Abstract

A fluid system includes a fluid active region, a fluid channel, a convergence chamber, a sensor and plural valves. The fluid active region includes at least one fluid-guiding unit. The fluid-guiding unit is enabled under control to transport fluid to be discharged out through an outlet aperture. The fluid channel is in communication with the outlet aperture of the fluid active region, and has plural branch channels for splitting the fluid discharged from the fluid active region. The convergence chamber is in communication with the fluid channel. The sensor is disposed in the fluid channel for measuring fluid. The valves each of which is disposed in the corresponding branch channel, wherein the fluid is discharged out through the branch channels according to opened/closed states of the valves under control. The fluid system is capable of acquiring required flow rate, pressure and amount of the fluid to be transported.

First claim

What is claimed is:

1. A fluid system, produced by an integrated method, the fluid system comprising:
a fluid active region comprising at least one fluid-guiding unit, wherein the fluid-guiding unit is enabled under control to transport fluid to be discharged out through at least one outlet aperture;
a fluid channel in communication with the at least one outlet aperture of the fluid active region, and having plural branch channels to split the fluid discharged from the fluid active region, so that a specific required amount of the fluid to be transported is determined;
a convergence chamber in communication with the plural branch channels of the fluid channel and disposed for allowing the fluid to be accumulated and stored therein, when the fluid system is under control to discharge the specific required amount of the fluid, the convergence chamber can supply the fluid to the fluid channel so as to increase the amount of the fluid to be transported;
a sensor disposed in the fluid channel to measure the fluid within the fluid channel; and
a plurality of valves each of which disposed in the corresponding branch channel, wherein each of the plurality of valves is an active valve, and the fluid is discharged out through the branch channels according to opened/closed states of the plurality of valves under control;
wherein the opened/closed states of the plurality of valves is controlled by a controller, so as to actively transport the fluid accumulated and stored in the convergence chamber to the fluid channel.

2. The fluid system according to claim 1 , wherein the at least one fluid-guiding unit of the fluid active region comprises plural fluid-guiding units, and the plural fluid-guiding units are connected with each other and disposed in a serial arrangement to transport the fluid.

3. The fluid system according to claim 1 , wherein the at least one fluid-guiding unit of the fluid active region comprises plural fluid-guiding units, and the plural fluid-guiding units are connected with each other and disposed in a parallel arrangement to transport the fluid.

4. The fluid system according to claim 1 , wherein the at least one fluid-guiding unit of the fluid active region comprises plural fluid-guiding units, and the plural fluid-guiding units are connected with each other and disposed in a serial-and-parallel arrangement to transport the fluid.

5. The fluid system according to claim 1 , wherein the at least one fluid-guiding unit of the fluid active region comprises plural fluid-guiding units, and the plural fluid-guiding units are connected with each other and disposed in a ring-shaped arrangement to transport the fluid.

6. The fluid system according to claim 1 , wherein the at least one fluid-guiding unit of the fluid active region comprises plural fluid-guiding units, and the plural fluid-guiding units are connected with each other and disposed in a honeycomb arrangement to transport the fluid.

7. The fluid system according to claim 1 , wherein the fluid-guiding unit is a piezoelectric pump.

8. The fluid system according to claim 1 , wherein the lengths of the plural branch channels are preset according to the specific required amount of the fluid to be transported.

9. The fluid system according to claim 1 , wherein the widths of the plural branch channels are preset according to the specific required amount of the fluid to be transported.

10. The fluid system according to claim 1 , wherein the controller and the at least one fluid-guiding unit are made by a system-in-package manner to form an integrated structure.

11. The fluid system according to claim 1 , wherein the plural branch channels are connected with each other and disposed in a serial arrangement.

12. The fluid system according to claim 1 , wherein the plural branch channels are connected with each other and disposed in a parallel arrangement.

13. The fluid system according to claim 1 , wherein the plural branch channels are connected with each other and disposed in a serial-and-parallel arrangement.

14. A fluid system, produced by an integrated method, the fluid system comprising:
at least one fluid active region comprising at least one fluid-guiding unit, wherein the fluid-guiding unit is enabled under control to transport fluid to be discharged out through at least one outlet aperture;
at least one fluid channel in communication with the at least one outlet aperture of the fluid active region, and having plural branch channels to split the fluid discharged from the fluid active region, so that a specific required amount of the fluid to be transported is determined;
at least one convergence chamber in communication with the plural branch channels of the fluid channel and disposed for allowing the fluid to be accumulated and stored therein, when the fluid system is under control to discharge the specific required amount of the fluid, the at least one convergence chamber can supply the fluid to the fluid channel so as to increase the amount of the fluid to be transported;
at least one sensor disposed in the fluid channel to measure the fluid within the fluid channel; and
a plurality of valves each of which disposed in the corresponding branch channel, wherein each of the plurality of valves is an active valve, and the fluid is discharged out through the branch channels according to opened/closed states of the plurality of valves under control;
wherein the opened/closed states of the plurality of valves is controlled by a controller, so as to actively transport the fluid accumulated and stored in the convergence chamber to the fluid channel.
