A valveless piezoelectric pump with multistage Y-shape treelike bifurcate tubes
At present, liquid cooling system employed piezoelectric pump, in which valve limits reliability and miniaturization of the piezoelectric pump and liquid cooling system. For this problem, a valveless piezoelectric pump with multistage Y-shape treelike bifurcate tubes is developed in this research. Firstly, a multistage Y-shape treelike bifurcate tube was proposed, then a valveless piezoelectric pump with multistage Y-shape treelike bifurcate tubes was designed and its working principle was analyzed. Then, the theoretical analysis of flow resistance characteristics and the flow rate of the valveless piezoelectric pump were performed. Finally, this valveless piezoelectric pump was fabricated, the relationships between the flow rates and driving frequency, as well as the relationship between the back pressure and the driving frequency were experimentally investigated. The experimental results showed that the maximum flow rate was 35.6 ml/min under 100V (10.3Hz) power supply, and the maximum back pressure was 55mm H2O under 100V (9Hz) power supply. The experimental results validated the feasibility of the valveless piezoelectric pump with multistage Y-shape treelike bifurcate tubes.
