In addition to these detailed descriptions, the present utility model can also be widely implemented in other embodiments.

In the description of the specification, in order to enable the reader to have a more complete understanding of the present utility model, many specific details are provided; however, the present utility model may still be implemented on the premise of omitting some or all of these specific details. In addition, well-known common steps or elements are not described in detail to avoid unnecessary limitations on the present utility model. The same or similar elements in the drawings will be represented by the same or similar symbols.

[0050] First Embodiment:

[0051] Please refer to FIGS. 1A to 1D, which show a magnetic element 100 according to the first embodiment of the present utility model. FIGS. 1A and 1C illustrate a three-dimensional view of the magnetic element 100. Figure 1B Illustrating the corresponding Figure 1A top view, Figure 1D Illustrating the corresponding Figure 1C top view, in which, in order to clearly show the internal configuration, the upper cover 111 of the magnetic core of the magnetic element 100 is omitted in FIGS. 1A and 1B.

[0052] The magnetic element 100 of this embodiment is, for example, a transformer or an iron core inductor or a combination thereof. The magnetic element 100 includes a magnetic core, a first winding W1, and a second winding W2. The magnetic core includes an upper cover 111 and a lower cover 112. The lower cover 112 has a first winding post C1 and a second winding post C2, such that the first winding W1 is wound around the first winding post C1, and the second winding W2 is wound around the second winding post C2. The first winding W1 and the second winding W2 can each be a combination of a primary coil and a secondary coil, and the number of the primary coil and the secondary coil can be determined according to the actual application requirements, and the present utility model is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 are, for example, both cylindrical, but the present utility model is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 can also both be prismatic; or, the shapes of the first winding post C1 and the second winding post C2 can also be different, for example, one is cylindrical and the other is prismatic.

[0053] As Figure 1B shown, the first winding post C1 and the second winding post C2 are spaced apart along the length direction LD of the magnetic element 100, and the first winding post C1 and the second winding post C2 are offset from each other along the width direction WD of the magnetic element 100, where the width direction WD (parallel to the X-axis in the figure) is perpendicular to the length direction LD (parallel to the Y-axis in the figure). Specifically, the center O of the first winding post C1 C1with the center O of the second winding post C2 C2 has a distance d in the length direction LD L , and the center O of the first winding post C1 C1 with the center O of the second winding post C2 C2 has a distance d in the width direction WD W , that is, the first winding post C1 and the second winding post C2 are arranged diagonally in the magnetic element 100, different from the horizontal arrangement adopted in the prior art. Thus, in a situation where the heat dissipation air flow is preset to blow along the length direction LD, through this diagonal arrangement, the first winding W1 and the second winding W2 in the magnetic element 100, as well as the first winding post C1 and the second winding post C2, can all receive the air flow, thereby improving the problem of uneven heat dissipation.

[0054] Further describing this embodiment, the lower cover 112 has a base 112B and two side posts. The first winding post C1 and the second winding post C2 are formed on the base 112B. In this embodiment, these two side posts are the left side post 112L and the right side post 112R. The left side post 112L and the right side post 112R are formed at both ends of the base 112B, and the first winding post C1 and the second winding post C2 are located between the left side post 112L and the right side post 112R. The first winding post C1 is adjacent to the left side post 112L, and the second winding post C2 is adjacent to the right side post 112R. Corresponding to the diagonal arrangement of the first winding post C1 and the second winding post C2 in the magnetic element 100, the left side post 112L and the right side post 112R are also arranged offset from each other along the width direction WD. As Figure 1A shown, in the height direction HD of the magnetic element 100, the height h of the left side post 112L 112L is equal to the height h of the right side post 112R 112R , and the heights of these two side posts are greater than the height h of the base 112B 112B , where the height direction HD (parallel to the Z-axis in the figure) is perpendicular to the length direction LD and the width direction WD.

[0055] As Figure 1B shown, the first winding post C1 completely projects and overlaps with the left side post 112L in the length direction LD, and the second winding post C2 completely projects and overlaps with the right side post 112R in the length direction LD. Moreover, the base 112B has two opposite folded side walls. In this embodiment, these two folded side walls are the front folded side wall P1 and the rear folded side wall P2 respectively. The front folded side wall P1 and the rear folded side wall P2 are connected between the left side post 112L and the right side post 112R. The front folded side wall P1 and the rear folded side wall P2 are respectively a multi-sided wall surface structure. Through the folded line design to adapt to the diagonal arrangement of the first winding post C1 and the second winding post C2 in the magnetic element 100, the floor area of the base 112B can be reduced.

[0056] As shown Figure 1C in the figure, corresponding to the structure of the lower cover 112, the upper cover 111 also has a base 111B, a left column 111L, and a right column 111R with the same design. The left column 111L of the upper cover 111 abuts against the left column 112L of the lower cover 112, and the right column 111R of the upper cover 111 abuts against the right column 112R of the lower cover 112, so that the upper cover 111 and the lower cover 112 can be stacked up and down. As shown Figure 1D in the figure, corresponding to the structure of the lower cover 112, the upper cover 111 also has a third winding post C3 and a fourth winding post C4. Similar to the design of the lower cover 112, the third winding post C3 and the fourth winding post C4 are spaced apart along the length direction LD, and the third winding post C3 and the fourth winding post C4 are offset from each other along the width direction WD. Thereby, the first winding post C1 of the lower cover 112 can be aligned with the third winding post C3 of the upper cover 111, and the second winding post C2 of the lower cover 112 can be aligned with the fourth winding post C4 of the upper cover 111. In this embodiment, when the upper cover 111 and the lower cover 112 are stacked, there is a gap d between the first winding post C1 and the third winding post C3 13 , and there is a gap d between the second winding post C2 and the fourth winding post C4 24 , but the present utility model is not limited thereto. That is, the first winding post C1 can also abut against the third winding post C3, and the second winding post C2 can also abut against the fourth winding post C4.

[0057] Second Embodiment:

[0058] Please refer to FIGS. 2A to 2D, which show a magnetic component 200 according to the second embodiment of the present utility model. FIGS. 2A and 2C show perspective views of the magnetic component 200, Figure 2B showing the corresponding Figure 2A top view, Figure 2D showing the corresponding Figure 2C top view, wherein in order to clearly show the internal configuration, the upper cover 211 of the magnetic core of the magnetic component 200 is omitted in FIGS. 2A and 2B.

[0059] The magnetic component 200 of this embodiment is, for example, a transformer, an iron core inductor, or a combination thereof. The magnetic component 200 includes a magnetic core, a first winding W1, and a second winding W2. The magnetic core includes an upper cover body 211 and a lower cover body 212. The lower cover body 212 has a first winding post C1 and a second winding post C2, such that the first winding W1 is wound around the first winding post C1, and the second winding W2 is wound around the second winding post C2. The first winding W1 and the second winding W2 can each be a combination of a primary coil and a secondary coil, and the number of the primary coil and the secondary coil can be determined according to the actual application requirements, and the present invention is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 are, for example, both cylindrical, but the present invention is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 can also both be prismatic; or, the shapes of the first winding post C1 and the second winding post C2 can also be different, for example, one is cylindrical and the other is prismatic.

[0060] As Figure 2B shown, the first winding post C1 and the second winding post C2 are arranged at intervals along the length direction LD of the magnetic component 200, and the first winding post C1 and the second winding post C2 are offset from each other along the width direction WD of the magnetic component 200, wherein the width direction WD (parallel to the coordinate X axis in the figure) is perpendicular to the length direction LD (parallel to the coordinate Y axis in the figure). Specifically, the center O C1 of the first winding post C1 and the center O C2 of the second winding post C2 have a distance d L in the length direction LD, and the center O C1 of the first winding post C1 and the center O C2 of the second winding post C2 have a distance d W in the width direction WD, that is, the first winding post C1 and the second winding post C2 are arranged in a diagonal configuration in the magnetic component 200, which is different from the horizontal configuration adopted in the prior art. Thus, in a situation where the preset heat dissipation air flow direction is along the length direction LD, through this diagonal configuration, the first winding W1 and the second winding W2 and the first winding post C1 and the second winding post C2 in the magnetic component 200 can all receive the air flow, thereby improving the problem of uneven heat dissipation.

[0061] Further describing this embodiment, the lower cover body 212 has a base 212B and two side columns. The first winding column C1 and the second winding column C2 are formed on the base 212B. In this embodiment, these two side columns are the left side column 212L and the right side column 212R. The left side column 212L and the right side column 212R are formed at both ends of the base 212B, and the first winding column C1 and the second winding column C2 are located between the left side column 212L and the right side column 212R. The first winding column C1 is adjacent to the left side column 212L, and the second winding column C2 is adjacent to the right side column 212R. Corresponding to the diagonal configuration of the first winding column C1 and the second winding column C2 in the magnetic component 200, the left side column 212L and the right side column 212R are also offset from each other along the width direction WD. As Figure 2A shown, in the height direction HD of the magnetic component 200, the height h 212L of the left side column 212L 212R is equal to the height h 212B of the right side column 212R, and the heights of these two side columns are greater than the height h

[0062] of the base 212B, where the height direction HD (parallel to the coordinate Z-axis in the figure) is perpendicular to the length direction LD and the width direction WD. Figure 2B shown, the first winding column C1 completely projects and overlaps the left side column 212L in the length direction LD, and the second winding column C2 completely projects and overlaps the right side column 212R in the length direction LD. Moreover, the base 212B has two opposite diagonal side walls. In this embodiment, these two diagonal side walls are the front diagonal side wall I1 and the rear diagonal side wall I2 respectively. The front diagonal side wall I1 and the rear diagonal side wall I2 are connected between the left side column 212L and the right side column 212R. The so-called "diagonal" side wall means having an inclination with respect to the left side column 212L and the right side column 212R (the side columns extend parallel to the coordinate X-axis in the figure), rather than forming a right angle. The front diagonal side wall I1 and the rear diagonal side wall I2 are respectively a single-side wall structure, and through the diagonal design to adapt to the diagonal configuration of the first winding column C1 and the second winding column C2 in the magnetic component 200, the floor area of the base 212B can be reduced.

[0063] As Figure 2C shown, corresponding to the structure of the lower cover body 212, the upper cover body 211 also has a base 211B, a left side column 211L, and a right side column 211R with the same design. The left side column 211L of the upper cover body 211 abuts against the left side column 212L of the lower cover body 212, and the right side column 211R of the upper cover body 211 abuts against the right side column 212R of the lower cover body 212, so that the upper cover body 211 and the lower cover body 212 can be stacked up and down. As Figure 2DAs shown, corresponding to the structure of the lower cover 212, the upper cover 211 also has a third winding post C3 and a fourth winding post C4. Similar to the lower cover 212, the third winding post C3 and the fourth winding post C4 are spaced apart along the length direction LD, and the third winding post C3 and the fourth winding post C4 are offset from each other along the width direction WD. Thereby, the first winding post C1 of the lower cover 212 can be aligned with the third winding post C3 of the upper cover 211, and the second winding post C2 of the lower cover 212 can be aligned with the fourth winding post C4 of the upper cover 211. In this embodiment, when the upper cover 211 and the lower cover 212 are stacked, there is a gap d13 between the first winding post C1 and the third winding post C3, and there is a gap d24 between the second winding post C2 and the fourth winding post C4, but the present invention is not limited thereto. That is, the first winding post C1 may also be in contact with the third winding post C3, and the second winding post C2 may also be in contact with the fourth winding post C4.

[0064] Third Embodiment:

[0065] Please refer to FIGS. 3A to 3D, which show a magnetic component 300 according to the third embodiment of the present invention. FIGS. 3A and 3C illustrate perspective views of the magnetic component 300. Figure 3B showing corresponding Figure 3A top views, Figure 3D showing corresponding Figure 3C top views, wherein in order to clearly show the internal configuration, the upper cover 311 of the magnetic core of the magnetic component 300 is omitted in FIGS. 3A and 3B.

[0066] The magnetic component 300 of this embodiment is, for example, a transformer or an iron core inductor or a combination thereof. The magnetic component 300 includes a magnetic core, a first winding W1, and a second winding W2. The magnetic core includes an upper cover 311 and a lower cover 312. The lower cover 312 has a first winding post C1 and a second winding post C2 such that the first winding W1 is wound around the first winding post C1, and the second winding W2 is wound around the second winding post C2. The first winding W1 and the second winding W2 can each be a combination of a primary coil and a secondary coil, and the number of the primary coil and the secondary coil can be determined according to actual application requirements, and the present invention is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 are, for example, both cylindrical, but the present invention is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 can also be both prismatic; or, the shapes of the first winding post C1 and the second winding post C2 can be different, for example, one is cylindrical and the other is prismatic.

[0067] As Figure 3BAs shown, the first winding post C1 and the second winding post C2 are arranged at intervals along the length direction LD of the magnetic element 300, and the first winding post C1 and the second winding post C2 are arranged offset from each other along the width direction WD of the magnetic element 300, where the width direction WD (parallel to the coordinate X-axis in the figure) is perpendicular to the length direction LD (parallel to the coordinate Y-axis in the figure). Specifically, the center O of the first winding post C1 C1 and the center O of the second winding post C2 C2 have a distance d in the length direction LD L and the center O of the first winding post C1 C1 and the center O of the second winding post C2 C2 have a distance d in the width direction WD W That is, the first winding post C1 and the second winding post C2 are arranged in a diagonal configuration in the magnetic element 300, different from the horizontal configuration adopted in the prior art.

[0068] To further describe this embodiment, the lower cover 312 has a base 312B and two side posts. The first winding post C1 and the second winding post C2 are formed on the base 312B. In this embodiment, these two side posts are the left side post 312L and the right side post 312R. The left side post 312L and the right side post 312R are formed at both ends of the base 312B, and the first winding post C1 and the second winding post C2 are located between the left side post 312L and the right side post 312R. The first winding post C1 is adjacent to the left side post 312L, and the second winding post C2 is adjacent to the right side post 312R. Corresponding to the diagonal configuration of the first winding post C1 and the second winding post C2 in the magnetic element 300, the left side post 312L and the right side post 312R are also arranged offset from each other along the width direction WD.

[0069] The lower cover 312 further has an intermediate post M. The intermediate post M is formed on the base 312B. The intermediate post M is located between the left post 312L and the right post 312R, and between the first winding post C1 and the second winding post C2. In this embodiment, the intermediate post M includes a first side post portion M1 and a second side post portion M2, and there is a gap between the first side post portion M1 and the second side post portion M2. Or rather, the intermediate post M is a mountain-shaped structure with a notch in the center, and it is formed extending along the width direction WD. Thus, with the gap design between the first side post portion M1 and the second side post portion M2 (or the notch design in the center of the intermediate post M), in a situation where the preset heat dissipation air flow blows along the length direction LD, the air flow can first pass through the combination of one winding and the winding post, and then pass through this gap (or notch) to pass through the combination of the other winding and the winding post, so that the first winding W1 and the second winding W2 in the magnetic component 300, as well as the first winding post C1 and the second winding post C2, can all receive the air flow, thereby improving the problem of uneven heat dissipation. For example, the first side post portion M1 and / or the second side post portion M2 are corner posts, but the present invention does not limit this, as long as the base 312B forms a protruding structure like the intermediate post M. As Figure 3A shown, in the height direction HD of the magnetic component 300, the height h of the left post 312L 312L is equal to the height h of the right post 312R 312R , and the heights of these two side posts are greater than the height h of the base 312B 312B ; the height h of the intermediate post M M is equal to the height h of the left post 312L 312L and the height h of the right post 312R 312R , but it is not limited to this. For example, in a situation with higher heat dissipation requirements, the height h of the intermediate post M M can be designed to be less than the height h of the left post 312L 312L or the height h of the right post 312R 312R so that more air flow (preset to blow along the length direction LD) can pass through.

[0070] As Figure 3BAs shown, the first winding post C1 completely projects and overlaps the left post 312L in the length direction LD, and the second winding post C2 completely projects and overlaps the right post 312R in the length direction LD. The first winding post C1 at least partially projects and overlaps the first side post portion M1 in the length direction LD, and the second winding post C2 at least partially projects and overlaps the second side post portion M2 in the length direction LD. The base 312B has two opposite folded side walls. In this embodiment, these two folded side walls are the front folded side wall P1 and the rear folded side wall P2 respectively. The front folded side wall P1 and the rear folded side wall P2 are connected between the left post 312L and the right post 312R. The front folded side wall P1 and the rear folded side wall P2 are respectively a multi-sided wall structure, and through the folded design to accommodate the diagonal configuration of the first winding post C1 and the second winding post C2 in the magnetic element 300, the floor area of the base 312B can be reduced. In this embodiment, the middle post M shares part of the wall surfaces of the front folded side wall P1 and the rear folded side wall P2 with the base 312B, and is a folded line segment in the center of the front folded side wall P1 and the rear folded side wall P2. In addition, the design of the middle post M can increase the cross-sectional area of the magnetic flux passing through the center of the magnetic element 300 through the first side post portion M1 and the second side post portion M2, thereby reducing the magnetic flux density and further reducing the core loss.

[0071] As Figure 3C shown, corresponding to the structure of the lower cover 312, the upper cover 311 also has a base 311B, a left post 311L, and a right post 311R with the same design, that is, the base 311B also forms a middle post M. The left post 311L of the upper cover 311 abuts against the left post 312L of the lower cover 312, the right post 311R of the upper cover 311 abuts against the right post 312R of the lower cover 312, and the middle post M of the upper cover 311 abuts against the middle post M of the lower cover 312, so that the upper cover 311 and the lower cover 312 can be stacked up and down. As Figure 3D shown, corresponding to the structure of the lower cover 312, the upper cover 311 also has a third winding post C3 and a fourth winding post C4. Similar to the design of the lower cover 312, the third winding post C3 and the fourth winding post C4 are arranged at intervals in the length direction LD, and the third winding post C3 and the fourth winding post C4 are offset from each other in the width direction WD. Thereby, the first winding post C1 of the lower cover 312 can be aligned with the third winding post C3 of the upper cover 311, and the second winding post C2 of the lower cover 312 can be aligned with the fourth winding post C4 of the upper cover 311. In this embodiment, when the upper cover 311 and the lower cover 312 are stacked, there is a gap d 13 between the first winding post C1 and the third winding post C3, and there is a gap d 24, but the present utility model is not limited thereto. That is, the first winding post C1 can also be in contact with the third winding post C3, and the second winding post C2 can also be in contact with the fourth winding post C4.

[0072] Fourth Embodiment:

[0073] Please refer to FIGS. 4A to 4D, showing a magnetic component 400 of the fourth embodiment of the present utility model. FIGS. 4A and 4C illustrate perspective views of the magnetic component 400, Figure 4B showing corresponding Figure 4A top views, Figure 4D showing corresponding Figure 4C top views, wherein in order to clearly show the internal configuration, the upper cover 411 of the magnetic core of the magnetic component 400 is omitted in FIGS. 4A and 4B.

[0074] The magnetic component 400 of this embodiment is, for example, a transformer or an iron core inductor or a combination thereof. The magnetic component 400 includes a magnetic core, a first winding W1, and a second winding W2. The magnetic core includes an upper cover 411 and a lower cover 412. The lower cover 412 has a first winding post C1 and a second winding post C2, such that the first winding W1 is wound around the first winding post C1, and the second winding W2 is wound around the second winding post C2. The first winding W1 and the second winding W2 can each be a combination of a primary coil and a secondary coil, and the number of the primary coil and the secondary coil can be determined according to the actual application requirements, and the present utility model is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 are, for example, both cylindrical, but the present utility model is not limited thereto. The shapes of the first winding post C1 and the second winding post C2 can also both be prismatic; or, the shapes of the first winding post C1 and the second winding post C2 can also be different, for example, one is cylindrical and the other is prismatic.

[0075] As Figure 4B shown, the first winding post C1 and the second winding post C2 are spaced apart along the length direction LD of the magnetic component 400, and the first winding post C1 and the second winding post C2 are offset from each other along the width direction WD of the magnetic component 400, wherein the width direction WD (parallel to the coordinate X axis in the figure) is perpendicular to the length direction LD (parallel to the coordinate Y axis in the figure). Specifically, the center O C1 of the first winding post C1 and the center O C2 of the second winding post C2 have a distance d L in the length direction LD, and the center O C1 of the first winding post C1 and the center O C2 of the second winding post C2 have a distance d W, that is, the first winding column C1 and the second winding column C2 are arranged diagonally in the magnetic component 400, which is different from the horizontal arrangement adopted in the prior art. Thus, in a situation where the heat dissipation wind direction is preset to blow along the length direction LD, through this diagonal arrangement, the first winding W1 and the second winding W2 in the magnetic component 400, as well as the first winding column C1 and the second winding column C2, can all receive the wind flow, thereby improving the problem of uneven heat dissipation.

[0076] Further describing this embodiment, the lower cover body 412 has a base 412B and two side columns. The first winding column C1 and the second winding column C2 are formed on the base 412B. In this embodiment, these two side columns are the left side column 412L and the right side column 412R. The left side column 412L and the right side column 412R are formed at both ends of the base 412B, and the first winding column C1 and the second winding column C2 are located between the left side column 412L and the right side column 412R. The first winding column C1 is adjacent to the left side column 412L, and the second winding column C2 is adjacent to the right side column 412R. Corresponding to the diagonal arrangement of the first winding column C1 and the second winding column C2 in the magnetic component 400, the left side column 412L and the right side column 412R are also arranged offset from each other along the width direction WD. As Figure 4B shown, the first winding column C1 completely projects and overlaps with the left side column 412L in the length direction LD, and the second winding column C2 completely projects and overlaps with the right side column 412R in the length direction LD.

[0077] The lower cover body 412 further has two outward expansion structures. In this embodiment, these two outward expansion structures are the front outward expansion structure E1 and the rear outward expansion structure E2. The front outward expansion structure E1 and the rear outward expansion structure E2 are formed on the base 412B protruding along the oblique straight direction ID, where the oblique straight direction ID is inclined to the length direction LD and the width direction WD (that is, parallel to an oblique line on the X-Y coordinate plane). As Figure 4B shown, the front outward expansion structure E1 has an arc-shaped side wall A1, and the rear outward expansion structure E2 has an arc-shaped side wall A2, but it is not limited to this. The side wall shapes of the front outward expansion structure E1 and the rear outward expansion structure E2 can also be different and are not limited to having arc-shaped side walls. For example, the front outward expansion structure E1 has a multi-sided wall structure, and the rear outward expansion structure E2 can have an arc-shaped side wall A2; or the front outward expansion structure E1 has an arc-shaped side wall A1, and the rear outward expansion structure E2 can have a multi-sided wall structure, etc.

[0078] As Figure 4A shown, in the height direction HD of the magnetic component 400, the height h 412L of the left side column 412L 412R is equal to the height h of the right side column 412R, and the heights of these two side columns are greater than the height h 412B of the base 412B, the height h E1 of the front outward expansion structure E1 and the height h of the rear outward expansion structure E2E2 is equal to the height h of the base 412B 412B , that is, the height h of the front outward expansion structure E1 E1 and the height h of the rear outward expansion structure E2 E2 is less than the height h of the left column 412L 412L and the height h of the right column 412R 412R , wherein the height direction HD (parallel to the coordinate Z axis in the figure) is perpendicular to the length direction LD and the width direction WD. The design of the outward expansion structure can increase the cross-sectional area of the magnetic flux passing through the center of the magnetic element 400 through the front outward expansion structure E1 and the rear outward expansion structure E2, thereby reducing the magnetic flux density and further reducing the core loss of the magnetic core.

[0079] As Figure 4C shown, corresponding to the structure of the lower cover 412, the upper cover 411 also has a base 411B, a left column 411L, and a right column 411R with the same design, that is, the base 411B also forms a front outward expansion structure E1 and a rear outward expansion structure E2. The left column 411L of the upper cover 411 abuts against the left column 412L of the lower cover 412, and the right column 411R of the upper cover 411 abuts against the right column 412R of the lower cover 412, so that the upper cover 411 and the lower cover 412 can be stacked up and down. When the upper cover 411 and the lower cover 412 are stacked up and down, the front outward expansion structure E1 of the upper cover 411 and the front outward expansion structure E1 of the lower cover 412 can be longitudinally aligned, and the rear outward expansion structure E2 of the upper cover 411 and the rear outward expansion structure E2 of the lower cover 412 can be longitudinally aligned.

[0080] As Figure 4D shown, corresponding to the structure of the lower cover 412, the upper cover 411 also has a third winding column C3 and a fourth winding column C4. Similar to the design of the lower cover 412, the third winding column C3 and the fourth winding column C4 are arranged at intervals along the length direction LD, and the third winding column C3 and the fourth winding column C4 are offset from each other along the width direction WD. Thereby, the first winding column C1 of the lower cover 412 can be aligned with the third winding column C3 of the upper cover 411, and the second winding column C2 of the lower cover 412 can be aligned with the fourth winding column C4 of the upper cover 411. In this embodiment, when the upper cover 411 and the lower cover 412 are stacked, there is a gap d between the first winding column C1 and the third winding column C3 13 , and there is a gap d between the second winding column C2 and the fourth winding column C4 24 , but the present invention is not limited thereto. That is, the first winding column C1 may also abut against the third winding column C3, and the second winding column C2 may also abut against the fourth winding column C4.

[0081] It should be noted that the lower cover described in each of the above embodiments of the present utility model is not limited to being assembled with the upper cover described in the same embodiment. By designing the dimensions and alignment of the left column and right column of the upper cover and the left column and right column of the lower cover to match, the upper cover and the lower cover of each embodiment can be elastically assembled.

[0082] As can be seen from the present utility model, in the magnetic elements of the above embodiments, the combination of the first winding and the first winding column in the magnetic core and the combination of the second winding and the second winding column are arranged in an offset configuration, so that in a situation of a preset heat dissipation air flow direction, each combination of the windings and the winding columns in the magnetic element can receive the air flow to improve the problem of uneven heat dissipation. Specifically, as the offset degree between the first winding column C1 and the second winding column C2 in the embodiment increases, that is, corresponding to the case where the value of the distance d W is higher, the windings and winding columns farther away from the heat dissipation air source can receive more air flow, and the overall heat dissipation effect of the magnetic element is also better.

[0083] In summary, although the present utility model has been described above with embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs, without departing from the protection scope of the present utility model, the solutions obtained by simple transformation all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to that defined by the appended patent application scope.
