[0036] 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.

[0037] like Figures 1 to 4As shown, a vertical rectifier device provided in this embodiment includes a box body 6, a first heat sink 1 and a second heat sink 2 are vertically spaced apart in the box body 6, at least one transformer assembly 3 is vertically spaced apart between the first heat sink 1 and the second heat sink 2, the first heat sink 1 is provided with a synchronization module 4 corresponding to the transformer assembly 3 and a drive board 5 of the synchronization module 4, the second heat sink 2 is provided with an input power unit 7 and a control module 8, the input power unit 7 is electrically connected to the control module 8 and the drive board 5 respectively, the drive board 5 is communicatively connected to the control module 8, the input power unit 7 is used to connect to an external power supply, the upper end of the first heat sink 1 is sleeved with a current Hall sensor 9 and then extends out of the box body 6 to serve as one of the output poles, and the upper end of the second heat sink 2 is sleeved with an inductor 10 and then extends out of the box body 6 to serve as the other output pole;

[0038] The synchronization module 4 is electrically connected to the first heat dissipation block 1 and the transformer assembly 3 corresponding thereto, respectively. The transformer assembly 3 is also electrically connected to the second heat dissipation block 2 .

[0039] The present invention provides a box body 6, and vertically provides a first heat sink 1 and a second heat sink 2 in the box body 6, and extends the upper end of the first heat sink 1 and the upper end of the second heat sink 2 out of the box body 6 as two output poles of the rectifier, so that the height of the output pole can be increased by relying on its own structure, directly meeting the access height requirement of the rectifier object with a certain height above the ground, without the need to raise the height of the output pole with the help of an external device, and is easy to use. It can solve the problem of inconvenience and high cost caused by the existing low-voltage and high-current rectifier device being placed on a separately provided cabinet due to the limitation of its own structure when facing a rectifier object with a certain height above the ground, and then connecting its output pole to the rectifier object;

[0040] And by setting the transformer assembly 3 between the first heat sink 1 and the second heat sink 2, and correspondingly arranging the synchronization module 4 and its drive board 5, the input power unit 7 and the control module 8 on the first heat sink 1 and the second heat sink 2, an integrated arrangement is achieved, the shape of the box 6 is reduced, and the vertical rectifier is compact and occupies a small space. Of course, in a preferred embodiment, a lifting base and / or rollers can be set at the bottom of the box 6 to facilitate the movement of the rectifier and adapt to rectifier objects of different heights.

[0041] It should be noted that the rectifier input power supply unit 7 of this embodiment includes an EMC power supply board 701 and a switching power supply unit 702 electrically connected to the EMC power supply board 701, the control module 8 and the EMC power supply board 701 are arranged on the side of the second heat sink 2 facing away from the first heat sink 1, the switching power supply unit 702 is arranged on the upper part of the box 6, and the switching power supply unit 702 is used to supply power to the drive board 5 corresponding to each synchronization module 4. The functions of these components are all conventional basic functions of the rectifier device, which are well known to those skilled in the art, so they are not repeated here. In this embodiment, an air switch 11 is also embedded in the outer side of the box 6, and the air switch 11 is electrically connected to the EMC power supply board 701, so that the external power supply can be easily connected through the air switch 11. The side panels of the box 6 are all detachably connected to facilitate the inspection and maintenance of the internal components of the rectifier. In this embodiment, epoxy insulation blocks 12 are specifically arranged at the bottom and sides of the first heat sink 1 and the second heat sink 2, and the epoxy insulation blocks 12 are connected to the box 6, so as to achieve reliable and stable fixation of the first heat sink 1 and the second heat sink 2.

[0042] In a preferred embodiment, a first output conductor 13 with one end electrically connected thereto is transversely disposed at the upper end of the first heat sink 1, a second output conductor 14 with one end electrically connected thereto is transversely disposed at the upper end of the second heat sink 2, the current Hall sensor 9 is sleeved on the first output conductor 13, the inductor 10 is sleeved on the second output conductor 14, and the other ends of the first output conductor 13 and the second output conductor 14 are both extended out of the box 6 to serve as the output pole of the rectifier. By arranging the transverse first output conductor 13 and the second output conductor 14, after the rectifier is brought close to the rectified object, it is convenient to directly connect the output pole to the rectified object;

[0043] In addition, since the existing rectifier usually uses one end of the first heat sink 1 and the second heat sink 2 as the output pole, and the first heat sink 1 and the second heat sink 2 are usually made of aluminum, aluminum is easily oxidized when exposed to the air for a long time, and the conductivity will decrease to varying degrees, affecting the rectification effect. Preferably, the first output conductor 13 and the second output conductor 14 are both made of copper, which is more resistant to corrosion and oxidation. In this embodiment, the first output conductor 13 and the second output conductor 14 are outputted through copper, and the conductivity can remain stable for a long time. Further preferably, the surface of the first output conductor 1315 and the second output conductor 14 is galvanized to further improve the corrosion resistance.

[0044] In another preferred embodiment, the synchronization module 4 is located on the side of the first heat sink 1 facing away from the transformer assembly 3. During the operation of the rectifier, the synchronization module 4 and the transformer assembly 3 are both major heat sources. The synchronization module 4 and the transformer assembly 3 are respectively located on both sides of the first heat sink 1 so that the two are arranged separately, which can avoid heat concentration, thereby facilitating the timely dissipation of the heat generated by the two through the first heat sink 1. In addition, when disassembling and assembling, the synchronization module 4 and the transformer assembly 3 are not prone to interference in the operating space, which is convenient for fault maintenance.

[0045] In another preferred embodiment, Figure 5 As shown, the transformer assembly 3 includes an annular magnetic core 301 and a coil 302 wound on the magnetic core 301. The central hole of the magnetic core 301 is penetrated by a conductive core 303 along its axial direction. Conductive plates 304 are respectively provided at both ends of the conductive core 303. The conductive plates 304 are respectively fixed and electrically connected to the first heat sink 1 and the second heat sink 2. The central axis of the magnetic core 301 is in the transverse direction. In this embodiment, the central axis of the magnetic core 301 is in the transverse direction, so that the coil 302 can be wound in the transverse direction. This method can change the direction of the magnetic field generated by the coil 302 relative to the box 6, avoid the box 6 being located in an area with a large magnetic flux, and avoid a large amount of magnetic lines of force penetrating the box 6 to generate eddy currents, thereby greatly reducing the heat generation and energy loss of the box 6.

[0046] Specifically, the conductive core 303 includes a first battery core 305 and a second battery core 306, the first battery core 305 and the second battery core 306 are insulated from each other, a gap can be set between the first battery core 305 and the second battery core 306 to achieve insulation, the gap value is preferably 1mm to 1.5mm, and the gap can be further filled with insulating glue to improve the insulation performance; the conductive plate 304 includes a first electric plate 307, a second electric plate 308, a third electric plate 309 and a fourth electric plate 310;

[0047] The two ends of the first battery cell 305 are electrically connected to the first battery board 307 and the second battery board 308 respectively, and the two ends of the second battery cell 306 are electrically connected to the third battery board 309 and the fourth battery board 310 respectively. The first battery board 307 and the fourth battery board 310 are respectively used to be electrically connected to the corresponding synchronization module 4, and the second battery board 308 and the third battery board 309 are respectively used to be electrically connected to the second radiator.

[0048] In this embodiment, when the coil 302 is connected to alternating current, the magnetic core 301 will generate alternating magnetic flux, and voltage or current will be induced in the first electric plate 307, the second electric plate 308, the third electric plate 309 and the fourth electric plate 310. The first electric plate 307, the first battery core 305 and the second electric plate 308 are electrically connected in sequence to form a circuit, and the third electric plate 309, the second battery core 306 and the fourth electric plate 310 are electrically connected in sequence to form another circuit. Preferably, the first battery core 305 and the second battery core 306 are made of aluminum, which is not easy to heat up after the inductor 10, and the cost is relatively lower than that of copper. Of course, copper and other inductors 10 can also be used. The cross-sections of the first battery core 305 and the second battery core 306 are preferably semicircular, so that the cross-sectional area can be maximized, allowing large current to pass.

[0049] Furthermore, the first heat dissipation block 1 is provided with A column and B column synchronization module groups side by side on the side facing away from the transformer assembly 3, the number of synchronization modules 4 in each column synchronization module group is the same as the number of transformer assemblies 3 and corresponds one to one, and the synchronization modules 4 in the same column are arranged at intervals along the vertical direction; the first electric plate 307 is electrically connected to the corresponding synchronization module 4 in column A, and the fourth electric plate 310 is electrically connected to the corresponding synchronization module 4 in column B. In this embodiment, two columns of synchronization module groups are arranged on the side facing away from the transformer assembly 3 of the first heat dissipation block 1 at the same time, which makes full use of the side space of the first heat dissipation block 1, integrates the synchronization module 4 with the transformer assembly 3, and does not increase the height of the first heat dissipation block 1 due to the addition of the transformer assembly 3, which greatly reduces the external dimensions of the rectifier.

[0050] Furthermore, the first electric board 307 is electrically connected to the corresponding synchronization module 4 through the first connector 15, and the fourth electric board 310 is electrically connected to the corresponding synchronization module 4 through the second connector 16; and the first connector 15 is detachably connected to the first electric board 307 and the corresponding synchronization module 4, respectively, and the second connector 16 is detachably connected to the fourth electric board 310 and the corresponding synchronization module 4, respectively. In this way, when a synchronization module 4 or a transformer assembly 3 fails, it is only necessary to disassemble the first connector 15 or the second connector 16 first, and then the failed synchronization module 4 or transformer assembly 3 can be directly disassembled, without the need to disassemble both at the same time, which is convenient for maintenance.

[0051] Specifically, the first connector 15 and the second connector 16 are both concave folding plates. The first connector 15 buckles its concave groove on one side of the first heat sink 1 on one side of the A column synchronization module 4 group, and the second connector 16 buckles its concave groove on the other side of the first heat sink 1 on one side of the B column synchronization module 4 group, which not only realizes the electrical connection between the synchronization module 4 and the transformer assembly 3, but also saves space by buckling the first heat sink 1 with the concave groove, avoiding increasing the size of the box 6. It should be noted that during installation, after the first connector 15 and the second connector 16 are buckled on the side of the first heat sink 1, they do not directly contact the first heat sink 1, and each folding plate maintains a distance from the first heat sink 1 to avoid contact short circuit.

[0052] A thermally conductive pad 17 is sandwiched between the folding plate on one side of the first connector 15 and the second connector 16 close to the transformer assembly 3 and the first heat sink 1, and an insulating pad 18 is sandwiched between the thermally conductive pad 17 and the first heat sink 1. By setting the thermally conductive pad 17, on the one hand, it is beneficial to the timely heat dissipation of the transformer assembly 3, and on the other hand, the net distance between the first heat sink 1 and the second heat sink 2 can be appropriately increased, so that a high-power transformer assembly 3 can be replaced according to actual use needs; the first connector 15 and the second connector 16 are preferably copper sheets with excellent conductive properties, which are convenient for folding and for increasing or decreasing the number of copper sheets according to the installation gap. The thermally conductive pad 17 can be an aluminum block, and the insulating pad 18 can be a ceramic sheet.

[0053] In another preferred embodiment, Figures 6 to 8 As shown, the synchronization module 4 includes a base plate 401, a circuit board 402 and an output element 403. The bottom side of the base plate 401 is electrically connected to the first heat sink 1, and the top side of the base plate 401 is in contact with the circuit board 402. The base plate 401 is provided with a first inner through hole 404, and the circuit board 402 is provided with a second inner through hole 405. The output element 403 includes a strip-shaped flat base 406, an insulating sheet 407 is provided below the flat base 406, and a raised convex strip 408 is provided in the middle of the flat base 406 along its long side direction. The convex strip 408 is used to connect the induced current of the transformer component 3. The flat base 406 is provided with a row of Mosfet chips 409 on both sides of the convex strip 408 along its long side direction. The Mosfet chips 409 are electrically connected to the circuit board 402 and the base plate 401, respectively, and the convex strip 408 is used to be electrically connected to the transformer component 3. Preferably, the Mosfet chips 409 on both sides of the convex strip 408 are arranged symmetrically, and the distance between two adjacent Mosfet chips 409 in each column is the same, so that the current sharing effect of the synchronization module 4 can be ensured.

[0054] In another preferred embodiment, Fig. 9As shown, a first channel 21 for the circulation of coolant is provided inside the first heat dissipation block 1, and a second channel 22 for the circulation of coolant is provided inside the second heat dissipation block 2. The first channel 21 is connected to the second channel 22. Specifically, the connection can be achieved through an elbow 19 and a pipeline, and the pipeline is connected out of the box 6 to connect to a water source;

[0055] The first channel 21 extends from one end of the first heat sink 1 in the height direction to the other end thereof and from one side of the first heat sink 1 in the width direction to the other side thereof, and / or the second channel 22 extends from one end of the second heat sink 2 in the height direction to the other end thereof and from one side of the second heat sink 2 in the width direction to the other side thereof, thereby ensuring uniform heat dissipation of the first heat sink 1 and the second heat sink 2.

[0056] In another preferred embodiment, Figure 3 As shown, each synchronization module 4 is correspondingly provided with a temperature sensor 20, and the temperature sensor 20 is communicatively connected with the control system. The temperature sensor 20 sends the monitored temperature information to the control system. When the temperature sensor 20 detects abnormal temperature information, the control system will issue a stop or other action instruction accordingly to avoid the rectifier from burning out.
