Description

Technical Field

[0001] The utility model relates to the technical field of power supply equipment, in particular to a mounting structure of a synchronization module of a rectifier. Background Art

[0002] A rectifier, also widely known as an electroplating power supply, an electrolysis power supply or an electrophoresis power supply, is a kind of power supply equipment. The rectifier can be used to adjust current and voltage, that is, it can adjust the current and voltage of the input AC power supply to meet the requirements of different processes; the rectifier can also be used for AC-DC conversion, that is, through a rectification circuit, AC electrical energy is converted into DC electrical energy, and this process is very important in many fields. For example, the speed regulation of DC motors and the excitation regulation of generators all require the use of rectification technology. The rectifier plays a key role in industrial processes such as electroplating, aluminum anodizing, and electrolysis, providing the necessary power supply for these processes. The rectifier usually includes main circuits, filters, synchronization modules, transformers and other components, ensuring that alternating current is effectively converted into direct current, and the output direct current is stable and suitable for subsequent use requirements. Generally speaking, the rectifier is an important power supply equipment, which provides the necessary power support for various industrial applications that require direct current by adjusting and converting current.

[0003] There is a synchronization module in the rectifier. By means of the synchronization module, the energy conversion efficiency is improved and the energy loss is reduced, so that the rectifier can operate with higher efficiency and lower energy consumption while providing a stable DC output. At present, in the rectifier, the synchronization module is directly connected to the heat dissipation component through a conductive bottom plate, which results in the heat dissipation component being charged. When the heat dissipation component is water-cooled, minerals in the water are easily adsorbed on the pipe wall or the pipe orifice. As more and more adsorbed minerals accumulate, they will occupy the internal space of the pipeline, resulting in poor water flow and affecting the heat dissipation effect. Summary of the Utility Model

[0004] The utility model aims to solve the technical problems existing in the above-mentioned prior art, and provides a mounting structure of a synchronization module that is beneficial to the effective heat dissipation of the rectifier.

[0005] To solve the above technical problems, the utility model provides the following technical solutions:

[0006] A mounting structure of a synchronization module of a rectifier according to the utility model includes a rectifier mounting housing. A heat dissipation component is arranged in the rectifier mounting housing. A synchronization module is connected to the heat dissipation component. The synchronization module includes a PCB board; the synchronization module further includes a conductive bottom plate and a conductive strip. The PCB board connects the conductive bottom plate and the conductive strip. The synchronization module is connected to the heat dissipation component through the conductive bottom plate and the conductive strip. An insulating layer for isolating conduction is arranged between the conductive bottom plate and the heat dissipation component and between the conductive strip and the heat dissipation component.

[0007] For the installation structure of the synchronization module of a rectifier machine described in the present utility model, through the action of a conductive base plate and conductive bars, the synchronization module forms an integral whole, facilitating the installation of the synchronization module within the rectifier machine. Additionally, by providing an insulating layer that isolates conduction between the conductive bars of the synchronization module, the conductive base plate, and the heat dissipation component, it is possible to prevent the current on the synchronization module from being conducted to the heat dissipation component. When the heat dissipation component uses water cooling for heat dissipation, it effectively avoids minerals in the water from adsorbing on the pipe wall or pipe orifice, preventing the minerals from occupying the internal space of the pipe and ensuring smooth water flow, thereby ensuring effective heat dissipation of the heat dissipation component.

[0008] Furthermore, there are two conductive bars, which are respectively arranged on both sides of the conductive base plate; the insulating layer simultaneously covers the surfaces of the two conductive bars and the conductive base plate, or the number of insulating layers is the same as the number of conductive bars and the conductive base plate, and a layer of insulating layer is respectively provided on the surface of each conductive bar and the conductive base plate.

[0009] Furthermore, the material of the insulating layer is ceramic, the material of the conductive bar is copper, and the material of the conductive base plate is aluminum.

[0011] Furthermore, a part of the upper surface of the conductive bar is provided with a second protrusion, and the second protrusion is indirectly connected to the second output copper busbar.

[0012] Furthermore, the second protrusion on the conductive bar is conductively connected to the transformer assembly, and the transformer assembly is conductively connected to the second output copper busbar.

[0013] Furthermore, the parts of the upper surfaces of the two conductive bars without the second protrusion and the part of the surface of the conductive base plate without the first protrusion form an installation groove, and the PCB board is installed in the installation groove.

[0014] Furthermore, the heat dissipation component includes a heat dissipation partition board, and the synchronization module is connected to the heat dissipation partition board through the insulating layer; a U-shaped water channel is provided inside the heat dissipation partition board, and both ends of the U-shaped water channel penetrate through the wall surface of the heat dissipation partition board. One port of the U-shaped water channel is the water inlet, and the other port is the water outlet. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0022] For the convenience of understanding the present invention, the following will describe the present invention more comprehensively with reference to the relevant drawings.

[0023] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to another element and integrated with it, or there may be an intermediate element at the same time. The terms "installation", "one end", "the other end" and similar expressions used in this article are only for the purpose of illustration.

[0024] Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by those skilled in the technical field to which this technology belongs. The terms used in the description of this specification in this article are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. The term "and / or" used in this article includes any and all combinations of one or more of the related listed items.

[0025] In this embodiment, a specific implementation mode of the synchronous module installation structure of a rectifier is specifically provided. Among them, the rectifier in this embodiment can be a rectifier with a single-output structure or a rectifier with a dual-output structure. The so-called rectifier with a single-output structure means that only one load can be connected, while the rectifier with a dual-output structure can connect two loads at the same time and work independently of each other. In this embodiment, the rectifier with a dual-output structure is used as an example to describe the synchronous module installation structure.

[0026] See Figures 1-4, the installation structure of the synchronization module of the rectifier includes a rectifier installation housing 1. A heat dissipation component 2 is arranged inside the rectifier installation housing 1. A synchronization module 3 is connected to the heat dissipation component 2. The synchronization module 3 includes a PCB board 4. This PCB board 4 is an intelligent drive and protection circuit board. The circuit structure on the PCB board 4 and its realized functions are all prior arts, and the functions and circuit structure of the PCB board 4 itself are not the invention points of the present utility model. The synchronization module 3 also includes a conductive base plate 5 and conductive bars 6. The PCB board 4 connects the conductive base plate 5 and the conductive bars 6. The connection method is mainly that the PCB board 4 is detachably connected to both the conductive base plate 5 and the conductive bars 6 through fasteners. The synchronization module 3 is connected to the heat dissipation component 2 through the conductive base plate 5 and the conductive bars 6. An insulating layer 7 that isolates electricity conduction is arranged between the conductive base plate 5 and the heat dissipation component 2 and between the conductive bars 6 and the heat dissipation component 2. Through the action of the conductive base plate 5 and the conductive bars 6, the synchronization module 3 forms a whole, so as to facilitate the installation of the synchronization module 3 in the rectifier. Then, by arranging the insulating layer 7 that isolates electricity conduction between the conductive bars 6 and the conductive base plate 5 of the synchronization module 3 and the heat dissipation component 2, it can prevent the current on the synchronization module 3 from being conducted to the heat dissipation component 2. When the heat dissipation component 2 uses water cooling for heat dissipation, it can effectively avoid the adsorption of minerals in water on the pipe wall or pipe orifice, avoid the occupation of the internal space of the pipe by minerals, ensure the smooth flow of water, and thus ensure the effective heat dissipation of the heat dissipation component 2. Specifically, there are two conductive bars 6, which are respectively arranged on both sides of the conductive base plate 5. Each conductive bar 6 corresponds to a PCB board 4. The insulating layer 7 can be a whole piece, and the whole piece of insulating layer 7 simultaneously covers the surfaces of the two conductive bars 6 and the conductive base plate 5, or the number of insulating layers 7 is the same as the number of conductive bars 6 and the conductive base plate 5. For example, when the total number of the conductive base plate 5 and the conductive bars 6 is three, the number of insulating layers 7 is also three, and an insulating layer 7 is respectively arranged on the surface of each conductive bar 6 and the surface of the conductive base plate 5.

[0027] In a preferred embodiment, the material of the insulating layer 7 is ceramic. When using ceramic as the insulating layer 7, it has high mechanical strength, and ceramic also has high thermal conductivity, which means it can effectively conduct heat, facilitating the heat dissipation of the synchronization module 3 and the transformer component 8. The material of the conductive bar 6 is copper. The material of the conductive base plate 5 is aluminum. As a conductive material, aluminum has high cost-effectiveness, light weight, good electrical conductivity and corrosion resistance.

[0028] In a preferred embodiment, a first protrusion 9 is provided on the surface of one end of the conductive base plate 5, and a first output copper row 10 is connected to the first protrusion 9; a second protrusion 11 is provided on a part of the upper surface of the conductive strip 6. It can be understood that the second protrusion 11 only covers a part of the upper surface of the conductive strip 6, so that the cross-section of the conductive strip 6 in its width direction forms an L shape, and the second protrusion 11 is indirectly connected to the second output copper row 12. The parts of the upper surfaces of the two conductive strips 6 where the second protrusion 11 is not provided and the part of the surface of the conductive base plate 5 where the first protrusion 9 is not provided form an installation groove, and the two PCB boards 4 are installed in the installation groove. Through the setting of the foregoing structure, it is possible to prevent the PCB boards 4 installed in the installation groove and the electronic components on the PCB boards 4 from being touched and damaged. In addition, the first output copper row 10 and the second output copper row 12 are directly electrically connected to the positive and negative terminals of the load, so that the load receives the required stable current or stable voltage.

[0029] In a preferred embodiment, the second protrusion 11 on the conductive strip 6 is electrically connected to the transformer assembly 8, and the transformer assembly 8 is electrically connected to the second output copper row 12. The transformer assembly 8 includes a skeleton 14 for installing a magnetic core 13. The skeleton 14 is directly connected to the conductive base plate 5 of the synchronization module 3 through a fastener. A transformer conductive plate 15 is also connected to the skeleton 14. The material of the transformer conductive plate 15 can be copper. One end of the second output copper row 12 located inside the rectifier installation housing 1 is connected to the transformer conductive plate 15, so as to realize the indirect electrical connection between the second protrusion 11 on the synchronization module 3 and the second output copper row 12; in addition, a current sensor 16 is also provided on the second output copper row 12 to monitor the current level in the circuit in real time to protect the rectifier; in addition, a conductive member 17 for realizing soft connection (also called flexible connection) is connected to the conductive strip 6. One end of the conductive member 17 is connected to the transformer conductive plate 15. The conductive strip 6 and the transformer conductive plate 15 are soft-connected through the conductive member 17, which can realize the flexibility of the connection, and the soft connection has good electrical conductivity. The use of soft connections simplifies the installation process because they can bypass obstacles or make connections in narrow spaces. At the same time, if the device needs to be replaced or moved, the soft connections are also easier to handle.

[0030] In a preferred embodiment, refer to Figures 1-5, the heat dissipation component 2 includes a heat dissipation partition 18. The synchronization module 3 is connected to the heat dissipation partition 18 through an insulating layer 7. Since a rectifier with a dual-output structure is adopted in this embodiment, there are two sets of synchronization modules 3, and the two sets of synchronization modules 3 are respectively arranged on the two side walls of the heat dissipation partition 18. A U-shaped water channel is arranged inside the heat dissipation partition 18. Both ends of the U-shaped water channel penetrate through the wall surface of the heat dissipation partition 18. One port of the U-shaped water channel is the water inlet, and the other port is the water outlet. Water pipe connectors 19 are respectively arranged on the water inlet and the water outlet, and a water pipe sleeve 20 is sleeved on the water pipe connector 19. The water circulation flow is realized through the U-shaped water channel, which is convenient for dissipating heat inside the rectifier and taking away the heat in time.
