  • Publication number: 20140198452
    Abstract: Cooled electronic assemblies and methods of fabrication are provided. In one embodiment, the assembly includes a coolant-cooled electronic module with one or more electronic component(s), and one or more coolant-carrying channel(s) integrated within the module, and configured to facilitate flow of coolant through the module for cooling the electronic component(s). In addition, the assembly includes a coolant manifold structure detachably coupled to the electronic module. The manifold structure facilitates flow of coolant to the coolant-carrying channel(s) of the electronic module, and the coolant manifold structure and electronic module include adjoining surfaces. One surface of the adjoining surfaces includes a plurality of coolant capillaries or passages. The coolant capillaries are sized to inhibit, for instance, via surface tension, leaking of coolant therefrom at the one surface with decoupling of the coolant manifold structure and electronic module along the adjoining surfaces.

  • Patent number: 8713955
    Abstract: Apparatuses and methods are provided for facilitating cooling of an electronic component. The apparatus includes a vapor-compression refrigeration system. The vapor-compression refrigeration system includes an expansion component, an evaporator, a compressor, and a condenser coupled in fluid communication via a refrigerant flow path. The evaporator is coupled to and cools the electronic component. The apparatus further includes a contaminant extractor coupled in fluid communication with the refrigerant flow path. The extractor includes a refrigerant boiling filter and a heater. At least a portion of refrigerant passing through the refrigerant flow path passes through the refrigerant boiling filter, and the heater provides heat to the refrigerant boiling filter to boil refrigerant passing through the filter. By boiling refrigerant passing through the filter, contaminants are extracted from the refrigerant, and are deposited in the refrigerant boiling filter.

  • Publication number: 20140071628
    Abstract: A package structure to implement two-phase cooling includes a chip stack disposed on a substrate, and a package lid that encloses the chip stack. The chip stack includes a plurality of conjoined chips, a central inlet manifold formed through a central region of the chip stack, and a peripheral outlet manifold. The central input manifold includes inlet nozzles to feed liquid coolant into flow cavities formed between adjacent conjoined chips. The peripheral outlet manifold outputs heated liquid and vapor from the flow cavities. The package lid includes a central coolant supply inlet aligned to the central inlet manifold, and a peripheral liquid-vapor outlet to output heated liquid and vapor that exits from the peripheral outlet manifold. Guiding walls may be included in the flow cavities to guide a flow of liquid and vapor, and the guiding walls can be arranged to form radial flow channels that are feed by different inlet nozzles of the central inlet manifold.

  • Patent number: 8600202
    Abstract: An enhanced 3D integration structure comprises a logic microprocessor chip bonded to a collection of vertically stacked memory slices and an optional set of outer vertical slices comprising optoelectronic devices. Such a device enables both high memory content in close proximity to the logic circuits and a high bandwidth for logic to memory communication. Additionally, the provision of optoelectronic devices in the outer slices of the vertical slice stack enables high bandwidth direct communication between logic processor chips on adjacent enhanced 3D modules mounted next to each other or on adjacent packaging substrates. A method to fabricate such structures comprises using a template assembly which enables wafer format processing of vertical slice stacks.
