Abstract
A fluid system includes a fluid active region, a fluid channel, a convergence chamber and plural valves. The fluid active region includes one or plural fluid-guiding units. Each fluid-guiding unit includes an inlet plate, a substrate, a resonance plate, an actuating plate, a piezoelectric element and an outlet plate, which are stacked sequentially. The piezoelectric element is attached on the actuating plate. When the piezoelectric element drives a bending resonance of the actuating plate, the fluid is transported into the fluid-guiding units and pressurized to be discharged out. The fluid channel includes plural branch channels. The fluid discharged from the fluid active region is split by the branch channels. The convergence chamber is in communication with the fluid channel. The valves are disposed in the branch channels. The fluid is transported through the branch channels according to the open/closed states of the valves.
