[0032] General electrohydraulic (EHD) fluid acceleration

[0033] Devices constructed using the principle of ion motion of fluids are known in the literature by various names: ion blowers, electric blowers, corona wind pumps, electro-hydrodynamic (EFD) devices, electrohydrodynamic (EHD) thrusters, and EHD air pumps. Aspects of this technology have also been developed for use in devices known as electrostatic air cleaners or electrostatic precipitators. In general, EHD techniques use the principle of ion flow to propel a fluid (eg, air molecules). The basic principles of EHD fluid flow are well understood by those skilled in the art. Thus, a brief description of ion flow using the corona discharge principle in a simple two-electrode system provides the basis for the detailed description that follows.

[0034] refer to Figure 1A As shown, the EHD principle involves applying a high strength electric field. Fluid molecules in the vicinity of the emitter discharge region 11 , ...

Abstract

Techniques are described for integration of EHD-type air movers with electronic systems, and in particular, for limiting infiltration of ions and / or charged particulates into an internal air plenum. In some designs, it may be desirable to allow or even encourage EHD motivated air flow (whether drawn or forced) through the internal air plenum while providing a barrier to transit of ions and / or charged particulates that may be generated during EHD operation. Such a barrier may employ electrostatic forces to impede transit of ions and / or charged particulate across a vent positioned to allow air flow from or into the internal air plenum.

Description

technical field [0001] The present invention relates generally to the integration of electro-hydraulic (EHD) air movers with electronic systems and, more particularly, to techniques for limiting the infiltration of ions and / or charged particles into internal airflow passages. Background of the invention [0002] Many devices or systems, whether electronic, optical or mechanical, may include, provide or require forced flow of air or other fluids. In some cases, forced flow is used to cool or moderate heat generated by heat sources within a device or system. In such cases, cooling or thermal moderation may help prevent device overheating, reduce thermal hotspots, provide desired thermal stability to temperature sensitive devices, improve long-term reliability, or provide other benefits. In some cases, forced flow may be the primary function of the device or system. [0003] The use of fans, blowers, or other similar mechanically moving devices to provide cooling air flow is ...
