[0021] In order to make the inventive purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the following described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] In the description of the present application, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there can be a component disposed therebetween.

[0023] The technical solutions of the present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The embodiment of the present application provides an inductor, which comprises a packaging assembly 1 and an inductor assembly 2. Through the arrangement of the packaging assembly 1, the inductor assembly 2 can be detachably assembled, which is beneficial to good maintenance and replacement of the inductor assembly 2. When the inductor assembly 2 is accidentally damaged, the packaging assembly 1 can still be reused, saving the actual use cost. In the packaging state, the working heat of the inductor assembly 2 can also be well discharged, maintaining the inductor assembly 2 in a good working temperature environment. At the same time, the overall structural stability is ensured during packaging, which is more in line with the actual use requirements.

[0025] Specifically, the packaging assembly 1 comprises a packaging shell 11, a receiving groove 11-1 is formed in the inner side of the packaging shell 11, a liquid storage groove 11-3 is formed in the inner part of the packaging shell 11, a heat dissipation piece 12 is arranged on the packaging shell 11, a support piece 13 is arranged on the inner side of the heat dissipation piece 12, and the support piece 13 comprises a fixing seat 13-1 located in the receiving groove 11-1, an auxiliary frame 13-2 is fixedly connected to the outer circle of the fixing seat 13-1, a pressing rod 13-3 is rotatably connected to the auxiliary frame 13-2, and a fastening piece 14 is arranged on the packaging shell 11.

[0026] Through the arrangement of the heat dissipation piece 12, the working heat of the inductor assembly 2 can be well discharged in the packaging state, ensuring the stability of the inductor assembly 2.

[0027] Through the arrangement of the support piece 13, the inductor assembly 2 can be stably pressed from the inside, ensuring the overall structural stability.

[0028] Through the setting of the fastener 14, the two packaging shells 11 can be locked to ensure the installation stability of the packaging shell 11 and to well package the inductor assembly 2.

[0029] Specifically, the inductor assembly 2 is arranged in the packaging shell 11 and includes a magnetic core 21 arranged in the receiving groove 11-1 and a winding 22 wound on the magnetic core 21.

[0030] The magnetic core 21 is composed of laminated silicon steel sheets, has the advantages of high magnetic permeability, low loss, precise air gap control, and high mechanical strength, and in the processing process, annular blanking, lamination, adhesive fixing, heat treatment, and spraying strengthening are adopted.

[0031] In the lamination process, in order to control the air gap in the magnetic circuit, an insulating coating can be placed between the laminations. The insulating coating generally adopts special insulating paint, which is applied on the surface of the magnetic core by spraying or dipping. It can not only play an insulating role, but also reduce the eddy current loss. The working principle and the like of this part are prior art, and those skilled in the art can clearly know it, which will not be described here.

[0032] The winding 22 is uniformly wound on the magnetic core 21 by an annular winding machine. In actual use, the winding 22 has direct current resistance (DCR) and alternating current resistance (ACR) in itself. In a direct current scenario, when current passes through the wire, Joule loss is directly generated, and heat comes from the winding 22. In an alternating current scenario, the skin effect and proximity effect under high frequency will increase the alternating current resistance of the wire, resulting in additional loss and aggravating the heating of the winding 22. No matter how the working frequency is, as long as current passes through, the winding 22 loss always exists, especially in a large current or low frequency scenario. In a low frequency, large current or direct current scenario, because the resistance loss always exists, the winding 22 is the main heating position.

[0033] Referring to Figures 2-6 Specifically, the heat dissipation member 12 includes a heat conduction plate 12-1 fixed in the liquid storage groove 11-3, an outer side of the heat conduction plate 12-1 is provided with a sealing plate 12-2, and a heat dissipation plate 12-21 is embedded on the sealing plate 12-2.

[0034] The heat conduction plate 12-1 is made of copper material and closely adheres to the outer periphery of the magnetic core 21.

[0035] The sealing plate 12-2 is provided with an O-shaped sealing ring at the edge, which is in interference fit with the inner wall of the liquid storage groove 11-3 to prevent leakage of silicone oil.

[0036] The liquid storage groove 11-3 is internally provided with an appropriate amount of silicone oil, which has excellent electrical insulation, chemical inertness, and hydrophobicity, and can absorb the heat transmitted by the heat conduction plate 12-1.

[0037] The heat dissipation plate 12-21 is a porous aluminum substrate, and a large number of small holes are formed on the outer side of the heat dissipation plate 12-21, so that the surface area is effectively increased, and the heat dissipation efficiency is improved.

[0038] The fixed seat 13-1 is fixed at one end of the heat conduction plate 12-1, and the auxiliary frame 13-2 is arranged in a circular array on the fixed seat 13-1.

[0039] The auxiliary frame 13-2 is sleeved with a torsion spring 13-21, one end of the torsion spring 13-21 is fixed to the auxiliary frame 13-2, and the other end of the torsion spring 13-21 is fixed to the pressing rod 13-3.

[0040] Through the setting of the torsion spring 13-21, torsion can be provided for the pressing rod 13-3, and under the action of no external force, the pressing rod 13-3 is prevented from rotating and opening at will.

[0041] The end of the pressing rod 13-3 away from the auxiliary frame 13-2 is embedded with an anti-skid head 13-31.

[0042] Through the setting of the anti-skid head 13-31, the contact friction with the inner ring of the magnetic core 21 can be increased in the assembled state, and the overall stability of the structure is improved.

[0043] The anti-skid head 13-31 is made of rubber material, so as to avoid damaging the surface insulation coating of the laminated sheet of the magnetic core 21.

[0044] In the production of the magnetic core 21, in order to ensure the overall stability of the magnetic core 21, a plastic fixing frame is arranged on the outer periphery of the magnetic core 21, the plastic fixing frame is bonded to the edge of the laminated sheet of the magnetic core 21 by high-temperature resistant glue, direct contact with the laminated sheet is avoided, and in this state, the anti-skid head 13-31 will be in contact and pressed with the plastic fixing frame, so as to avoid affecting the air gap of the magnetic core 21 under pressure.

[0045] The fastener 14 is provided in two numbers and symmetrically arranged on both sides of the packaging shell 11.

[0046] The fastener 14 comprises a positioning seat 14-1 fixed to the packaging shell 11, a positioning rod 14-2 is arranged in the positioning seat 14-1, and screw threads 14-3 are formed on the top and bottom of the outer ring of the positioning rod 14-2.

[0047] The positioning rod 14-2 is composed of an internal hexagonal head, a thick rod and a thin rod, wherein the internal hexagonal head, the thick rod and the thin rod are fixedly connected in sequence from top to bottom, the screw threads 14-3 are provided in two numbers and arranged on the thick rod and the thin rod respectively, the thick rod is threadedly connected with the positioning seat 14-1 in cooperation with the screw threads 14-3, and the thin rod is connectable with an externally arranged mounting base in cooperation with the screw threads 14-3.

[0048] The bottom of the packaging shell 11 is fixed with a supporting leg 11-2, and a clamping groove 11-21 is formed in the bottom of the supporting leg 11-2.

[0049] Through the setting of the foot 11-2, the inductor assembly 2 bottom is exposed, and there is a space between the mounting surface, which is conducive to heat dissipation.

[0050] The winding 22 is fixed with an insulating sheet 22-1 at both ends, and a copper nut 22-11 is embedded in the insulating sheet 22-1.

[0051] The clamping groove 11-21 is in sliding fit with the insulating sheet 22-1, and the clamping groove 11-21 forms a receiving space for the insulating sheet 22-1, ensuring the compactness of the overall structure.

[0052] The pin on the winding 22 is fixed with the copper nut 22-11, which can ensure the circuit communication when the current is introduced, and the insulating sheet 22-1 exists to insulate and protect the winding 22 pin and the copper nut 22-11.

[0053] Referring to Figures 1-6 A processing method of an inductor, comprising the following steps: Step one: assemble the magnetic core 21 laminations: die cutting: use a precision progressive die or a composite die to form an annular silicon steel sheet (inner hole, outer diameter, thickness are processed synchronously) by a punch press; after die cutting, remove the edge burrs by a brush wheel or a sandpaper machine to avoid short circuit of the laminations or damage of the insulation layer caused by the burrs.

[0054] Adopt roll coating or spraying process to coat water-based insulating paint (such as polyester modified epoxy resin paint) on both sides of the silicon steel sheet, control the coating thickness at 3 μm, ensure the insulation resistance between the laminations ≥10 MΩ, and the drying condition is: 130℃ baking for 12 minutes to form a dense insulation layer, and at the same time avoid destroying the silicon steel magnetic crystal orientation at high temperature.

[0055] Stack the annular sheets in the "interlaced joint" mode (i.e. the joints of adjacent two layers are staggered by 180°), reduce the magnetic air gap, and improve the consistency of magnetic permeability; the stacking pressure is controlled at 8N / mm² (through a hydraulic machine or a servo press), to ensure the tightness of the laminations (lamination coefficient ≥95%), and avoid vibration noise.

[0056] After stacking, use epoxy resin glue to point and fix along the outer circumference of the annular, or use glass fiber tape to tie, to prevent displacement of the laminations during annealing.

[0057] Stress relief annealing: eliminate the mechanical stress in the cutting and stacking process, restore the magnetic properties of silicon steel (reduce iron loss and improve magnetic permeability), and apply a weak magnetic field during annealing to guide the magnetic domain orientation consistent with the annular magnetic circuit, further reduce the iron loss.

[0058] The whole is immersed in insulating varnish (such as 1032 melamine alkyd paint), and after drying, a moisture-proof and shock-proof protective layer is formed to improve the mechanical strength. The annular outer circumference can be wrapped with a magnetic shielding layer (such as permalloy foil) to reduce the influence of magnetic leakage, and the plastic fixing frame is used for outer circumference fixation to ensure the overall stability of the magnetic core 21.

[0059] After processing, detection is performed, including size precision detection, insulation performance detection, and magnetic performance detection.

[0060] The winding 22 is wound on the magnetic core 21: a magnetic powder tensioner or a servo tensioner is used, and the tension is set to 18% of the tensile strength of the wire to avoid wire deformation caused by excessive tension or loose winding caused by insufficient tension.

[0061] The wire passes through the hollow shaft through the magnetic core inner hole, and the winding arm rotates to complete the annular winding. Single-layer dense winding is suitable for small inductance and high-frequency scenarios, and the wire is tightly arranged without overlapping to reduce interlayer parasitic capacitance.

[0062] After winding, point and apply quick-drying epoxy resin glue to prevent lead loosening.

[0063] After forming, the winding 22 is subjected to electrical performance detection, including inductance test, direct current resistance detection, and turn-to-turn insulation voltage resistance, and mechanical performance detection, including winding tightness test and lead tension test.

[0064] The two ends of the winding 22 are crimped and fixed with copper nuts 22-11 to ensure the stability of the connection between the winding 22 pins and the copper nuts 22-11.

[0065] The copper nuts 22-11 and the two ends of the winding 22 are placed in an injection mold, and the insulating material is injected into the mold to cover the copper nuts 22-11 and the winding 22, forming a hard insulating sheet 22-1 to achieve the purpose of insulation protection.

[0066] During injection molding, the moving mold and the fixed mold of the injection molding machine are precisely aligned and closed through the guide mechanism to form a sealed cavity, and the copper nuts 22-11 and the winding 22 are accommodated; at the same time, granular plastic falls into the barrel from the hopper, and the screw rotates to transport the raw materials through the screw groove, and the external heating ring and screw shearing heat of the barrel melt the raw materials into uniform melt.

[0067] The melt is injected into the mold cavity at high pressure, and the filling process needs to be completed before the plastic cools down, and when the melt starts to cool and shrink, the screw maintains pressure (the holding pressure is 70% of the injection pressure) to continuously feed the cavity to prevent shrinkage and cavitation.

[0068] The mold internal cooling system (pipeline network) removes heat through circulating medium (water or oil) to gradually solidify the melt from the outside to the inside.

[0069] After cooling, the movable mold retreats with the injection molding machine moving plate, and the mold opens; the ejection mechanism pushes the product out of the movable mold, avoiding improper position of the ejector pin causing product deformation or white top.

[0070] Step two: lock the sealing plate 12-2 in the liquid storage tank 11-3, then pour silicone oil into the liquid storage tank 11-3.

[0071] Step three: move the packaging shell 11 close to the inductor assembly 2, and the support 13 is placed in the magnetic core 21. As the two packaging shells 11 move close to each other, the pressing rods 13-3 on the two fixing seats 13-1 will contact and press each other. The pressing rod 13-3 rotates on the auxiliary frame 13-2, and the torsional spring 13-21 is compressed until the pressing rod 13-3 stably presses the inner circle of the magnetic core 21, realizing reinforcement and support and improving the overall stability of the structure.

[0072] Step four: after the pressing rod 13-3 stably presses the magnetic core 21, the two packaging shells 11 are also in contact with each other. At this time, the positioning rod 14-2 is lowered to pass through the positioning seat 14-1, and the positioning rod 14-2 is rotated to stably connect with the screw thread 14-3 and the positioning seat 14-1, ensuring the stability of the installation between the two packaging shells 11.

[0073] In use, the insulating sheet 22-1 is placed in the clamping groove 11-21, and the positioning rod 14-2 is rotated to cooperate with the lower screw thread 14-3 and the mounting base to fix the overall installation stability of the structure. The external cable can realize circuit communication by stably connecting with the copper nut 22-11, and the heat generated by the winding 22 can be well dissipated by the cooperation of the heat-conducting plate 12-1, the silicone oil in the liquid storage tank 11-3, and the heat sink 12-21.

[0074] Reference Figures 4-6 , specifically, according to the actual use scene, the silicone oil in the liquid storage tank 11-3 can be replaced by a fluorinated liquid with better heat conduction efficiency at the same time.

[0075] As shown in the drawings Figure 5 , the sealing plate 12-2 is fixed with a protrusion on the side, and is fixed in the liquid storage tank 11-3 by sealing bolts, thereby ensuring the sealing property and preventing the medium in the liquid storage tank 11-3 from flowing out at will.

[0076] The packaging shell 11 is embedded with a liquid injection valve, which can store an appropriate amount of heat-conducting medium in the liquid storage tank 11-3 in the open state.

[0077] As shown in the drawings Figure 5 , one side of the foot 11-2 is fixed with a protruding rod, and the other side of the foot 11-2 is provided with a groove at the corresponding position. The groove and the protruding rod are in sliding cooperation. This design can effectively improve the accuracy of the butt joint of the two packaging shells 11 and better meet the actual use requirements.

[0078] The area of the heat-conducting plate 12-1 adhered to the outer periphery of the magnetic core 21 is not less than 80% of the side area of the magnetic core 21, and the filling rate of the silicon oil in the liquid storage tank 11-3 is 85%-90%, thereby ensuring efficient heat dissipation through the three-stage conduction path of the heat-conducting plate 12-1→the silicon oil→the heat-dissipating plate 12-21.

[0079] In actual application, in order to ensure the surface quality of the insulating sheet 22-1, deburring and polishing treatment are performed on the insulating sheet 22-1 after injection molding.

[0080] The above-described embodiments are merely used to illustrate the technical solutions of the present application, rather than limit the same; although the present application has been described in detail with reference to the foregoing embodiments, those ordinarily skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
