[0056] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element at the same time. The terms "installed", "one end", "the other end" and similar expressions used in the present invention are for illustrative purposes only.

[0057] This embodiment provides a rectifying device, such as Figures 1 to 2 As shown, it includes a control console 600, a main body 700, a first output member 800 and a second output member 900. The main body 700 is provided with a processing system, a power system and a rectifier unit. The rectifier unit includes at least two rectifier units 500 detachably connected to the main body 700. The rectifier units 500 are respectively connected to the processing system for communication and are respectively connected to the power system for electrical communication.

[0058] The control console 600 is in communication connection with the processing system;

[0059] The first output end of the rectifier unit 500 is electrically connected to the first output component 800, and the second output end of the rectifier unit 500 is electrically connected to the second output component 900. The first output component 800 and the second output component 900 are positive and negative to each other, and serve as the output pole of the rectifier device for external output.

[0060] The rectifier device of this embodiment is provided with a rectifier unit on the main body 700, and the rectifier unit includes at least two rectifier units 500 detachably connected to the main body 700, and the first output ends of the rectifier units 500 are electrically connected to the first output component 800, and the second output ends of the rectifier units 500 are electrically connected to the second output component 900. On the one hand, when facing a large rectifier power demand, a plurality of rectifier units 500 with smaller rectifier powers can be correspondingly provided to meet the demand, which can not only reduce the size of parts and the external dimensions of the equipment, but also reduce the performance requirements for electronic components. On the other hand, when the rectifier device of the present invention is applied below the maximum rectifier power that the equipment can provide, the surplus rectifier units 500 can also be easily disassembled or turned off, which is not only conducive to the stable output of the rectifier power supply, but also improves the overall utilization rate of the equipment, so that the configuration matches the actual demand without causing unnecessary waste of resources, and can solve the problem that the existing high-power rectifiers mostly adopt an integrated design, resulting in a relatively low utilization rate.

[0061] In addition, the rectifier units 500 are respectively connected to the processing system for communication, and the processing system can simultaneously control each rectifier unit 500, thereby ensuring the current sharing effect and avoiding the tediousness of separate control.

[0062] In this embodiment, as an example, the rectifier unit is provided with eight rectifier units 500, which are stacked in two columns. The first output component 800 includes an A output component 801 and an a output component 802, and the second output component 900 includes a B output component 901 and a b output component 902. The first output ends of one column of rectifier units 500 are electrically connected to the A output component 801, and the second output ends are electrically connected to the B output component 901. The first output ends of another column of rectifier units 500 are electrically connected to the a output component 802, and the second output ends are electrically connected to the b output component 902. When electrically connected to the rectifier object, the A output component 801 and the a output component 802 are connected in parallel, and the B output component 901 and the b output component 902 are connected in parallel and then connected to the rectifier object respectively.

[0063] The rectifier unit 500 is liquid-cooled, and the main body 700 is provided with a first main pipe 34 and a second main pipe 35.

The liquid inlet of the same column of rectifier units 500 can be respectively connected to the branch pipe 36 corresponding to the first main pipe 34 through pipelines, and the liquid outlet can be respectively connected to the branch pipe 36 corresponding to the second main pipe 35 through pipelines. In the case of a large number of rectifier units 500, the cooling efficiency of each rectifier unit 500 can also be ensured by providing the branch pipe 36. When connecting the water inlet and outlet pipes for external cooling, the water inlet pipe can be directly connected to the inlet end of the first main pipe 34, and the water outlet pipe can be directly connected to the outlet end of the second main pipe 35, which is convenient and quick.

[0064] Preferably, the processing system, the power supply system and each rectifier unit 500 are integrated on the main body 700. Specifically, the main body 700 is provided with a first cavity 701 and a second cavity 702. The rectifier unit includes at least two rectifier units 500. The rectifier units 500 are stacked in the first cavity 701. Such intensive placement can maximize the reduction of the spatial size of the first cavity 701. The processing system and the power supply system are arranged in the second cavity 702, that is, placed outside the first cavity 701, so that the internal circuits and components of the rectifier device are clearly arranged and not disordered. Furthermore, the second cavity 702 is located above the first cavity 701, which can improve the structural integrity of the rectifier device and further reduce the floor space and space occupied by the rectifier device.

[0065] In another preferred embodiment, Figures 3 to 14 As shown, the rectifier stand-alone 500 includes a power module 200, a control module 100, a rectifier module 300, a commutation function module 400, and a first radiator 2 and a second radiator 3 arranged side by side and at intervals.

The power module 200 is electrically connected to the control module 100, the rectifier module 300 and the commutation function module 400 respectively. The control module 100 is communicated with the rectifier module 300 and the commutation function module 400 respectively. The rectifier module 300 is used to generate an output voltage between the first radiator 2 and the second radiator 3;

[0067] The rectifier stand-alone 500 of the present invention is provided with a rectifier module 300, a commutation function module 400, a first output conductor 4 and a second output conductor 5, and the power module 200, the control module 100, the rectifier module 300 and the commutation function module 400 are integrated and arranged on the first heat sink 2 and the second heat sink 3, and the control module 100 is respectively communicated and connected with the rectifier module 300 and the commutation function module 400, and the first output conductor 4 and the second output conductor 5 are respectively electrically connected with the commutation function module 400, so that the output obtained by rectification can be output through the first output conductor 4 and the second output conductor 5, and the commutation function module 400 is controlled by the control module 100, so that the commutation output can be realized, without manual assistance, and the degree of automation is high;

[0068] The rectifier of the present invention integrates the rectifier module 300 and the commutation function module 400 on the first heat sink 2 and the second heat sink 3 to realize an integrated layout. There is no need to set up a commutation device independent of the rectifier, which can greatly reduce the required layout space. Compared with the commutation device independent of the rectifier, the number of parts can be greatly reduced, thereby greatly reducing the manufacturing and use costs of the equipment. It can solve the problems of large occupied space, high cost and low efficiency of the existing rectifier using manual disassembly and assembly commutation and external mechanical commutation device to realize positive and negative electrode commutation.

The management unit 37 is preset with a control program to control the start, stop and operation of each rectifier unit 500. The user can use different control programs by using different management units 37 without replacing the PLC unit 39, thereby saving the use cost. Each rectifier unit 500 is respectively connected to the conversion circuit board 38 for communication, and then connected to the PLC unit 39 through the conversion circuit board 38. This simplifies the interface setting of the PLC unit 39 and avoids the complexity of the PLC unit 39 access structure due to the large number of rectifier units 500. The conversion circuit board 38 is used to receive the commutation command of the PLC unit 39 and send it to each rectifier unit 500.

The flow direction of the current in the type A synchronization module 12 and the type B synchronization module 13 is opposite, which can be achieved by changing the structural design of the synchronization module including the pin connection position. This is a conventional technical means in this field and will not be described in detail here; the number of synchronization modules in each of the above-mentioned synchronization module groups is specifically set according to the load current size of the rectifier unit. In this embodiment, the number of synchronization modules in each synchronization module group is two, and the positive and negative current ratio of the synchronization module can be up to 1:3;

[0075] The first end of the first synchronization module group 8 and the first end of the fourth synchronization module group 11 are electrically connected to the first output conductor 4, respectively, and the first end of the second synchronization module group 9 and the first end of the third synchronization module group 10 are electrically connected to the second output conductor 5, respectively; the second end of the first synchronization module group 8 and the second end of the second synchronization module group 9 are both electrically connected to the first heat sink 2, and the second end of the third synchronization module group 10 and the second end of the fourth synchronization module group 11 are both electrically connected to the second heat sink 3, so that the heat sink, the synchronization module and the corresponding output conductor can form a circuit;

[0076] The first driving module and the second driving module are respectively connected to the control module 100 for communication, and at the same time, the first driving module and the second driving module are respectively electrically connected to the power module 200; and the first driving module is respectively connected to the first synchronization module group 8 and the third synchronization module group 10 for communication, and the second driving module is respectively connected to the second synchronization module group 9 and the fourth synchronization module group 11 for communication;

[0077] After the control module 100 receives the first reversing instruction from the outside, it controls the first drive module to start and the second drive module to shut down, and the first drive module synchronously drives the first synchronization module group 8 and the third synchronization module group 10; after the control module 100 receives the second reversing instruction from the outside, it controls the second drive module to start and the first drive module to shut down, and the second drive module synchronously drives the second synchronization module group 9 and the fourth synchronization module group 11, that is, the first reversing instruction and the second reversing instruction are reversing instructions for each other.

[0078] In the rectifier stand-alone of the present embodiment, the first synchronization module group 8 and the second synchronization module group 9 are integrated and arranged on the surface of the first heat sink 2, and the third synchronization module group 10 and the fourth synchronization module group 11 are integrated and arranged on the surface of the second heat sink 3. The structure is compact, and the rectifier shape can be prevented from being excessively enlarged due to the addition of the reversing function module 400. The first synchronization module group 8 and the third synchronization module group 10 both include the same number of type A synchronization modules 12, and the second synchronization module group 9 and the fourth synchronization module group 11 both include the same number of type B synchronization modules 13. The same number ensures output stability and current sharing. The input direction of the type A synchronization module 12 is the same as that of the type B synchronization module 13, and the output direction is opposite. The first end of the first synchronization module group 8 and the first end of the fourth synchronization module group 11 are respectively connected to the first output conductor 4. The first end of the second synchronization module group 9 and the first end of the third synchronization module group 10 are electrically connected to the second output conductor 5 respectively, the second end of the first synchronization module group 8 and the second end of the second synchronization module group 9 are both electrically connected to the first radiator 2, the second end of the third synchronization module group 10 and the second end of the fourth synchronization module group 11 are both electrically connected to the second radiator 3. When the control module 100 receives the first commutation instruction and the second commutation instruction which are commutation instructions to each other respectively, the control module 100 can control the first drive module and the second drive module to start accordingly, and then synchronously drive the first synchronization module group 8 and the third synchronization module group 10 or the second synchronization module group 9 and the fourth synchronization module group 11 accordingly, so that the first output conductor 4 and the second output conductor 5 can achieve commutation stable output.

[0079] In a preferred embodiment, the switching function module 400 also includes a first connector 14 and a second connector 15. The first end of the first synchronization module group 8 and the first end of the fourth synchronization module group 11 are electrically connected to the first output conductor 4 through the first connector 14, and the first end of the second synchronization module group 9 and the first end of the third synchronization module group 10 are electrically connected to the second output conductor 5 through the second connector 15. Specifically, the first connector 14 is electrically connected to the first synchronization module group 8, the fourth synchronization module group 11 and the first output conductor 4 after being detachably connected, and the second connector 15 is also electrically connected to the second synchronization module group 9, the third synchronization module group 10 and the second output conductor 5 after being detachably connected. Furthermore, each synchronization module in each synchronization module group is correspondingly provided with a temperature sensor 16. The temperature sensor 16 is communicatively connected to the control module. The temperature sensor 16 sends the monitored temperature information to the control module. When the temperature sensor 16 detects abnormal temperature information, the control module will issue a shutdown or other action instruction accordingly to avoid the burning of the rectifier unit. Among them, as Figure 4 and Figure 6 As shown, the temperature sensors 16 corresponding to the synchronization modules in the first and fourth synchronization module groups are respectively detachably connected to the first connecting piece 14, and the temperature sensors 16 corresponding to the synchronization modules in the second and third synchronization module groups are respectively detachably connected to the second connecting piece 15. Preferably, the temperature sensor 16 is preferably located directly above the synchronization module to be detected and can be closest to the synchronization module to be detected, thereby ensuring the timeliness and effectiveness of the detection.

[0080] Further preferably, the synchronization modules in the first synchronization module group 8 and the fourth synchronization module group 11 are respectively fixed on the upper side of the first radiator 2 and the second radiator 3, and the second synchronization module group 9 and the third synchronization module group 10 are respectively fixed on the lower side of the first radiator 2 and the second radiator 3, or, the synchronization modules in the first synchronization module group 8 and the fourth synchronization module group 11 are respectively fixed on the lower side of the first radiator 2 and the second radiator 3, and the second synchronization module group 9 and the third synchronization module group 10 are respectively fixed on the upper side of the first radiator 2 and the second radiator 3. In this way, the corresponding synchronization module groups electrically connected to the output conductors are designed to be located on the same side, which can facilitate the structural design of the first output conductor 4 and the second output conductor 5, shorten the structural length of the two, and reduce the material consumption. In this embodiment, the first driving module and the second driving module each include two synchronization module driving boards 17, and each synchronization module driving board 17 is respectively communicated with the synchronization module in one of the synchronization module groups to drive the synchronization module in the synchronization module group; in actual applications, such as Figure 4 and Figure 6As shown, the first connector 14 and the second connector 15 are preferably plate-shaped electrical conductors, the first driving module is arranged on the side of the first radiator 2 facing away from the second radiator 3, and the second driving module is arranged on the side of the second radiator 3 facing away from the first radiator 2, so that the first connector 14 and the second connector 15 can both be single-folded plates, and the first ends and output conductors of the corresponding synchronization modules are electrically connected at the same time through the single-folded plates, which not only has a simple structure but also can effectively ensure current sharing.

[0081] In order to fix the synchronization module on the upper and lower sides of the heat sink, in a specific embodiment, as Figure 8 As shown, the first radiator 2 and the second radiator 3 are both provided with extension parts 18 extending toward each other on their upper and lower sides, and the extension part 18 and the upper or lower side of the corresponding radiator together constitute a support part 1, and the synchronization module is fixedly connected to the corresponding support part 1, and the synchronization module realizes its electrical connection with the corresponding radiator through a fixed connection. This embodiment utilizes the upper and lower space of the radiator to avoid the situation in conventional design where only the synchronization modules can be arranged in sequence on the side of the radiator, which can greatly shorten the span size of the two ends of the radiator and greatly reduce the internal resistance of the radiator. The synchronization module is in direct contact with the radiator and has a higher heat dissipation efficiency. It should be noted that the radiator in this embodiment is provided with a water circulation channel inside, and is a water-cooled radiator.

[0082] For example, Figures 9 to 11As shown, the A-type and B-type synchronous modules in this embodiment both include a circuit board 19, a first output element and two second output elements 20 arranged in parallel. The first output element is symmetrically and parallelly provided with two rows of Mosfet chips 21, and the two rows of Mosfet chips 21 are spaced apart by a preset distance. The first output element includes a strip-shaped flat plate base 22, and the flat plate base 22 is provided with convex strips 23 within a preset distance along its long side direction. The second output elements 20 are alternately and symmetrically arranged on both sides of the first output element, and each of the second output elements 20 and one of the rows of Mosfet chips 21 is located on the same side of the first output element, and the Mosfet chips 21 in each row are electrically connected to the second output elements 20 on the same side, and the second output elements 20 are attached to the corresponding heat sink, and the circuit board 19 is provided with an inner through hole, and the circuit board 19 is stacked on the upper side of the second output element 20, and the two rows of Mosfet chips 21 pass through the inner through hole, and each Mosfet chip 21 is electrically connected to the circuit board 19. The synchronization module of this embodiment can form a symmetrical structure, which can effectively ensure the current equalization effect. The two second output elements 20 are bonded to the heat sink to guide and dissipate heat. On the one hand, sufficient heat dissipation area is provided. On the other hand, the second output element 20 is in direct contact with the heat sink, which can effectively improve the heat dissipation efficiency, have good heat dissipation performance, and can be suitable for large current carrying. The flat base 22 and the convex strip 23 are preferably integrally formed in a T-shape, which can reduce the processing cost and avoid the influence of processing technology differences on the conductive uniformity of the first output element. Furthermore, a second insulating plate 24 is provided below the first output element and bonded to the first output element. The other side of the second insulating plate 24 is bonded to the heat sink to avoid the current directly passing through the first output element and conducting with the heat sink. The stacked structure can improve the heat transfer efficiency and increase the heat dissipation area in direct contact with the heat sink, thereby improving the heat dissipation efficiency. The insulating plate is preferably a ceramic plate.

[0083] It should be noted that, in this embodiment, the synchronization module and the radiator are detachably connected, which is convenient for disassembly and replacement during maintenance, and a bolt connection is preferably used; the first end and the second end of each synchronization module group correspond to the collective name of the output end and the input end of each synchronization module in the synchronization module group. In this embodiment, the first end of each synchronization module group is the convex strip 23 of each synchronization module. Fig.11 The second end of the synchronization module group is the second output element 20 of each synchronization module, Fig.11 As shown in the figure as input terminal.

Figure 12 to Figure 14As shown, the transformer assembly 25 includes an annular magnetic core 251 and a coil 252 wound on the magnetic core 251. The central hole of the magnetic core 251 is penetrated by a conductive core 253 along its axial direction. Conductive plates 254 are respectively provided at both ends of the conductive core 253. The conductive plates 254 are fixed and electrically connected to the first heat sink 2 and the second heat sink 3, and after the conductive plates 254 are fixed and connected to the first heat sink 2 and the second heat sink 3, the central axis of the magnetic core 251 is perpendicular to the plane where the first heat sink 2 and the second heat sink 3 are located. In this way, the direction of the magnetic field generated by the coil 252 relative to the rectifier chassis 32 can be changed, so as to avoid the chassis 32 being located in an area with large magnetic flux, and to avoid a large number of magnetic lines of force penetrating the chassis 32 to generate eddy currents, thereby greatly reducing the heat generation and energy loss of the chassis 32. The transformer of this embodiment is mainly composed of the magnetic core 251, the conductive core 253 and the conductive plate 254, and has a simple structure and is easy to assemble.

A preset target current value is input to the control console 600, and the control console 600 sends a third instruction to the processing system of the rectifier device. After receiving the third instruction, the processing system evenly distributes the preset target current value to the master and each slave, so as to control the master and each slave to start in the steady-current mode;

[0091] When the commutation mode is started, a commutation instruction is input to the control console 600, and the control console 600 sends an execution instruction to the processing system of the rectifier device.
