Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically to a high-power multi-winding air-cooled reactor. Background Technology

[0002] Existing reactors mainly use air-cooled reactors and water-cooled reactors. Based on the reactor structure, they are divided into wire-wound and foil-wound types. Currently, the most commonly used high-power inductors above 300A are mainly air-cooled foil-wound reactors. Water-cooled reactors are gradually being phased out of the market due to the high cost of water-cooling tubes and high failure rate at low temperatures. Wire-wound reactors are also not accepted by the market because their winding process is more complex and the cost is higher under high power conditions.

[0003] In the production of 300A high-power reactors, additional air ducts are required to address the temperature rise of the reactor coils, which increases the reactor's size, weight, and manufacturing cost. At the same time, the coils of this type of reactor are basically wound by hand, making it difficult to automate production and thus limiting its production capabilities. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a high-power multi-winding air-cooled reactor with advantages such as low production cost and strong heat dissipation, which can be processed by automated winding equipment and effectively improve manufacturing efficiency.

[0005] The technical solution adopted by this utility model is as follows: a high-power multi-winding air-cooled reactor, including a reactor body, the reactor body including a coil assembly and a fixing component; the coil assembly includes an iron core, on which multiple layers of vertically wound coils are sleeved, and multiple sets of connecting copper busbars electrically connected to the vertically wound coils are fixed at both ends of the iron core; multiple sets of cooling fans are provided above the coil assembly; the fixing component includes a fixing component located below each connecting copper busbar corresponding to the iron core, and the connecting copper busbar is fixed on the copper busbar fixing component.

[0006] In this technical solution, the reactor body adopts a vertically wound coil structure. Vertical winding of the coil can realize automated production of products in batches, reducing product costs. Vertically wound coils can effectively increase the heat dissipation area of ​​the product. At the same time, the cooling fan located on the coil assembly can efficiently dissipate heat inside the coil assembly, reduce the heat generated during equipment operation, and improve the stability of equipment operation.

[0007] Preferably, a fan mounting bracket for installing a cooling fan is fixed above the coil assembly.

[0008] Preferably, the coil assembly has symmetrically arranged base mounting brackets on both sides below it.

[0009] Preferably, the copper busbar fixing component is provided with fixing screws for fixing and connecting the copper busbar.

[0010] Preferably, the multi-layer vertical winding coil includes several coil units connected in parallel, and heat dissipation channels are provided between adjacent coil units.

[0011] The beneficial effects of this utility model are as follows: The reactor body provided by this utility model adopts a vertically wound coil structure, which enables automated mass production and reduces product costs; a heat dissipation channel is provided between adjacent coil units, resulting in a larger heat dissipation area, and the heat dissipation airflow generated by the cooling fan achieves uniform heat dissipation, which has a better heat dissipation effect compared with the conventional foil winding process; since the coils do not need to be coiled together, manufacturing processes can be reduced and costs can be lowered, and the use of vertically wound coils can also reduce the proximity effect; the overall performance of the product is significantly improved, and it has high practical value.

[0016] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0018] like Figure 1 and Figure 2As shown, a specific embodiment of this utility model provides a high-power multi-winding air-cooled reactor. This type of reactor has superior heat dissipation capabilities and can improve manufacturing efficiency. Specifically, it includes a reactor body, which includes a coil assembly and a fixing member 400. The coil assembly includes an iron core 100, on which multiple layers of vertically wound coils 200 are sleeved. Multiple sets of connecting copper busbars 300 electrically connected to the vertically wound coils 200 are fixed at both ends of the iron core 100. Multiple sets of cooling fans 500 are provided above the coil assembly. The fixing member 400 includes a fixing member 400 located below each connecting copper busbar 300 of the iron core 100, and the connecting copper busbars 300 are fixed on the copper busbar fixing member 400.

[0019] like Figure 1 and Figure 2 As shown, with the above configuration, the reactor body provided in this embodiment consists of a coil assembly and a fixing component 400. The coil assembly adopts a vertically wound coil 200 structure. Vertical winding of the coil can realize automated production of products in batches, reducing product costs. At the same time, the vertically wound coil 200 can also effectively increase the heat dissipation area of ​​the product. The cooling fan 500 located on the coil assembly can efficiently dissipate heat inside the coil assembly, reduce the heat generated during equipment operation, and improve the stability of equipment operation. The fixing component 400 can stably install the connecting copper busbar 300 on the iron core 100, making the overall structure more stable. The copper busbar fixing component 400 is provided with fixing screws for fixing the connecting copper busbar 300, which facilitates fixing the copper busbar structure or connecting wire harness.

[0020] like Figure 1 and Figure 2 As shown, since a cooling fan 500 needs to be installed above the coil assembly, this embodiment has a fan mounting bracket 600 fixed above the coil assembly to mount the cooling fan 500. In this embodiment, two sets of cooling fans 500 are arranged, and two mounting positions are correspondingly provided on the fan mounting bracket 600. When this product is used, the entire reactor structure needs to be installed on the corresponding equipment. In this embodiment, symmetrically arranged base mounting brackets 700 are provided on both sides below the coil assembly. In practical applications, the fixing component 400, the fan mounting bracket 600, and the base mounting bracket 700 all adopt sheet metal structure and are fixed by screws, which has higher structural stability.

[0021] like Figure 1 and Figure 2As shown, the multi-layer vertically wound coil 200 provided in this embodiment includes several coil units connected in parallel, with heat dissipation channels between adjacent coil units. The coil units, arranged in parallel, can be fixed with tape. Due to the heat dissipation channels between adjacent coil units, the heat dissipation area is larger, and combined with the heat dissipation airflow generated by the cooling fan 500, uniform heat dissipation is achieved. Compared to conventional foil winding processes, this method offers superior heat dissipation. Since the coils do not need to be coiled together, manufacturing processes are reduced, costs are lowered, and the use of vertically wound coils can also reduce the proximity effect, thereby improving the overall performance of the product.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
