Description

Technical Field

[0001] This invention relates to the field of liquid-cooled distributor technology, and more specifically, to a liquid-cooled distributor and a liquid-cooled network cabinet. Background Technology

[0002] As data center computing density continues to increase, the power consumption of network servers, switches and other equipment has increased significantly. Traditional air cooling methods can no longer meet the heat dissipation needs of high-density equipment. Immersion and plate-type indirect liquid cooling technologies have gradually become mainstream. As the core distribution component of liquid-cooled network cabinets, the liquid cooling distributor plays a crucial role in evenly distributing the main cooling medium to the cooling pipes of each layer of equipment and collecting the return cooling medium. Its structural performance directly determines the overall heat dissipation efficiency, operational stability and maintenance convenience of the cabinet.

[0003] Traditional liquid distributors mostly adopt a fixed orifice flow distribution structure, with uniform flow resistance in each branch channel. This makes it impossible to adapt to the differentiated heat dissipation needs of different levels and power consumption devices in the cabinet. The supply of cooling medium to high-load devices is insufficient, and uneven flow in the branches leads to large temperature differences and high energy consumption in the overall heat dissipation of the cabinet. The fixed flow channel structure has poor flow resistance stability and is prone to flow deviation during long-term operation. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a liquid-cooled distributor and a liquid-cooled network cabinet.

[0005] The technical solution is as follows:

[0006] A liquid-cooled distributor includes a distributor body, the distributor body including a housing, the housing having an upward-opening insertion cavity, a sealing element being detachably installed at the insertion cavity, and the sealing element and the insertion cavity together forming a buffer cavity;

[0007] The seal has multiple flow-diverting chambers that communicate with the buffer chamber. The outer wall of the seal is provided with an inlet throttling pipe that communicates with the multiple flow-diverting chambers. Each flow-diverting chamber is connected to an adjustment component corresponding to the inlet throttling pipe. The adjustment component is used to make axial displacement in response to the change of pressure difference between the buffer chamber and the corresponding inlet throttling pipe, so as to adjust the flow rate of the corresponding inlet throttling pipe.

[0008] Furthermore, the bottom of the seal has a protrusion that mates with the insertion cavity, and a sealing ring is installed on the outer wall of the protrusion.

[0009] Furthermore, a through hole corresponding to the adjustment component is provided on the bottom wall of the protrusion. The adjustment component includes a mounting base, a sliding cavity is provided inside the mounting base, and an installation port connecting the through hole and the sliding cavity is provided on the bottom wall of the mounting base. An elastic diaphragm is installed at the installation port, and a valve core that cooperates with the liquid inlet throttling pipe is slidably installed in the sliding cavity. An extension column is provided on the bottom wall of the valve core, and a connector connected to the end of the extension column is installed at the axis of the elastic diaphragm.

[0010] A bracket is connected to the inner wall of the sliding cavity located below the valve core. A first spring is connected between the bottom wall of the bracket and the elastic diaphragm. The first spring is used to provide the elastic force to keep the elastic diaphragm pressed in the direction of the through hole.

[0011] Furthermore, the inner wall of the inlet throttling tube has an inner conical structure, and the end of the valve core has a conical stepped structure. The conical stepped structure at the end of the valve core and the inner conical structure of the inner wall of the inlet throttling tube cooperate to form an annular flow gap.

[0012] Furthermore, an annular groove is provided on the outer wall of the extension column, a metal plate is installed in the groove, and an electromagnet that cooperates with the metal plate is installed on the inner wall of the bracket.

[0013] Furthermore, an inlet pipe is detachably installed on the inlet throttling pipe, and a flow sensor is installed at the outlet end of the inlet pipe. The flow sensor is electrically connected to an electromagnet.

[0014] Furthermore, an inlet chamber is provided inside the shell on the side away from the buffer chamber. The top wall of the inlet chamber has two inlet channels that connect the buffer chamber and the inlet chamber. A supply pipe that communicates with the inlet chamber is connected to the bottom wall of the equipment cavity. The supply pipe is located between the two inlet channels.

[0015] Furthermore, a guide plate is connected to the liquid inlet channel, and the guide plate has an arc-shaped arched grid structure, wherein the direction of the arc arch is directly opposite to the direction of the liquid inlet channel.

[0016] Furthermore, rubber pressure rings are provided at both edges of the elastic diaphragm, and a fixing ring for fixing the elastic diaphragm is detachably installed on the bottom wall of the mounting port.

[0017] A liquid-cooled network cabinet includes a cabinet, with an equipment cavity for installing server equipment and an installation cavity for installing the aforementioned liquid-cooled distributor.

[0018] Based on the above description, the beneficial effects of the liquid-cooled distributor and liquid-cooled network cabinet of the present invention are as follows:

[0019] The modular structure, which allows for detachable connection between the seal and the housing, integrates multiple flow chambers and inlet throttling pipes within the seal. Each flow chamber is equipped with an independent adjustment component, ensuring that the flow regulation in each inlet throttling pipe is independent and does not interfere with each other. This allows for adaptive adjustment of the cooling medium flow rate in the corresponding inlet throttling pipe to accommodate the power consumption differences of different server devices within the rack. This avoids insufficient cooling medium supply for high-load equipment, uneven branch flow leading to large temperature differences and high energy consumption in the overall rack, and the risk of flow deviation during long-term operation.

[0020] By combining a metal plate, an electromagnet, and a flow sensor, adaptive flow regulation and electromagnetic positioning locking are linked. The flow sensor collects the temperature of the cooling medium at the outlet of the inlet pipe in real time after heat exchange. When the temperature of the cooling medium at the outlet of the inlet pipe is higher than the preset threshold, the electromagnet is activated. The electromagnet generates a magnetic field that attracts the metal plate, locking the valve core in the current position, so that the flow gap is always at the increased size after adjustment. When the temperature of the cooling medium at the outlet of the inlet pipe is lower than the preset threshold, the electromagnet is de-energized, and the valve core resumes the adaptive flow regulation function.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] The embodiments provided by the present invention will be described in detail below:

[0038] Example 1

[0039] like Figures 1 to 8 As shown, a liquid-cooled network cabinet includes a cabinet 100. The cabinet 100 has a device cavity 110 for installing server equipment and a mounting cavity 120. A liquid-cooled distributor and a liquid collector 300 are detachably installed in the mounting cavity 120. The output end of the liquid-cooled distributor is connected to an inlet pipe 310, and the input end of the liquid collector 300 is connected to a return pipe 320. The output end of the inlet pipe 310 and the input end of the return pipe 320 are detachably located on the input and output ends of the liquid-cooled plate, respectively. After the cooling medium exchanges heat with the heat-generating components in the equipment within the liquid-cooled plate, it is collected by the liquid collector 300 and returned to the CDU heat exchange unit for circulation. This is prior art and will not be described in detail here.

[0040] The liquid-cooled distributor includes a distributor body 200, which includes a housing 210. The housing 210 has an upward-opening insertion cavity 211. A seal 220 is detachably installed at the insertion cavity 211. The seal 220 and the insertion cavity 211 together form a buffer cavity 212.

[0041] The seal 220 has multiple flow-diverting chambers 222 that communicate with the buffer chamber 212. The outer wall of the seal 220 is provided with an inlet throttling pipe 223 that communicates with the multiple flow-diverting chambers 222. Each flow-diverting chamber 222 is connected to an adjustment component 230 corresponding to the inlet throttling pipe 223. The adjustment component 230 is used to perform axial displacement in response to the change in pressure difference between the buffer chamber 212 and the corresponding inlet throttling pipe 223, so as to adjust the flow rate of the corresponding inlet throttling pipe 223.

[0042] It should be noted that this embodiment adopts a split structure in which the sealing element 220 and the insertion cavity 211 of the housing 210 can be detachably matched. The multi-component flow chambers 222 and the liquid inlet throttling pipes 223 are integrated inside the sealing element 220. At the same time, each flow chamber 222 is independently equipped with an adjustment component 230, so that the flow adjustment in each liquid inlet throttling pipe 223 is independent and does not interfere with each other. Compared with the prior art, it can adaptively adjust the flow of the cooling medium in the corresponding liquid inlet throttling pipe 223 according to the power consumption difference of different server devices in the rack 100. This avoids the situation where the cooling medium supply of high load equipment is insufficient, the branch flow is uneven, resulting in a large temperature difference in the overall heat dissipation of the rack, high energy consumption, and flow deviation during long-term operation.

[0043] like Figure 5 As shown, the bottom of the seal 220 has a protrusion 221 that mates with the insertion cavity 211, and a sealing ring is installed on the outer wall of the protrusion 221.

[0044] It should be noted that the assembly structure is simple and the alignment is precise through the insertion of the protrusion 221 and the insertion cavity 211. This facilitates the disassembly and replacement of the seal 220 and subsequent maintenance, without the need to disassemble the main body of the distributor 200, thus reducing equipment operation and maintenance costs.

[0045] like Figure 6 and Figure 7 As shown, a through hole 224 corresponding to the adjustment component 230 is provided on the bottom wall of the protrusion 221. The adjustment component 230 includes a mounting base 231. A sliding cavity 2311 is provided inside the mounting base 231. An installation port communicating with the through hole 224 and the sliding cavity 2311 is provided on the bottom wall of the mounting base 231. An elastic diaphragm 232 is installed at the installation port. A valve core 233 that cooperates with the liquid inlet throttling pipe 223 is slidably installed in the sliding cavity 2311. An extension post 234 is provided on the bottom wall of the valve core 233. A connector 235 connected to the end of the extension post 234 is installed at the axis of the elastic diaphragm 232.

[0046] A bracket 237 is connected to the inner wall of the sliding cavity 2311 located below the valve core 233. A first spring 236 is connected between the bottom wall of the bracket 237 and the elastic diaphragm 232. The first spring 236 is used to provide elastic force to keep the elastic diaphragm 232 pressed in the direction of the through hole 224.

[0047] It should be noted that in this embodiment, the pressure connection between the buffer chamber 212 and the sliding chamber 2311 of the regulating component 230 is achieved through the through hole 224. Relying on the linkage of the elastic diaphragm 232, the first spring 236 and the valve core 233, a passive pressure sensing flow regulation mechanism is constructed. By setting the preload of the first spring 236, the elastic diaphragm 232 maintains its initial position when the pressure in the buffer chamber 212 and the liquid inlet throttling pipe 223 is in equilibrium, ensuring that the flow gap between the valve core 233 and the liquid inlet throttling pipe 223 is maintained at the design reference value. When the pressure in the liquid inlet throttling pipe 223 increases due to high load heat exchange of the downstream equipment, the pressure acts on the elastic diaphragm 232 and overcomes the preload of the first spring 236, pushing the valve core 233 to move axially to increase the flow gap and increase the liquid supply flow rate, so that it can adapt to the heat dissipation requirements of different power consumption devices.

[0048] The inner wall of the liquid inlet throttling pipe 223 has an inner cone structure, and the end of the valve core 233 has a conical stepped structure. The conical stepped structure at the end of the valve core 233 and the inner cone structure of the inner wall of the liquid inlet throttling pipe 223 cooperate to form an annular flow gap.

[0049] It should be noted that by combining the tapered stepped structure at the end of the valve core 233 with the inner tapered structure on the inner wall of the inlet throttling pipe 223, a gradually changing annular flow gap can be formed, which can achieve linear and continuous adjustment of the flow rate.

[0050] An annular groove is provided on the outer wall of the extension column 234, a metal plate 239 is installed in the groove, and an electromagnet 238 that cooperates with the metal plate 239 is installed on the inner wall of the bracket 237.

[0051] An inlet pipe 310 is detachably installed on the inlet throttling pipe 223. A flow sensor is installed at the outlet end of the inlet pipe 310. The flow sensor is electrically connected to the electromagnet 238. A controller is installed in the mounting cavity 120. Both the flow sensor and the electromagnet 238 are electrically connected to the controller. The flow sensor is used to monitor the temperature of the cooling medium at the outlet end of the inlet pipe 310 in real time. When the temperature of the cooling medium at the outlet end of the inlet pipe 310 is lower than a preset threshold, it sends an electrical signal to the controller. The controller receives the electrical signal and controls the electromagnet 238 to be energized.

[0052] It should be noted that the coordinated setup of the metal plate 239, electromagnet 238, and flow sensor achieves the linkage between adaptive flow regulation and electromagnetic positioning and locking. The flow sensor collects the temperature of the cooling medium at the outlet of the inlet pipe 310 after heat exchange in real time. When the temperature of the cooling medium at the outlet of the inlet pipe 310 is higher than the preset threshold, it sends an electrical signal to the controller. The controller receives the electrical signal and controls the electromagnet 238 to work. The electromagnet 238 generates a magnetic field that attracts the metal plate 239, locking the valve core 233 in the current position and keeping the flow gap constant. When the temperature of the cooling medium at the outlet of the inlet pipe 310 is lower than the preset threshold, the electromagnet 238 is de-energized, and the valve core 233 resumes its adaptive flow regulation function.

[0053] The housing 210 has an inlet chamber 213 on the side away from the buffer chamber 212. The top wall of the inlet chamber 213 has two inlet channels 214 that connect the buffer chamber 212 and the inlet chamber 213. The bottom wall of the equipment cavity 110 is connected to a supply pipe that communicates with the inlet chamber 213. The supply pipe is located between the two inlet channels 214.

[0054] It should be noted that by setting up the liquid inlet chamber 213 and the two liquid inlet channels 214, the flow rate and pressure of the medium in the liquid inlet chamber 213 can be effectively balanced, avoiding the problem of uneven local pressure and deviated flow of the cooling medium caused by the liquid supply pipe directly inputting the cooling medium into the buffer chamber 212.

[0055] A guide plate 215 is connected to the liquid inlet channel 214. The guide plate 215 has an arc-shaped arched grid structure, wherein the direction of the arc-shaped arch is directly opposite to the direction of the liquid inlet channel 214.

[0056] It should be noted that the guide plate 215 can be used to precisely rectify, stabilize, and reduce turbulence of the cooling medium entering the buffer chamber 212. After the cooling medium impacts the arc-shaped surface of the guide plate 215 at high speed, the flow velocity is uniformly released, and the radial turbulence and axial impact flow are sorted into a stable laminar flow, ensuring the balance and stability of the cooling medium pressure and flow velocity inside the buffer chamber 212. This provides a precise and stable pressure reference for the adaptive flow adjustment of the adjustment components 230 matched to each flow branch chamber 222.

[0057] Rubber pressure rings are provided on both sides of the elastic diaphragm 232, and a fixing ring for fixing the elastic diaphragm 232 is detachably installed on the bottom wall of the mounting port.

[0058] It should be noted that by setting the fixing ring and the rubber pressure ring, the edge of the elastic diaphragm 232 can be fully sealed and firmly limited. At the same time, it is convenient to disassemble and replace the elastic diaphragm 232. The rubber pressure ring can buffer the edge stress of the elastic diaphragm 232 during deformation, avoid edge cracking and fatigue damage caused by long-term reciprocating deformation of the elastic diaphragm 232, and extend the service life of the elastic diaphragm 232.

[0059] Specifically, during use, the cooling medium enters the inlet chamber 213 through the supply pipe and accumulates there. Then, it enters the buffer chamber 212 through the inlet channel 214. When passing through the inlet channel 214, the cooling medium flows into the inlet chamber 213 through the guide plate 215 to rectify and stabilize the pressure, ensuring that the hydraulic pressure in the buffer chamber 212 is stable and balanced. After the hydraulic pressure is stabilized and balanced, the cooling medium enters each branch chamber 222, enters the inlet pipe 310 through the inlet throttling pipe 223, and then enters the liquid cooling plate through the inlet pipe 310 to exchange heat with the heat-generating devices in the equipment. After heat exchange, it is collected in the collector 300 through the return pipe 320 and returned to the CDU heat exchange unit for circulation.

[0060] When the heating element in the device at the rear end of the liquid inlet throttling pipe 223 on the corresponding flow divider 222 is under high load and high heat consumption, the heat generated inside the device increases dramatically. The built-in liquid cooling plate exchanges heat fully with the heating element inside the device. After the cooling medium absorbs heat, the temperature of the cooling medium rises, the flow resistance increases, and the pressure inside the liquid inlet throttling pipe 223 rises accordingly. At this time, the pressure in the buffer chamber 212 on the front side of the elastic diaphragm 232 is less than the pre-tightening force of the first spring 236, which pushes the elastic diaphragm 232 to drive the valve core 233 to move axially in the direction of the liquid inlet throttling pipe 223. The flow gap between the valve core 233 and the liquid inlet throttling pipe 223 increases, which increases the cooling medium supply flow rate of the liquid inlet throttling pipe 223, compensating for the heat dissipation demand of the high-load device. The flow gap can be adaptively adjusted according to the power consumption of the heating element inside the device.

[0061] Meanwhile, the flow sensor monitors the temperature of the cooling medium at the outlet of the inlet pipe 310 in real time. When the temperature of the cooling medium at the outlet of the inlet pipe 310 is higher than the preset threshold, it sends an electrical signal to the controller. The controller receives the electrical signal and controls the electromagnet 238 to be energized, which attracts the metal plate 239 on the valve core 233 after the flow gap is adjusted, thereby locking the valve core 233 and preventing the flow gap from changing due to the movement of the valve core 233 caused by pressure changes in the flow channel. When the temperature of the cooling medium at the outlet of the inlet pipe 310 is lower than the preset threshold, the electromagnet 238 is de-energized, and the valve core 233 resumes its adaptive flow adjustment function.

[0062] Example 2

[0063] like Figures 9 to 13 As shown, this embodiment provides a liquid cooling pipeline installation assembly, including a mounting bracket 410. The mounting bracket 410 has an inverted L-shaped mounting surface, and multiple bending assemblies 420 and multiple guide members 430 for installing the liquid inlet pipe 310 are detachably mounted on the mounting surface.

[0064] The bending assembly 420 includes an L-shaped fastener 421 that fits against the mounting surface. The L-shaped fastener 421 has a horizontal part and a vertical part. There are semi-circular frames 423 on both sides of the horizontal part. A bending member for bending the liquid inlet pipe 310 with a large arc is rotatably installed between the semi-circular frames 423 on both sides of the horizontal part. A locking member 426 is installed on the bending member. The locking member 426 is used to cooperate with the semi-circular frames 423 to lock the bending member.

[0065] It should be noted that, through the cooperative arrangement of the horizontal and vertical parts of the L-shaped fastener 421, the semi-circular frame 423, and the bending component, the bending component can be pushed to rotate along the arc trajectory of the semi-circular frame 423 when the inlet pipe 310 is bent. This gradually bends the inlet pipe 310 to a state where it fits into the first and second mating grooves corresponding to the horizontal and vertical parts, achieving precise control of the bending radius of the inlet pipe 310. At the same time, the locking structure of the locking component 426 and the semi-circular frame 423 can achieve immediate locking after the pipe is bent, replacing the passive fixing method of traditional pipe clamps and cable ties. The bent state of the inlet pipe 310 can be maintained without additional tools, effectively preventing the pipe from collapsing or denting at the bend and ensuring the integrity of the flow section.

[0066] Furthermore, the liquid inlet pipe 310 can be formed by a single bend and lock, without the need for repeated calibration and adjustment, which improves the installation efficiency of liquid cooling pipes (i.e., liquid inlet pipe 310) in narrow spaces.

[0067] The bending component includes adjustable arms 424 rotatably mounted on both sides of the horizontal section. A clamping block 425 is rotatably mounted between the adjustable arms 424 on both sides of the horizontal section. The bottom wall of the clamping block 425 has an arc-shaped fitting part 4251. The fitting part 4251 extends along the length of the horizontal section. The arc-shaped fitting part 4251 matches the outer wall contour of the liquid inlet pipe 310, which can increase the contact area with the outer wall of the pipe and realize surface fitting pressure. This ensures that the pressure evenly covers the bent section of the pipe during the bending process and avoids pipe dents and collapses caused by excessive local pressure.

[0068] It should be noted that by setting the adjusting arm 424 and the clamping block 425, the clamping block 425 is rotatably installed between the adjusting arms 424 on both sides of the horizontal part, so that the clamping block 425 can rotate synchronously with the adjusting arm 424 during the bending process, and the arc-shaped fitting part 4251 of the clamping block 425 applies a uniform clamping force to the outer wall of the inlet pipe 310, thereby forming a continuous surface contact support for the inlet pipe 310 during the bending process, avoiding local stress concentration caused by point contact force, further reducing the risk of pipe collapse, and at the same time, it can accurately match the dynamic deformation process of pipe bending, and adapt to the bending operation of inlet pipes 310 with different diameters.

[0069] The side wall of the adjusting arm 424 is provided with a through groove 4241 for the semi-circular frame 423 to pass through. The width of the through groove 4241 is the same as the thickness of the semi-circular frame 423. The locking member 426 is provided on the outer wall of the adjusting arm 424, which makes it convenient for the user to directly operate the locking and unlocking from the outside.

[0070] It should be noted that by setting the width of the through groove 4241 to be the same as the thickness of the semi-circular frame 423, the axial offset or swaying of the adjusting arm 424 during rotation is restricted, ensuring that the bent part always moves along the preset arc trajectory, thereby ensuring the accuracy of the bending angle and bending radius of the liquid inlet pipe 310.

[0071] The outer wall of the semicircular frame 423 has a ratchet section 4231, and the outer wall of the adjusting arm 424 has a protrusion. The protrusion has a connecting cavity communicating with the through groove 4241. The locking member 426 includes a slider 4261 that is slidably disposed in the connecting cavity. One side wall of the slider 4261 has a locking block 4262 that cooperates with the ratchet section 4231. The other side wall of the slider 4261 has an extension rod that passes through the protrusion. A pull handle 4263 is connected to the end of the extension rod away from the slider 4261. A second spring 4264 is connected between the connecting cavity and the slider 4261. The second spring 4264 is used to provide elastic force to keep the slider 4261 pressed in the direction of the ratchet section 4231.

[0072] It should be noted that, through the coordinated arrangement of slider 4261, locking block 4262, extension rod, pull handle 4263, and second spring 4264, locking block 4262 remains engaged with ratchet section 4231 under the elastic force of second spring 4264. This allows the bent part to be locked step by step during rotation and to rotate only in one direction, achieving stepless adjustment and instant locking of the bending angle of inlet pipe 310. No additional bolts or buckles are required, simplifying the fixing process. When it is necessary to release the lock, simply pull handle 4263 outward to disengage locking block 4262 from ratchet section 4231. The operation is simple and quick, improving the efficiency of installation and maintenance of inlet pipe 310.

[0073] The top walls of the horizontal and vertical sections are respectively provided with a first mating groove and a second mating groove that mate with the outer wall of the liquid inlet pipe 310. An arc-shaped groove 422 connecting the first and second mating grooves is provided between the horizontal and vertical sections.

[0074] It should be noted that by opening the first mating groove and the second mating groove on the top wall of the horizontal and vertical parts respectively, and setting the arc groove 422 connecting the two between the horizontal and vertical parts, the liquid inlet pipe 310 can form a close fit and support with the vertical part, the arc groove 422 and the horizontal part respectively after bending. The arc groove 422 provides reserved space and guidance for the bending section of the liquid inlet pipe 310, so that it can be bent at a large arc along the arc groove 422, avoiding local compression or deformation of the liquid inlet pipe 310 in the bending transition area, and further ensuring the smooth flow of the liquid inlet pipe 310 after bending.

[0075] The rotation axis of the adjusting arm 424 is the same as the center of the arc groove 422.

[0076] It should be noted that by aligning the rotation axis of the adjusting arm 424 with the center of the arc groove 422, the force applied by the clamping block 425 to the inlet pipe 310 during the rotation of the bent part is always radially towards the center of the arc groove 422. This ensures that the inlet pipe 310 is subjected to uniform force during bending and that the bending path is consistent with the arc trajectory of the arc groove 422. This achieves precise control over the bending shape of the inlet pipe 310, reduces additional stress caused by bending path deviation, and further improves the bending effect.

[0077] A fixing ring 427 connected to the semi-circular frame 423 is installed between the two side walls of the vertical part. A through-hole for the liquid inlet pipe 310 to pass through is formed between the inner wall of the fixing ring 427 and the first mating groove. The fixing ring 427 is horizontally arranged and is used to support the adjusting arm 424. It can provide a limit stop when the bending part is rotated to the horizontal position to prevent the bending part from rotating excessively.

[0078] It should be noted that by setting a fixing ring 427 connected to the semi-circular frame 423, and forming a through-hole between the inner wall of the fixing ring 427 and the first mating groove for the liquid inlet pipe 310 to pass through, the liquid inlet pipe 310 can pass through the through-hole for circumferential limiting before bending, so as to avoid the liquid inlet pipe 310 deviating during bending and affecting the bending effect.

[0079] The top wall of the guide member 430 is provided with a through hole 431 for the liquid inlet pipe 310 to pass through.

[0080] It should be noted that by opening a through hole 431 on the top wall of the guide member 430, the liquid inlet pipe 310 can be precisely limited when passing through the guide member 430, thus guiding and constraining the direction of the liquid inlet pipe 310, ensuring that the liquid inlet pipe 310 maintains the preset straight direction before entering the bending assembly 420, and avoiding the positional deviation caused by the pipe's own weight or external force from affecting the bending accuracy.

[0081] Furthermore, the multiple guides 430 and multiple bending components 420 work together to meet the layout requirements of the liquid inlet pipes 310 of devices of different heights in narrow spaces such as server racks.

[0082] Specifically, in use, the user bolts the bending assembly 420 and guide 430 required for the corresponding height equipment onto the mounting bracket 410, then bolts multiple mounting brackets 410 into the mounting cavity 120 of the corresponding height equipment. Next, the liquid inlet pipe 310 is sequentially passed through the corresponding bending assembly 420 and guide 430, as shown in [the diagram / document / etc.]. Figure 2 and Figure 3 The state shown;

[0083] Taking any device of a corresponding height as an example, the user first rotates the bent part to the desired position. Figure 11 In the state shown, the bending piece is flush with the fixing ring 427. Then, the liquid inlet pipe 310 is passed through the through hole and the bending piece, and the liquid inlet pipe 310 is fitted with the second mating groove at the vertical part. The bending piece is rotated clockwise to fit the fitting part 4251 on the pressing block 425 with the outer wall of the liquid inlet pipe 310 until the outer wall of the liquid inlet pipe 310 is fitted with the first mating groove at the horizontal part. Due to the setting of the locking piece 426, the bent piece after rotation forms a one-way lock on the pressed and bent liquid inlet pipe 310, which can quickly be bent and fixed the liquid inlet pipe 310.

[0084] When it is necessary to release the bend in the inlet pipe 310, the user pulls the handle 4263 outward. The handle 4263 moves the extension rod outward, which in turn moves the slider 4261 outward. The slider 4261 then moves the locking block 4262 outward, disengaging it from the ratchet section 4231. The bent part can then be rotated to the contact position with the retaining ring 427. Figure 11 The state shown.
