Abstract: An electronic assembly is provided having a thermal cooling fluid, such as a liquid, for cooling an electronic device within a sealed compartment. The assembly includes a housing generally defining a sealed fluid compartment, an electronic device disposed within the housing and a cooling liquid for cooling the electronic device. The assembly includes inlet and outlet ports in fluid communication with the sealed fluid compartment for allowing the cooling liquid to pass through the compartment to cool the electronic device. Fluid flow channels are formed in thermal communication with the electronic device within the housing. The fluid channels include channels that allow liquid to flow in thermal communication with the electronic device to cool the device.

Abstract: A fluid-cooled electronic assembly including a base having a fluid inlet and a fluid outlet therein, a cap attached to the base to form a fluid containment chamber therebetween, wherein the fluid containment chamber is in fluid communication with the fluid inlet and the fluid outlet, and an electronic device disposed within the fluid containment chamber and connected to the base, the electronic device having a plurality of microchannels adapted to receive a cooling fluid flow therethrough, wherein the cap is shaped to direct a fluid flow from the fluid inlet to the microchannels such that a pressure drop between the fluid inlet and the fluid outlet is reduced.

Abstract: The present invention provides a method for producing an electronic assembly and an electronic assembly with an integrated cooling system for dissipating heat. The electronic assembly comprises a base; and at least one electrical component attached to the base. The base defines an integrated cooling system having a fluid channel spanning within the base and at least one heat exchanger in heat communication with the fluid channel. The integrated cooling system may further include a pump attached to the base for directing the flow of the fluid within the fluid channel, and a port in fluid communication with the fluid channel for receiving fluid from an external source.

Abstract: A power semiconductor device package utilizes integral fluid conducting micro-channels, one or more inlet ports for supplying liquid coolant to the micro-channels, and one or more outlet ports for exhausting coolant that has passed through the micro-channels. The semiconductor device is mounted on a single or multi-layer circuit board having electrical and fluid interconnect features that mate with the electrical terminals and inlet and outlet ports of the device to define a self-contained and self-sealed micro-channel heat exchanger.

Abstract: A package and packaging method that incorporates multiple surface-mounted devices mounted to the package, which in turn can be mounted onto a circuit board. The package generally includes a pair of laminate substrates that together form a chip carrier and input/output (I/O) interface structure for the devices. The devices are mounted to opposite surfaces of a first of the substrates. The second substrate is attached to the first substrate, and has an interior opening therethrough. The first and second substrates are attached to each other such that devices mounted on one surface of the first substrate are disposed within the interior opening of the second laminate substrate. A mold compound can be applied to underfill and encapsulate the devices mounted to the surfaces of the first substrate.

Abstract: The present invention relates to an apparatus and method for dissipating heat from high-power electronic devices. The assembly includes a high-current substrate, such as a printed circuit board supporting an electronic device, a heat pipe thermally coupled with the electronic device and an assembly case which also forms a heat sink, and thermal transient suppression material which may be thermally coupled with the electronic device and the heat pipe.
