As shown in fig. 1-5, an embodiment of the present invention provides a cooling system for levitation propulsion of an integrated coil, wherein the system comprises a track beam 1, an integrated coil module 2, a master input pipeline 4, a master output pipeline 5, a slave input pipeline 6, a slave output pipeline 7, a return pipe 13, a return pipe input end 15 and a return pipe output end 16, wherein the integrated coil module 2 is arranged on the inner wall of the track beam 1 and interacts with a superconducting magnet arranged on a maglev train to generate a force for controlling the operation of the maglev train, wherein the master input pipeline 4 and the master output pipeline 5 are arranged in the track beam 1, wherein the return pipe 13 is arranged in the integrated coil module 2, wherein the master input pipeline 4 is communicated with the return pipe input end 15 through the slave input pipeline 6, wherein the master output pipeline 5 is communicated with the return pipe output end 16 through the slave output pipeline 7, wherein a cooling medium enters the return pipe 13 from the return pipe input end 15 through the master input pipeline 4 and the slave input pipeline 6, and is integrally cooled by the return pipe output pipeline 16 from the output pipeline 7 to the integrated coil module 2.
The track beam 1 is a bearing component, and the whole track beam can be in an inverted T shape, for example, and can be built by reinforced concrete. When the integrated coil modules are multiple, the main input pipeline inputs cooling medium to the return pipes in the corresponding single integrated coil module through different auxiliary input pipelines, and the cooling medium circulated by the return pipes in the single integrated coil module is output to the main output pipeline through the corresponding auxiliary output pipeline (namely, the return pipes in each integrated coil module correspond to a group of auxiliary input pipelines and auxiliary output pipelines).
Through the technical scheme, the propulsion coil and the suspension guide coil can be integrated, so that the stability and the safety of the coil are greatly improved, and the installation is facilitated; meanwhile, the main input pipeline, the main output pipeline, the auxiliary input pipeline, the auxiliary output pipeline and the return pipe arranged in the integrated coil module form a cooling circulation loop, so that the propulsion coil and the suspension guide coil in the module can dissipate heat better. In addition, as the coils are integrated in a module mode, a heat dissipation device is not required to be arranged for each coil, and the manufacturing process and cost of the coil module are reduced. Furthermore, by arranging the main output line within the rail beam, heat dissipation in the vacuum lines can be avoided while saving space.
According to one embodiment of the invention, the system further comprises a linear connector 10 and a three-phase connector 11, wherein the main input pipeline 4 is communicated with the auxiliary input pipeline 6 through the three-phase connector 11, the auxiliary input pipeline 6 is communicated with the return pipe input end 15 through the linear connector 10, the main output pipeline 5 is communicated with the auxiliary output pipeline 7 through the three-phase connector 11, and the auxiliary output pipeline 7 is communicated with the return pipe output end 16 through the linear connector 10.
That is, the main input pipeline can be separated into multiple paths through the three-phase connector, and then the main input pipeline can be communicated with the input end of the return pipe through the linear connector; similarly, the main output pipeline can be separated into multiple paths through the three-phase connector, and then the main output pipeline can be communicated with the output end of the return pipe through the linear connector. Therefore, the cooling medium can be input into the return pipes in the integrated coil modules through the main input pipeline, and is output to all circulating cooling medium circulated through the return pipes through the main output pipeline (namely, all circulating cooling medium circulated through the return pipes) through the return pipes in the integrated coil modules, so that most of heat generated by coils in the whole integrated coil modules is taken away, and the cooling of the integrated coil modules is realized.
The three-phase connector 11 may be a T-shaped connector.
According to one embodiment of the present invention, a plurality of bolts 17 are disposed on the inner wall of the track beam 1 (see fig. 4), a plurality of through holes adapted to the plurality of bolts 17 are disposed on the integrated coil module 2, and the plurality of bolts 17 pass through the corresponding through holes and then fix the integrated coil module 2 on the inner wall of the track beam 1 through corresponding nuts 3 (see fig. 1).
Therefore, the fastening of the integrated coil module can be realized through the matching of the bolts and the nuts.
It will be appreciated by those skilled in the art that the above-described manner of securing the bolt and nut is merely exemplary and is not intended to limit the present invention.
Referring to fig. 6B-6D, the number of through holes (bolt holes) may be 7, but this is merely exemplary and not intended to limit the present invention.
According to one embodiment of the present invention, the integrated coil module 2 includes a propulsion coil 12 and a levitation guide coil 14, the loop-shaped tube 13 is disposed between the propulsion coil 12 and the levitation guide coil 14, the propulsion coils 12 are connected in series through a connecting wire 9, and the levitation guide coils 14 corresponding to the track beams 1 on two sides are connected through hinges 8.
That is, the rail beams 1 are arranged symmetrically, for example on both sides of the rail, and the corresponding levitation guide coils 14 on the rail beams arranged symmetrically on both sides are connected by the hinges 8.
Thus, stable levitation guidance of the magnetic levitation train can be achieved through the hinge.
As shown in fig. 6A to 6D, the inside of the integrated coil module may be divided into three layers, fig. 6A shows the levitation guide coil at the first layer, fig. 6B shows the propulsion coil at the third layer, fig. 6C shows the return pipe at the second layer, and when the input end of the return pipe flows into the cooling medium, the cooling medium flows in the direction of an arrow and finally flows out from the output end of the return pipe, thereby taking away heat generated by the levitation guide coil and the propulsion coil.
Wherein the propulsion coil 12 is used for interacting with a superconducting magnet arranged on the magnetic levitation train to generate propulsion force for controlling the magnetic levitation train to advance, and the levitation guiding coil 14 is used for interacting with the superconducting magnet arranged on the magnetic levitation train to generate levitation force and guiding force for controlling levitation and direction of the magnetic levitation train. Specifically, when the propulsion coil is energized with current, the propulsion coil and the superconducting magnet interact to provide propulsion for the train; meanwhile, the superconducting magnet can induce current in the levitation guide coil, and the levitation guide coil has an induced magnetic field due to the existence of the induced current, so that the induced magnetic field and the superconducting magnet interact to provide levitation force and guide force for the train.
In the invention, the return pipe can adopt a form of repeated circulation, and the degree of the density of the return pipe can be set according to the specific positions of the propulsion coil and the suspension guide coil in the module, the positions of the bolt holes (preventing the return pipe from interfering with the bolt holes), the size of the coil, the heating power of the coil, the allowable temperature limit of the coil and other factors, and the invention is not limited to the degree.

According to one embodiment of the present invention, the molding material of the integrated coil module 2 further includes a reinforcing material.
When the epoxy resin is used as a pouring molding material of the integrated coil module, the heat dissipation performance of the system can be improved by arranging the heat conducting material layer; meanwhile, the mechanical property of the material can be enhanced by adding the reinforcing material into the module.
According to one embodiment of the present invention, the integrated coil module 2 is formed by a reaction injection molding method.
Those skilled in the art will appreciate that the foregoing description of materials and processes is by way of example only and is not intended to limit the invention.
According to the embodiment of the invention, the connecting part of the linear connector and the three-phase connector can be subjected to sealing treatment, so that the circulating pipeline has higher reliability, and long-term working is ensured not to leak.
Further, the cooling medium may be subjected to a purge treatment prior to introduction to prevent fouling and oxides from clogging the circulation line. In addition, the introduced cooling medium can have a predetermined pressure to ensure rapid circulation in the integrated coil module, and the specific pressure can be determined according to practical conditions, which is not limited by the present invention.

Spatially relative terms, such as "above … …," "above … …," "upper surface at … …," "above," and the like, may be used herein for ease of description to describe one device or feature's spatial location relative to another device or feature as illustrated in the figures. It will be understood that the spatially relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures.

The device may also be positioned in other different ways (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
In addition, the terms "first", "second", etc. are used to define the components, and are only for convenience of distinguishing the corresponding components, and the terms have no special meaning unless otherwise stated, and therefore should not be construed as limiting the scope of the present invention.
