    Abstract: The present invention provides a proportional microvalve (10) having a first (12), second (14) and third layer (16), and having high aspect ratio geometries. The first layer (12) defines a cavity (24) with inlet (20) and outlet (22) ports. The second layer (14), doped to have a low resistivity and bonded between the first (12) and third (16) layers, defines a cavity (24) having a flow area to permit fluid flow between the inlet (20) and outlet (22) ports. The second layer (14) further defines an actuatable displaceable member (26), and one or more thermal actuators (28, 30) for actuating the displaceable member (26) to a position between and including an open and a closed position to permit or occlude fluid flow. The third layer (16) provides one wall of the cavity (24) and provides electrical contacts (32a, 32b, 34a, 34b) for electrically heating the thermally expandable actuators (28, 30). The thermal actuators (28, 30) and the displaceable member (26) have high aspect ratios and are formed by deep reactive ion etching such that they are displaceable in the plane of the second layer (14) while being very stiff out of the plane. Thus, both actuation and displacement of the displaceable member (26) are in the plane of the layer.

    Abstract: Briefly described, the present invention is concerned with cooling heating bodies and/or heated fluid with synthetic jet actuators (10) in either open or closed systems. A first preferred embodiment of a cooling system of the present invention comprises a synthetic jet actuator directed to impinge directly on a heat producing (or heated) body. The synthetic jet actuator generates a synthetic jet stream (152) comprised of cool ambient fluid that impinges on the heated surface thereby cooling this surface. As an example, the heated surface/body could be a microchip array (155) in a microcomputer. After coming into contact with the heated surface, the fluid moves along the surface and is finally rejected to the ambient where it mixes and cools down. The synthetic jet may be incorporated into a modular unit that may be clipped onto a circuit board or other heat producing element to provide added, 'ad hoc' cooling. In another configuration, a synthetic jet stream actuator may be positioned, relative to the heated surface. In this embodiment, the flow (612) would be approximately tangential to a surface of heat producing body (608). This embodiment may further comprise a cyclical flow of the fluid jet, along the heated body and about a heat sink surface.
