A heat sink with shape-optimized fins provides for improved heat transfer. Synthetic jets create vortices which enhance heat transfer and cooling of downstream fins, while the shape of the fins limits pressure drop in the flow over the cooling fins.

Shaped heat sinks to optimize flow

A chassis with distributed jet cooling is provided. The chassis includes one or more sidewalls defining a volume configured to substantially surround one or more heat generating components positioned within the volume. The chassis further includes at least one array of fins thermally coupled to a respective one of the one or more sidewalls and at least one synthetic jet assembly comprising a multi-orifice synthetic jet or a number of single orifice synthetic jets disposed on a side of a respective one of the array(s) of fins. The chassis further includes at least one attachment means for attaching a respective one of the at least one synthetic jet assemblies to a respective one of the one or more sidewalls.

Chassis with distributed jet cooling

A thermal management system is provided. The thermal management system includes at least one heat sink including one or more respective fins, wherein the one or more fins include one or more respective cavities. The thermal management system also includes a synthetic jet stack including at least one synthetic jet mounted within each of the respective cavities employing at least one engaging structure to provide a rigid positioning of the synthetic jet stack within the fins, wherein the synthetic jet includes at least one orifice through which a fluid is ejected.

Thermal management system and method

Lighting systems having a light source and a thermal management system are provided. The thermal management system includes synthetic jet devices, a heat sink and a heat distribution face plate. The synthetic jet devices are arranged in parallel to one and other and are configured to actively cool the lighting system. The heat distribution face plate is configured to radially transfer heat from the light source into the ambient air.
