    Abstract: A system for cooling a device includes a heat sink comprising a substrate having a plurality of fins arranged thereon, a fan positioned to direct an ambient fluid in a first direction across the heat sink, and a first synthetic jet assembly comprising one of a multi-orifice synthetic jet and a plurality of single orifice synthetic jets. The first synthetic jet assembly is configured to direct the ambient fluid in a second direction across the heat sink, wherein the second direction is approximately perpendicular to the first direction.

    Abstract: A heat sink with distributed jet cooling is provided. The heat sink includes a base for thermal connection to at least one heated object, an array of fins thermally coupled to the base, and at least one multi-orifice synthetic jet or multiple single orifice jets disposed on a side of the array of fins. A heat sink with distributed and integrated jet cooling is also provided and includes a base and an array of fins. Respective ones of at least a subset of the fins comprise a synthetic jet configured to eject an ambient fluid into an ambient environment of the fins and base. Another heat sink with distributed and integrated jet cooling is provided and includes a base, an array of fins and multiple synthetic jets coupled to respective ones of the fins. The synthetic jets are provided for at least a subset of the fins.

    Abstract: A synthetic jet includes a first backer structure and a first actuator coupled to the first backer structure to form a first composite unit. The synthetic jet also includes a second backer structure, and a second actuator coupled to the second backer structure to form a second composite unit. A wall member is coupled to and positioned between the first and second backer structures to form a cavity. The first composite unit has an orifice formed therethrough and the orifice is fluidically coupled to the cavity and fluidically coupled to an environment external to the cavity.

    Abstract: A method and system for increasing cooling of an enclosure is provided. The component enclosure includes one or more sidewalls defining a volume, the sidewalls are configured to substantially surround a heat generating component positioned within the volume. The component enclosure further includes a synthetic jet assembly positioned adjacent at least one of the sidewalls. The synthetic jet assembly includes at least one synthetic jet ejector having a jet port. The jet port is aligned at least one of perpendicularly, parallelly, and obliquely with a surface of the at least one sidewall. The synthetic jet assembly is configured to direct a jet of fluid through the port at least one of substantially parallel to the surface, perpendicularly onto the surface, and obliquely toward the surface.
