Integration of Fin and Piezoelectric Vibration Fan(FinFan) to force air flow for cooling notebook computer is
proposed. The air flow is forced through the flexible‐stretchable material, where the piezoelectric element
is placed on. Example of the system module for cooling notebook computer is illustrated.
The ultra‐compact piezoelectric FinFan that is thin enough to be installed in the gaps between parts, and to
develops a high enough pressure to generate sufficient flow rate within the narrow gaps found in densely
packed electronics. There is no compression concern as there is no running axial motor like normal blower
