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 method includes creating Coriolis-based deflection in at least one oscillating flow tube of a flow meter, which is caused by material flowing through the at least one flow tube. The method also includes determining a deflection amplitude and deflection period using interferometric measurements. The method further includes determining a characteristic of the material using the amplitude and period and transmitting the characteristic. A laser interferometer could include a photo-detector. The deflection period could be based on variations in a period of fringes in the photo-detector's output. The deflection amplitude could be based on a number of fringes during the deflection period. A resonant frequency of the at least one flow tube can be determined using the deflection period, and a density of the material can be determined using the resonant frequency. The characteristic of the material could include a mass flow rate or a volumetric flow rate of the material.

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.
