[0015] In view of the influence of working heat of the electromagnet of the high-speed maglev train, the present invention takes a different approach and proposes a cooling device that can meet the working temperature requirements of the magnetic pole.

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] Without loss of generality, this embodiment uses the illustrated magnetic pole winding as the basis for description to describe in detail the heat dissipation and cooling solution for the magnetic pole proposed in this application. As an exemplary illustration, the specific structure of the magnetic pole winding and the ratio of its wire turn sizes do not constitute a substantial limitation on the scope of protection claimed in this application.

[0037] See also Figure 1 and Figure 2 ,in, Figure 1 is a schematic diagram of the overall structure of the magnetic pole cooling device according to this embodiment, Figure 2 This is a schematic diagram of the magnetic pole cooling device from another perspective.

[0038] As shown in the figure, the magnetic pole cooling device 10 includes a cooling component 1, an inlet liquid distributor 2, an outlet liquid distributor 3 and a cold source component 4. Among them, a plurality of cooling components 1 arranged between the turns are used as a basic heat exchange structure, which is used to perform heat exchange with the magnetic pole winding 201, and establish a cooling cycle with the cold source component 4 through the inlet liquid distributor 2 and the outlet liquid distributor 3.

[0039] In order to clearly illustrate the specific configuration position and action mechanism of the cooling component 1, the three cooling components 1 shown in the figure are taken as an example to explain in detail their specific structure and connection relationship.

[0040] In this solution, multiple cooling components 1 are respectively arranged between adjacent turns of the magnetic pole winding 201, and the cooling components 1 are made of insulating material to avoid affecting the electromagnetic performance of the magnetic pole. Figure 3 and Figure 4 ,in, Figure 3 for Figure 2 A top view of Figure 4 for Figure 3 Enlarged view of part C.

[0041] Combination Figure 3 and Figure 4 As shown, each cooling component 1 has an internal flow channel 11 and an inlet 12 and an outlet 13 connected to the internal flow channel 11, and is configured as follows: the body of each cooling component 1 is bent in accordance with the winding trend of the pole winding 201, and fits with the surface of the adjacent turns, so as to fully exchange the heat generated by the pole to the cooling medium and quickly take it away through the cooling cycle.

[0042] like Figure 2 As shown, the cooling component 1 body is not fitted along the entire surface of the wire turns, that is, a certain space is reserved at the inlet 12 and the outlet 13 to facilitate assembly. It should be understood that the fitting area between the cooling component 1 body and the wire turn surface is related to the actual heat exchange amount. In other words, the fitting area between the two can be determined according to the actual product design needs, as long as the use needs of reasonable temperature control are met.

[0043] Among them, the inlet liquid distributor 2 and the outlet liquid distributor 3 are both equipped with a collection port and multiple branch ports to establish a connection relationship between the main circulation path and each cooling branch. Figure 5 , Figure 6 and Figure 7 ,in, Figure 5 for Figure 1 Bottom view of Figure 6 for Figure 3 A-direction view, Figure 7 for Figure 3 B view.

[0044] As shown in the figure, corresponding to the three cooling components 1, the inlet liquid distributor 2 has three branch ports 221 connected to its collection port 211, and each branch port 221 corresponds to and is connected to the inlet 12 of the corresponding cooling component 1; the outlet liquid distributor 3 has three branch ports 321 connected to its collection port 311, and each branch port 321 corresponds to and is connected to the outlet 13 of the corresponding cooling component 1. Among them, the collection port 211 of the inlet liquid distributor 2 is connected to the medium output port 41 of the cold source component 1 through a pipeline, and the collection port 311 of the outlet liquid distributor 3 is connected to the medium input port 42 of the cold source component 1 through a pipeline.

[0045] During operation, the medium output by the cold source component 4 enters each cooling component 1 through the inlet liquid distributor 2. During the medium flowing through the internal flow channel 11, it exchanges heat with the turns on both sides to cool the magnetic pole, and then flows back to the cold source component 4 after being collected through the outlet liquid distributor 3. In this cycle, magnetic stage heat dissipation cooling is achieved. In a specific implementation, the inlet liquid distributor 2 and the outlet liquid distributor 4 are both made of insulating materials to avoid affecting the electromagnetic performance of the magnetic pole.

[0046] In this embodiment, the inlet liquid distributor 2 and the outlet liquid distributor 3 are both configured with a tubular body, and the collecting port is opened on the tubular body. A plurality of spaced-apart plate-like flow channel bodies are arranged on the tubular body, and each plate-like flow channel body forms a corresponding branch port.

[0047] Specific as Figure 6 and Figure 7 As shown, the collection port 211 of the inlet liquid distributor 2 is provided on its tubular body 21, and three plate-like flow channel bodies 22 extend toward the cooling component 1, and corresponding branch ports 221 are formed at their extended ends. The collection port 311 of the outlet liquid distributor 3 is provided on its tubular body 31, and three plate-like flow channel bodies 32 extend toward the cooling component 1, and corresponding branch ports 321 are formed at their extended ends.

[0048] Here, "extended end" refers to the outer end of each plate-like flow channel body away from the corresponding tubular body. It should be noted that the specific implementation of the inlet liquid distributor 2 and the outlet liquid distributor 3 is not limited to the structural form shown in the figure. As long as it can meet the functional needs of the inlet liquid diversion and outlet liquid confluence of each cooling component 1, it is within the scope of protection requested by this application. In comparison, the design method of arranging multiple plate-like flow channel bodies on the tubular body is simple and reliable in structure, and has good processing technology.

[0049] In this embodiment, the cold source component 4 can be a condenser. For example, but not limited to, the following refrigeration cycle is established. The liquid refrigerant is sent out through the medium output port 41, sent to the cooling component 1 and evaporated therein to form a refrigerant vapor, and then sent back to the condenser through the medium input port 42 to release heat to form a liquid refrigerant, thereby completing the refrigeration cycle.

[0050] Of course, the cold source component 4 can also be a liquid cooling cycle established in the form of other media, such as water, liquid nitrogen or air. It is understandable that the working mechanism of the liquid cooling cycle is not the core invention of this application, and those skilled in the art can implement it based on the existing technology, so it will not be repeated in this article.

[0051] Furthermore, the magnetic pole cooling device 10 also includes a control component 5, which can control the power regulation of the condenser according to the control strategy to adaptively adjust the refrigeration capacity of the condenser and control the temperature of the output cooling medium. The control component 5 can be specifically a data acquisition analyzer equipped with a storage unit and a data processing unit to execute the corresponding control strategy.

[0052] As shown in the figure, a flow pump 6 is provided on the path connected to the medium input port 42, and the control component 5 can be used to control the flow rate of the flow pump 6. Here, the implementation method of the "flow pump" is not the core invention of this application, and the specific method can be to select a pump type with adjustable flow rate. Of course, the flow pump 6 can also be provided on the path connected to the medium output port 41, which is equivalent to realizing the medium flow rate participating in heat exchange in the system circulation by controlling the medium reflux flow rate.

[0053] In order to achieve more accurate magnetic pole temperature control, the present solution further utilizes the temperature sensor 7 to collect the medium temperature signal, and utilizes the flow sensor 8 to collect the medium flow signal.

[0054] like Figure 5As shown, in this scheme, two temperature sensors 7 are provided, which are used to collect the inlet temperature and outlet temperature of the cooling component 1 respectively. One temperature sensor 7 is provided on the tubular body 21 of the inlet liquid distributor 2, and the other temperature sensor 7 is provided on the tubular body 31 of the outlet liquid distributor 3. The flow sensor 8 is used to collect the medium flow of the medium output port 41, and is specifically provided at the output port of the flow pump 6, and feeds back the flow signal to the control component 5 in real time. Based on this, the control component 5 outputs a control signal to the control end of the flow pump 6 and the condenser (4) according to the collected temperature signal and flow signal, please refer to Figure 8 , which shows a block diagram of the control principle of the magnetic pole cooling device described in this embodiment.

[0055] In other specific applications, for application scenarios with different power parameters, in order to achieve the temperature control accuracy requirements required for specific control, the inlet and outlet temperatures of the cooling component 1 can be preferably collected according to the actual situation, or one of the temperatures can be selected for temperature collection. The inlet and outlet liquid flow rates of the liquid cooling cycle can also be collected at the same time, rather than being limited to the medium flow rate of the medium output port 41 as the basic control data as shown in the figure.

[0056] In this embodiment, the control component 5 uses the temperature signal representing the outlet temperature of the cooling component 1 being greater than the first temperature threshold as the first judgment condition, obtains the judgment result that the magnetic pole needs to be cooled, and outputs the first control instruction to the control end of the flow pump 6 and the condenser (4) respectively, so as to increase the power of the condenser and the pumping flow of the flow pump 6, thereby improving the heat exchange capacity of the system. Thus, a closed-loop control is formed, and the magnetic pole temperature control is performed in real time.

[0057] Furthermore, after the control component 5 outputs the first control instruction, the second judgment condition is that the temperature signal representing the outlet temperature of the cooling component 1 is greater than the second temperature threshold, and a judgment result that the magnetic pole needs to continue to be cooled is obtained, and the second temperature threshold is not lower than the above-mentioned first temperature threshold. In other words, the second temperature threshold is greater than the first temperature threshold or equal to the first temperature threshold.

[0058] When the judgment result that the magnetic pole needs to continue to be cooled is obtained, the second control instruction is output to the control end of the flow pump 6 and the condenser (4) respectively, so as to continue to increase the power of the condenser and the pumping flow of the flow pump, and continue to improve the heat exchange capacity of the system; at the same time, an alarm signal is issued, and a corresponding alarm is issued through the alarm signal, so as to make a prediction and processing in advance, and ensure that the magnetic pole is always kept at an appropriate temperature.

[0059] In this way, the temperature control strategy includes two levels of control. One is that when the temperature signal of the outlet temperature of the cooling component 1 is greater than the first temperature threshold, it indicates that the pole temperature is too high and needs to be cooled down. The other is to monitor the data returned by the temperature sensor to determine whether the pole is effectively cooled down. If the temperature signal of the outlet temperature of the cooling component 1 is greater than the second temperature threshold, if the temperature returned by the temperature sensor is still too high, the power of the condenser will continue to increase while increasing the flow rate of the flow pump, and an alarm signal will be issued. If the returned temperature returns to a safe range, the power of the condenser will be gradually reduced while reducing the flow rate of the flow pump until the default value is reached.

[0060] In this solution, the inlet 12 and outlet 13 of each cooling component 1 are located at the bottom. Figure 1 and Figure 2 In order to establish a reliable heat exchange cycle, at least the inlet 12 is located at the bottom of the cooling component 1, so that even when each cooling component 1 is not completely filled with liquid cooling medium, a reliable cooling and heat dissipation capacity can be achieved.

[0061] In addition to the magnetic pole cooling device 10, this embodiment also provides a permanent conductive magnet, including an iron core 202 and a magnetic pole winding 201 wound on the iron core 202 to form a magnetic pole, and also includes the aforementioned magnetic pole cooling device, at least part of the adjacent turns of the magnetic pole winding 201 have a receiving spacing, and a receiving spacing is configured every several tightly wound turns; that is, when winding, a certain space is reserved every several turns for installing the cooling component 1. The receiving spacing and the number of cooling components 1 can be determined according to the power of the actual permanent conductive magnet. After assembly, each cooling component 1 of the magnetic pole cooling device 10 is set in the receiving spacing between the corresponding adjacent turns and fits the surface of the adjacent turns respectively.

[0062] In addition to the aforementioned magnetic pole cooling device and the normally conductive magnet, the present embodiment further provides a maglev train, which uses the normally conductive magnet with the magnetic pole cooling device as described above, and can realize real-time monitoring and control of the magnetic pole temperature to ensure that the insulation performance between the magnetic pole windings is not affected by the temperature increase, thereby extending the service life of the magnetic pole. It should be understood that the other functional components of the maglev train are not the core invention of this application, and those skilled in the art can realize them based on the existing technology, and will not be described in detail herein.

[0063] It should be noted that in the above-mentioned embodiments provided in this embodiment, the structural form of the cooling component 1 needs to adapt to the specific form of the pole winding, such as but not limited to a roughly rectangular pole winding formed by winding a metal sheet. It should be understood that as long as the core concept is consistent with this solution, it is within the scope of protection requested in this application.

[0064] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
