Description

Technical Field

[0001] This utility model relates to the field of cooling technology for electronic equipment, specifically to a liquid-cooled cabinet and electronic equipment system. Background Technology

[0002] Liquid-cooled server racks are used to house electronic equipment. The operation of electronic equipment generates heat, and a cooling method is to use liquid as a heat dissipation medium to remove the heat from the equipment in the server rack.

[0003] Existing liquid-cooled cabinet heat dissipation technology mainly relies on the coolant directly contacting the surface of electronic equipment to transfer heat. However, due to the poor sealing of the cabinet, the coolant is prone to evaporation when in contact with the outside environment, and may even cause leakage. This sealing problem will greatly reduce the cooling effect of the cabinet, cause frequent equipment failures, damage data, and may also cause environmental pollution and other safety issues.

[0004] Therefore, how to optimize and improve the cabinet structure to give the cabinet good sealing performance, further reduce coolant evaporation and leakage, and improve the cabinet's safety and usability has become a technical problem that urgently needs to be solved in this field.

[0006] To achieve the above objectives, this utility model discloses a liquid-cooled cabinet, which includes a cabinet body and a power distribution unit. The power distribution unit is disposed on the side wall of the cabinet body. The liquid-cooled cabinet further includes:

[0007] At least one first sealing component is disposed on the side wall of the cabinet and penetrates the cabinet along the thickness direction. The first sealing component is located near one end of the power distribution unit and corresponds to the power distribution unit. The first sealing component is provided with a first through hole for the transmission line of the power distribution unit to pass through, so that the transmission line of the power distribution unit forms a sealed connection with the first sealing component.

[0008] Multiple second sealing components are disposed on the side wall of the cabinet and penetrate the cabinet along the thickness direction. The multiple second sealing components are arranged at intervals along the length direction of the cabinet. Each second sealing component has a second through hole for the transmission line of the electronic device of the cabinet to pass through, so that the transmission line of the electronic device of the cabinet forms a sealed connection with the second sealing component.

[0009] Furthermore, the diameter of the first perforation of the first sealing component is larger than the diameter of the second perforation of the second sealing component.

[0010] Furthermore, the diameter of the first perforation is between 15 mm and 22 mm, and the diameter of the second perforation is between 5 mm and 12 mm.

[0011] Furthermore, multiple second perforations are formed on the same second sealing assembly.

[0012] Furthermore, the liquid-cooled cabinet also includes a cable management rack, which is disposed opposite to the side wall of the cabinet. The cable management rack includes multiple cable management slots, which are arranged along the length of the cabinet. A cable management channel is formed between the multiple cable management slots and the side wall of the cabinet. The cable management channel is used to accommodate transmission lines, and the cable management slots are used to guide the transmission lines through. Multiple second sealing components correspond one-to-one with the multiple cable management slots.

[0013] Furthermore, the cabinet includes multiple power distribution units and multiple first sealing components, which are arranged adjacent to each other and correspond one-to-one with the multiple power distribution units.

[0014] Furthermore, the first sealing assembly and the second sealing assembly include a gland head, the gland head including a clamping nut, a clamping washer, a body, a sealing ring and a locking plate, the body penetrating the inner wall of the cabinet and being fixed by the sealing ring, the locking plate and the clamping nut, the clamping washer being disposed in the body, the clamping washer having a through hole, the through hole corresponding to the first through hole and / or the second through hole.

[0015] Furthermore, the material of the first sealing component and / or the second sealing component is selected from stainless steel, copper, and plastic.

[0016] As a second aspect disclosed in this application, an electronic device system is provided, including at least one electronic device, a transmission line, and a liquid-cooled cabinet. The electronic device is disposed in the liquid-cooled cabinet, which is the liquid-cooled cabinet described above. One end of the transmission line is electrically connected to the electronic device or a power distribution unit, and the other end of the transmission line passes through a first sealing component and a second sealing component and is electrically connected to an external power supply. The first through hole and the second through hole form a sealed connection between the corresponding transmission lines.

[0017] Furthermore, the electronic device system includes multiple electronic devices, each of which corresponds to a plurality of second sealing components. The multiple electronic devices are electrically connected to an external power supply via the transmission line passing through the corresponding plurality of second sealing components.

[0018] The beneficial effects of this utility model are:

[0019] The liquid-cooled cabinet provided by this utility model, by setting first and second sealing components in the cabinet, allows transmission cables to pass through the first and second through holes of the first and second sealing components.

Secondly, by setting first and second through holes at different positions in the cabinet for installing different sealing components, it is suitable for various installation application scenarios, making the cabinet more flexible and adaptable, and facilitating the installation of various types and locations of transmission cables. The first sealing component is positioned corresponding to the power distribution unit. The power distribution unit typically only has one power cable connected to the external power source. The placement of the first sealing component in the power distribution unit makes the power cable less prone to bending, hanging, and more securely fixed, resulting in a longer lifespan and higher safety. The rational layout also strengthens the seal of the power cable at the first perforation in the rack, preventing leakage caused by unstable movement of the power cable. The second sealing component is arranged at intervals along the length of the rack to facilitate the orderly and secure connection of multiple server cables, shortening the connection length within the rack and making it more robust and stable, further improving the seal. It also enables efficient cable management, avoiding cable clutter and improving the cleanliness and maintenance efficiency of the rack. The design of both the first and second sealing components adapts to different transmission line layouts within the rack, facilitating rack installation and disassembly, and promoting the modularity and scalability of the system.

[0020] These benefits enable liquid-cooled cabinets and electronic equipment systems to provide efficient cooling and protection while also offering good flexibility, adaptability, and reliability, making them suitable for modern data centers and other applications requiring efficient heat dissipation.

[0032] The embodiments of this utility model are described in detail below. 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.

[0033] The terms "an embodiment," "example," or "example" 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 application. The phrase "in an embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.

[0034] As the first aspect of this application, this utility model discloses a liquid-cooled cabinet, such as Figure 1 and Figure 2 As shown, the liquid-cooled cabinet includes a cabinet body 1 and a power distribution unit 4. The power distribution unit 4 is disposed on the side wall of the cabinet body 1. The liquid-cooled cabinet also includes:

[0035] At least one first sealing component 2a is provided on the side wall of the cabinet 1 and penetrates the cabinet 1 along the thickness direction. The first sealing component 2a is close to one end of the power distribution unit 4 and corresponds to the power distribution unit 4. The first sealing component 2a is provided with a first through hole 2a1 for the transmission line of the power distribution unit 4 to pass through, so that the transmission line of the power distribution unit 4 forms a sealed connection with the first sealing component 2a.

[0036] Multiple second sealing components 2b and multiple second sealing components 2a are disposed on the side wall of the cabinet 1 and penetrate the cabinet 1 along the thickness direction. Multiple second sealing components 2b are arranged at intervals along the length direction of the cabinet 1. The second sealing components 2b are provided with second through holes 2b1 for the transmission lines of the electronic equipment of the cabinet 1 to pass through, so that the transmission lines of the electronic equipment of the cabinet 1 form a sealed connection with the second sealing components 2b.

[0037] The liquid-cooled cabinet provided by this utility model, by setting first and second sealing components 2b in the cabinet, allows the transmission cable to pass through the first through hole 2a1 and the second through hole 2b1 of the first and second sealing components 2b. The sealing components can effectively fix and seal the transmission cable, and enhance the overall sealing performance of the cabinet, preventing the coolant from leaking or evaporating, and improving safety and protection capabilities. Secondly, by setting different sealing components in different positions of the cabinet, it is suitable for various installation application scenarios, making the cabinet more flexible and adaptable, and facilitating the installation of various types and positions of transmission cables. Among them, the first sealing component... The first sealing component 2a is positioned to correspond to the power distribution unit 4. The power distribution unit 4 typically only has one power line leading out to connect to the outside. The position of the first sealing component 2a is close to the power distribution unit 4, making the power line less prone to bending, hanging, and more secure, resulting in a longer service life and higher safety. The reasonable layout also makes the power line more airtight at the first through hole 2a1 of the cabinet, preventing leakage caused by unstable shaking of the power line. In some embodiments, the cabinet includes multiple power distribution units 4 and multiple first sealing components 2a. The multiple first sealing components 2a are arranged adjacent to each other and correspond one-to-one with the multiple power distribution units 4.

[0038] The second sealing component 2b is arranged at intervals along the length of the cabinet 1 to facilitate the orderly and secure connection of multiple server cables inside, shortening the connection length of the cables within the cabinet, making them more robust and stable, thereby further improving the sealing performance. It also enables efficient cable management, avoiding cable clutter and improving the cleanliness and maintenance efficiency of the cabinet. The design of the first sealing component 2a and the second sealing component 2b adapts to the different transmission line layouts required within the cabinet, facilitating cabinet installation and disassembly, and contributing to the modularity and scalability of the system.

[0039] This application does not impose special limitations on the spacing of the second sealing components 2b. In order to obtain better cable layout and sealing effect, in some embodiments, the second sealing components 2b are matched one-to-one with the servers they house. That is, the transmission lines of a server pass through the nearest second sealing component 2b and are sealed and fixed at the interface. This makes the distance of the server's transmission lines in the rack shorter, the cable arrangement more stable and firm and less prone to deformation and sagging, and also improves the sealing and fixing effect of the second sealing components 2b on the cables. In addition, setting the second sealing components 2b to be spaced out and matched one-to-one with the servers allows for more flexible and reasonable cable arrangement in the rack. In some embodiments, if the rack houses some servers, there will be idle second sealing components 2b. Therefore, these second sealing components 2b can be filled and sealed and not used. Only the second sealing components 2b corresponding to the positions where servers are housed will be used.

[0040] As an alternative implementation method, such as Figure 1 and Figure 2 As shown, the liquid-cooled cabinet also includes a cable management rack 3, which is disposed opposite to the side wall of the cabinet 1. The cable management rack 3 includes multiple cable management slots 3a, which are arranged along the length of the cabinet 1. A cable management channel is formed between the multiple cable management slots 3a and the side wall of the cabinet 1. The cable management channel is used to accommodate transmission lines, and the cable management slots 3a are used to guide the transmission lines through. Multiple second sealing components 2b correspond one-to-one with the multiple cable management slots 3a. In some embodiments, the data transmission line of each server is first embedded in its corresponding cable management slot 3a and fixed therein. The transmission line extending from the cable management slot 3a is further connected to the second sealing component 2b corresponding to each cable management slot 3a and passes through the cabinet 1 through the second sealing component 2b.

[0041] Preferably, the diameter of the first through hole 2a1 of the first sealing component 2a is larger than the diameter of the second through hole 2b1 of the second sealing component 2b. The first sealing component 2a is mainly used to connect the transmission line of the power distribution unit 4, which typically has a larger cable diameter. Therefore, the diameter of the first through hole 2a1 needs to be compatible with the size of the transmission cable of the power distribution unit 4. Preferably, the diameter of the first through hole 2a1 is between 15mm and 22mm. The second sealing component 2b is mainly used to connect the transmission line of the server, whose cable diameter is relatively smaller than that of the power cable. Correspondingly, the diameter of the second through hole 2b1 is also set to be smaller, but it needs to be compatible with the size of the server's transmission line. Preferably, the diameter of the second through hole 2b1 is between 5mm and 12mm.

[0042] In some embodiments, the server typically has multiple transmission lines. For ease of installation, the same second sealing component 2b includes multiple second through holes 2b1 for multiple transmission lines of the same server to pass through respectively.

[0043] As an alternative implementation method, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the first sealing assembly 2a and the second sealing assembly 2b include a gland head, which includes a clamping nut, a clamping washer, a body, a sealing ring, and a locking plate. The body penetrates the inner wall of the cabinet and is fixed by the sealing ring, the locking plate, and the clamping nut. The clamping washer is disposed in the body and has a through hole, which corresponds to the first through hole 2a1 and / or the second through hole 2b1. Using glands in immersion liquid-cooled cabinets offers numerous benefits. Glanders provide a reliable seal, preventing coolant leakage and external contaminants from entering the cabinet, ensuring safe and stable equipment operation. They securely hold cables in place, preventing movement or damage under liquid flow or other external forces, maintaining system stability. High-quality glands offer excellent waterproof and dustproof performance, effectively protecting internal electronic equipment from liquids and dust. In liquid-cooled environments, gland materials (such as stainless steel or chemical-resistant plastics) typically possess good corrosion resistance, withstanding long-term coolant exposure without corrosion. Glander designs generally prioritize ease of installation, allowing for quick and simple cable connection, saving installation time and reducing maintenance costs. Glanders are compatible with various cable specifications, offering good adaptability and versatility, allowing selection of appropriate models and sizes based on requirements. In summary, the application of gland heads in immersion liquid-cooled cabinets helps improve the reliability, security and ease of maintenance of the system, and is an important component to ensure the performance of the cabinet. As a preferred option, the first sealing component 2a is selected with a gland head of specification M30, and the second sealing component 2b is selected with a gland head of specification M20.

[0044] This application does not impose special limitations on the materials of the first sealing component 2a and the second sealing component 2b, as long as they meet the requirements of sealing and do not react with the cooling medium. Preferably, the materials of the first sealing component 2a and / or the second sealing component 2b are selected from stainless steel, copper, and plastic. In some embodiments, stainless steel glands are selected as sealing components. Stainless steel has excellent corrosion resistance and is suitable for use in environments where it comes into contact with humid or corrosive cooling media. Stainless steel is robust and durable, able to withstand mechanical shock and high pressure, allowing the gland to seal and fix the transmission line with greater tightening force. In addition, server racks typically operate at high temperatures during heat dissipation, and stainless steel maintains its stable physical properties even under high-temperature conditions. The advantages of selecting copper glands are that copper has excellent conductivity, making it suitable for applications requiring good electrical contact. Copper has natural antibacterial properties, making it less likely to contaminate the coolant inside the rack. Copper maintains good physical properties in specific environments and is easy to process. The advantages of choosing plastic glands are that plastic is lightweight, easy to install and handle, many plastics have good resistance to chemicals and are suitable for use in corrosive coolant environments, and plastic has good electrical insulation properties, making it suitable for applications requiring electrical insulation.

[0045] As a second aspect of this application, an electronic device system is provided, as shown in the figure, including at least one electronic device, a transmission line, and a liquid-cooled cabinet. The electronic device is disposed in the liquid-cooled cabinet, which is the liquid-cooled cabinet described above. One end of the transmission line is electrically connected to the electronic device or a power distribution unit, and the other end of the transmission line passes through a first sealing component and a second sealing component and is electrically connected to an external power supply. The first through hole and the second through hole form a sealed connection between the corresponding transmission lines.

[0046] The electronic equipment system includes multiple electronic devices, each corresponding to a number of second sealing components. The multiple electronic devices are electrically connected to an external power supply via transmission lines passing through the corresponding number of second sealing components.
