Along the cavity, one heat dissipation channel is set；
In the outer surface heat abstractor, cold and hot exchange air-flow flows along cavity 4 and the heat dissipation channel.
The heat dissipation channel specifically sets as follows：
One cavity breach is set between the cavity 4 and fin cover plate 1；
Also include a wind guide strip 5, the laminating cavity breach of the wind guide strip 5 is installed, and forms a wind-guiding gap with fin cover plate 1
6；
Fig. 3 is partial schematic diagram of the invention, as shown in figure 3, the fin cover plate 1 is provided with above-mentioned wind-guiding gap location leading
Air holes 7, along the air-guiding hole 7, offers wind guide tank 8 on fin cover plate 1, the wind guide tank 8 is formed by fin, described
Fin is milled out on fin cover plate, and the design reduces the volume of heat abstractor while radiating effect is ensured, makes
The heat abstractor is more succinct.
The air-guiding hole 7 and wind guide tank 8 are corresponded, and are connected and are set, as shown in Figure 4.
The wind guide strip 5 install when with fin cover plate 1 formed a gradient, the gradient α between 15 ° -30 °, such as Fig. 3
It is shown.
The corresponding fin cover plate of the wind guide strip 5（As described in Figure 1, the left side of wind guide tank）Thickness be less than cavity 4 pairs
The thickness of the fin cover plate answered, the design increases wind-guiding clearance space, meanwhile, the thickness of air-guiding hole is reduced again, favorably
Wind-guiding gap is flowed into from cavity and successively through air-guiding hole, wind guide tank outflow, improve radiating efficiency in hot-air.
The radiator fan is low speed low-noise fan 3.
The radiator fan is just to being arranged on at air holes 2.
Fig. 5 be it is of the invention enter vent structure schematic diagram, as described in Figure 5, it is described enter air holes 2 shape hollow type, by many
Individual small air holes composition, each small air holes is shaped as circle, overall rounded arrangement.The need for according to radiating, can suitably increase
It is described enter air holes 2 quantity, the quantity of radiator fan is consequently increased.
The air-guiding hole is shaped as arc or semicircle.
The wind guide strip has a horizontal extension 5-1 in wind-guiding gap location, is prolonged the wind guide strip level by screw
Extending portion point is fixed on fin upper cover plate, and the effect of another aspect wind guide strip horizontal continuation is hot blast is gone out from wind-guiding gap
To be flowed along the direction of air-guiding hole and wind guide tank.
As shown in figure 1, multiple cavity wall screw holes 13 are provided with the cavity wall of the cavity 4, the cavity wall screw
