Abstract
A cooling device comprises a heat sink having fins and a piezofan having a piezoelectric element attached to a planar body. The planar body is capable of oscillating at a movable end in response to applying alternating electric current to the piezoelectric element, thereby generating an air flow toward an output of the cooling device. A plurality of fins is located between the movable end of the planar body and the output end of the cooling device. Each fin has a planar form with a main surface being substantially aligned with the air flow. A cooling assembly comprising such cooling device is also disclosed.
