Description

Technical Field

[0001] This invention belongs to the field of control cabinet technology, specifically relating to a data center liquid-cooled distribution unit mounting cabinet. Background Technology

[0002] With the continuous increase in data center computing density, liquid cooling technology has become the mainstream solution for addressing the heat dissipation problems of high-heat-density servers. Among these technologies, the Coolant Distribution Unit (CDU) control cabinet, as the core hub of the liquid cooling system, is showing a trend towards compactness and high power density. To save on-site space in the server room and achieve modular management, existing control cabinets are gradually evolving towards a "rackable" structure, meaning they are directly integrated into the server rack array.

[0003] However, due to the aforementioned development needs, the internal space of the control cabinet has been significantly reduced. This miniaturization design places more stringent requirements on the flow channel layout, component selection, and structural arrangement of the internal liquid cooling distribution unit. On the other hand, the limited internal space restricts the operator's work area, resulting in insufficient reserved space for pipeline interfaces, electrical components, and maintenance channels. This seriously affects the maintainability of the entire machine in the later stages, such as the convenience of daily inspections, troubleshooting, and modular replacement. Summary of the Invention

[0004] This invention provides a data center liquid-cooled distribution unit mounting cabinet, which aims to solve the problems of difficult internal layout and poor maintainability caused by the miniaturization and in-line development of control cabinets in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a data center liquid-cooled distribution unit installation cabinet, comprising: The cabinet has doors installed on both its front and rear sides for opening. The front-rear direction of the cabinet is defined as the first direction, and the left-right direction of the cabinet is defined as the second direction. The basic installation area is located inside the cabinet and in the lower half of the cabinet. The control and installation area is located inside the cabinet and in the upper part of the cabinet. The control and installation area includes a control area and a debugging area arranged sequentially from front to back. The control cabinet, which rotates vertically inside the control area, is used to install the electrical control module; The control cabinet has a first working position and a second working position inside the cabinet. In the first working position, the control cabinet rotates until its length direction is parallel to the left and right direction of the cabinet. In the second working position, the control cabinet rotates until its length direction is parallel to the front and back direction of the cabinet, so that there is an adjustment space between the side of the control cabinet and the left and right side walls of the control area, so as to facilitate maintenance personnel to adjust and maintain the debugging area.

[0006] In one possible implementation, along the thickness direction of the control cabinet, the corresponding hinge axis on the control cabinet is offset relative to the thickness centerline of the control cabinet, and the distance between the hinge axis and the two sides of the control cabinet along the thickness direction is not equal.

[0007] In one possible implementation, the front half of the debugging area is provided with a clearance area and an installation area along the second direction. The clearance area is used to prevent the control cabinet from rotating, and the installation area is used to install the components to be maintained.

[0008] In one possible implementation, the hinge axis on the control cabinet passes through the center of gravity of the control cabinet along its length.

[0009] In one possible implementation, the bottom of the control cabinet is provided with a plurality of cable-passing holes, and along the length of the control cabinet, the plurality of cable-passing holes are located on the same side of the hinge axis on the control cabinet.

[0010] In one possible implementation, a support frame for supporting the control cabinet is fixedly installed inside the cabinet, and the bottom of the control cabinet is hinged to the side of the support frame. When the control cabinet rotates from the first working position to the second working position, the projection of the plurality of wire holes along the vertical direction is always located outside the support frame.

[0011] In one possible implementation, a support rail for supporting the control cabinet is fixedly installed on the top of the support frame. The support rail is provided with fixing holes for fixing the control cabinet. The bottom of the control cabinet is provided with a through hole. When the control cabinet is rotated to a position where its length direction is aligned with the second direction, the fixing holes on the support rail coincide with the axis of the through hole at the bottom of the control cabinet.

[0012] In one possible implementation, the hinge axis of the control cabinet is located at the center of the support frame along a first direction.

[0013] In one possible implementation, the cabinet includes: There are multiple uprights, and the door panel is hinged to the uprights; A side plate is fixedly installed between two columns spaced apart along a first direction, wherein the thickness of the side plate along a second direction is less than the thickness of the columns along the second direction.

[0014] In one possible implementation, the column includes a main stiffening plate, and a first connecting plate and a second connecting plate are respectively bent on two opposite sides of the main stiffening plate. The first connecting plate is used to connect and fix the side plate, and the second connecting plate is used to connect and fix the door panel. The width of the first connecting plate is smaller than the width of the second connecting plate.

[0015] The solution presented in this application embodiment, compared with the prior art, provides a data center liquid-cooled distribution unit installation cabinet, which has an overall rectangular cabinet structure. The front-to-back direction of the cabinet is defined as the first direction, i.e., the arrangement direction of the front and rear door panels; the left-to-right direction of the cabinet is defined as the second direction, perpendicular to the first direction. The front and rear sides of the cabinet are respectively provided with independently openable door panels to facilitate internal operation from the front or rear.

[0016] The cabinet interior is divided into upper and lower sections. The basic installation area is located in the lower part of the cabinet, used to accommodate heavy or tall basic components of the liquid-cooled distribution unit, such as pumps, liquid storage tanks, and heat exchangers, utilizing the stability of the lower space to lower the overall center of gravity. The control and installation area is located in the upper part of the cabinet, divided into a commissioning area and a control area along the first direction. The control area is located on the side closer to the front door, and the commissioning area is located on the side closer to the rear door.

[0017] The control cabinet is rotatably mounted within the control area, with its central section pivotally connected to the middle of the cabinet in the left-right direction, forming a flip-up structure. The interior of the control cabinet houses the electrical control modules, including controllers, communication units, and power modules. During normal operation, the control cabinet is closed, with its front facing the operator for easy observation and operation of the human-machine interface. When maintenance or parameter adjustments are needed for the piping control components and liquid-cooling control components within the commissioning area, the operator can flip the control cabinet along the pivot axis, aligning its thickness in the second direction and revealing the commissioning area space behind it. This flipping operation allows the operator to directly adjust the piping valves, flow meters, temperature sensors, and control valve assemblies within the commissioning area from the front without removing the control cabinet.

[0018] Meanwhile, the cabinet features an openable rear door. When in-depth maintenance or modular replacement of components within the testing area is required, operators can open the rear door to directly access the testing area from the rear of the cabinet. This creates a bidirectional operating space within the testing area, with operation via the flip-up control cabinet at the front and via the rear door at the back, complementing each other.

[0019] Through the above structural layout, this embodiment achieves the organic integration of control zones and bidirectional maintenance channels within a compact cabinet space. On the one hand, the control cabinet is designed as a rotatable structure, so that it does not occupy additional operating space when closed, and provides a channel for front-side debugging when flipped, effectively solving the problem of insufficient operating area in a confined space. On the other hand, the layout of the debugging area, which is operable from both the front and rear, makes the arrangement of pipe interfaces and control components more flexible, no longer limited to a single operating direction, and facilitates the optimization of flow path and component arrangement within a limited space. Thus, this embodiment, while meeting the requirements of compact liquid cooling distribution units and in-line integration, significantly improves the convenience of daily inspection, fault diagnosis, and modular replacement, achieving a balance between high power density and high maintainability.

[0022] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0023] Please refer to the following: Figures 1 to 6The present invention will now describe the data center liquid-cooled distribution unit mounting cabinet. The data center liquid-cooled distribution unit mounting cabinet includes a cabinet body 1, a basic mounting area 2, a control mounting area 3, and a control cabinet 4. Doors 11 for opening the cabinet body 1 are installed on both the front and rear sides. The front-rear direction of the cabinet body 1 is defined as the first direction, and the left-right direction of the cabinet body 1 is defined as the second direction. The basic mounting area 2 is located inside the cabinet body 1 and in the lower half of the cabinet body 1. The control mounting area 3 is located inside the cabinet body 1 and in the upper half of the cabinet body 1. The control mounting area 3 includes a control area 32 and a debugging area 31 arranged sequentially from front to back. The control cabinet 4, vertically rotating inside the control area 32, is used to install the electrical control module.

[0024] The control cabinet 4 has a first working position and a second working position inside the cabinet 1. In the first working position, the control cabinet 4 is rotated so that its length direction is parallel to the left and right direction of the cabinet 1. In the second working position, the control cabinet 4 is rotated so that its length direction is parallel to the front and back direction of the cabinet 1, so that there is an adjustment space between the side of the control cabinet 4 and the left and right side walls of the control area 32, so that maintenance personnel can adjust and maintain the debugging area 31.

[0025] This embodiment provides a data center liquid-cooled distribution unit mounting cabinet. Compared with the prior art, this embodiment provides a data center liquid-cooled distribution unit mounting cabinet with an overall rectangular cabinet structure 1. The front-to-back direction of the cabinet 1 is defined as the first direction, that is, the arrangement direction of the front and rear door panels 11; the left-to-right direction of the cabinet 1 is defined as the second direction, which is perpendicular to the first direction. The front and rear sides of the cabinet 1 are respectively provided with independently openable door panels 11 to facilitate internal operation from the front or rear.

[0026] Inside cabinet 1, a vertically divided layout is adopted. The basic installation area 2 is located at the lower part of cabinet 1, used to accommodate heavy or tall basic components of the liquid-cooled distribution unit, such as pumps, liquid storage tanks, and heat exchangers, utilizing the stability of the lower space to lower the overall center of gravity. The control installation area 3 is located at the upper part of cabinet 1, divided into a commissioning area 31 and a control area 32 along the first direction. The control area 32 is located near the front door, and the commissioning area 31 is located near the rear door.

[0027] Specifically, in this embodiment, the control cabinet 4 is rotatably installed within the control area 32, with its central portion pivotally connected to the cabinet body 1, forming a structure that can be flipped around a vertical axis. The control cabinet 4 houses the electrical control modules, including a controller, communication unit, and power module. Under normal operating conditions, the control cabinet 4 is in a closed position, with its front facing the front of the cabinet body 1, facilitating observation and operation of the human-machine interface by the operator. When maintenance or parameter adjustment of the piping control components and liquid cooling control components inside the debugging area 31 is required, the operator can flip the control cabinet 4 along the hinge axis, aligning the thickness direction of the control cabinet 4 with the second direction, i.e., rotating the control cabinet 4 from the working position to the open position, thereby exposing the debugging area 31 space located behind it. Through this flipping operation, the operator can directly debug the piping valves, flow meters, temperature sensors, and control valve groups within the debugging area 31 from the front without disassembling the control cabinet 4.

[0028] Meanwhile, the rear of the cabinet 1 is equipped with an independently openable rear door panel 11. When in-depth maintenance or modular replacement of components inside the debugging area 31 is required, the operator can open the rear door panel 11 and directly access the debugging area 31 from the rear of the cabinet 1. Thus, the debugging area 31 forms a bidirectional operating space, with the front access accessed by flipping the control cabinet 4 and the rear access accessed by opening the rear door. The two complement each other and do not interfere with each other.

[0029] Through the above structural layout, this embodiment achieves the organic integration of control zones and bidirectional maintenance channels within the compact cabinet 1 space. On the one hand, the control cabinet 4 is designed with a flip-up structure, so that it does not occupy additional operating space when closed, and provides a channel for front-side debugging when flipped up, effectively solving the problem of limited operating area in a small space. On the other hand, the layout of the debugging area 31, which is operable from both the front and rear, means that the arrangement of pipe interfaces and control components is no longer limited to a single operating direction, providing greater design freedom for optimizing flow path and component arrangement. Thus, this embodiment, while meeting the requirements of compact liquid cooling distribution unit and in-line integration, significantly improves the convenience of daily inspection, fault diagnosis, and modular replacement, achieving a balance between high power density and high maintainability.

[0030] Specifically, in this embodiment, the control cabinet 4 is hinged on the cabinet 1 with its axis set in the vertical direction, so that when the control cabinet 4 is flipped, an operating space can be formed on the left and right sides of the operator.

[0031] Preferably, in this embodiment, see Figure 2The front door panel 11 of the cabinet 1, which is close to the control cabinet 4, is a double-door structure. It is hinged to the middle of the control cabinet 4 and installed inside the cabinet 1. This allows the control cabinet 4 to extend out of the cabinet 1 during rotation. At the same time, the double-door structure of the door panel 11 reduces the maintenance space requirements on the front of the cabinet 1 and is suitable for maintenance needs in smaller spaces.

[0032] In some embodiments, the control cabinet 4 described above can be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3 Along the thickness direction of control cabinet 4, the corresponding hinge axis on control cabinet 4 is offset relative to the thickness center line of control cabinet 4, and the distance between the hinge axis and the two sides of control cabinet 4 along the thickness direction is not equal.

[0033] The front-to-back direction of the control cabinet 4 when it is in the closed state is defined as its thickness direction, which is consistent with the first direction of the cabinet 1. Along the thickness direction of the control cabinet 4, the hinge axis is offset relative to the thickness centerline of the control cabinet 4, that is, the distance between the hinge axis and the two sides of the control cabinet 4 is not equal. As a specific implementation, the hinge axis is closer to one side of the control cabinet 4 and farther from the other side. For example, the distance between the hinge axis and the adjacent side is one-quarter to one-third of the overall thickness of the control cabinet 4, and the distance with the opposite side is two-thirds to three-quarters of the overall thickness of the control cabinet 4. By setting this offset ratio, the control cabinet 4 forms an asymmetrical radius of rotation when it is opened.

[0034] In actual operation, when operators need to maintain or adjust the pipeline control components and liquid cooling control components inside the debugging area 31, they can grasp the free edge of the control cabinet 4 and apply lateral pulling force to rotate the control cabinet 4 around the offset hinge axis. Due to the offset hinge axis, during the rotation, the free end of the control cabinet 4 swings away from the cabinet body 1, while its hinge end slightly retracts into the cabinet body 1, causing the control cabinet 4 to shift to one side. This offset movement creates a wider operating gap between the back of the control cabinet 4 and the front space inside the cabinet body 1, allowing operators to easily reach their hands and tools into this gap to perform debugging operations on the pipeline valves, flow meters, temperature sensors, and control valve groups within the debugging area 31.

[0035] Compared to a structure with the hinge axis centered, the offset structure in this embodiment increases the operating clearance between the back of the control cabinet 4 and the debugging area 31 by approximately 10% to 30% under the same cabinet 1 width. This structural design effectively avoids spatial interference between the electrical control module installed in the control cabinet 4 and the components in the debugging area 31, significantly improving the convenience of debugging from the front in a confined space.

[0036] In some embodiments, the cabinet 1 described above may adopt the following... Figure 2 The structure shown. See also Figure 2 The front half of the debugging area 31 is arranged along the second direction with a clearance area and an installation area. The clearance area is used to prevent the control cabinet from rotating, and the installation area is used to install components to be maintained. The debugging area 31 and the control area 32 are arranged along the first direction, with the control area 32 located on the side closer to the front door and the debugging area 31 located on the side closer to the rear door. Specifically, the hinge axis is set vertically, dividing the control area 32 where the control cabinet 4 is located into two side spaces along the second direction. The two side spaces are the clearance area and the installation area, respectively.

[0037] In one specific implementation, the control cabinet 4 adopts a unidirectional rotating structure, which rotates to open by a maximum of 90° around the hinge axis towards the side away from the installation area. Since the installation area is located on one side of the hinge axis, and the rotation direction of the control cabinet 4 is opposite to that of the installation area, the control cabinet 4 always maintains a state of avoiding the installation area during the rotation opening process, forming a stable avoidance relationship between the two.

[0038] Through the above layout, the debugging area 31 extends forward into the control area 32, making full use of the unused space on one side of the hinge axis within the control area 32. This expands the usable volume of the debugging area 31 without increasing the overall size of the cabinet 1. Simultaneously, the control cabinet 4 adopts a unidirectional 90° rotation structure, ensuring that it never overlaps with the installation area during full opening and closing. The control cabinet 4 will never rotate to the position of the installation area. This structural design not only ensures the smoothness of the control cabinet 4's rotation and opening but, more importantly, by limiting the rotation angle of the control cabinet 4 to a unidirectional 90°, allows the debugging area 31 to extend to the control area 32 to the maximum extent possible. This maximizes the volume of the debugging area 31 within the compact cabinet 1 space, further improving the overall space utilization and maintainability of the machine.

[0039] In some embodiments, the control cabinet 4 described above can be as follows: Figure 2 , Figure 3 The structure shown. See also... Figure 2 , Figure 3The hinge axis on control cabinet 4 passes through the center of gravity of control cabinet 4 along its length. The left-right direction of control cabinet 4 in its closed state is defined as its length direction, which coincides with the second direction of cabinet 1. Along the length direction of control cabinet 4 in its closed state, the hinge axis is located at the center of gravity of control cabinet 4. Specifically, the hinge axis coincides with the center of gravity line along the length direction of control cabinet 4, meaning the hinge axis passes through the center of gravity of control cabinet 4 along this direction. As a specific implementation, the electrical control modules installed inside control cabinet 4 include a controller, communication unit, and power supply module. The arrangement of each module along the left-right direction within control cabinet 4 is optimized according to its weight, so that the overall center of gravity of control cabinet 4 is located at or near the middle of its length direction in its closed state, and the hinge axis is correspondingly positioned at this center of gravity.

[0040] By setting the hinge axis at the center of gravity along the length of the control cabinet 4 when it is closed, the overall weight of the control cabinet 4 is evenly distributed along the axis of rotation during its rotational opening or closing process. Throughout the rotation, the center of gravity of the control cabinet 4 remains at the hinge axis. This structural design effectively prevents the cabinet 1 from tilting or deforming due to a shift in the center of gravity during the rotation of the control cabinet 4, ensuring the ease of operation and long-term stability of the control cabinet 4.

[0041] Specifically, in this embodiment, the center of gravity of the control cabinet 4 is located at the hinge axis on the control cabinet 4.

[0042] In some embodiments, the control cabinet 4 described above can be as follows: Figure 4 The structure shown. See also Figure 4 The bottom of the control cabinet 4 has multiple cable-passing holes 41, located on the same side of the hinge axis along the length of the control cabinet 4. These holes 41 are used for connecting cables between power control modules, as well as for communication and power cables between the control cabinet 4 and external components. Specifically, the length of the control cabinet 4 is the left-right direction when the control cabinet 4 is in the closed state. The hinge axis is vertically aligned, dividing the bottom of the control cabinet 4 into two regions along its length: the left side and the right side. The multiple cable-passing holes 41 are concentrated in one of these regions, rather than being scattered on both sides of the hinge axis.

[0043] With the above layout, all the cable holes 41 are concentrated on the same side of the hinge shaft axis, so that the cables connecting the electrical control modules inside the control cabinet 4 are all led out and converged from this side. When the control cabinet 4 rotates to open or close around the hinge shaft, the cables move with the control cabinet 4. Since the cable holes 41 are located on the same side of the hinge shaft axis, the cables only twist or swing in the same direction during the rotation of the control cabinet 4, and will not be entangled or pulled across the axis. This structural design effectively simplifies the cable routing path, avoids wear or breakage of cables due to repeated rotation, and facilitates cable bundling and fixing during production and assembly, significantly improving the neatness of the internal wiring and the long-term reliability of the machine.

[0044] Preferably, in this embodiment, since the wiring holes 41 are concentrated on the same side of the hinge axis along the length of the control cabinet 4, and the support frame 5 is not fully arranged along the second direction, the projection of the wiring holes 41 in the vertical direction when the control cabinet 4 is fully open is located outside the support frame 5. This ensures that the cables connecting the electrical control modules inside the control cabinet 4, after being led out from the wiring holes 41, always extend and move within the internal space of the cabinet 1. Specifically, during the opening or closing process of the control cabinet 4 rotating 90° around the hinge axis, the cables move together with the bottom of the control cabinet 4. Since the wiring holes 41 are located on the same side of the hinge axis, the cables only twist or swing in the same direction inside the cabinet 1, and will not extend outside the cabinet 1 or cross the hinge axis to become entangled. This structural design avoids interference between the cables and the external environment or other equipment during the rotation of the control cabinet 4, and at the same time prevents the cables from being accidentally pulled or damaged due to exposure, ensuring that the cables are always within the protection range of the cabinet 1, further improving the safety and wiring reliability of the entire machine.

[0045] In some embodiments, the cabinet 1 described above may adopt the following... Figure 1 , Figure 4 and Figure 5 The structure shown. See also... Figure 1 , Figure 4 and Figure 5The cabinet 1 contains a fixed support frame 5 for supporting the control cabinet 4. The bottom of the control cabinet 4 is hinged to the side of the support frame 5. When the control cabinet 4 rotates from the first working position to the second working position, the projection of the multiple wire holes 41 along the vertical direction is always located outside the support frame 5. The support frame 5 is a rectangular frame structure. The support frame 5 is not fully arranged along the second direction inside the cabinet 1, that is, the lateral span of the support frame 5 is less than the internal width of the cabinet 1. One side of it is fixedly connected to the side wall of the cabinet 1, and the other side is a free end, so that the support frame 5 only occupies part of the internal width space of the cabinet 1. The bottom of the control cabinet 4 is hinged to the side of the support frame 5. Specifically, a hinge seat is provided on the free end side of the support frame 5. The bottom of the control cabinet 4 is pivotally connected to the hinge seat through a hinge shaft, forming a central rotating structure that rotates around the vertical axis. Since the support frame 5 is not fully arranged along the second direction, the bottom hinge point of the control cabinet 4 is located on the side of the support frame 5, which makes the control cabinet 4 suspended on one side of the hinge point.

[0046] During the opening and closing process of the control cabinet 4 by rotating around the hinge axis, when it rotates to the point where its length direction is aligned with the second direction, the control cabinet 4 is in a fully closed state. At this time, the projections of the multiple wiring holes 41 at the bottom of the control cabinet 4 in the vertical direction are located outside the support frame 5. Since the support frame 5 does not extend completely into the entire second direction inside the cabinet 1, its outer area forms an unobstructed clearance space, and the projections of the wiring holes 41 fall precisely within this clearance space.

[0047] Through the above layout, the support frame 5 provides a stable bottom support and hinged mounting base for the control cabinet 4. Furthermore, because it is not fully arranged along the second direction, it saves space inside the cabinet 1. More importantly, when the control cabinet 4 is rotated to its fully open state, the projections of the multiple cable holes 41 in the vertical direction are located outside the support frame 5, ensuring that the space below the cable holes 41 is not obstructed by the support frame 5. This structural design provides ample clearance for cables connecting to the electrical control modules inside the control cabinet 4. Cables can be led vertically downwards from the cable holes 41 and move freely without interfering with the support frame 5. This avoids the cables being squeezed, bent, or worn due to obstruction by the support frame 5 during the rotation of the control cabinet 4, further improving the smoothness of cable routing and the reliability of long-term operation.

[0048] In some embodiments, the support frame 5 may be adopted as follows: Figure 5 The structure shown. See also Figure 5A support rail 6 for supporting the control cabinet 4 is fixedly installed on the top of the support frame 5. The support rail 6 has fixing holes for fixing the control cabinet 4, and the bottom of the control cabinet 4 has a through hole. When the control cabinet 4 is rotated to a position where its length direction is aligned with the second direction, the fixing holes on the support rail 6 coincide with the axis of the through hole at the bottom of the control cabinet 4. The support rail 6 is positioned along a first direction and is used to fix it to one side of the control cabinet 4. Specifically, the support rail 6 is installed on the upper surface of the support frame 5 and extends in the front-to-back direction. When the control cabinet 4 is in a fully closed state, the support rail 6 is located directly below one side of the bottom of the control cabinet 4, providing stable support to that side. The support rail 6 has fixing holes for fixing the control cabinet 4 to the support rail 6 when the control cabinet 4 is rotated to a position where its length direction is aligned with the second direction.

[0049] Correspondingly, the bottom of the control cabinet 4 is provided with a through hole corresponding to the fixing hole. When the control cabinet 4 is rotated and closed to the second direction along its length, the through hole on one side of the bottom of the control cabinet 4 is aligned vertically with the fixing hole on the support rail 6. The control cabinet 4 can be locked onto the support rail 6 by passing screws, bolts or pins through the through hole and the fixing hole in sequence.

[0050] In one specific implementation, the fixing holes are threaded holes, and the through holes are smooth holes. Screws are used to pass through the through holes from the bottom of the control cabinet 4 and then screw into the threaded holes to reliably fix the control cabinet 4. In another implementation, both the fixing holes and through holes are smooth holes, and bolts with nuts are used for fixing. Multiple fixing holes can be spaced at intervals along the first direction on the support rail 6, and multiple through holes are correspondingly provided on the bottom of the control cabinet 4 to enhance fixing stability.

[0051] With the above layout, the support rail 6 is set along the first direction and supported on one side of the control cabinet 4, providing the control cabinet 4 with precise closed positioning and stable unilateral load-bearing support. When the control cabinet 4 is in the fully closed state, the control cabinet 4 can be firmly locked onto the support rail 6 through the cooperation of the fixing hole and the through hole, effectively preventing the control cabinet 4 from rotating accidentally during transportation, vibration or daily use.

[0052] Meanwhile, since the support rail 6 only supports one side of the control cabinet 4, most of the bottom area of ​​the control cabinet 4 remains suspended, providing ample space for cable routing and movement through the bottom wiring hole 41. When maintenance is required, the lock can be released simply by removing the fasteners, allowing the control cabinet 4 to rotate and open freely. This structural design, while ensuring the operational stability of the control cabinet 4, also considers the provision of wiring space and the convenience of opening and maintenance, further improving the overall reliability, space utilization, and maintainability of the machine.

[0053] In some embodiments, the control cabinet 4 described above can be as follows: Figure 4The structure shown. See also Figure 4 The hinge axis of the control cabinet 4 is located at the center of the support frame 5 along the first direction. Specifically, the first direction is the front-to-back direction of the cabinet 1, that is, the arrangement direction of the front and rear door panels 11. The support frame 5 is fixedly installed inside the cabinet 1, and it has a front end and a rear end along the first direction. The projection of the hinge axis on the support frame 5 is located at the midpoint between the front end and the rear end of the support frame 5 along the first direction.

[0054] In one specific implementation, the support frame 5 has a rectangular frame structure, and its length along the first direction is adapted to the depth of the control area 32 inside the cabinet 1. The hinge seat at the bottom of the control cabinet 4 is located at the center of the support frame 5 along the first direction. The control cabinet 4 is pivotally connected to the hinge seat through a hinge shaft, forming a central rotating structure that rotates around a vertical axis. Since the axis of the hinge shaft is located at the center of the support frame 5, when the control cabinet 4 rotates around the hinge shaft, its weight is evenly transmitted to the front and rear ends of the support frame 5 through the hinge shaft, avoiding local overload or deformation of the support frame 5 due to uneven force distribution.

[0055] With the above layout, the hinge axis is located at the center of the support frame 5 along the first direction, so that the rotation center of the control cabinet 4 coincides with the geometric center of the support frame 5. When the control cabinet 4 is in the closed or open state, the weight of the control cabinet 4 and its internal electrical control module is symmetrically distributed on the front and rear sides of the support frame 5 through the hinge axis, making the stress state of the support frame 5 more balanced. This structural design effectively avoids problems such as deformation of the support frame 5, local stress concentration of the cabinet 1, or uneven wear of the hinge parts caused by eccentric loads, ensuring the long-term structural stability of the support frame 5 and the smoothness of the rotation of the control cabinet 4, further improving the reliability and service life of the whole machine.

[0056] In some embodiments, the cabinet 1 described above can be adopted as follows: Figure 6 The structure shown. See also Figure 6 The cabinet 1 includes uprights 12 and side panels 13. There are multiple uprights 12, and the door panel 11 is hinged to the uprights 12. The side panel 13 is fixedly installed between two uprights 12 spaced apart along a first direction. The thickness of the side panel 13 along a second direction is less than the thickness of the uprights 12 along the second direction. In other words, the uprights 12 protrude relative to the side panels 13 towards the interior or exterior of the cabinet 1, creating a significant thickness difference.

[0057] As a specific implementation method, the column 12 can be made of rectangular tube or C-shaped steel and its thickness along the second direction is large to ensure structural strength; the side plate 13 is made of sheet metal and its thickness is much smaller than that of the column 12 to reduce the weight of the whole machine and save internal space.

[0058] To meet the overall strength requirements of cabinet 1, the thickness of the upright 12 is designed to be much greater than the thickness of the side panel 13. Compared to the existing structure where the control cabinet 4 is hinged to the side wall of cabinet 1 on one side, in this embodiment, the control cabinet 4 adopts a central hinge structure at the top and bottom, with its hinge axis located at the center of the support frame 5 along the first direction. This structural layout satisfies the strength requirements of cabinet 1 while making more rational use of the internal space of cabinet 1.

[0059] Specifically, in the existing single-sided hinged structure, the control cabinet 4 rotates to open around one side. The overall width of the control cabinet 4 is limited by the gap between the two uprights 12 on the front side of the cabinet 1. If the width of the control cabinet 4 is greater than this gap, the control cabinet 4 will not be able to fit between the two uprights 12 in the closed state, or it will interfere with the uprights 12 when rotating to open. In this embodiment, since the control cabinet 4 adopts a central hinged structure and the hinge axis is located at the center of the support frame 5, when the control cabinet 4 rotates around the hinge axis, its two sides are symmetrically distributed on both sides of the hinge axis in the closed state. When the side of the control cabinet 4 rotates to the upright 12, there is still a certain clearance between the control cabinet 4 and the upright 12. Therefore, in designing the control cabinet 4, this application can set the width of the control cabinet 4 to be greater than the gap between the two uprights 12 on the front side of the cabinet 1, thereby accommodating a wider control cabinet 4 in a limited space and providing more layout space for the installation of the electrical control module.

[0060] Through the above structural design, this embodiment breaks through the limitation of the width of the control cabinet 4 by the traditional side hinge structure without increasing the overall size of the cabinet 1, realizes a fuller utilization of the internal space of the cabinet 1, and further improves the integration and space utilization of the whole machine.

[0061] In some embodiments, the aforementioned column 12 may be adopted as follows: Figure 6 The structure shown. See also Figure 6 The column 12 includes a main stiffening plate 121. A first connecting plate 122 and a second connecting plate 123 are respectively bent and installed on two opposite sides of the main stiffening plate 121. The first connecting plate 122 is used to connect and fix the side plate 13, and the second connecting plate 123 is used to connect and fix the door panel 11. The width of the first connecting plate 122 is smaller than the width of the second connecting plate 123. The first connecting plate 122 has a shorter extension length after bending from the edge of the main stiffening plate 121, while the second connecting plate 123 has a longer extension length after bending from the edge of the main stiffening plate 121. In one specific embodiment, the column 12 can be integrally bent from sheet metal, with the first connecting plate 122 and the second connecting plate 123 forming an approximately C-shaped cross-sectional structure together with the main stiffening plate 121.

[0062] With the above layout, the first connecting plate 122 is narrower, thus providing more clearance for the rotation of the control cabinet 4 inside the cabinet 1. At the same time, the second connecting plate 123 is wider, providing a wider hinge mounting surface for the door panel 11, ensuring the connection strength and hinge stability between the door panel 11 and the column 12.

[0063] Along the first direction, the column 12 is located on the side of the control cabinet 4 near the front of the cabinet body 1, close to the hinge axis. That is, the column 12 is positioned within the area between the hinge axis and the front door panel 11, making it easy for the side of the control cabinet 4 to interfere with the first connecting plate 122 on the column 12 during the opening or closing process around the hinge axis. In this structural layout, the design that the width of the first connecting plate 122 is smaller than the width of the second connecting plate 123 has significant technical implications. Because the first connecting plate 122 is narrower, the side plate 13 is closer to the main stiffener 121 after installation, reducing the protrusion of the column 12 towards the interior of the cabinet body 1. This provides more clearance for the side of the control cabinet 4, effectively preventing collisions or friction between the control cabinet 4 and the column 12 during rotation.

[0064] This structural design allows the control cabinet 4 to smoothly avoid the columns 12 and side panels 13 during rotation. Based on this structure, the width of the control cabinet 4 can be designed to be larger, even exceeding the gap between the two columns 12 on the front side of the cabinet 1. This allows for a wider control cabinet 4 to be accommodated in a limited space, providing more layout space for the installation of electrical control modules and further improving the utilization rate of the internal space of the cabinet 1 and the integration of the whole machine.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
