Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0032] As shown in the drawings, Figures 1-5 A novel magnetic component structure, comprising a magnetic component body 1, the structure further comprises:
[0033] A U-shaped liquid cooling plate 2, two side guards 3 are arranged on both sides of the U-shaped liquid cooling plate 2, the U-shaped liquid cooling plate 2 and the two side guards 3 form a containing space, and the magnetic component body 1 is sleeved in the containing space;
[0034] An upper liquid tank 4 and a lower liquid tank 5, the upper liquid tank 4 and the lower liquid tank 5 are connected through pipelines, and the upper liquid tank 4 and the lower liquid tank 5 are respectively installed on the top and bottom of the U-shaped liquid cooling plate 2, and the upper liquid tank 4 and the lower liquid tank 5 provide cooling liquid for the U-shaped liquid cooling plate 2.
[0035] In one case of the embodiment, cooling pumps are arranged in the upper liquid tank 4 and the lower liquid tank 5, the cooling liquid output by the upper liquid tank 4 flows in the U-shaped liquid cooling plate 2 and then enters the lower liquid tank 5, is cooled by the cooling pump and is delivered into the upper liquid tank 4, through such circulation, the temperature of the cooling liquid can cool and dissipate heat for the magnetic component body 1.
[0036] In actual application, the U-shaped liquid cooling plate 2 and the two side guards 3 are sleeved outside the magnetic component body 1 to replace the shell in the prior art, and directly contact the magnetic component body 1 through the U-shaped liquid cooling plate 2 to dissipate heat, so that the heat dissipation effect is improved, and the volume of the magnetic component is reduced, so that the magnetic component can adapt to small installation space.
[0037] The U-shaped liquid cooling plate 2 covers the top, bottom and one side of the magnetic component body 1, compared with the prior art in which the liquid cooling plate is arranged on only one side, the contact area between the U-shaped liquid cooling plate 2 and the magnetic component body 1 is larger, so that the heat dissipation effect of the magnetic component body 1 is further improved.
[0038] Further, a plurality of main flow channels 21 are arranged in the U-shaped liquid cooling plate 2, the main flow channels 21 are also U-shaped, and the two ends of the main flow channels 21 are connected with the upper liquid tank 4 and the lower liquid tank 5 respectively.
[0039] In actual application, the cooling liquid flows through the main flow channel 21. Since the main flow channel 21 is a straight flow channel, the flow rate of the cooling liquid can be increased, the cooling liquid can be circulated quickly, and the effect of rapid cooling and heat dissipation can be achieved, thereby improving the heat dissipation effect on the magnetic component body 1.
[0040] Further, a plurality of sub-flow channels 22 are arranged in the U-shaped liquid cooling plate 2, and the two ends of each sub-flow channel 22 are communicated with the main flow channel 21 through a branch flow channel 221 and a converging flow channel 222.
[0041] In actual application, the plurality of sub-flow channels 22 and the plurality of main flow channels 21 can expand the area of the U-shaped liquid cooling plate 2 through which the cooling liquid flows, so that most of the area of the U-shaped liquid cooling plate 2 can cool and dissipate heat for the magnetic component body 1, thereby improving the heat dissipation effect on the magnetic component body 1.
[0042] Further, a plurality of cavities 23 and a plurality of movable grooves 24 are arranged in the U-shaped liquid cooling plate 2. The cavity 23 is located between the main flow channel 21 and the sub-flow channel 22. The air bag 7 is installed in the cavity 23. The T-shaped plate 8 is slidably installed in the cavity 23. The T-shaped plate 8 penetrates the cavity 23 and extends into the movable groove 24. The elastic member 9 is installed in the movable groove 24 and abuts against the T-shaped plate 8. The through hole 81 is arranged on the T-shaped plate 8.
[0043] In one case of the embodiment, the elastic member 9 can be a spring or other elastic component. The air bag 7 expands when heated and slowly contracts when the temperature slowly decreases.
[0044] In actual application, when the temperature of the magnetic component body 1 is relatively high, the air bag 7 slowly expands, thereby pushing the T-shaped plate 8 to move towards the movable groove 24 and compressing the elastic member 9. At this time, the through hole 81 on the T-shaped plate 8 slowly comes out of the cavity 23 and slowly coincides with the branch flow channel 221. In this way, the cooling liquid can enter the sub-flow channel 22 through the branch flow channel 221 and the through hole 81, thereby expanding the area of the U-shaped liquid cooling plate 2 through which the cooling liquid flows and improving the heat dissipation effect. When the temperature of the magnetic component body 1 slowly decreases, the air bag 7 also slowly contracts, and the elastic member 9 rebounds, thereby making the T-shaped plate 8 move towards the cavity 23. The through hole 81 slowly retracts into the cavity 23, and the T-shaped plate 8 blocks the branch flow channel 221, so that the cooling liquid can only flow through the main flow channel 21.
[0045] Further, a plurality of U-shaped heat dissipation fins 6 are arranged outside the U-shaped liquid cooling plate 2.
[0046] In actual application, the fins 6 can assist the U-shaped liquid cooling plate 2 to cool the magnetic component body 1, thereby improving the heat dissipation effect; in addition, the upper and lower surfaces of the fins 6 are flush with the upper liquid tank 4 and the lower liquid tank 5, so that high-efficiency heat dissipation can be maintained while ensuring stable installation of the magnetic component.

[0048] The transformer magnetic core 11 has a plurality of flat coils 12 installed therein, the flat coils 12 are sleeved outside the central column in the transformer magnetic core 11, the flat coils 12 are sleeved with support plates 13, and the transformer magnetic core 11 further has a plurality of primary coils 18 installed therein, the primary coils 18 are located between the two support plates 13.
[0049] The inductor magnetic core 15 has an inductor coil 16 installed therein, the inductor coil 16 is a multi-layer turn winding structure, the inductor coil 16 is sleeved outside the central column in the inductor magnetic core 15, and the inductor coil 16 and the plurality of flat coils 12 are connected by the connecting piece 17 through spot welding process.
[0050] The transformer magnetic core 11 and the inductor magnetic core 15 are connected together, and the transformer magnetic core 11 and the inductor magnetic core 15 are sleeved in the accommodating space formed by the U-shaped liquid cooling plate 2 and the two side guard plates 3.
[0051] In one case of the embodiment, the flat coils 12 and the inductor coil 16 can both be copper bars, wherein the inductor coil 16 is formed by bending the copper bar into a multi-turn winding.
[0052] In actual application, the inductor coil 16 has a vertical winding structure, has the characteristics of small inductance structure and large current density; the flat coils 12 and the inductor coil 16 are respectively a flat structure and a multi-turn winding structure formed by bending a copper bar, which can effectively improve the winding space of the magnetic component and the packaging size of the magnetic component, i.e., the magnetic component has a smaller volume, at the same time, the flat coils 12 and the inductor coil 16 have larger cross-sectional areas, thereby improving the overload current capacity of the magnetic component; the flat coils 12 adopt flat winding to increase the heat dissipation area, have good heat conduction, and improve the heat dissipation effect; the connecting piece 17 between the flat coils 12 and the inductor coil 16 adopts spot welding process, thereby ensuring the tensile strength and meeting the large current.
[0053] Further, the transformer magnetic core 11 is provided with an inner recess 14.
[0054] In actual application, the inner recess 14 can increase the area of the side surface of the transformer magnetic core 11, thereby improving the heat dissipation performance of the whole magnetic component and being beneficial to prolonging the service life of the magnetic component.
