Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology, specifically to a liquid pool and a liquid cooling cabinet. Background Technology

[0002] Immersion liquid cooling systems are commonly used for server heat dissipation. Coolant is introduced into the server through a distribution hole structure. The cooling liquid absorbs the heat generated by the equipment and carries the heat away through liquid flow or natural convection. The heat is then transferred to an external cooling system through a heat exchange device. This process can effectively reduce the temperature of the equipment and dissipate heat from the components inside the server.

[0003] However, because the server contains multiple components, the flow resistance of the coolant entering the server is greater than the flow resistance of the coolant entering the gap between the server and the coolant pool. This means that the coolant is more likely to flow away from the gap between the server and the coolant pool, resulting in a lower proportion of coolant entering the server, poor heat exchange efficiency, and inability to meet the heat dissipation requirements of high-power chips. Utility Model Content

[0004] This invention aims to address one of the technical problems in related technologies to a certain extent. To this end, this invention provides a liquid tank and a liquid-cooled cabinet, which has the advantages of increasing the proportion of coolant entering the server and improving heat dissipation efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coolant tank includes a cabinet with a receiving space for accommodating servers and coolant. The tank also includes a partition plate and at least one switch module. The partition plate is disposed within the receiving space and spaced apart from the bottom wall of the cabinet, forming a coolant inlet space. The partition plate has at least one opening penetrating through it, and each opening corresponds to a switch module. The switch module is used to open the corresponding opening when a server is mounted on the partition plate and to close the corresponding opening when no server is mounted on the partition plate. The partition plate divides the receiving space into a coolant inlet space and a server-accommodating space. The coolant inlet space allows coolant to enter the tank from the outside. The switch module controls whether coolant enters the server-accommodating space, specifically opening the corresponding opening when a server is mounted on the partition plate and closing it when no server is mounted on the partition plate. By connecting the server and the inlet space through the opening on the partition plate, the flow resistance of the coolant when entering the server is reduced, and the proportion of coolant entering the server in the total amount of coolant entering the liquid pool is increased. In other words, the flow rate of coolant inside the server is increased, the heat dissipation efficiency of the server is improved, and better heat dissipation effect is achieved.

[0007] Optionally, the switch module includes a switch plate and an operating mechanism, both located within the liquid inlet space. The switch plate covers the corresponding opening, and the operating mechanism is connected to the switch plate. The operating mechanism is used to move the switch plate away from the opening when a server is mounted on the partition plate, and to move the switch plate closer to the opening when the server is not mounted on the partition plate. Specifically, the operating mechanism in the switch module pushes the switch plate away from or closer to and against the partition plate, moving the switch plate away from the opening when a server is mounted on the partition plate, and moving the switch plate closer to the opening when the server is not mounted on the partition plate, thus allowing the coolant to be controlled by the switch module for inflow and outflow.

[0008] Optionally, the operating mechanism includes an elastic element and a push rod. The elastic element is fixedly connected to the switch plate, and the first end of the push rod is abutted against the switch plate. The second end of the push rod is fixedly connected to the server and can move with the server. The push rod and the elastic element are located on opposite sides of the switch plate. The push rod provides force when the switch plate moves away from the partition plate, and the elastic element provides force when the switch plate moves closer to the partition plate, enabling the switch plate to switch states. Furthermore, when no server is mounted on the partition plate, the switch plate is reset to a position close to and in contact with the partition plate, thus achieving an automatic reset function.

[0009] Optionally, the switch module further includes a support column located within the liquid inlet space. The first end of the support column is fixedly connected to the partition plate, and the second end passes through the switch plate and abuts against the bottom surface of the cabinet. The switch plate can slide along the support column. An elastic element is sleeved on the support column and located between the switch plate and the bottom surface of the cabinet. One end of the elastic element is fixed to the second end of the support column, and the other end is pressed against the switch plate. The support column limits the movement path of the switch plate, ensuring that the direction of movement is limited. By fixing the elastic element to the switch plate and allowing it to extend and retract along the support column, energy is stored as the switch plate is pushed away from the partition unit by the push rod. After the server leaves the partition unit, the energy is used to push the switch plate back into contact with the partition unit, reducing the amount of coolant flowing out of the liquid inlet space from the opening and increasing the proportion of coolant entering the server, thus achieving better heat dissipation.

[0010] Optionally, the server can switch between an installed state and a detached state. When the server is in the installed state, it is fixedly connected to the partition unit, the elastic element is compressed, at least a portion of the push rod extends into the liquid inlet space, and a gap is formed between the switch plate and the partition unit. When the server is in the detached state, it is away from the partition unit, the elastic element is at its maximum length, the push rod is outside the liquid inlet space, and the switch plate is in contact with the partition unit. When the server switches from the detached state to the installed state, it drives the push rod to move along a first direction, the push rod presses against the switch plate, and pushes the switch plate along the first direction, causing the elastic element to shorten under the pressure of the switch plate. When the server switches from the installed state to the detached state, it drives the push rod to move along a second direction, the elastic element applies a force along the second direction to the switch plate, pushing the switch plate to move along the second direction, causing the elastic element to extend. The first direction and the second direction are opposite. The connection between the server and the partition unit affects the distance between the switch plate and the partition unit through the push rods. Furthermore, the push rods and elastic elements on both sides of the switch plate provide opposing forces as it moves along the support column, thus enabling the switch plate to automatically reset after server removal. This ensures that the opening without the server installed has complete or almost no coolant flow. Specifically, when the server is not installed, the switch plate covers and seals the opening, preventing coolant from entering. When the server is installed, the push rods open the switch plate, creating a gap between the switch plate and the partition unit. Because the flow resistance of this gap to the coolant is less than the flow resistance of the gap between the server and the partition unit, a larger proportion of coolant enters through the opening, reducing the proportion of coolant that enters the server's space but not the server itself. This relatively increases the proportion of coolant entering the server, resulting in better heat dissipation efficiency.

[0011] Optionally, there may be multiple elastic elements and support columns, with each elastic element and support column corresponding to the other. The support columns are evenly distributed around the opening. The one-to-one correspondence between the support columns and elastic elements, with the elastic elements sleeved on the outside of the support columns and the support columns evenly distributed around the opening, ensures that the switch plate remains aligned with the opening during movement. Furthermore, due to the even distribution of the support columns, the elastic elements are also evenly distributed relative to the switch plate, resulting in a uniform distribution of the force applied by the elastic elements to the switch plate. This ensures that the switch plate remains parallel to the partition unit, preventing the switch plate from tilting and creating a gap between it and the partition unit, thus preventing coolant leakage.

[0012] Optionally, the liquid pool further includes a fixing module that covers the opening. The edge of the fixing module extends away from the partition plate. The server is fixed inside the fixing module, and the second end of the top rod is fixedly connected to the fixing module. The server is installed and connected to the partition unit via the fixing module. One side of the fixing module covers the opening to prevent coolant leakage from the opening portion extending beyond the edge of the fixing module after the server is installed in the partition unit. At the same time, the portion of the fixing module extending away from the partition plate fits against the outer surface of the server, preventing coolant from flowing out from the gap formed between the server and the fixing module, reducing the proportion of coolant not entering the server, and improving the heat dissipation effect.

[0013] Optionally, the push rod includes a connecting portion and a supporting portion. The connecting portion connects the supporting portion and the fixing module, and the supporting portion is used to abut against the switch plate. The edge of the supporting portion extends beyond the connecting portion, and the area of ​​the supporting portion in contact with the switch plate is located at the geometric center of the switch plate. The connecting portion connects the supporting portion and the fixing module and transmits the force applied by the fixing module. The edge of the supporting portion extends beyond the connecting portion, meaning the area of ​​the supporting portion is larger than the cross-sectional area of ​​the connecting portion. This allows the force applied by the push rod to be distributed more evenly over a wider area, reducing single-point pressure concentration, increasing the contact area between the push rod and the switch plate, improving stability, reducing the pressure between the push rod and the switch plate, preventing local deformation of the switch plate or damage to the push rod due to excessive pressure, and improving the safety of the switch module during use.

[0014] Optionally, the partition plate has multiple openings, and the fixing module covers at least one opening. The partition plate has multiple openings, allowing multiple servers to be installed in the coolant tank and used in parallel during operation, thus improving the compatibility and applicability of the coolant tank. Simultaneously, a single fixing module can cover multiple openings; the larger the total area of ​​the openings covered by a single fixing module, the greater the proportion of coolant entering the server, resulting in better heat dissipation for the server.

[0015] Optionally, the projected area of ​​the switch plate on the partition unit is greater than or equal to the cross-sectional area of ​​the opening, and when the switch plate is in close contact with the partition unit, the edge of the switch plate extends beyond the edge of the opening. The switch plate needs to seal the opening when the server is not installed on the partition unit, so the area of ​​the switch plate needs to be larger than the cross-sectional area of ​​the opening to ensure that coolant does not leak from the opening.

[0016] Optionally, the coolant pool includes an inlet pipe and an overflow tank. The inlet pipe connects the inlet space to the outside and is used for coolant entry. The overflow tank is located at the top of the cabinet and includes an outlet that connects the receiving space to the outside. The inlet is used to input coolant into the coolant pool, which then enters the server through the inlet space. Finally, after the coolant level rises to the overflow tank, it flows out of the coolant pool, forming a circulation.

[0017] This invention controls the amount of coolant entering the server and its proportion of the total coolant by using a switch board, thereby increasing the amount of coolant entering the server, increasing the coolant flow rate inside the server, improving heat exchange efficiency, and achieving better heat dissipation.

[0018] Furthermore, this utility model also provides a liquid-cooled cabinet, which includes a server and a liquid tank as described in any of the preceding claims. The liquid tank is used to house the server, and when the server is supported on the partition plate, it is completely located inside the liquid tank. The reasoning process for the beneficial effects of the liquid-cooled cabinet provided by this utility model is similar to that of the aforementioned liquid tank, and will not be repeated here.

Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described are intended to explain this utility model and should not be construed as limiting it.

[0027] The terms "an embodiment," "example," or "trademark" used in this specification refer to a particular feature, structure, or characteristic described in connection with the embodiment itself that may be included in at least one embodiment disclosed in this utility model. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0028] Example:

[0029] like Figures 1-3As shown, this utility model provides a liquid-cooled cabinet, which includes a liquid tank and a server. The liquid tank is used to accommodate the server, and when the server is supported on the partition plate 4, it is completely located inside the liquid tank. The liquid tank includes a cabinet body 1, and the cabinet body 1 forms a receiving space 11 for accommodating the server and coolant. The liquid tank also includes a partition plate 4 and at least one switch module 2. The partition plate 4 is disposed within the receiving space 11, and the partition plate 4 is spaced apart from the bottom wall of the cabinet body 1 to form a liquid inlet space 5. The partition plate 4 has at least one opening 41 that penetrates the partition plate 4. The opening 41 corresponds one-to-one with the switch module 2. The switch module 2 is used to open the corresponding opening 41 when the partition plate 4 is supporting a server, and to close the corresponding opening 41 when the partition plate 4 is not supporting a server. The partition plate 4 divides the accommodating space 11 into a liquid inlet space 5 and a space for accommodating the server. The liquid inlet space 5 is used for coolant to enter the liquid pool from the outside. The switch module 2 controls whether the coolant enters the space where the server is located. Specifically, the corresponding opening 41 is opened when the partition plate 4 is carrying the server, and closed when the partition plate 4 is not carrying the server. By connecting the server and the liquid inlet space 5 through the opening on the partition plate 4, the flow resistance of the coolant entering the server is reduced, the proportion of coolant entering the server in the total amount of coolant entering the liquid pool is increased, that is, the coolant flow rate inside the server is increased, the heat dissipation efficiency of the server is improved, and a better heat dissipation effect is achieved.

[0030] The switch module 2 includes a switch plate 21 and an operating mechanism 22, both located within the liquid inlet space 5. The switch plate 21 covers the corresponding opening 41. The operating mechanism 22 is connected to the switch plate 21. The operating mechanism 22 is used to move the switch plate 21 away from the opening 41 when a server is mounted on the partition plate 4, and to move the switch plate 21 closer to the opening 41 when the partition plate 4 is not carrying the server. Specifically, the operating mechanism 22 pushes the switch plate 21 away from or closer to and against the partition plate 4, moving it away from the opening 41 when a server is mounted on the partition plate 4, and moving it closer to the opening 41 when the partition plate 4 is not carrying the server, thus allowing the switch module 2 to control the inflow and outflow of coolant.

[0031] The operating mechanism 22 includes an elastic element 221 and a push rod 222. The elastic element 221 is fixedly connected to the switch plate 21. The first end of the push rod 222 is abutted against the switch plate 21, and the second end of the push rod 222 is fixedly connected to the server and can move with the server. The push rod 222 and the elastic element 221 are located on opposite sides of the switch plate 21. The push rod 222 provides force when the switch plate 21 is away from the partition plate 4, and the elastic element 222 provides force when the switch plate 21 is close to the partition plate 4, enabling the switch plate 21 to switch states and, when no server is supported on the partition plate 4, to reset the switch plate 21 to a position close to and in close contact with the partition plate 4, thus achieving an automatic reset function.

[0032] The switch module 2 further includes a support column 23 located within the liquid inlet space 5. The first end of the support column 23 is fixedly connected to the partition plate 4, and the second end of the support column 23 passes through the switch plate 21 and abuts against the bottom surface of the cabinet 1. The switch plate 21 can slide along the support column 23. The elastic element 221 is sleeved on the support column 23 and located between the switch plate 21 and the bottom surface of the cabinet 1. One end of the elastic element 221 is fixed to the second end of the support column 23, and the other end of the elastic element 221 is pressed and connected to the switch plate 21. The support column 23 is used to limit the movement path of the switch plate 21, ensuring that the movement direction of the switch plate 21 is limited. By fixing the elastic member 221 to the switch plate 21 and allowing the elastic member 221 to extend and retract along the support column 23, energy is stored during the process of the switch plate 21 being pushed away from the partition unit by the push rod 222. After the server leaves the partition unit, the switch plate 21 is pushed to re-adhere to the partition unit, reducing the amount of coolant flowing out of the liquid inlet space 5 from the opening 41, increasing the proportion of coolant entering the server, and obtaining a better heat dissipation effect.

[0033] The server can switch between an installed state and a disassembled state. In the installed state, the server is fixedly connected to the partition unit, the elastic element 221 is compressed, at least a portion of the push rod 222 extends into the liquid inlet space 5, and a gap is formed between the switch plate 21 and the partition unit. In the disassembled state, the server is away from the partition unit, the elastic element 221 is at its maximum length, the push rod 222 is outside the liquid inlet space 5, and the switch plate 21 is in contact with the partition unit. The server switches from the disassembled state to the installed state. In the installed state, the server drives the push rod 222 to move along the first direction X. The push rod 222 presses against the switch plate 21 and pushes the switch plate 21 along the first direction X. The elastic member 221 is shortened by the pressure of the switch plate 21. When the server switches from the installed state to the separated state, the server drives the push rod 222 to move along the second direction Y. The elastic member 221 applies a force along the second direction Y to the switch plate 21, pushing the switch plate 21 to move along the second direction Y. The elastic member 221 extends. The first direction X and the second direction Y are opposite. The connection between the server and the partition unit affects the distance between the switch plate 21 and the partition unit through the push rod 222. Furthermore, the push rods 222 and elastic elements 221 on both sides of the switch plate 21 provide opposite force during its movement along the support column 23, thereby enabling the switch plate 21 to automatically reset after server removal. This ensures that the opening 41 without the server installed has complete or almost no coolant flow. Specifically, when the server is not installed, the switch plate 21 covers and closes the opening 41, preventing coolant from entering. When the server is installed, the push rods 222 open the switch plate 21, creating a gap between the switch plate 21 and the partition unit. Since the flow resistance of this gap to the coolant is less than the flow resistance of the gap between the server and the partition unit, a larger proportion of coolant enters through the opening 41, reducing the proportion of coolant that enters the server's space but not the server itself. This relatively increases the proportion of coolant entering the server, resulting in better heat dissipation efficiency.

[0034] There are multiple elastic elements 221 and support columns 23, and each elastic element 221 and support column 23 corresponds to another. The support columns 23 are evenly distributed around the opening 41. The support columns 23 and elastic elements 221 correspond one-to-one, with the elastic element 221 sleeved on the outside of the support column 23. The support columns 23 are evenly distributed around the opening 41, ensuring that the switch plate 21 remains aligned with the opening 41 during movement. Furthermore, because the support columns 23 are evenly distributed, the elastic elements 221 are also evenly distributed relative to the switch plate 21, ensuring that the force applied by the elastic elements 221 to the switch plate 21 is evenly distributed. This guarantees that the switch plate 21 remains parallel to the partition unit and prevents the switch plate 21 from tilting, which could create a gap between it and the partition unit, leading to coolant leakage.

[0035] The liquid pool also includes a fixing module 3, which covers the opening 41. The edge of the fixing module 3 extends away from the partition plate 4. The server is fixed inside the fixing module 3, and the second end of the top rod 222 is fixedly connected to the fixing module 3. The server is installed and connected to the partition unit through the fixing module 3. One side of the fixing module 3 covers the opening 41 to prevent coolant leakage from the portion of the opening 41 that extends beyond the edge of the fixing module 3 after the server is installed in the partition unit. At the same time, the portion of the fixing module 3 extending away from the partition plate 4 is in contact with the outer surface of the server to prevent coolant from flowing out from the gap formed between the server and the fixing module 3, reducing the proportion of coolant that does not enter the server and improving the heat dissipation effect.

[0036] like Figure 4 As shown, the top rod 222 includes a connecting part 2221 and a supporting part 2222. The connecting part 2221 connects the supporting part 2222 and the fixing module 3. The supporting part 2222 is used to abut against the switch plate 21. The edge of the supporting part 2222 extends beyond the connecting part 2221. The area where the supporting part 2222 contacts the switch plate 21 is located at the geometric center of the switch plate 21. The connecting part 2221 is used to connect the support part 2222 and the fixing module 3, and to transmit the force applied by the fixing module 3. The edge of the support part 2222 extends beyond the connecting part 2221, that is, the area of ​​the support part 2222 is larger than the cross-sectional area of ​​the connecting part 2221, so that the force applied by the push rod 222 can be more evenly distributed to a wider area, reducing the phenomenon of single-point pressure concentration, increasing the contact area between the push rod 222 and the switch plate 21, improving stability, reducing the pressure between the push rod 222 and the switch plate 21, preventing the switch plate 21 from being locally deformed or damaged by the push rod 222 due to excessive pressure, and improving the safety of the switch module 2 during use.

[0037] The partition plate 4 has multiple openings 41, and the fixing module 3 covers at least one opening 41. The partition plate 4 has multiple openings 41, allowing multiple servers to be installed in the liquid tank and used in parallel, thus improving the compatibility and applicability of the liquid tank. Simultaneously, a single fixing module 3 can cover multiple openings 41; the larger the total area of ​​the openings 41 covered by a single fixing module 3, the greater the proportion of coolant entering the server, resulting in better heat dissipation for the server.

[0038] The projected area of ​​the switch plate 21 on the partition unit is greater than or equal to the cross-sectional area of ​​the opening 41. When the switch plate 21 is in close contact with the partition unit, the edge of the switch plate 21 extends beyond the edge of the opening 41. The switch plate 21 needs to seal the opening 41 when the server is not installed on the partition unit, so the area of ​​the switch plate 21 needs to be greater than the cross-sectional area of ​​the opening 41 to ensure that coolant does not leak from the opening 41.

[0039] The coolant pool includes an inlet pipe and an overflow tank. The inlet pipe connects the inlet space 5 to the outside and is used for coolant entry. The overflow tank is located on the top of the cabinet 1 and includes an outlet that connects the receiving space 11 to the outside. The inlet is used to input coolant into the coolant pool, which then enters the server through the inlet space 5. Finally, after the coolant level rises to the overflow tank, it flows out of the coolant pool, forming a circulation.

[0040] During use, the server can switch between an installed state and a detached state. When the server is in the installed state, it is fixedly connected to the partition plate 4, the elastic element 221 is compressed, at least part of the top rod 222 extends into the liquid inlet space 5, and a gap is formed between the switch plate 21 and the partition plate 4. When the server is in the detached state, it is away from the partition plate 4, the elastic element 221 is at its maximum length, the top rod 222 is located outside the liquid inlet space 5, and the switch plate 21 is in contact with the partition plate 4.

[0041] When the server switches from the detached state to the installed state, the server drives the push rod 222 to move along the first direction X. The push rod 222 presses against the switch plate 21 and pushes the switch plate 21 along the first direction X. The elastic member 221 is shortened by the pressure of the switch plate 21. When the server switches from the installed state to the detached state, the server drives the push rod 222 to move along the second direction Y. The elastic member 221 applies a force along the second direction Y to the switch plate 21, pushing the switch plate 21 to move along the second direction Y. The elastic member 221 extends. The first direction X and the second direction Y are opposite.

[0042] This invention controls the amount of coolant entering the server and its proportion of the total coolant through the switch board 21, thereby increasing the amount of coolant entering the server, increasing the coolant flow rate inside the server, improving heat exchange efficiency, and achieving better heat dissipation.

Those skilled in the art should understand that this utility model includes, but is not limited to, the contents described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
