In this paper, the optimization is carried out for a synthetic jet based piezoelectric air pump. The structural parameters which affect the output flowrate are determined and orthogonal test method is used to find out the optimal values of these parameters. Driven by a 150 Vpp, 3.15 kHz sinusoidal voltage signal, the optimized pump reaches its maximum output flowrate of 2.79 L/min, which is 32.9% higher than that before optimization. Using the synthetic jet based piezoelectric air pump as gas source, an open-loop detection and closed-loop control system is built for electronic cooling. The open-loop experiments show that the heater’s surface temperature can be maintained at around 97.9 °C when the cooling distance is 60 mm, which is 32.5% lower than the initial value. The closed-loop control system can limit the temperature within the set interval. Both the open and closed-loop system show that the synthetic jet based piezoelectric air pump has application prospects in the field of electronic cooling.
