Abstract

In this study, a horizontal piezoelectric fan is used to realize forced convection in a pin-fin heat sink. In addition, the resulting forced convection flow field is investigated using numerical simulation methodologies (ANSYS CFD/Fluent). The swinging of the piezoelectric fan caused by the inverse piezoelectric effects of the piezoelectric materials actualized the movement of the thin fin and convection of the surrounding fluid, resulting in heat dissipation. The piezoelectric fan exhibited several advantages, including miniaturization, low energy consumption, and low noise. As the distance from the fore-end of the horizontal piezoelectric fan to that of the radiator remained constant (L_g = 5 mm), the heat dissipation efficiency of the pin-fin heat sink increased with the distance from the center of the piezoelectric fan to the baseboard (H_w). This was attributed to the impinging jet generated by the swinging of the piezoelectric fan. The optimal parameters for heat dissipation within the pin-fin heat sink were demonstrated to be L_g = 5 mm and H_w = 30 mm.
