摘要： An electric coolant pump for providing an automotive cooling circuit with a coolant includes an electric motor to drive the electric coolant pump, a pump housing, a separating can, a printed circuit board, and permanently height-adjusted supporting elements. The separating can includes a substantially plane separating can bottom wall which lies in a cross plane, and a substantially cylindrical separating can shell which fluidically separates a wet zone from a dry zone. The printed circuit board is arranged substantially parallel to and not in direct contact with the separating can bottom wall so that an axial gap exists which is filled with a heat conductive means. The supporting elements axially support the plane printed circuit board. Each supporting element has a distal tip which is trimmed to define a height-constant axial gap having a nominal gap height between the printed circuit board and the separating can bottom wall.

摘要： A rotary apparatus for inputting thermal energy into fluidic medium is provided, the apparatus comprises: a casing with at least one inlet and at least one outlet; a rotor comprising at least one row of rotor blades configured as impulse impeller blades arranged over a circumference of a rotor hub mounted onto a rotor shaft; at least one row of stationary nozzle guide vanes arranged upstream of the at least one row of the rotor blades, respectively; and at least one row of stationary diffuser vanes arranged downstream of the at least one row of the rotor blades, respectively. The apparatus is configured to impart an amount of thermal energy to a stream of fluidic medium directed along a flow path formed inside the casing between the inlet and the outlet by virtue of a series of energy transformations occurring when said stream of fluidic medium successively passes through the blade/vane rows formed by the nozzle guide vanes, the rotor blades and the diffuser vanes, respectively, wherein, in said apparatus, a space formed between an exit from the at least one row of diffuser vanes and an entrance to the at least one row of nozzle guide vanes in a direction of the flow path formed inside the casing between the inlet and the outlet is made variable to regulate the amount of thermal energy input to the stream of fluidic medium propagating through the apparatus. Related uses and a method for inputting thermal energy into a fluidic medium are further provided.

摘要： A water-cooling module includes a main body. The main body has a receiving space and a water room partitioning board. The receiving space is partitioned by the water room partitioning board into a pump chamber and a heat exchange chamber. The pump chamber and the heat exchange chamber communicate with each other through at least one communication section. A pump unit is disposed in the pump chamber. A heat transfer unit is disposed in the heat exchange chamber. A cooling fluid is filled up in the main body to circulate within the pump chamber and the heat exchange chamber. The pump unit is entirely immersed in the cooling fluid so that the operation efficiency of the pump unit is enhanced and the main body is thinned. Moreover, the problem of overheating of the pump unit in operation is solved.

摘要： A method of transferring a liquefied gas under pressure contained in a container into a tank or a gas transport network. The container is connected to a recirculation circuit that includes a heater and a recirculation pump connected in series with the heater, upstream from the heater, and arranged to discharge liquefied gas taken from the bottom of the container into the heater, the method including connecting the container to the tank or to the network, via a circuit for transferring the liquefied gas in the liquid phase and not having a pump; allowing the liquefied gas to be transferred to the tank or to the network via the transfer circuit under the effect of a higher pressure in the container; and operating the pump to compensate for the reduction in pressure inside the container during transfer.

摘要： A cryogenic pump for liquefied gases is provided, which shortens precooling time, has a small loss of cryogenic liquefied gas, excels in pump efficiency, and is advantageous in cost. A motor 1 and an impeller 2 are coupled by a shaft 3 for transmitting a rotative drive force therebetween, and the motor 1 is arranged on an upper side and the impeller 2 is arranged on a lower side. The motor 1 and the impeller 2 exist in an enclosed space 14 where they are communicated with each other and into which the cryogenic liquefied gas is introduced. A heat adjusting unit 11 is provided between the motor 1 and the impeller 2, the heat adjusting unit maintaining existence of the impeller 2 in a liquid phase of the cryogenic liquefied gas and maintaining existence of the motor 1 in a gas phase of the cryogenic liquefied gas. Thus the submerging of the motor 1 in the liquid becomes unnecessary, whereby the precooling time can be reduced remarkably and the loss of cryogenic liquefied gas due to vaporization caused by the submerging can be reduced, and in addition, the motor 1 itself can be configured at a comparatively low cost.
摘要翻译：提供了一种用于液化气体的低温泵，其缩短预冷时间，低温液化气体的损失小，泵效率优异，成本有利。马达1和叶轮2通过轴3联接，用于传递其间的旋转驱动力，马达1布置在上侧，叶轮2布置在下侧。电动机1和叶轮2存在于封闭空间14中，它们彼此连通并且引入低温液化气体。在电动机1和叶轮2之间设置有热调节单元11，该热调节单元保持叶轮2在低温液化气体的液相中的存在，并且将电动机1的存在保持在低温液化气相加油站。因此，电动机1在液体中的浸没变得不必要，从而可以显着降低预冷时间，并且可以减少由浸没引起的汽化引起的低温液化气体的损失，另外，马达1本身也可以被配置成本相对较低。
