  • Patent number: 10761577
    Abstract: An apparatus that first and second volumes are fluidly separated by a combination of a first second and a second sections, where the first section is insoluble to a cooling liquid and the second section is soluble to the cooling liquid. In the event of a leak of coolant liquid, the second sections dissolve, forming a fluid path from the first volume to the second volume. The coolant liquid may then escape the first volume in spaces that result from the dissolution of the second sections.

  • Patent number: 10757842
    Abstract: An electrical power conversion apparatus is provided which includes a semiconductor module and a plurality of cooling pipes. Each of the cooling pipes has an electrical conductivity and a cooling medium flow path formed therein. Each of the cooling pipes is equipped with a flow path extension forming portion which protrudes above a module body in at least one of height-wise directions and in which a portion of the cooling medium flow path is formed. The flow path extension forming portion overlaps at least either of the power terminals or the control terminals in a stacking direction of the cooling pipes. This enhances the efficiency in decreasing the inductance of the power terminals and/or the control terminals, improves the productivity of the electrical power conversion apparatus, and enables the size of the electrical power conversion apparatus to be reduced.

  • Patent number: 10749394
    Abstract: The invention relates to an electrical conductor which is made up substantially of one or even several metal conductors which are sheathed by a graphene layer. Particularly in the case of the electrical conductor transporting an alternating current, the current in the conductor is forced radially outwards and therefore flows in the graphene layer. Since graphene has a substantially better conductivity than the materials customary in this application, such as copper for example, relatively low losses are accordingly produced and substantially higher degrees of efficiency can be achieved. The electrical conductor constructed in this way is used in a stator and/or rotor winding of an electrical machine, so that it has a significantly elevated power-to-weight ratio.

    Abstract: A method of installing an electrically-heatable subsea flowline includes launching the flowline with at least one electric power cable attached in piggybacked relation. After landing the flowline with the piggybacked cable on the seabed, a free end portion of the, or each, cable having a length greater than the water depth is released from the flowline. This allows a free end of the, or each, cable to be recovered to the surface to be spliced to one or more power supply conductors. After lowering the, or each, cable and the, or each, connected conductor beneath the surface, the free end portion of at least one cable is reattached to the flowline on the seabed in piggybacked relation. To perform the method, a subsea flowline assembly includes subsea-releasable fastenings spaced along the cable and the flowline to attach at least an end portion of the cable releasably to the flowline.

As the fluid heats up, it may change phase from a liquid to a gas. The hot gas may rise to a heat-exchanging condenser configured to dissipate the heat and condense the fluid back into a liquid. The cool, condensed liquid my return from the heat-exchanging condenser to the cooling tube. Risers, gas transport tubes, pressure regulation systems, fluid storage tanks, and other components described herein may increase the efficiency of the cooling system and/or otherwise improve the viability of the cooling system for subterranean power lines.

  • Patent number: 8807204
    Abstract: A system for cooling a heat generating device comprises a heat sink and a plurality of ion emitter elements that form an electrohydrodynamic (EHD) air flow device. The heat sink has a base disposed in thermal communication with a heat generating device, such as a processor. A plurality of heat sink fins is coupled to electrical ground to form ion collectors. Ion emitter elements are disposed in a non-planar pattern along first ends of the plurality of fins so that each ion emitter element is equidistant from the first end of a nearest fin. A power supply applies an electrical potential between the plurality of ion emitter elements and the plurality of fins to induce a flow of ions that cause airflow across the heat sink.
