Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically to an amorphous strip wound iron core disc. Background Technology

[0002] A reactor is a device that uses electromagnetic induction to achieve filtering and reactive power compensation. An iron-core reactor is a reactor in which an iron core is inserted into a energized coil to increase inductance. The iron core is typically composed of several iron core discs and a yoke joined together.

[0016] In summary, this utility model has at least one of the following advantages:

[0017] (1) A single iron-based amorphous strip is rolled into a multi-layered cylindrical shape to form an amorphous iron core with a circular cross-section. Under the premise of improving space utilization and induction intensity, it has fewer components, thereby simplifying the manufacturing and assembly steps and reducing the difficulty of operation, thus improving production efficiency. At the same time, since a single amorphous iron core is composed of a single iron-based amorphous strip, the problem of a large number of magnetic gaps generated at the splicing position of multiple components is avoided, thereby reducing the problem of magnetic flux leakage.

[0018] (2) The resin layer is used to coat the amorphous iron core, thereby achieving insulation, protection and shaping of the amorphous iron core; the resin layer and the amorphous iron core are integrally formed by casting, which has structural stability and is easy and quick to process and manufacture.

[0019] (3) When the cooling fluid flows through the fluid channel, it carries away the heat in the resin layer, thereby cooling the resin layer and the amorphous iron core and ensuring safe operation.

[0020] (4) The top plate is provided with a first channel group for achieving flow diversion, and the bottom plate is provided with a second channel group for achieving flow convergence. Thus, a single utility model only needs to install one air inlet pipe and one exhaust pipe to connect multiple fluid channels, thereby achieving the effect of saving internal space of the reactor.

[0021] (5) The top plate includes a first plate and a second plate that are interlocked and fixed together, and the bottom plate includes a third plate and a fourth plate that are interlocked and fixed together, so as to facilitate the processing and forming of the first and second annular holes; the second plate and the resin layer are integrally fixedly connected by casting and the tension is improved by the first tie member in the shape of an I-beam and the reinforcing fiber to prevent them from separating; the third plate and the resin layer are integrally fixedly connected by casting and the tension is improved by the second tie member in the shape of an I-beam and the reinforcing fiber to prevent them from separating.

[0022] (6) The fluid channel is formed by tube body. Compared with the traditional drilling and forming technology, this utility model will not produce scratch cracks on the inner wall of the fluid channel, thereby improving the structural strength of the resin layer, so as to stably cover and limit the iron-based amorphous ribbon that is curled and has a tendency to spring open.

[0042] Based on the above-described structural features of this application, the implementation methods of this application will be further described as follows:

[0043] Reference Figures 1-2 This embodiment provides an amorphous ribbon wound core disc, including an amorphous iron core 1 and a resin layer 2 covering the outer surface of the amorphous iron core 1; the amorphous iron core 1 is a single iron-based amorphous ribbon 11 wound into a multi-layered cylindrical shape. The iron-based amorphous ribbon 11 has the characteristics of high saturation magnetic induction and low loss, which can greatly reduce the weight of the equipment, reduce its size, and improve efficiency. The amorphous iron core 1 has a multi-layered cylindrical structure, thus having the highest possible density, thereby making the amorphous iron core 1 and the entire reactor have the smallest possible volume.

[0044] Reference Figures 1-2 The resin layer 2 is cylindrical in shape, thus adaptably coating the amorphous iron core 1.

[0045] Reference Figures 3-4 The resin layer 2 contains several fluid channels 21 arranged in a circular array with equal spacing and angles around the axis of the amorphous iron core 1. The fluid channels 21 are arranged along the axial direction of the resin layer 2. The top opening of each fluid channel 21 is located on the top surface of the resin layer 2, and the bottom opening is located on the bottom surface of the resin layer 2, facilitating assembly. Cooling fluid flows through the fluid channels 21, carrying away heat from the resin layer 2 and thus achieving controlled cooling of the amorphous iron core 1.

[0046] Reference Figures 3-4 The number of fluid channels 21 is no less than four, so that they are evenly distributed on the side wall of the resin layer 2 to achieve uniform heat dissipation.

[0047] The cooling fluid is air or an inert gas (such as nitrogen, helium, neon, argon, krypton, etc.), thereby improving the safety of this invention in use.

[0048] Reference Figures 3-4 The top surface of the resin layer 2 is provided with a top plate 3, and the top plate 3 is provided with a first channel group for injecting cooling fluid into the fluid channels 21 respectively. The inlet end of the first channel group is connected to an air inlet pipe via an air nozzle.

[0049] Reference Figures 3-4 A base plate 4 is provided on the bottom surface of the resin layer 2. The base plate 4 contains a second channel group for converging the cooling fluid discharged from the fluid channel 21. The outlet section of the second channel group is connected to an exhaust pipe via a nozzle. The exhaust pipe is connected to a gas storage tank, which is connected to an air pump via an air inlet pipe. The air pump is connected to an air inlet pipe. The gas storage tank and air pump are placed on a workbench. The air pump pressurizes the cooling fluid from the gas storage tank into the fluid channel 21. The cooling fluid carries the heat from the resin layer 2 and flows back into the gas storage tank, thereby cooling the reactor. The gas storage tank contains a cooling structure, such as a semiconductor refrigerator, which allows the cooling fluid to be injected into the fluid channel 21 at a low temperature, enhancing the cooling effect and preventing the resin layer 2, second plate 302, third plate 401, first bolt, and second bolt from softening due to heat, thus improving the connection strength.

[0050] Reference Figures 3-4 The top plate 3 is in the shape of a ring that fits the top surface of the resin layer 2; the bottom plate 4 is in the shape of a ring that fits the bottom surface of the resin layer 2.

[0051] Reference Figure 4 and Figure 5 The top plate 3 has a first annular hole 32, and a vertical air inlet 31 on its top surface. The bottom end of the air inlet 31 is perpendicularly connected to the first annular hole 32, and the air inlet 31 is a through hole. The bottom surface of the top plate 3 has several vertical first connecting holes 33, the top ends of which are connected to the first annular hole 32. The first connecting holes 33 are through holes, and the first connecting holes 33 are coaxially arranged and connected to the top end of the fluid channel 21. The air inlet pipe is connected to the top end of the air inlet 31 through an air nozzle. The first annular hole 32 diverts the cooling fluid in a single air inlet pipe into several streams of cooling fluid equal to the number of fluid channels 21, and injects them into the fluid channels 21 respectively, thereby achieving gas diversion and avoiding the problem of occupying too much internal space of the reactor due to installing too many air nozzles and air inlet pipes (compared to connecting independent air nozzles and air inlet pipes to each fluid channel 21).

[0052] Reference Figure 5 and Figure 6The top plate 3 includes a first plate 301 and a second plate 302 that are interlocked and fixed together. An air inlet 31 is located within the first plate 301, and a first connecting hole 33 is located within the second plate 302. The first annular hole 32 includes a first annular groove and a second annular groove that are adapted to and interlocked with each other. The first annular groove is located on the bottom surface of the first plate 301, and the second annular groove is located on the top surface of the second plate 302. The first plate 301 and the second plate 302 are independently injection molded and then assembled, thereby reducing the complexity of the mold structure and improving the ease and efficiency of production.

[0053] Reference Figure 4 and Figure 7 The base plate 4 has a second annular hole 42 inside, and a vertical exhaust hole 41 on the bottom surface of the base plate 4. The top of the exhaust hole 41 is vertically connected to the second annular hole 42, and the exhaust hole 41 is a through hole. The top surface of the base plate 4 has several vertical second connecting holes 43. The bottom of the second connecting holes 43 is connected to the second annular hole 42, and the second connecting holes 43 are through holes. The second connecting holes 43 are coaxially arranged and connected to the bottom of the fluid channel 21. The second annular hole 42 merges and guides several streams of cooling fluid in the fluid channel 21 to the exhaust hole 41 and the exhaust pipe, thereby realizing the convergence of gas and avoiding the problem of occupying too much internal space of the reactor due to the installation of too many air nozzles and exhaust pipes (compared to each fluid channel 21 being connected to an independent air nozzle and exhaust pipe).

[0054] Reference Figure 7 and Figure 8 The base plate 4 includes a third plate 401 and a fourth plate 402 that are interlocked and fixed together. A vent 41 is located within the fourth plate 402, and a second connecting hole 43 is located within the third plate 401. The second annular hole 42 includes a third annular groove and a fourth annular groove that are adapted to and interlocked together. The third annular groove is located on the bottom surface of the third plate 401, and the fourth annular groove is located on the top surface of the fourth plate 402. The third plate 401 and the fourth plate 402 are independently injection molded and then assembled, thereby reducing the complexity of the mold structure and improving the ease and efficiency of production and processing.

[0055] Reference Figure 9The fluid channel 21 has a tube 22 on its inner wall. Both ends of the tube 22 extend from the fluid channel 21 and are inserted into the first connecting hole 33 of the second plate 302 and the second connecting hole 43 of the third plate 401, respectively. Before casting the resin layer 2, the two ends of the tube 22 are inserted into the first connecting hole 33 and the second connecting hole 43, respectively, so that the outer wall of the tube 22, the inner wall of the molding mold, the end face of the second plate 302, the end face of the third plate 401, and the outer wall of the amorphous iron core 1 form a closed casting cavity. Resin is then poured into the casting cavity to obtain the resin layer 2. The tube 22 is used to form the fluid channel 21, preventing the fluid channel 21 from being filled and blocked by resin. At the same time, the tube 22 prevents resin from flowing into the first connecting hole 33 and the second connecting hole 43, ensuring the connectivity of the first and second channel groups.

[0056] The outer walls at both ends of the tube 22 are respectively attached to the inner walls of the first connecting hole and the second connecting hole; the outer wall in the middle of the tube 22 is attached to the inner wall of the fluid channel 21.

[0057] The tube body 22 is made of a non-ferrous, non-magnetic material (such as resin) to avoid heating due to magnetic induction.

[0058] Reference Figure 3 , Figure 6 and Figure 8 Both the second plate 302 and the third plate 401 are made of resin material, which facilitates their connection with the resin layer 2. The second plate 302 and the resin layer 2 are fixedly connected by integral casting.

[0059] Reference Figure 6 and Figure 8 The first plate 301 and the second plate 302 are connected by a first bolt, and the third plate 401 and the fourth plate 402 are connected by a second bolt. The stud of the first bolt is screwed into the second plate 302, and the stud of the second bolt is screwed into the third plate 401. The bottom end of the first bolt is located above the top end of the amorphous iron core 1. The bottom end of the second bolt is located above the top end of the amorphous iron core 1. Both the first and second bolts are made of non-ferrous, non-magnetic materials (such as resin, aluminum alloy, titanium alloy, etc.) to avoid heating due to magnetic induction (the second plate 302 has a screw hole that fits and engages with the first bolt, and the third plate 401 has a screw hole that fits and engages with the second bolt; the threads of the screw holes are more prone to deformation due to heat, causing the first and second bolts to loosen).

[0060] The molding template includes two upright side molds, which are arc-shaped and can be joined together to form a cylindrical cavity.

[0061] The manufacturing steps of this utility model are as follows: ① First, injection molding of the first plate 301, the second plate 302, the third plate 401, and the fourth plate 402 is performed; ② The second plate 302 and the third plate 401 are respectively snapped into the upper and lower ends of the left mold cavity, so that the left half of the second plate 302 is snapped into the cavity and the right half is suspended, and the left half of the third plate 401 is snapped into the cavity and the right half is suspended; ③ The first connecting hole 33 and the second connecting hole 43, which are located in the left mold cavity and correspond to each other, are connected by a tube 22, that is, the two ends of the tube 22 are respectively inserted into the first connecting hole 301. 3. Place the amorphous iron core 1 into the second connecting hole 43; ④ Place the left half of the amorphous iron core 1 into the left cavity (for example, use a sling to support the amorphous iron core 1); ⑤ Connect the remaining and corresponding first connecting holes 33 and second connecting holes 43 of the second plate 302 and the third plate 401 with a tube 22, that is, insert the two ends of the tube 22 into the first connecting hole 33 and the second connecting hole 43 respectively; ⑥ Close the mold and inject resin into the cavity; ⑦ Cool and open the mold; ⑧ Install the first plate 301 on the upper surface of the second plate 302 and install the fourth plate 402 on the lower surface of the third plate 401.

[0062] Reference Figure 10 A number of first connecting members 5 are provided between the second plate 302 and the resin layer 2, and a number of second connecting members 6 are provided between the third plate 401 and the resin layer 2, thereby addressing the problem of insufficient tension between the second plate 302, the resin layer 2, and the third plate 401.

[0063] Reference Figure 10 Both the first tie member 5 and the second tie member 6 are H-shaped linear structures. The upper part of the first tie member 5 is fixedly installed inside the second plate 302 (during the injection molding of the second plate 302, the first tie member 5 is partially embedded and fixedly connected to the second plate 302). The lower part of the second tie member 6 is fixedly installed inside the third plate 401 (during the injection molding of the third plate 401, the second tie member 6 is partially embedded and fixedly connected to the third plate 401). The lower part of the first tie member 5 and the upper part of the second tie member 6 are fixedly installed in the resin layer 2 by casting, thereby increasing the tensile force between the second plate 302, the resin layer 2, and the third plate 401 and preventing them from separating.

[0064] The bottom surface of the second plate 302 is provided with several vertically oriented burrs. The bottom ends of the burrs are cast and fixed within the resin layer 2, thereby increasing the bonding strength between the second plate 302 and the resin layer 2 and preventing detachment. The top surface of the third plate 401 is also provided with several vertically oriented burrs. The top ends of the burrs are cast and fixed within the resin layer 2, thereby increasing the bonding strength between the third plate 401 and the resin layer 2 and preventing detachment. The burrs are reinforcing fibers, evenly distributed on the bottom surface of the second plate 302 and the top surface of the third plate 401.

[0065] The contact surfaces of the first plate 301 and the second plate 302 are provided with sealing strips or are ultrasonically welded to achieve a seal; the contact surfaces of the third plate 401 and the fourth plate 402 are provided with sealing strips or are ultrasonically welded to prevent air leakage from the first annular hole 32 and the second annular hole 42.

[0066] Each of the present invention contains multiple amorphous iron cores 1, which are coaxially arranged (supported and fixed by resin layer 2). Air gap pads are provided between adjacent amorphous iron cores 1, and the air gap pads are covered, supported and fixed by resin layer 2.

[0067] This invention features a simple structure and reliable function. A single iron-based amorphous strip 11 is rolled into a multi-layered cylindrical shape to form an amorphous iron core 1 with a circular cross-section. While improving space utilization and induction intensity, it has a smaller number of components, thereby simplifying manufacturing and assembly steps, reducing operational difficulty, and improving production efficiency. At the same time, since a single amorphous iron core 1 is composed of a single iron-based amorphous strip 11, it avoids the problem of a large number of magnetic gaps at the splicing positions of multiple components, thereby reducing the problem of magnetic flux leakage.
