Description

Technical Field

[0001] The present application relates to the field of electromagnetic pumps, and in particular to an induction electromagnetic pump. Background Art

[0002] An induction electromagnetic pump uses the principle of electromagnetic induction to drive the flow of conductive liquid metal. It is commonly used in liquid metal cooling systems in the nuclear industry and other applications requiring contactless movement of liquid metal. Existing induction electromagnetic pumps typically transport liquid metal by applying an alternating current to multiple windings mounted on an iron core, generating an alternating magnetic field. This alternating magnetic field induces eddy currents in the liquid metal. The interaction between the eddy currents and the magnetic field generates a Lorentz force, which propels the liquid metal in a specific direction within the pipe, achieving contactless transfer of the liquid metal.

[0003] However, existing induction electromagnetic pumps have long winding ends, creating a large gap between the ends and the core. This reduces the pump's slot fill rate and space utilization. Furthermore, the need for windings on both sides of the pipe to generate a magnetic field to drive the liquid metal flow reduces the pump's power density and, consequently, its performance.

[0004] Therefore, how to improve the performance and space utilization of the induction electromagnetic pump is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the specific implementation of the present application will be clearly and completely described below in conjunction with the drawings in the implementation of the present application.

[0029] It should be noted that the words "first", "second" and similar terms used in the specification and claims of this application do not indicate any order, quantity or importance, but are only used to distinguish different components.

[0030] As used in this specification and the appended claims, the singular forms "a," "an," "said," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0031] In order to clearly illustrate the technical solution of this application, the following is also defined: Figure 1 The front, rear, left, right, top and bottom shown represent the front, rear, left, right, top and bottom of the induction electromagnetic pump 100.

[0032] like Figure 1 and Figure 2As shown, the present application provides an induction electromagnetic pump 100, which extends along a first preset direction 101 and includes a mounting core 11, an annular winding 12, a first flow channel 13, a second flow channel 14, a first core 15, and a second core 16. The mounting core 11 is the main structure of the induction electromagnetic pump 100, used to support the annular winding 12, the first flow channel 13, the second flow channel 14, the first core 15, and the second core 16. The first flow channel 13 and the second flow channel 14 are respectively arranged on both sides of the mounting core 11 for conveying liquid metal. The annular winding 12 is arranged in the mounting core 11, and the first core 15 is connected to the first flow channel 13 for cooperating with the multiple annular windings 12 to generate a magnetic circuit. The second core 16 is connected to the second flow channel 14 and is also used to cooperating with the multiple annular windings 12 to generate a magnetic circuit.

[0033] When an alternating current passes through the toroidal winding 12, it generates a traveling wave magnetic field that extends along the distribution direction of the toroidal winding 12. After the traveling wave magnetic field is generated, the first iron core 15 and the second iron core 16 guide the traveling wave magnetic field 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 from the other end of the first iron core 15 and the second iron core 16 back to one end of the first iron core 15 and the second iron core 16, thereby forming a closed magnetic circuit. Furthermore, the traveling wave magnetic field induces eddy currents in the liquid metal in the first flow channel 13 and the second flow channel 14. The interaction between the eddy currents and the magnetic field generates a Lorentz force, which propels the liquid metal to flow along the extension direction of the first flow channel 13 or the second flow channel 14.

[0034] It should be noted that, in this application, the first preset direction 101 is Figure 1 The left and right directions of the induction electromagnetic pump 100.

[0035] Specifically, the mounting core 11 includes a plurality of vertical portions 111 and a plurality of transverse portions 112. The plurality of vertical portions 111 extend along the second preset direction 102, and the plurality of vertical portions 111 are arranged at equal intervals. The second preset direction 102 is perpendicular to the first preset direction 101. In this application, the second preset direction 102 is Figure 1 The up and down directions of the induction electromagnetic pump 100 are shown.

[0036] Multiple transverse portions 112 and multiple 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 parts of two adjacent vertical portions 111, so that each transverse portion 112 and the two adjacent vertical portions 111 form an "H"-shaped structure.

[0037] Through the above-mentioned setting, the mounting core 11 is set to a plurality of connected "H"-shaped structures, so that the winding is wound on each transverse portion 112 to form a ring winding 12, so that the ring winding 12 can be arranged on the mounting core 11, and then the length of the winding end is shortened to reduce the copper loss of the winding during operation, thereby improving the performance of the induction electromagnetic pump 100 during operation.

[0038] At the same time, the multiple vertical portions 111 are arranged at equal intervals, so that the length of each transverse portion 112 is equal, and thus the size of each annular winding 12 arranged on the transverse portion 112 is equal, so as to improve the uniformity of the current distribution in each annular winding 12, and further improve the uniformity of the magnetic field generated by the induction electromagnetic pump 100, which is conducive to improving the stability of the electromagnetic force driving the flow of liquid metal, thereby improving the performance of the induction electromagnetic pump 100.

[0039] Furthermore, each annular winding 12 is of equal size, which can prevent excessive heat generated by a single annular winding 12 , thereby preventing local overheating of the induction electromagnetic pump 100 , thereby extending the service life of the induction electromagnetic pump 100 .

[0040] Furthermore, each annular winding 12 is sleeved on a transverse portion 112, i.e., each H-shaped structure is provided with an annular winding 12. Each annular winding 12 is located between two adjacent vertical portions 111, and both side surfaces of each annular winding 12 along the first predetermined direction 101 are planar, and both side surfaces of each annular winding 12 are in contact with the two adjacent vertical portions 111.

[0041] Through this arrangement, the gaps between each annular winding 12 and the transverse portion 112 and the vertical portion can be reduced, thereby reducing the space occupied by the annular winding 12 on the mounting core 11, thereby improving the space utilization of the induction electromagnetic pump 100. Furthermore, by disposing an annular winding 12 with flat side surfaces between two adjacent vertical portions 111, the gap between the adjacent vertical portions 111 can be filled to the maximum extent possible, thereby improving the slot fill rate of the induction electromagnetic pump 100 and improving the space utilization of the induction electromagnetic pump 100.

[0042] In the present application, the first flow channel 13 is used to transport liquid metal and is connected to the plurality of vertical portions 111. The second flow channel 14 is used to transport liquid metal and is connected to the plurality of vertical portions 111. The second flow channel 14 and the first flow channel 13 are located on both sides of the plurality of vertical portions 111 along the second preset direction 102.

[0043] Specifically, along the vertical 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 disposed on either side of the mounting core 11, so that the electromagnetic thrust generated by the annular winding 12 can simultaneously drive the flow of liquid metal within the first flow channel 13 and the second flow channel 14, thereby improving the operating efficiency of the induction electromagnetic pump 100 and enhancing the performance of the induction electromagnetic pump 100.

[0044] In this embodiment, the first core 15 is located on a side of the first flow channel 13 away from the vertical portion 111 and connected to the first flow channel 13. The second core 16 is located on a side of the second flow channel 14 away from the vertical portion 111 and connected to the second flow channel 14.

[0045] Through the above-mentioned setting, the first iron core 15 and the second iron core 16 are set. 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.

[0046] 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.

[0047]

[0048] 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 output pressure of 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. On the basis of increasing the output pressure, it can also increase the flow rate of liquid metal per unit time, thereby improving the performance of the induction electromagnetic pump 100.

[0049] As an embodiment, each transverse portion 112 and two adjacent vertical portions 111 are formed with two mounting slots 17, and the two mounting slots 17 are located on either side of the transverse portion 112 along the second predetermined direction 102. Each annular winding 12 includes two straight segments 121 and two curved segments 122, wherein one curved segment 122 is connected to one end of the two straight segments 121, and the other curved segment 122 is connected to the other end of the two straight segments 121. The two straight segments 121 are respectively located in the two corresponding mounting slots 17.

[0050] Through the above arrangement, each annular winding 12 can be wound between the corresponding two mounting slots 17. In the present application, each annular winding 12 is arranged in a runway shape, which can increase the number of turns of the annular winding 12, thereby reducing the current in the annular winding 12, and further reducing the copper loss of the annular winding 12, thereby reducing the loss of the induction electromagnetic pump 100, thereby improving 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 conducive to promoting the efficiency of the liquid metal in the first flow channel 13 and the second flow channel 14, thereby improving the performance of the induction electromagnetic pump 100.

[0051] It should be noted that, in the present application, there is no limitation on the structure of the annular winding 12 , which only needs to improve the performance of the induction electromagnetic pump 100 .

[0052] As an embodiment, each straight segment 121 is aligned with the groove wall 171 and groove bottom 172 of the corresponding mounting groove 17. This arrangement allows the annular winding 12 to be in direct contact with the mounting groove 17, thereby facilitating the transfer of heat generated internally by the annular winding 12 to the outside during operation, thereby preventing overheating within the induction electromagnetic pump 100 and extending the service life of the annular winding 12, thereby extending the service life of the induction electromagnetic pump 100. Furthermore, the alignment of each straight segment 121 with the groove wall 171 and groove bottom 172 of the corresponding mounting groove 17 can also reduce the gap between the annular winding 12 and the mounting groove 17, thereby facilitating increasing the groove fill rate of the induction electromagnetic pump 100 and thereby improving the performance of the induction electromagnetic pump 100.

[0053] As an embodiment, both side surfaces of the two straight segments 121 along the first preset direction 101 are planes, and both side surfaces of the two curved segments 122 along the first preset direction 101 are planes, and the side surfaces on the same side of the two straight segments 121 and the two curved segments 122 are on the same plane.

[0054] Through the above-mentioned arrangement, the contact surface between the straight section 121 and the mounting groove 17 can be made flat, and the contact surface between the curved section 122 and the mounting groove 17 can be made flat. At the same time, the contact surface between the straight section 121 and the mounting groove 17 and the contact surface between the curved section 122 and the mounting groove 17 are all on the same plane, thereby improving the degree of close contact between the annular winding 12 and the groove wall 171 and the groove bottom 172 of the mounting groove 17, thereby avoiding leaving a large gap when the annular winding 12 is set in the mounting groove 17, thereby improving the slot fill rate of the mounting core 11, and improving the space utilization rate of the induction electromagnetic pump 100.

[0055] At the same time, the slot filling rate of the mounting core 11 is improved, which can increase the number of turns of the annular winding 12 set in the unit space of the mounting 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.

[0056] As an embodiment, the notches 173 of the mounting grooves 17 are all away from the transverse portion 112. In the present application, the notches 173 are located at the connection between the vertical portion 111 and the first flow channel 13 or the second flow channel 14.

[0057] Through the above arrangement, sufficient space can be provided for installing the iron core 11, so that a more number of turns of the annular winding 12 can be arranged in the installation groove 17, so that the annular winding 12 can generate a stronger magnetic field during operation, thereby increasing the power density of the induction electromagnetic pump 100 and improving the performance of the induction electromagnetic pump 100.

[0058] As an embodiment, the maximum span of the plurality of annular windings 12 along the first preset direction 101 is the winding span L1, the maximum length of the mounting core 11 along the first preset direction 101 is the core length L2, and the ratio of the winding span to the core length is greater than or equal to 0.7 and less than 1. Specifically, the ratio of the winding span to the 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 core length is greater than or equal to 0.8 and less than or equal to 0.9. In the present application, equal spacing is provided between adjacent annular windings 12, and the extension direction of the plurality of annular windings 12 and the extension direction of the mounting core 11 both extend along the first preset direction 101, that is, Figure 1 The left and right directions of the induction electromagnetic pump 100.

[0059] Through the above-mentioned arrangement, it is possible to avoid the ratio of the winding span to the length of the mounting core 11 being too small, so as to increase the setting 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 core 11 in the second preset direction 102, and the first flow channel 13 and the second flow channel 14 both 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, so as to facilitate 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.

[0060] At the same time, when the iron core 11 is installed in the first preset direction 101, the annular winding 12 can fill the installation slot 17, thereby improving the slot fill rate of the induction electromagnetic pump 100 and thus improving the space utilization of the induction electromagnetic pump 100. In addition, the improved slot fill rate of the installation iron core 11 can increase the number of turns of the annular winding 12 set per unit space of the installation iron core 11, thereby increasing the magnetic field strength, and further increasing the power density of the induction electromagnetic pump 100, thereby improving the performance of the induction electromagnetic pump 100.

[0061] As an embodiment, the induction electromagnetic pump 100 further includes a plurality of short-circuit bars 18, which are respectively located at the following positions: on both sides of the first flow channel 13 along the third preset direction 103, and on both sides of the second flow channel 14 along the third preset direction 103, wherein 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 Figure 1 The front-to-back direction of the induction electromagnetic pump 100 is shown, and in the present application, the short-circuit bar 18 can be a highly conductive metal member.

[0062] For example, in the present application, the short-circuit bar 18 can be made of copper. The copper short-circuit bar 18 can enhance the electromagnetic force exerted by the toroidal winding 12 on the first flow channel 13 or the second flow channel 14, thereby improving the stability and efficiency of liquid metal transmission in the first flow channel 13 or the second flow channel 14, thereby improving the performance of the induction electromagnetic pump 100.

[0063] It should be noted that the present application does not impose any restrictions on the material of the short-circuit bar 18 , as long as it has high conductivity.

[0064] Through the above arrangement, short-circuit bar 18 can increase the electrical conductivity of first flow channel 13 and second flow channel 14, thereby improving the stability of the electromagnetic force acting within first flow channel 13 and second flow channel 14. This prevents the liquid metal from irregularly flowing in a circular direction within first flow channel 13 or second flow channel 14 after being subjected to the electromagnetic force. This allows the liquid metal flow path to flow sequentially along multiple parallel rectangular directions, thereby improving the stability of liquid metal transmission and the performance of induction electromagnetic pump 100. Furthermore, in the present application, the connection method between short-circuit bar 18 and first flow channel 13, and between short-circuit bar 18 and second flow channel 14, can be welding or adhesive bonding.

[0065] For example, the adhesive may be an epoxy resin adhesive. Epoxy resin adhesive has strong connection strength and hardness, which can improve the stability of the connection between the shorting bar 18 and the first flow channel 13 or the second flow channel 14 .

[0066] It should be noted that the present application does not impose any restrictions on the installation method of the shorting bar 18 and the material of the adhesive. It only needs to ensure the connection strength between the shorting bar 18 and the first flow channel 13 or the second flow channel 14 .

[0067] As an embodiment, the first flow channel 13 and the second flow channel 14 both extend along the first preset direction 101, the opening of the first flow channel 13 is located on both sides of the first flow channel 13 along the first preset direction 101, and the opening of the second flow channel 14 is located on both sides of the first flow channel 13 along the first preset direction 101.

[0068] Through the above-mentioned setting, the setting direction and opening direction of the first flow channel 13 and the second flow channel 14 can be adapted to the setting direction of the annular winding 12, so that the direction of the electromagnetic force generated by the annular winding 12 is the same as the setting direction and opening direction of the first flow channel 13 and the second flow channel 14, so as to reduce the resistance generated by the liquid metal flowing in the first flow channel 13 and the second flow channel 14 when the electromagnetic force acts on it, thereby improving the transmission efficiency of the liquid metal in the first flow channel 13 and the second flow channel 14, thereby improving the performance of the induction electromagnetic pump 100.

[0069] like Figure 3 and Figure 4 As shown, as an embodiment, the present application provides a magnetic field distribution diagram of an induction electromagnetic pump 100 and an electromagnetic pump in the prior art. Figure 3 is the magnetic field distribution diagram of the electromagnetic pump in the prior art, Figure 4 This is the magnetic field distribution diagram of the induction electromagnetic pump 100 of this application. Figure 3 and Figure 4By comparison, the magnetic field of conventional electromagnetic pumps is primarily concentrated in the middle of the core, resulting in a stronger magnetic field in the middle and weaker fields on either side. This results in unstable electromagnetic forces acting on the liquid metal, which in turn affects the stability of liquid metal transmission. In contrast, the magnetic field strength distribution of the induction electromagnetic pump 100 is more uniform across the core 11, ensuring a more uniform electromagnetic force on the liquid metal during transmission, thereby improving the stability of liquid metal transmission.

[0070] like Figure 5 and Figure 6 As shown, as an implementation, the induction electromagnetic pump 100 includes a pole shoe 19, which is made of a silicon steel sheet 191, or a plurality of stacked silicon steel sheets 191. The pole shoe 19 is used to enhance the linearity of the traveling wave magnetic field, thereby improving the uniformity of the traveling wave magnetic field, thereby improving the stability of the liquid metal transmission under the traveling wave magnetic field, and further improving the operational stability of the induction electromagnetic pump 100.

[0071] It should be noted that when the pole shoe 19 is composed of a plurality of stacked silicon steel sheets 191, the two adjacent silicon steel sheets 191 are bonded by insulating glue, so that the two adjacent silicon steel sheets 191 are electrically insulated to prevent eddy currents from flowing between the two adjacent silicon steel sheets 191, thereby shortening the path of eddy current flow and reducing the eddy current loss of the induction electromagnetic pump 100.

[0072] It should be noted that by stacking multiple silicon steel sheets 191, the thickness of the pole shoe 19 can meet the requirements for magnetic conductivity, thereby improving the operational stability of the induction electromagnetic pump 100. At the same time, while meeting the radial thickness of the pole shoe 19, the radial thickness of a single silicon steel sheet 191 can be reduced, thereby reducing the induced electromotive force accumulated in a single silicon steel sheet 191, thereby reducing the eddy current value of the pole shoe 19 during magnetic conductivity, and thus reducing the eddy current loss of the induction electromagnetic pump 100.

[0073] Exemplarily, the pole shoe 19 is mounted on a side of the first flow channel 13 close to the mounting core 11, and / or, the pole shoe 19 is mounted on a side of the second flow channel 14 close to the mounting core 11. Specifically, the pole shoe 19 is located between the first flow channel 13 and the plurality of vertical portions 111, and / or, the pole shoe 19 is located between the second flow channel 14 and the plurality of vertical portions 111.

[0074] 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, thereby avoiding short circuit between the outer walls of the first flow channel 13 and the second flow channel 14 and ensuring the structural strength of the pole shoe 19.

[0075] 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 wave magnetic field acting on the first flow channel 13 and / or the second flow channel 14, thereby improving the stability of the liquid metal flowing in the first flow channel 13 and / or the second flow channel 14 when the liquid metal is acted upon by the traveling wave magnetic field, thereby improving the stability of the induction electromagnetic pump 100 in transmitting the liquid metal.

[0076] In this embodiment, two adjacent vertical portions 111 correspond to one pole shoe 19, and the pole shoe 19 is formed by two silicon steel sheets 191 distributed along the first preset direction 101, and a gap exists between the two silicon steel sheets 191 along the first preset direction 101, thereby forming a semi-open slot 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 composed of multiple silicon steel sheets 191 stacked together, and a gap exists between the two groups of silicon steel sheets 191 along the first preset direction 101, thereby forming a semi-open slot between the pole shoe 19 and the two adjacent vertical portions 111.

[0077] Through the above arrangement, a gap exists between two adjacent groups of silicon steel sheets 191 in the first predetermined direction 101, thereby shortening the path length of eddy current flow within each group of silicon steel sheets 191, thereby reducing eddy current losses within the pole shoe 19 and, in turn, reducing eddy current losses of the induction electromagnetic pump 100. Furthermore, the arrangement of the pole shoe 19 transforms the open slot between the mounting core 11 and the first flow channel 13 or the second flow channel 14 into 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.

[0078] like Figure 2 and Figure 7 As shown, as an optional implementation method, 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. The gap can block the eddy current from flowing between the two adjacent pole shoes 19, thereby shortening the path length of the eddy current flow, so as to reduce the eddy current loss in the pole shoe 19, thereby reducing the loss during operation of the induction electromagnetic pump 100.

[0079] 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 silicon steel sheets 191 can be divided into multiple first silicon steel sheets 192, and there is a gap between each of the first silicon steel sheets 192. The multiple first silicon steel sheets 192 can be distributed along the first preset direction 101, and the multiple first silicon steel sheets 192 can also be distributed along the third preset direction 103, which is not limited here.

[0080] like Figure 2 and Figure 6As shown, as an implementation, each vertical portion 111 is provided with a plurality of first cooling holes 1111 extending through the vertical portion 111 along the third predetermined direction 103. In conventional electromagnetic pumps, the core teeth are surrounded by the windings, which obstructs the core teeth. This prevents the core from having cooling holes, preventing effective heat dissipation of the windings during operation, and thus affecting normal operation of the windings.

[0081] Through the above-described arrangement, since the annular winding 12 in the present application is wound around the transverse portion 112 (i.e., the yoke portion on which the core 11 is mounted) between two adjacent vertical portions 111, the annular winding 12 can be prevented from completely enveloping the vertical portion 111 (i.e., the tooth portion on which the core 11 is mounted). This prevents the first cooling holes 1111 provided along the third preset direction 103 on each vertical portion 111 from being blocked by the annular winding 12. Consequently, heat can be dissipated from the annular winding 12 via the first cooling holes 1111, thereby preventing overheating of the induction electromagnetic pump 100 during operation and improving the safety of the induction electromagnetic pump 100 during operation. Furthermore, providing multiple first cooling holes 1111 on each vertical portion 111 can improve the efficiency of heat transfer per unit area, thereby improving the heat dissipation efficiency of the annular winding from the first cooling holes 1111, further improving the safety of the induction electromagnetic pump 100 during operation.

[0082] As an implementation method, each vertical portion 111 is provided with a plurality of second cooling holes 1112 that pass through the vertical portion 111 along the first preset direction 101, and each transverse portion 112 is provided with a plurality of third cooling holes (not shown) that pass through the transverse portion 112 along the first preset direction 101. The second cooling holes 1112 and the third cooling holes are arranged overlappingly along the first preset direction 101, so that the second cooling holes 1112 and the third cooling holes are connected to form a cooling through hole that passes through the mounting core 11 along the first preset direction 101. The yoke of the core of the existing electromagnetic pump is arranged on one side of the winding, so that the winding cannot be fully cooled. However, the yoke of the mounting core 11 (i.e., the transverse portion 112) of the present application is surrounded by the annular winding 12, so that the annular winding 12 can be fully cooled.

[0083] Through the above-mentioned arrangement, a second cooling hole 1112 is provided on the vertical portion 111 of the induction electromagnetic pump 100, so that the heat generated by the annular winding 12 between two adjacent vertical portions 111 can be transmitted along the first preset direction 101, and the second cooling hole 1112 and the third cooling hole overlap in the first preset direction 101, so that the heat generated by the annular winding 12 is transmitted to the external environment after passing through the second cooling hole 1112 and the third cooling hole, thereby avoiding the heat generated by the annular winding 12 during operation from accumulating in the induction electromagnetic pump 100, avoiding the induction electromagnetic pump 100 from being lost due to overheating, and thereby improving the service life of the induction electromagnetic pump 100.

[0084] At the same time, a plurality of second cooling holes 1112 are provided on each vertical portion 111 and a plurality of third cooling holes are provided on the transverse portion 112, which can improve the heat dissipation efficiency per unit area of the induction electromagnetic pump, thereby improving the temperature stability of the induction electromagnetic pump 100 during operation, and improving the safety of the induction electromagnetic pump 100 during operation.

[0085] In addition, the second cooling hole 1112 and the third cooling hole are arranged overlappingly along the first preset direction 101, and the third cooling hole passes through the transverse portion 112, so that the second cooling holes 1112 on the two adjacent vertical portions 111 can be connected through the third cooling hole to form a cooling through hole that passes through the installation iron core 11 along the first preset direction 101. The cooling through hole can transfer heat to the outside world, thereby avoiding the problem of local overtemperature when some annular windings 12 are unable to transfer excess heat to the outside world when the induction electromagnetic pump 100 is operating, further improving the safety of the induction electromagnetic pump 100 during operation.

[0086] like Figure 2 and Figure 8 As shown, the present application provides an induction electromagnetic pump 100, which extends along a first preset direction 101 and includes a plurality of mounting cores 11, a plurality of annular windings 12, a first core 15, a second core 16, and a plurality of flow channels 22. The plurality of mounting cores 11 are distributed along a second preset direction 102, two of which are defined as a first mounting core 113 and a second mounting core 114, and the remaining mounting cores 11 are defined as third mounting cores 115. The plurality of third mounting cores 115 are located between the first mounting core 113 and the second mounting core 114 along the second preset direction 102.

[0087] Each mounting core 11 includes a plurality of vertical portions 111 and a plurality of transverse portions 112. The plurality of vertical portions 111 extend along a second predetermined direction 102, and the plurality of vertical portions 111 are arranged at equal intervals. The second predetermined direction 102 is perpendicular to the first predetermined 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 predetermined direction 101, and each transverse portion 112 is located between two adjacent vertical portions 111. Each transverse portion 112 connects the middle portions of two adjacent vertical portions 111, so that each transverse portion 112 and the two adjacent vertical portions 111 form an "H"-shaped structure.

[0088] Through the above-mentioned setting, the mounting core 11 is set to a plurality of connected "H"-shaped structures, so that the winding is wound on each transverse portion 112 to form a ring winding 12, so that the ring winding 12 can be arranged on the mounting core 11, and then the length of the winding end is shortened to reduce the copper loss of the winding during operation, thereby improving the performance of the induction electromagnetic pump 100 during operation.

[0089] At the same time, the multiple vertical portions 111 are arranged at equal intervals, so that the length of each transverse portion 112 is equal, and thus the size of each annular winding 12 arranged on the transverse portion 112 is equal, so as to improve the uniformity of the current distribution in each annular winding 12, and further improve the uniformity of the magnetic field generated by the induction electromagnetic pump 100, which is conducive to improving the stability of the electromagnetic force driving the flow of liquid metal, thereby improving the performance of the induction electromagnetic pump 100.

[0090] Furthermore, each annular winding 12 is of equal size, which can prevent excessive heat generated by a single annular winding 12 , thereby preventing local overheating of the induction electromagnetic pump 100 , thereby extending the service life of the induction electromagnetic pump 100 .

[0091] Furthermore, each annular winding 12 is sleeved on a transverse portion 112, i.e., each H-shaped structure is provided with an annular winding 12. Each annular winding 12 is located between two adjacent vertical portions 111, and both side surfaces of each annular winding 12 along the first predetermined direction 101 are planar, and both side surfaces of each annular winding 12 are in contact with the two adjacent vertical portions 111.

[0092] Through this arrangement, the gaps between each annular winding 12 and the transverse portion 112 and the vertical portion can be reduced, thereby reducing the space occupied by the annular winding 12 on the mounting core 11, thereby improving the space utilization of the induction electromagnetic pump 100. Furthermore, by disposing an annular winding 12 with flat side surfaces between two adjacent vertical portions 111, the gap between the adjacent vertical portions 111 can be filled to the maximum extent possible, thereby improving the slot fill rate of the induction electromagnetic pump 100 and improving the space utilization of the induction electromagnetic pump 100.

[0093] In this embodiment, both side surfaces of each annular winding 12 along the first predetermined direction 101 are planar. Each annular winding 12 is sleeved on a transverse portion 112. Each annular winding 12 is located between two adjacent vertical portions 111, and both side surfaces of each annular winding 12 are respectively aligned with the two adjacent vertical portions 111. The first core 15 is located on the side of the first mounting core 11 facing away from the third mounting core 11. The second core 16 is located on the side of the second mounting core 11 facing away from the third mounting core 11.

[0094] Multiple flow channels 22 are respectively connected to the following positions: between two adjacent third mounting cores 11, between adjacent third mounting cores 11 and first mounting cores 11, between adjacent third mounting cores 11 and second mounting cores 11, between the first mounting core 11 and the first core 15, and between the second mounting core 11 and the second core 16. Multiple flow channels 22 are used to transport liquid metal.

[0095] 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.

[0096] In addition, providing the first iron core 15 and the second iron core 16 can 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.

[0097] 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 circumferentially along 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 the two adjacent vertical portions 111, so that each transverse portion 112 forms an "H"-shaped structure with the two adjacent vertical portions 111.

[0098] Through the above-mentioned setting, the mounting core 11 is set to a plurality of connected "H"-shaped structures, so that the winding is wound on each transverse portion 112 to form a ring winding 12, so that the ring 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.

[0099] At the same time, the equal spacing of the multiple vertical portions 111 ensures that the lengths of each transverse portion 112 are equal, thereby ensuring that each annular winding 12 disposed on the transverse portion 112 is of equal size. This improves the uniformity of current distribution within each annular winding 12, thereby improving the uniformity of the magnetic field generated by the induction electromagnetic pump 100, thereby facilitating the stability of the electromagnetic force driving the flow of liquid metal, thereby improving the performance of the induction electromagnetic pump 100. Furthermore, the equal size of each annular winding 12 prevents excessive heat generation by a single annular winding 12, thereby preventing localized overheating of the induction electromagnetic pump 100 and extending the service life of the induction electromagnetic pump 100.

[0100] Furthermore, each annular winding 12 is sleeved on a transverse portion 112, i.e., each H-shaped structure is provided with an annular winding 12. Each annular winding 12 is located between two adjacent vertical portions 111, and both side surfaces of each annular winding 12 along the first predetermined direction 101 are planar, and both side surfaces of each annular winding 12 are in contact with the two adjacent vertical portions 111.

[0101] Through this arrangement, the gaps between each annular winding 12 and the transverse portion 112 and the vertical portion can be reduced, thereby reducing the space occupied by the annular winding 12 on the mounting core 11, thereby improving the space utilization of the induction electromagnetic pump 100. Furthermore, by disposing an annular winding 12 with flat side surfaces between two adjacent vertical portions 111, the gap between the adjacent vertical portions 111 can be filled to the maximum extent possible, thereby improving the slot fill rate of the induction electromagnetic pump 100 and improving the space utilization of the induction electromagnetic pump 100.

[0102] Specifically, both side surfaces of each annular winding 12 along the first preset direction 101 are planes, each annular winding 12 is sleeved on a horizontal portion 112, each annular winding 12 is located between two adjacent vertical portions 111, and both side surfaces of each annular winding 12 are respectively in contact with the two adjacent vertical portions 111.

[0103] Through the above-mentioned arrangement, the gap between the annular winding 12 and the mounting core 11 can be reduced, thereby improving the degree of close contact between the annular winding 12 and the slot wall 171 and the slot bottom 172 of the mounting slot 17, so as to avoid leaving a large gap when the annular winding 12 is arranged in the mounting slot 17, thereby improving the slot fill rate of the mounting core 11 and improving the space utilization of the induction electromagnetic pump 100.

[0104] At the same time, the slot filling rate of the mounting core 11 is improved, which can increase the number of turns of the annular winding 12 set in the unit space of the mounting 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.

[0105] More specifically, the plurality of flow channels 22 are located between two adjacent mounting cores 11, and the plurality of flow channels 22 are respectively connected to the two adjacent mounting cores 11. The plurality of flow channels 22 are used to transport liquid metal.

[0106] Through the above-mentioned arrangement, a plurality of mounting cores 11 can be interconnected and formed into a ring, so that a flow channel 22 is provided between two adjacent mounting cores 11. This can improve the effect of the annular winding 12 on the liquid metal while reducing the occupied space of the induction electromagnetic pump 100, thereby improving the performance of the induction electromagnetic pump 100.

[0107] It should be noted that pole shoes 19 are installed on one or both sides of the multiple flow channels 22 close to the mounting core 11. 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 repeated here.

[0108] It should be understood that those skilled in the art can make improvements or changes based on the above description, and all such improvements and changes should fall within the scope of protection of the claims appended to this application.
