It is shaken by the reversed back and forth of the first piezoelectric vibrator structure to the 4th piezoelectric vibrator structure of 1 two sides of rectangular cavities,
Compression simultaneously and expand simultaneously so that gas compression and expansion in rectangular cavities 1, when compression, i.e., outlet when, the cone at top
Body 32 is blown open, and gas is excluded from bellmouth 31, and the bullet 32 of bottom causes since airflow function is pressed in bellmouth 31
It cannot go out from this hole.Upon expansion, i.e., air inlet when, exactly the opposite, i.e., the bellmouth 31 of bottom can be with air inlet, and top is just
It is not all right.Thermal column 51 is formed since fuel factor, heat can rise bottom-up with the suction hole of 1 lower section of rectangular cavities
Airflow direction is identical, that is, and respiratory state is formed, that is, siphons away the hot-air of lower section, is then discharged from the bellmouth 31 at top, it is cold
Air passes through thermal column 51 from surrounding again.Reciprocal Rapid Circulation, achievees the purpose that heat dissipation.Wherein, the present invention is due to using vertical
Design, space utilization rate is high, will not occupy any transverse area in addition to heat-radiating substrate 5.2, due to vertical structure, process is shaken
In, the problem of being not in leverage, heat-radiating substrate 5 is caused to separate with chip, compactness is higher, and spoilage is lower；In addition
Using non-contacting spring structure, in realization the ventilation lumen of part slight lateral vibration absorbed by spring, do not influence under
Heat-radiating substrate 5.3, using air-suction, i.e., by the valve body of taper, 1 bottom air-breathing of rectangular cavities is realized, rectangular cavities 1
Top is only deflated, suction hole of the thermal column 51 since fuel factor, heat can rise bottom-up, with 1 lower section of rectangular cavities
The airflow direction of formation is identical, and two speed do not have differential seat angle, and heat dissipation effect is more preferable after superposition.
In the present embodiment, air hole structure quantity at least two that 1 bottom surface of rectangular cavities is equipped with.In the present embodiment, rectangle
The air hole structure quantity at least two that 1 top surface of cavity is equipped with.It can be effectively.
In the present embodiment, 51 arrangement mode of thermal column is that is set to first heat dissipation of 5 end face center of heat-radiating substrate
Column 51, the second circle thermal column 51 that first thermal column 51 of the circle around center is placed equidistant with, and around the second circle thermal column
The 51 third circle thermal columns 51 being placed equidistant with；The height of first thermal column 51 is greater than the second circle thermal column 51, the second circle thermal column
51 height is greater than third circle thermal column 51.In this way in practice, discovery can effectively promote cold air and reach in thermal column 51
Heart district domain is conducive to radiate.
In the present embodiment, the thermal column 51 be hollow structure, 51 bottom of thermal column set there are two penetrate through air inlet
Through-hole 52.Thermal column 51 is designed as hollow structure, and bottom offers air through hole 52, and the heat in thermal column 51 is passed through bottom
The air of air inlet rises to the region at top, and better heat-radiation effect is obvious.
The above is only a preferred embodiment of the invention, therefore all according to structure described in present patent application range
It makes, the equivalent change or modification that feature and principle are done, in the protection scope of present patent application.
