Abstract
Description
Technical Field
[0001] This utility model relates to the field of liquid cooling technology, specifically to an inner liner and a liquid cooling cabinet. Background Technology
[0002] With the rapid development of cloud computing, the demands on computing performance are increasing. While server performance is improving, power consumption is rising rapidly, with rack power consumption increasing exponentially. Consequently, the heat generated by servers during operation also increases.
[0003] To meet the heat dissipation requirements of high-power servers, liquid-cooled cabinets are generally used to dissipate heat and cool the servers through liquid cooling. However, the inner liner of these liquid-cooled cabinets is prone to leakage during use and has poor structural strength. Utility Model Content
[0004] This utility model aims to solve one of the technical problems in related technologies to a certain extent. To this end, this utility model provides an inner liner and liquid-cooled cabinet with better sealing performance and strength.
[0005] To achieve the above objectives, the first aspect of this utility model discloses an inner liner of a liquid-cooled cabinet. The inner liner includes a liner body, on which are formed a liquid inlet, a liquid outlet, and a receiving cavity for accommodating cooling medium and a server. The liquid inlet and the liquid outlet are respectively connected to the receiving cavity. The liner body includes a sealing layer and an inner shell and an outer shell nested together. The inner shell forms the receiving cavity. The liquid inlet and the liquid outlet respectively penetrate the inner shell and the outer shell. The liquid inlet is used to inject the cooling medium into the receiving cavity, and the liquid outlet is used to discharge the cooling medium from the receiving cavity. The outer shell is disposed outside the inner shell and is fixedly connected to the inner shell. A gap is formed between the outer shell and the inner shell, and the sealing layer is disposed within the gap.
[0006] In this technical solution, by setting the inner liner of the liquid-cooled cabinet to a double-layer structure (inner shell and outer shell), the structural strength of the inner liner itself can be greatly improved. In addition, by setting a sealing layer between the inner shell and the outer shell, a multi-layer stepped seal can be formed with the sealing structure of the inner shell and the outer shell itself, which improves the sealing performance of the inner liner and reduces the risk of leakage that may occur during use.
[0007] Furthermore, the top of the inner shell protrudes beyond the top of the outer shell and forms an opening structure. The inner shell has an overflow cavity and an overflow port. The overflow cavity is connected to the receiving cavity through the overflow port. One end of the liquid outlet is connected to the overflow cavity. The overflow port and the bottom wall of the inner shell are spaced at a set distance. The top of the outer shell is higher than the overflow port.
[0008] Furthermore, the inner shell includes an overflow channel plate, which is disposed within the inner shell. The overflow channel plate is fixedly disposed on the inner wall of the inner shell and together with the inner wall of the inner shell, forms the overflow cavity. The overflow outlet is disposed at the top of the overflow channel plate.
[0009] Furthermore, the bladder also includes multiple connectors, which are welded to the inner shell and the outer shell respectively to fix the inner shell and the outer shell. The multiple connectors are respectively arranged in different positions of the bladder and distributed at intervals.
[0010] Furthermore, the sealing layer fills the gap, the inner side of the sealing layer abuts against the outer wall of the inner shell, and the outer side of the sealing layer abuts against the inner wall of the outer shell.
[0011] Furthermore, the chamber also includes a buffer layer disposed within the interval, and the sealing layer and the buffer layer are nested within each other.
[0012] Furthermore, the interval between the inner shell and the outer shell is 5 mm to 10 mm.
[0013] Furthermore, the inner shell includes an inner bottom plate and a plurality of inner side plates disposed on the edge of the inner bottom plate. The inner side plates and the inner bottom plate are sealed and welded together. The plurality of inner side plates are sequentially sealed and welded around the periphery and together with the inner bottom plate, they limit the accommodating cavity.
[0014] Furthermore, a plurality of first concave-convex reinforcing portions are formed on the surface of the inner side plate, and the plurality of first concave-convex reinforcing portions are spaced apart; a plurality of second concave-convex reinforcing portions are formed on the inner bottom plate, and the plurality of second concave-convex reinforcing portions are spaced apart.
[0015] The second aspect of this utility model discloses a liquid-cooled cabinet, including an outer shell, an inner liner, and a refrigeration system. The inner liner is disposed inside the outer shell. The inner liner adopts the inner liner of the first aspect. The liquid inlet is connected to the output end of the refrigeration system through a liquid inlet pipe, and the liquid outlet is connected to the input end of the refrigeration system through a liquid outlet pipe.
[0016] The reasoning process for the beneficial effects of the liquid-cooled cabinet provided by this utility model and the aforementioned inner liner is similar, and will not be repeated here.

[0030] 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.
[0031] 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 one embodiment" appearing in various places throughout the specification does not necessarily refer to the same embodiment.
[0032] Liquid-cooled cabinets in related technologies generally consist of an inner liner (single-layer structure) and an outer shell, with the outer shell covering the inner liner. Although the outer shell and inner liner form a structure similar to a double layer, it is only similar in form. The outer shell only serves to house the inner liner and improve the product's appearance. The single-layer inner liner structure generally relies solely on the performance of its own components to ensure a sealing effect. Under prolonged pressure (the inner liner generally needs to contain a cooling medium of a certain depth during operation), it is prone to leakage risks.
[0033] Based on this, see Appendix Figures 1 to 5 The first aspect of this application discloses an inner liner of a liquid-cooled server rack. The inner liner 10 includes a liner body 11, on which a liquid inlet, a liquid outlet, and a receiving cavity 113 for accommodating cooling medium and a server are formed. The liquid inlet and the liquid outlet are respectively connected to the receiving cavity 113. The liner body 11 includes a sealing layer 114, and an inner shell 111 and an outer shell 112 nested together. The inner shell 111 forms the receiving cavity 113. The outer shell 112 is disposed outside the inner shell 111 and fixedly connected to the inner shell 111. The liquid inlet and the liquid outlet respectively penetrate the inner shell 111 and the outer shell 112. The liquid inlet is used to inject the cooling medium into the receiving cavity, and the liquid outlet is used to discharge the cooling medium from the receiving cavity. A gap is formed between the outer shell 112 and the inner shell 111, and the sealing layer 114 is disposed within the gap.
[0034] In this embodiment, the inner tank 10 is mainly used in liquid-cooled cabinets. Of course, in some specific environments, such as the testing or production stages, the inner tank 10 can also be used alone. In actual use, the inner tank 10 has a mounting bracket 15 for supporting the server in its receiving cavity 113. Cooling medium can be injected into the receiving cavity 113 of the inner tank 10 through the liquid inlet. During operation, the server is generally completely immersed in the cooling medium, that is, the liquid level of the cooling medium is generally higher than the top surface of the server.
[0035] To ensure good cooling performance, the cooling medium needs to be able to circulate, which helps to remove heat generated during server operation. In this embodiment, the cooling medium can circulate within the receiving cavity 113 by coordinating the outlet and inlet.
[0036] In actual design, the injection and discharge of cooling medium can be achieved by connecting the liquid outlet pipe 13 at the liquid outlet and the liquid inlet pipe 12 at the liquid inlet.
[0037] In this embodiment, the inner shell 10 is configured as an inner shell 111 and an outer shell 112 nested together to form a double-layer structure. In use, the inner shell 111 serves as a component for accommodating the server and cooling medium. In use, the inner shell 111 itself is a sealed structure, which can achieve sealing through its own structure to prevent leakage of the cooling medium.
[0038] In actual setup, the inner shell 111 can be set as a one-piece molded structure. However, in actual production, most inner shells 111 are formed by welding assembly (because the inner liner 10 is generally large in volume, and the difficulty and cost of one-piece molding are relatively high). During the assembly process, the sealing performance of the mating parts can be ensured by controlling the welding quality.
[0039] In this embodiment, the size of the gap between the inner shell 111 and the outer shell 112 is not specifically limited. In actual setting, it can be set according to actual needs (taking into account production cost, strength and selection of sealing materials, etc.), and can generally be set to 5mm to 10mm.
[0040] It should be noted that in this embodiment, the cross-section of the gap between the inner shell 111 and the outer shell 112 is U-shaped, see Appendix. Figure 1 That is, there are gaps between the corresponding side plates and bottom plates of the inner shell 111 and the outer shell 112.
[0041] In this embodiment, the sealing layer 114 can fill the entire gap, or it can be set only in a part of the gap. In actual use, the sealing layer 114 can be made of nano silicone or other sealing materials.
[0042] In this embodiment, the connection method between the inner shell 111 and the outer shell 112 is not specifically limited. The inner shell 111 and the outer shell 112 can be connected by the connector 116, or by setting mutually cooperating parts on their respective structures, and then connected by snap-fit or plug-in. Of course, they can also be directly welded together.
[0043] In this embodiment, the relative size of the outer shell 112 and the inner shell 111 is not specifically limited. In actual installation, the inner shell 111 can be completely placed inside the outer shell 112, or only partially placed inside the outer shell 112.
[0044] Compared to the single-layer inner liner 10 in related technologies, the double-layer inner liner 10 in this embodiment achieves the same strength. For example, in related technologies, to ensure the strength of the single-layer inner liner 10, the wall thickness of the inner liner 10 is generally set to a thicker solid structure (5mm to 10mm), and reinforcing ribs are also added. This will undoubtedly greatly increase the weight and production cost of the inner liner 10.
[0045] In this embodiment, the inner shell 111 can be made of corrugated stainless steel plate. The corrugated structure, through physical forming (such as stamping), significantly improves the rigidity and load-bearing capacity of the plate, and can withstand greater pressure even when the thickness is relatively thin. The outer shell 112 can be made of flat steel plate, which can improve the overall appearance of the product.
[0046] In this embodiment, the combination of two thin-walled components (inner shell 111 and outer shell 112) with the structure of the sealing layer 114 can improve sealing performance and strength, and reduce production costs.
[0047] In this embodiment, the inner liner 10 may also include a flow equalization pipe 14, which is disposed at the bottom of the inner shell 111. The liquid inlet is connected to the flow equalization pipe 14, which extends along the length of the inner liner 10. The side wall of the flow equalization pipe 14 is provided with a plurality of liquid distribution ports 141 spaced apart along the axial direction of the flow equalization pipe 14. In this way, when the cooling medium is injected into the receiving cavity 113, the cooling medium can flow out from the plurality of liquid distribution ports 141 respectively, so that the distribution of the cooling medium with a lower temperature in the receiving cavity 113 is more uniform, which helps to improve the uniformity of heat dissipation.
[0048] As one embodiment of this utility model, see the appendix. Figure 1 and Figure 5 The top end of the inner shell 111 protrudes beyond the top end of the outer shell 112 and forms an opening structure. The inner shell 111 has an overflow cavity 1111 and an overflow port 1151. The overflow cavity 1111 is connected to the receiving cavity 113 through the overflow port 1151. The liquid outlet is connected to the overflow cavity 1111. The overflow port 1151 is spaced at a predetermined distance from the bottom wall of the inner shell 111. The top end of the outer shell 112 is higher than the overflow port 1151.
[0049] In this embodiment, only a portion of the bottom side of the inner shell 111 is disposed inside the outer shell 112. Since the bottom side of the inner liner 10 needs to withstand greater pressure during use and transportation, the bottom side of the inner shell 111 can be strengthened by placing the outer shell 112 outside the bottom side of the inner shell 111. Moreover, the height of the outer shell 112 is smaller than that of the inner shell 111, which greatly reduces the amount of material used and saves costs.
[0050] In this embodiment, the lower limit of the height of the outer shell 112 is also limited. The top of the outer shell 112 is not lower than the height of the overflow port 1151. Since the height of the overflow port 1151 is generally level with the liquid level of the cooling medium in the inner liner 10, the part of the inner shell 111 below the height of the overflow port 1151 needs to bear the function of containing the cooling medium. Therefore, setting the height of the outer shell to be higher than the height of the overflow port 1151 can effectively strengthen the strength and seal of the part of the inner shell 111 that contains the cooling medium.
[0051] In actual installation, the top of the outer shell 112 can be provided with an inwardly bent plate, so that the bent plate is attached to and welded to the outer wall of the inner shell 111, thereby achieving the closure of the top of the gap between the inner shell 111 and the outer shell 112.
[0052] As one embodiment of this utility model, see the appendix. Figure 1 The inner shell 11 includes an overflow channel plate 115, which is disposed inside the inner shell 111. The overflow channel plate 115 is fixedly disposed on the inner wall of the inner shell 111 and together with the inner wall of the inner shell 111, forms the overflow cavity 1111. The overflow port 1151 is disposed on the top of the overflow channel plate.
[0053] In this embodiment, the overflow trough plate 115 is an L-shaped plate structure. In actual use, the overflow trough plate 115 is welded to the inner wall of the inner shell 111 to form an overflow cavity 1111. A mounting platform with its surface facing upward protrudes from the inner wall of the inner shell 111. The two ends of the overflow trough plate 115 are welded to the side walls of the mounting platform at both ends. The two sides of the overflow trough plate 115 are welded to the inner wall of the inner shell 111 and the top surface of the mounting platform, respectively, thus forming the structure of the overflow cavity 1111. By opening an overflow port 1151 on the overflow trough plate 115, the cooling medium can easily enter the overflow cavity 1111 through the overflow port 1151 and finally be discharged through the liquid outlet (liquid outlet pipe 13).
[0054] As one embodiment of this utility model, see the appendix. Figure 3The bladder body 11 also includes a plurality of connectors 116, which are welded to the inner shell 111 and the outer shell 112 respectively to fix the inner shell 111 and the outer shell 112. The plurality of connectors 116 are respectively arranged in different positions of the bladder body 11 and are distributed at intervals.
[0055] In this embodiment, the inner shell 111 and the outer shell 112 are connected by a connector 116. The connector 116 can be a sealing stud. During use, the two ends of the sealing stud can be welded to the inner shell 111 and the outer shell 112 respectively, serving both as a connector and helping to ensure the sealing effect of the connection. In addition, the connector 116 in this embodiment can also support the inner shell 111 and the outer shell 112, preventing local deformation of the inner shell 111 and the outer shell 112 under stress during use and maintaining the consistency of the spacing between the inner shell 111 and the outer shell 112. In actual installation, to ensure a more stable connection, the number of connectors 116 can be set to multiple. Each pair of opposite side plates and bottom plates of the inner shell 111 and the outer shell 112 can be welded together by multiple connectors 116.
[0056] In actual installation, the connector 116 is located between the inner shell 111 and the outer shell 112, and generally does not protrude from the surfaces (visible surfaces) of the inner shell 111 and the outer shell 112, making the overall appearance more aesthetically pleasing.
[0057] As one embodiment of this utility model, see the appendix. Figure 1 and Figure 2 The sealing layer 114 fills the gap, the inner side of the sealing layer 114 abuts against the outer wall of the inner shell 111, and the outer side of the sealing layer 114 abuts against the inner wall of the outer shell 112.
[0058] In this embodiment, the sealing layer 114 fills the gap. The sealing layer 114 can be made of nano silicone, which not only maximizes the thickness of the sealing layer 114 and improves the sealing effect, but also the sealing layer 114 (taking nano silicone as an example) can absorb the difference in thermal expansion, reduce the risk of weld cracking (inner shell 111 and outer shell 112), and of course, it can also play an auxiliary support role, improving the structural strength of the inner liner 10.
[0059] In one embodiment of the present invention, the bladder body 11 further includes a buffer layer, which is disposed within the interval, and the sealing layer 114 and the buffer layer are nested together.
[0060] When the gap between the inner shell 111 and the outer shell 112 is large, a buffer layer can be provided within the gap. The buffer layer can be an elastic gasket made of fluororubber, which is generally placed on the outside of the sealing layer 114 to better absorb the squeezing and impact from the outside of the inner liner 10. Of course, the buffer layer can also be placed on the inside of the sealing layer 114 as needed.
[0061] As one embodiment of this utility model, see the appendix. Figure 4 The inner shell 111 includes an inner bottom plate 1112 and a plurality of inner side plates 1113 disposed on the edge of the inner bottom plate 1112. The inner side plates 1113 and the inner bottom plate 1112 are sealed and welded together. The plurality of inner side plates 1113 are sequentially sealed and welded around the periphery, and together with the inner bottom plate 1112, they limit the cavity 113.
[0062] In this embodiment, the inner shell 111 generally includes an inner bottom plate 1112 and four inner side plates 1113. When assembling the components, key stress points can be fixed by laser spot welding with a weld spacing of 50mm. The perimeter is sealed by continuous argon arc welding. After welding, the components are polished to improve the sealing effect.
[0063] The inner liner 10 in this embodiment has a 20-40% higher compressive strength than the inner liner 10 in related technologies, and a leakage rate of ≤0.01L / h, thus achieving the dual goals of improved sealing and strength.
[0064] To further improve the strength of the inner liner 10, in one embodiment of this application, a plurality of first concave-convex reinforcing portions 1114 are formed on the surface of the inner side plate 1113, and the plurality of first concave-convex reinforcing portions 1114 are spaced apart; a plurality of second concave-convex reinforcing portions 1115 are formed on the inner bottom plate 1112, and the plurality of second concave-convex reinforcing portions 1115 are spaced apart.
[0065] As attached Figure 1 , 4 As shown in Figure 5, in this embodiment, reinforcing structures can be formed on the inner bottom plate 1112 and the inner side plate 1113 respectively. The first concave-convex reinforcing part 1114 and the second concave-convex reinforcing part 1115 can be formed by stamping. Moreover, in actual installation, the multiple first concave-convex reinforcing parts 1114 on the inner bottom plate 1112 can be set as honeycomb to further improve the strength.
[0066] This embodiment forms a reinforced structure with concave and convex features on the surface of a thin-walled component through physical structure. Compared with the reinforcing ribs in related technologies, this reduces weight and facilitates production.
[0067] The second aspect of this utility model discloses a liquid-cooled cabinet, including an outer shell, an inner liner 10, and a refrigeration system. The inner liner 10 is disposed inside the outer shell. The inner liner 10 adopts the inner liner 10 of the first aspect. The liquid inlet is connected to the output end of the refrigeration system through a liquid inlet pipe 12, and the liquid outlet is connected to the input end of the refrigeration system through a liquid outlet pipe 13.
[0068] In this embodiment, the inner liner 10 is also provided with an outer shell. The double-layer structure of the inner liner 10, combined with the structure of the outer shell, allows the liquid cooling mechanism to have a more layered structure, improving sealing performance and strength.
[0069] The above are merely specific embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. 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.
