Abstract: A method for providing a cooling system is described. The method includes providing a plurality of sheets. Each sheet includes at least one structure for a level in each cooling cell of a plurality of cooling cells. A particular level of each cooling cell includes a cooling element having a first side and a second side. The cooling element is configured to undergo vibrational motion to drive fluid from the first side to the second side. The method also includes aligning the sheets, attaching the sheets to form a laminate that includes the cooling cells, and separating the laminate into sections. Each section includes at least one cooling cell.

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 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 system including at least one heat-generating structure and a cooling system is described. The cooling system includes a cooling element and an exhaust system. The cooling element is in communication with a fluid and is configured to direct the fluid toward the heat-generating structure(s) using vibrational motion. The exhaust system is configured to direct fluid away from the heat-generating structure to extract the heat and/or to draw the fluid toward the cooling element.

Abstract: A cooling system including a support structure and a cooling element is described. The cooling element has a central region and a perimeter. The cooling element is supported by the support structure at the central region. At least a portion of the perimeter is unpinned. The cooling element is configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. Further, the cooling element has a first side distal from the heat-generating structure and a second side proximate to the heat-generating structure. The support structure supports the cooling element from one of the first side and the second side.

Abstract: A cooling system including a support structure and a cooling element are described. The cooling element has a central region, a first cantilevered arm, a second cantilevered arm, and a piezoelectric. The cooling element is supported by the support structure at the central region. The piezoelectric extends across at least half of a length of the first cantilevered arm. The first and second cantilevered arms are configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure.

Abstract: A cooling system including a support structure, a cooling element, and a bottom plate is described. The cooling element has a central region and a perimeter. The cooling element is supported by the support structure at the central region. At least a portion of the perimeter is unpinned. The cooling element undergoes vibrational motion when actuated to drive a fluid toward a heat-generating structure. The bottom plate has orifices and at least one cavity therein. The at least one cavity is adjacent to and fluidically connected with the orifices. The at least one cavity and the orifices define an orifice distance between the orifices and the heat-generating structure and an orifice length within the bottom plate. The heat-generating structure and the bottom plate define a gap between a portion of the bottom plate and a portion of the heat-generating structure.
