Definitions
- the invention relates to a device of superconductivity technology
- metal oxide superconductor materials have been known since 1987 with transition temperatures T c of over 77 K. The latter materials are also referred to as high (high) T c superconductor materials or HTS materials.
- cryocoolers For cooling windings with HTS conductors, refrigeration units in the form of so-called cryocoolers with a closed helium compressed gas circuit are preferably used in the temperature range mentioned. Such cryocoolers are in particular of the Gifford-McMahon or Stirling type or are designed as so-called pulse tube coolers. Corresponding cooling units also have the advantage that the cooling capacity is available at the push of a button and the user is spared the handling of cryogenic liquids. When using such cooling units, e.g. a superconducting magnetic coil winding is only indirectly cooled by heat conduction to a cold head of a refrigerator and is therefore free of refrigerants (see also the text from ICEC 16).
- refrigerator cooling has already been implemented using good heat-conducting connections such as, for example, in the form of possibly also flexible copper pipes between a cold head of a corresponding cooling unit and the superconducting winding of the magnet (cf. the above-mentioned literature from ICEC 16 , especially pages 1113 to 1116).
- good heat-conducting connections such as, for example, in the form of possibly also flexible copper pipes between a cold head of a corresponding cooling unit and the superconducting winding of the magnet (cf. the above-mentioned literature from ICEC 16 , especially pages 1113 to 1116).
- the large cross sections required for good thermal coupling then lead to a considerable increase in cold mass. This is disadvantageous in particular in the case of the spatially extended magnetic systems that are customary in MRI applications, because of the longer cooling times.
- a line system can also be provided in which a He gas stream circulates (cf. e.g. US 5,485,730).
- the object of the present invention is to provide a device for superconducting technology with the features mentioned at the beginning, in which the effort for cooling a superconducting winding is reduced.
- the thermal coupling means between the at least one winding and the at least one cold head should be designed as a line system with at least one pipeline for a refrigerant circulating therein according to a thermosiphon effect.
- a cold head is understood here to mean any cold surface of a refrigeration unit via which the refrigeration output is given directly or indirectly to the refrigerant.
- Such a piping system has at least one closed pipeline that runs at a slope between the cold head and the superconducting winding.
- the gradient is at least in some parts of the pipeline generally more than 0.5 °, preferably more than 1 ° with respect to the horizontal.
- the refrigerant in this pipeline recondenses on a cold surface of the refrigeration unit or cold head and from there reaches the area of the superconducting winding, where it heats up and generally evaporates.
- the refrigerant thus evaporated then flows back into the area within the pipeline Cold surface of the cold head.
- the corresponding circulation of the refrigerant takes place on the basis of a so-called “thermosiphon effect *.
- thermosiphon (as a corresponding line system is also called) for transferring the cooling capacity to the winding
- the required circulating amount of the cryogenic refrigerant is considerably reduced compared to a bath cooling system, for example by a factor of about 100. Since also If the liquid only circulates in pipelines with comparatively small diameters, which are generally of the order of a few centimeters, the pressure build-up in a quench is technically manageable without problems.
- the reduction in the amount of liquid refrigerant in the system especially when using helium or neon as the refrigerant, is also a significant cost advantage.
- a thermosiphon also offers the advantage of good thermal coupling regardless of the spatial distance between the cold head and the object to be cooled.
- the line system can have two or more pipes which are filled with different refrigerants with different condensation temperatures. Depending on the requirements of the application, this enables working temperatures to be graded accordingly, for example for pre-cooling, a quasi-continuous thermal coupling or a quasi-continuous thermal coupling through overlapping working temperature ranges of the refrigerants.
- the subsystems can either be connected to a common cold head or be thermally coupled to separate cold heads of a refrigeration unit.
- the superconducting magnet of the device can particularly advantageously contain a winding which has superconducting HTS material and in particular can also be kept at a temperature below 77K.
- a device according to the invention of superconductivity technology must also be designed for LTS magnets.
- FIG. 1 shows the cooling of an MRI magnet with two windings
- FIG. 2 shows the cooling of another MRI magnet with four windings.
- the superconducting technology device which is generally designated 2 in FIG. 1 and is only executed in its details that are essential to the invention, can in particular be part of an MRI magnet system.
- Embodiments known per se with a so-called C magnet are assumed (see e.g. DE 198 13 211 C2 or
- This system therefore contains a non-detailed, preferably superconducting magnet 3 with an upper superconducting winding 4a lying in a horizontal plane and a lower superconducting winding 4b arranged parallel thereto.
- These windings can in particular be made with conductors made of high-T c superconductor material, such as (Bi, Pb) 2 Sr 2 Ca 2 Cu 3 O x , for reasons of a high current carrying capacity can be kept at an operating temperature below 77 K.
- the windings have a ring shape. They are each housed in a corresponding vacuum housing, not shown.
- the cooling capacity for cooling the windings 4a and 4b is provided by a cooling unit (not shown in detail) with at least one cold head 6 located at its cold end.
- This cold head has a cold surface 7 to be kept at a predetermined temperature level or is thermally connected to it.
- the interior of a condenser chamber 8 is thermally coupled to this cold surface; for example, the cold surface 7 forms a wall of this room. According to the exemplary embodiment shown, the interior of this condenser chamber 8 is divided into two compartments 9a and 9b.
- a pipeline 10a of a pipeline system 10 is connected to the (first) subspace 9a.
- This pipeline first leads from the part space 9a into the area of the superconducting winding 4a, where it is in good heat-conducting contact with the winding.
- the pipeline 10a runs in spiral windings along the inside of the winding.
- the attachment on the inside is not mandatory; it is only important that the pipeline reaches the entire circumference of the winding with a permanent slope and is thermally well coupled there to the parts to be cooled or the conductor of the winding.
- the pipeline 10a includes at least the most essential parts with the horizontal h an incline (or inclination) angle ⁇ of more than 0.5 °, preferably more than 1 °.
- the gradient angle ⁇ in the area of the winding 4a is approximately 3 °.
- a first refrigerant kl for example neon (Ne)
- Ne is located in the pipeline 10a laid with the slope.
- the refrigerant kl circulates in the pipeline 10a including the associated subspace 9a due to a thermosiphon effect known per se.
- the refrigerant condenses in the sub-space 9a on the cold surface 7 and reaches the area of the superconducting windings in liquid form.
- the refrigerant heats up, for example with at least partial evaporation, and flows back in the pipeline 10a into the subspace 9a, where it is recondensed.
- the line system 10 comprises a second pipeline 10b, which runs parallel to the first pipeline 10a and is filled with a further refrigerant k2.
- This refrigerant is different from the first refrigerant kl, ie it has a different, preferably higher, condensation temperature.
- nitrogen (N 2 ) is selected for the refrigerant k2.
- the pipeline 10b is connected to the (second) sub-space 9b of the condenser chamber 8.
- the second refrigerant k2 also circulates in the closed pipeline 10b and the sub-space 9b due to a thermosiphon effect. When the magnet windings cool down, the second refrigerant k2 is first condensed, the
- Windings can be pre-cooled to about 70 to 80 K, for example if N 2 is used as the refrigerant k2.
- the first refrigerant kl located in the pipeline 10a then condenses with the comparatively lower condensation temperature and thus leads to a further cooling to the intended operating temperature of, for example, 20 K (when using Ne as the first refrigerant kl).
- the second refrigerant k2 can be frozen out at this operating temperature in the area of the partial space 9b.
- the device 2 according to the invention for superconducting technology can of course also have only one line system with only a single pipeline.
- thermosiphon pipeline which is filled with N 2 or Ar, for example - in addition to the thermal connection to the second stage - also connect to the first (warmer) stage.
- thermosiphon cooling can also be used for magnets that have vertically arranged windings.
- An embodiment of a device according to the invention with corresponding windings is indicated in Figure 2.
- a spiral shape as in the case of the exemplary embodiment according to FIG.
- each pipeline 15i can therefore be dispensed with here and the gradient angle in large parts of the line system generally designated by 20 is approximately 90 °.
- a condenser chamber 18 and a cold head are generally placed above the windings to provide the required slope.
- At least one pipeline 15i is required per winding since, in contrast to horizontally arranged windings, not one pipeline can reach all windings while maintaining the gradient.
- the entire pipeline system 20 formed from the pipelines 15i must either be designed as a system of communicating tubes and be completely flooded with the liquid refrigerant in the area of the windings 14. This is indicated in FIG. 2 by a darker coloring of the refrigerant kl, while the evaporated refrigerant is colored lighter and labeled kl ⁇ .
- each pipeline 15i must have a separate condenser (partial) chamber on the cold head.
- a line system with parallel pipes filled with different refrigerants (kl or k2) can also be provided.
- a device according to the invention for superconducting technology can have a line system with at least one pipeline, in which there is also a mixture of two refrigerants with different condensation temperatures. Then, with a gradual cooling, the gas with the highest condensation temperature can initially condense and form a closed circuit for heat transfer to a winding to be cooled. After this winding has been pre-cooled to the triple point temperature of this gas, it will then freeze out in the region of the condenser chamber, whereupon the other gas mixture component with the lower condensation temperature ensures further cooling to the operating temperature.
- the gases He, H 2 , Ne, 0 2 , N 2 , Ar and various hydrocarbons are suitable as refrigerants.
- the cold gas is selected in such a way that operating temperature, the refrigerant is both gaseous and liquid. This ensures circulation using a thermosiphon effect.
- Warm and / or cold expansion tanks can be provided on the line system for targeted adjustment of the filling quantity while simultaneously limiting the system pressure.
- refrigerant also depends on the superconductor material used. If an LTS material such as Nb 3 Sn is provided, only He can be used as a refrigerant.
