Description

Technical Field

[0001] This application relates to the field of electromagnetic pumps, and particularly to an induction electromagnetic pump. Background Art

[0002] An induction electromagnetic pump is a pump that uses the principle of electromagnetic induction to drive the flow of conductive liquid metal, and is commonly used in the liquid metal cooling system in the nuclear industry and other fields that require non-mechanical contact to drive metal liquids. When the existing induction electromagnetic pump transports liquid metal, an alternating current is generally applied to multiple windings arranged on the iron core to generate an alternating magnetic field. An eddy current is induced in the liquid metal through the alternating magnetic field, and then the Lorentz force is generated by the interaction between the eddy current and the magnetic field, thereby pushing the liquid metal to flow in a specific direction in the pipeline, and further realizing the non-contact transmission of the liquid metal.

[0003] However, the windings of the existing induction electromagnetic pump have relatively long ends, resulting in a large gap at the connection between the ends and the iron core, which reduces the slot fill factor of the induction electromagnetic pump, thereby reducing the space utilization rate of the induction electromagnetic pump. At the same time, windings need to be arranged on both sides of the pipeline to generate a magnetic field to drive the liquid metal to flow, which reduces the power density of the induction electromagnetic pump, and further reduces the performance of the induction electromagnetic pump.

[0025] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the specific embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application.

[0027] The singular forms of "a", "the" and "said" used in the description and claims of the present application are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and includes any and all possible combinations of one or more of the associated listed items.

[0028] In order to clearly illustrate the technical solution of the present application, the front, rear, left, right, upper and lower are also defined as Figure 1 shown, to represent the front, rear, left, right, upper and lower of the induction electromagnetic pump 100.

[0029] As Figure 1 and Figure 2As shown in the figure, the present application provides an induction electromagnetic pump 100. The induction electromagnetic pump 100 extends along a first preset direction 101, and the induction electromagnetic pump 100 includes a mounting iron core 11, an annular winding 12, a first flow channel 13, a second flow channel 14, a first iron core 15, and a second iron core 16. The mounting iron core 11 is the main structure of the induction electromagnetic pump 100 and is used to support the annular winding 12, the first flow channel 13, the second flow channel 14, the first iron core 15, and the second iron core 16. The first flow channel 13 and the second flow channel 14 are respectively arranged on both sides of the mounting iron core 11 and are used to convey liquid metal. The annular winding 12 is arranged inside the mounting iron core 11. The first iron core 15 is connected to the first flow channel 13 and is used to cooperate with a plurality of annular windings 12 to generate a magnetic circuit. The second iron core 16 is connected to the second flow channel 14 and is also used to cooperate with a plurality of annular windings 12 to generate a magnetic circuit.

[0030] After an alternating current passes through the annular winding 12, a traveling magnetic field can be generated, and the traveling magnetic field extends along the distribution direction of the annular winding 12. After the traveling magnetic field is generated, the first iron core 15 and the second iron core 16 will guide the traveling magnetic field to extend from one end of the first iron core 15 and the second iron core 16 to the other end of the first iron core 15 and the second iron core 16, and then return from the other end of the first iron core 15 and the second iron core 16 to one end of the first iron core 15 and the second iron core 16, thereby forming a closed magnetic circuit. Moreover, the traveling magnetic field will induce eddy currents in the liquid metal in the first flow channel 13 and the second flow channel 14, and the interaction between the eddy currents and the magnetic field will generate a Lorentz force, thereby pushing the liquid metal to flow along the extension direction of the first flow channel 13 or the second flow channel 14.

[0031] It should be noted that in the present application, the first preset direction 101 is Figure 1 the left - right direction of the induction electromagnetic pump 100 in the figure.

[0032] Specifically, the mounting iron core 11 includes a plurality of vertical portions 111 and a plurality of horizontal portions 112. The plurality of vertical portions 111 all extend along a second preset direction 102, and the plurality of vertical portions 111 are arranged at equal intervals. Among them, the second preset direction 102 is perpendicular to the first preset direction 101. In the present application, the second preset direction 102 is Figure 1 the up - down direction of the induction electromagnetic pump 100 in the figure.

[0033] The plurality of horizontal portions 112 and the plurality of vertical portions 111 are integrally formed. Each horizontal portion 112 extends along the first preset direction 101. Each horizontal portion 112 is located between two adjacent vertical portions 111. Each horizontal portion 112 connects the middle parts of two adjacent vertical portions 111, so that each horizontal portion 112 and two adjacent vertical portions 111 form an "H" - shaped structure.

[0034] With the above settings, the installation iron core 11 is arranged as a plurality of connected "H" - shaped structures, so that the winding is wound around each transverse part 112 to form an annular winding 12. Thus, the annular winding 12 can be arranged on the installation iron core 11, thereby shortening the length of the winding end, reducing the copper loss of the winding during operation, and further improving the performance of the induction electromagnetic pump 100 during operation.

[0035] At the same time, the plurality of vertical parts 111 are arranged at equal intervals, which can make the length of each transverse part 112 equal. Thus, each annular winding 12 arranged on the transverse part 112 has the same size, improving the uniformity of the current distribution in each annular winding 12, further improving the uniformity of the magnetic field generated by the induction electromagnetic pump 100, which is beneficial to improving the stability of the electromagnetic force driving the flow of the liquid metal, and thus improving the performance of the induction electromagnetic pump 100.

[0036] Moreover, since each annular winding 12 has the same size, it can also prevent the heat generated by a single annular winding 12 from being too large, thus avoiding the situation of local overheating of the induction electromagnetic pump 100, which is beneficial to extending the service life of the induction electromagnetic pump 100.

[0037] In addition, each annular winding 12 is sleeved on a transverse part 112, that is, one annular winding 12 is arranged on each "H" - shaped structure. Each annular winding 12 is located between two adjacent vertical parts 111. Both side surfaces of each annular winding 12 along the first preset direction 101 are flat, and the two side surfaces of each annular winding 12 are respectively attached to two adjacent vertical parts 111.

[0038] Through the above settings, the gap between each annular winding 12 and the transverse part 112 and the vertical part can be reduced, thereby reducing the occupied space of the annular winding 12 on the installation iron core 11 and improving the space utilization rate of the induction electromagnetic pump 100. At the same time, arranging the annular winding 12 with flat side surfaces between two adjacent vertical parts 111 can fill the gap between adjacent vertical parts 111 to the maximum extent, thereby improving the slot - filling rate of the induction electromagnetic pump 100 and improving the space utilization rate of the induction electromagnetic pump 100.

[0039] In this application, the first flow channel 13 is used to transport liquid metal, and the first flow channel 13 is connected to a plurality of vertical parts 111. The second flow channel 14 is used to transport liquid metal, and the second flow channel 14 is connected to a plurality of vertical parts 111. The second flow channel 14 and the first flow channel 13 are located on both sides of the plurality of vertical parts 111 along the second preset direction 102.

[0040] Specifically, along the up-down direction of the induction electromagnetic pump 100, the first flow channel 13 is located above the plurality of vertical portions 111, and the second flow channel 14 is located below the plurality of vertical portions 111. Through the above arrangement, the first flow channel 13 and the second flow channel 14 are arranged on both sides of the mounting core 11, so that the electromagnetic thrust generated by the annular winding 12 can simultaneously drive the liquid metal in the first flow channel 13 and the second flow channel 14 to flow, thereby improving the working efficiency of the induction electromagnetic pump 100 and improving the performance of the induction electromagnetic pump 100.

[0041] In this embodiment, the first core 15 is located on a side of the first channel 13 away from the vertical portion 111 and connected to the first channel 13. The second core 16 is located on a side of the second channel 14 away from the vertical portion 111 and connected to the second channel 14.

[0042] Through the above-mentioned arrangement, the first iron core 15 and the second iron core 16 are arranged. Since no winding is installed in the first iron core 15 and the second iron core 16, the heat dissipation requirement is not high. Therefore, the distance between the first iron core 15 and the first flow channel 13 can be shortened, and the distance between the second iron core 16 and the second flow channel 14 can be shortened, thereby reducing the distance between the installation iron core 11 and the first iron core 15, and reducing the distance between the installation iron core 11 and the second iron core 16, thereby increasing the magnetic induction intensity and the induced current density in the first flow channel 13 and the second flow channel 14, so as to increase the output pressure and the overall power density of the induction electromagnetic pump 100, thereby improving the performance of the induction electromagnetic pump 100.

[0043] More specifically, the present application also provides a comparison table of the output pressures of the induction electromagnetic pump 100 and the electromagnetic pumps in the prior art at the same copper loss.

[0044]

[0045] As shown in the table above, when the speed is between 0m / s and 6m / s, the output pressure of the induction electromagnetic pump 100 of the present application is 80447Pa to 57732Pa, while the output pressure of the electromagnetic pump in the prior art is 36302Pa to 16393Pa. Therefore, under the same copper consumption, compared with the electromagnetic pump in the prior art, the pressure output by the induction electromagnetic pump 100 of the present application is basically twice that of the electromagnetic pump in the prior art. In addition, the induction electromagnetic pump 100 is provided with two flow channels, which can increase the flow rate of liquid metal per unit time on the basis of increasing the output pressure, thereby improving the performance of the induction electromagnetic pump 100.

[0046] As an implementation manner, two mounting grooves 17 are formed between each transverse portion 112 and two adjacent vertical portions 111, and the two mounting grooves 17 are located on both sides of the transverse portion 112 along the second preset direction 102. Each annular winding 12 includes two straight segments 121 and two curved segments 122. One curved segment 122 is connected to one ends of the two straight segments 121, and the other curved segment 122 is connected to the other ends of the two straight segments 121. The two straight segments 121 are respectively located in the corresponding two mounting grooves 17.

[0047] Through the above arrangement, each annular winding 12 can be wound between the corresponding two mounting grooves 17. In the present application, each annular winding 12 is arranged in a racetrack shape, which can increase the number of turns of the annular winding 12, thereby reducing the current in the annular winding 12, further reducing the copper loss of the annular winding 12, so as to reduce the loss of the induction electromagnetic pump 100, and thus improve the efficiency of the induction electromagnetic pump 100. At the same time, increasing the number of turns of the annular winding 12 can also increase the magnetic field strength of the annular winding 12, thereby generating a greater electromagnetic force, which is beneficial to improving the efficiency of promoting the transmission of the liquid metal in the first flow channel 13 and the second flow channel 14, and further improving the performance of the induction electromagnetic pump 100.

[0048] It should be noted that in the present application, the structure of the annular winding 12 is not limited, and it only needs to meet the requirement of improving the performance of the induction electromagnetic pump 100.

[0049] As an implementation manner, each straight segment 121 is in contact with the groove wall 171 and the groove bottom 172 of the corresponding mounting groove 17. Through the above arrangement, the annular winding 12 can be in direct contact with the mounting groove 17, which is beneficial to the annular winding 12 transmitting the heat generated inside to the outside during operation, thereby avoiding overheating inside the induction electromagnetic pump 100, thus prolonging the service life of the annular winding 12 and prolonging the service life of the induction electromagnetic pump 100. At the same time, each straight segment 121 being in contact with the groove wall 171 and the groove bottom 172 of the corresponding mounting groove 17 can also reduce the gap between the annular winding 12 and the mounting groove 17, which is beneficial to improving the slot filling rate of the induction electromagnetic pump 100, and further improving the performance of the induction electromagnetic pump 100.

[0050] As an implementation manner, the two side surfaces of the two straight segments 121 along the first preset direction 101 are both planes, the two side surfaces of the two curved segments 122 along the first preset direction 101 are both planes, and the side surfaces on the same side of the two straight segments 121 and the two curved segments 122 are all in the same plane.

[0051] Through the above settings, the contact surface between the straight segment 121 and the installation groove 17 can be made flat, and the contact surface between the curved segment 122 and the installation groove 17 can be made flat. At the same time, the contact surface between the straight segment 121 and the installation groove 17 and the contact surface between the curved segment 122 and the installation groove 17 are both in the same plane, so as to improve the tightness when the annular winding 12 fits against the groove wall 171 and the groove bottom 172 of the installation groove 17, so as to avoid leaving a large gap when the annular winding 12 is arranged in the installation groove 17, and further improve the slot fill factor of the installation iron core 11, so as to improve the space utilization rate of the induction electromagnetic pump 100.

[0052] At the same time, with the improvement of the slot fill factor of the installation iron core 11, the number of turns of the annular winding 12 arranged in the installation iron core 11 per unit space can be increased, so as to increase the magnetic field strength, and further increase the power density of the induction electromagnetic pump 100, so as to improve the performance of the induction electromagnetic pump 100.

[0053] As an implementation manner, the slot openings 173 of the installation grooves 17 all face away from the transverse portion 112. In the present application, the slot openings 173 are located at the connection between the vertical portion 111 and the first flow channel 13 or the second flow channel 14.

[0054] Through the above settings, sufficient space can be provided for the installation iron core 11, so that more turns of the annular winding 12 can be arranged in the installation groove 17, so that a stronger magnetic field can be generated during the operation of the annular winding 12, and further increase the power density of the induction electromagnetic pump 100, so as to improve the performance of the induction electromagnetic pump 100.

[0055] As an implementation manner, the maximum span of the plurality of annular windings 12 along the first preset direction 101 is the winding span L1, and the maximum length of the installation iron core 11 along the first preset direction 101 is the iron core length L2. The ratio of the winding span to the iron core length is greater than or equal to 0.7 and less than 1. Specifically, the ratio of the winding span to the iron core length is greater than or equal to 0.75 and less than or equal to 0.95. More specifically, the ratio of the winding span to the iron core length is greater than or equal to 0.8 and less than or equal to 0.9. In the present application, an equal spacing is provided between adjacent annular windings 12, and the extending directions of the plurality of annular windings 12 and the extending direction of the installation iron core 11 both extend along the first preset direction 101, that is Figure 1 the left-right direction of the induction electromagnetic pump 100 in

[0056] Through the above settings, it is possible to avoid too small a ratio of the winding span to the length of the mounting iron core 11, which is conducive to increasing the set length of the annular winding 12 in the first preset direction 101. Since the first flow channel 13 and the second flow channel 14 are arranged on both sides of the mounting iron core 11 in the second preset direction 102, and both the first flow channel 13 and the second flow channel 14 extend along the first preset direction 101, the electromagnetic force generated by the annular winding 12 can fully and evenly act on the liquid metal in the first flow channel 13 and the second flow channel 14, which is conducive to the transmission of the liquid metal in the first flow channel 13 and the second flow channel 14, thereby improving the working efficiency of the induction electromagnetic pump 100 and improving the performance of the induction electromagnetic pump 100.

[0057] At the same time, it can also make the annular winding 12 fill the installation groove 17 in the first preset direction 101 of the mounting iron core 11, thereby improving the slot fill factor of the induction electromagnetic pump 100 and improving the space utilization rate of the induction electromagnetic pump 100. In addition, the increase in the slot fill factor of the mounting iron core 11 can increase the number of turns of the annular winding 12 arranged in the unit space of the mounting iron core 11, thereby increasing the magnetic field strength and further increasing the power density of the induction electromagnetic pump 100 to improve the performance of the induction electromagnetic pump 100.

[0058] As an implementation manner, the induction electromagnetic pump 100 further includes a plurality of short-circuit bars 18, and the plurality of short-circuit bars 18 are respectively located at the following positions: both sides of the first flow channel 13 along the third preset direction 103, both sides of the second flow channel 14 along the third preset direction 103, and the third preset direction 103 is perpendicular to the first preset direction 101 and the second preset direction 102. In this application, the third preset direction 103 is the Figure 1 front-back direction of the induction electromagnetic pump 100 in this application, and in this application, the short-circuit bar 18 can be a high-conductivity metal part.

[0059] Exemplarily, in this application, the material of the short-circuit bar 18 can be copper. The short-circuit bar 18 made of copper can enhance the electromagnetic force exerted by the annular winding 12 on the first flow channel 13 or the second flow channel 14, thereby improving the stability and efficiency of the transmission of the liquid metal in the first flow channel 13 or the second flow channel 14, and thus improving the performance of the induction electromagnetic pump 100.

[0060] It should be noted that this application does not limit the material of the short-circuit bar 18, and only needs to meet high conductivity.

[0061] With the above settings, the short - circuit bar 18 can improve the electrical conductivity of the first flow channel 13 and the second flow channel 14, so as to improve the stability of the electromagnetic force acting in the first flow channel 13 and the second flow channel 14. Thus, after the liquid metal is affected by the electromagnetic force, it can be avoided that the liquid metal flows irregularly in a circular direction in the first flow channel 13 or the second flow channel 14. Furthermore, the flow path of the liquid metal flows sequentially along multiple juxtaposed rectangular directions, so as to improve the stability of the liquid metal transmission, and further improve the performance of the induction - type electromagnetic pump 100. In addition, in the present application, the connection mode between the short - circuit bar 18 and the first flow channel 13 and the connection mode between the short - circuit bar 18 and the second flow channel 14 can be welding or adhesive bonding.

[0062] Exemplarily, the adhesive can be an epoxy resin adhesive. The epoxy resin adhesive has strong connection strength and hardness, which can improve the stability when the short - circuit bar 18 is connected to the first flow channel 13 or the second flow channel 14.

[0063] It should be noted that the present application does not limit the installation method of the short - circuit bar 18 and the material of the adhesive, and only needs to meet the connection strength between the short - circuit bar 18 and the first flow channel 13 or the second flow channel 14.

[0064] As an implementation manner, both the first flow channel 13 and the second flow channel 14 extend along the first preset direction 101. The openings of the first flow channel 13 are located on both sides of the first flow channel 13 along the first preset direction 101, and the openings of the second flow channel 14 are located on both sides of the first flow channel 13 along the first preset direction 101.

[0065] Through the above settings, it can be made that the setting direction and the opening direction of the first flow channel 13 and the second flow channel 14 are adapted to the setting direction of the annular winding 12. Thus, the acting direction of the electromagnetic force generated by the annular winding 12 is the same as the setting direction and the opening direction of the first flow channel 13 and the second flow channel 14, so as to reduce the resistance generated when the liquid metal flows in the first flow channel 13 and the second flow channel 14 under the action of the electromagnetic force, and further improve the transmission efficiency of the liquid metal in the first flow channel 13 and the second flow channel 14, so as to improve the performance of the induction - type electromagnetic pump 100.

[0066] As Figure 3 and Figure 4 shown, as an implementation manner, the present application provides the magnetic field distribution diagrams of the induction - type electromagnetic pump 100 and the electromagnetic pump in the prior art. Figure 3 It is the magnetic field distribution diagram of the electromagnetic pump in the prior art, Figure 4 and it is the magnetic field distribution diagram of the induction - type electromagnetic pump 100 of the present application. Through Figure 3 and Figure 4By comparison, the magnetic field of the electromagnetic pump in the prior art is mainly concentrated in the middle section of the iron core. Therefore, there will be a problem that the magnetic field in the middle is strong and the magnetic fields on both sides are weak, which makes the electromagnetic force on the liquid metal unstable, thus affecting the stability of the liquid metal transmission. In contrast, the magnetic field intensity distribution at various positions of the installation iron core 11 of the induction type electromagnetic pump 100 is relatively uniform, which can make the electromagnetic force on the liquid metal during transmission relatively uniform, so as to improve the stability of the liquid metal transmission.

[0067] As Figure 5 and Figure 6 shown, as an implementation manner, the induction type electromagnetic pump 100 includes a pole shoe 19, and the pole shoe 19 is made of silicon steel sheets 191, or the pole shoe 19 is formed by stacking a plurality of silicon steel sheets 191. Among them, the pole shoe 19 is used to enhance the linearity of the traveling magnetic field, thereby improving the uniformity of the traveling magnetic field, so as to improve the stability of the liquid metal transmission under the action of the traveling magnetic field, and further improve the operating stability of the induction type electromagnetic pump 100.

[0068] It should be noted that when the pole shoe 19 is formed by stacking a plurality of silicon steel sheets 191, adjacent two silicon steel sheets 191 are bonded by insulating glue, so as to achieve electrical insulation between adjacent two silicon steel sheets 191, block the flow of eddy current between adjacent two silicon steel sheets 191, shorten the path of the eddy current flow, and further reduce the eddy current loss of the induction type electromagnetic pump 100.

[0069] It should be noted that the form of stacking a plurality of silicon steel sheets 191 can make the thickness of the pole shoe 19 meet the magnetic conduction requirements, so as to improve the operating stability of the induction type electromagnetic pump 100. At the same time, on the basis of meeting the thickness of the pole shoe 19 in the radial direction, the thickness of a single silicon steel sheet 191 in the radial direction can be reduced, so as to reduce the induced electromotive force accumulated on a single silicon steel sheet 191, reduce the eddy current value during magnetic conduction of the pole shoe 19, and further reduce the eddy current loss of the induction type electromagnetic pump 100.

[0070] Exemplarily, the pole shoe 19 is installed on one side of the first flow channel 13 close to the installation iron core 11, and / or the pole shoe 19 is installed on one side of the second flow channel 14 close to the installation iron core 11. Specifically, the pole shoe 19 is located between the first flow channel 13 and a plurality of vertical parts 111, and / or the pole shoe 19 is located between the second flow channel 14 and a plurality of vertical parts 111.

[0071] It should be noted that the pole shoe 19 is bonded to the first flow channel 13 by insulating glue, and the pole shoe 19 is bonded to the second flow channel 14 by insulating glue, so as to avoid short circuit between the outer walls of the first flow channel 13 and the second flow channel 14, and ensure the structural strength of the pole shoe 19.

[0072] In addition, installing the pole shoe 19 on the first flow channel 13 and / or the second flow channel 14 can improve the uniformity of the traveling magnetic field acting on the first flow channel 13 and / or the second flow channel 14, thereby enhancing the stability of the liquid metal flowing in the first flow channel 13 and / or the second flow channel 14 under the action of the traveling magnetic field, so as to improve the stability of the induction electromagnetic pump 100 for transporting the liquid metal.

[0073] In this embodiment, one pole shoe 19 corresponds to two adjacent vertical portions 111. The pole shoe 19 is formed by two silicon steel sheets 191 distributed along the first preset direction 101, and there is a gap between the two silicon steel sheets 191 along the first preset direction 101, so that a semi-open slot is formed between the pole shoe 19 and the two adjacent vertical portions 111. Alternatively, the pole shoe 19 is formed by two groups of silicon steel sheets 191 distributed along the first preset direction 101. Each group of silicon steel sheets 191 is stacked by a plurality of silicon steel sheets 191, and there is a gap between the two groups of silicon steel sheets 191 along the first preset direction 101, so that a semi-open slot is formed between the pole shoe 19 and the two adjacent vertical portions 111.

[0074] Through the above arrangement, there is a gap between two adjacent groups of silicon steel sheets 191 in the first preset direction 101, thereby shortening the path length of the eddy current flowing in each group of silicon steel sheets 191, reducing the eddy current loss in the pole shoe 19, and further reducing the eddy current loss of the induction electromagnetic pump 100. At the same time, setting the pole shoe 19 makes the open slot between the installation iron core 11 and the first flow channel 13 or the second flow channel 14 become a semi-open slot or a closed slot, thereby enhancing the uniformity of the magnetic field and improving the electromagnetic efficiency and performance of the induction electromagnetic pump 100.

[0075] As Figure 2 and Figure 7 shown, as an optional implementation manner, there is a gap between two adjacent pole shoes 19 along the first preset direction 101, so that a gap is formed between the two adjacent pole shoes 19. This gap can block the flow of eddy current between the two adjacent pole shoes 19, thereby shortening the path length of the eddy current flow, reducing the eddy current loss in the pole shoe 19, and thus reducing the loss during the operation of the induction electromagnetic pump 100.

[0076] It should be noted that when the pole shoe 19 is formed by two silicon steel sheets 191 distributed along the first preset direction 101, each of the above-mentioned silicon steel sheets 191 can be divided into a plurality of first silicon steel sheets 192, and there is a gap between each of the first silicon steel sheets 192. Among them, the plurality of first silicon steel sheets 192 can be distributed along the first preset direction 101, or the plurality of first silicon steel sheets 192 can be distributed along the third preset direction 103, which is not limited herein.

[0077] As Figure 2 and Figure 6As shown, as an implementation, each vertical portion 111 is provided with a plurality of first cooling holes 1111 penetrating the vertical portion 111 along a third preset direction 103. In the existing electromagnetic pump, the core teeth are surrounded by windings, so that the windings will block the core teeth, making it impossible to provide cooling holes in the above-mentioned core portion, and thus making it impossible to effectively dissipate heat from the windings during operation, which will further affect the normal operation of the windings.

[0078] With the above arrangement, since in the present application, the annular winding 12 is wound around the transverse portion 112 (i.e., the yoke portion for mounting the core 11) between two adjacent vertical portions 111, it is possible to prevent the annular winding 12 from completely wrapping the vertical portion 111 (i.e., the tooth portion of the mounting core 11), so that the first cooling holes 1111 provided in each vertical portion 111 along the third preset direction 103 will not be blocked by the annular winding 12. Thus, heat can be dissipated from the annular winding 12 through the first cooling holes 1111, further avoiding the problem of overheating when the induction electromagnetic pump 100 operates, and improving the safety of the induction electromagnetic pump 100 during operation. At the same time, by providing a plurality of first cooling holes 1111 in each vertical portion 111, the efficiency of heat transfer per unit area can be improved, thereby improving the heat dissipation efficiency of the first cooling holes 1111 for the annular winding, and further improving the safety of the induction electromagnetic pump 100 during operation.

[0079] As an implementation, each vertical portion 111 is provided with a plurality of second cooling holes 1112 penetrating the vertical portion 111 along a first preset direction 101, and each transverse portion 112 is provided with a plurality of third cooling holes (not shown in the figure) penetrating the transverse portion 112 along the first preset direction 101. The second cooling holes 1112 and the third cooling holes are arranged to overlap along the first preset direction 101, so that the second cooling holes 1112 and the third cooling holes are communicated to form a cooling through hole penetrating the mounting core 11 along the first preset direction 101. In the existing electromagnetic pump, the yoke portion of the core is arranged on one side of the winding, so that the winding cannot be fully cooled. However, in the present application, the yoke portion (i.e., the transverse portion 112) of the mounting core 11 is surrounded by the annular winding 12, so that the annular winding 12 can be fully cooled.

[0080] With the above arrangement, by providing the second cooling holes 1112 on the vertical portion 111 of the induction electromagnetic pump 100, the heat generated by the annular winding 12 between two adjacent vertical portions 111 can be transferred along the first preset direction 101. Moreover, the second cooling holes 1112 and the third cooling holes overlap in the first preset direction 101, so that the heat generated by the annular winding 12 is transferred to the external environment after passing through the second cooling holes 1112 and the third cooling holes, thus preventing the heat generated during the operation of the annular winding 12 from accumulating in the induction electromagnetic pump 100, avoiding the loss of the induction electromagnetic pump 100 due to overheating, and further improving the service life of the induction electromagnetic pump 100.

[0081] Meanwhile, by providing a plurality of second cooling holes 1112 on each vertical portion 111 and a plurality of third cooling holes on the transverse portion 112, the heat dissipation efficiency per unit area of the induction electromagnetic pump can be improved, thereby enhancing the temperature stability of the induction electromagnetic pump 100 during operation and improving the safety of the induction electromagnetic pump 100 during operation.

[0082] In addition, the second cooling holes 1112 and the third cooling holes are arranged to overlap along the first preset direction 101, and the third cooling holes penetrate through the transverse portion 112, enabling the second cooling holes 1112 on two adjacent vertical portions 111 to communicate through the third cooling holes, so as to form a cooling through-hole that penetrates the mounting iron core 11 along the first preset direction 101. The cooling through-hole can transfer heat to the outside, thereby preventing the problem of local overheating caused by the inability of some of the toroidal windings 12 to transfer excess heat to the outside during the operation of the induction electromagnetic pump 100, and further improving the safety of the induction electromagnetic pump 100 during operation.

[0083] As Figure 2 and Figure 8 shown, the present application provides an induction electromagnetic pump 100 that extends along a first preset direction 101 and includes a plurality of mounting iron cores 11, a plurality of toroidal windings 12, a first iron core 15, a second iron core 16, and a plurality of flow channels 22. The plurality of mounting iron cores 11 are distributed along a second preset direction 102. Two of the mounting iron cores 11 are defined as a first mounting iron core 113 and a second mounting iron core 114, and the other mounting iron cores 11 are all defined as third mounting iron cores 115. The plurality of third mounting iron cores 115 are located between the first mounting iron core 113 and the second mounting iron core 114 along the second preset direction 102.

[0084] Each mounting iron core 11 includes a plurality of vertical portions 111 and a plurality of transverse portions 112. The plurality of vertical portions 111 all extend along the second preset direction 102, and the plurality of vertical portions 111 are equally spaced. The second preset direction 102 is perpendicular to the first preset direction 101. The plurality of transverse portions 112 and the plurality of vertical portions 111 are integrally formed. Each transverse portion 112 extends along the first preset direction 101, and each transverse portion 112 is located between two adjacent vertical portions 111. Each transverse portion 112 connects the middle parts of two adjacent vertical portions 111, so that each transverse portion 112 and two adjacent vertical portions 111 form an "H" - shaped structure.

[0085] With the above - mentioned arrangement, the mounting iron core 11 is set as a plurality of connected "H" - shaped structures, enabling the winding to be wound around each transverse portion 112 to form a toroidal winding 12. Thus, the toroidal windings 12 can be arranged on the mounting iron core 11, thereby shortening the length of the winding ends, reducing the copper loss during the operation of the winding, and further improving the performance of the induction electromagnetic pump 100 during operation.

[0086] Meanwhile, multiple vertical portions 111 are arranged at equal intervals, which can make the length of each horizontal portion 112 equal, so that the size of each annular winding 12 arranged on the horizontal portion 112 is equal, thereby improving the uniformity of the current distribution in each annular winding 12, and further improving the uniformity of the magnetic field generated by the induction electromagnetic pump 100, which is beneficial to improving the stability of the electromagnetic force driving the flow of the liquid metal, and thus improving the performance of the induction electromagnetic pump 100.

[0087] Moreover, since the size of each annular winding 12 is equal, it can also prevent the heat generated by a single annular winding 12 from being too large, thereby avoiding the occurrence of local overheating of the induction electromagnetic pump 100, which is conducive to extending the service life of the induction electromagnetic pump 100.

[0088] In addition, each annular winding 12 is sleeved on a horizontal portion 112, that is, one annular winding 12 is arranged on each "H"-shaped structure. Each annular winding 12 is located between two adjacent vertical portions 111. Both side surfaces of each annular winding 12 along the first preset direction 101 are flat, and the two side surfaces of each annular winding 12 are respectively attached to two adjacent vertical portions 111.

[0089] Through the above settings, the gap between each annular winding 12 and the horizontal portion 112 and the vertical portion can be reduced, thereby reducing the occupied space of the annular winding 12 on the mounting iron core 11, so as to improve the space utilization rate of the induction electromagnetic pump 100. At the same time, by arranging the annular winding 12 with flat side surfaces between two adjacent vertical portions 111, the gap between two adjacent vertical portions 111 can be filled to the maximum extent, thereby improving the slot fill factor of the induction electromagnetic pump 100 and improving the space utilization rate of the induction electromagnetic pump 100.

[0090] In this embodiment, both side surfaces of each annular winding 12 along the first preset direction 101 are flat. Each annular winding 12 is sleeved on a horizontal portion 112. Each annular winding 12 is located between two adjacent vertical portions 111. The two side surfaces of each annular winding 12 are respectively attached to two adjacent vertical portions 111. The first iron core 15 is located on the side of the first mounting iron core 11 away from the third mounting iron core 11. The second iron core 16 is located on the side of the second mounting iron core 11 away from the third mounting iron core 11.

[0091] The multiple flow channels 22 are respectively connected to the following positions: between two adjacent third mounting iron cores 11, between an adjacent third mounting iron core 11 and the first mounting iron core 11, between an adjacent third mounting iron core 11 and the second mounting iron core 11, between the first mounting iron core 11 and the first iron core 15, and between the second mounting iron core 11 and the second iron core 16. The multiple flow channels 22 are used for transporting liquid metal.

[0092] Through the above arrangement, multiple flow channels 22 are arranged on both sides of the mounting core 11, so that the magnetic force generated by the annular winding 12 can simultaneously drive the liquid metal in the multiple flow channels 22 to flow, thereby improving the working efficiency of the induction electromagnetic pump 100 and improving the performance of the induction electromagnetic pump 100.

[0093] In addition, the first iron core 15 and the second iron core 16 are provided to improve the heat dissipation efficiency of the induction electromagnetic pump 100. Therefore, the distance between the annular winding 12 and the flow channel 22 provided on the first mounting iron core 113 and the second mounting iron core can be shortened, thereby reducing the air gap between the annular winding 12 and the flow channel 22 on the first mounting iron core 113 and the second mounting iron core, so as to improve the power density of the induction electromagnetic pump 100 and further improve the performance of the induction electromagnetic pump 100.

[0094] The present application also provides an induction electromagnetic pump 100, which extends along a first preset direction 101 and includes a plurality of mounting cores 11 and a plurality of annular windings 12. The plurality of mounting cores 11 are arranged around a preset straight line extending along the first preset direction 101, and each mounting core 11 includes a plurality of vertical portions 111 and a plurality of transverse portions 112. The plurality of vertical portions 111 all extend along the circumference of the preset straight line, and the plurality of vertical portions 111 are arranged at equal intervals. The plurality of transverse portions 112 and the plurality of vertical portions 111 are integrally formed, each transverse portion 112 extends along the first preset direction 101, each transverse portion 112 is located between two adjacent vertical portions 111, and each transverse portion 112 connects the middle portions of two adjacent vertical portions 111, so that each transverse portion 112 forms an "H"-shaped structure with the two adjacent vertical portions 111.

[0095] Through the above-mentioned arrangement, the mounting core 11 is arranged as a plurality of connected "H"-shaped structures, so that the winding is wound around each section of the transverse portion 112 to form an annular winding 12, so that the annular winding 12 can be arranged on the mounting core 11, thereby shortening the length of the winding end to reduce the copper loss of the winding during operation, thereby improving the performance of the induction electromagnetic pump 100 during operation.

[0096] At the same time, the multiple vertical portions 111 are arranged at equal intervals, so that the length of each section of the transverse portion 112 is equal, so that each annular winding 12 arranged on the transverse portion 112 is equal in size, so as to improve the uniformity of the current distribution in each annular winding 12, thereby improving the uniformity of the magnetic field generated by the induction electromagnetic pump 100, so as to help improve the stability of the electromagnetic force driving the liquid metal to flow, thereby improving the performance of the induction electromagnetic pump 100. In addition, the equal size of each annular winding 12 can also avoid excessive heat generated by a single annular winding 12, thereby avoiding the occurrence of local overheating of the induction electromagnetic pump 100, so as to help extend the service life of the induction electromagnetic pump 100.

[0097] In addition, each annular winding 12 is sleeved on a transverse portion 112, that is, one annular winding 12 is provided on each "H"-shaped structure. Each annular winding 12 is located between two adjacent vertical portions 111. Both side surfaces of each annular winding 12 along the first preset direction 101 are flat, and the two side surfaces of each annular winding 12 are respectively attached to the two adjacent vertical portions 111.

[0098] Through the above settings, the gap between each annular winding 12 and the transverse portion 112 and the vertical portion can be reduced, thereby reducing the occupied space of the annular winding 12 on the mounting iron core 11, so as to improve the space utilization rate of the induction electromagnetic pump 100. At the same time, by arranging the annular winding 12 with flat side surfaces between two adjacent vertical portions 111, the gap between the two adjacent vertical portions 111 can be filled to the maximum extent, thereby improving the slot fill factor of the induction electromagnetic pump 100 and improving the space utilization rate of the induction electromagnetic pump 100.

[0099] Specifically, both side surfaces of each annular winding 12 along the first preset direction 101 are flat, each annular winding 12 is sleeved on a transverse portion 112, each annular winding 12 is located between two adjacent vertical portions 111, and the two side surfaces of each annular winding 12 are respectively attached to the two adjacent vertical portions 111.

[0100] Through the above settings, the gap between the annular winding 12 and the mounting iron core 11 can be reduced, so that the tightness when the annular winding 12 is attached to the groove wall 171 and the groove bottom 172 of the mounting groove 17 can be improved, so as to avoid a large gap when the annular winding 12 is arranged in the mounting groove 17, and further improve the slot fill factor of the mounting iron core 11, so as to improve the space utilization rate of the induction electromagnetic pump 100.

[0101] At the same time, when the slot fill factor of the mounting iron core 11 is increased, the number of turns of the annular winding 12 arranged in the unit space of the mounting iron core 11 can be increased, thereby increasing the magnetic field strength, and further increasing the power density of the induction electromagnetic pump 100, so as to improve the performance of the induction electromagnetic pump 100.

[0104] It should be noted that pole shoes 19 are installed on one side or both sides of the multiple flow channels 22 close to the installed iron core 11. Among them, the pole shoes 19 on the multiple flow channels 22 have the same effect as the pole shoes 19 on the first flow channel 13, and the pole shoes on the multiple flow channels 22 have the same effect as the pole shoes 19 on the second flow channel 14, which will not be elaborated here.
