ELECTROHYDRODYNAMIC FLUID MOVER TECHNIQUES FOR THIN, LOW-PROFILE OR HIGH-ASPECT-RATIO ELECTRONIC DEVICES

摘要

Surfaces for electromagnetic shielding, retaining electrostatic charge and indeed collecting ion current in EHD fluid mover designs may be formed as or on surfaces of other components and/or structures in an electronic device (e.g., 100, 700, 1000). In this way, dimensions may be reduced and packing densities increased. In some cases, electrostatically operative portions (e.g., 392, 393, 792, 793, 794, 1192, 1193 and/or 1194) of an EHD fluid mover (e.g., 110, 310, 710, 910, 1010A, 1010B) are formed as or on surfaces of an enclosure, an EMI shield, a circuit board and/or a heat pipe or spreader. Depending on the role of these electrostatically operative portions, dielectric, resistive and/or ozone robust or catalytic coatings or conditioning may be applied.
