Abstract: A cooling system is described. The cooling system includes a bottom plate, a support structure, and a cooling element. The bottom plate has orifices therein. The cooling element has a central axis and is supported by the support structure at the central axis. A first portion of the cooling element is on a first side of the central axis and a second portion of the cooling element is on a second side of the central axis opposite to the first side. The first and second portions of the cooling element are unpinned. The first portion and the second portion are configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. The support structure couples the cooling element to the bottom plate. At least one of the support structure is an adhesive support structure or the support structure undergoes rotational motion in response to the vibrational motion.

Abstract: A heat transfer system including an active component and a dissipation region is described. The active component is configured to undergo vibrational motion. The active component transfers fluid from a high pressure region to an ambient pressure region via an egress. The active component also induces a pulsating pressure in the fluid. The pulsating pressure is dissipated in the dissipation region such that turbulence is reduced where the fluid is introduced to the ambient pressure region.

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 a tile and a hood is described. The tile includes a plurality of cooling cells. Each of the cooling cells includes a support structure and a cooling element. The cooling element is supported by the support structure and is configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. The hood is coupled to the tile and directs the fluid around the plurality of cooling cells.
