Description

Technical Field

[0001] This utility model relates to the field of reactor technology, specifically to a corrosion-resistant water-cooled reactor. Background Technology

[0002] Currently, water cooling systems for reactors, conductors, and power devices in the power industry exchange heat generated by the devices with the outside environment through the circulation of coolant in water circuits, achieving a cooling effect. This cooling method has high heat dissipation efficiency and can meet the heat dissipation requirements of large-capacity power systems.

[0003] Existing stainless steel pipe water-cooled reactors use internal water channels in aluminum metal modules for cooling and heat dissipation. Although setting cooling channels on the cold plate has a certain heat dissipation effect, it is also easy for the cold plate to be corroded by the coolant after long-term use, and in severe cases, it will become "weathered", reducing cooling efficiency. At the same time, the aluminum profile is used to process the heat dissipation plate, which is complicated and costly. Because different metal materials are used at the water pipe interface, the coefficients of thermal expansion are inconsistent, which can easily lead to water leakage after a long time, and pose safety hazards such as leakage, short circuit and burnout. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of this utility model is to provide a corrosion-resistant water-cooled reactor to avoid corrosion of the cooling structure after long-term use, while improving the heat dissipation effect.

[0006] In this technical solution, each winding of the reactor assembly is provided with a cooling channel for installing a cooling structure. Each cold plate of the cooling assembly can be inserted into the cooling channel. The coolant is delivered to the cooling coil of each cold plate through a water distributor. As the cooling fluid circulates, it can carry away the heat generated by the operation of the reactor winding, thereby achieving efficient heat dissipation. The coolant is delivered through the cooling coil to avoid corrosion of the cold plate and ensure a stable heat dissipation effect.

[0007] Preferably, the surface of the cold plate is provided with a cooling groove for embedding the cooling coil, and the cooling coil is fixed by high-frequency induction brazing after being embedded in the cooling groove.

Detailed Implementation

[0018] 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.

[0019] 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.

[0020] like Figure 1 and Figure 2 As shown, a specific embodiment of this utility model provides a corrosion-resistant water-cooled reactor. This reactor adopts a pipe-type cooling structure to improve the cooling effect and avoid corrosion damage to the cold plate 400. Specifically, it includes a reactor assembly and a water-cooling assembly. The reactor assembly includes an iron yoke module 100, on which several iron cores 200 are arranged in parallel at intervals. Each group of iron cores 200 is provided with a winding 300, and each winding 300 is provided with a cooling channel 310 arranged along its length. The water-cooling assembly includes a water distributor 600 and cold plates 400 arranged in the cooling channels 310 of each winding 300. Cooling coils 500 are embedded on the surface of the cold plate 400. The output end and input end of the water distributor 600 are connected to each cooling coil 500 through a circulation pipe 700.

[0021] like Figure 1 and Figure 2 As shown, with the above configuration, in this embodiment, each winding 300 of the reactor assembly is mounted on the iron core 200 of the yoke module. At the same time, each winding 300 is provided with a cooling channel 310 for mounting the cooling structure. Each cold plate 400 of the cooling assembly can be inserted into the cooling channel 310. The coolant is delivered to the cooling coil 500 of each cold plate 400 through the water distributor 600. As the cooling coil 500 circulates, it can carry away the heat generated by the operation of the reactor winding 300, thereby achieving efficient heat dissipation. The coolant delivered through the cooling coil 500 can prevent the cold plate 400 from corroding and ensure a stable heat dissipation effect.

[0022] As mentioned earlier, in this embodiment, the cooling coil 500 circulates coolant to facilitate heat exchange between the cold plate 400 and the winding 300, achieving heat dissipation. To stably mount the cooling coil 500 on the cold plate 400, the surface of the cold plate 400 is provided with a cooling groove 410 for the cooling coil 500 to be embedded in. After the cooling coil 500 is embedded in the cooling groove 410, it is fixed by high-frequency induction brazing. This method of embedding the cooling coil 500 into the cooling groove 410 of the cold plate 400 and fixing it by welding not only facilitates pipe installation and connection but also reduces joint space. In practical applications, the cooling coil 500 is made of cupronickel, and the cold plate 400 is made of aluminum. Due to the high thermal conductivity of cupronickel, the combination of the aluminum cold plate 400 and the cupronickel embedded form not only provides high sealing reliability but also strong corrosion resistance, improving heat dissipation efficiency and simplifying and reliably processing during production.

[0023] like Figure 1As shown, this embodiment has mounting brackets 800 arranged in parallel at intervals at the lower end of the reactor assembly. The mounting brackets 800 can be used to fix the reactor structure. Since the reactor has a water distributor 600, this embodiment also has a fixing frame 900 connected to the yoke module 100 on one side of the lower end of the reactor assembly, and the water distributor 600 is mounted on the fixing frame 900. Thus, when the water distributor 600 is installed at the lower end of the reactor assembly, the interface of the cooling coil 500 can be arranged downwards. When the cooling coil 500 is connected to the water distributor pipe, condensation can be prevented from dripping into the winding 300, ensuring the safety of the reactor. In addition, the water distributor 600 is also connected to a water inlet pipe 610 for connecting the pipeline structure for transporting coolant.

[0024] 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.
