2. Piezo Fan Working Theory
 The main working theory for piezo fan is to use the vibration from the
piezo ceramic so that the fan sleeve will vibrate together with the piezo
ceramic. When a certain voltage signal is input to the piezo ceramic,
the piezo ceramic will have an up-and-down transform, by using this
transform from the piezo ceramic, the fan sleeve which is attached to
the piezo ceramic will be moved together with the piezo ceramic,
which creates the wide in a certain unique direction.

6. Piezo Fan Installation
 (1),Direct cooling on the unit
Wide
Outlet
Unit that needs
to be cool down
Piezo Fan
It is better to install the piezo fan in a parallel
way or 90°way to the unit that needs to be cool
down and the wide outlet should be in the same
direction of the wide direction
(2)Work with Radiator
Piezo Fan
Radiatior
To work with a Radiator, the wind from the piezo fan
is directly facing the radiator so as to accelerate the
heat exchange and to achieve a better cooling
condition
Other issues:
(1),Can be used by directly AC power
Now, our company has 110V/50HZ, 110V/60HZ,
220V/50HZ,which is covering all the electric standards
all over the world
(2),DC Power
We also have DC power type, but this DC power type
needs to add a drive circuit to transfer the DC input.
