Abstract: An active cooling system includes at least one cooling element that has a vent therein. The active cooling element 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 when the virtual valve is closed.

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.
