Abstract
Description
Technical Field
[0001] This application relates to the field of reactors, and more particularly to a heat-dissipating reactor frame. Background Technology
[0002] As a key component in power systems, the performance stability and heat dissipation efficiency of reactors are closely related. Traditional reactor frames mostly adopt an integrated or simple split design. Although the integrated frame structure is stable, it lacks flexibility when facing different coil length requirements, requiring separate mold manufacturing for each specification, resulting in high production costs, long production cycles, and low material utilization.
[0003] While existing modular frame designs (such as two-part structures) improve assembly efficiency to some extent, achieving insulation and fastening through the insertion of two cylindrical sections and simplifying the wrapping process after enameled wire winding, their fixed number of components makes them inflexible in adapting to variations in coil axial length. In production, to meet the coil length requirements of different power levels, a large number of complete frame components of varying specifications still need to be prepared, especially the end structures, which are repeatedly manufactured, making it difficult to achieve mass production of standard end components to reduce costs.
[0004] Furthermore, the coils of reactors generate significant heat during operation, and traditional frame structures often have limitations in heat dissipation design, such as relying solely on end plate slots or surface air ducts, resulting in insufficient heat dissipation efficiency. How to improve the manufacturing flexibility to adapt to different coil length requirements while ensuring the frame's insulation reliability and mechanical strength, and how to effectively optimize the heat dissipation path to reduce temperature rise, have become urgent problems to be solved in reactor frame design. Utility Model Content
[0005] In order to improve the problems of poor coil length adaptability and inability to standardize and mass-produce end components due to the fixed specifications of traditional reactor frames, and to improve the efficiency of large-scale manufacturing, this application provides a heat-dissipating reactor frame.
[0006] This application provides a heat-dissipating reactor frame, which adopts the following technical solution:
[0007] A heat-dissipating reactor frame, comprising:
[0008] The first end skeleton member includes a first winding portion and a first end plate disposed at one end of the first winding portion;
[0009] The second end skeleton member includes a second winding portion and a second end plate disposed at one end of the second winding portion;
[0010] The intermediate connecting skeleton component is prefabricated according to the winding requirements;
[0011] Wherein, the end of the first winding portion away from the first end plate is detachably connected to one end of the intermediate connecting skeleton member, and the end of the second winding portion away from the second end plate is detachably connected to the other end of the intermediate connecting skeleton member. The outer peripheral surfaces of the first winding portion, the second winding portion, and the intermediate connecting skeleton member together define the winding space.
[0012] By adopting the above technical solution, a three-part modular skeleton structure is achieved. The prefabricated length of the intermediate connecting skeleton components adapts to the needs of coils of different lengths. The first and second end skeleton components can be standardized for mass production, thereby reducing manufacturing costs and improving the efficiency of large-scale manufacturing. The integrated design of the winding space ensures structural stability and solves the resource waste problem caused by the rigid specifications of traditional skeletons.
[0013] Optionally, the intermediate connecting skeleton is an integrally formed cylindrical structure.
[0014] By adopting the above technical solutions, the integrated cylindrical structure enhances the mechanical strength of the intermediate connecting skeleton and avoids the deformation risk caused by segmented connections; at the same time, the integral molding simplifies the production process and ensures the accuracy of length prefabrication.
[0015] Optionally, the first winding portion and the intermediate connecting skeleton member, as well as the second winding portion and the intermediate connecting skeleton member, are detachably connected through a plug-in structure.
[0016] By adopting the above technical solutions, the plug-in structure enables rapid and precise assembly, thereby improving production efficiency.
[0017] Optionally, the plug-in structure includes a plug-in protrusion located at the end of the intermediate connecting skeleton member, and a plug-in recess correspondingly located on the first winding portion and / or the second winding portion.
[0018] By adopting the above technical solution, precise positioning and secure connection are achieved, eliminating misalignment issues during assembly. The convex-concave design enhances mechanical interlocking force and improves impact resistance. This plug-in structure is easy to injection mold, which helps reduce manufacturing costs and supports high-precision production.
[0019] Optionally, heat dissipation grooves are formed on the outer peripheral surfaces of the first winding portion, the intermediate connecting skeleton member, and the second winding portion along their respective length directions, and the positions of the heat dissipation grooves on the first winding portion, the intermediate connecting skeleton member, and the second winding portion correspond to each other, so that the heat dissipation grooves on the three components can be completely assembled into a continuous longitudinal heat conduction groove.
[0020] By adopting the above technical solution, an efficient vertical heat dissipation path can be easily established, which helps to reduce thermal resistance, avoid the formation of local hot spots, and improve overall heat dissipation efficiency. The heat dissipation slots on the three separate components correspond to form a continuous channel, which facilitates airflow, enhances the cooling effect, and reduces the impact of temperature rise on performance.
[0021] Optionally, the longitudinal heat-conducting groove is disposed through the first end plate and the second end plate.
[0022] By adopting the above technical solution, the end barrier of the heat dissipation path is broken, preventing heat from accumulating at the first and second end plates. The heat dissipation range is extended to the edge of the frame, enhancing the airflow exchange efficiency and helping to reduce temperature rise.
[0023] Optionally, a transverse heat-conducting groove is provided on one side of the first end plate and the second end plate opposite to each other. One end of the transverse heat-conducting groove is connected to the longitudinal heat-conducting groove, and the other end extends to the outermost end of the first end plate or the second end plate.
[0024] By adopting the above technical solution, a radial heat dissipation network is constructed through horizontal heat conduction grooves, further expanding the heat dissipation surface area. The heat dissipation design at the edges of the first and second end plates directly connects to the external cooling environment, enhancing heat exchange efficiency.
[0025] Optionally, the surfaces of the first end skeleton, the second end skeleton, and the intermediate connecting skeleton are coated with a high thermal conductivity insulating coating.
[0026] By adopting the above technical solutions, heat conduction efficiency is improved while ensuring electrical insulation safety, system reliability is enhanced, and the overall heat dissipation performance of the frame is strengthened.
[0027] Optionally, the first end skeleton member and the second end skeleton member have the same structure and dimensions.
[0028] By adopting the above technical solutions, the production of the end components of the skeleton is fully standardized. This significantly reduces mold costs and inventory management burden, and improves manufacturing efficiency; the identical design ensures interchangeability, accelerates the skeleton assembly process, and reduces production downtime.
[0029] In summary, this application includes at least one of the following beneficial technical effects:
[0030] 1. This application utilizes a three-part structural design, which can be fully assembled from a first end frame component, a second end frame component, and an intermediate connecting frame component. Furthermore, the intermediate connecting frame component can be prefabricated to different lengths according to winding requirements, thus flexibly adapting to customized needs for different coil lengths. This significantly improves production flexibility. The first and second end frame components can be mass-produced as standard parts, reducing the cost of repeated mold development and optimizing resource utilization efficiency. Simultaneously, the three-part design simplifies the assembly process, facilitates maintenance and replacement, and avoids the waste of a single frame component. The winding space is jointly defined by the outer circumferences of the three components, ensuring stable coil installation, reducing the risk of misalignment during winding, and improving the overall reliability and consistency of the reactor.

By creating corresponding heat dissipation slots on the outer circumference of the first winding section, the intermediate connecting frame, and the second winding section, the heat dissipation slots of the three components are completely assembled into a continuous longitudinal heat conduction channel, creating an efficient axial heat dissipation path. This significantly reduces thermal resistance, avoids the formation of local hot spots, and improves overall heat dissipation efficiency. The corresponding slot design ensures uniform heat conduction, extends coil life, and increases reactor power density. The continuous slot body also facilitates airflow, enhances cooling effect, and reduces the impact of temperature rise on performance.

[0038] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail below.
[0039] Example 1:
[0040] Embodiment 1 of this application discloses a heat-dissipating reactor frame. (Refer to...) Figure 1 A heat-dissipating reactor frame includes a first end frame 1, an intermediate connecting frame 2, and a second end frame 3 connected in sequence; the first end frame 1 includes a first winding portion 11 and a first end plate 12 integrally formed at one end of the first winding portion 11; the length of the intermediate connecting frame 2 is pre-fabricated according to the winding requirements; the second end frame 3 includes a second winding portion 31 and a second end plate 32 disposed at one end of the second winding portion 31.
[0041] Reference Figure 1 The inner and outer surfaces of the first end skeleton 1, the second end skeleton 3, and the intermediate connecting skeleton 2 are coated with a high thermal conductivity insulating coating, which can improve heat conduction efficiency while ensuring electrical insulation safety. The high thermal conductivity insulating coating reduces interface thermal resistance and, in conjunction with the heat dissipation groove 51 design, enhances overall heat dissipation performance, reduces temperature rise, and extends reactor life. In addition, the insulating properties prevent short circuit risks and improve system reliability; the coating process is simple to apply, compatible with various skeleton materials, and enhances product durability and environmental adaptability. In this embodiment, the high thermal conductivity insulating coating is a graphene heat dissipation coating.
[0042] Reference Figure 2 The end of the first winding portion 11 away from the first end plate 12 is detachably connected to one end of the intermediate connecting skeleton member 2, and the end of the second winding portion 31 away from the second end plate 32 is detachably connected to the other end of the intermediate connecting skeleton member 2. The outer peripheral surfaces of the first winding portion 11, the second winding portion 31 and the intermediate connecting skeleton member 2 together define the winding space.
[0043] This application utilizes a three-part structural design, which can be fully assembled from a first end frame 1, a second end frame 3, and an intermediate connecting frame 2. Furthermore, the intermediate connecting frame 2 can be prefabricated to different lengths according to winding requirements, thus flexibly adapting to customized needs for different coil lengths. This significantly improves production flexibility. The first end frame 1 and the second end frame 3 can be mass-produced as standard parts, reducing the cost of repeated mold development and optimizing resource utilization efficiency. Simultaneously, the three-part design simplifies the assembly process, facilitates maintenance and replacement, and avoids the waste of a single frame. The winding space is jointly defined by the outer circumferences of the three components, ensuring stable coil installation, reducing the risk of misalignment during winding, and improving the overall reliability and consistency of the reactor.
[0044] Reference Figure 2 To facilitate fully standardized production of the skeleton end components, the first end skeleton component 1 and the second end skeleton component 3 have the same structure and dimensions. This significantly reduces mold costs and inventory management burden, further improving the efficiency of large-scale manufacturing; the identical design ensures interchangeability, accelerates the assembly process, and reduces production downtime. Furthermore, standardization improves product quality consistency and supports large-scale customized applications.
[0045] Reference Figure 2 The intermediate connecting skeleton component 2 is an integrally formed cylindrical structure, which can enhance the mechanical strength and stability of the skeleton, prevent deformation or breakage caused by separate connection, and the integral forming simplifies the manufacturing process, effectively ensures the length prefabrication accuracy, thereby reducing production defects and further optimizing the performance consistency of the reactor.
[0046] Reference Figure 2 The first winding portion 11 and the intermediate connecting skeleton 2, as well as the second winding portion 31 and the intermediate connecting skeleton 2, are detachably connected via a plug-in structure 4. The plug-in structure 4 includes a plug-in protrusion 41 integrally formed on the end of the intermediate connecting skeleton 2, and plug-in recesses 42 correspondingly formed on the first winding portion 11 and / or the second winding portion 31. This significantly simplifies the assembly process and improves production efficiency; furthermore, the plug-in structure 4 is easy to injection mold, reducing manufacturing costs and supporting high-precision production.
[0047] Reference Figure 2 and Figure 3Heat dissipation grooves 51 are formed along their respective length directions on the outer peripheral surfaces of the first winding portion 11, the intermediate connecting skeleton member 2, and the second winding portion 31. The heat dissipation grooves 51 on these three components are positioned correspondingly, allowing them to be completely assembled into a continuous longitudinal heat-conducting groove 5, creating an efficient longitudinal heat dissipation path. In this embodiment, multiple longitudinal heat-conducting grooves 5 are provided and evenly distributed along the circumference of the winding space. This helps reduce thermal resistance, avoids the formation of local hot spots, and improves overall heat dissipation efficiency. The corresponding groove design of the heat dissipation grooves 51 ensures uniform heat conduction, which helps extend coil life and increase reactor power density. Furthermore, the corresponding groove positions of the heat dissipation grooves 51 on the three separate components form a continuous groove, facilitating airflow, enhancing cooling effect, and reducing the impact of temperature rise on performance.
[0048] Reference Figure 1 and Figure 3 The longitudinal heat-conducting groove 5 is designed to penetrate the first end plate 12 and the second end plate 32, breaking through the end barrier of the longitudinal heat dissipation path and preventing heat accumulation at the first end plate 12 and the second end plate 32. This extends the heat dissipation range to the edge of the frame, enhances airflow exchange efficiency, and reduces temperature rise. The longitudinal heat-conducting groove 5's design, penetrating the frame, ensures the continuity of heat conduction and improves the reliability of the reactor in high-temperature environments.
[0049] Example 2:
[0050] Embodiment 2 of this application discloses a heat-dissipating reactor frame. (Refer to...) Figure 4 The difference between this second embodiment and the first embodiment is that a transverse heat conduction groove 6 is provided on the opposite side of the first end plate 12 and the second end plate 32, and one end of the transverse heat conduction groove 6 is connected to the longitudinal heat conduction groove 5, and the other end extends to the outermost end of the first end plate 12 or the second end plate 32.
[0051] In this second embodiment, transverse heat-conducting grooves 6 are formed on opposite sides of the first end plate 12 and the second end plate 32, with one end precisely connected to the longitudinal heat-conducting groove 5 and the other end extending to the outer edge of their respective end plates, thereby constructing a three-dimensional heat dissipation network interwoven with longitudinal and transverse heat dissipation. When the coil end face is in close contact with the first end plate 12 and the second end plate 32 respectively, the longitudinal heat-conducting groove 5 longitudinally guides the heat accumulated in the middle section of the coil to the end plate areas at both ends. At this time, the transverse heat-conducting grooves 6 act as transverse heat dissipation branches, dynamically diverting the heat flow transferred by the longitudinal heat-conducting grooves 5 to the open space at the edges of the first end plate 12 and the second end plate 32, completely breaking through the physical bottleneck of heat accumulation at the ends of the traditional frame. This design significantly increases the actual effective heat dissipation area of the coil on the frame, while the airflow turbulence effect induced by the groove wall enhances the convective heat transfer efficiency; the groove structure extending to the outermost edge of the end plate establishes a direct connection channel with the external environment, realizing unobstructed heat transfer from the coil's internal generation area to the external environment, ensuring the heat dissipation performance of the frame.
[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
