A system to extract heat from a high power density device and dissipate heat at a convenient distance. The system circulates liquid metal in a closed conduit using one or more electromagnetic pumps for carrying away the heat from high power density device and rejecting the heat at a heat sink located at a distance. The system may make use of a thermoelectric generator to power the electromagnetic pumps by utilizing the temperature difference between the inlet and outlet pipes of the heat sink. The system also provides networks of primary and secondary closed conduits having series and parallel arrangements of electromagnetic pumps for dissipating heat from multiple devices at a remotely located heat sink.

Cooling of High Power Density Devices Using Electrically Conducting Fluids

A method of protecting an electronics package is discussed along with devices formed by the method. The method involves providing at least one electronic component that requires protecting from tampering and/or reverse engineering. Further, the method includes mixing into a liquid glass material at least one of high durability micro-particles or high-durability nano-particles, to form a coating material. Further still, the method includes depositing the coating material onto the electronic component and curing the coating material deposited.

Embodiments of systems and methods for compressing plasma are described in which plasma pressures above the breaking point of solid material can be achieved by injecting a plasma into a funnel of liquid metal in which the plasma is compressed and/or heated.

A coating for reducing interaction between a surface and the environment around the surface includes an alkali silicate glass material configured to protect the surface from environmental corrosion due to water or moisture. The alkali silicate glass material is doped with a first element to affect various forms of radiation passing through the coating. The electromagnetic radiation is at least one of ultraviolet, x-ray, atomic (gamma, alpha, beta), and electromagnetic or radio wave radiation. The coating may also be used to protect a solar cell from the environment and UV rays while retransmitting received light as usable light for conversion into electrical energy. The coating may also be used to prevent whisker formation in metal finishes of tin, cadmium, zinc, etc.

Alkali silicate glass based coating and method for applying

A circuit board includes a pump and a channel. The channel includes a liquid metal and a coating. The liquid metal is pumped through the channel by the pump and the coating reduces diffusion and chemical reaction between the liquid metal and at least portions of the channel. The liquid metal can carry thermal energy to act as a heat transfer mechanism between two or more locations on the substrate. The substrate may include electrical interconnects to allow electrical components to be populated onto the substrate to form an electronics assembly.

System and method for a substrate with internal pumped liquid metal for thermal spreading and cooling

A method for integrating liquid metal magnetohydrodynamic power generation with fusion blanket technology to produce electrical power from a thermonuclear fusion reactor located within a confining magnetic field and within a toroidal structure. A hot liquid metal flows from a liquid metal blanket region into a pump duct of an electromagnetic pump which moves the liquid metal to a mixer where a gas of predetermined pressure is mixed with the pressurized liquid metal to form a Froth mixture. Electrical power is generated by flowing the Froth mixture between electrodes in a generator duct. When the Froth mixture exits the generator the gas is separated from the liquid metal and both are recycled.

Method and system to directly produce electrical power within the lithium blanket region of a magnetically confined, deuterium-tritium (DT) fueled, thermonuclear fusion reactor

A system for forming a thick flowing liquid metal, in this case lithium, layer on the inside wall of a toroid containing the plasma of a deuterium-tritium fusion reactor The presence of the liquid metal layer or first wall serves to prevent neutron damage to the walls of the toroid A poloidal current in the liquid metal layer is oriented so that it flows in the same direction as the current in a series of external magnets used to confine the plasma This current alignment results in the liquid metal being forced against the wall of the toroid After the liquid metal exits the toroid it is pumped to a heat extraction and power conversion device prior to being reentering the toroid
