摘要： A slush hydrogen production device (10) utilizes a hydrogen slushifier magnetic refrigerator (30) having a wheel (50) of material exhibiting the magnetocaloric effect. The wheel is rotated through a magnetic field of varying intensity around the circumference of a wheel housing (36) created by the windings of superconductive magnets (56). The material of the wheel (50) follows a magnetic Carnot cycle as the wheel rotates (36) through regions of low temperature heat transfer and high temperature heat transfer. Liquid hydrogen is supplied to the regions of low and high temperature heat transfer through inlet pipes (39 and 42). Gaseous hydrogen is produced in the high temperature heat transfer region and vented away by an outlet pipe (48). Solid hydrogen is produced in the low temperature heat transfer region by direct solidification upon the magnetic wheel (50); and is removed by scrapers (76) and deposited in a compartment (26) where it mixes with liquid hydrogen to form slush hydrogen. A second magnetic refrigerator (108) may be used to keep its magnets and the magnets of the hydrogen slushifier magnetic refrigerator (30) at a temperature region suitable to maintain superconductivity. The slush hydrogen production device (10) may be part of a larger operating system that includes a liquid hydrogen storage tank (146), a slush hydrogen storage tank (136), a slush conditioner (148) and appropriate connective plumbing.

摘要： The invention relates to a novel cooling system (100) in which waste heat to be dissipated is first absorbed by an electron emission layer (15). The heat induces a discharge of electrons (13) from the surface of the electron emission layer, whereby the electrons are drawn off by a suction electrode (10) which is located on a positive potential located opposite the emission layer (15). The thermal energy carried along by the electrons (13) induce a heat transfer from the electron emission layer (15) to the suction electrode (10). The intensity of the electron flow can be controlled by the bias voltage of a grid (12) which is arranged between the electron emission layer (15) and the suction electrode (10). The surface of the electron emission layer (15) is preferably composed of alkaline earth metals such as barium or cesium.

摘要： Apparatus and methods for performing switching of heat flow in magnetic refrigeration systems are provided. In one embodiment, microelectromechanical (MEM) switches are provided for switching from a heat absorption phase and a heat rejection phase of a magnetic refrigeration cycle. In other embodiments, these MEM switches are replaced by thermoelectric switches. The thermoelectric switches operate such that an “on” state is defined as heat flow being allowed by virtue of the thermal conductivity of the thermoelectric switch. An “off” state is defined as a net zero heat flow through the thermoelectric switch obtained by providing a current that is just sufficient to offset the heat flow through the thermoelectric switch due to its thermal conductivity. In some embodiments, the thermoelectric switches are “directly coupled” thermoelectric switches, meaning that they are energized by a direct electrical coupling to a current source. In other embodiments, one or more of the thermoelectric switches are “inductively coupled” thermoelectric switches, meaning that they are energized indirectly by a magnetic coupling. The magnetic refrigeration system may be cascaded or paralleled to provide greater cooling.

摘要： A fluid conduit includes a hollow inner tube which is made of a heat-conducting material and which confines a first chamber, and a hollow outer tube which is made of a heat-conducting material, which is disposed concentrically around the inner tube, and which cooperates with the inner tube to form a second chamber. One of the first and second chambers is adapted to permit passage of fluid therethrough. The other one of the first and second chambers has opposing closed ends, and is filled with a superconductor material so as to provide the fluid conduit with an enhanced thermal conducting ability.

摘要： A method and apparatus is provided for generating an artificial heat sink below ambient temperature for a cryogenic condenser by isothermally magnetizing a paramagnetic fluid and removing the magnetic field thereby creating a temperature drop in the fluid by the magentocaloric effect. The heat of magnetization is converted into mechanical work by initially placing the fluid inside a sealed chamber with a door that opens to a conduit leading into the bore of a superconducting solenoid. When the solenoid is energized with current, it creates a strong axial magnetic field that exerts magnetic attractive forces on the fluid inside the chamber. When the fluid is released by opening the door, it is accelerated through the conduit toward the superconducting solenoid where it becomes magnetized by the increasing strength of the magnetic field. By mounting a non-magnetic turbine inside the conduit between the solenoid and the chamber, the kinetic energy of the accelerating flow stream, which is equal to the heat of magnetization, is converted into mechanical work thereby achieving isothermal magnetization. By removing the magnetic field after the fluid enters the bore of the solenoid, a temperature reduction is achieved thereby enabling the fluid to absorb heat in a cryogenic condenser.
