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 said containment vessel 5 is cylindric aluminum hull.Said containment vessel 5 inside are equipped with the combining jet device housing 11 of band fumarole 3 through anchor clamps 8; Said combining jet device housing 11 downsides are provided with flexible sheet 6; Said flexible sheet 6 lower ends are provided with piezoelectric patches 7; Said combining jet device housing 11 upsides are provided with heat-conducting plate 1, and said heat-conducting plate 1 edge is provided with two wire guides 4, evenly is provided with a plurality of thermal holes 9 on the said heat-conducting plate 1; Said heat-conducting plate 1 is provided with screw hole 10, and said fin 2 is installed on the heat-conducting plate 1 through screw hole 10.
As shown in Figure 2, said heat-conducting plate 1 is circular, and said thermal hole 9 evenly distributes around heat-conducting plate 1 center of circle.
As shown in Figure 1, said fin 2 is horn-like.
The course of work of the utility model synthesizing jet-flow formula active heat sink is: at first with this synthesizing jet-flow formula active heat sink.
At first this synthesizing jet-flow formula active heat sink is installed in the operating position; Lead passes wire guide 4 backs and links to each other with piezoelectric patches 7, 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 it is mobile to form air on horn-like fin 2 surfaces, thus realize active heat removal.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any restriction; Every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment did, all still belong in the protection domain of the utility model technical scheme.
