| Summary: | Electronic cooling is constrained by space, which makes it difficult to remove heat that might cause the device to overheat. A synthetic jet is a type of air-based cooling technology that works without the usage of fans. Synthetic jets have zero-net-mass flux as it takes in and discharge high-velocity working fluid from a single outlet. This research analyzed the effect of a volume chamber at various distances between the nozzle and the heated surface. During the investigation, three experiments were carried out: heater characteristic, heated surface temperature, and fluid air velocity for the fabricated synthetic jet. The experiment used a heater with a voltage of 24 V and a power of 100 W. The constant heater surface temperature of 343.15 K was determined using the power input. In this research, five different volumes were tested. Each volume was tested at a distance from 10 to 50 mm between the nozzle and the heated surface. Results show that a t 50 mm distance, the maximum temperature decrease was recorded for 1 mm volume. The maximum air velocity for all synthetic jet models was found at a distance of 10 mm, while the minimum air velocity was found at a distance of 70 mm. The maximum air velocity is produced by lower volume of synthetic jet 1.29 m/s. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
