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.
- 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 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
- 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.
