Abstract: A system includes an active micro-electric mechanical system (MEMS) cooling system and a drive system. The MEMS cooling system includes cooling element(s) that direct fluid toward a surface of heat-generating structure(s) when driven to vibrate by a driving signal having a frequency and an input voltage. The drive system is coupled to the active MEMS cooling system and provides the driving signal. The drive system includes a power source and a feedback controller providing a feedback signal corresponding to a proximity to a resonant state of the at least one cooling element. The drive system adjusts at least one of the frequency and the input voltage based on the feedback signal such that the frequency corresponds to the resonant state of the cooling element(s). The input voltage does not exceed a maximum safe operating voltage for the cooling element(s).

Abstract: A system including an active cooling system is described. The active cooling system includes a cooling element in communication with a fluid and configured to use vibrational motion to direct a fluid toward a surface of heat-generating structure(s). Heat is transferred from the heat-generating structure to the fluid. The system is configured such that the fluid follows a path from the surface of the heat-generating structure(s) past a structure having a lower temperature than the surface of the heat-generating structure. The structure absorbs heat from the fluid. The structure is within the system and distal from the active cooling system.

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 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.
