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 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 including a module and an egress passageway is described. The module includes a cooling cells, a heat spreader, and a cover including vents therein. The cooling cells are between the heat spreader and the cover. Each of the cooling cells includes a cooling element configured to draw air in through the plurality of vents and drive air out of an aperture between the heat spreader and the cover at a first flow rate. A stream of hot air having been heated by a heat from a heat-generating structure thermally coupled to the heat spreader is thus provided. 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 at a second flow rate to be mixed with the hot air. The second flow rate is greater than the first flow rate.

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.

Abstract: A cooling system including a heat spreader and a cooling element is described. The heat spreader is thermally coupled with a heat-generating structure. The cooling element is in fluid communication heat spreader. The heat-generating structure is offset from the cooling element. The cooling element undergoes vibrational motion when actuated to drive a fluid toward the heat spreader while not directing the fluid directly at the heat-generating structure.

Abstract: A mobile phone is described. The mobile phone includes a cover, a circuit board to which a heat-generating structure is coupled, and a cooling system including active cooling cell(s) and contained by the cover. The cover defines an interior of the mobile phone. The circuit board is within the interior. The heat-generating structure is thermally coupled with the cooling system. The active cooling cell(s) utilize vibrational motion to drive a fluid for transferring heat from the heat-generating structure. At least one of the mobile phone includes an interposer, the cover includes a raised portion, or the mobile phone includes a cavity therein. The interposer is coupled to the circuit board and includes a gap such that a first portion of the cooling system thermally coupled with the heat-generating structure resides within the gap. The raised portion of the cover is such that a second portion of the cooling system resides in the raised portion. The cavity includes the cooling system, separates the cooling system from the interior, and is such that the interior is water resistant.

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).
