摘要： An apparatus includes a plurality of islands each carrying multiple cantilevers. The apparatus also includes a fluidic network having a plurality of channels separating the islands. The channels are configured to provide fluid to the islands, and the fluid at least partially fills spaces between the cantilevers and the islands. Heat from the islands vaporizes the fluid filling the spaces between the cantilevers and the islands to transfer the heat away from the islands while driving the cantilevers into oscillation. The apparatus may also include a casing configured to surround the islands and the fluidic network to create a vapor chamber, where the vapor chamber is configured to retain the vaporized fluid. The islands and the fluidic network could be formed in a single substrate, or the islands could be separate and attached together by a binder located within the channels of the fluidic network.

摘要： A blowerless heat exchanger apparatus based on micro-jet entrainment is disclosed. The heat exchanger apparatus incorporates a number of fins regularly spaced apart from each other and parallel to each other, thus letting air currents flow in the space defined between them. A dense array of micro-jet nozzles can be fabricated on the fins surface pointing to the flow direction of the air movement in order to induce increase airflow. The air from an air compressor delivers sufficient airflow on the fins surface utilizing micro-jets entrainment. The micro-jet entrainment confirms strong turbulent around the micro-jets and suggests significant heat transfer enhancement. The turbulence from the micro-jets enhance the heat transfer coefficient, potentially by an order of magnitude, therefore allowing much larger fin spacing and leads to huge reduction of flow resistance and overall power consumption.

摘要： A radial turbomolecular pump comprising an electrostatically levitated rotor with a high compression ratio and pump speed at a chip-scale level. The levitated rotor can be sandwiched between a stator plate and a driver and multiple concentric rings of microblades can be fabricated on the rotor plate and the stator plate. The center portions of the driver and the base plate include concentric ring electrodes for rotor levitation by electrostatic forces. The space between two concentric rings of microblades forms a groove that is wide enough to receive the microblades from the opposing disk. The stator disk can be fixed and the rotor disk spins such that the rotor microblades move tangentially relative to the stator microblades. The microblades can be tilted at an angle from the tangent, facilitating momentum transfer to gas molecules in the radial direction.

摘要： An entrainment heatsink system and method using distributed micro jets. Such a system and/or method utilize a pressurized primary flow through arrays of micro nozzles to entrain a much larger secondary flow to carry heat away from the heatsink. The bleed air from an aircraft engine represents an ideal pressurized air source for the primary flow with respect to such a heatsink. As such, the needed high-pressure primary flow is very small and can be delivered via thin air hoses, which has the flexibility to reach constraint spaces. In addition to the entrainment effect, the distributed micro jets also induce a high level of turbulence in the heatsink, significantly enhancing heat transfer and cooling performance.
