    摘要: 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.

    摘要: 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.
