, each of the heat dissipation fins comprises a base plate and a fold extending vertically from a side of the base plate. The folds of the heat dissipation fins located at a common side are combined with each other to form a side surface. The side plate covers the side surface of the heat dissipation fin group, and an exposed surface of the side plate includes a plurality of strips formed thereon.

1 . A heat dissipation device for a heat-generating component, the heat dissipation device comprising:
 a heat dissipation fin group comprising a plurality of heat dissipation fins arranged one on the other, each of the heat dissipation fins comprising a base plate and a fold extending vertically from a side of the base plate, the folds of the heat dissipation fins located at a common side combined with each other to form a side surface; and   a side plate covering the side surface of the heat dissipation fin group, an exposed surface of the side plate comprising a plurality of strips formed thereon.   
     
     
         2 . The heat dissipation device of  claim 1 , wherein the strips of the exposed surface of the side plate are corresponding to connecting lines between the adjacent folds of the heat dissipation fins. 
     
     
         3 . The heat dissipation device of  claim 1 , wherein the exposed surface is consisted of a plurality of substantially horizontal lines. 
     
     
         4 . The heat dissipation device of  claim 1 , wherein the base plate is rectangular and the folds are elongated strips. 
     
     
         5 . The heat dissipation device of  claim 1 , wherein an area of the exposed surface of the side plate is equal to that of the side surface of the heat dissipation fin group. 
     
     
         6 . The heat dissipation device of  claim 1 , wherein the side plate is made of the same material with the heat dissipation fin. 
     
     
         7 . The heat dissipation device of  claim 1 , wherein the side plate comprises a main body and a plurality of L-shaped hooks extending outwardly from two opposite edges of the main body, the hooks are corresponded to couple with the fold of the heat dissipation fin.
