Apparatus and method are provided for reducing acoustical noise when cooling a device, such as a lamp system. The apparatus includes at least a set of a first synthetic jet and a second synthetic jet. The first and second synthetic jets are responsive to respective actuating signals having a phase difference (e.g., 180°) between one another chosen to reduce acoustic noise produced by the first and second synthetic jets when cooling the device.

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.

A heat exchange assembly for treating carbon dioxide (CO2) is described. The heat exchange assembly includes a housing that includes an inlet, an outlet, and an inner surface that defines a cavity extending between the inlet and the outlet. The housing is configured to receive solid CO2 through the inlet. At least one heat exchange tube extends through the housing. The heat exchange tube is oriented to contact solid CO2 to facilitate transferring heat from solid CO2 to a heat exchanger fluid being channeled through the heat exchange tube to facilitate converting at least a portion of solid CO2 into liquid CO2. The heat exchange assembly is configured to recover a refrigeration value from the solid CO2 and transfer at least a portion of the recovered refrigeration value to a flue gas.

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.

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.

Disclosed is a system for cooling an electronics package. The system includes a fluid pump and a microcooler assembly. The system utilizes one or more cooling layers interspersed with layers of electronics in the electronics package. Each cooling layer has an array of cooling channels formed in a substrate, an input manifold through which cooling fluid is provided for distribution through the array of cooling channels, and an output manifold which collects fluid from the array of cooling channels. The elements of the cooling system are integrated by conduits including a package conduit for passage of fluid from the fluid pump to the electronics package, a cooler conduit for passage of fluid from the electronics package to the microcooler assembly, and a pump conduit for passage of fluid from the microcooler assembly to the fluid pump. Also disclosed is a method for cooling the electronics package.
