Design of a wave cooling system using design of experiments

The wave energy of sound and ultrasound has been widely used in industries such as cleaning, medical sensors, and manufacturing. In this paper, the design and fabrication processes of a wave cooling system for microchip cooling applications are explained. When designing the system, the design of experiments was used to optimize four design parameters. Using the optimized values, a prototype cooler was fabricated that could work with a 385 Hz frequency, and a performance test was conducted. Consequently, when a 1.5 V voltage was applied with an insulation condition, ΔT=8.5°C and 5.0°C cooling were achieved. Finally, the cooling power was calculated, which showed the ability of 0.125 W. Based on these results, it is believed that the developed wave cooling system will be applicable in microchip cooling. © 2021 The Korean Society of Mechanical Engineers.
