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. The adhesive support structure has at least one lateral dimension defined by a trench in the cooling element or the bottom plate.

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 cooling system is described. The cooling system includes a support structure, a cooling element, and drive electronics. The cooling element has a central axis and is supported by the support structure at the central axis. First and second portions of the cooling element are on first and second sides of the central axis and unpinned. The first and second portions of the cooling element undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure. The cooling element further has first and second piezoelectrics having opposite polarizations. The first piezoelectric is part of the first portion of the cooling element. The second piezoelectric is part of the second portion of the cooling element. The drive electronics drive the first and second portions of the cooling element using a single drive signal.

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.
