Patent number: 11306711Abstract: 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.Type: GrantFiled: August 30, 2018Date of Patent: April 19, 2022Assignee: CHUNG-YUAN CHRISTIAN UNIVERSITYInventors: Yung Ting, Sheuan-Perng Lin, Chien-Ping Wang, Chien-Hsiang Wu, Jun-Hao Chen

Patent number: 10564011Abstract: A linear piezoelectric motor and a slider drive system thereof are disclosed. The linear piezoelectric motor includes a piezoelectric ceramic element and a base structure. The piezoelectric ceramic element includes a first region, a second region and an interval region located between the first and the second region, wherein the first and the second region may be formed by a first and a second power signal supplied by a power supply to form a first and a second standing wave, respectively. The interval region is a quarter wavelengths. The first and the second standing wave have a phase difference so as to form a traveling wave. The base structure disposes the piezoelectric ceramic element and has a pectinate structure to increase the amplitude of the first and the second standing wave, thereby enabling the piezoelectric motor to be driven.Type: GrantFiled: January 24, 2018Date of Patent: February 18, 2020Assignee: CHUNG-YUAN CHRISTIAN UNIVERSITYInventors: Yung Ting, Sheuan-Perng Lin, Chien-Hsiang Wu
