Abstract
A gas transportation device includes a casing, a nozzle plate, a chamber frame, an actuator, an insulating frame and a conducting frame, which are stacked sequentially. A cuboidal resonance chamber is defined by the actuator, the chamber frame and a suspension plate of the nozzle plate collaboratively. When the actuator is driven, the nozzle plate is subjected to a resonance and the suspension plate of the nozzle plate vibrates in the reciprocating manner. Consequently, the gas is transported to a gas-guiding chamber through at least one interspace and discharged from the discharging opening so as to implement the gas circulation.
