Abstract: A flow chamber having an upper chamber, a lower chamber, and an actuator is described. The upper chamber includes a top wall. The actuator is located distally from the top wall. The lower chamber includes a bottom wall and a sidewall. The lower chamber receives a fluid from the upper chamber when the actuator is activated. The bottom wall has orifices and at least one cavity therein. The orifices are vertically aligned with a portion of the actuator and allow the fluid to exit the lower chamber. The at least one cavity is proximate to the sidewall and distally located from the orifices.

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: A fluid flow system is described. The fluid flow system includes an actuator and a chamber having a feature therein. The actuator is configured to vibrate in response to a driving signal. The chamber is in communication with the actuator. The chamber is characterized by a fluidic resonant frequency. Vibration of the actuator tends to drive a fluid through the chamber. The feature is within the chamber and obstructs direct flow of the fluid within the chamber such that the fluidic resonant frequency is less than a nominal fluidic resonant frequency that would exist without the feature.

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 cooling system is described. The cooling system includes a cooling element having a central region and a perimeter. The cooling element is anchored at the central region. At least a portion of the perimeter is unpinned. The cooling element is in communication with a fluid. The cooling element is actuated to induce vibrational motion to drive the fluid toward a heat-generating structure.

Abstract: A system including a plurality of cooling cells is described. Each of the cooling cells includes a support structure and a cooling element. The cooling element has a central region having an axis and a perimeter. The cooling element IS supported by the support structure at the central region and along the axis. At least a portion of the perimeter being unpinned. The cooling element is configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. A portion of the cooling cells aligned along the axis are physically connected such that the cooling cells form an integrated cooling cell tile.

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.
