摘要： An electrohydrodynamic fluid accelerator includes an emitter electrode and leading surfaces of a collector electrode that are substantially exposed to ion bombardment. Heat transfer surfaces downstream of the emitter electrode along a fluid flow path include a first portion not substantially exposed to the ion bombardment that is conditioned with a first ozone reducing material. The leading surfaces of the collector electrode are not conditioned with the first ozone reducing material, but may include a different surface conditioning. The downstream heat transfer surfaces and the leading surfaces can be separately formed and joined to form the unitary structure or can be integrally formed. The electrohydrodynamic fluid accelerator can be used in a thermal management assembly of an electronic device with a heat dissipating device thermally coupled to the conditioned heat transfer surfaces.

摘要： In thermal management systems that employ EHD devices to motivate flow of air between ventilated boundary portions of an enclosure, it can be desirable to have some heat transfer surfaces participate in electrohydrodynamic acceleration of fluid flow while providing additional heat transfer surfaces that may not. In some embodiments, both collector electrodes and additional heat transfer surfaces are thermally coupled into a heat transfer path. Collector electrodes then contribute both to flow of cooling air and to heat transfer to the air flow so motivated. The collector electrodes and additional heat transfer surfaces may be parts of a unitary, or thermally coupled, structure that is introduced into a flow path at multiple positions therealong. In some embodiments, the collector electrodes and additional heat transfer surfaces may be proximate each other along the flow path. In some embodiments, the collector electrodes and additional heat transfer surfaces may be separate structures.

摘要： Performance of an electrohydrodynamic fluid accelerator device may be improved and adverse events such as sparking or arcing may be reduced based, amongst other things, on electrode geometries and/or positional interrelationships of the electrodes. For example, in a class of EHD devices that employ a longitudinally elongated corona discharge electrode (often, but not necessarily, a wire), a plurality of generally planar, collector electrodes may be positioned so as to present respective leading surfaces toward the corona discharge electrode. The generally planar collector electrodes may be oriented so that their major surfaces are generally orthogonal to the longitudinal extent of the corona discharge electrode. In such EHD devices, a high intensity electric field can be established in the “gap” between the corona discharge electrode and leading surfaces of the collector electrodes.

摘要： An electrohydrodynamic (EHD) air mover is positionable within the enclosure to, when energized, motivate air flow through the enclosure along a flow path between the inlet and outlet ventilation boundaries. Ductwork within the enclosure has cross-sections substantially matched to a cross-section of the EHD air mover. A fan curve-type, pressure-air flow characteristic measured for the EHD air mover in open air substantially overstates mechanical impedance of the EHD air mover to air flow along the flow path between the inlet and outlet ventilation boundaries in that, when the EHD air mover is operably positioned within the enclosure appurtenant to the ductwork, no more than about 50% of the mechanical impedance of the EHD air mover indicated by the measured fan curve-type, pressure-air flow characteristic actually contributes to total mechanical impedance to air flow through the enclosure along the flow path between the inlet and outlet ventilation boundaries.

摘要： Small form-factor ion flow fluid movers that provide electrostatically operative surfaces in a flow channel adjacent to an emitter electrode, but upstream of a collector electrode or electrodes, can shape operative electric fields and influence ion flows in ways that accentuate downstream flow while minimizing upstream ion migration. In some cases, dielectric surfaces (or even electrically isolated conductive surfaces) along a flow channel adjacent to an emitter electrode can be configured to collect and retain an initial population of generated ions and thereafter electrostatically repel further ions. Depending on the configuration of such dielectric or electrically isolated conductive surfaces, these repelling electrostatic forces may dissuade ion migration or flow from sensitive but closely proximate components and/or may shape fields to enhance ion flows in a desired downstream direction.

摘要： In thermal management systems that employ EHD devices to motivate flow of air through an enclosure, spatial distribution of a ventilation boundary may facilitate reductions in flow resistance by reducing average transit distance for cooling air from an inlet portion of the ventilation boundary to an outlet portion. Some thermal management systems described herein distribute a ventilation boundary over opposing surfaces, adjacent surfaces or even a single surface of an enclosure while providing a short, “U” shaped, “L” shaped or generally straight through flow path. In some cases, spatial distributions of the ventilation boundary facilitate or enable enclosure geometries for which conventional fan or blower ventilation would be impractical. In some cases, provision of multiple portions of the ventilation boundary may allow the thermal management system to tolerate blockage or occlusion of a subset of the inlet and/or outlet portions and, when at least some of such portions are non-contiguous spatially-distributed, tolerance to a single cause of blockage or occlusion is enhanced.

摘要： Disclosed herein are apparatuses and methods related to an electrohydrodynamic (EHD) fluid mover that includes emitter and collector electrodes energizable to motivate fluid flow therebetween. Ozone reducing catalyst bearing heat transfer surfaces may be disposed downstream of the emitter electrode in a flow path of the motivated fluid flow. A controller may be configured to, at respective times throughout the operating life of the EHD fluid mover, selectively employ at least one ozone reduction enhancement response selected from a set of responses. One response includes triggering a conditioning mechanism to apply an additional, but at least partially consumable, ozone reducing catalyst to a surface of the emitter electrode.
