A flexible interconnect structure allows for rapid dissipation of heat generated from an electrical device that includes light-emitting elements, such as light-emitting diodes (“LEDs”) and/or laser diodes. The flexible interconnect structure comprises: (1) at least one flexible dielectric film on which circuit traces and, optionally, electrical circuit components are formed and at least a portion of which is removed through its thickness; and (2) at least a heat sink attached to one surface of the flexible dielectric film opposite to the surface on which circuit traces are formed. The flexible interconnect structure can include a plurality of such flexible dielectric films, each supporting circuit traces and/or circuit components, and each being attached to another by an electrically insulating layer. Electrical devices or light sources having complex shapes are formed from such flexible interconnect structures and light-emitting elements attached to the heat sinks so to be in thermal contact therewith.

A micro-electromechanical (MEM) synthetic jet actuator includes a semiconductor substrate having a cavity extending therethrough, such that a first opening is formed in a first surface of the semiconductor substrate and such that a second opening is formed in a second surface of the semiconductor substrate. A first flexible membrane is formed on at least a portion of the front surface of the semiconductor substrate and extends over the first opening. The first flexible membrane also includes an orifice formed therein aligned with the first opening. The MEM synthetic jet actuator also includes a second flexible membrane that is formed on at least a portion of the second surface of the semiconductor substrate and that extends over the second opening, and a pair of actuator elements coupled to the flexible membranes and aligned with the cavity to selectively cause displacement of the first and second flexible membranes.

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.
