[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0036] The following will describe the embodiments of the present application in combination with Figures 1 to 4

[0037] According to the embodiments of the present application, a power supply device is provided, which comprises: a shell 1, the shell 1 has a containing cavity; at least two rectifier assemblies, which are arranged in the containing cavity, are arranged at intervals, and the directions of the planes in which the at least two rectifier assemblies are arranged are arranged at an angle.

[0038] ​​​​By setting at least two rectifier components, the output power of the power supply can be increased, and its adaptability is stronger. By setting the planes where at least two rectifier components are located at an angle, the footprint of the power supply can be reduced, and maintenance can be simplified by simply disassembling the housing 1 on the side where the rectifier component to be maintained is located.

[0039] like Figures 1-2 As shown, in one embodiment, the housing 1 consists of a rectangular frame and six plates, which are fixedly connected to the rectangular frame to form the housing 1, and the six plates enclose a receiving cavity. As a variant implementation, the housing 1 may also exclude the rectangular frame and consist only of the six plates. As another variant implementation, the housing 1 may include four or eight plates; no further limitations are imposed here.

[0040] like Figures 1-2 As shown, in one embodiment, two support members 6 are fixedly connected to the bottom of the rectangular frame, and the two support members 6 are arranged opposite to each other. The support members 6 are channel steel. By setting the support members 6, the rectangular frame can be lifted, thereby facilitating the fixing of the bottom plate. As an alternative implementation, four support members 6 can also be provided; no further restrictions are imposed here. As an alternative implementation, the support members 6 can also be steel columns, I-beams, or rigid structures made of other materials such as aluminum; no further restrictions are imposed here.

[0041] like Figures 3-4 As shown, in one embodiment, two rectifier components are provided, arranged opposite each other, i.e., the angle between the directions of the planes containing the two rectifier components is 180°. By arranging the two rectifier components opposite each other, the floor space can be minimized. As an alternative implementation, three rectifier components can also be provided, with the angle between the directions of the planes containing the three rectifier components being 120°, or four rectifier components can be provided, with the angle between the directions of the planes containing the four rectifier components being 90°. The number of rectifier components is determined according to actual needs, and no further restrictions are imposed here.

[0042] like Figures 3-4 As shown, in one embodiment, each rectifier assembly includes two rectifier modules 2, which are spaced apart along their respective planes. The two rectifier modules 2 are a main unit rectifier module and a sub-unit rectifier module, respectively; the main unit rectifier module is located below the housing 1, and the sub-unit rectifier module is located above the housing 1. By including two rectifier modules 2 in each rectifier assembly, the output power of the rectifier assembly can be increased. Alternatively, each rectifier assembly may include one or three rectifier modules 2; no particular limitation is made here. Another possible implementation is that the main unit rectifier module is located above the housing 1, and the sub-unit rectifier module is located below the housing 1.

[0043] In one embodiment, the two rectifier modules 2 of each rectifier assembly have different output powers. Specifically, the output power of the mother rectifier module is greater than that of the daughter rectifier module. By setting the output power of the two rectifier modules 2 to be different, multiple output powers can be provided, thereby adapting to different loads. As a variant implementation, the two rectifier modules 2 of each rectifier assembly may also have the same output power; no further restrictions are imposed here.

[0044] like Figures 3-4 As shown, in one embodiment, the rectifier module 2 includes: a rectifier mechanism 21 for rectifying alternating current into direct current; and a control unit 22 electrically connected to the rectifier mechanism 21 for controlling the output power of the rectifier mechanism 21. Further, the rectifier mechanism 21 includes a transformer 211, with its transmission end bent outwards. The rectifier mechanism 21 also includes a thyristor; the transformer 211 is a transformer; the control unit 22 is a controller; and the transmission end of the transformer 211 is a secondary copper plate. By bending the transmission end of the transformer 211 outwards, both transmission ends can be oriented to one side, facilitating connection to the control unit 22 and simplifying maintenance. Alternatively, the rectifier mechanism 21 may include a transformer and a diode, or it may include a transformer and a bridge rectifier; no further limitations are imposed here.

[0045] In one embodiment, the control components 22 of each rectifier module 2 are electrically connected to each other. By electrically connecting all the control components 22, unified control of the control components 22 can be achieved, thereby facilitating operation. As an alternative implementation, the control components 22 of each rectifier module 2 may not be electrically connected to each other, or the control components 22 of each group of rectifier components may be electrically connected, but the groups of rectifier components may not be electrically connected to each other; no further restrictions are imposed here.

[0046] like Figures 3-4 As shown, in one embodiment, the power supply device includes a heat sink 3 disposed within a receiving cavity, with rectifier components provided on two side walls of the heat sink 3. Specifically, the heat sink 3 is located in the middle of the receiving cavity, and the two rectifier components are respectively located on opposite sides of the heat sink 3; the heat sink 3 is a fan. By providing the heat sink 3, the temperature inside the housing 1 can be reduced, thereby improving the service life of the rectifier mechanism 21. As an alternative implementation, rectifier components may also be provided along three or four side walls of the heat sink 3. As an alternative implementation, the heat sink 3 may also be a liquid-cooled structure or other structures capable of reducing temperature; no further limitations are imposed here.

[0047] like Figure 2As shown, in one embodiment, the power supply device includes an input terminal 4 and an output terminal 5, and each rectifier module 2 is electrically connected to both the input terminal 4 and the output terminal 5. By electrically connecting each rectifier module 2 to both the input terminal 4 and the output terminal 5, it is more convenient to control all rectifier modules 2.

[0048] like Figure 2 As shown, in another embodiment, the power supply device includes an input terminal 4 and an output terminal 5. Each rectifier component is electrically connected to both the input terminal 4 and the output terminal 5, and the two rectifier modules 2 of each rectifier component are connected in sequence. By connecting the two rectifier modules 2 of each rectifier component before electrically connecting them to the input terminal 4 and the output terminal 5, the structure can be simplified, thereby facilitating operation.

[0049] like Figure 2 As shown, in one embodiment, the power supply device includes a closing element 7, which is electrically connected to the control element 22. The closing element 7 is a circuit breaker. By providing the closing element 7, the risk of electric shock due to improper operation by the operator can be prevented. As an alternative implementation, the closing element 7 can also be an air switch or other structures capable of switching the circuit on and off; no further limitations are imposed here.

[0050] In this embodiment, during the assembly of the power supply device, the rectifier module 2 and the heat sink 3 are first fixed in the receiving cavity by a rectangular frame, and then the six plates are fixedly connected to the rectangular frame in sequence to complete the assembly.
