Description

Technical Field

[0001] This application relates to the field of maglev train technology, and more specifically, to a maglev train and its heat-dissipating magnetic poles, electromagnets, system, and control method. Background Technology

[0002] High-speed maglev trains are typically equipped with magnetic poles, and the heat dissipation problem during the operation of these poles is a key indicator limiting their performance. This is because a continuous direct current is supplied to the pole windings to achieve levitation, and this continuous current flow causes heat to accumulate and the temperature to rise. However, due to limitations in the heat dissipation structure of the pole windings and the temperature tolerance limits of the insulation materials, the operating temperature of the magnetic poles cannot be too high. Adjustments and controls are necessary to prevent high temperatures from damaging the pole insulation system and reducing the pole's lifespan. Currently, wind cooling is the primary method for heat dissipation, making real-time and effective temperature control of the magnetic poles impossible.

[0003] In summary, how to provide a heat dissipation system that can control the heat dissipation effect of magnetic poles in real time is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0055] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] The core of this application is to provide a maglev train and its heat dissipation magnetic poles, electromagnets, system, and control method, which can control the heat dissipation effect of the magnetic poles in real time.

[0057] This application provides a magnetic pole heat dissipation system that can be applied to a magnetic pole 4 with a heat dissipation channel 41 to improve its heat dissipation effect. The magnetic pole heat dissipation system includes an oil-cooled heat dissipation component 1. The heat dissipation channel 41 has an inlet 42 and an outlet 43. The oil-cooled heat dissipation component 1 and a controller 3 are also included. The oil-cooled heat dissipation component 1 includes a circulating pump 10, an active radiator 11, and an oil tank 12. The inlet of the circulating pump 10 is connected to the inner cavity of the oil tank 12, and the outlet of the circulating pump 10 is connected to the inlet 42. The inlet of the active radiator 11 is connected to the outlet 43, and the outlet of the active radiator 11 is connected to the inner cavity of the oil tank 12. The controller 3 is signal-connected to the oil-cooled heat dissipation component 1 and is used to control the working state of the oil-cooled heat dissipation component 1.

[0058] refer to Figure 2 , Figure 5 , Figure 8 , Figure 11 As explained, the components in the oil-cooled heat dissipation assembly 1 and the magnetic pole 4 are connected in the manner of oil tank 12-circulation pump 10-magnetic pole 4-active radiator 11-oil tank 12 to form a circulation loop. In use, the circulation pump 10 and the active radiator 11 are started. The circulation pump 10 provides power so that the cooling oil in the oil tank 12 is drawn out and flows back to the oil tank 12 along the circulation loop. After the cooling oil flows through the magnetic pole 4, it will carry away the heat generated by the magnetic pole 4. The cooling oil flowing through the magnetic pole 4 flows into the active radiator 11 for heat dissipation and cooling, and then flows back to the oil tank 12 to prepare for cooling the magnetic pole 4 when it flows along the circulation loop again.

[0059] Correspondingly, the controller 3 is connected to the oil-cooled heat dissipation assembly 1, thereby controlling the operating state of the oil-cooled heat dissipation assembly 1. The operating state is illustrated in the following embodiment:

[0060] In some embodiments, the operating state includes an oil-free operating state, and in the oil-free operating state, the oil pipes connected to the heat dissipation channel 41 of the magnetic pole 4 remain blocked.

[0061] In some embodiments, the operating state includes an oil-cooled operating state, i.e., cooling oil can flow into the magnetic pole 4, reference. Figure 1 , Figure 2 and Figure 3At this time, cooling of the magnetic pole 4 can be achieved. Optionally, the working state or oil-cooled working state includes a high-efficiency oil-cooled working state. In the high-efficiency oil-cooled working state, multiple heat dissipation channels 41 of the magnetic pole 4 can be used to enter and exit cooling oil. That is, oil pipes are connected to the inlet 42 and outlet 43 of several heat dissipation channels 41 of the magnetic pole 4, and the oil pipes connected to at least two heat dissipation channels 41 of the magnetic pole 4 are kept unobstructed. Optionally, the working state or oil-cooled working state includes an inefficient oil-cooled working state. In the inefficient oil-cooled working state, a single heat dissipation channel 41 of the magnetic pole 4 can be used to enter and exit cooling oil. That is, oil pipes are connected to both the inlet 42 and outlet 43 of one heat dissipation channel 41 of the magnetic pole 4, and the oil pipe connected to one heat dissipation channel 41 of the magnetic pole 4 is kept unobstructed. That is, the controller can adjust the on / off state of the several heat dissipation channels 41 of the magnetic pole 4.

[0062] Based on the air-cooled heat dissipation structure of the rail vehicle, an additional oil-cooled heat dissipation component 1 is configured, which can greatly improve the heat dissipation efficiency of the magnetic pole 4. In addition, the oil-cooled heat dissipation component 1, together with the controller 3, can control the oil cooling efficiency level, so as to control the heat dissipation effect of the magnetic pole 4 in real time and ensure the normal operation of the magnetic pole 4.

[0063] It should be noted that, in some embodiments, the magnetic pole heat dissipation system includes a magnetic pole 4.

[0064] Based on the above embodiments, the magnetic pole 4 also has an emergency injection port 44, which is connected to the heat dissipation channel 41; the oil-cooled heat dissipation assembly 1 also includes a heat dissipation pipe assembly 13, an injection control switch valve 14, an discharge control switch valve 15, an emergency heat dissipation pipe assembly 16, and an emergency control switch valve 17; the heat dissipation pipe assembly 13 connects several magnetic poles 4 in series through the injection port 42 and the discharge port 43; the emergency heat dissipation pipe assembly 16 is connected to several magnetic poles 4 through the emergency injection port 44; and the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16 are independent of each other; the first end inlet of the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16 is connected to the outlet of the circulating pump 10, and the second end outlet is connected to the inlet of the active radiator 11; a corresponding injection control switch valve 14 is provided at the injection port 42 of several magnetic poles 4 to control the opening and closing of the corresponding injection port 42; a corresponding discharge control switch valve 15 is provided at the discharge port 43 of several magnetic poles 4 to control the opening and closing of the corresponding discharge port 43.

[0065] refer to Figures 1 to 12 As explained, rail vehicles are typically equipped with several magnetic poles 4. The magnetic pole cooling system connects each magnetic pole 4 in series through a circulation loop formed by the cooling pipe assembly 13, so that the cooling oil can flow through each magnetic pole 4 in sequence to achieve cooling of the magnetic pole 4.

[0066] To prevent the failure of one or more magnetic poles 4 from affecting the normal operation of other magnetic poles 4, each magnetic pole 4 is equipped with an emergency injection port 44. This emergency injection port 44 is connected to a heat dissipation channel 41. Cooling oil flowing into the magnetic pole 4 through the emergency injection port 44 can then flow out through the injection port 42 and / or outlet port 43 of the heat dissipation channel 41. Correspondingly, the oil cooling heat dissipation assembly 1 is equipped with a heat dissipation pipe assembly 13 and an emergency heat dissipation pipe assembly 16. The heat dissipation pipe assembly 13 connects several magnetic poles 4 in series via the injection port 42 and outlet port 43 of the magnetic poles 4, forming a cooling channel. The emergency heat dissipation pipe assembly 16 connects several magnetic poles 4... The emergency injection port 44 can serve as an emergency or replenishment port to replenish cooling oil into the heat dissipation channel 41 of the magnetic pole 4. The first end opening of the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16 is connected to the outlet of the circulation pump 10, and the second end opening is connected to the inlet of the active radiator 11. The circulation pump 10 can pump cooling oil into the aforementioned cooling channel and into it through the emergency injection ports 44 of the magnetic poles 4 themselves. The cooling oil flows through the magnetic poles 4 to dissipate heat. Furthermore, the oil cooling heat dissipation assembly 1 is also equipped with several injection sub-control switch valves 14, several discharge sub-control switch valves 15, and several emergency sub-control switch valves 17.

[0067] Each magnetic pole 4 is equipped with its own injection control valve 14, discharge control valve 15 and emergency control valve 17 to control the opening and closing of its own injection port 42, discharge port 43 and emergency injection port 44.

[0068] In some embodiments, the oil cooling working state includes the normal working state, and in the normal working state, all magnetic poles 4 are not faulty. In the circulation loop, the injection sub-control switch valve 14 and the discharge sub-control switch valve 15 corresponding to all magnetic poles 4 are in the open state, while the emergency sub-control switch valve 17 corresponding to all magnetic poles 4 are in the closed state.

[0069] In some embodiments, the oil-cooled working state includes an emergency working state. In the emergency working state, the injection control valve 14, the discharge control valve 15, and the emergency control valve 17 corresponding to the faulty magnetic pole 4 are all kept closed. In the circulation loop, the discharge control valve 15, which is connected to the injection port 42 of the faulty magnetic pole 4, is closed, the injection control valve 14, which is connected to the injection port 42 of the magnetic pole 4, is closed, and the emergency control valve 17, which is connected to the adjacent magnetic pole 4 of the faulty magnetic pole 4, is open. This allows for rapid adjustment when a local magnetic pole 4 of the electromagnet fails, ensuring the electromagnet can continue to operate and the high-speed maglev train can run normally.

[0070] Regarding emergency operating conditions, in some embodiments, the series sequence or sequential order of several magnetic poles 4 along the allowable cooling oil flow direction is magnetic pole N1, magnetic pole N2… magnetic pole Ni… magnetic pole Nm, and the several injection sub-control switch valves 14 corresponding to magnetic poles N1, N2… Ni… Nm are injection sub-control switch valves AX1, injection sub-control switch valve AX2… injection sub-control switch valve AXi… injection sub-control switch valve AXm; the several discharge sub-control switch valves 15 corresponding to magnetic poles N1, N2… Ni… Nm are discharge sub-control switch valves BX1, discharge sub-control switch valve BX2… discharge sub-control switch valve BXi… discharge sub-control switch valve BXm; the several emergency sub-control switch valves 17 corresponding to magnetic poles N1, N2… Ni… Nm are emergency sub-control switch valves C1, emergency sub-control switch valve C2… emergency sub-control valve Ci… emergency sub-control valve Cm, as illustrated in the following embodiments:

[0071] In some embodiments, the emergency operating state includes a first emergency operating state, in which magnetic pole N1 malfunctions, such as... Figure 4 , Figure 5 and Figure 6 As shown, the injection control valve AX1, discharge control valve BX1, and emergency control valve C1 configured for magnetic pole N1 are all in the closed state, while the injection control valve AX2 configured for magnetic pole N2 is in the closed state, and the discharge control valve BX1 and emergency control valve C1 are all in the open state. At this time, the cooling oil cannot flow into magnetic pole N1 through the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16, but can flow into magnetic pole N2 through the emergency heat dissipation pipe assembly 16, and then flow through magnetic pole N3... magnetic pole Nm through the pipe located after magnetic pole N2 in the cooling channel formed by the heat dissipation pipe assembly 13.

[0072] In some embodiments, the emergency operating state includes a last-position emergency operating state, in which the magnetic pole Nm fails, such as... Figure 10 , Figure 11 and Figure 12 As shown, the injection control valve AXm, discharge control valve BXm, and emergency control valve Cm configured for magnetic pole Nm are all in the closed state, while the discharge control valve BXm-1 configured for magnetic pole Nm-1 is in the closed state, and the injection control valve AXm-1 and emergency control valve Cm-1 are in the open state. At this time, the cooling oil cannot flow into magnetic pole Nm through the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16, while the cooling oil flowing through magnetic pole Nm-1 can flow out through the emergency heat dissipation pipe assembly 16 and flow to the active radiator 11.

[0073] In some embodiments, the emergency operating state includes an intermediate emergency operating state. In the intermediate emergency operating state, the magnetic pole Ni malfunctions, and the magnetic pole Ni is any one of magnetic poles N2 to Nm-1. The injection sub-control switch valve AXi, discharge sub-control switch valve BXi, and emergency sub-control switch valve Ci configured for magnetic pole Ni are all closed. Meanwhile, the discharge sub-control switch valve BXi-1 configured for magnetic pole Ni-1 is closed, and the injection sub-control switch valve AXi-1 and emergency sub-control switch valve Ci-1 are both open. The injection sub-control switch valve Ni+1 configured for... When the sub-control valve AXi+1 is closed, and the discharge sub-control valve BXi+1 and the emergency sub-control valve Ci+1 are both open, the cooling oil cannot flow into the magnetic pole Ni through the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16. Instead, the cooling oil flowing through the magnetic pole Ni-1 can flow out through the emergency heat dissipation pipe assembly 16 and into the magnetic pole Ni+1. After flowing into the magnetic pole Ni+1, the oil will flow through the pipe located after the magnetic pole Ni+1 in the cooling channel formed by the heat dissipation pipe assembly 13, and then through the magnetic poles Ni+2...Nm.

[0074] For example, when magnetic pole N2 malfunctions, such as Figure 7 , Figure 8 and Figure 9 As shown, the injection control valve AX2, discharge control valve BX2, and emergency control valve C2 configured for magnetic pole N2 are all in the closed state, while the discharge control valve BX1 configured for magnetic pole N1 is in the closed state, and the injection control valve AX1 and emergency control valve C1 are all in the open state. The injection control valve AX3 configured for magnetic pole N3 is in the closed state, and the discharge control valve BX3 and emergency control valve C3 are all in the open state. At this time, the cooling oil cannot flow into magnetic pole N2 through the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16. However, the cooling oil flowing through magnetic pole N1 can flow out through the emergency heat dissipation pipe assembly 16 and flow into magnetic pole N3. After flowing into magnetic pole N3, it will flow through the pipes located after magnetic pole Ni+1 in the cooling channels formed by the heat dissipation pipe assembly 13, and then through magnetic pole N4... magnetic pole Nm.

[0075] Based on the above embodiments, the magnetic pole heat dissipation system further includes a temperature acquisition sensor 2, which is used to acquire the operating temperature of the magnetic pole 4; the controller 3 is connected to the oil cooling heat dissipation component 1 and the temperature acquisition sensor 2, and is used to control the operation of the oil cooling heat dissipation component 1 according to the received operating temperature of the magnetic pole 4, and when the operating temperature is higher than a first threshold.

[0076] refer to Figure 2 , Figure 5 , Figure 8 , Figure 11To ensure the control performance of the magnetic pole heat dissipation system, a temperature acquisition sensor 2 is also provided. The temperature acquisition sensor 2 can be a temperature sensor installed on the magnetic pole 4, a non-contact infrared thermometer, or a controller that can detect and obtain the temperature of the magnetic pole 4. Correspondingly, the controller 3 is connected to the temperature acquisition sensor 2 to obtain the working temperature of the magnetic pole 4 in real time. Then, the controller 3 can adjust the oil cooling heat dissipation component 1 to a suitable working state according to the actual situation of the magnetic pole 4 during operation, so that the temperature of the magnetic pole 4 can be stably maintained at the target temperature, which can be a threshold or range.

[0077] Furthermore, the controller is also used to control the output flow of the circulating pump 10 according to the working temperature of the magnetic pole 4, so that the working temperature of the magnetic pole 4 is stable, for example, kept within the target temperature range. Especially in emergency working conditions, the internal cooling oil circulation speed of the magnetic pole heat dissipation system adopts a closed-loop real-time adjustment mode with the working temperature of the magnetic pole 4, which is beneficial to reduce oil cooling energy consumption.

[0078] Based on the above embodiment, the magnetic pole 4 has two heat dissipation channels 41 and two sets of heat dissipation pipe assemblies 13. One set of heat dissipation pipe assemblies 13 is connected to one heat dissipation channel 41 of the magnetic pole 4, and the other set of heat dissipation pipe assemblies 13 is connected to the other heat dissipation channel 41 of the magnetic pole 4.

[0079] refer to Figure 2 , Figure 5 , Figure 8 , Figure 11 As can be seen, in this embodiment, the magnetic pole 4 is provided with two heat dissipation channels 41. The two inlet ports 42 of the magnetic pole 4 are connected to the outlet of the circulating pump 10, and the two outlet ports 43 are connected to the inlet of the active radiator 11, so that the cooling oil can flow through the magnetic pole 4 at a large flow rate and through the two heat dissipation channels 41 arranged in the magnetic pole 4, which greatly improves the heat dissipation efficiency of the magnetic pole 4.

[0080] To facilitate the differentiation of the injection control valve 14, discharge control valve 15, and emergency control valve 17 respectively installed at the injection port 42, discharge port 43, and emergency injection port 44 of magnetic pole 4, the injection control valve 14, discharge control valve 15, and emergency control valve 17 corresponding to the injection port 42, discharge port 43, and emergency injection port 44 of several heat dissipation channels 41 are defined as injection control valve AX, discharge control valve BX, and emergency control valve C, respectively, and X can be... In order to achieve high-efficiency heat dissipation, the magnetic pole 4 has several inlet ports 42 connected to the outlet of the circulating pump 10 through their respective connected sets of heat dissipation pipe assemblies 13, and the magnetic pole 4 has several outlet ports 43 connected to the inlet of the active radiator 11 through their respective connected sets of heat dissipation pipe assemblies 13, so that the cooling oil can flow through the magnetic pole 4 at a large flow rate and through the two heat dissipation channels 41 arranged on the magnetic pole 4, and emergency heat dissipation can be achieved through the emergency heat dissipation pipe assembly 16.

[0081] In some embodiments, such as Figures 1 to 15 When the magnetic pole 4 shown has two heat dissipation channels 41, one of the heat dissipation channels 41 has an injection control valve 14 and an outlet control valve 15, which are respectively injection control valve A1 and outlet control valve B1. The other has an injection port 42 and an outlet 43, which are respectively injection control valve A2 and outlet control valve B2. Correspondingly, there are two sets of heat dissipation pipe assemblies 13. One set of heat dissipation pipe assemblies 13 is connected to the injection port 42 and outlet 43 of one heat dissipation channel 41 of the magnetic pole 4, and the other set of heat dissipation pipe assemblies 13 is connected to the injection port 42 and outlet 43 of the other heat dissipation channel 41 of the magnetic pole 4.

[0082] In the embodiment where the magnetic pole 4 has two heat dissipation channels 41, during emergency operation, the injection control valve A1, injection control valve A2, discharge control valve B1, discharge control valve B2, and emergency control valve C corresponding to the faulty magnetic pole 4 are all kept closed. In the circulation loop, the discharge control valves B1 and B2, which are connected to the two injection ports 42 of the faulty magnetic pole 4, are both closed. The injection control valves A1 and A2, which are connected to the two injection ports 42 of the magnetic pole 4, are both closed. The emergency control valve C corresponding to the adjacent magnetic pole 4 is open.

[0083] To clarify, in the above-mentioned injection control valve AXi, A represents the valve as injection control valve 14, and X represents the valve being located at the injection port 42 at the first end of the corresponding heat dissipation channel 41. When several heat dissipation channels 41 of a magnetic pole 4 are defined as heat dissipation channel E1, heat dissipation channel E2... heat dissipation channel Ej... heat dissipation channel En, X equals j of heat dissipation channel Ej. For example, injection control valve A1i is located at the injection port 42 at the first end of heat dissipation channel E1, and i represents the injection control valve 14 being located at the injection port 42 of magnetic pole Ni. Similarly, in the above-mentioned discharge control valve BXi, B represents the valve as discharge control valve 15, and X represents the valve being located at the discharge port 43 at the second end of the corresponding heat dissipation channel 41, and i represents the discharge control valve 15 being located at the discharge port 43 of magnetic pole Ni. Furthermore, the aforementioned injection sub-control switch valve A1, injection sub-control switch valve A2, discharge sub-control switch valve B1, and discharge sub-control switch valve B2 are the injection sub-control switch valve AXi and discharge sub-control switch valve BXi respectively, with the code corresponding to the magnetic pole code Ei removed.

[0084] Similarly, in the aforementioned emergency control switch valve Ci, C is the symbol representing that the valve is emergency control switch valve 17, and i represents that the emergency control switch valve 17 is located at the emergency injection port 44 of the magnetic pole Ni. Furthermore, the aforementioned emergency control switch valve C is the aforementioned emergency control switch valve Ci without the symbol i corresponding to the magnetic pole symbol Ei.

[0085] It should also be noted that the type of emergency heat dissipation pipe assembly 16 is not limited, as long as the above connection requirements are met. For example, in some embodiments, the emergency heat dissipation pipe assembly 16 includes several emergency pipes, each of which has a first opening, a second opening, and a third opening. The first opening of each of the several emergency pipes is connected to the outlet of the circulating pump 10, the second opening of each of the several emergency pipes is connected to the corresponding magnetic pole 4, and the third opening of each of the several emergency pipes is connected to the inlet of the active radiator 11. That is, several emergency pipes are arranged in parallel.

[0086] Based on the above embodiments, the emergency heat dissipation pipe assembly 16 includes an emergency main pipe and several emergency branch pipes. The first end of the emergency main pipe is connected to the outlet of the circulating pump 10, and the second end of the emergency main pipe is connected to the inlet of the active radiator 11. Several emergency branch pipes are arranged in parallel, and several emergency injection ports 44 of the magnetic poles 4 are connected to the emergency main pipe through corresponding emergency branch channels. The oil-cooled heat dissipation assembly 1 also includes an emergency main switch valve 18. Several emergency sub-control switch valves 17 are provided in the corresponding emergency branch channels. The emergency main switch valve 18 is provided in the emergency main pipe and is used to control the on / off connection between the emergency injection ports 44 of the magnetic poles 4 and the outlet of the circulating pump 10.

[0087] refer to Figure 2 , Figure 5 , Figure 8 , Figure 11 As explained, the code D refers to the emergency main switch valve 18. The emergency heat dissipation pipe assembly 16 is a part of the pipe used to connect several magnetic poles 4. It consists of an emergency main pipe and several emergency branch pipes. One end of each of the several emergency branch pipes is connected to the middle of the length of the emergency main pipe, and the other end is connected to the emergency injection port 44 of the corresponding magnetic pole 4. One end of the emergency main pipe is connected to the outlet of the circulation pump 10, and the other end is connected to the inlet of the active radiator 11. The cooling oil drawn into the emergency main pipe by the circulation pump 10 will be selected to flow into the emergency main pipe depending on whether the emergency main switch valve 18 is opened or closed. The cooling oil flowing into the emergency main pipe will be selected to flow into the corresponding magnetic pole 4 depending on whether the emergency sub-control switch valve 17 is opened or closed. This setting facilitates the layout of the magnetic pole heat dissipation system.

[0088] Based on the above embodiments, the oil-cooled heat dissipation assembly 1 also includes a passive air-cooled radiator 20. The passive air-cooled radiator 20 has a heat conduction channel inside. The heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16 are both connected to the active radiator 11 through the heat conduction channel of the passive air-cooled radiator 20, and are used to receive the cooling oil flowing through the several magnetic poles 4 and dissipate heat from it.

[0089] refer to Figure 2 , Figure 5 , Figure 8 , Figure 11 As explained, in the passive air-cooled radiator 20, the air-cooling body is used to support and install the heat sink and the pipe structure of the specific heat conduction channel, etc. One end of the heat conduction channel is connected to the second end opening of the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16, while the other end of the heat conduction channel is connected to the inlet of the active radiator 11. Thus, the second end opening of the heat dissipation pipe assembly 13 and the emergency heat dissipation pipe assembly 16 is connected to the inlet of the active radiator 11 through the passive air-cooled radiator 20, so that the cooling oil flowing through several magnetic poles 4 can first flow into the passive air-cooled radiator 20 to achieve initial heat dissipation, and then flow into the active radiator 11 to achieve secondary heat dissipation.

[0090] In some embodiments, the controller 3 is used to control the passive air-cooled radiator 20 to start synchronously when the magnetic pole 4 starts working, so as to achieve cooling of the magnetic pole 4. After the passive air-cooled radiator 20 fails to meet the heat dissipation requirements of the magnetic pole 4, such as when the working temperature of the magnetic pole 4 is greater than or equal to a threshold, the controller 3 controls the oil-cooled heat dissipation component 1 to start.

[0091] Based on the above embodiments, the oil-cooled heat dissipation assembly 1 further includes a filter 19, which is disposed between the magnetic pole 4 and the circulation pump 10.

[0092] refer to Figure 2 , Figure 5 , Figure 8 , Figure 11 As can be seen, the oil-cooled heat dissipation assembly 1 is also equipped with a filter 19, and the filter 19 is placed in the front, so that the cooling oil can be filtered between flowing into the magnetic pole 4, thereby ensuring the smooth operation and stability of the magnetic pole heat dissipation system, while helping to reduce the failure rate of the magnetic pole 4.

[0093] In addition to the magnetic pole heat dissipation system described above, this application also provides a heat dissipation magnetic pole that is used in conjunction with or included in the magnetic pole heat dissipation system disclosed in the above embodiments. The heat dissipation magnetic pole has a heat dissipation channel 41 reserved inside, and the inlet 42 and outlet 43 of the heat dissipation channel 41 are both located on the outer side of the heat dissipation magnetic pole.

[0094] Based on the above embodiment, the heat dissipation channel 41 is a spiral channel to guide the flow of cooling oil and improve the heat dissipation effect.

[0095] In some embodiments, reference Figure 13 , Figure 14 and Figure 15 As explained, the magnetic pole 4 includes a main structure and an outer cover. The outer periphery of the main structure has a spiral plate structure that rotates around its own length. The outer cover is fitted on the outside of the main structure and fits against the outer periphery of the spiral plate structure to form a spiral channel. An inlet 42 and an outlet 43 are provided on the outer cover.

[0096] Of course, the structure of the heat dissipation magnetic pole is not limited to the types of the examples and embodiments above, as long as the above functions can be achieved.

[0097] Based on the above embodiments, the magnetic pole 4 is equipped with a temperature acquisition sensor 2, and the temperature acquisition sensor 2 is a temperature sensor and is built into the magnetic pole 4, which can directly and in real time detect the working temperature of the magnetic pole 4.

[0098] Based on the above embodiment, the injection port 42 and the emergency injection port 44 are located on the first side of the first end of the heat dissipation magnetic pole, and the discharge port 43 is located on the second side of the second end of the heat dissipation magnetic pole, as shown in the figure. Figure 13 and Figure 14 As shown, the injection port 42, emergency injection port 44, and discharge port 43 are located diagonally opposite the heat dissipation magnetic pole. This arrangement ensures that the heat dissipation channel 41 is filled with cooling oil and guides the cooling oil to flow in a spiral upward pattern. The cooling oil can flow out quickly and evenly in the heat dissipation magnetic pole, rapidly carrying away the heat inside the heat dissipation magnetic pole and achieving temperature exchange.

[0099] In some embodiments, reference Figure 13 , Figure 14As explained, the heat dissipation magnetic pole includes a rectangular magnetic pole body, which is the aforementioned magnetic pole 4. Two outlets 43 are provided at the upper left corner of the magnetic pole body, and the two outlets 43 are arranged along the width direction of the magnetic pole body. An emergency injection port 44 and two injection ports 42 are provided at the lower right corner of the magnetic pole body, and the emergency injection port 44 and the two injection ports 42 are arranged in any order along the width direction of the magnetic pole body.

[0100] Based on the above embodiment, the heat dissipation magnetic pole is provided with an injection control valve 14 and an discharge control valve 15 inside, with the injection control valve 14 located at the injection port 42 of the heat dissipation magnetic pole and the discharge control valve 15 located at the discharge port 43 of the heat dissipation magnetic pole.

[0101] refer to Figure 3 , Figure 6 , Figure 9 , Figure 12 As can be seen, the injection control valve 14 and the discharge control valve 15 are both integrated on the heat dissipation magnetic pole to facilitate the arrangement of the aforementioned magnetic pole heat dissipation system.

[0102] In addition to the aforementioned magnetic pole heat dissipation system and heat dissipation magnetic pole, this application also provides a high heat dissipation electromagnet including the aforementioned heat dissipation magnetic pole, and a maglev train including the aforementioned high heat dissipation electromagnet. For the structure of the high heat dissipation electromagnet and other parts of the maglev train, please refer to the prior art, which will not be repeated here.

[0103] In addition to the aforementioned magnetic pole heat dissipation system, this application also provides a heat dissipation magnetic pole that is used in conjunction with or included in the magnetic pole heat dissipation system disclosed in the above embodiments. The control method includes the following steps:

[0104] Step S1: Obtain the operating temperature of magnetic pole 4; it is understood that the temperature is detected in real time during the operation of magnetic pole 4, so as to prepare for the next step of controlling the oil cooling heat dissipation component 1.

[0105] Step S2: Compare the operating temperature with the first threshold. When the operating temperature is higher than the first threshold, control the active heat sink 11 to start. It can be understood that during the continuous operation of the magnetic pole 4, the temperature of the magnetic pole 4 will continue to increase. In order to ensure the working stability of the magnetic pole 4, the active heat sink 11 is started to achieve temperature regulation of the magnetic pole 4.

[0106] Based on the above embodiment, before step S1, there is also step S01: obtaining a signal that the magnetic pole 4 has started working; it can be understood that after obtaining the signal that the magnetic pole 4 has started working, temperature detection can begin so that the temperature of the magnetic pole 4 can be controlled in subsequent steps.

[0107] Based on the above embodiment, after step S01 and before step S1, step S02 is also included: after obtaining the signal that the magnetic pole 4 has started working, the circulation pump 10 is controlled to start. It can be understood that when the magnetic pole 4 starts working, the circulation pump 10 is started, which can pump the low-temperature cooling oil to the magnetic pole 4 to cool the magnetic pole 4. In the embodiment where a passive air-cooled radiator 20 is set, the passive air-cooled radiator 20 is used for initial heat dissipation. When the passive heat dissipation cannot meet the temperature requirements, the active radiator 11 is started to achieve heat dissipation compensation.

[0108] Based on the above embodiments, after step S2, the method further includes:

[0109] Step S3: Obtain the target working state, and control the switching of several injection sub-control valves 14, discharge sub-control valves 15 and emergency sub-control valves 17 according to the working state; it can be understood that by controlling the valves, the working state of the above magnetic pole heat dissipation system can be selected, such as the above emergency working state or the inefficient oil cooling working state, so as to cope with different working conditions.

[0110] Based on the above embodiment, after step S01, the method further includes: step S03: obtaining the working state of several magnetic poles 4, and the working state of the magnetic poles 4 includes normal state and fault state; if the magnetic poles 4 are in normal state, then jump to step S1 or step S02; if the magnetic poles 4 are in fault state, then jump to step S3.

[0111] It is understandable that when all magnetic poles 4 are working normally, heat dissipation can be carried out normally for all magnetic poles 4. However, when one or more magnetic poles 4 fail, the system switches to control the valves configured in the above-mentioned magnetic pole heat dissipation system to regulate and block the injection ports 42 and discharge ports 43 of the failed magnetic pole 4.

[0112] It should be noted that the method of obtaining the working status of several magnetic poles 4 is not limited, as long as the functional requirements are met. For example, in some embodiments, the control unit has an input structure, which can be a button or a touch screen or keyboard used in conjunction with control software that can perform the above steps, so that fault control signals can be manually input, causing the controller 3 to perform the above step S03; or, in some embodiments, the above magnetic pole heat dissipation system is equipped with a pressure sensor, which is used to detect the pressure at the magnetic pole 4 injection port 42 and the pressure at the magnetic pole 4 discharge port 43. If the pressure at the discharge port 43 is lower than the pressure at the magnetic pole 4 injection port 42, then the magnetic pole 4 has a leakage fault.

[0113] Based on the above embodiment, step S1 further includes: obtaining the cooling temperature at the outlet end of the passive air-cooled radiator 20; step S2 further includes: comparing the cooling temperature with a second threshold, and controlling the active radiator 11 to start when the cooling temperature is higher than the second threshold. It can be understood that, similarly to the scheme of controlling the start of the active radiator 11 based on the operating temperature of the magnetic pole 4, during the continuous operation of the magnetic pole 4, the temperature of the magnetic pole 4 will continuously increase. Since the heat dissipation efficiency of the passive air-cooled radiator 20 is limited, when the operating temperature of the magnetic pole 4 is too high, after the cooling oil flows through the passive air-cooled radiator 20 for initial heat dissipation, if the temperature of the cooling oil flowing out of the passive air-cooled radiator 20 is still high, the active radiator 11 can be started to ensure the working stability of the magnetic pole 4, thereby achieving temperature regulation of the magnetic pole 4. It should be noted that controlling the start of the active radiator 11 based on the cooling temperature at the outlet end of the passive air-cooled radiator 20 and based on the operating temperature of the magnetic pole 4 can be either selected or set simultaneously.

[0114] In some embodiments, such as Figure 2 , Figure 5 , Figure 8 , Figure 11 As shown, temperature sensors are installed at both the inlet and outlet of the passive air-cooled radiator 20 to facilitate the detection of hydraulic oil temperature.

[0115] It should be noted that the relational terms such as "first" and "second" mentioned above are only used to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities; the terms "upper surface," "lower surface," "top," and "bottom" as well as the directional terms "upper," "lower," "left," and "right" mentioned above are defined based on the accompanying drawings in the specification.
