Description

Technical Field

[0001] The present invention relates to the technical field of reactors, and in particular to a corrosion-resistant water-cooled reactor. Background Art

[0002] At present, the water cooling system of reactors, conductors and power devices in the power industry exchanges the heat generated by the devices with the outside world through the circulation of coolant through water circuits to achieve the cooling effect. This cooling method has high heat dissipation efficiency and can meet the heat dissipation needs of large-capacity power systems.

[0003] The existing water-cooled reactor with stainless steel pipes adopts the internal water channel of aluminum metal module to implement cooling and heat dissipation. Although the cooling channel is set on the cold plate to have a certain heat dissipation effect, it is also easy to cause the cold plate to be corroded by the coolant after long-term use. In severe cases, it becomes "weathered" and reduces the cooling efficiency. At the same time, the heat dissipation plate is made of aluminum profiles, which has complicated processing technology and high cost. The water pipe interface position is easy to leak after a long time because of the inconsistent thermal expansion coefficients due to the use of different metal materials. There are safety hazards such as leakage, short circuit and burning. Summary of the invention

[0004] In view of the defects in the prior art, the object of the present invention is to provide a corrosion-resistant water-cooled reactor to avoid corrosion of the cooling structure after long-term use and to improve the heat dissipation effect.

Each cold plate of the cooling assembly can be inserted into the cooling channel. The coolant is transported to the cooling coil of each cold plate through a water distributor. As the coolant circulates, the heat generated by the operation of the reactor winding can be taken away, thereby implementing efficient heat dissipation. Transporting the coolant through the cooling coil can avoid corrosion of the cold plate and ensure a stable heat dissipation effect.

[0018] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0019] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the invention belongs.

[0020] like Figure 1 and Figure 2 As shown, a specific embodiment of the present invention provides a corrosion-resistant water-cooled reactor, which adopts a pipeline cooling structure to improve the cooling effect and avoid corrosion damage to the cold plate 400; specifically includes a reactor assembly and a water-cooling assembly; the reactor assembly includes an iron yoke module 100, on which are provided a plurality of iron cores 200 arranged in parallel and spaced relation, 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 a cold plate 400 arranged in the cooling channel 310 of each winding 300, and a cooling coil 500 is embedded in the surface of the cold plate 400, and the output end and the input end of the water distributor 600 are connected with each cooling coil 500 through a circulation pipeline 700.

[0021] like Figure 1 and Figure 2 As shown, through the above arrangement, each winding 300 of the reactor assembly in this embodiment is installed on the iron core 200 of the iron yoke module, and each winding 300 is provided with a cooling channel 310 for installing the cooling structure, and each cold plate 400 of the cooling assembly can be inserted into the cooling channel 310, and the coolant is transported to the cooling coil 500 of each cold plate 400 through the water distributor 600. As the coolant circulates, the heat generated by the operation of the reactor winding 300 can be taken away, thereby implementing efficient heat dissipation. The transportation of coolant through the cooling coil 500 can avoid corrosion of the cold plate 400, thereby ensuring a stable heat dissipation effect.

[0022] As mentioned above, in this embodiment, the cooling coil 500 circulates the cooling liquid so that the cold plate 400 and the winding 300 fully exchange heat to achieve heat dissipation. In order to stably install the cooling coil 500 on the cold plate 400, in this embodiment, the surface of the cold plate 400 is provided with a cooling groove 410 for the cooling coil 500 to be embedded. After the cooling coil 500 is embedded in the cooling groove 410, it is fixed by a high-frequency induction brazing process. In this way, the cooling coil 500 is embedded in the cooling groove 410 of the cold plate 400 and then fixed by a welding process, which not only facilitates the installation and connection of the pipeline, but also reduces the joint space; in actual application, the cooling coil 500 is made of a nickel silver tube and the cold plate 400 is made of an aluminum metal plate. Due to the high thermal conductivity of the nickel silver tube, the aluminum metal cold plate 400 combined with the nickel silver tube embedded tube form not only has high sealing reliability, but also has strong corrosion resistance, can improve the heat dissipation efficiency, and is simpler and more reliable to process during production.

[0023] like Figure 1As shown, in this embodiment, a mounting bracket 800 arranged in parallel and spaced relation is provided at the lower end of the reactor assembly. The mounting bracket 800 can be used to fix the reactor structure; since a water divider 600 is provided on the reactor, in this embodiment, a fixing bracket 900 connected to the iron yoke module 100 is also provided on one side of the lower end of the reactor assembly, and the water divider 600 is installed on the fixing bracket 900. In this way, when the water divider 600 is installed at the lower end of the reactor assembly, the interface of the cooling coil 500 can be arranged downward, and when the cooling coil 500 is connected to the water divider pipe, condensation in the pipeline can be prevented from dripping into the winding 300, thereby ensuring the safety of the reactor. In addition, the water divider 600 is also connected to a water inlet pipe 610 for connecting a pipeline structure for conveying coolant.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and specification of the present invention.
