Description

Technical Field

[0001] This utility model relates to a cabinet body, and more particularly to a liquid-cooled cabinet for liquid-cooled servers. Background Technology

[0002] With increasingly stringent national requirements for energy conservation in data centers, the high energy consumption of conventional air-cooled air conditioners leads to a high Power Usage Effectiveness (PUE), failing to meet national energy conservation standards. Therefore, a liquid-cooled energy-saving system is needed to replace the existing high-energy-consuming air-cooled air conditioners. In liquid-cooled energy saving, the coolant in the liquid-cooled server directly enters the server's interior to exchange heat with heat sources such as the CPU / GPU. Liquid-cooled servers (referred to as servers) are typically connected to a manifold via connectors and hoses. Therefore, there is a risk of leakage at the connector connections and solder joints. If leaked liquid cannot be drained in time, it will affect the normal operation and lifespan of the liquid-cooled server. Furthermore, besides the need for timely drainage of leaked liquid, there is also the risk of server burnout due to water spraying from leaks during operation or plugging / unplugging of the connectors. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to provide a liquid-cooled cabinet that can timely discharge leaked liquid through optimized structural design to ensure the normal operation and service life of the server. It can also effectively solve the problem of server burnout caused by water leakage during the operation or plugging and unplugging of the distribution connector, thus ensuring the reliability of the liquid-cooled cabinet.

[0004] To address this issue, the present invention provides a liquid-cooled server rack, comprising: a rack body, a water manifold, a first water receiving tray, and a first leak-proof device. The water manifold is disposed in the rack body and connected to each server in the rack body. The first water receiving tray is disposed at the bottom of the rack body and below the first leak-proof device. The first leak-proof device is disposed on the side of the water manifold and between the water manifold and the server.

[0005] A further improvement of this utility model is that the water distributor is provided with a first distribution connector, and the position of the first leak-proof device corresponds to the position of the first distribution connector.

[0006] A further improvement of this utility model is that the first leak-proof device includes a first baffle plate and a first guide plate, the first baffle plate being disposed on the side of the first leak-proof device and the first guide plate being disposed at the bottom of the first leak-proof device.

[0007] A further improvement of this utility model is that the first guide plate includes a side guide plate and a bottom guide plate connected to each other, and the side guide plate and the bottom guide plate are inclinedly arranged directly above the first water receiving tray.

[0008] A further improvement of this utility model is that the included angle between the side guide plate and the bottom guide plate is an obtuse angle.

[0009] A further improvement of this invention is that the first leak-proof device also includes mounting holes.

[0010] A further improvement of this utility model is that it also includes a second leak-proof device. The server is provided with a second distribution connector. The server is connected to the water distribution unit through the second distribution connector and the first distribution connector. The position of the second leak-proof device corresponds to the position of the second distribution connector.

[0011] A further improvement of this utility model is that the second anti-leakage device includes a second water receiving tray, a second water baffle, a third water baffle, a through-hole, and a drain pipe. The second water baffle is disposed on both sides of the second water receiving tray, the third water baffle is disposed on the back of the second water receiving tray near the server, the through-hole is disposed on the third water baffle, and the drain pipe is disposed at the bottom of the second water receiving tray.

[0012] A further improvement of this utility model is that the second anti-leakage device further includes a mounting bracket, and the second anti-leakage device is connected to the cabinet body through the mounting bracket.

[0013] A further improvement of this utility model is that it also includes a leakage detection component, which includes a leakage detector and a leakage detection rope. The leakage detection rope is disposed in the first water receiving tray, and the leakage detector is connected to the leakage detection rope.

[0014] Compared with existing technologies, the advantages of this invention are as follows: A first water collection tray is installed at the bottom of the liquid-cooled server rack, positioned below the first leak-proof device, enabling timely drainage of leaked liquid to ensure normal operation and service life of the server. Furthermore, the first leak-proof device is also installed on the side of the manifold, between the manifold and the server, effectively solving the problem of server burnout due to water leakage during operation or plugging / unplugging of the distribution connector, thus ensuring the reliability of the liquid-cooled server rack.

[0036] The preferred embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0037] like Figures 1 to 11 As shown, this embodiment provides a liquid-cooled server rack, including: a rack body 1, a water manifold 2, a first water receiving tray 3, and a first leak-proof device 4. The water manifold 2 is disposed in the rack body 1 and is connected to each server 5 in the rack body 1. The first water receiving tray 3 is disposed at the bottom of the rack body 1 and below the first leak-proof device 4. The first leak-proof device 4 is disposed on the side of the water manifold 2 and between the water manifold 2 and the server 5.

[0038] The manifold 2 described in this embodiment is used to realize the outlet and return of liquid. It may include a first distribution connector 201, a distributor 202, and a collector 203. Coolant is outleted to each server 5 through the distributor 202, the first distribution connector 201, a hose, and the second distribution connector 501. Then, the liquid after heat exchange is returned and collected through the second distribution connector 501, the hose, the first distribution connector 201, and the collector 203 to achieve liquid cooling circulation. The first drip tray 3 is located at the bottom of the cabinet body 1 and below the first leak-proof device 4, used to collect and drain leaked liquid. The first leak-proof device 4 is located on the side of the manifold 2 and between the manifold 2 and the server 5, effectively solving the problem of server 5 burning out due to water leakage during operation or plugging / unplugging of the distributor connector of the manifold 2. The server 5 refers to a liquid-cooled server.

[0039] Therefore, this embodiment not only promptly drains leaked liquid to ensure the normal operation and lifespan of server 5, but also effectively solves the problem of server 5 burning out due to water leakage during the operation or plugging / unplugging of the distribution connector, ensuring the reliability of the liquid-cooled cabinet. The overall structure of this embodiment is reasonable and efficient, with high safety and reliability, and is easy to assemble and maintain.

[0040] like Figure 1 and Figure 2 As shown, the water manifold 2 in this embodiment is provided with a first distribution connector 201, and the position of the first leak-proof device 4 corresponds to the position of the first distribution connector 201. In this embodiment, the first leak-proof device 4 is used to block the first distribution connector 201 of the water manifold 2, preventing liquid from spraying onto the server 5 when the distribution connector leaks, thereby effectively avoiding the risk of damage to the server 5.

[0041] More specifically, such as Figures 3 to 8As shown, in this embodiment, the first leak-proof device 4 includes a first baffle plate 401 and a first guide plate. The first baffle plate 401 is disposed on the side of the first leak-proof device 4. This side can be single-sided or double-sided, depending on the actual application scenario and installation requirements. The first guide plate is disposed at the bottom of the first leak-proof device 4. The first guide plate is used to guide the leaked liquid to the first water receiving tray 3 at the bottom of the cabinet body 1, so that it can be discharged outdoors through the first water receiving tray 3. Optionally, the first guide plate includes a side guide plate 402 and a bottom guide plate 403 connected to each other. The side guide plate 402 and the bottom guide plate 403 are obliquely disposed directly above the first water receiving tray 3. If the first distribution joint 201 leaks, the leaking liquid (i.e., coolant) is blocked by the first leak-proof device 4 and its first baffle 401, flows downward along the first leak-proof device 4, and is guided by the side guide plate 402 and the bottom guide plate 403 to the first water receiving tray 3 at the bottom. Figure 1 and Figure 2 As shown, the water is then discharged outdoors through the first water receiving tray 3.

[0042] like Figures 6 to 8 As shown, in this embodiment, the guiding angles of the side guide plate 402 and the bottom guide plate 403 are both acute angles. Optionally, the guiding angle 'a' of the side guide plate 402 is smaller than the guiding angle 'b' of the bottom guide plate 403 to meet the actual requirements of guiding area and guiding flow rate. For example, the guiding angle 'a' between the side guide plate 402 and the vertical edge can be 20°, and the guiding angle 'b' between the bottom guide plate 403 and the vertical edge can be 42°. Of course, the guiding angles 'a' and 'b' can also be selected and adjusted according to actual needs. Optionally, in this embodiment, the included angle 'c' between the side guide plate 402 and the bottom guide plate 403 is an obtuse angle, such as an obtuse angle between 100° and 120°. Of course, the obtuse angle 'c' can also be selected and adjusted according to actual needs.

[0043] like Figure 3 and Figure 4 As shown, in this embodiment, the first leak-proof device 4 also includes mounting holes 404. The mounting holes 404 include a plurality of mounting holes provided on the side to realize the installation and fixation of the first leak-proof device 4, and the mounting holes 404 in different positions can be selected according to different liquid cooling cabinets to improve its adaptability.

[0044] like Figure 1 , Figure 2 as well as Figures 9 to 11As shown, this embodiment also includes a second leak-proof device 6. The server 5 is provided with a second distribution connector 501. The server 5 is connected to the water distribution manifold 2 through the second distribution connector 501 and the first distribution connector 201. The position of the second leak-proof device 6 corresponds to the position of the second distribution connector 501.

[0045] In this embodiment, the server 5 is used to connect to the manifold 2. The second distribution connector 501 is installed inside the second anti-leakage device 6. Since the second distribution connector 501 also has the potential for leakage, such as leakage due to the quality of the liquid or plugging and unplugging, the corresponding leakage will not spray onto the server 5 through the setting of the second anti-leakage device 6. Therefore, the risk of damaging the server 5 can be effectively avoided. The leakage can flow along the drain pipe 605 of the second anti-leakage device 6 to the first water receiving tray 3 at the bottom.

[0046] More specifically, such as Figures 9 to 11 As shown, the second leak-proof device 6 in this embodiment includes a second water receiving tray 601, a second water baffle 602, a third water baffle 603, a through-hole 604, and a drain pipe 605. The second water baffle 602 is disposed on both sides of the second water receiving tray 601, the third water baffle 603 is disposed on the back of the second water receiving tray 601 near the server 5, the through-hole 604 is disposed on the third water baffle 603, and the drain pipe 605 is disposed at the bottom of the second water receiving tray 601. When the second distribution connector 501 leaks, the leaking liquid will be blocked by the second water baffle 602 and the third water baffle 603 and flow to the second water receiving tray 601. The second water receiving tray 601 drains the liquid to the first water receiving tray 3 through the drain pipe 605 at its bottom, so that it can finally be discharged outdoors.

[0047] In practical applications, since the sizes of servers 5 vary from manufacturer to manufacturer, and since the second anti-leakage device 6 needs to be installed and set up close to the server 5, the actual installation position of the second anti-leakage device 6 is not fixed and needs to be adjusted on-site, which in turn affects the assembly efficiency of the product.

[0048] Therefore, such as Figure 10 and Figure 11As shown, optionally, in this embodiment, the second leak-proof device 6 further includes a mounting bracket 606, through which the second leak-proof device 6 is connected to the cabinet body 1. More specifically, the mounting bracket 606 includes a top bent fixing end and a bottom bent fixing end. Therefore, the second leak-proof device 6 can be fixed to the bottom and top side panels of the cabinet body 1 via the mounting bracket 606. The side panels of the cabinet body 1 have a row of fixing holes, allowing for adaptive adjustments to the installation position according to the actual server 5, facilitating product assembly and maintenance, improving efficiency, and meeting the requirement of close contact with the server 5 during assembly.

[0049] like Figure 1 and Figure 2 As shown, optionally, this embodiment also includes a leak detection component 7, which includes a leak detector and a leak detection rope. The leak detection rope is disposed in the first water receiving tray 3, and the leak detector is connected to the leak detection rope.

[0050] Optionally, in this embodiment, one end of the leak detector is connected to the monitoring host, and the other end is connected to the leak detection rope, which is wrapped around the inner bottom of the first water receiving tray 3. When leaked liquid flows to the first water receiving tray 3, the liquid comes into contact with the leak detection rope, causing the rope to become conductive. The leak detector transmits this conductivity information to the monitoring host. Upon receiving the conductivity information, the monitoring host triggers a leak alarm, providing a better basis for notifying management personnel to handle the situation promptly.

[0051] The specific embodiments described above are preferred embodiments of this utility model, and are not intended to limit the specific scope of this utility model. The scope of this utility model includes, but is not limited to, these specific embodiments. All equivalent changes made in accordance with the shape and structure of this utility model are within the protection scope of this utility model.
