A kind of driving type piezoelectric actuator heat radiation module；The problem of although structure solves conventional fan radiator.But itself has such as
Under important shortcoming：1st, low space utilization；Radiator portion and ventilation lumen are laterally set side by side, and ventilation lumen simultaneously takes circuit board
Horizontal area, blocks other electronic components, and the heat dissipation problem of other electronic components is caused on the contrary.2nd, vibration problems, with piezoelectricity
The use of heat radiation module, time length can find that the degree that the chips such as heat-radiating substrate and CPU are fitted is more and more lower, be primarily due to this
Structure radiator portion and ventilation lumen in patent link together, and a leverage is formed when ventilation lumen vertical tremor will
The heat-radiating substrate on side is tilted, the problem of being very easy to cause to radiate bad.3rd, the heat radiation module of the structure belongs to blowing method
Radiating, i.e., by the air extrusion in ventilation lumen and blow to thermal column（That is the shunting body of the patent）, the form actual efficiency is low, because
It is thermal column due to fuel factor, hot gas is to rise bottom-up around it, and the transverse direction of ventilation lumen is blown to be caused with fuel factor
The bottom-up motion of gas form a differential seat angle, the actual speed that hot gas scatters is reduced on the contrary.4th, the structure is scattered
Plume（That is the shunting body of the patent）For solid construction, reduce due to air radiating rate caused by fuel factor.
