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 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 cooling system is described. The cooling system includes a support structure, a cooling element, and drive electronics. The cooling element has a central axis and is supported by the support structure at the central axis. First and second portions of the cooling element are on first and second sides of the central axis and unpinned. The first and second portions of the cooling element undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. The cooling element further has first and second piezoelectrics having opposite polarizations. The first piezoelectric is part of the first portion of the cooling element. The second piezoelectric is part of the second portion of the cooling element. The drive electronics drive the first and second portions of the cooling element using a single drive signal.
