Detailed description of the invention
the first embodiment
The present embodiment is set about from structure and the arrangement mode thereof of fin itself, does not increase the quantity of fin, also beyond fin, does not set up unnecessary radiator structure, by the heat radiation edge designs of fin being become to wavy concavo-convex to increase efficiently radiates heat area.Meanwhile, by making staggered corresponding arrangement of jog of adjacent fin, thereby form the space that is easy to heat radiation, increase radiating effect.
A kind of heat abstractor, comprises the fin 1 of multiple hollows that adjoin each other, and the inside of each fin 1 is formed with many oil guide groove 2; The upper/lower terminal of multiple fin 1 is provided with the adapter sleeve 3 of the hollow of horizontal direction extension, each fin 1 is connected to form between two oil through 4 by adapter sleeve 3, the dual-side of fin 1 is concavo-convex alternate curved edge, and concavo-convex alternate curved edge comprises projection 9 and sunk part 8; The projection 9 at each fin 1 edge is corresponding with the position of the sunk part 8 at fin 1 edge being adjacent.
The dual-side of fin 1 is wavy concavo-convex alternate curved edge, and wavy concavo-convex alternate curved edge comprises arc projection 9 and arc-shaped recess part 8.
Adopt above-mentioned two kinds of structures and arrangement mode, can realize the object that improves radiating effect, also can reduce die sinking quantity, reduce production costs.
In the first embodiment as shown in Figure 1 to Figure 3, the inside of each fin 1 is formed with 3 oil guide groove 2, and multiple fin 1 are formed alternately by two kinds of difform fin monomers.
The second embodiment
