Abstract

Dissipating heat in a small space is a significant limitation that may cause overheating in electronic devices.  A synthetic jet refers to a cooling system that does not require a fan and instead relies on the intake and ejection of a high-velocity working fluid through a solitary aperture. This process ensures that there is no overall mass flow. This study examined the effect of the volume cavity at varying distances from the nozzle to the heated surface, and at varying frequencies. In this study, three experiments involving heater characteristics, external and internal temperatures, and fluid air velocity for the manufactured synthetic jet were conducted by utilizing a 100-watt, 24-volt heater. The power input was set to achieve a consistent heater surface temperature at 343.15 K. Five different volumes were tested in the range of 300 Hz to 700 Hz driving frequency at a distance of 50 mm between the nozzle and the heated surface. Compared to other driving frequencies, it was observed that 500 Hz in Model 1 (431.75 K) produced the highest cooling effect by reducing the greatest temperature drop. It is assumed that the resonance frequency with the greatest amplitude is 500 Hz. The highest temperature decrease was obtained at a 50 mm distance. The maximum air velocity for each model was measured at 10 mm, while the lowest air velocity was obtained at a 70 mm distance. Model 1 of the synthetic jet produced the highest and lowest air velocity of 1.29 and 0.08 metres per second, respectively.
