Abstract: A mobile device, such as a mobile phone, including a housing and active cooling cells is described. The active cooling cells are in the housing. The cooling cells utilize vibrational motion to drive a fluid such that the mobile phone has a coefficient of thermal spreading (CTS) greater than 0.5 for a steady-state power generated by the mobile phone of at least five watts.

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 cooling system and method for using the cooling system are described. The cooling system includes an array of cooling elements and a controller. The array of cooling elements corresponds to regions of the heat-generating structure where heat is generated in response to operation of the semiconductor. The controller is configured to activate portions of the array of cooling elements based on a determination that operation of the heat-generating structure is likely to generate heat in a given region of the heat-generating structure.

Abstract: A cooling system including a support structure and a cooling element are described. The cooling element has a central region, a first cantilevered arm, a second cantilevered arm, and a piezoelectric. The cooling element is supported by the support structure at the central region. The piezoelectric extends across at least half of a length of the first cantilevered arm. The first and second cantilevered arms are configured to undergo vibrational motion when actuated to drive a fluid toward a heat-generating structure.

Abstract: A cooling system including a support structure, a cooling element, and a bottom plate is described. The cooling element has a central region and a perimeter. The cooling element is supported by the support structure at the central region. At least a portion of the perimeter is unpinned. The cooling element undergoes vibrational motion when actuated to drive a fluid toward a heat-generating structure. The bottom plate has orifices and at least one cavity therein. The at least one cavity is adjacent to and fluidically connected with the orifices. The at least one cavity and the orifices define an orifice distance between the orifices and the heat-generating structure and an orifice length within the bottom plate. The heat-generating structure and the bottom plate define a gap between a portion of the bottom plate and a portion of the heat-generating structure.

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).
