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: An actuator usable in a cooling system is described. The actuator includes an anchored region and a cantilevered arm. The cantilevered arm extends outward from the anchored region. The cantilevered arm includes a step region, an extension region and an outer region. The step region extends outward from the anchored region and has a step thickness. The extension region extends outward from the step region and has an extension thickness less than the step thickness. The outer region extends outward from the extension region and has an outer thickness greater than the extension thickness.

Abstract: A system including an active cooling system is described. The active cooling system includes a cooling element in communication with a fluid and configured to use vibrational motion to direct a fluid toward a surface of heat-generating structure(s). Heat is transferred from the heat-generating structure to the fluid. The system is configured such that the fluid follows a path from the surface of the heat-generating structure(s) past a structure having a lower temperature than the surface of the heat-generating structure. The structure absorbs heat from the fluid. The structure is within the system and distal from the active cooling system.

Abstract: An active cooling system is described. The active cooling system includes at least one cooling element that has a vent therein and is in communication with a fluid. The cooling element(s) are actuated to vibrate to drive the fluid toward a heat-generating structure and to alternately open and close at least one virtual valve corresponding to the vent. The virtual valve is open for a low flow resistance and closed for a high flow resistance. The vent remains physically open for the virtual valve being closed.

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 cooling element and an egress passageway is described. The cooling element is configured to provide a stream of hot air having been heated by a heat from a heat-generating structure. The hot air passes through the egress passageway toward an egress. The egress passageway includes at least one inlet through which cool air is drawn to be mixed with the hot air.
