Abstract:
1. An electronic device comprising: a targeted area within the electronic device, wherein the targeted area includes a first side and a second side different from the first side; a first fan lying along the first side, oriented to cause a first fluid flow; and a second fan lying along the second side, oriented to cause a second fluid flow; wherein the first side and the second side lie along substantially opposite sides of the targeted area and the first fluid flow is substantially parallel but opposed to the direction of the second fluid flow; wherein the first fan and the second fan are both inlet fans; a third fan and a fourth fan, wherein: the targeted area has a third side and a fourth side substantially opposite the third side; the third side and the fourth side are substantially perpendicular to the first side and the second side; the third fan lies along the third side; the fourth fan lies along the fourth side; and the respective fluid flow caused by each fan converges to create a turbulent flow across the targeted area.
