As shown in fig. 1 and 2, the present application provides an induction type electromagnetic pump 100, which is a planar induction type electromagnetic pump having a pipe diameter of 10mm or less, a flow rate of 20L/h or less, and an output power of 3W or less. The induction type electromagnetic pump 100 of the present application can be used as a laboratory pump or the like for driving the directional flow of liquid metal.

Specifically, the induction electromagnetic pump 100 includes a base 11, a cover plate 12, a core assembly 13, windings 14, and a flow passage 15. Wherein, the base 11 and the cover 12 are connected and form an accommodating space for accommodating the iron core assembly 13, the winding 14 and the runner 15, so that the base 11 and the cover 12 become a basic frame for supporting the iron core assembly 13, the winding 14 and the runner 15 after being connected, thereby facilitating the assembly and the normal operation of the induction electromagnetic pump 100. The winding 14 is used for conveying current, and the winding 14 is wound on the iron core component 13, so that the iron core component 13 can generate a magnetic field through the current in the winding 14, and electromagnetic induction is realized. The flow channel 15 is used as a flow channel for the liquid metal, and in the present application, the flow channel 15 having a rectangular cross section is exemplified.

In the application, after the winding 14 is electrified, the magnetic field generated by the iron core component 13 acts with the liquid metal in the runner 15 to generate induced current, and the liquid metal in the runner 15 becomes a current carrying conductor, so that the liquid metal acts with the magnetic field to generate electromagnetic force, and the liquid metal is driven to flow directionally.

It should also be understood that the term "and/or" as used herein refers to and encompasses any or all possible combinations of one or more of the associated listed items.

As shown in fig. 1 and 2, as one implementation, the core assembly 13 includes a first core 131 and a second core 132, and the first core 131 and the second core 132 are distributed in the left-right direction of the induction electromagnetic pump 100. The winding 14 is wound on the first core 131 and the second core 132, so that the first core 131 and the second core 132 can generate a magnetic field by a current in the winding 14, thereby achieving electromagnetic induction.

Specifically, in the up-down direction of the induction electromagnetic pump 100, the first iron core 131 and the second iron core 132 are each at least partially located between the base 11 and the cover 12, and the first iron core 131 and the second iron core 132 are each abutted to the upper side of the base 11 and the lower side of the cover 12. Since the first core 131 and the second core 132 are attracted to each other, if only the first core 131 and the second core 132 are fixed to the base 11, the base 11 is bent and deformed due to the force generated by the attraction of the first core 131 and the second core 132, that is, the left and right sides of the base 11 are bent upward. Thus, by the arrangement of the cover plate 12 of the present application, the first core 131 and the second core 132 can be connected by the cover plate 12 and the base 11. Meanwhile, the first and second cores 131 and 132 are abutted to the upper side of the base 11 and the lower side of the cover 12 by both the first and second cores 131 and 132 to jointly fix the first and second cores 131 and 132 by the cover 12 and the base 11, so that the bending stress of the base 11, which is originally caused by the first and second cores 131 and 132, becomes the bending stress generated by the base 11 and the cover 12 at the same time. The bending stress generated by the base 11 and the cover 12 can be counteracted by the pressing force of the base 11 and the cover 12 to the first iron core 131 and the second iron core 132, so that the bending stress of the whole induction type electromagnetic pump 100 is changed into the compressive stress, the structural stress of the induction type electromagnetic pump 100 is changed, the integral rigidity of the induction type electromagnetic pump 100 is improved, and the service life of the induction type electromagnetic pump 100 is prolonged.

As shown in fig. 2 and 3, more specifically, the upper side of the base 11 is provided with a first groove 111, the first groove 111 is at least partially protruded upward to form a first partition 112, and the height of the first partition 112 along the up-down direction of the induction type electromagnetic pump 100 is greater than the depth of the first groove 111 along the up-down direction of the induction type electromagnetic pump 100, so that the first iron core 131 and the second iron core 132 are respectively abutted to the left and right sides of the first partition 112, and further the first partition 112 can position the first iron core 131 and the second iron core 132, so that the first iron core 131 and the second iron core 132 can be assembled.

The second groove body 121 is formed at the lower side of the cover plate 12, the second groove body 121 is at least partially protruded downwards to form the second separation part 122, the height of the second separation part 122 along the upper and lower direction of the induction type electromagnetic pump 100 is larger than the depth of the second groove body 121 along the upper and lower direction of the induction type electromagnetic pump 100, and accordingly the first iron core 131 and the second iron core 132 are respectively abutted to the left side and the right side of the second separation part 122, and the second separation part 122 can position the first iron core 131 and the second iron core 132 so as to facilitate assembly of the first iron core 131 and the second iron core 132.

After the winding 14 is wound on the first iron core 131 and the second iron core 132, the ends of the upper and lower ends of the winding 14 at least partially protrude from the first iron core 131 and the second iron core 132, that is, the height of the winding 14 along the up-down direction of the induction type electromagnetic pump 100 is greater than the height of the first iron core 131 along the up-down direction of the induction type electromagnetic pump 100, or the height of the winding 14 along the up-down direction of the induction type electromagnetic pump 100 is greater than the height of the second iron core 132 along the up-down direction of the induction type electromagnetic pump 100. When the base 11 and the cover 12 are connected, in order to avoid the situation that the first iron core 131 and the second iron core 132 cannot be abutted against the base 11 and/or the cover 12 due to the existence of the winding 14, the winding 14 is at least partially located in the first slot body 111 and the second slot body 121, so that an arrangement space can be provided for the winding 14 through the first slot body 111 and the second slot body 121, the first iron core 131 and the second iron core 132 are both abutted against the base 11 and/or the cover 12, so that the base 11 and the cover 12 generate pressing force on the first iron core 131 and the second iron core 132, and further, the bending stress of the whole induction type electromagnetic pump 100 is changed into compressive stress, so that the structural stress of the induction type electromagnetic pump 100 is changed, and the whole rigidity and the service life of the induction type electromagnetic pump 100 are improved. In addition, through the above arrangement, the positions of the windings 14 can be defined by the first slot body 111 and the second slot body 121, so that the positioning of the first iron core 131 and the second iron core 132 can be further realized through the windings 14, and the normal operation of the induction electromagnetic pump 100 is facilitated.

In the present embodiment, the flow passage 15 is located between the first partition 112 and the second partition 122 in the up-down direction of the induction electromagnetic pump 100, the flow passage 15 is respectively abutted to the upper side of the first partition 112 and the lower side of the second partition 122, and the flow passage 15 is also respectively connected to the upper side of the first partition 112 and the lower side of the second partition 122; along the left-right direction of the induction electromagnetic pump 100, the runner 15 is located between the first iron core 131 and the second iron core 132, the first iron core 131 and the second iron core 132 are respectively abutted to the left and right sides of the runner 15, and the first iron core 131 and the second iron core 132 are also respectively connected to the left and right sides of the runner 15. Because the flow channel 15 of the induction electromagnetic pump 100 of the present application has a smaller pipe diameter, when fluid flows through the flow channel 15 with a small cross section, according to the bernoulli principle, the pipe walls at the two sides of the flow channel 15 will adsorb to the middle, thereby causing the flow channel 15 to be blocked. Through the arrangement of the application, namely the first partition part 112, the second partition part 122, the first iron core 131 and the second iron core 132 are respectively connected with the four sides of the flow channel 15, the side wall 1251 of the flow channel 15 is prevented from being adsorbed to the middle, the influence of Bernoulli principle on the flow channel 15 is further effectively reduced, the running stability and the overall structural rigidity of the induction electromagnetic pump 100 are improved, and the service life of the induction electromagnetic pump 100 is prolonged.

By way of example, defining a horizontal plane 101 perpendicular to the vertical direction of the induction type electromagnetic pump 100, the induction type electromagnetic pump 100 of the present application can increase the overall rigidity of the induction type electromagnetic pump 100 by the structural arrangement of the base 11, the cover 12, the first iron core 131 and the second iron core 132, so that the induction type electromagnetic pump 100 can bend any portion of the base 11, the cover 12, the first iron core 131 and/or the second iron core 132 when the induction type electromagnetic pump 100 is continuously operated for thirty days, the angle between the upper surface of the base 11, the cover 12, the first iron core 131 and/or the second iron core 132 after bending and the horizontal plane 101 is less than 1 °, and/or the angle between the lower surface of the base 11, the cover 12, the first iron core 131 and/or the second iron core 132 after bending and the horizontal plane 101 is less than 1 °.

As shown in fig. 4, as another implementation, the induction electromagnetic pump 100 includes a first partition 112 in the first tank 111 and a second partition 122 in the second tank 121, the first partition 112 being connected to the bottom of the first tank 111 and dividing the first tank 111 into two first partition grooves, the second partition 122 being connected to the bottom of the second tank 121 and dividing the second tank 121 into two second partition grooves. That is, in the present embodiment, the first partition 112 and the first tank 111 are separate two members, and the first partition 112 and the first tank 111 are connected by glue; the second partition 122 and the second groove 121 are separate two components, and the second partition 122 and the second groove 121 are connected by glue. Because the induction electromagnetic pump 100 of the present application is used in a laboratory environment, and the indoor environment cannot reach a higher temperature, the glue of the present application is a high temperature resistant glue resistant to 180 ℃, such as epoxy glue.

In the present embodiment, when the first partition 112 and the first tank 111 are separate two members and the second partition 122 and the second tank 121 are separate two members, the first partition 112 and the second partition 122 are made of a ceramic material.

It should be noted that, the first partition 112 and the first groove 111 are defined as two separate components, the second partition 122 and the second groove 121 are defined as two separate components, and the first partition 112 is formed by the upward protrusion of the first groove 111, and the second partition 122 is formed by the downward protrusion of the second groove 121, so that the effects of the first structure and the second structure are identical, and are not repeated here.

Wherein, the fastener 16 may be a bolt, and the connecting piece 17 may be a nut, so as to realize that the fastener 16 and the connecting piece 17 are mutually matched and fixed.

In addition, by the arrangement mode, vibration and noise generated when the induction type electromagnetic pump 100 is operated can be reduced, so that the structural strength of the induction type electromagnetic pump 100 is further improved.

It should be noted that the fastening member 16 may be configured as a stud bolt, so that the fastening member 16 may pass through various components of the induction electromagnetic pump 100 from bottom to top or from top to bottom, and both ends of the fastening member 16 are fixed by two connection members 17, so as to implement the assembly of the induction electromagnetic pump 100.

Through the arrangement, the first iron core 131, the second iron core 132, the first partition 112 and the second partition 122 can be used as a supporting structure of the runner 15, so that the influence of the Bernoulli principle on the runner 15 is reduced, the running stability and the overall structural rigidity of the induction electromagnetic pump 100 are improved, and the service life of the induction electromagnetic pump 100 is prolonged.

It should be noted that, in the present application, only glue is used as an implementation manner, and specifically, a connection manner between the runner 15 and the first partition 112, a connection manner between the runner 15 and the second partition 122, and a connection manner between the runner 15 and the first core 131, and a connection manner between the runner 15 and the second core 132 may be selected according to practical situations, which is not limited by the present application.

When the base 11 and the cover plate 12 are connected, the above arrangement manner can prevent the portion of the winding 14 protruding from the first tooth 1312 and the second tooth 1322 from affecting the connection between the base 11 and the cover plate 12, so that the situation that the first iron core 131 and the second iron core 132 cannot be attached to the base 11 and/or the cover plate 12 can be avoided, that is, the first slot 111 of the present application can provide an arrangement space for the winding 14 wound on the first tooth 1312 and the second tooth 1322, the second slot 121 can provide an arrangement space for the winding 14 wound on the first tooth 1312 and the second tooth 1322, and the first iron core 131 and the second iron core 132 can be attached to the base 11 and/or the cover plate 12, so that the base 11 and the cover plate 12 can generate a pressing force on the first iron core 131 and the second iron core 132, and further the structural stress of the induction electromagnetic pump 100 can be changed, and the overall rigidity and the service life of the induction electromagnetic pump 100 can be improved.

Wherein the first partition 112 extends substantially in the front-rear direction of the induction type electromagnetic pump 100, and the second partition 122 extends substantially in the front-rear direction of the induction type electromagnetic pump 100, so that both the first partition groove 1111 and the second partition groove 1211 extend substantially in the front-rear direction of the induction type electromagnetic pump 100.

Illustratively, two first separating slots 1111 are provided for receiving the lower ends of windings 14 and two second separating slots 1211 are provided for receiving the upper ends of windings 14. More specifically, one first partition groove 1111 is for accommodating a lower end portion of the winding 14 wound around the first tooth 1312, the other first partition groove 1111 is for accommodating a lower end portion of the winding 14 wound around the second tooth 1322, one second partition groove 1211 is for accommodating an upper end portion of the winding 14 wound around the first tooth 1312, and the other second partition groove 1211 is for accommodating an upper end portion of the winding 14 wound around the second tooth 1322.

With the above arrangement, in the left-right direction of the induction electromagnetic pump 100, the first and second partition grooves 1111 and 1211 on the same side can be made to define the positions of the windings 14 on the first tooth 1312, and the first and second partition grooves 1111 and 1211 on the other side can be made to define the positions of the windings 14 on the second tooth 1322, thereby achieving positioning of the windings 14, and thus defining the positions of the first and second cores 131 and 132.

As one implementation, a longitudinal plane 102 is defined that is perpendicular to the left-right direction of induction electromagnetic pump 100, longitudinal plane 102 substantially bisects induction electromagnetic pump 100, and second tooth 1322 and first tooth 1312 are symmetrically disposed about longitudinal plane 102. The present application will be described with reference to the first tooth portion 1312.

As shown in fig. 6, a portion of the first tooth 1312 overlapping the first groove 111 as viewed from the vertical direction of the induction type electromagnetic pump 100 is a first portion, and a ratio of a length L1 of the first tooth 1312 in the horizontal direction of the induction type electromagnetic pump 100 to a length L2 of the first portion in the horizontal direction of the induction type electromagnetic pump 100 is 0.1 or more and 1 or less; the portion where the first tooth 1312 overlaps the second groove 121 is a second portion, and the ratio of the length L1 of the first tooth 1312 in the left-right direction of the induction type electromagnetic pump 100 to the length L3 of the second portion in the left-right direction of the induction type electromagnetic pump 100 is 0.1 or more and 1 or less. Specifically, the ratio of the length L1 of the first tooth 1312 in the left-right direction of the induction type electromagnetic pump 100 to the length L2 of the first portion in the left-right direction of the induction type electromagnetic pump 100 is 0.5 or more and 0.7 or less; the ratio of the length L1 of the first tooth portion 1312 in the left-right direction of the induction type electromagnetic pump 100 to the length L3 of the second portion in the left-right direction of the induction type electromagnetic pump 100 is 0.5 or more and 0.7 or less.

Through the arrangement, the situation that the windings 14 cannot be placed in the first groove body 111 and the second groove body 121 due to the fact that the length ratio of the first tooth portions 1312 to the first portions in the left-right direction of the induction electromagnetic pump 100 is too large can be avoided, so that the first iron core 131 and the base 11 are attached, the first iron core 131 and the cover plate 12 are attached, and the base 11 and the cover plate 12 can be fixed to the first iron core 131 conveniently; it is also possible to avoid that the ratio of the lengths of the first tooth 1312 and the first portion in the left-right direction of the induction electromagnetic pump 100 is too small to arrange the winding 14 capable of driving the liquid metal to flow, so that the first iron core 131 can drive the liquid metal to flow in cooperation with the second iron core 132.

It should be noted that the effect that the ratio of the lengths of the first tooth portion 1312 and the second portion in the left-right direction of the induction electromagnetic pump 100 is too large or too small is identical to the effect that the ratio of the lengths of the first tooth portion 1312 and the first portion in the left-right direction of the induction electromagnetic pump 100 is too large or too small, and will not be repeated here.

As an implementation manner, the material of the base 11 needs to be selected from pressure-resistant, high-temperature-resistant, non-magnetic and non-conductive materials, and in the application, the base 11 can be made of stainless steel or aluminum materials; the material of the cover plate 12 also needs to be selected from pressure-resistant, high-temperature-resistant, non-magnetic and non-conductive materials, and in the application, the cover plate 12 is made of stainless steel or aluminum materials; the material of the flow channel 15 is required to have corrosion resistance, no electric conduction capability and no magnetic conduction capability, and in the present application, polytetrafluoroethylene material is used for the flow channel 15.

Wherein the connection pipe 18 includes a first port 181 and a second port 182, an inner contour of the first port 181 is identical to an inner contour of an opening of the flow passage 15, the first port 181 and the opening of the flow passage 15 are connected or integrally formed, and an inner contour of the second port 182 is different from an inner contour of the first port 181 so that the second port 182 is connected with a pipe of an external device, wherein the inner contour of the pipe of the external device is different from the inner contour of the opening of the flow passage 15. With the above arrangement, the flow passage 15 can be connected to any pipe of the external device through the connection pipe 18, thereby improving the connection convenience of the induction electromagnetic pump 100 to the external device.

It should be noted that, the inner contour of the second port 182 may be adjusted according to the pipe shape of the actual external device, so as to improve the versatility of the induction electromagnetic pump 100.

By way of example, the second port 182 and the piping of the external device may also be connected by a flange, and the present application is not limited thereto.

As shown in fig. 6, as one implementation, a ratio of a depth H1 of the first groove 111 in the up-down direction of the induction type electromagnetic pump 100 to a height H2 of the base 11 in the up-down direction of the induction type electromagnetic pump 100 is 0.1 or more and 0.8 or less; the ratio of the depth H3 of the second groove 121 in the up-down direction of the induction type electromagnetic pump 100 to the height H4 of the cover 12 in the up-down direction of the induction type electromagnetic pump 100 is 0.1 or more and 0.8 or less. Specifically, the ratio of the depth H1 of the first groove 111 in the up-down direction of the induction type electromagnetic pump 100 to the height H2 of the base 11 in the up-down direction of the induction type electromagnetic pump 100 is 0.3 or more and 0.6 or less; the ratio of the depth H3 of the second groove 121 in the up-down direction of the induction type electromagnetic pump 100 to the height H4 of the cover 12 in the up-down direction of the induction type electromagnetic pump 100 is 0.3 or more and 0.6 or less.

By the arrangement, the structure strength of the base 11 can be prevented from being reduced due to the fact that the depth H1 of the first groove body 111 is too large, and the arrangement space of the windings 14 is prevented from being insufficient due to the fact that the depth H1 of the first groove body 111 is too small, so that the structure strength of the base 11 is improved under the condition that the first groove body 111 has enough space for accommodating the windings 14. In addition, by the arrangement, the structure strength of the cover plate 12 can be prevented from being reduced due to the fact that the depth H3 of the second groove body 121 is too large, and the arrangement space of the windings 14 is prevented from being insufficient due to the fact that the depth H3 of the second groove body 121 is too small, so that the structure strength of the cover plate 12 is improved under the condition that the second groove body 121 has enough space for accommodating the windings 14.

In the present embodiment, the ratio of the height H5 of the first partition 112 in the up-down direction of the induction type electromagnetic pump 100 to the depth H1 of the first groove 111 in the up-down direction of the induction type electromagnetic pump 100 is greater than 1 and equal to or less than 1.5; the ratio of the height H6 of the second partition 122 in the up-down direction of the induction type electromagnetic pump 100 to the depth H3 of the second groove 121 in the up-down direction of the induction type electromagnetic pump 100 is greater than 1 and equal to or less than 1.5. Specifically, the ratio of the height H5 of the first partition 112 in the up-down direction of the induction type electromagnetic pump 100 to the depth H1 of the first groove 111 in the up-down direction of the induction type electromagnetic pump 100 is 1.1 or more and 1.4 or less; the ratio of the height H6 of the second partition 122 in the up-down direction of the induction type electromagnetic pump 100 to the depth H3 of the second groove 121 in the up-down direction of the induction type electromagnetic pump 100 is 1.1 or more and 1.4 or less. With the above arrangement, it is possible to prevent the first and second cores 131 and 132 from being unable to abut against the first partition 112 due to the height H5 of the first partition 112 being too small, thereby improving the positioning accuracy of the first and second cores 131 and 132; it is also possible to prevent the flow path 15 from being reduced in the up-down direction of the induction type electromagnetic pump 100 due to the excessive height H5 of the first partition 112, thereby improving the flow rate of the flow path 15 and further improving the working efficiency of the induction type electromagnetic pump 100. Further, with the above arrangement, it is possible to prevent the height H6 of the second partition 122 from being too small to cause the first core 131 and the second core 132 to be in contact with the second partition 122, thereby improving the positioning accuracy of the first core 131 and the second core 132; it is also possible to prevent the flow path 15 from being reduced in the up-down direction of the induction type electromagnetic pump 100 due to the excessively small height H6 of the second partition portion 122, thereby improving the flow rate of the flow path 15 and further improving the operation efficiency of the induction type electromagnetic pump 100.

Illustratively, the width W1 of the first partition 112 in the left-right direction of the induction electromagnetic pump 100 is 2mm or more and 10mm or less; the width W2 of the second partition 122 in the lateral direction of the induction electromagnetic pump 100 is 2mm or more and 10mm or less. Specifically, the width W1 of the first partition 112 in the left-right direction of the induction electromagnetic pump 100 is 5mm or more and 7mm or less; the width W2 of the second partition 122 in the lateral direction of the induction electromagnetic pump 100 is 5mm or more and 7mm or less. By the above arrangement, the space for fixing the flow passage 15 can be prevented from being small due to the too small width of the first and second partition portions 112 and 122, so that a sufficient arrangement space can be provided for the flow passage 15, and the flow of the flow passage 15 can be prevented from being too small due to the too small arrangement space of the flow passage 15. In addition, by the above arrangement, the volumes of the winding 14, the first core 131 and the second core 132 can be prevented from being small due to the excessive widths of the first partition 112 and the second partition 122, so that the magnetic fields generated by the first core 131 and the second core 132 can drive the flow of the liquid metal after the winding 14 is electrified.

With the above arrangement, it is possible to allow the external cooling air to be supplied to the yoke portion of the first core 131 through the upper heat dissipation path 1913a, then to the first arc-shaped groove 125 through the upper heat dissipation path 1913a, and to the outside from the first arc-shaped groove 125; and/or may enable external cooling air to pass through the upper heat dissipation path 1913a to be delivered into the first arc-shaped groove 125 and from the first arc-shaped groove 125 to the outside.

Further, with the above arrangement, it is possible to allow the external cooling air to be sent to the yoke portion of the first core 131 through the lower heat dissipation path 1913b, then sent to the third arc-shaped groove 115 through the lower heat dissipation path 1913b, and sent from the third arc-shaped groove 115 to the outside; and/or may enable external cooling air to be delivered into the third arc-shaped groove 115 through the lower heat dissipation path 1913b and from the third arc-shaped groove 115 to the outside.

It should be noted that, the structure of the second side heat sink 192 is identical to that of the first side heat sink 191, so that the manner in which the second side heat sink 192 is connected to the base 11 and the cover 12 is identical to that in which the first side heat sink 191 is connected to the base 11 and the cover 12, the positional relationship between the second side heat sink 192 and the second heat sink 212 is a first positional relationship, the positional relationship between the first side heat sink 191 and the first heat sink 211 is a second positional relationship, and the first positional relationship is identical to the second positional relationship, which is not described in detail herein.

Specifically, the ratio of the thickness Q1 of the vertical sheet 1912 along the front-rear direction of the induction type electromagnetic pump 100 to the distance Q2 between two adjacent first heat dissipation grooves 211 along the front-rear direction of the induction type electromagnetic pump 100 is 0.7 or more and 0.9 or less. Through the arrangement, the phenomenon that the thickness Q1 of the vertical sheet body 1912 is too large to cause the vertical sheet body 1912 to block the first heat dissipation groove 211 can be avoided, so that the flow rate of external cooling air is improved, and the heat dissipation efficiency of the induction electromagnetic pump 100 is improved; the thickness Q1 of the vertical fin body 1912 is too small to prevent the strength of the vertical fin body 1912 from failing to meet the requirement, so that the first side heat sink 191 is prevented from being deformed due to insufficient strength of the first side heat sink 191, and the flow rate of external cooling air is improved under the condition of meeting the use strength of the first side heat sink 191, so as to improve the heat dissipation efficiency of the induction electromagnetic pump 100.

In the present application, since the first core 131 and the second core 132 are also abutted and connected to the left and right sides of the flow path 15, respectively, the total width of the first side fin 191, the first core 131, the flow path 15, the second core 132, and the second side fin 192 may be the entire width S1 (see fig. 5), the width of the base 11 or the cover 12 is the pump body width S2, and the ratio of the entire width S1 to the pump body width S2 is 0.8 or more and 1 or less in the left and right direction of the induction electromagnetic pump 100. Specifically, the ratio of the overall width S1 to the pump body width S2 is 0.9. By the arrangement, the first side radiating fins 191, the yoke part of the first iron core 131, the yoke part of the second iron core 132 and the second side radiating fins 192 can be prevented from exceeding the base 11 and the cover plate 12, so that the first radiating grooves 211 and the second radiating grooves 212 can not radiate the first side radiating fins 191, the yoke part of the first iron core 131, the yoke part of the second iron core 132 and the second side radiating fins 192, and the radiating efficiency of the induction electromagnetic pump 100 is further improved; it is also possible to prevent the space utilization between the base 11 and the cover 12 from being too low due to the excessively small overall width S1, thereby improving the space utilization of the induction type electromagnetic pump 100 and improving the structural compactness of the induction type electromagnetic pump 100.

Illustratively, in the present application, aluminum may be used for both the first side heat sink 191 and the second side heat sink 192, thereby improving the thermal conductivity of the first side heat sink 191 and the second side heat sink 192.

As shown in fig. 15, as an implementation manner, the induction electromagnetic pump 100 further includes a top heat sink 22 and a fixing ring 23, wherein the top heat sink 22 is located on the upper side of the cover plate 12 and is fixedly connected to the cover plate 12 through the fixing ring 23, and the fixing ring 23 is fixedly connected to the upper side of the cover plate 12. The heat generated by the winding 14 is transferred to the core assembly 13 and transferred to the top cooling fin 22 through the cover plate 12 abutting against the core assembly 13, so that the heat is transferred to the outside through the top cooling fin 22, that is, the top cooling fin 22 can be matched with the side cooling assembly 19, and the heat dissipation efficiency of the induction electromagnetic pump 100 is further improved.

Specifically, the induction electromagnetic pump 100 includes a fastening member 16 and a connecting member 17 matched with the fastening member 16, where the fastening member 16 is fixed by the connecting member 17 after penetrating through the fixing ring 23, the cover plate 12, the core assembly 13 and the base 11, so that the fixing ring 23, the cover plate 12, the core assembly 13 and the base 11 are connected by the same fastening member 16, so as to simplify the connection structure of the fixing ring 23, the cover plate 12, the core assembly 13 and the base 11, and further simplify the structure of the induction electromagnetic pump 100, so as to improve the structural compactness of the induction electromagnetic pump 100.

More specifically, the fixing ring 23 extends at least partially downward to form a plurality of fixing portions 231, the fixing portions 231 extend substantially along an "L", and the fastening members 16 are fastened by the connecting members 17 after passing through the fixing portions 231, the cover plate 12, the core assembly 13, and the base 11.

Wherein, the second sheet 222 is in interference fit with the inner side surfaces of the left side and the right side of the fixed ring 23; the first sheet 221 is interference fit with the inner side surfaces of the front and rear sides of the fixing ring 23. With the above arrangement, the position of the top heat sink 22 can be defined by the fixing ring 23, so that the operation of the top heat sink 22 is more stable.

Specifically, a cooling channel 223 is formed between two adjacent second sheets 222, and the cooling channels 223 are respectively communicated with the outside and the upper surface of the cover plate 12, so that the external cooling air delivered to the top cooling fins 22 is delivered to the upper surface of the cover plate 12 through the cooling channels 223, and then is delivered to the outside through the gap between the fixing ring 23 and the upper surface of the cover plate 12. Wherein, since the fixing ring 23 is at least partially extended downward to form the fixing portion 231, the fixing portion 231 can allow a gap between the fixing ring 23 and the upper surface of the cover plate 12, thereby allowing external cooling wind to be transmitted to the outside through the gap between the fixing ring 23 and the upper surface of the cover plate 12.

In this embodiment, when viewed from the vertical direction of the induction electromagnetic pump 100, the top cooling fin 22 and the first slot 111 are at least partially overlapped, and the top cooling fin 22 and the second slot 121 are at least partially overlapped, so that after the heat generated by the winding 14 is transferred to the core assembly 13, the heat can be transferred to the top cooling fin 22 through the cover plate 12, and further, the heat dissipation effect of the induction electromagnetic pump 100 is further improved through the cooperation of the top cooling fin 22 and the side cooling assembly 19.
