[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1-5 As shown, this utility model discloses a network cabinet expansion structure, including:

[0028] Main cabinet 1, the main cabinet 1 includes a main frame 11;

[0029] At least one expansion cabinet 2, the expansion cabinet 2 including an external frame 21, an RPDU mounting plate 22 and a manifold mounting plate 23, the external frame 21 being disposed on one side of the main frame 11 along its length, and the external frame 21 being detachably connected to the main frame 11; a first connection hole 211 is provided on the side of the external frame 21 connected to the main frame 11, and a second connection hole 212 is provided on the side of the external frame 21 away from the main frame 11; side plates 28 are provided on both sides of the external frame 21 along its width, the RPDU mounting plate 22 and the manifold mounting plate 23 being disposed on the side plates 28, and the RPDU mounting plate 22 and the manifold mounting plate 23 being disposed opposite to each other; a first top plate 24 is provided on the top of the external frame 21, and a first bottom plate 25 is provided on the bottom of the external frame 21, both the first top plate 24 and the first bottom plate 25 being provided with cable holes 26.

[0030] The expansion structure in this utility model is based on the existing main cabinet 1 structure. The main frame 11 serves as the supporting structure of the main cabinet 1, connecting the expansion cabinet 2 to the main frame 11. Specifically, the external frame 21 serves as the main structure of the expansion cabinet 2, and is installed on one side of the main frame 11. Side panels 28 are provided on both sides of the expansion cabinet 2, and RPDU mounting plates 22 and manifold mounting plates 23 are respectively installed on the side panels 28 for subsequent layout and installation of RPDUs and manifolds. The RPDU is a remote power distribution unit used to control and manage the network equipment for data center power, facilitating power supply for subsequent expansion modules. The manifold inside the expansion cabinet 2 includes a distributor and a collector, which, as a liquid cooling system, evenly distributes the low-temperature coolant output from the chiller (or external cooling source) to the cooling pipes of multiple devices requiring heat dissipation (such as servers, switches, GPUs, etc.) within the cabinet. As a preferred embodiment of this utility model, the RPDU mounting plate 22 and the manifold mounting plate 23 are installed opposite each other, effectively utilizing the internal space of the expansion cabinet 2. Furthermore, a first top plate 24 is provided at the top of the entire external frame 21, and a first bottom plate 25 is provided at the bottom, sealing the top and bottom of the external frame 21 to prevent dust and debris from entering the cabinet and protecting the equipment. Preferably, cable entry holes 26 are provided on the surfaces of both the first top plate 24 and the second top plate 13 for the subsequent introduction and exit of cables.

[0031] Furthermore, the expansion cabinet 2 in this invention can be further expanded in depth according to the dimensions of the internal installation modules. Specifically, multiple expansion cabinets 2 can be connected end-to-end with bolts through the first connecting holes 211 and the second connecting holes 212 on both sides of the outer frame 21 to meet installation requirements.

[0032] This invention expands the depth of the original cabinet 1 by installing an expansion cabinet 2 on one side of the main cabinet 1 without affecting the installation of other equipment. This solves the problem of insufficient upgrade space in communication cabinets, eliminating the need to replace the cabinet and reducing production costs. Furthermore, multiple expansion cabinets 2 can be connected to meet expansion needs at different depths. Additionally, the expansion cabinet 2 contains an RPDU mounting plate 22 and a manifold mounting plate 23, which can meet the needs of subsequent module upgrades.

[0033] Furthermore, a strip-shaped brush 27 is provided at the wire hole 26.

[0034] Specifically, the cable pass-through hole 26 is the same as the cable entry and exit point. A strip brush 27 is set at the cable pass-through hole 26. When the cable passes through the brush, the brush bristles can closely adhere to the surface of the cable and fill the gap between the cable and the opening, achieving the effect of "dust prevention while cable entry", which is superior to the traditional fixed hole design.

[0035] Furthermore, the height of the outer frame 21 is equal to the height of the main frame 11, and the width of the outer frame 21 is equal to the width of the main frame 11.

[0036] Specifically, during the actual installation process, the expansion cabinet 2 needs to be installed with a corresponding size to ensure that the size of the expansion cabinet 2 is equal to the size of the main cabinet 1, thus ensuring size compatibility.

[0037] Furthermore, the RPDU mounting plate 22 and the manifold mounting plate 23 are detachably connected to the side plate 28.

[0038] Specifically, the RPDU mounting plate 22 and the manifold mounting plate 23 can be adjusted to different heights within the expansion cabinet 2. Furthermore, during actual installation, the RPDU mounting plate 22 and the manifold mounting plate 23 can be removed as needed to increase the expansion space.

[0039] Furthermore, the main cabinet 1 also includes a mounting column 12, which is arranged along the height direction of the main frame 11 and is slidably connected to the main frame 11.

[0040] Specifically, in this invention, a PDU (Power Distribution Unit) can be installed between the mounting columns 12 inside the main cabinet 1 to adapt to the distribution and expansion of power for different modules. Secondly, the mounting columns 12 also ensure the supporting strength of the main cabinet 1. Preferably, the mounting columns 12 are slidably connected to the main frame 11, allowing for adjustment at different positions inside the main cabinet 1.

[0041] Furthermore, a second top plate 13 is provided at the top of the main frame 11, and a second bottom plate 14 is provided at the bottom of the main frame 11.

[0042] Similarly, the second top plate 13 and the second bottom plate 14 can protect the entire main cabinet 1. During the actual installation of the expansion cabinet 2, it is necessary to ensure that the first top plate 24 and the second top plate 13 are at the same horizontal height.

[0043] Furthermore, a cable management plate 15 is also provided inside the main frame 11, and the cable management plate 15 is arranged along the height direction of the main frame 11.

[0044] Specifically, the cable management board 15 in this utility model can be used as a special device for organizing, fixing and protecting cables, standardizing cable routing, reducing messy tangles, and improving the aesthetics, reliability and maintenance efficiency of the cabling system.

[0045] Furthermore, a grounding copper busbar 16 is also provided inside the main frame 11.

[0046] Specifically, in actual operation, after connecting the expansion cabinet 2 to the main cabinet 1, the entire network cabinet is grounded through the grounding copper busbar 16. Preferably, the grounding copper busbar 16 is made of high-purity copper (conductivity ≥97%), which has the characteristics of low impedance, corrosion resistance, and stable conductivity. Its core function is to provide a reliable grounding path for equipment and lines, ensuring personnel safety, stable equipment operation, and system lightning protection and interference resistance.

[0047] A network cabinet includes the network cabinet expansion structure described above.

[0048] In summary, this utility model introduces a network cabinet expansion structure and a network cabinet. By installing an expansion cabinet 2 on one side of the main cabinet 1, the depth of the original cabinet is expanded without affecting the installation of other equipment. This solves the problem of insufficient upgrade space in communication cabinets, eliminating the need to replace the cabinet and reducing production costs. Furthermore, multiple expansion cabinets 2 can be connected to meet expansion needs at different depths. Secondly, the expansion cabinet 2 is internally equipped with an RPDU mounting plate 22 and a manifold mounting plate 23, which can meet the needs of subsequent module upgrades.

[0049] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
