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.

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 heat transfer system includes fluid transfer cells that vibrationally move a fluid and a thermally conductive cover that conducts heat from the cells while avoiding transfer of mechanical energy between the cells. A fluid transfer module includes outer and inner walls, a support member, and a membrane. The outer wall has an outer opening. The inner wall has an inner opening. The support member is disposed laterally on the inner wall such that a flow chamber is defined between the outer and inner walls. The membrane is supported by the support member along the outer wall. A fluid transfer module includes an inlet port and an actuator. The actuator undergoes vibrational motion and has first and second vibrational modes. The first vibrational mode causes fluid to enter the inlet port. The second vibrational mode expels fluid from the inlet port, which reduces clogging of the inlet port.
