Heat dissipation device which is pre-built with an air vent structure

Abstract

A heat dissipation device which is pre-built with an air vent structure uses primarily a plurality of cooling fins, which are formed into different lengths, to assemble into the heat dissipation devices of different shapes, for shunning away from other elements inside a computer host. In addition, diversion baffles of a different angle can be arranged and assembled, so as to form air ducts following an angle of wind direction, allowing an air flow to be smoothly guided in by a fan, and to quickly flow into a heat transmission zone in a gap between the cooling fins, such that a heat source can be dissipated more quickly.

1 . A heat dissipation device which is pre-built with an air vent structure being assembled by connecting a plurality of cooling fins, with the cooling fin being bended with heat transmission wings to form a plurality of heat transmission zones in merging; each of the cooling fins being provided with an extension section of different length which is pre-assembled to form a variation of shapes and a plurality of diversion baffles; the diversion baffles being formed with a certain angle according to air outlets, and forming a bus duct, such that an air flow is smoothly guided when a fan is operating, allowing a cold air to quickly flow toward the heat transmission zone in a gap between the cooling fins, thereby allowing a heat source to be dissipated more quickly. 
     
     
         2 . The heat dissipation device which is pre-built with an air vent structure, according to  claim 1 , wherein the plural cooling fins are formed and assembled integrally by punching.
