  • Patent number: 8885329
    Abstract: When testing or powering up a magnet in a magnetic resonance imaging device, a switch is provided that switches a winding between resistive and superconductive modes. The switch includes a housing that contains a winding wound about a bobbin, and an internal coolant cavity that contains coolant that cools the winding, A baffle separates the internal coolant cavity from an external coolant reservoir. The baffle has small apertures that permit influx of liquid coolant into the internal cavity to cool the winding, At high temperatures, the coolant in the internal cavity vaporizes causing the winding to further increase its temperature and resistance, Upon reduction of heat to the winding, the winding cools sufficiently to permit influx of liquid coolant, thereby restoring a superconductive mode of operation to the winding.

  • Publication number: 20140321057
    Abstract: Various techniques are employed alone or in combination, to reduce the levelized cost of energy imposed by a power plant system. Solar energy concentrators in the form of inflated reflectors, focus light onto photovoltaic receivers. Multiple concentrators are grouped into a series-connected cluster that shares control circuitry and support structure. Individual concentrators are maintained at their maximum power point via balance controllers that control the flow of current that shunts this series connection. DC current from clusters is transmitted moderate distances to a centralized inverter. The inductance of transmission lines is maximized using an air-spaced twisted pair, enhancing the performance of boost-type three phase inverters. Cluster outputs are separate from individual inverters in massively interleaved arrays co-located at a central location.

  • Publication number: 20140293542
    Abstract: The invention is for an apparatus and method for removal of waste heat at high-flux from electronic, photonic, and other components. The apparatus of the present invention is a self-contained unit comprising a closed flow loop flowing liquid metal coolant pumped by an integral magneto-hydrodynamic (MHD) pump. Liquid metal coolant flow is arranged to impinge onto a thin member mounting a heat load. Impinging flow of liquid metal coolant offers a high heat transfer coefficient, which translates to comparably low thermal resistance between the heat load and the liquid metal coolant. As a result, the apparatus may remove heat from the heat load at very high flux. Waste heat acquired from the heat load may be transferred at reduced flux into a flowing secondary coolant, heat pipe, structure, or a radiation panel. Temperature of the heat load may be varied by varying the MHD pump drive current.

  • Patent number: 8830672
    Abstract: A computer system includes a rack-mountable server unit with a closed server housing. The server housing has a channel with a recessed channel wall in conductive thermal communication with a processor or other heat-generating component. An elongate conduit is received into the channel of the server housing in conductive thermal communication with an external surface of the server housing. The server is cooled by conductive fluid flow through the conduit, with no appreciable airflow through the server housing. The system may be operated in an optional burst cooling mode, wherein a volume of cooling fluid is trapped in the conduit for a period of time before being quickly released.

  • Patent number: 8824147
    Abstract: This invention relates to a fluid-cooled electronic equipment item, an avionic rack to receive such an equipment item and an aircraft equipped with such racks. The electronic equipment items are connected to the avionic rack on the one hand electrically (C3-C4) and on the other hand fluidically (36?-37, 45?-44) to a system of pipes (30a, 30b) on at least one cold source for a cooling fluid (30). A heat-dissipating electronic board (35) is equipped with a dissipated-heat collector plate (61-65), in which fluid circulation channels are implemented, connected via quick-disconnect fluidic couplings (42, 39) to quick-disconnect fluidic couplings of the system of pipes. These devices allow the equipment to be removed from or inserted into the rack (32-EE) or the electronic board (35) to be removed from or inserted into the electrical equipment (33-35).

  • Patent number: 8820113
    Abstract: To reduce power consumption and more efficiently cool computing devices in a data center, an air supply unit supplies air from outside the data center to an air handling unit, which cools servers within the data center using the supplied air. Using air from outside the data center, rather than recirculating and cooling air from within the data center, reduces the power consumption of the data center. In an embodiment, a chiller and/or an evaporative cooling system are coupled to the air supply unit to allow further cooling of the outside air before it is circulated. Heat generated by the servers within the data center is collected, for example using thermal pathways coupled to server components, and used by the chiller in an absorption or adsorption process to further reduce power consumption of the data center and allow the air handling unit to further cool the outside air.

The cooling body is cooled by introducing a fluid therein via an input conduit. The hot fluid is received from the cooling body by an output conduit and is cooled for recycling. The housing of the electronic device includes a rearward gap that admits the cooling body into the housing of the electronic device. Preferably, further cooling is provided by forcing a gas to flow past the output conduit.
