Abstract: An active cooling system and method for using the active cooling system are described. The active cooling system includes a cooling element having a first side and a second side. The first side of the cooling element is distal to a heat-generating structure and in communication with a fluid. The second side of the cooling element is proximal to the heat-generating structure. The cooling element is configured to direct the fluid using a vibrational motion from the first side of the cooling element to the second side such that the fluid moves in a direction that is incident on a surface of the heat-generating structure at a substantially perpendicular angle and then is deflected to move along the surface of the heat-generating structure to extract heat from the heat-generating structure.

Abstract: A cooling system and method for using the cooling system are described. The cooling system includes a plurality of individual piezoelectric cooling elements spatially arranged in an array extending in at least two dimensions, a communications interface and driving circuitry. The communications interface is associated with the individual piezoelectric cooling elements such that selected individual piezoelectric cooling elements within the array can be activated based at least in part on heat energy generated in the vicinity of the selected individual piezoelectric cooling elements. The driving circuitry is associated with the individual piezoelectric cooling elements and is configured to drive the selected individual piezoelectric cooling elements.

Abstract: A cooling system including a heat spreader, an active cooling element, and a base is described. The heat spreader is in thermal communication with a heat-generating structure mounted on a substrate. The heat spreader over hangs the heat-generating structure. The active cooling element is in thermal communication with the heat spreader. The base supports the heat spreader and transfers a load from the heat spreader to the substrate such that a bending of the heat spreader does not exceed ten degrees.

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 for cooling a mobile phone and method for using the system are described. The system includes an active piezoelectric cooling system, a controller and an interface. The active piezoelectric cooling system is configured to be disposed in a rear portion of the mobile phone distal from a front screen of the mobile phone. The controller is configured to activate the active piezoelectric cooling system in response to heat generated by heat-generating structures of the mobile phone. The interface is configured to receive power from a mobile phone power source when the active piezoelectric cooling system is activated.
