"Tiny Cooling Fan" of technology and performance, with new technologies emerge. Size fan from 9mm to 20mm, voltage 5V, 12V, the shape of a square, circle and so on. Microblower 2008 microblower 2008, miniature "Tiny Cooling Fan" principle, miniature cooling fan works by energy conversion to be achieved, namely: energy → electromagnetic energy → mechanical energy → kinetic energy. The circuit is generally divided into a variety of forms, different uses of the circuit, there are differences "Tiny Cooling Fan" the performance will be.
