And although the surface of the heat dissipation wing 130 may be flat as shown in FIG. 9, it may be desirable to increase the contact area with the outside air by forming the bent portion 131 on the surface as shown in FIG.

In addition, although the heat dissipation blades 130 protruding from one surface and the other surface of the heat dissipation piece 120 may protrude from the same position as shown in FIG. 9, it may be preferable to protrude from each other as shown in FIG. 11.

That is, the heat dissipation blades 130 protrudingly formed on the two heat dissipation pieces 120 facing each other are alternately disposed to face each other, and thus the alternate arrangement of the heat dissipation wings 130 is the heat dissipation piece 120. Air flowing into one side of the outflow to the other side is allowed to swing while passing between the heat dissipation wing 130.

In other words, the introduced air is quickly flowed out from one side of the heat dissipation piece 120 in the other direction, and escaped by shaking up and down like a vortex, while shaking up and down to the front and rear surfaces of the heat dissipation wing 130. By hitting repeatedly, the heat of the heat dissipation wing 130 is taken away.

The heat dissipating body (HS) according to the present invention having such a structure vertically on both sides of the heat dissipating piece 120 in addition to the plurality of heat dissipating pieces 120 protruding perpendicularly to the rear of the contact part 110 (that is, the contact part 110). Horizontally) is further provided with a plurality of heat dissipation wings 130, the heat dissipation blades 130 are formed with a bent portion 131, heat radiation by increasing the contact area with air to the maximum in the same volume of heat dissipating body (HS) High efficiency,

The heat dissipation blades 130 facing each other are alternately arranged so that the air flowing from one side of the heat dissipation piece 120 flows out to the other side quickly and shakes out so that the heat dissipation efficiency is higher.

In addition, by simplifying the structure can be produced in one extrusion process, it is excellent in productivity and economic efficiency.
