The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of synthesizing jet-flow formula active heat sink is provided, it is reasonable in design, and is simple in structure, good looking appearance, anti-dust contamination resistance is strong, and reliability is high, and volume is little, lightweight, durability is high, and heat dissipation capacity is large, without any noise.
for achieving the above object, the technical solution used in the present invention is: a kind of synthesizing jet-flow formula active heat sink, comprise fin and containment vessel, it is characterized in that: described containment vessel inside is equipped with combining jet device housing with fumarole by fixture, described combining jet device housing downside is provided with flexible sheet, described flexible sheet lower end is provided with piezoelectric patches, described combining jet device housing upside is provided with heat-conducting plate, described heat-conducting plate edge is provided with two wire guides, evenly be provided with a plurality of thermal holes on described heat-conducting plate, be provided with screw hole on described heat-conducting plate, described fin is arranged on heat-conducting plate by screw hole.
Described heat-conducting plate is circular, and described thermal hole evenly distributes around the heat-conducting plate center of circle.
Described fin is horn-like.
Described containment vessel is cylindric aluminum hull.
The present invention compared with prior art has the following advantages:
(1) this synthesizing jet-flow formula active heat sink is reasonable in design, simple in structure, and it is horn-like that profile is, elegant in appearance.
(2) the anti-dust contamination resistance of this synthesizing jet-flow formula active heat sink is very strong, and reliability is very high.
(3) this synthesizing jet-flow formula active heat sink size is 1/3rd of common radiator, and is lightweight, is convenient to very much carrying, transportation and installs.
(4) this synthesizing jet-flow formula active heat sink durability is high, dispels the heat by combining jet device, and heat dissipation capacity improves greatly, and without any noise.
Below by drawings and Examples, the present invention is described in further detail.

The specific embodiment
A kind of synthesizing jet-flow formula active heat sink as depicted in figs. 1 and 2 comprises fin 2 and containment vessel 5, and described containment vessel 5 is cylindric aluminum hull.Described containment vessel 5 inside are equipped with combining jet device housing 11 with fumarole 3 by fixture 8; described combining jet device housing 11 downsides are provided with flexible sheet 6; described flexible sheet 6 lower ends are provided with piezoelectric patches 7; described combining jet device housing 11 upsides are provided with heat-conducting plate 1; described heat-conducting plate 1 edge is provided with two wire guides 4; evenly be provided with a plurality of thermal holes 9 on described heat-conducting plate 1; be provided with screw hole 10 on described heat-conducting plate 1, described fin 2 is arranged on heat-conducting plate 1 by screw hole 10.
As shown in Figure 2, described heat-conducting plate 1 is circular, and described thermal hole 9 evenly distributes around heat-conducting plate 1 center of circle.
As shown in Figure 1, described fin 2 is horn-like.
The course of work of synthesizing jet-flow formula active heat sink of the present invention is: at first with this synthesizing jet-flow formula active heat sink.
At first this synthesizing jet-flow formula active heat sink is arranged on the operating position, wire is connected with piezoelectric patches 7 after passing wire guide 4, and to piezoelectric patches 7 output periodic electrical signal, piezoelectric patches 7 drives flexible sheet 6 vibrations under the periodic electrical signal excitation, thereby make the fumarole 3 places ejection gas of combining jet device housing 11 form jet, thermal hole 9 ejections of jet on heat-conducting plate 1, and at horn-like fin 2 surface formation Air Flows, thereby realize active heat removal.
The above; it is only preferred embodiment of the present invention; be not that the present invention is imposed any restrictions, every according to the technology of the present invention essence to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection domain of technical solution of the present invention.
