Description

Technical Field

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

[0002] A server is a type of computer that runs faster, handles higher loads, and is more expensive than a regular computer. Servers provide computing or application services to other client machines on a network. Servers possess high-speed computing power, long-term reliable operation, powerful input / output external data throughput capabilities, and better scalability. Generally, servers are capable of responding to service requests, providing services, and ensuring service availability, depending on the services they provide. In data centers, to improve data processing capabilities, numerous server racks are used for server installation and fixation. However, servers generate a lot of heat during operation. To maintain normal operating temperatures, liquid cooling systems are typically used to cool the entire server rack. Since some servers may be idle or shut down during actual use, this can easily lead to energy waste. Summary of the Invention

[0003] In view of this, the present invention provides a liquid-cooled server device to solve the problem that in order to keep the server at a normal operating temperature, a liquid cooling system is usually set up to cool down the entire server cabinet. However, during the actual use of the server cabinet, some servers will be in standby or shut down, which can easily cause energy loss.

[0004] This invention provides a liquid-cooled server device, including a server cabinet, multiple server unit structures, multiple unit connection mechanisms, and a liquid cooling mechanism. The multiple server unit structures are sequentially arranged within the server cabinet, each server unit structure including adjacent server modules and heat exchange structures, with each server module having an internal temperature sensing device. The multiple unit connection mechanisms are arranged within the server cabinet, corresponding to the multiple server unit structures. The liquid cooling mechanism is arranged within the server cabinet and connected to the multiple heat exchange structures through the multiple unit connection mechanisms. The liquid cooling mechanism includes an intelligent cold source module, which is signal-connected to the multiple temperature sensing devices and the multiple unit connection mechanisms, for receiving temperature data output by the temperature sensing devices and controlling the connection or disconnection of the corresponding unit connection mechanisms based on the temperature data.

[0005] Beneficial effects: The intelligent cooling source module is signal-connected to multiple temperature sensing devices and multiple unit connection mechanisms. It receives temperature data output by the temperature sensing devices and controls the connection or disconnection of the corresponding unit connection mechanism according to the temperature data. This improves the intelligent cooling source module's overall control capability over the server rack. When the temperature of a server unit is low or it is not in use, the unit connection mechanism corresponding to that server unit will be disconnected, reducing cooling source loss, effectively improving energy utilization efficiency, reducing energy consumption, and improving the cooling effect of the liquid cooling mechanism on the server rack as a whole.

[0006] In one optional embodiment, the liquid cooling mechanism includes an internal water supply pipeline and an internal water return pipeline, both of which are connected to the intelligent cold source module. The unit connection mechanism includes a first connecting branch pipe, a second connecting branch pipe, a first solenoid valve, and a second solenoid valve. One end of the first connecting branch pipe is connected to the internal water supply pipeline, and the other end is connected to the inlet pipe of the heat exchange structure. One end of the second connecting branch pipe is connected to the internal water return pipeline, and the other end is connected to the outlet pipe of the heat exchange structure. The first solenoid valve is mounted on the first connecting branch pipe and is signal-connected to the intelligent cold source module. The second solenoid valve is mounted on the second connecting branch pipe and is signal-connected to the intelligent cold source module.

[0007] Beneficial effects: By setting up internal water supply pipes, internal water return pipes, a first connecting branch pipe, and a second connecting branch pipe, the intelligent cold source module can be connected to multiple heat exchange structures. By setting a first solenoid valve on the first connecting branch pipe and a second solenoid valve on the second connecting branch pipe, and since both the first and second solenoid valves are signal-connected to the intelligent cold source module, the intelligent cold source module can control the opening or closing of the first and second solenoid valves according to the temperature data output by the temperature sensing device, thereby controlling the connection or disconnection of the first and second connecting branch pipes, and achieving precise control of the unit connection mechanism.

[0008] In one optional embodiment, the unit connection mechanism further includes a first fixed pipe head, a first movable pipe head, a first sealing gasket, a second fixed pipe head, a second movable pipe head, a second sealing gasket, a positioning frame, a positioning cylinder, and a sliding insert rod; the first fixed pipe head is fixedly connected to one end of the first connecting branch pipe that communicates with the water inlet pipe; the first movable pipe head is fixedly connected to one end of the water inlet pipe that communicates with the first connecting branch pipe, and is detachably connected to the first fixed pipe head; the first sealing gasket is disposed between the first fixed pipe head and the first movable pipe head; the second fixed pipe head is fixedly connected to the second connecting branch pipe that communicates with the water outlet pipe. One end of the positioning frame; the second movable pipe head is fixedly connected to the end of the outlet pipe that communicates with the second connecting branch pipe, and is detachably connected to the second fixed pipe head; the second sealing gasket is disposed between the second fixed pipe head and the second movable pipe head; positioning holes are respectively provided at both ends of the positioning frame; the first connecting branch pipe passes through one of the positioning holes and is connected to the first fixed pipe head; the second connecting branch pipe passes through the other positioning hole and is connected to the second fixed pipe head; the positioning cylinder is disposed on the side of the positioning frame near the server unit mechanism; the sliding insertion rod is disposed on the server unit mechanism and is slidably inserted into the positioning cylinder.

[0009] Beneficial effects: By setting a first fixed pipe head and a first movable pipe head, a detachable connection can be achieved between the first connecting branch pipe and the inlet pipe; by setting a second fixed pipe head and a second movable pipe head, a detachable connection can be achieved between the second connecting branch pipe and the outlet pipe. By setting a first sealing gasket to seal the gap between the first fixed pipe head and the first movable pipe head, liquid leakage is prevented from this gap. Similarly, by setting a second sealing gasket to seal the gap between the second fixed pipe head and the second movable pipe head, liquid leakage is prevented from this gap, reducing the possibility of server moisture absorption and improving the stability of the liquid cooling system. The sliding connection between the positioning frame and the server unit mechanism is achieved through the positioning cylinder and the sliding rod, which limits the position of the positioning frame and the server unit mechanism, thereby ensuring that the central axes of the first fixed pipe head and the first movable pipe head are aligned, improving the stability of their docking; and also ensuring that the central axes of the second fixed pipe head and the second movable pipe head are aligned, further improving the stability of their docking.

[0010] In one optional embodiment, the unit communication mechanism further includes a sealing cover, with the positioning frame located inside the sealing cover. The sealing cover includes two first connecting holes, two second connecting holes, a through hole, and two limiting holes. The two first connecting holes are respectively located at both ends of the sealing cover. A first connecting branch pipe passes through one of the first connecting holes and connects to the first fixed pipe head. A second connecting branch pipe passes through the other first connecting hole and connects to the second fixed pipe head. The two second connecting holes are both located on the side of the sealing cover near the server unit mechanism, and are slidably connected to the first movable pipe head and the second movable pipe head, respectively. The through hole is located on the side of the sealing cover near the server unit mechanism. One end of the positioning cylinder is fixedly connected to the positioning frame, and the other end passes through the through hole. Two limiting blocks protrude from the side of the positioning frame away from the server unit mechanism. The two limiting blocks are respectively located in the two limiting holes and are fixedly connected to the two limiting holes.

[0011] Beneficial effects: By using a sealing cover to shield the unit communication mechanism, liquid inside the first fixed pipe head and the first movable pipe head, or the second fixed pipe head and the second movable pipe head, is prevented from flowing into the server cabinet during disassembly of the server unit mechanism, thus preventing equipment damage and improving the safety of server module operation inside the server cabinet. The first and second connecting holes allow the connection points of the first fixed pipe head and the first movable pipe head, as well as the connection points of the second fixed pipe head and the second movable pipe head, to be located inside the sealing cover. Furthermore, since the two second connecting holes are slidably connected to the first and second movable pipe heads respectively, the installation and disassembly of the server unit mechanism are facilitated. The through hole facilitates the sliding insertion between the positioning cylinder and the sliding rod; the limiting hole facilitates the fixed connection between the positioning frame and the sealing cover.

[0012] In one optional embodiment, the liquid cooling mechanism further includes multiple connecting pipes and a water tank; two adjacent sealing covers of the multiple connecting pipes are connected through the connecting pipes; the water tank is located at the bottom of the server cabinet and is connected to the intelligent cold source module, and the water tank is connected to the sealing cover located at the bottom through the connecting pipes.

[0013] Beneficial effects: By setting up connecting pipes and a water storage tank, the liquid collected by the sealing cover can be introduced into the interior of the water storage tank. Since the water storage tank is connected to the intelligent cold source module, when there is a lot of liquid stored in the water storage tank, the liquid inside the water storage tank can enter the interior of the intelligent cold source module for liquid cooling and recycling again.

[0014] In one optional embodiment, the server cabinet includes a support frame; the liquid-cooled server device further includes multiple sliding mechanisms, and the multiple server unit mechanisms are respectively slidably connected to the server cabinet along a first direction through the multiple sliding mechanisms; the sliding mechanism includes a support slide plate and two sets of positioning slide rails; the support slide plate is connected to the server unit mechanism, and both ends protrude from the server unit mechanism; the two sets of positioning slide rails are arranged opposite to each other on both sides of the support frame, and both ends of the support slide plate are respectively slidably connected to the two sets of positioning slide rails along the first direction; the first direction is the length direction of the server cabinet.

[0015] Beneficial effects: Since the server cabinet includes a support frame, by setting up support slides and positioning slides, the server unit mechanism can be slidably connected to the server cabinet in the first direction, which facilitates the installation and disassembly of the server unit mechanism in the first direction; and by setting up positioning slides, the server unit mechanism can be fixed and its operating range can be limited.

[0016] In one optional embodiment, a plurality of fixing mechanisms are further included, each of which is respectively configured corresponding to a plurality of server unit mechanisms; the fixing mechanisms are disposed on one side of the server unit mechanism in a second direction; each fixing mechanism includes a stop and a sliding structure; the stop is located between the support frame and the server unit mechanism, disposed on the side of the support frame away from the liquid cooling mechanism, and fixedly connected to the support frame; the sliding structure is slidably connected to the server unit mechanism along the second direction and is used to engage with the stop; the second direction is the width direction of the server cabinet.

[0017] Beneficial effects: By setting up a fixing mechanism, the position of the server unit can be fixed, preventing changes in the relative position of the server unit with the server cabinet during operation and improving the stability of equipment operation; by using the sliding structure and the locking of the stop, the server unit is prevented from sliding along the first direction after installation, thus achieving fixation of the server unit; by using the sliding structure to slidably connect with the server unit along the second direction, the sliding structure can be disengaged from the stop during the installation or disassembly of the server unit, facilitating the replacement and maintenance of the server unit.

[0018] In one optional embodiment, the sliding structure includes an electric push rod and a sliding assembly; the fixed end of the electric push rod is fixedly connected to the server unit mechanism; one end of the sliding assembly is fixedly connected to the drive end of the electric push rod, and the other end is used to engage with the stop block.

[0019] Beneficial effects: By setting up electric push rods and sliding components, it is possible to achieve both a fixed connection between the sliding structure and the server unit mechanism, and a locking mechanism between the sliding structure and the stop block; in addition, the electric push rods can also achieve automatic control of the sliding components when they slide in the second direction, which facilitates the installation and disassembly of the server unit mechanism.

[0020] In one optional embodiment, the sliding assembly includes a sliding chamber, a sliding block, and an elastic element; the sliding chamber is fixedly connected to the drive end of the electric push rod; one end of the sliding block is disposed inside the sliding chamber, and the other end protrudes from the sliding chamber and is used to engage with the stop block; the elastic element is located inside the sliding chamber, and its two ends are fixedly connected to the sliding chamber and the sliding block, respectively.

[0021] Beneficial effects: By setting up an elastic element to achieve a sliding connection between the sliding block and the sliding chamber, during the installation or disassembly of the server unit mechanism, the sliding block and the stop block abut against each other under pressure. Under the elastic force of the elastic element, the sliding block moves towards the side closer to the sliding chamber, avoiding interference between the sliding block and the stop block, and facilitating the installation and disassembly of the server unit mechanism; and when the sliding block and the stop block are locked together, the setting of the elastic element can also provide a buffer for the sliding block, making the locking between the sliding block and the stop block tighter.

[0022] In one optional embodiment, the server cabinet further includes at least one sealing side plate, and the sealing side plate is detachably connected to the support frame; the unit communication mechanism is disposed on one side of the server cabinet in the first direction, and the sealing side plate is disposed on the side where the unit communication mechanism is located.

[0023] Beneficial effects: By setting the unit connection mechanism on one side of the server cabinet in the first direction, the server unit mechanism can slide relative to the server cabinet in the first direction during the installation and disassembly of the server unit mechanism; since the sealed side plate is detachably connected to the support frame, it is convenient to maintain and replace the server unit mechanism inside the server cabinet, thereby improving the stability and safety of the server unit mechanism.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] The following is combined with Figures 1 to 7 The following describes embodiments of the present invention.

[0036] According to an embodiment of the present invention, a liquid-cooled server device is provided, including a server cabinet 1, multiple server unit mechanisms 2, multiple unit connection mechanisms 3, and a liquid cooling mechanism 4. The multiple server unit mechanisms 2 are sequentially arranged within the server cabinet 1. Each server unit mechanism 2 includes adjacently arranged server modules 201 and heat exchange structures 202, and each server module 201 has a temperature sensing device inside. The multiple unit connection mechanisms 3 are arranged within the server cabinet 1, corresponding to the multiple server unit mechanisms 2 respectively. The liquid cooling mechanism 4 is arranged within the server cabinet 1, and is connected to the multiple heat exchange structures 202 respectively through the multiple unit connection mechanisms 3. The liquid cooling mechanism 4 includes an intelligent cold source module 401, which is signal-connected to the multiple temperature sensing devices and to the multiple unit connection mechanisms 3, for receiving temperature data output by the temperature sensing devices and controlling the connection or disconnection of the corresponding unit connection mechanism 3 according to the temperature data.

[0037] The intelligent cooling source module 401 is signal-connected to multiple temperature sensing devices and multiple unit connection mechanisms 3. It is used to receive temperature data output by the temperature sensing devices and control the connection or disconnection of the corresponding unit connection mechanism 3 according to the temperature data. This improves the overall control capability of the intelligent cooling source module 401 over the server rack. When the temperature of the server unit mechanism 2 is low or it is not in use, the unit connection mechanism 3 corresponding to the server unit mechanism 2 will be disconnected to reduce the loss of the cooling source, effectively improve energy utilization efficiency, reduce energy consumption, and improve the cooling effect of the liquid cooling mechanism 4 on the overall server rack.

[0038] In a specific implementation, the server unit structure 2 also includes a fixed chassis 203, in which the server module 201 and the heat exchange structure 202 are both disposed.

[0039] Specifically, thermal grease is filled between the server module 201 and the heat exchange structure 202. The thermal grease increases the contact area between the heat exchange structure 202 and the server module 201, which helps to accelerate the heat transfer efficiency between the server module 201 and the heat exchange structure 202, thereby improving the heat dissipation efficiency of the server module 201.

[0040] In a specific implementation, the server unit mechanism 2 also includes a server panel 204, a temperature sensing device inside the server module 201 is connected to the server panel 204, and the server panel 204 is connected to the intelligent cold source module 401.

[0041] In one embodiment, the liquid cooling mechanism 4 includes an internal water supply pipe 402 and an internal water return pipe 403, both of which are connected to the intelligent cold source module 401. The unit connection mechanism 3 includes a first connecting branch pipe 301, a second connecting branch pipe 302, a first solenoid valve 303, and a second solenoid valve 304. One end of the first connecting branch pipe 301 is connected to the internal water supply pipe 402, and the other end is connected to the inlet pipe 2021 of the heat exchange structure 202. One end of the second connecting branch pipe 302 is connected to the internal water return pipe 403, and the other end is connected to the outlet pipe 2022 of the heat exchange structure 202. The first solenoid valve 303 is mounted on the first connecting branch pipe 301 and is signal-connected to the intelligent cold source module 401. The second solenoid valve 304 is mounted on the second connecting branch pipe 302 and is signal-connected to the intelligent cold source module 401.

[0042] By setting up an internal water supply pipe 402, an internal water return pipe 403, a first connecting branch pipe 301, and a second connecting branch pipe 302, the intelligent cold source module 401 can be connected to multiple heat exchange structures 202. By setting a first solenoid valve 303 on the first connecting branch pipe 301 and a second solenoid valve 304 on the second connecting branch pipe 302, and since both the first solenoid valve 303 and the second solenoid valve 304 are signal-connected to the intelligent cold source module 401, the intelligent cold source module 401 can control the opening or closing of the first solenoid valve 303 and the second solenoid valve 304 according to the temperature data output by the temperature sensing device, thereby controlling the connection or disconnection of the first connecting branch pipe 301 and the second connecting branch pipe 302, and achieving precise control of the unit connection mechanism 3.

[0043] Specifically, the fixed chassis 203 has two first through holes on the side near the liquid cooling mechanism 4. The water inlet pipe 2021 of the heat exchange structure 202 passes through one of the first through holes and is connected to the first connecting branch pipe 301, and the water outlet pipe 2022 passes through the other first through hole and is connected to the second connecting branch pipe 302.

[0044] In a specific implementation, the intelligent cooling source module 401 is installed at the bottom of the server cabinet 1. The liquid cooling mechanism 4 also includes an external water supply pipe 406 and an external water return pipe 407. Both the external water supply pipe 406 and the external water return pipe 407 are located below the server cabinet 1. The bottom plate of the server cabinet 1 is provided with two second through holes. One end of the third connecting branch pipe is connected to the external water supply pipe 406, and the other end passes through one of the second through holes and is connected to the intelligent cooling source module 401. One end of the fourth connecting branch pipe is connected to the external water return pipe 407, and the other end passes through another second through hole and is connected to the intelligent cooling source module 401. The external water supply pipeline 406 delivers low-temperature cooling water from the outside to the intelligent cold source module 401. The intelligent cold source module 401 then delivers the cold water to the internal water supply pipeline 402. The inlet pipe 2021 delivers the cooling water from the internal water supply pipeline 402 to the heat exchange structure 202 to cool the heat exchange structure 202. The outlet pipe 2022 delivers the high-temperature water from the heat exchange structure 202 to the internal return water pipeline 403. The intelligent cold source module 401 then delivers the high-temperature water from the internal return water pipeline 403 to the external return water pipeline 407. The external return water pipeline 407 delivers the high-temperature water to the outside for cooling.

[0045] In a specific implementation, the heat exchange structure 202 is a finned condenser.

[0046] In a specific implementation, the intelligent cold source module 401 includes a water storage structure, which includes a cold water tank and a hot water tank. Both the external water supply pipe 406 and the internal water supply pipe 402 are connected to the cold water tank, and a water pump is installed inside the cold water tank to pump the cold water supplied by the external water supply pipe 406 into the internal water supply pipe 402. Both the external return water pipe 407 and the internal return water pipe 403 are connected to the hot water tank. The high-temperature water from the internal return water pipe 403 flows into the hot water tank and is then directly fed into the external return water pipe 407, and then... 407 delivers high-temperature water to the outside; the cold water tank can store excess cold and high-temperature water, ensuring a timely and sufficient supply of cold water to the internal water supply pipe 402; the hot water tank can store and collect the high-temperature water flowing out of the internal return water pipe 403, preventing the situation where too much high-temperature water flowing out of the internal return water pipe 403 cannot flow out of the external return water pipe 407 in time, thus ensuring the safety of the liquid cooling mechanism 4 during use; and the setting of the cold water tank and the hot water tank can separate the cold water and the high-temperature water, ensuring the cooling effect of the cold water.

[0047] In one embodiment, the unit communication mechanism 3 further includes a first fixed pipe head 305, a first movable pipe head 306, a first sealing gasket 307, a second fixed pipe head 308, a second movable pipe head 309, a second sealing gasket 310, a positioning frame 311, a positioning cylinder 312, and a sliding insert rod 313; the first fixed pipe head 305 is fixedly connected to one end of the first connecting branch pipe 301 that communicates with the water inlet pipe 2021; the first movable pipe head 306 is fixedly connected to one end of the water inlet pipe 2021 that communicates with the first connecting branch pipe 301, and is detachably connected to the first fixed pipe head 305; the first sealing gasket 307 is disposed between the first fixed pipe head 305 and the first movable pipe head 306; the second fixed pipe head 308 is fixedly connected to the second connecting branch pipe 302 that communicates with the water outlet pipe 2022. One end of the pipe is open; the second movable pipe head 309 is fixedly connected to the end of the water outlet pipe 2022 that communicates with the second connecting branch pipe 302, and is detachably connected to the second fixed pipe head 308; the second sealing gasket 310 is disposed between the second fixed pipe head 308 and the second movable pipe head 309; the positioning frame 311 has positioning holes 3111 at both ends; the first connecting branch pipe 301 passes through one of the positioning holes 3111 and is connected to the first fixed pipe head 305; the second connecting branch pipe 302 passes through the other positioning hole 3111 and is connected to the second fixed pipe head 308; the positioning cylinder 312 is disposed on the side of the positioning frame 311 near the server unit mechanism 2; the sliding insertion rod 313 is disposed on the server unit mechanism 2 and is slidably inserted into the positioning cylinder 312.

By setting the first sealing gasket 307 to seal the gap between the first fixed pipe head 305 and the first movable pipe head 306, liquid leakage is prevented from the gap between the first fixed pipe head 305 and the first movable pipe head 306. By setting the second sealing gasket 310 to seal the gap between the second fixed pipe head 308 and the second movable pipe head 309, liquid leakage is prevented from the gap between the second fixed pipe head 308 and the second movable pipe head 309, reducing the possibility of server moisture and improving the stability of the liquid cooling system operation. The positioning cylinder 312 and the sliding rod 313 achieve a sliding connection between the positioning frame 311 and the server unit mechanism 2, which can limit the position of the positioning frame 311 and the server unit mechanism 2, so that the central axes of the first fixed tube head 305 and the first movable tube head 306 are on the same straight line, thereby improving the stability of the docking of the first fixed tube head 305 and the first movable tube head 306; and make the central axes of the second fixed tube head 308 and the second movable tube head 309 on the same straight line, thereby improving the stability of the docking of the second fixed tube head 308 and the second movable tube head 309.

[0049] Specifically, the sliding rod 313 is fixed to the side of the fixed chassis 203 near the liquid cooling mechanism 4.

[0050] In a specific embodiment, the first fixed tube head 305 is provided with a first protruding end, and the first movable tube head 306 is inserted and connected to the first protruding end. Specifically, the first sealing gasket 307 is sleeved on the outer periphery of the first protruding end. The second fixed tube head 308 is provided with a second protruding end, and the second movable tube head 309 is inserted and connected to the second protruding end. Specifically, the second sealing gasket 310 is sleeved on the outer periphery of the second protruding end.

[0051] In one embodiment, the unit communication mechanism 3 further includes a sealing cover 314, the positioning frame 311 is located inside the sealing cover 314, and the sealing cover 314 includes two first connecting holes 3141, two second connecting holes 3142, a through hole 3143, and two limiting holes 3144; the two first connecting holes 3141 are respectively disposed at both ends of the sealing cover 314, the first connecting branch pipe 301 passes through one of the first connecting holes 3141 and is connected to the first fixing pipe head 305; the second connecting branch pipe 302 passes through the other first connecting hole 3141 and is connected to the second fixing pipe head 308; both second connecting holes 3142 are located inside the sealing cover 314.

The two limiting blocks 3112 are located in the two limiting holes 3144, respectively, and are fixedly connected to the two limiting holes 3144.

[0052] By providing a sealing cover 314 to shield the unit communication mechanism 3, liquid inside the first fixed pipe head 305 and the first movable pipe head 306 or the second fixed pipe head 308 and the second movable pipe head 309 is prevented from flowing into the server cabinet 1 and causing equipment damage when the server unit mechanism 2 is disassembled, thus improving the safety of the server module 201 operating inside the server cabinet 1. The first connecting hole 3141 and the second connecting hole 3142 allow the connection points of the first fixed pipe head 305 and the first movable pipe head 306, as well as the connection points of the second fixed pipe head 308 and the second movable pipe head 309, to be located inside the sealing cover 314. Since the two second connecting holes 3142 are slidably connected to the first movable pipe head 306 and the second movable pipe head 309 respectively, the installation and disassembly of the server unit mechanism 2 are facilitated. The through hole 3143 facilitates the sliding insertion between the positioning cylinder 312 and the sliding rod 313; the limiting hole 3144 allows for a fixed connection between the positioning frame 311 and the sealing cover 314.

[0053] In one embodiment, the liquid cooling mechanism 4 further includes multiple connecting pipes 404 and a water tank 405; two adjacent sealing covers 314 of the multiple connecting pipes 404 are connected through the connecting pipes 404; the water tank 405 is located at the bottom of the server cabinet 1 and is connected to the intelligent cold source module 401, and the water tank 405 is connected to the sealing cover 314 located at the bottom through the connecting pipes 404.

[0054] By setting up a connecting pipe 404 and a water storage tank 405, the liquid collected by the sealing cover 314 can be introduced into the interior of the water storage tank 405. Since the water storage tank 405 is connected to the intelligent cold source module 401, when there is a lot of liquid stored inside the water storage tank 405, the liquid inside the water storage tank 405 can enter the interior of the intelligent cold source module 401 for liquid cooling recycling again.

[0055] In a specific implementation, a water pump is installed inside the water storage tank 405. When the water storage tank 405 contains a large amount of liquid, the water pump inside the water storage tank 405 is used to transport the liquid inside the water storage tank 405 to the intelligent cold source module 401, thereby realizing the recycling of the cooling liquid.

[0056] In one embodiment, the server cabinet 1 includes a support frame 101; the liquid-cooled server device further includes multiple sliding mechanisms 5, and multiple server unit mechanisms 2 are respectively slidably connected to the server cabinet 1 along a first direction through the multiple sliding mechanisms 5; the sliding mechanism 5 includes a support slide plate 501 and two sets of positioning slide rails 502; the support slide plate 501 is connected to the server unit mechanism 2, and both ends protrude from the server unit mechanism 2; the two sets of positioning slide rails 502 are arranged opposite to each other on both sides of the support frame 101, and both ends of the support slide plate 501 are respectively slidably connected to the two sets of positioning slide rails 502 along the first direction; the first direction is the length direction of the server cabinet 1.

[0057] Since the server cabinet 1 includes a support frame 101, by setting a support slide plate 501 and a positioning slide rail 502, the server unit mechanism 2 can be slidably connected to the server cabinet 1 in the first direction, which facilitates the installation and disassembly of the server unit mechanism 2 in the first direction; and by setting the positioning slide rail 502, the server unit mechanism 2 can be fixed and the operating range of the server unit mechanism 2 can be limited.

[0058] Specifically, the support slide 501 is fixedly connected to the fixed chassis 203.

[0059] In a specific implementation, a support crossbar is provided on the support frame 101, and the positioning slide rail 502 is provided on the support crossbar. The support crossbar supports and fixes the positioning slide rail 502. In addition, the support crossbar can also reinforce the support frame 101, prevent the server unit mechanism 2 from swinging, improve the stability of the server module 201 operation, and make the unit connection mechanism 3 more stably connect the server unit mechanism 2 and the liquid cooling mechanism 4 together.

[0060] In one embodiment, a plurality of fixing mechanisms 6 are further included, each of which is respectively configured corresponding to a plurality of server unit mechanisms 2; the fixing mechanism 6 is disposed on one side of the server unit mechanism 2 in a second direction; the fixing mechanism 6 includes a stop 601 and a sliding structure; the stop 601 is located between the support frame 101 and the server unit mechanism 2, disposed on the side of the support frame 101 away from the liquid cooling mechanism 4, and is fixedly connected to the support frame 101; the sliding structure is slidably connected to the server unit mechanism 2 along the second direction and is used to engage with the stop 601; the second direction is the width direction of the server cabinet 1.

[0061] By setting the fixing mechanism 6, the position of the server unit mechanism 2 can be fixed, preventing the relative position of the server unit mechanism 2 and the server cabinet 1 from changing during operation, thus improving the stability of equipment operation; by using the sliding structure and the locking of the stop 601, the server unit mechanism 2 is prevented from sliding along the first direction after it is installed in place, thus fixing the server unit mechanism 2; by using the sliding structure to slidably connect with the server unit mechanism 2 along the second direction, the sliding structure can be disengaged from the stop 601 during the installation or disassembly of the server unit mechanism 2, facilitating the replacement and maintenance of the server unit mechanism 2.

[0062] In a specific implementation, the server unit mechanism 2 is provided with a fixing mechanism 6 on both sides of the second direction.

[0063] Preferably, the positioning slide rail 502 is also provided with a fixing block. The fixing block is located at one end of the slide rail near the liquid cooling mechanism 4. When the server unit mechanism 2 is installed in place and the sliding structure is locked with the stop block 601, the side of the slide plate near the liquid cooling mechanism 4 abuts against the fixing block. This can prevent the server unit mechanism 2 from continuing to move towards the side near the liquid cooling mechanism 4 in the first direction, and prevent the internal water supply pipe 402 and internal water return pipe 403 and other structures from being squeezed and deformed. This improves the stability of the connection between the first fixed pipe head 305 and the first movable pipe head 306, as well as the second fixed pipe head 308 and the second movable pipe head 309, and ensures the normal operation of the liquid cooling mechanism 4.

[0064] In one embodiment, the sliding structure includes an electric push rod 6021 and a sliding assembly 6022; the fixed end of the electric push rod 6021 is fixedly connected to the server unit mechanism 2; one end of the sliding assembly 6022 is fixedly connected to the driving end of the electric push rod 6021, and the other end is used to engage with the stop block 601.

[0065] By setting up the electric push rod 6021 and the sliding component 6022, both the sliding structure and the server unit mechanism 2 can be fixedly connected, and the sliding structure and the stop block 601 can be engaged. In addition, the electric push rod 6021 can also realize the automatic control of the sliding component 6022 when it slides in the second direction, which facilitates the installation and disassembly of the server unit mechanism 2.

[0066] In one embodiment, the sliding assembly 6022 includes a sliding chamber 60221, a sliding block 60222, and an elastic element 60223; the sliding chamber 60221 is fixedly connected to the drive end of the electric push rod 6021; one end of the sliding block 60222 is disposed inside the sliding chamber 60221, and the other end protrudes from the sliding chamber 60221 and is used to engage with the stop block 601; the elastic element 60223 is located inside the sliding chamber 60221, and both ends are fixedly connected to the sliding chamber 60221 and the sliding block 60222, respectively.

[0067] By setting the elastic element 60223, a sliding connection is achieved between the sliding block 60222 and the sliding chamber 60221. During the installation or disassembly of the server unit mechanism 2, the sliding block 60222 and the stop block 601 abut against each other and are pressed. Under the elastic force of the elastic element 60223, the sliding block 60222 moves towards the side closer to the sliding chamber 60221, avoiding interference between the sliding block 60222 and the stop block 601, which facilitates the installation and disassembly of the server unit mechanism 2. Furthermore, when the sliding block 60222 and the stop block 601 are locked together, the setting of the elastic element 60223 can also provide a buffer for the sliding block 60222, making the locking between the sliding block 60222 and the stop block 601 tighter.

[0068] In a specific implementation, the sliding block 60222 has a first guide surface at one end protruding from the sliding chamber 60221. The first guide surface is located on the side of the sliding block 60222 near the liquid cooling mechanism 4. The stop block 601 has a second guide surface, located on the side of the stop block 601 away from the liquid cooling mechanism 4. During the installation of the server unit mechanism 2, the first guide surface and the second guide surface slide together, the elastic element 60223 retracts, and the sliding block 60222 moves towards the side near the sliding chamber 60221 until the server unit mechanism 2 is installed in place. At this time, the sliding block 60222 is located on the side of the stop block 601 near the liquid cooling mechanism 4. At this time, the elastic element 60223 resets, and the sliding block 60222 is locked and fixed to the stop block 601.

[0069] Specifically, the first guide surface is an inclined surface, and the second guide surface is an arc-shaped surface.

[0070] In one embodiment, the server cabinet 1 further includes at least one sealing side plate 102, and the sealing side plate 102 is detachably connected to the support frame 101; the unit communication mechanism 3 is disposed on one side of the server cabinet 1 in the first direction, and the sealing side plate 102 is disposed on the side where the unit communication mechanism 3 is located.

[0071] By setting the unit connection mechanism 3 on one side of the server cabinet 1 in the first direction, the server unit mechanism 2 can slide relative to the server cabinet 1 in the first direction during the installation and disassembly of the server unit mechanism 2. Since the sealing side plate 102 is detachably connected to the support frame 101, it is convenient to maintain and replace the server unit mechanism 2 inside the server cabinet 1, thereby improving the stability and safety of the server unit mechanism 2.

[0072] In a specific embodiment, the support frame 101 is detachably connected to two sealing side plates 102 on both sides along the second direction; one sealing side plate 102 is detachably connected to one side of the support frame 101 along the first direction, and a fixing plate is connected to the other side. The sealing side plate 102 and the fixing plate can protect the interior of the server cabinet 1, and the sealing side plate 102 in the second direction also facilitates the maintenance or replacement of the fixing mechanism 6. Specifically, the fixing plate and the support frame 101 can be fixedly connected by welding or other methods, or detachably connected by fasteners such as screws.

[0073] In a specific embodiment, the server panel 204 is disposed on one side of the fixed plate and is fixedly connected to the support slide plate 501. The fixed plate is provided with a plurality of mounting holes in sequence, and the plurality of mounting holes correspond to the positions of the plurality of server panels 204, so that the server panels 204 can be observed from the outside of the server cabinet 1. Specifically, the server unit mechanism 2 also includes a handle, which is disposed on the side of the server panel 204. Pulling the handle can realize the sliding of the server unit mechanism 2 relative to the server cabinet 1 in a first direction. Specifically, pulling the handle can install and remove the server unit mechanism 2 from the mounting holes, which facilitates the installation and fixing of the server unit mechanism 2.

[0074] In a specific implementation, the server unit mechanism 2 is slidably installed into the server cabinet 1 via the positioning slide rail 502 and the support slide plate 501; the position of the server unit mechanism 2 is fixed by the engagement of the sliding block 60222 and the stop block 601; when the temperature sensing device inside the server module 201 detects that the temperature of the server module 201 is too high, the server panel 204 sends a signal to the intelligent cooling source module 401, and the intelligent cooling source module 401 controls the corresponding first solenoid valve 303 and second solenoid valve 304 to open, so that the corresponding first connecting branch pipe 301 and second... The connecting branch pipe 302 connects to the internal water supply pipe 402 via the intelligent cold source module 401, which delivers cold water from the external water supply pipe 406 to the internal water supply pipe 402. The cold water is then delivered to the finned condenser via the first connecting branch pipe 301 and the inlet pipe 2021, where it cools the server module 201. High-temperature water is then delivered to the internal return water pipe 403 via the outlet pipe 2022 and the second connecting branch pipe 302. The intelligent cold source module 401 then delivers the high-temperature water from the internal return water pipe 403 to the external return water pipe 407, which in turn delivers the high-temperature water to the outside. This invention enables cooling of a single server unit 2 and, when the server unit 2 is at a low temperature, closes the corresponding unit connection mechanism 3, reducing cold source loss, effectively improving energy efficiency, and lowering energy consumption.

[0075] Although embodiments of the invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the invention, and all such modifications and variations fall within the scope defined by the appended claims.
