    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 system and method for lowering the structural natural frequency of a synthetic jet actuator is disclosed. A synthetic jet actuator is provided that includes a first plate, a second plate spaced apart from the first plate and arranged parallelly thereto, and a spacer element configured to space the first plate apart from the second plate and define a chamber along with the first and second plates. The spacer element includes at least one orifice formed therein such that the chamber is in fluid communication with an environment external to the chamber, and the spacer element is constructed to deform in a bending motion in response to a deflection of at least one of the first and second plates.

    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.
