Abstract
A miniature cooling system includes a base metal sheet, a flow channel layer, a piezoelectrically actuated metal sheet, a piezoelectric boundary compression layer and two piezoelectric ceramic vibrators. The flow channel layer is located on the base metal sheet and includes a first chamber, a second chamber, an inlet channel, a linking channel and an outlet channel. The inlet channel links the outside environment to the first chamber. The linking channel links the first chamber and the second chamber. The outlet channel links the second chamber to the outside environment. The piezoelectrically actuated metal sheet is located on the flow channel layer. The piezoelectric boundary compression layer is located on the piezoelectrically actuated metal sheet. The piezoelectric boundary compression layer includes two containing areas, and the two containing areas are respectively located above the first chamber and the second chamber.
