Abstract: A system includes an active micro-electric mechanical system (MEMS) cooling system and a drive system. The MEMS cooling system includes cooling element(s) that direct fluid toward a surface of heat-generating structure(s) when driven to vibrate by a driving signal having a frequency and an input voltage. The drive system is coupled to the active MEMS cooling system and provides the driving signal. The drive system includes a power source and a feedback controller providing a feedback signal corresponding to a proximity to a resonant state of the at least one cooling element. The drive system adjusts at least one of the frequency and the input voltage based on the feedback signal such that the frequency corresponds to the resonant state of the cooling element(s). The input voltage does not exceed a maximum safe operating voltage for the cooling element(s).

Abstract: A system including a plurality of cooling cells and a switching and control module is described. The cooling cells including cooling elements configured to be actuated to induce vibrational motion to drive a fluid toward a heat-generating structure. The switching and control module is coupled to the cooling elements and provides drive signals to the cooling elements based on at least one drive signal input. Each of the drive signals has a frequency corresponding to a cooling element. The frequency of the drive signal corresponds to a resonant state of the cooling element.

Abstract: A cooling system including a heat spreader, an active cooling element, and a base is described. The heat spreader is in thermal communication with a heat-generating structure mounted on a substrate. The heat spreader over hangs the heat-generating structure. The active cooling element is in thermal communication with the heat spreader. The base supports the heat spreader and transfers a load from the heat spreader to the substrate such that a bending of the heat spreader does not exceed ten degrees.

Abstract: A fluid flow system is described. The fluid flow system includes an actuator and a chamber having a feature therein. The actuator is configured to vibrate in response to a driving signal. The chamber is in communication with the actuator. The chamber is characterized by a fluidic resonant frequency. Vibration of the actuator tends to drive a fluid through the chamber. The feature is within the chamber and obstructs direct flow of the fluid within the chamber such that the fluidic resonant frequency is less than a nominal fluidic resonant frequency that would exist without the feature.
