[0035] Please refer to Figure 1A , 1B and 2, Figure 1A and 1B The illustrations show schematic diagrams of a server rack 10 according to an embodiment of the present invention from different perspectives. Figure 2 Draw Figure 1A A schematic diagram showing the separation of the server rack 10 cabinet 11 from the pipeline limiting device 100.
[0036] like Figure 1A , 1B As shown in Figure 2, the server rack 10 includes a rack body 11, at least one pipe (e.g., a first pipe 12A, a second pipe 12B, a third pipe 12C, and a fourth pipe 12D), and a pipe limiting device 100. The pipe can pass through the pipe limiting device 100, which can restrain and / or fix the relative position of the pipe to the rack body 11. In this embodiment, the pipe limiting device 100 is detachably connected to the rack body 11 to facilitate quick handling (e.g., disassembly or assembly) of the pipe. Since the length L1 of the pipe limiting device 100 along the Z-axis is much shorter than the length L2 of the rack body 11 along the Z-axis, disassembly and / or assembly of the pipe limiting device 100 becomes easier (the longer the length L1 of the pipe limiting device 100 along the Z-axis, the more difficult it is to disassemble and / or assemble the pipe limiting device 100).
[0037] Although not shown, at least one server may be placed inside cabinet 11. A coolant (not shown) may flow through pipes to absorb heat from the server inside cabinet 11. The low-temperature coolant may enter cabinet 11 through one or more of these pipes, absorb heat from the server inside cabinet 11, and then flow out of cabinet 11 through another or more of these pipes. The aforementioned coolant may be, for example, water or other types of liquid.
[0038] Please refer to Figure 3 , 4A ~4C, 5A~5C and 6, Figure 3 Draw Figure 2 A schematic diagram of the pipeline limiting device 100 from another perspective. Figures 4A-4C Draw Figure 2 The pipeline limiting device 100 is shown in exploded views from different angles. Figure 5A Draw Figure 2The front view of the pipeline limiting device 100 viewed along the -Z axis. Figure 5B Draw Figure 5A A cross-sectional view of the pipeline limiting device 100 along direction 5B-5B'. Figure 5C Draw Figure 5A A cross-sectional view of the pipeline limiting device 100 along direction 5C-5C', and Figure 6 Draw Figure 3 The unfolded view of the first limiting member 110.
[0039] like Figure 2 and 4A As shown in Figure 4C, the pipeline limiting device 100 includes a first limiting member 110, a second limiting member 120, at least one first fixing member 130, at least one second fixing member 140, and at least one third fixing member 150. The first limiting member 110 has at least one first limiting hole 110r. The second limiting member 120 has at least one second limiting hole 120r and is detachably fixed to the first limiting member 110. The first limiting hole 110r and the second limiting hole 120r partially overlap. The pipe can pass through the overlap area R1 (overlap area R1 is shown in Figure 5B) of the first limiting hole 110r and the second limiting hole 120r to be restrained by the pipeline limiting device 100.
[0040] like Figures 4A-4C As shown in Figure 5C, the first limiting member 110 has opposing first side surface 110s1 and second side surface 110s2, and the second limiting member 120 has opposing third side surface 120s1 and fourth side surface 120s2. When the first limiting member 110 and the second limiting member 120 are assembled, the second side surface 110s2 is closer to the third side surface 120s1 than the first side surface 110s1, and the fourth side surface 120s2 is closer to the first side surface 110s1 than the third side surface 120s1.
[0041] like Figure 4A As shown, the first limiting hole 110r extends to the first side surface 110s1 to form a first opening 110r1, allowing the pipe to enter or exit the first limiting hole 110r of the first limiting member 110 through the first opening 110r1. The second limiting hole 120r extends to the third side surface 120s1 to form a second opening 120r1, allowing the pipe to enter or exit the second limiting hole 120r of the second limiting member 120 through the second opening 120r1.
[0042] like Figure 4A , 5BAs shown in Figure 5C, in one embodiment, the first limiting hole 110r does not extend to the second side surface 110s2, so that the pipe is confined within the first limiting hole 110r and cannot disengage from the first limiting member 110 in the +X axis. Furthermore, the second limiting hole 120r does not extend to the fourth side surface 120s2, so that the pipe is confined within the second limiting hole 120r and cannot disengage from the second limiting member 120 in the -X axis. When the first limiting member 110 and the second limiting member 120 are engaged, the first limiting hole 110r and the second limiting hole 120r at least partially overlap to form an overlap area R1, within which the pipe can be confined.
[0043] like Figure 4B As shown, the first limiting member 110 includes an upper plate 111, at least one first side plate 112, and at least one second side plate 113. In this embodiment, there are, for example, two second side plates 113, which are respectively disposed on opposite sides of the upper plate 111. Furthermore, the upper plate 111 has the aforementioned first side surface 110s1, and the first side plate 112 has the aforementioned second side surface 110s2. The upper plate 111 also has a lower surface 111b, and the first side plate 112 and the second side plate 113 are connected to the lower surface 111b of the upper plate 111 and protrude relative to the lower surface 111.
[0044] like Figure 4B As shown, the second side panel 113 includes a first portion 1131 and a second portion 1132. The first portion 1131 is located on the same side as the first side panel 112, on the same side as the upper panel 111. The second portion 1132 intersects with the first portion 1131; for example, the included angle between the second portion 1132 and the first portion 1131 is 90 degrees, but it can be larger or smaller. In one embodiment, the upper panel 111, the first side panel 112, and the second side panel 113 may be perpendicular to each other. The first side panel 112 and the second side panel 113 partially overlap. For example, the first portion 1131 of the first side panel 112 and the second side panel 113 partially overlap. The first portion 1131 and the first side panel 112 abut against the cabinet 11. The length of the first portion 1131 along the Z-axis is longer than the length of the first side panel 112 along the Z-axis, thus increasing the stability of the first limiting member 110 against the cabinet 11. The first limiting member 110 can, for example, be integrally formed by bending a metal part, such as... Figure 4A and 4B As shown.
[0045] like Figure 4B As shown, the first portion 1131 and the first side plate 112 can be fixed to each other, for example, end 1131A of the first portion 1131 (end 1131A is shown in...) Figure 6The first part 1131 can be fixed to the first side plate 112 by at least one fastener, such as a rivet. Alternatively, the first part 1131 and the first side plate 112 can be welded, snapped, or glued together, etc. The embodiments of the present invention do not limit the fixing method of the first part 1131 and the first side plate 112.
[0046] like Figure 6 As shown in the unfolded view of the first limiting member 110, there is a fold line S1 between the second side plate 113 and the upper plate 111, wherein the second side plate 113 and the upper plate 111 can be folded relative to the fold line S1; there is a fold line S2 between the first part 1131 and the second part 1132, wherein the first part 1131 and the second part 1132 can be folded relative to the fold line S2; there is a fold line S3 between the upper plate 111 and the first side plate 112, wherein the upper plate 111 and the first side plate 112 can be folded relative to the fold line S3; and the end 1131A can be folded relative to the fold line S4. Figure 6 The first limiting member 110, when unfolded as shown, forms the following shape after folding: Figure 3 The first limiting component 110.
[0047] In one embodiment, at least two of the upper plate 111, the first side plate 112, and the second side plate 113 may be integrally formed. For example, a plate may be bent and / or stamped to form an integrally formed structure. In terms of material, the first limiting member 110 may be made of metal, such as cold-rolled hot-dip galvanized steel sheet (SGCC).
[0048] like Figure 4B As shown, the second limiting member 120 includes an upper plate 121 and a third side plate 122. The upper plate 121 has the aforementioned third side surface 120s1, while the third side plate 122 has the aforementioned fourth side surface 120s2. The third side plate 122 is connected to and intersects with the upper plate 121. For example, the included angle between the third side plate 122 and the upper plate 121 is, for example, 90 degrees, but it can also be larger or smaller.
[0049] In one embodiment, the upper plate 121 and the third side plate 122 may be an integrally formed structure. For example, a plate may be bent and / or stamped to form an integrally formed structure. In terms of material, the second limiting member 120 may be made of metal, such as cold-rolled hot-dip galvanized steel sheet.
[0050] like Figure 2 and 4AAs shown in ~4C, the first fixing member 130 is detachably connected to the first limiting member 110 and is used to fix the first limiting member 110 to the cabinet 11. For example, the first limiting member 110 has at least one through hole 110a1. The first fixing member 130 has, for example, threads, and the cabinet 11 has at least one threaded hole 11a. The first fixing member 130 can pass through the through hole 110a1 and be screwed into the threaded hole 11a of the cabinet 11 to fix the relative position of the cabinet 11 and the first limiting member 110. Due to the detachability of the first fixing member 130, the first limiting member 110 can be quickly detached from the cabinet 11 and / or assembled to the cabinet 11. In this embodiment of the invention, the second limiting member 120 can be fixed to the cabinet 11 using the first fixing member 130, so that when the first limiting member 110 fixes the pipe, the pipe can be more secure and will not wobble.
[0051] like Figures 4A-4C As shown, the second fixing member 140 is detachably connected to the third fixing member 150 to fix the relative positions of the first limiting member 110 and the second limiting member 120. For example, the first limiting member 110 also has at least one fixing hole 110a2, and the second limiting member 120 has at least one through hole 120a, for example, the through hole 120a is formed in the upper plate 121. The second fixing member 140 is, for example, a rotatable fixing member that can be restrained in the through hole 120a of the second limiting member 120. For example, the second fixing member 140 is rotatable relative to the upper plate 121 but does not easily disengage along the Z-axis. The third fixing member 150 can be disposed on the first limiting member 110, for example, the third fixing member 150 can be riveted to the first limiting member 110. The aforementioned second fixing member 140 has a fastening pin 141 that can pass through the through hole 120a and the fixing hole 110a2 and be fixed to the third fixing member 150. The fastening pin 141 of the second fixing member 140 and the third fixing member 150 are, for example, in a tightly fitted state, preventing relative movement between the first limiting member 110 and the second limiting member 120. The rotatable fixing member design allows for easy disassembly of the two limiting members during assembly. The detachability of the second fixing member 140 relative to the third fixing member 150 allows for quick separation and / or connection of the first limiting member 110 and the second limiting member 120.
[0052] In one embodiment, the second fastener 140 is, for example, a rotatable screw (e.g., one that can be turned by hand) having threads (e.g., fastening pin 141 has threads), and the third fastener 150 is, for example, a nut. The second fastener 140 can pass through the through hole 120a and the fixing hole 110a2 and be screwed onto the third fastener 150 to fix the relative position of the first limiting member 110 and the second limiting member 120.
[0053] In this embodiment, the third fixing member 150 and the second fixing member 140 can form a fixing module. The first limiting member 110 and the second limiting member 120 are fixed to each other by at least one fixing module.
[0054] like Figures 4A-4C As shown, the first limiting member 110 also includes at least one first flange 114, which can be connected to the edge of the first limiting hole 110r and protrudes relative to the lower surface 111b of the upper plate 111 of the first limiting member 110. The first flange 114 acts as a reinforcing rib, which can increase the strength of the first limiting member 110. Similarly, the second limiting member 120 also includes at least one second flange 123, which can be connected to the edge of the second limiting hole 120r and protrudes relative to the upper surface 121u of the upper plate 121 of the second limiting member 120. The second flange 123 acts as a reinforcing rib, which can increase the strength of the second limiting member 120. Although not shown, the pipe can abut against the second flange 123. Taking the first pipe 12A as an example ( Figure 1A The pipe fitting 12A includes a pipe body 12A1 and a flange 12A2. The pipe body 12A1 can pass through the first limiting hole 110r and the second limiting hole 120r, while the flange 12A1 of the pipe fitting 12A can abut against the second flange 123 of the second limiting member 120, which can prevent the pipe fitting 12A from detaching from the pipe limiting device 100 in the -Z axis. The second pipe fitting 12B, the third pipe fitting 12C, and the fourth pipe fitting 12D have similar features to the first pipe fitting 12A, which will not be described in detail here. The pipe limiting device of this embodiment of the invention only has two components (i.e., the first limiting member 110 and the second limiting member 120) to fix the pipe fitting, thereby achieving the purpose of restricting the movement of the pipe fitting in the XY plane, and the design is simple.
[0055] As described above, this utility model provides a conduit limiting device and a server rack using the same. The conduit limiting device is adapted to be detachably connected to the server rack housing. In one embodiment, the conduit limiting device includes at least two components, each component having a limiting hole. When these components are combined, the limiting holes of these components at least partially overlap, allowing a conduit to pass through the overlap area and be restrained within the overlap area. In one embodiment, one of these components is detachably connected to the server rack housing and / or these components are detachably connected to each other, thus the conduit limiting device can be quickly assembled to the housing and / or quickly disassembled from the housing.
[0056] In summary, although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the scope of protection defined in the patent application.
