Abstract
Cilia-like micro surface actuators are applied to fins of a heat sink to improve heat dissipation. The surface actuators act as active surface features whose motion disrupts the boundary layer fluid flow by entraining cool fluid towards the heat transfer surfaces of the fins and ejecting relatively warmer fluid away from the surfaces. This disruption reduces the thermal resistance between the heat sink fins and the fluid (e.g., the convection resistance). The motion of the surface actuators also induces a net flow along the surface of the fin(s) and can, therefore, be viewed analogously to a “pump” moving fluid (such as air) over the surface. The surface actuators can be fabricated using plastic microelectromechanical systems (MEMS) technology and can be actuated to generate their motion using several techniques.
