Description

Technical Field

[0001] This utility model relates to the field of magnetic core curing oven technology, specifically an amorphous magnetic core curing oven. Background Technology

[0002] Amorphous magnetic cores, also known as amorphous state magnetic cores or amorphous alloy magnetic cores, are magnetic cores made of materials containing amorphous metal alloys. Their most significant characteristic is the disordered arrangement of atoms, forming an amorphous structure. This structure endows amorphous magnetic cores with low coercive loss, high magnetic permeability, and high saturation magnetic flux density. The curing process is a crucial step in the manufacturing of amorphous magnetic cores, primarily aimed at enhancing their mechanical strength and stability. After winding and forming, amorphous magnetic cores typically require heat treatment (annealing). Annealed cores are relatively brittle and easily break under external forces, thus necessitating curing. During curing, the cores impregnated with a curing agent are placed in an oven for drying and curing.

[0003] In a published Chinese patent application (publication number CN118053667A), titled "A Multi-Layer Fixture for Sintering and Curing Magnetic Rings and a Method for Curing Magnetic Cores," this prior art utilizes a combination of water pipes, an inlet, and an outlet. Water pipes are distributed within a first and second placement plate. After the magnetic core is sintered, the fixture is removed, and a condensate solution is introduced into the inlet. The condensate solution flows through the water pipes within the first and second placement plates, and the outlet allows the heated condensate solution to exit. This heat exchange effect rapidly cools the magnetic core on top of the first and second placement plates, reducing cooling time. While this prior art can achieve the drying and curing of the magnetic core, it has certain limitations in practical implementation.

[0004] In its specific implementation, the existing technology involves placing the magnetic core in a slot on a placement plate, installing a water pipe inside the placement plate, and using the water flow inside the water pipe to cool the placement plate, thereby achieving cooling of the magnetic core. However, since the placement plate is mounted on the positioning column via a rotating column, the placement plate is not easy to disassemble, making it inconvenient to pick up or put down the magnetic core. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an amorphous magnetic core curing oven, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an amorphous magnetic core curing oven, comprising an oven body with a door rotatably mounted on it; the amorphous magnetic core curing oven further comprises a cooling component and multiple fixture plates, the cooling component comprising a conveying assembly and a support assembly, the support assembly comprising a first support box, a second support box, and multiple cooling elements, the first support box being fixedly mounted on one inner side wall of the oven body, the second support box being fixedly mounted on another inner side wall of the oven body, and the first support box being parallel to the second support box; each cooling element is arranged longitudinally in sequence, each cooling element comprising multiple square tubes, and the square tubes in the cooling element are arranged transversely in sequence; both ends of the square tubes are fixedly mounted to the first support box and the second support box respectively, and the square tubes are respectively connected to the first support box and the second support box; each fixture plate is placed above each cooling element; multiple fins are fixedly connected to the inner top wall of the square tube, and the lower surface of the fixture plate abuts against the upper surface of the square tube.

[0007] Optionally, the fixture plate is provided with multiple slots for placing magnetic cores.

[0008] Optionally, an inflow pipe is fixedly installed on the top wall of the first support box and the two are connected, and an outflow pipe is fixedly installed on the top wall of the second support box and the two are connected.

[0009] Optionally, the conveying assembly includes a cooling box, a conveying pump, and a cyclone cooler. The cooling box is fixedly installed on an outer side wall of the oven body, the conveying pump is fixedly installed on the cooling box, and the cyclone cooler is fixedly installed on an outer side wall of the cooling box.

[0010] Optionally, the cooling tank contains coolant, the medium inflow end of the delivery pump is connected to the interior of the cooling tank, and the medium outflow end of the delivery pump is fixedly installed and connected to the inflow pipe; the medium outflow end of the cyclone cooler is fixedly installed and connected to the cooling tank, and the medium inflow end of the cyclone cooler is fixedly installed and connected to the outflow pipe.

[0011] Optionally, the delivery pump is one of a water pump, a centrifugal pump, or a submersible pump.

[0012] This invention provides an amorphous magnetic core curing oven, which has the following beneficial effects:

[0013] This amorphous magnetic core curing oven, through the coordinated arrangement of the oven body, cooling components, and fixture plates, achieves convenient placement and removal of magnetic cores. Magnetic cores are placed in slots on the fixture plate, which is then placed on the cooling components. The oven body dries and cures the magnetic cores inside the fixture plate. Subsequently, during cooling, a conveying assembly flows coolant into the square tubes within the cooling components. The coolant absorbs heat from the square tubes, and heat from the fixture plate and magnetic cores is conducted to the coolant through the square tubes. The coolant carries the heat away, thus cooling the fixture plate and magnetic cores. Compared to existing technologies, this solution, by placing the fixture plate on the square tubes, achieves both cooling of the magnetic cores and facilitates the placement and removal of the fixture plate, thereby simplifying the removal of the magnetic cores. This allows for easy removal of individual magnetic cores from the oven without disassembling the water pipes or fixture plate, significantly improving work efficiency. Attached Figure Description

[0026] Please see Figures 1 to 8 The present invention provides a technical solution: an amorphous magnetic core curing oven, comprising an oven body 1, on which a door 101 is rotatably mounted.

[0027] The oven body 1 is used to dry and cure the magnetic core. The oven body 1 includes, but is not limited to, E-series magnetic core ovens, specifically BINDER E-series drying ovens and drying ovens from Germany.

[0028] An amorphous magnetic core curing oven also includes a cooling component and multiple fixture plates 10. The cooling component includes a conveying assembly and a support assembly.

[0029] The fixture plate 10 is used to support and hold the various amorphous magnetic cores. The cooling components are used to cool the fixture plate 10 and the various amorphous magnetic cores located within it.

[0030] The support assembly includes a first support box 5, a second support box 6, and multiple cooling components. The first support box 5 is fixedly installed on one inner side wall of the oven body 1, and the second support box 6 is fixedly installed on the other inner side wall of the oven body 1, with the first support box 5 and the second support box 6 being parallel.

[0031] The support assembly supports the fixture plate 10 and facilitates heat exchange within it. By installing the support assembly inside the oven body 1, the fixture plate 10 can be cooled within the oven body 1. The fixture plate 10 is placed on the cooling element, and during cooling, heat from the fixture plate 10 and each magnetic core is conducted to the cooling element.

[0032] The cooling components are arranged longitudinally in sequence, and each cooling component includes multiple square tubes 9, which are arranged transversely in sequence. The two ends of each square tube 9 are fixedly installed to the first support box 5 and the second support box 6, respectively, and are connected to both. Each fixture plate 10 is placed above its respective cooling component. Multiple fins 12 are fixedly connected to the inner top wall of each square tube 9, and the lower surface of the fixture plate 10 abuts against the upper surface of the square tube 9.

[0033] The first support box 5 and the second support box 6 are both connected to the interior of the square tube 9. When the cooling medium flows within the first support box 5, each square tube 9, and the second support box 6, it absorbs heat from the square tube 9, thereby cooling it. The heat from each magnetic core is conducted to the fixture plate 10, and the heat from the fixture plate 10 is conducted to the multiple square tubes 9. The cooling medium inside the multiple square tubes 9 absorbs heat, carries the heat, transforms into a heat medium, and is discharged, thus cooling the amorphous magnetic core. The fins 12 inside the square tube 9 are used to enhance heat conduction efficiency and accelerate the flow of heat from the magnetic core and fixture plate 10 into the cooling medium.

[0034] Specifically, the jig plate 10 has multiple placement slots 11 for placing magnetic cores.

[0035] The placement slots 11 on the jig plate 10 are used to hold the magnetic cores. At the same time, the placement slots 11 can limit the magnetic cores and prevent them from moving due to magnetic attraction.

[0036] Specifically, an inflow pipe 7 is fixedly installed on the top wall of the first support box 5 and the two are connected, and an outflow pipe 8 is fixedly installed on the top wall of the second support box 6 and the two are connected.

[0037] The inlet pipe 7 is used to inject cold medium into the first support box 5. The outlet pipe 8 is used to discharge the hot medium that has absorbed heat from the second support box 6. The cold medium flows sequentially through the inlet pipe 7, the first support box 5, and each square pipe 9. When the cold medium flows in the square pipe 9, it absorbs heat and is converted into hot medium. The hot medium flows sequentially through each square pipe 9, the second support box 6, and the outlet pipe 8.

[0038] More specifically, the conveying assembly includes a cooling tank 2, a conveying pump 3, and a cyclone cooler 4. The cooling tank 2 is fixedly installed on an outer side wall of the oven body 1, the conveying pump 3 is fixedly installed on the cooling tank 2, and the cyclone cooler 4 is fixedly installed on an outer side wall of the cooling tank 2. The cooling tank 2 contains coolant. The medium inflow end of the conveying pump 3 is connected to the interior of the cooling tank 2, and the medium outflow end of the conveying pump 3 is fixedly installed and connected to the inflow pipe 7. The medium outflow end of the cyclone cooler 4 is fixedly installed and connected to the cooling tank 2, and the medium inflow end of the cyclone cooler 4 is fixedly installed and connected to the outflow pipe 8. The conveying pump 3 is one of a water pump, a centrifugal pump, or a submersible pump.

[0039] The cooling tank 2 is used to hold coolant (a cold or hot medium), which may include, but is not limited to, water. The transfer pump 3 is used to draw and transport the coolant from the cooling tank 2. The cyclone cooler 4 is used to cool the coolant. One-way valves are installed on both the inlet pipe 7 and the outlet pipe 8 to prevent backflow of the coolant. The transfer pump 3 draws the coolant from the cooling tank 2 and transports it through the inlet pipe 7 to the first support box 5. The coolant in the first support box 5 flows into each square tube 9, where it absorbs heat. The heat from the fixture plate 10 and each magnetic core is conducted to the coolant in the square tubes 9, thereby cooling the magnetic cores. After absorbing heat, part of the coolant vaporizes, and the heat transfer medium (including high-temperature liquid coolant and high-temperature gaseous coolant) flows into the second support box 6. The heat transfer medium in the second support box 6 flows into the cyclone cooler 4 through the outflow pipe 8. The cyclone cooler 4 dissipates heat and cools the heat transfer medium, and the cooled coolant flows back into the cooling box 2. A pressure relief valve is installed on the top wall of the cooling box 2.

[0040] The oven body 1 is closed after the magnetic core is dried and cured. The amorphous magnetic core curing oven shown in this technical solution can cool the magnetic core without removing it from the oven body 1. Drain valves are installed on the bottom walls of the first support box 5 and the second support box 6 to drain the coolant inside the first support box 5 and the second support box 6 as needed.

[0041] In practical implementation, this technical solution also includes other components and electrical equipment to ensure that the amorphous magnetic core curing oven can be fully implemented and operated according to different working conditions.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
