Technical field

The present disclosure relates to an expansion assembly for a data cabinet and a data cabinet system including a data cabinet and an expansion assembly.

Background technique

With the development of cloud computing and cloud storage industries, data storage and data exchange needs have attracted more and more attention. New data centers are constantly being built or existing data centers are being expanded to cope with the huge data processing needs. Data racks are typically arranged in data centers to house servers or data storage devices and associated wiring harnesses. Servers or data storage devices are connected to various terminal devices or power supplies via a large number of cables. In addition, working in a data center usually generates a lot of heat, so cooling systems are often required in the data racks, which in turn require additional space for cooling piping. Liquid-cooled servers are usually provided in the prior art to solve the above problems.

In the early stages of the construction of new data center infrastructure, the business and needs are often not very clear, and the server specifications and models are often uncertain. Once the needs are determined, the time left for the production and deployment of data cabinets is often very short, which cannot meet the needs of rapid development. Delivery requirements. However, in order to provide enough space for the installation of subsequent equipment, if a larger data cabinet is installed, it may cause a waste of valuable computer room space in the data center and increase the cost of the data cabinet itself. In addition, when an old data center is expanded, the data cabinet may need to fix additional wiring harnesses as its functions expand, or it may need to provide power supply and cooling functions for new servers or storage devices. However, the old data cabinet system The structural space may no longer be able to accommodate the setup and additional wiring harnesses of new servers, such as liquid-cooled servers.

Next, the expansion component 1 and the data cabinet system 100 according to the embodiment of the present disclosure are exemplarily described with reference to FIGS. 1 to 4 .

Referring to FIG. 1 , a data cabinet system 100 is shown in an assembled state according to one embodiment of the present disclosure. The data cabinet system 100 may have one data cabinet 1 . The data cabinet 1 may have a frame structure. The frame structure can have on each of its twelve edges, ie, on its twelve edges, side beams made, for example, of profiled sections, the side beams being connected to one another at the ends. When placed vertically, mounting strips are respectively provided on the sides of the data cabinet 1 for fixing and installing equipment, such as servers or switches. In FIG. 1 , the mounting strip may be a beam member connecting two vertically extending side beams. Therefore, the server may be supported on at least two beam members. However, it is also conceivable to provide substantially horizontally extending plate-like elements on at least two cross-beam elements, on which the servers or switches can then be placed. Due to the frame-shaped structure of the data cabinet 1 , servers or switches, for example, can be placed into the data cabinet 1 from any side of the data cabinet 1 and supported on corresponding beams or plates, as long as this side is in use. Not obscured by other data enclosures or coverings.

In Figure 1, an expansion component 2 can be configured on two opposite sides of the data cabinet 1. For the sake of clarity, the expansion component 2 in Figure 1 only has an expansion frame, that is to say, in all The expansion assembly 2 has not yet been provided with other components such as the mounting plate 5 and the adapter unit. The expansion component 2 can be detachably fixed on the side of the data cabinet 1 when in use, for example, detachably fixed on the side beam of the data cabinet 1 . However, it is also conceivable that the extension assembly 2 is placed only next to the side of the data cabinet 1 without being mechanically connected to the data cabinet 1 . In an embodiment not shown, the data cabinet may be configured with only a single expansion component.

Referring to Figure 2, a data cabinet 1 is shown together with an expansion assembly 2 shown separately on the left side of the data cabinet 1. The expansion module 2 on the right side of the data cabinet 1 can be designed identically, similarly, or differently. The following takes the extension component 2 on the left as an example for explanation. It goes without saying that the instructions related to this also apply to the extension 2 on the right. It can be seen that the extension component 2 has an extension frame. In particular, the width of the expansion frame of the expansion assembly 2 in the X direction and the height in the Z direction can be adapted to the width of the data cabinet 1 in the X direction and the height in the Z direction, so that in the expansion assembly 2 When configured in the data cabinet 1, a beautiful and unified appearance is achieved. It can also be seen in FIG. 2 that the extension frame of the extension assembly 2 has mutually opposite first frame plates 15 extending in the height direction or in the Z direction and in the width direction or in the X direction. Second frame plates 16 extend opposite each other, each second frame plate 16 connecting two first frame plates 15 to each other. In the embodiment shown, extension component 2 is open. It is conceivable that the opening of the expansion module 2 facing away from the data cabinet 1 can be closed with a cover plate (not shown).

In order to illustrate the extension component 2 more clearly, refer to FIG. 3 , which shows a partial perspective view of the extension component 2 . It can be seen that on each side of the extension frame of the extension assembly 2 , ie on each first frame plate 15 , two parallel vertically extending mounting bars 3 can be mounted. The mounting strip 3 has a plurality of first joint locations 4 that are consecutive in the height direction or in the Z direction, so that the mounting plate 5 can be selectively joined to the first joint locations 4 . Here, the mounting plate 5 can be selectively engaged at the first engagement point 4, which means that the engagement position of the mounting plate 5 in the height direction of the mounting bar 3 or in the Z direction is adjustable or can be adjusted. Selected. The mounting plate 5 can be joined to any first joining location 4 by means of hooks, or the mounting plate 5 can be joined to any first joining location 4 by means of fasteners. An adapter unit can then be provided on the mounting plate 5 , whereby the position of the adapter unit is indirectly adjustable in the height direction of the mounting strip 3 or in the Z direction. In the case of a multi-point positioning of the mounting plate 5 on the mounting strip 3 , the mounting plate 5 can be engaged at at least two matching first engagement points 4 by means of at least two hooks. In the embodiment shown, the mounting plate 5 is engaged at its four corners with two first engagement points 4 in each case of the two mounting bars 3 , for example by means of four screws. In the installed state, the mounting plate 5 can extend horizontally in the Y direction.

Each adapter unit can be mounted by means of at least one mounting plate 5 , for example by means of a single mounting plate 5 or by means of two or three mounting plates 5 , to an extension frame, in particular to a vertically extending portion of the extension frame. First frame plate 15.

Alternatively, the adapter unit can be engaged directly at the first engagement point 4 by means of a hook, or the adapter unit can be engaged directly at the first engagement point 4 by means of a fastener, for example a screw, so that no need for Mounting plate 5.

Referring to Figure 3, the mounting plate 5 has a plurality of second joint locations 6 distributed in the depth direction or in the Y direction. The adapter unit can selectively connect with at least one second joint location among the second joint locations. Engaged, so that the adapter unit can be selectively engaged on the mounting plate 5 along the mounting plate 5 in the depth direction or in the Y direction. Thus, the position of the adapter unit can be in two directions (ie in the height direction or Z direction along the mounting strip 3 and in the depth direction or Y direction along the mounting plate 5 ) Make adjustments. In this case, the adapter unit can be engaged at the second engagement point 6 by means of a hook, or the adapter unit can be engaged at the second engagement point 6 by means of a fastener.

Referring to Figure 3, one of the adaptation units may be a cooling fluid distribution unit 7 having a main inflow conduit 9 and a main outflow conduit 10 configured for A cooling cycle is formed for the equipment in the data cabinet, wherein the main inflow pipe 9 has a plurality of first fluid interfaces 13 distributed in the height direction or in the Z direction, the first fluid interfaces 13 being configured to For supplying cooling fluid to equipment in a data cabinet, the outflow main pipe 10 has a plurality of second fluid interfaces 14 distributed in its height direction or in the Z direction, and the second fluid interfaces 14 are configured to Used to collect the cooling fluid that has absorbed heat from the equipment in the data rack into an outflow main duct. One end of the first hose pipe 11 led out from the first fluid interface 13 is connected to the first fluid interface 13 , and the other end of the first hose pipe 11 is connected to the equipment in the data cabinet 1 . One end of the second hose pipe 12 leading out from the second fluid interface 14 is connected to the second fluid interface 14 , and the other end of the second hose pipe 12 is connected to the equipment in the data cabinet 1 . Due to the uncertainty in the position of the equipment located in the data cabinet 1 in the height direction of the data cabinet 1 or in the Z direction and the depth direction or in the Y direction, by adjusting the cooling fluid distribution unit 7 in the expansion assembly 2 The flexible positional adjustability enabled by the expanded position in the frame allows the position of the cooling fluid distribution unit 7 to be optimally adapted to the equipment in the data cabinet, and the first hose line 11 and the second hose line 12 bend as little as possible to avoid possible damage to the first hose pipe 11 and the second hose pipe 12, on the other hand, the required length of the first hose pipe 11 and the second hose pipe 12 as short as possible, which results in the dissipation of as little cooling power as possible during the transport of the cooling fluid. It should also be pointed out in FIG. 3 that the first hose duct 11 and the second hose duct 12 are independent of each other and that only the other end of the first hose duct 11 is visible in FIG. 3 , while the second hose duct 11 is visible in FIG. Said other end of the tube duct 12 is obscured by the first frame plate 15 of the extension frame 2 for reasons of viewing angle and is therefore not visible.

It can also be seen in Figure 3 that the main pipes as the inflow main pipe 9 and the outflow main pipe 10 are arranged on the left side of the expansion frame of the expansion assembly 2, so that the first hose pipe 11 and the second hose pipe The pipe 12 can extend in the interior space of the expansion frame from one side where the main pipes (the inflow main pipe 9 and the main outflow pipe 10 ) are located first towards the opposite side of the expansion frame and then in the middle of the expansion frame The space is curved in a circular arc in the direction of the devices of the data cabinet 1 and thus leads to the devices in the data cabinet 1 .

Optionally, the main pipes serving as the main inflow pipe 9 and the main outflow pipe 10 can be adjusted according to the positions of the cooling fluid input interface and the cooling fluid output interface of the equipment of the data cabinet 1, for example, they can be arranged on the expansion frame of the expansion assembly 2 the right side of.

In the embodiment shown in FIGS. 3 and 4 , both the main inflow pipe 9 and the main outflow pipe 10 are arranged on the same side of the extension assembly 2 , so that the main pipes (the main inflow pipe 9 and the main outflow pipe 10 ) are Both the first hose line 11 and the second hose line 12 project into the data cabinet 1 away from this side in the intermediate space of the extension frame of the extension assembly. Referring to FIG. 4 , it can be seen that a power distribution unit 8 is provided on the other side opposite the cooling fluid distribution unit 7 . The power distribution unit 8 can be disposed on the opposite side of the expansion frame of the expansion assembly 2 in a similar manner to the cooling fluid distribution unit 7 , and thus enables flexible position adjustability, which will not be described in detail here. . Additionally, a spacer can be provided between the cooling fluid distribution unit 7 and the power supply distribution unit 8 .

The power distribution unit 8 can be configured as a plug strip, which includes a plurality of side-by-side jack groups. For example, each jack group can have three jacks, and each jack group can be used to insert a plug with three pins.

In addition to the embodiments shown above, in some non-shown embodiments, the cooling fluid input interface or the cooling fluid output interface of the equipment in the data cabinet 1 is respectively closer to two opposite sides of the expansion frame of the expansion assembly 2 . In this case, the main inflow duct 9 and the main outflow duct 10 of the cooling fluid distribution unit 7 can be respectively arranged on two opposite sides of the expansion frame. More specifically, if the cooling fluid input interface of the equipment in the data cabinet 1 is closer to the first side of the expansion frame, the input main pipe 9 of the cooling fluid distribution unit 7 can be arranged on the first side of the expansion frame opposite to the first side. On both sides, in this way, a suitable bending space can be provided for the first hose line 11 connecting the cooling fluid inlet to the main inflow line 9 and at the same time a short hose line length can be provided. In such an embodiment, the cooling fluid output interface of the equipment in the data cabinet 1 is closer to the second side of the expansion assembly 2, so the outflow main pipe 10 of the cooling fluid distribution unit 7 can be arranged on the side of the expansion frame opposite to the second side. placed on the first side. In such an embodiment, since the main ducts are arranged on two opposite sides of the extension assembly 2, the power distribution unit may not be provided. However, it is also conceivable that the power supply distribution unit 8 can be arranged above the cooling fluid distribution unit 7 and be separated from the cooling fluid distribution unit 7 by a spacer.

In addition to the embodiments shown above, in some not-shown embodiments, a cable tie board or a cable management trough may be provided in the extension assembly 2 , thereby fixing and organizing the wire harness exposed in the data cabinet 1 .

In some embodiments, the expansion components and expandable data cabinet system of the present disclosure may have some or all of the following advantages, but are not limited to:
