摘要： The invention relates to an electric generator (1), in particular a power station generator, said generator having at least one inlet (2) and an outlet (3) for at least one hollow conduit (4) for receiving a coolant fluid (5). The hollow conduit (4) can be situated in or on a rotor (6) and/or a stator (7)/ stator bars (17) and/or a shaft (8) and/or a housing (9) of the electric generator (1) and said hollow conduit (4) is set up as an evaporator (10) for receiving thermal energy from the electric generator (1) by means of the coolant fluid (5). The cooling process allows the efficiency of the electric generator (1) to be increased.

摘要： An electric machine has a base body (1), a rotor shaft (6) and a heat exchanger (10). The base body (1) comprises at least one stator (2). Cooling ducts (4) for a liquid cooling medium are arranged in the base body (1). The rotor shaft (6) is mounted in the base body (1) in such a way that the rotor shaft (6) can rotate about a rotational axis (5). The rotor shaft (6) is embodied as a hollow shaft through which liquid cooling medium can flow. The heat exchanger (10) serves to output heat contained in the liquid cooling medium to the surroundings of the electric machine. The heat exchanger (10), the rotor shaft (6) and the cooling ducts (4) are fluidically connected to one another in pairs so that a closed circuit for the liquid medium is produced. A feed element (11) is arranged in a rotationally fixed fashion on the rotor shaft (6), said feed element being connected into the closed circuit for the liquid cooling medium and being used to forcibly circulate the liquid cooling medium as the rotor shaft (6) rotates about the rotational axis (5) in the closed circuit for the liquid cooling medium.

摘要： The machine system comprises a machine (2) provided with a rotor that can be rotated about an axis (A), with a superconductor winding (10) that is coupled in a heat-conducting manner to a central coolant area (31) of a fixed heat conducting body (30) protruding into a hollow (12) of the rotor by means of a winding carrier (9) and a heat contact gas (g). The coolant area (31a) forms a line system with the line parts (22) thereof, that are laterally connected thereto, and a condenser area (18) of a cold unit (13), wherein a coolant (k,k') circulates in said line system on the basis of a thermo syphon effect. In order to maintain the supply of coolant to the central coolant area (31), even when the rotor (5) encounters difficulties, the coolant area is provided with a lining (25) that is made of a porous material, preferably a sinter material, having higher thermal conductivity.

摘要： The heat pump according to the invention comprises an internal heat exchanger and a regulating device which is designed to bring the temperature of the working fluid at the outlet of the compressor to a specifiable minimum interval above the dew point at the same pressure. By means of the aforementioned additional intervention in the heat pumping process, novel coolants can be used in heat pumps, said coolants having a low dew line slope of under 1000 (kgK
2 )/kJ in the temperature-entropy diagram and being characterized by very good safety and environmental properties.-

摘要： The water jet type pump (2) is part of a system (1) for generating an ultrahigh vacuum HV. The pump comprises at least one pump chamber (11) through which an ionic fluid (F) flows at high velocity. The chamber (11) comprises a first fluid feed (3) for the fluid F, said feed ending in a nozzle with a nozzle opening (3a), and a fluid discharge (5). A second feed (4) of the pump chamber (11) is connected to a high pressure chamber (10) to be evacuated. Gas is suctioned out of the high vacuum chamber (10) through the second feed (4) by way of the flowing fluid jet, which is used to discharge the gas out of the pump chamber (11).
