Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] The following is combined Figures 1 to 7 The present invention describes an intelligent water-cooling device and control system for SVG power modules.

[0022] like Figures 1 to 2As shown, in one embodiment, an intelligent water-cooling device for an SVG power module includes a high-level water tank 100, a main circulation pump 210, a dual-stage filter 220, a deionizer 300, an external radiator 600, and an electric heater 700, which are arranged in sequence and connected by pipelines in sequence. An expansion tank 230 is arranged in parallel between the main circulation pump 210 and the dual-stage filter 220. A main pipeline 410, a branch pipeline 420, and a manifold 430 are connected in sequence between the deionizer 300 and the external radiator 600. A water-cooled plate 500 is attached to the SVG power module. The branch pipeline 420 passes through the water-cooled plate 500. The external radiator 600 and the electric heater 700 are connected by a return water pipeline 440.

[0023] The aforementioned intelligent water-cooling device for SVG power modules effectively removes impurities and ions from the cooling water through a multi-stage water treatment structure involving filtration and deionization, preventing pipe blockage and corrosion and ensuring long-term stable operation of the cooling system. The expansion tank 230, in conjunction with the high-level water tank 100, provides dual protection for stable pipe pressure, reducing leakage risks and improving system reliability. The external radiator 600 and electric heater 700 work together to efficiently dissipate heat and prevent icing in low-temperature environments, making the system adaptable to different ambient temperatures and applicable to a wide range of conditions. The overall piping and water-cooled plate assembly structure is simple, with a clear cooling water circulation path, high heat exchange efficiency, and precise matching of the SVG power module's heat dissipation requirements, while also facilitating installation and maintenance.

[0024] like Figure 2 As shown, in one embodiment, the water-cooled plate 500 includes a mounting base 510 and a cover plate 520; the bottom surface of the mounting base 510 is attached to the SVG power module, and a first cooling channel 516 is provided inside the mounting base 510. The two ends of the first cooling channel 516 respectively pass through the two ends of the mounting base 510. The other side of the mounting base 510 is set as an open structure. The cover plate 520 is installed at one end of the open structure of the mounting base 510 to close the first cooling channel 516. The branch pipe 420 is connected to the two ends of the first cooling channel 516.

[0025] Specifically, the bottom surface of the mounting base 510 is attached to the SVG power module to achieve heat conduction, the internal first cooling channel 516 provides a flow path for cooling water, the cover plate 520 closes the open structure of the mounting base 510, allowing the cooling water to flow in a directional manner within the channel, and the branch pipe 420 is connected to both ends of the channel to form a cooling water circulation loop.

[0026] The cooling channel is reliably sealed to prevent cooling water leakage; the mounting base 510 is directly attached to the SVG power module, shortening the heat conduction path and improving heat exchange efficiency; the detachable structure of the cover plate 520 and the mounting base 510 facilitates the cleaning and maintenance of the cooling channel in the future.

[0027] In one embodiment, the upper surface of the cover plate 520 is provided with a plurality of slots 5241, the slots 5241 being oriented in the same direction as the first cooling channel 516, and the slots 5241 being used to pass through other branch pipes 420.

[0028] Specifically, the slot 5241 on the cover plate 520 is aligned with the first cooling channel 516, providing dedicated space for additional branch pipes 420 to pass through, so that multiple branch pipes 420 can be neatly arranged in the same direction.

[0029] The layout of the multi-branch pipe 420 has been optimized to avoid pipe entanglement and crossing, saving installation space; it also serves to limit the branch pipe 420, improving the regularity and stability of the pipe layout and reducing the risk of pipe wear.

[0030] In one embodiment, the mounting base 510 includes a base plate 511, an end plate 512, a side plate 513, and a first bent plate 514. The two end plates 512 are located at both ends of the upper surface of the base plate 511, and the two side plates 513 are located on both sides of the upper surface of the base plate 511. The height of the end plate 512 is greater than the height of the side plate 513. One end of the end plate 512 and one end of the side plate 513 are connected by the first bent plate 514. The first bent plate 514 bends toward the center of the base plate 511, and the first bent plate 514 and the base plate 511 form a mounting opening 5141.

[0031] Specifically, the base plate 511, end plate 512, and side plate 513 constitute the main frame of the fixed seat 510. The end plate 512 and the side plate 513 are connected by the first bent plate 514 to form a closed profile. The mounting opening 5141 formed by the first bent plate 514 and the base plate 511 provides an assembly positioning reference for the cover plate 520.

[0032] The mounting bracket 510 has a stable overall structure and strong load-bearing capacity, and can fit tightly against the SVG power module while maintaining structural integrity; the design of the mounting port 5141 provides precise positioning for the assembly of the cover plate 520, improving assembly efficiency and connection reliability.

[0033] In one embodiment, the cover plate 520 includes a top plate 521, a second bent plate 522, and abutment plate 523; the bottom plate 511 is attached to the top surface of the side plate 513 and is located between the two end plates 512; the second bent plate 522 is disposed at the corner of the top plate 521; the outer surface of the second bent plate 522 is attached to the inner surface of the first bent plate 514; the abutment plate 523 is disposed on the inner surface of the second bent plate 522; the bottom surface of the abutment plate 523 abuts against the bottom surface of the mounting opening 5141; a cut 5232 is provided on one side of the connection between the abutment plate 523 and the second bent plate 522; a first mounting hole 5111 and a second mounting hole 5231 are respectively provided on the mounting opening 5141 and the abutment plate 523; the central axes of the first mounting hole 5111 and the second mounting hole 5231 coincide.

[0034] Specifically, the top plate 521 fits against the top surface of the side plate 513 to form a closed structure. The fit between the second bent plate 522 and the first bent plate 514 and the abutment plate 523 abuts against the mounting port 5141, so as to achieve precise alignment between the cover plate 520 and the fixing seat 510. The fixed connection is completed through the coaxial mounting hole, and the cutout 5232 is adapted to the assembly space.

[0035] The assembly precision and sealing performance of the cover plate 520 and the mounting base 510 are greatly improved, further preventing cooling water leakage; the connection structure is robust and can withstand the pressure impact during the cooling water circulation process, extending the service life of the water-cooled plate 500.

[0036] In one embodiment, the end plate 512 has a through opening 515 at its center. The first cooling channel 516 includes two semi-circular cavities 5161 and two spiral flow channels 5162. The flat ends of the two semi-circular cavities 5161 are respectively opposite to the two through openings 515 and are connected to the through openings 515. The two spiral flow channels 5162 are symmetrically arranged between the two semi-circular cavities 5161, and the ends of the spiral flow channels 5162 are connected to one side of the arc end of the semi-circular cavity 5161. A second cooling channel 517 is also provided on one side of the first cooling channel 516. The second cooling channel 517 is arranged close to the end plate 512, the first bent plate 514 and the side plate 513, and the two ends of the second cooling channel 517 are respectively connected to the two semi-circular cavities 5161.

[0037] Specifically, after the cooling water enters the semi-circular cavity 5161 through the through-hole 515, it flows into the symmetrically arranged spiral flow channel 5162 and the second cooling channel 517 that is close to the inner wall of the fixed base 510, forming a multi-path cooling circuit that fully covers the internal area of ​​the fixed base 510.

[0038] The cooling channels have a wide coverage area, which can evenly remove heat from different areas of the SVG power module and avoid local overheating; the multi-path design improves the efficiency of cooling water flow and further enhances the heat dissipation effect.

[0039] like Figures 3 to 5 As shown, in one embodiment, a first partition cavity is provided between the first cooling channel 516 and the second cooling channel 517, and a second partition cavity 519 is provided between the two spiral flow channels 5162. The second partition cavity 519 includes a cross-shaped portion 5191 and a guide portion 5192. The guide portion 5192 is located near one end of the semi-circular cavity 5161, and the arc-shaped protrusion of the guide portion 5192 can guide the cooling water entering the semi-circular cavity 5161 so that it enters the two spiral flow channels 5162 respectively. The cross-shaped portion 5191 is located between the two guide portions 5192.

[0040] Specifically, the first partition cavity 518 separates the first and second cooling channels 517 to avoid heat interference between the two channels; the guide section 5192 of the second partition cavity 519 guides the cooling water to be evenly distributed to the two swirling flow channels 5162, and the cross section 5191 optimizes the flow field distribution to make the water flow smoother.

[0041] Ensure the independent heat dissipation of each cooling channel and improve the uniformity of heat dissipation; the guide section 5192 realizes the rational distribution of cooling water, avoids local water flow blockage, improves circulation efficiency, and further optimizes the heat dissipation effect.

[0042] like Figure 6 and Figure 7 As shown, in one embodiment, a plurality of positioning blocks 524 are spaced apart on the upper surface of the top plate 521. The lower half of the positioning block 524 is a rectangular structure and the upper half of the positioning block 524 is a semi-circular structure. The slot 5241 is arranged along the length direction of the positioning block 524 and passes through both ends of the positioning block 524. The slot 5241 is arranged in a circular columnar structure, and the central axis of the slot 5241 coincides with the central axis of one end of the semi-circular structure of the positioning block 524.

[0043] Specifically, positioning blocks 524 are spaced apart on the top plate 521, and their slots 5241 are circular columnar structures that fit the shape of the branch pipes 420. The corresponding design of the central axis ensures that the pipe running direction is consistent with the cooling channel.

[0044] The positioning block 524 provides precise positioning and stable support for the branch pipe 420, preventing the pipe from shifting or shaking during operation; the structural design of the positioning block 524 is adapted to the pipe installation requirements, improving the regularity of the pipe layout.

[0045] In one embodiment, a through groove 5242 is provided on the inner surface of the slot 5241 away from the top plate 521. The through groove 5242 is used for the branch pipe 420 to be inserted. Multiple interval grooves 5243 are provided on both sides of the end of the positioning block 524 connected to the top plate 521. The multiple interval grooves 5243 are spaced apart along the length direction of the positioning block 524.

[0046] Specifically, the through groove 5242 provides a convenient insertion path for the branch pipe 420 without complicated assembly operations; the spacer groove 5243 optimizes the connection compatibility between the positioning block 524 and the top plate 521, while reserving a certain adjustment space for pipe installation.

[0047] The installation and disassembly process of the branch pipe 420 is simplified, improving the convenience of maintenance; the spacer groove 5243 enhances the structural flexibility of the positioning block 524, enabling it to better adapt to different installation scenarios and improve the overall adaptability of the device.

[0048] In one embodiment, an intelligent water-cooling control system for an SVG power module, applied to the intelligent water-cooling device for an SVG power module according to any of the above embodiments, includes the following steps: The elevated water tank 100 stores cooling water and provides a stable initial water pressure, while the expansion tank 230 simultaneously maintains stable pressure inside the pipeline. The main circulation pump 210 draws and pressurizes the cooling water. After impurities are removed by the dual-stage filter 220 and the water quality is purified by the deionizer 300, the clean cooling water flows through the main pipeline 410 and the branch pipeline 420 through the water-cooled plate 500 that has absorbed the heat of the SVG power module. After absorbing heat, the hot water is collected through the manifold 430 and flows into the external radiator 600 for heat dissipation. The cooled water flows through the electric heater 700, which starts heating as needed to prevent the pipes from freezing. The treated cooling water flows back to the high-level water tank 100 to complete the circulation.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
