This result is indicated that good position to temperature dropped greatly is located from the front part of piezoelectric fan to the front of heat sink (L g = -22.5) under fixes distance (H w = 21) from piezoelectric fan to channel also found to provide double piezoelectric fan heat drop effect is equal to single one, however, double piezoelectric fans would provide higher heat dissipation as Counter-phase. Numerical simulation parameter are included Nusselt number (N u), distance between peak of fan blades to front part of heat sink (L g =0, 5, 10, -11.25, -22.5, -33.75, -45), height from center on piezoelectric fan bottom side (H w =10, 16, 21), number of piezoelectric fan (single-fan and twin-fan), phase-shift (in-phase and counter-phase), and numbers (n=10, 14) for heat sink fin. The piezoelectric fan is activated by reversible piezoelectric effect in piezoelectric material, change rectangular channel flow field construction, then it affects heat flow status in advance.
