Description

[Technical Field]

[0001] The present invention relates to a magnetic component and a method for manufacturing the same. [Background technology]

[0002] When a magnetic component is operating, its magnetic core and windings generate a large amount of heat. The heat dissipation structure of a magnetic component usually consists of a heat dissipation adhesive, a heat dissipation aluminum plate, and a coolant. Some of the heat generated by the magnetic component is dissipated by the air, and another part is introduced into the heat dissipation aluminum plate via the heat dissipation adhesive and then removed via the coolant.

[0003] In the prior art, due to manufacturing tolerances, etc., the distance between the magnetic core or winding and the heat dissipation aluminum plate in each magnetic component varies, and in particular, the distance between the magnetic core or winding and the heat dissipation aluminum plate varies greatly between magnetic components from different lots, resulting in different heat dissipation effects.

[0004] For example, as shown in FIG. 1, in the magnetic component 1A, the tolerance of the winding 12 wound around the magnetic core 11 is large, and the distance D1 between the top of the magnetic component 1A and the client's heat dissipation aluminum plate 100 is small.

[0005] In magnetic component 1B, the tolerance of winding 12 wound around magnetic core 11 is small, and the distance D2 between the top of magnetic component 1B and the client's heat dissipation aluminum plate 100 is large. In other words, due to differences in winding tolerance, magnetic components 1A and 1B shown in FIG. 1 are at different distances from the client's heat dissipation aluminum plate 100, and therefore the lengths of the heat dissipation paths are different, resulting in different heat dissipation effects between magnetic components 1A and 1B.

DETAILED DESCRIPTION OF THE INVENTION

[0055] Hereinafter, exemplary embodiments will be described in detail with reference to the drawings. However, the exemplary embodiments may be implemented in various forms and are not limited to the embodiments described herein. Rather, these embodiments are provided to fully complete the present invention and fully convey the concept of the exemplary embodiments to those skilled in the art. Since the same reference numerals in the drawings indicate the same or similar elements, detailed descriptions thereof will be omitted.

[0059] The magnetic core 11 has a bottom surface and a top surface that are opposite to each other, and the bottom surface and top surface of the magnetic core 11 correspond to the bottom 14 and top 13 of the magnetic device 1, respectively. That is, the bottom surface of the magnetic core 11 is close to the bottom 14 of the magnetic device 1, and the top surface of the magnetic core is close to the top 13 of the magnetic device 1. In the embodiment shown in Figures 2A to 2D, the magnetic core 11 is an annular magnetic core.

[0060] The base 2 includes a base plate 21 and a center pillar 22 provided vertically in the center of the base plate 21. The base 2 may be provided with a plurality of through holes such as a terminal hole 211, a jig hole 212, an adhesive injection hole 213, and the like.

[0061] The center pillar 22 may further be provided with at least one isolation plate 221 along the circumferential direction, which is for isolating different windings to meet safety requirements. The center pillar 22 has an adhesive injection channel passing through it, which is connected to the adhesive injection hole 213 on the base 2. Adhesive can be injected into the magnetic component through the adhesive injection hole 213 and the adhesive injection channel.

[0062] In some other embodiments, the base 2 may not include the center pillar 22, but may include only the base plate 21. The corresponding magnetic device 1 may not be provided with a central through-hole.

[0063] The positioning frame 3 has a cylindrical peripheral wall 31 and a positioning portion. The peripheral wall 31 may be provided with a heat dissipation vent 30. The peripheral wall 31 has a first end and a second end provided opposite each other, and the first end of the peripheral wall 31 is connected perpendicularly to the outer edge of the positioning portion in the circumferential direction, while the second end of the peripheral wall 31 is connected to the outer edge of the base plate 21 in the circumferential direction, so that the positioning frame 3, together with the base plate 21, surrounds the accommodation space. Note that the vertical direction in the perpendicular connection is direction H perpendicular to the base plate 21.

[0064] The method of connecting the peripheral wall 31 and the base plate 21 may be various, for example, by providing a plurality of positioning notches 32 at the second end of the peripheral wall 31 and providing a plurality of positioning tables 214 on the base plate 21, and connecting the peripheral wall 31 and the base plate 21 by engaging the plurality of positioning notches 32 with the plurality of positioning tables 214.

[0065] When assembling the magnetic component according to the first embodiment of the present invention, the center pillar 22 of the base 2 is drilled from the bottom 14 of the magnetic device 1 into the central through hole of the magnetic device 1, and the multiple terminals 121 are each protruded from corresponding terminal holes 211 in the base plate 21 of the base 2, and the magnetic device 1 is mounted in the storage space surrounded by the positioning frame 3 and the base plate 21, so that the top 13 of the magnetic device 1 comes into contact and engages with the positioning portion of the positioning frame 3.

[0066] The magnetic components of the present invention are provided with a positioning frame 3, and the top 13 of the magnetic device 1 is in contact with and engages with the positioning portion of the positioning frame 3. That is, by positioning the top of the magnetic components, it is easy to control the consistency of the distance between the tops of multiple magnetic components and the client's heat dissipation aluminum plate, thereby improving the consistency of the heat dissipation effect of multiple magnetic components.

[0067] A specific example of the contact engagement between the top portion 13 of the magnetic device 1 and the positioning portion of the positioning frame 3 in this first embodiment will be described below.

[0068] 2B and 2D, the magnetic component of this first embodiment further includes a protective case 4, which encases the outer surface of the magnetic core 11 to provide protection for the magnetic core 11. The protective case 4 has a bottom surface and a top surface that are opposite to each other and correspond to the bottom 14 and top 13 of the magnetic device 1, respectively. A rib 42 is provided on the top surface of the protective case 4.

[0069] As shown in FIG. 3, the positioning portion of the positioning frame 3 includes a plurality of positioning ribs 33 arranged radially.

[0070] 4, the total height of the ribs 42 of the protective case 4 and the positioning ribs 33 of the positioning frame 3 in the direction H perpendicular to the base plate 21 is greater than the height of the windings 12 protruding from the top surface of the protective case 4. The ribs 42 of the protective case 4 come into contact with and engage with the positioning ribs 33 of the positioning frame 3, thereby achieving engagement between the top portion 13 of the magnetic device 1 and the positioning portion of the positioning frame 3.

[0071] In this first embodiment, the total height of the ribs 42 and the positioning ribs 33 is greater than the height of the winding 12 protruding from the top surface of the protective case 4, and the contact engagement between the ribs 42 and the positioning ribs 33 realizes positioning relative to the top 13 of the magnetic device 1, effectively shields the winding tolerance of the winding 12, matches the height of each magnetic component, and matches the distance between the top of each magnetic component and the client's heat dissipation aluminum plate, thereby ensuring a uniform heat dissipation effect.

[0072] In some other embodiments, the bottom surface of the protective case 4 may be provided with a rib 42. In this way, there is no need to distinguish the orientation of the protective case 4 during assembly, i.e., whether the top surface of the protective case 4 faces the positioning portion or the bottom surface of the protective case 4 faces the positioning portion, the rib 42 can be brought into contact with and engaged with the positioning rib 33, which makes the assembly of the magnetic component more convenient and quick.

[0073] In some other embodiments, as shown in Figures 2B, 2C, and 2D, the magnetic component further includes an insulating structure 6, which is located on the top of the magnetic component. The insulating structure 6 can ensure good heat dissipation and achieve reliable safety insulation performance. Meanwhile, the insulating structure 6 can also increase the safety distance from the winding to the heat-dissipating aluminum plate.

Here, the metal plate may be made of a material with excellent thermal conductivity, such as aluminum, copper, or stainless steel, and the insulating sheet may be attached to the outer surface of the metal plate. The insulating sheet may be a sheet that can withstand high voltage and has good insulating properties, such as high-temperature insulating tape, Nomex paper, or an epoxy resin sheet. The insulating structure 6 may also be an aluminum-based electronic circuit board. The insulating structure 6 may be made of a thermally conductive insulating material, such as alumina ceramics, aluminum nitride ceramics, boron nitride ceramics, thermally conductive plastics, or a thermally conductive silicone sheet with an insulating layer.

[0075] Typically, the insulation between the winding and the heat-dissipating aluminum plate is ensured by making the projected area of ​​the insulating structure 6 onto the heat-dissipating surface (a plane perpendicular to the central axis of the magnetic component), for example the top surface of the magnetic component, larger than the projected area of ​​the winding onto that surface.

[0076] 5, the second embodiment of the magnetic component of the present invention differs from the first embodiment in the following respects: the magnetic component further includes a thermally conductive adhesive layer 5 that wraps around the top 13 of the magnetic device 1 and fills the gap between the winding 12 and the protective case 4, and also wraps around a portion of the protective case 4 and the entire magnetic device 1.

[0077] By adding the thermally conductive adhesive layer 5, the heat generated by the magnetic component can be conducted to the outside more quickly, which contributes to improving the heat dissipation efficiency.

[0078] Other structures of the magnetic component according to the second embodiment of the present invention are substantially the same as those of the first embodiment, and therefore detailed description thereof will be omitted here.

[0079] As shown in Figure 6, the third embodiment of the magnetic component of the present invention differs from the first or second embodiment as follows: The protective case 4 does not have ribs 42, and the top surface of the protective case 4 comes into contact with and engages with the positioning ribs 33. The height of the positioning ribs 33 in the direction H perpendicular to the base plate 21 is greater than the height of the windings 12 protruding from the top surface of the protective case 4. The windings 12 protruding from the top surface of the protective case 4 are housed between two adjacent positioning ribs 33.

[0080] Other structures of the magnetic component according to the third embodiment of the present invention are substantially the same as those of the first and second embodiments, and therefore detailed description thereof will be omitted here.

[0084] Other structures of the magnetic component according to the fifth embodiment of the present invention are substantially the same as those of the third or fourth embodiment, and therefore detailed description thereof will be omitted here.

[0085] A first embodiment of the method for manufacturing a magnetic component of the present invention includes: providing a magnetic device (1) having a top (13) and a bottom (14) opposite to each other, the magnetic core (11) having a bottom surface (14) opposite to each other, the bottom surface (14) and the top surface (14) of the magnetic device (1), and the winding (12) having a bottom surface (14) opposite to each other, the bottom surface (14) and the top surface (14) of the magnetic device (1), the top surface (14) of the magnetic device (1), and the winding (12) having a bottom surface (14) opposite to each other, the bottom surface (14) and the top surface (14) of the magnetic device (1), the top surface (14) of the magnetic device (1), the bottom surface (14) and the top surface (14) of the magnetic device (1), the top surface (14) of the magnetic device (1), the top surface (14) of the magnetic device (1), the bottom surface (14) of the magnetic device (1), ... top surface (14) of the magnetic device (1 providing a base 2 including a base plate 21; a step of providing a positioning frame (3), the positioning frame (3) having a positioning portion and a peripheral wall (31), the peripheral wall (31) including a first end and a second end opposite to each other, the first end and the second end corresponding to the top and bottom of the magnetic device (1), the peripheral wall (31) being connected perpendicularly to the outer peripheral edge of the positioning portion by the first end, and the second end of the peripheral wall (31) being connected to the outer peripheral edge of the base plate (21) in the circumferential direction, so that the positioning frame (3) together with the base plate (21) surrounds the accommodating space, and the magnetic device (1) is positioned in the accommodating space; and a positioning step of using an assembly jig to push the magnetic device 1 through a jig hole on the base 2, thereby bringing the top 13 of the magnetic device 1 into contact with and into engagement with the positioning portion of the positioning frame 3.

[0086] The first embodiment of the magnetic component manufacturing method of the present invention includes the step of providing a positioning frame, and the top 13 of the magnetic device 1 contacts and engages with the positioning portion of the positioning frame 3, i.e., by positioning the top of the magnetic component, it is easy to control the consistency of the distance between the top of multiple magnetic components and the client's heat dissipation aluminum plate, thereby improving the consistency of the heat dissipation effect of multiple magnetic components.

[0087] In some embodiments, the magnetic device 1 has a central through hole, and the base 2 further includes a center pillar 22 arranged vertically in the center of the base plate 21, the center pillar 22 being drilled from the bottom 14 of the magnetic device 1 to the central through hole of the magnetic device 1.

[0088] In the positioning step of some embodiments, the upper surface of the winding 12 is brought into contact with and engaged with the positioning portion of the positioning frame 3 .

[0089] In this first embodiment, the positioning portion of the positioning frame 3 includes a plurality of positioning ribs 33 arranged radially, and the magnetic core 11 has a bottom surface and a top surface opposite to each other, which correspond to the bottom 14 and the top 13 of the magnetic device 1, respectively, and in the positioning step, the top surface of the magnetic core 11 is brought into contact and engaged with the positioning ribs 33 of the positioning frame 3.

[0090] The assembly jig is removed after the assembly of the magnetic components is completed.

[0091] In a second embodiment of the method for manufacturing a magnetic component of the present invention, the magnetic component further includes a protective case 4, which encases the magnetic core 11 and provides protection for the magnetic core 11. The protective case 4 has opposite bottom and top surfaces, which correspond to the bottom 14 and top 13 of the magnetic device 1, respectively. The positioning portion of the positioning frame 3 includes a plurality of positioning ribs 33 arranged radially. Ribs 42 are provided on the top surface of the protective case 4, and the total height of the ribs 42 and the positioning ribs 33 in a direction perpendicular to the base plate 21 is greater than the height by which the winding 12 protrudes from the top surface of the protective case 4.

[0092] The second embodiment of the method for manufacturing a magnetic component of the present invention differs from the first embodiment of the method for manufacturing as follows: In the positioning step, the rib 42 of the protective case 4 is brought into contact with and engaged with the positioning rib 33 of the positioning frame 3 .

[0093] As shown in Figure 9, the winding tolerances of the two windings in the two magnetic components are different, i.e., the winding tolerance of the left winding 12 in the magnetic core 11 is large and the distance D1 between the top of the winding 12 and the client's heat dissipation aluminum plate 100 is small; the winding tolerance of the right winding 12 in the magnetic core 11 is small and the distance D2 between the winding 12 and the client's heat dissipation aluminum plate 100 is large.

[0094] In this embodiment, the magnetic component is positioned by its top, specifically, the rib 42 on the top surface of the protective case 4 contacts and engages with the positioning rib 33 on the positioning frame 3 at the top of the magnetic component, thereby bringing the winding 12 and magnetic core 11, which generate a large amount of heat, as close as possible to the top of the magnetic component, i.e., as close as possible to the client's heat-dissipating aluminum plate 100, thereby shortening the heat-dissipating path, improving the heat-dissipating effect, and significantly reducing the thickness of the client's heat-dissipating adhesive layer, thereby reducing costs.

[0095] On the other hand, as shown in Figure 9, the distances from the two magnetic components with different winding tolerances to the client's heat dissipation aluminum plate 100 are the same, both distances D0. That is, the two magnetic components have the same heat dissipation path length and good heat dissipation consistency. Furthermore, the heights of the two magnetic components are the same, which is the sum of the thickness of the base plate and the height of the positioning frame. The manufacturing method of this embodiment ensures accurate heights for each magnetic component, good height consistency among multiple magnetic components, and ensures that the top surfaces of each magnetic component are at the same height relative to the bottom surfaces of the magnetic components during installation. This not only contributes to improved heat dissipation but also simplifies installation.

[0096] In some other manufacturing method embodiments, if no ribs 42 are provided on the upper surface of the protective case 4, in the positioning step, the upper surface of the protective case 4 is brought into contact and engagement with the positioning portion of the positioning frame 3, and further, if the positioning portion includes multiple positioning ribs 33, the upper surface of the protective case 4 is brought into contact and engagement with the positioning ribs 33.

[0098] In some other embodiments of the manufacturing method, the magnetic device 1 has a central through-hole, and the base 2 further includes a center pillar 22 arranged vertically in the center of the base plate 21, and the center pillar 22 is drilled from the bottom 14 of the magnetic device 1 to the central through-hole of the magnetic device 1. The base plate 21 is provided with an adhesive injection hole 213 penetrating the base plate 21, and the center pillar 22 is provided with an adhesive injection channel communicating with the adhesive injection hole 213. The manufacturing method further includes a step of injecting adhesive into the accommodating space through the adhesive injection hole 213 and the adhesive injection channel to form a thermally conductive adhesive layer 5, which at least encases the top 13 of the magnetic device 1 and fills the gap between the winding 12 and the magnetic core 11 or the protective case 4, and may further encase the entire magnetic device 1.

In the positioning step, the top 13 of the magnetic device 1 is brought into contact with and engaged with the positioning structure of the assembly jig.

In the positioning step, the magnetic device 1 is placed inside the cylindrical wall 64, and the biasing pillar 611 presses the magnetic device 1 through the jig hole 212 on the base 2, thereby causing the top 13 of the magnetic device 1 to contact and engage with the positioning structure 621 on the assembly jig.
