    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.
