A gradient coil system for a magnetic resonance tomography apparatus has a layer structure including a gradient coil layer and a cooling layer. The cooling layer is fashioned as a plate heat exchanger, composed of plates, for cooling the gradient coil layer. In this way, a highly efficient cooling of the gradient coil layer is achieved with a lower structural height compared to conventional tubular configurations.

A fixed stator is arranged around a rotatably mounted rotor in an electric motor that includes at least one cooling unit to which parts of the stator which are to be cooled are thermally coupled by a line system in which a cooling agent circulates according to a thermosyphon effect. The stator parts to be cooled can be arranged in the inner region of a stator housing which is integrated into the line system. The electric motor can be provided with a heating device to maintain the pressure in the inner region when the motor is stopped.

Hermetically encapsulated rotary piston compressor with horizontally disposed, at least partially hollow crankshaft. The lubricating oil is sucked up by a dynamic vacuum created in a compressed gas line, out of an oil sump, by means of an oil suction pipe, and is conveyed together with the compressed gas into the hollow part of the crankshaft, which has inside the cylinder housing radial bores for oil supply to the moving parts of the compressor. According to the invention, the oil suction pipe is mounted for rotation about the axis of the crankshaft. Thereby the oil supply is maintained in any position resulting from any rotation of the compressor about the horizontal axis of its crankshaft.

A travelling field reactor and a method for separating magnetizable particles from a liquid using said travelling field reactor are disclosed. The travelling field reactor may include a tubular reactor, the outer circumference of which is provided with at least one magnet for producing a travelling field and through the interior of which the liquid flows. A displacement element may be located in the interior of the tubular reactor, said element admitting a liquid into the interior of the tubular reactor, which mixes with the liquid flowing in the reactor.
摘要:
Steam is produced from a working medium of a steam generator, e.g., a waste heat steam generator, a Kalina steam generator or an ORC steam generator, using a thermal generator mounted upstream from the steam generator. To evaporate the working medium, the steam generator uses a hot heat transmitting medium that is heated in the thermal generator before being supplied to the steam generator, thereby increasing the efficiency of the steam generator. The residual or waste heat of an industrial plant or a geothermal plant using geothermal energy is used, for example, as a heat source for the thermal generator

The invention relates to a method and to a device for condensing CO2 or CO2 separation. According to the invention the thermoacoustic effect is used, with the aid of waste heat from a power station, to produce power for a compressor for compressing a working medium, in particular for compressing a CO2-containing flue gas, and/or for cooling the working medium.
摘要:
An electric machine has a base body with a stator, a rotor shaft mounted in the base body, and a heat exchanger. Cooling ducts for a liquid cooling medium are arranged in the base body. The rotor shaft is embodied as a hollow shaft through which the liquid cooling medium can flow. The heat exchanger dissipates heat contained in the liquid cooling medium to the surroundings of the electric machine. The heat exchanger, the rotor shaft and the cooling ducts are fluidically connected in series, producing a closed circuit for the liquid medium. A feed element is arranged to co-rotate with the rotor shaft. The feed element is inserted in the closed circuit for the liquid cooling medium to forcibly circulate the liquid cooling medium in the closed circuit as the rotor shaft for the liquid cooling medium rotates.
