  • Patent number: 10006571
    Abstract: Conduit connectors for liquid manifolds and methods of fabrication are provided. In one embodiment, a conduit connector is integrated, at least in part, within a liquid manifold, and includes a conduit-receiving opening or socket and at least one releasable retention component. The conduit-receiving opening is disposed within the liquid manifold and in fluid communication with at least one liquid-carrying channel of the liquid manifold. The releasable retention component(s) is selectively operative to threadlessly secure in a fluid-tight manner a conduit within the conduit-receiving opening in fluid communication with the at least one liquid-carrying channel of the liquid manifold to facilitate flow of liquid through the liquid-carrying channel(s), or to release the conduit from the conduit-receiving opening of the conduit connector. The releasable retention component(s) resides at least partially within the liquid manifold when operatively holding the conduit within the conduit-receiving opening.

The IC chip is concentrically arranged within the opening of the stiffening frame. The first directional heat spreader is attached to the stiffening frame and to the IC chip and generally removes heat in a first opposing bivector direction. When included in the IC chip module, the second directional heat spreader is attached to the stiffening frame and to the first directional heat spreader and generally removes heat in a second opposing bivector direction orthogonal to the first opposing bivector direction.

  • Patent number: 9568960
    Abstract: A semiconductor structure includes a substrate with cooling layers, cooling channels, coolant inlets and outlets in fluid communication with the cooling channels, and a device layer on the cooling layers with one or more connection points and a device layer area. The device layer thermal coefficient of expansion is substantially equal to that of the cooling layers. A plurality of laminate substrates are disposed on, and electrically attached to, the device layer. The laminate substrate thermal coefficient of expansion differs from that of the device layer, each laminate substrate is smaller than the device layer portion to which it is attached, and each laminate substrate includes gaps between sides of adjacent laminate substrates. The laminate substrates are not electrically or mechanically connected to each other across the gaps therebetween and the laminate substrates are small enough to prevent warping of the device, interconnection and cooling layers due to thermal expansion.

  • Patent number: 9470439
    Abstract: Apparatuses and methods are provided for facilitating cooling of an electronic component. The apparatus includes a vapor-compression refrigeration system, which includes an expansion component, an evaporator, a compressor and a condenser coupled in fluid communication. The evaporator is coupled to and cools the electronic component. The apparatus further includes a contaminant separator coupled in fluid communication with the refrigerant flow path. The separator includes a refrigerant cold filter and a thermoelectric array. At least a portion of refrigerant passing through the refrigerant flow path passes through the cold filter, and the thermoelectric array provides cooling to the cold filter to cool refrigerant passing through the filter. By cooling refrigerant passing through the filter, contaminants solidify from the refrigerant, and are deposited in the cold filter.

  • Patent number: 9437515
    Abstract: Embodiments of the invention comprise a homogeneous heat spreading cap element in chip packages to facilitate better heat spreading and dissipation. The heat spreading cap comprises a single high-K graphite layer supported by a copper frame for increased stability and reduced thermal warpage during handling and operation while minimizing thermal penalty by reducing the amount of material having a relatively low heat conductivity that is needed in conventional heat spreading caps.
