Description

Technical Field

[0001] This application relates to the technical field of servers, and particularly to a server and a liquid-cooled hard disk enclosure. Background Art

[0002] Servers are widely adopted due to their compactness and high-density deployment.

[0003] In related technologies, the deployment density is improved by adjusting the hard disk layout. For example, a side heat dissipation design is adopted to narrow the hard disk spacing. However, although this design can increase the hard disk deployment density, the heat dissipation efficiency is significantly reduced due to the narrow side heat dissipation channel, affecting the stability and lifespan of the device. There are also cases where multiple hard disks are vertically stacked in a containing space to save space, but this structure easily leads to heat accumulation in the middle of the chassis, and it is necessary to rely on complex air ducts or additional heat dissipation devices, which not only increases the system complexity but also makes it difficult to achieve uniform heat dissipation.

[0004] Therefore, in a limited height space, how to ensure heat dissipation performance while increasing the hard disk deployment density has become an urgent problem to be solved. Summary of the Invention

[0005] Embodiments of this application provide a server and a liquid-cooled hard disk enclosure, which can reduce the thickness of the cold plate and improve the hard disk deployment density while ensuring the heat dissipation efficiency.

[0006] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0007] In a first aspect, embodiments of this application provide a server, including:

[0008] At least two cold plates that are spaced apart and oppositely arranged, with a cooling cavity integrally formed inside the cold plates, and the cooling cavity is for the coolant to flow through; a containing cavity is formed between the at least two cold plates, and the containing cavity is used for inserting a hard disk module so that the heat of the hard disk module is transferred to the coolant in the cooling cavity;

[0009] An inlet water distributor, the inlet end of the cooling cavity is connected to the flow channel of the inlet water distributor so that the coolant flows into the cooling cavity from the inlet water distributor;

[0010] An outlet water distributor, the outlet end of the cooling cavity is connected to the flow channel of the outlet water distributor so that the coolant flowing through the cooling cavity is collected by the outlet water distributor;

[0011] Wherein, the at least two cold plates are connected between the inlet water distributor and the outlet water distributor.

[0012] It can be understood that the cooling cavity is integrally formed inside the cold plate, which can be understood as the cooling cavity inside the cold plate is formed by enclosing the plate body of the cold plate.

[0013] At least two cold plates of the server provided by the embodiments of the present application are connected between the inlet water distributor and the outlet water distributor. Thus, the inlet water distributor and the outlet water distributor not only serve as channels for the inflow and outflow of the coolant, but also support at least two cold plates, so that the at least two cold plates are arranged at intervals to form a receiving cavity. That is to say, the inlet water distributor, the outlet water distributor and at least two cold plates constitute a framework for forming the receiving cavity. Through the above structural arrangement, the overall architecture is simplified and miniaturization is achieved. In addition, the cooling cavity of the cold plate is obtained by integral molding, and the cooling cavity can be formed within the thickness dimension of the plate material for making the cold plate, thereby reducing the thickness dimension of the cold plate and avoiding the problem that a relatively thick cold plate occupies a large height space. Therefore, within the same height space, there is more space for accommodating the hard disk module, thereby improving the deployment density of the hard disk module, that is, the hard disk.

[0014] In addition, based on the principle that there is a contact thermal resistance between dissimilar materials, and the contact thermal resistance will reduce the heat transfer efficiency at the contact surface of dissimilar materials, there is no contact thermal resistance between the cooling cavity obtained by integral molding and the plate body of the cold plate, so as to ensure the heat transfer efficiency from the hard disk module to the coolant, thereby improving the heat dissipation efficiency of the hard disk module.

[0015] In one implementation, the cooling cavity is configured to be obtained by extrusion molding or blow molding;

[0016] In the case where the cooling cavity is obtained by blow molding, the cold plate includes a first part and a second part. The first part is connected to both sides of the second part along the direction in which the hard disk module is inserted into the receiving cavity, and the second part is used for blow molding to form the cooling cavity.

[0017] In the embodiments of the present application, the cooling cavity is formed by blowing with high-pressure gas, the height of the cooling cavity is reduced, the structure is compact, and thus the thickness of the cold plate is reduced; the height space of the server is saved, and the space for deploying the hard disk in the server is improved. In addition, after the cooling cavity is communicated with the inlet water distributor and the outlet water distributor, the overall sealing performance is strong and the risk of liquid leakage is low.

[0018] In one implementation, the second part has a first wall and a second wall oppositely arranged along the thickness direction of the cold plate, and support columns extending along the thickness direction of the cold plate are arranged between the first wall and the second wall.

[0019] In the embodiments of the present application, the support columns are arranged between the first wall and the second wall, so that when the cold plate is subjected to an external force, the force can be dispersed to multiple support columns, thereby effectively resisting the deformation caused by the insertion and extraction of the hard disk and vibration, ensuring the structural strength of the cold plate, and ensuring the long-term stable operation of the server.

[0020] In one implementation, there are multiple support columns, and the multiple support columns are arranged in a staggered manner along the flow direction of the coolant in the second part.

[0021] In the embodiments of the present application, multiple support columns are arranged staggeredly in the second part along the flow direction of the coolant, which can reduce the number of support columns arranged in the flow direction of the coolant, thereby reducing the resistance generated by the support columns to the flow of the coolant and ensuring the flow efficiency of the coolant.

[0022] In one implementation, partition ribs extending along the flow direction of the coolant are formed inside the cold plate, and the partition ribs penetrate the cooling cavity along the thickness direction of the cold plate, dividing the cooling cavity into multiple sub-cooling cavities extending along the flow direction of the coolant.

[0023] In the embodiments of the present application, the partition ribs, as a through-type strengthening structure, enhance the bending resistance of the cold plate, can effectively resist the impact during hard disk insertion and vibration, and ensure the structural strength and thermal conduction stability of the cold plate. In addition, the partition ribs divide the cooling cavity into multiple sub-cooling cavities extending along the flow direction of the coolant, thereby increasing the contact area between the coolant and the inner wall of the sub-cooling cavity, and thus increasing the heat transfer area between the cold plate and the coolant, effectively improving the heat dissipation efficiency of the hard disk module.

[0024] In one implementation, in the direction in which the hard disk module is inserted into the accommodating cavity, the size of the cooling cavity is greater than or equal to the size of the hard disk module.

[0025] In the embodiments of the present application, for the integrally formed cooling cavity, in the direction in which the hard disk module is inserted into the accommodating cavity, the size of the cooling cavity is greater than or equal to the size of the hard disk module, so that the heat transfer area between the cooling cavity and the hard disk module is increased, the heat absorption efficiency of the coolant is increased, and thus the heat dissipation efficiency is improved.

[0026] In one implementation, in the flow direction of the coolant, the ratio of the flow cross-sectional area of the cooling cavity to the cross-sectional area of the cold plate is 3:10 to 3:5.

[0027] In the embodiments of the present application, the cooling cavity is integrally formed, so that the proportion of the flow cross-sectional area of the cooling cavity in the cross-sectional area of the cold plate is 3 / 10 to 3 / 5, increasing the proportion space of the cooling cavity, increasing the flow rate of the coolant, and effectively improving the heat dissipation efficiency of the hard disk module.

[0028] In one implementation, the thickness dimension of the cold plate is 1 mm to 2 mm (including 1 mm and 2 mm).

[0029] In the embodiments of the present application, the thickness dimension of the cold plate can be reduced to 1 mm to 2 mm, avoiding the problem that a relatively thick cold plate occupies a large height space. Therefore, in the same height space, more space can be used to accommodate the hard disk module, thereby increasing the deployment density of the hard disk module, that is, the hard disk. It should be noted that the thickness of the cold plate is the thickness of the cold plate along at least two directions in which the cold plates are spaced apart.

[0030] In one implementation, the server further includes a middle partition plate, which is inserted between adjacent cold plates to form at least two accommodating cavities distributed along the first direction of the cold plate between the adjacent cold plates.

[0031] In the embodiments of the present application, by introducing the middle partition plate, a plurality of accommodating cavities with different sizes are divided between adjacent cold plates, and hard disk modules with different sizes can be inserted, thereby improving the adaptability of the accommodating cavities.

[0032] In one implementation, the middle partition plate is spaced apart to form a first abutting portion and a second abutting portion along the direction in which the hard disk module is inserted into the accommodating cavity, and the cold plate has a first side wall and a second side wall arranged oppositely along the direction in which the hard disk module is inserted into the accommodating cavity;

[0033] The first abutting portion abuts against the first side wall;

[0034] The second abutting portion abuts against the second side wall.

[0035] In the embodiments of the present application, the first abutting portion and the second abutting portion formed at intervals along the direction in which the hard disk module is inserted into the accommodating cavity of the middle partition plate abut against the first side wall and the second side wall of the cold plate, so as to realize the stability of the middle partition plate inserted between adjacent cold plates; there is no need to add additional fixing parts, which simplifies the structural design and reduces the manufacturing cost.

[0036] In one implementation, both the first abutting portion and the second abutting portion are formed by protruding outward from one side wall of the middle partition plate along the thickness direction of the cold plate.

[0037] In one implementation, a first recessed portion is formed by inwardly recessing the first surface of the cold plate along the direction in which the hard disk module is inserted into the accommodating cavity, and the bottom wall of the first recessed portion serves as the first side wall;

[0038] A second recessed portion is formed by inwardly recessing the second surface of the cold plate along the direction in which the hard disk module is inserted into the accommodating cavity, and the bottom wall of the second recessed portion serves as the second side wall, wherein the first surface and the second surface are arranged oppositely.

[0039] In the embodiments of the present application, the first side wall is recessed in the first surface, and the second side wall is recessed in the second surface, which is convenient for positioning when the first abutting portion abuts against the first side wall or the second abutting portion abuts against the second side wall, and the first abutting portion and the second abutting portion are not easy to slide along the first direction of the cold plate, thereby improving the stability of the middle partition plate inserted between adjacent cold plates.

[0040] In one implementation, the surface of the inlet end of the cold plate extends outward to form a first plugging portion, and the surface of the inlet water distributor for communicating with the inlet end is inwardly recessed to form a first insertion portion, and the first plugging portion is located within the first insertion portion, wherein the contour dimensions of the first plugging portion and the second insertion portion match;

[0041] The outlet end surface of the cold plate extends outward to form a second plug-in portion, and the surface of the outlet water distributor used to communicate with the outlet end is recessed inward to form a second insertion portion, and the second plug-in portion is located in the second insertion portion, wherein the second plug-in portion matches the contour size of the second insertion portion.

[0042] In the embodiment of the present application, the first plug-in portion is plugged into the first insertion portion, and the second plug-in portion is plugged into the second insertion portion, so as to achieve convenient installation between the cold plate and the inlet water distributor, and the outlet water distributor, and at the same time achieve efficient communication between the cooling chamber and the flow channels of the inlet water distributor and the outlet water distributor.

[0043] In one implementation, the cold plate and the inlet water distributor are sealed and connected at the plug-in joint by a seal; or,

[0044] The cold plate and the outlet water distributor are sealed and connected at the plug-in joint through a sealing member.

[0045] In the embodiment of the present application, the cold plate and the imported water distributor are sealed and connected at the plug-in joint by a seal, thereby eliminating the need to achieve a sealed connection through an interference fit between the first plug-in portion and the first insertion portion, thereby reducing the difficulty of assembly and ensuring the sealing of the connection between the cold plate and the imported water distributor.

[0046] In one implementation, the sealing member is configured as solder or adhesive; the solder or adhesive fills the plug-in gap between the first plug-in portion and the first insertion portion; or,

[0047] The solder or adhesive fills the insertion gap between the second insertion portion and the second insertion portion.

[0048] In one implementation, the hard disk module includes a hard disk and a liquid-cooled hard disk bracket, the liquid-cooled hard disk bracket has a loading cavity, and the hard disk is loaded in the loading cavity; the liquid-cooled hard disk bracket is inserted in the accommodating cavity;

[0049] The server further comprises an elastic member, which is arranged between the hard disk and the cold plate to achieve elastic contact between the hard disk and the cold plate.

[0050] In the embodiment of the present application, an elastic member is placed between the hard disk and the cold plate to achieve elastic contact between the hard disk and the cold plate, thereby increasing the contact area between the hard disk and the cold plate, thereby increasing the heat transfer area and increasing the heat dissipation efficiency of the hard disk.

[0051] In one implementation, the server further includes a bracket, the bracket is placed between the hard disk and the cold plate, and the elastic member is arranged on a side of the bracket facing the hard disk and / or the cold plate.

[0052] In the embodiment of the present application, a bracket and an elastic member are provided between the cold plate and the hard disk. By using the elastic effect of the elastic member, elastic contact between the cold plate and the hard disk is achieved. In addition, when the elastic member loses its elasticity and needs to be replaced, only the bracket needs to be replaced, which reduces the impact on other structures and is beneficial to later maintenance.

[0053] In one implementation, the elastic member is configured as an elastic convex hull, and the elastic convex hull is formed by protruding outward from the surface of the bracket; the top surface of the elastic convex hull is used to contact the hard disk or the cold plate.

[0054] In the embodiment of the present application, the structural design of integrally forming the elastic convex hull can simplify the manufacturing process, reduce costs, avoid the problem of gaps between the elastic convex hull and the bracket, and achieve the stability of the elastic connection between the elastic convex hull, the hard disk and the cold plate.

[0055] In one implementation, a concave pit is formed in the area of the bracket facing away from the elastic convex hull; a heat-conducting pad is provided in the concave pit;

[0056] When the top surface of the elastic convex hull is used to contact the hard disk, the side of the heat-conducting pad facing away from the concave pit is used to contact the cold plate; or,

[0057] When the top surface of the elastic convex hull is used to contact the cold plate, the side of the heat-conducting pad facing away from the concave pit is used to contact the hard disk.

[0058] In the embodiment of the present application, the heat-conducting pad is used to fill the gap between the bottom of the concave pit and the cold plate or the hard disk in the z direction of the cold plate thickness, so as to enable heat transfer between the hard disk module and the coolant along the z direction of the cold plate thickness, shorten the heat transfer path, and improve the heat dissipation efficiency.

[0059] In one implementation, the bracket and the cold plate are connected to the surface for dissipating heat of the hard disk module, and the top surface of the elastic convex hull faces the accommodation cavity, and the heat-conducting pad contacts the cold plate.

[0060] In the embodiment of the present application, the bracket is directly provided on the cold plate, which can support the hard disk module to be directly inserted into the accommodation cavity and directly cooled by water.

[0061] In one implementation, the liquid-cooled hard disk bracket has a plate surface in the thickness direction of the cold plate, through holes are formed in the plate surface, the bracket is connected to the side of the plate surface facing the loading cavity, and the elastic convex hull protrudes from the through holes, and the heat-conducting pad contacts the hard disk.

[0062] In the embodiment of the present application, the bracket is connected to the liquid-cooled hard disk bracket, and the plate surface can press around the concave pit, thereby preventing the heat-conducting pad from overflowing during the forming process, which is beneficial to improving the efficiency and quality of setting the heat-conducting pad.

[0063] In one implementation, the surface of the side of the heat-conducting pad facing away from the concave pit exceeds the surface of the first bracket facing away from the elastic convex hull.

[0064] In the embodiment of the present application, by configuring the surface of the heat-conducting pad facing away from the pit to exceed the surface of the first bracket facing away from the elastic convex hull, it is ensured that the side of the heat-conducting pad facing away from the pit can stably contact the cold plate or the hard disk.

[0065] In one implementation, the top surface of the elastic convex hull or the side of the heat-conducting pad facing away from the pit contacts the heat dissipation teeth of the hard disk.

[0066] In the embodiment of the present application, the heat of the hard disk is transferred to the elastic convex hull or the heat-conducting pad through the heat dissipation teeth. Without changing the heat dissipation structure of the hard disk, the liquid cooling system provided by the embodiment of the present application can be applied, thereby expanding the applicable scenarios of the server.

[0067] In a second aspect, the embodiment of the present application provides a liquid-cooled hard disk enclosure, including:

[0068] At least two cold plates arranged at intervals and opposite to each other, with a cooling cavity integrally formed inside the cold plates for the coolant to flow through; a receiving cavity is formed between the at least two cold plates for inserting a hard disk module;

[0069] An inlet water distributor, the inlet end of the cooling cavity is connected to the flow channel of the inlet water distributor so that the coolant flows into the cooling cavity from the inlet water distributor;

[0070] An outlet water distributor, the outlet end of the cooling cavity is connected to the flow channel of the outlet water distributor so that the coolant flowing through the cooling cavity is collected by the outlet water distributor;

[0071] Wherein, the at least two cold plates are connected between the inlet water distributor and the outlet water distributor.

[0072] According to the liquid-cooled hard disk enclosure provided by the embodiment of the present application, the cooling cavity of the cold plate is obtained by integral molding, which can form a cooling cavity within the thickness dimension of the plate material for making the cold plate, thereby reducing the thickness dimension of the cold plate and avoiding the problem that a relatively thick cold plate occupies a large height space. Therefore, within the same height space, more space can be used to accommodate the hard disk module, thereby increasing the deployment density of the hard disk module, that is, the hard disk.

[0073] In addition, based on the principle that there is a contact thermal resistance between dissimilar materials, and the contact thermal resistance will reduce the heat transfer efficiency at the contact surface of dissimilar materials, for the cooling cavity obtained by integral molding, there is no contact thermal resistance between the cooling cavity and other parts of the cold plate, so as to ensure the heat transfer efficiency from the hard disk module to the coolant, thereby improving the heat dissipation efficiency of the hard disk module.

[0101] Next, the technical solutions in the embodiments of the present application will be described with reference to the accompanying drawings in the embodiments of the present application. For the convenience of clearly describing the technical solutions in the embodiments of the present application, the first, second, etc. descriptions that appear in the embodiments of the present application are only for schematic and distinguishing the described objects, without order, and do not represent special limitations on the number of devices in the embodiments of the present application, and cannot constitute any limitation to the embodiments of the present application.

[0102] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0103] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present application is not limited by the specific implementation manners disclosed below.

[0104] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "upper", "lower", "horizontal", "bottom", "inner", "outer" (if any) is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present application. In the present application, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium.

[0105] In the present application, unless otherwise clearly specified and defined, terms such as "connected", "coupled", "fixed" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. However, indicating a direct connection means that there is no connection relationship constructed through a transition structure between the two connected main bodies, and they are only connected through the connection structure to form a whole. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0106] In the present application, descriptions such as "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first", "second" may explicitly or implicitly include at least one such feature.

[0107] With the rapid development of cloud computing, artificial intelligence (AI), and big data technologies, data centers are evolving towards high density and high energy efficiency. As the core computing power unit of a data center, the internal hard disk module of a server has a significantly increased unit power consumption and heat generation due to the continuous improvement of storage capacity and read / write frequency. Limited by problems such as the low specific heat capacity of air and uneven air flow distribution, traditional air-cooling solutions are no longer able to meet the cooling requirements in the scenario of high-density hard disk stacking. At the same time, driven by the policies of "carbon peak" and "carbon neutrality", the energy consumption efficiency requirements for data centers are becoming increasingly stringent, which promotes liquid cooling technology to become the core path to achieve energy conservation and consumption reduction. Especially with the explosive growth of AI computing power demand, the server power consumption has risen sharply and the deployment density of the computer room has continued to increase, and full liquid cooling has become an inevitable development trend.

[0108] The current server types include rack servers, blade servers, high-density servers, and standard 1U servers, etc. Among them, as a typical representative in the high-performance computing scenario, AI servers need to handle large-scale parallel computing tasks, and the thermal density of their hardware configurations (such as GPU / TPU clusters) far exceeds that of traditional servers. Therefore, it is often required that the height of a single node be strictly controlled within 1U (41.65 mm) to achieve dense deployment. This design is not only to adapt to the standardized rack space and improve the computing power density per cabinet, but also an inevitable choice to cope with the challenges of ultra-high power consumption and heat dissipation in the AI training / inference scenario.

[0109] In the server field, a liquid cooling system is configured to dissipate heat from hard drives. The liquid cooling system includes a liquid-cooled hard drive enclosure and a hard drive module. Among them, the liquid-cooled hard drive enclosure is a housing with liquid cooling function, having a plurality of accommodating cavities, and the hard drive module is inserted into the accommodating cavity, and the hard drive module contacts with the housing with liquid cooling function to take away the heat of the hard drive module through the liquid-cooled hard drive enclosure.

[0110] The embodiment of the present application provides a server. Through an integrally formed cold plate structure design, the deployment density of hard drives is increased within the limited height space inside the server, while maintaining the heat dissipation efficiency of the hard drives. Specifically, in this solution, a cooling cavity is integrally formed inside the cold plate, which can form a cooling cavity within the thickness dimension of the plate material for making the cold plate, thereby reducing the thickness dimension of the cold plate. Correspondingly, within the same height space, there will be more space for accommodating hard drives, thus increasing the deployment density of hard drives.

[0111] In other embodiments of the present application, the liquid cooling system can also be used for heat dissipation of network cards, M.2 cards, and even other modules outside the server field. The hard drive module is only used as an example of heat dissipation of the liquid cooling system, and the application examples of the liquid cooling system in the embodiments of the present application are not limited.

Figure 2A It is a schematic structural diagram of the liquid-cooled hard drive enclosure in the server provided by some embodiments of the present application; Figure 2B It is a schematic structural diagram of the hard drive in the server provided by some embodiments of the present application.

[0113] As Figures 1 to 2B shown, in the embodiment of the present application, the server 1000 includes an inlet water distributor 130, an outlet water distributor 140, and at least two cold plates 110 that are spaced apart and oppositely arranged. A cooling cavity 111 is integrally formed inside the cold plate 110, and the cooling cavity 111 is for the coolant to flow. An accommodating cavity 150 is formed between at least two cold plates 110. The accommodating cavity 150 is used for inserting a hard drive module. Among them, thermal contact means a contact that can transfer heat energy between two objects.

[0114] The inlet end of the cooling cavity 111 is connected to the flow channel of the inlet water distributor 130, so that the coolant flows into the cooling cavity 111 from the inlet water distributor 130; the outlet end of the cooling cavity 111 is connected to the flow channel of the outlet water distributor 140, so that the coolant flowing through the cooling cavity 111 is collected by the outlet water distributor 140; at least two cold plates 110 are connected between the inlet water distributor 130 and the outlet water distributor 140.

[0115] Here, the hard disk module includes a hard disk 410 and a liquid-cooled hard disk bracket. The hard disk 410 is fixed in the accommodating cavity 150 through the liquid-cooled hard disk bracket. Among them, the hard disk 410 is the core component for data storage in the server 1000.

[0116] In some embodiments, the liquid-cooled hard disk bracket includes a handle and a first sub-bracket and a second sub-bracket arranged oppositely. The handle is connected between the first sub-bracket and the second sub-bracket. In other words, the first sub-bracket and the second sub-bracket are connected to opposite ends of the handle. In this way, the liquid-cooled hard disk bracket bears the hard disk through the first sub-bracket and the second sub-bracket. The liquid-cooled hard disk bracket carrying the hard disk 410 is inserted into the accommodating cavity 150, and the handle is detachably connected to the wall of the accommodating cavity 150, so as to fix the hard disk 410 in the accommodating cavity 150.

[0117] In some examples, the liquid-cooled hard disk bracket and the wall of the accommodating cavity 150 can be detachably connected through a slide rail buckle structure. Specifically, slide rails extending along the second direction y of the cold plate are arranged on the first sub-bracket and the second sub-bracket, and a buckle for engaging with the wall of the accommodating cavity 150 is constructed at the handle; when the liquid-cooled hard disk bracket is placed in the accommodating cavity 150, the buckle on the handle is engaged with the wall of the accommodating cavity 150 to achieve detachable connection.

[0118] In some examples, the hard disk can be a standard-sized 2.5-inch hard disk or a standard-sized 3.5-inch hard disk. The embodiments of the present application do not limit the size type of the hard disk.

[0119] In some embodiments, at least two cold plates 110 are arranged at intervals along the thickness direction z of the cold plate 110. The accommodating cavity 150 extends along the second direction y of the cold plate 110, that is, two opposite openings are formed in the accommodating cavity along the second direction y of the cold plate 110. Correspondingly, the hard disk module can be inserted into the accommodating cavity 150 along the second direction y of the cold plate 110.

[0120] In some embodiments, the inlet end of the cooling cavity 111 and the outlet end of the cooling cavity 111 are located on opposite sides of the cooling cavity 111. In some examples, such as Figure 2A or Figure 3As shown, the inlet end and the outlet end can be located at opposite ends of the cooling cavity 111 along the first direction x. Correspondingly, the inlet water distributor 130 and the outlet water distributor 140 are connected to opposite ends of the cooling cavity 111 along the first direction x, which can reduce the size of the connection structure and make the structure more compact.

[0121] In some other examples, the inlet end and the outlet end can be located at opposite ends of the cooling cavity 111 along the second direction y. Correspondingly, the inlet water distributor 130 and the outlet water distributor 140 are connected to opposite ends of the cooling cavity 111 along the second direction y, which can reduce the flow path of the coolant in the cooling cavity 111, thereby improving the heat absorption efficiency. It can be understood that the external heat dissipation device can cool the high-temperature coolant to obtain low-temperature coolant, and the low-temperature coolant can be injected into the cooling cavity 111 again through the inlet water distributor 130 to take away the heat of the hard disk module.

[0122] It should be noted that when the inlet end and the outlet end can be located at opposite ends of the cooling cavity 111 along the second direction y, spaces for inserting the hard disk module should be reserved at opposite ends of the accommodating cavity 150 along the second direction y.

[0123] It can be understood that the first direction x can be understood with reference to the direction in which the inlet water distributor 130 and the outlet water distributor 140 face each other, the second direction y can be understood with reference to the direction in which the hard disk module is inserted into the accommodating cavity 150, and the thickness direction z can be understood with reference to the direction in which at least two cold plates 110 are spaced apart.

[0124] In some embodiments, the cooling cavity 111 of the cold plate 110 can be integrally formed from aluminum, such as aluminum alloy. The cold plate 110 is used for thermal contact with the hard disk module, that is, there can be heat transfer between the hard disk module and the cold plate. Specifically, when there is coolant flowing through the cooling cavity 111, the temperature of the cold plate 110 is lower than that of the hard disk module. Based on the principle of heat transfer, that is, heat transfers from an object with a higher temperature to an object with a lower temperature, the heat of the hard disk module is transferred to the cold plate 110 and is finally taken away by the coolant as it flows.

[0125] In some embodiments, the thickness dimension of the cold plate 110 is greater than or equal to 1 mm and less than or equal to 2 mm, such as 0.8 mm, 1.5 mm, 1 mm, 1.2 mm or other values, etc. The embodiments of the present application do not limit the thickness of the cold plate 110. Among them, the thickness dimension of the cold plate 110 is the dimension of the cold plate 110 along the direction in which at least two cold plates 110 are spaced apart. In Figure 2A this case, the thickness dimension of the cold plate 110 can be understood as the dimension of the cold plate 110 along the thickness direction z.

[0126] Such as Figure 2BAs shown, in some embodiments, two largest surfaces of the hard disk module are in thermal contact with the surfaces of the adjacent cold plate 110, so as to increase the contact area between the hard disk module and the cold plate and improve the heat dissipation effect. It can be understood that the hard disk 410 is a cuboid structure as a whole and has three groups of opposite surfaces. The two largest surfaces u of the hard disk module can be understood as the group of surfaces with the largest area among the three groups of opposite surfaces. It should be noted that the two largest surfaces u can be understood according to the plate surface or the top surface and the bottom surface of the hard disk in the art.

[0127] It should be noted that the first direction x, the second direction y and the thickness direction z are perpendicular to each other or approximately perpendicular to each other.

[0128] According to the server 1000 provided by the embodiments of the present application, at least two cold plates 110 are connected between the inlet water distributor 130 and the outlet water distributor 140. Thus, the inlet water distributor 130 and the outlet water distributor 140 not only serve as channels for the coolant to flow in and out, but also are used to support at least two cold plates 110, so that at least two cold plates 110 are arranged at intervals to form a receiving cavity 150. That is to say, the inlet water distributor 130, the outlet water distributor 140 and at least two cold plates 110 constitute a framework for forming the receiving cavity 150. Through the above structural arrangement, the overall architecture is simplified and miniaturization is achieved. In addition, the cooling cavity 111 of the cold plate 110 is obtained by integral molding, and the cooling cavity 111 can be formed within the thickness dimension of the plate material for making the cold plate 110, thereby reducing the thickness dimension of the cold plate 110 and avoiding the problem that the relatively thick thickness of the cold plate 110 causes a large occupation of height space. Therefore, within the same height space, there can be more space for accommodating the hard disk module, thereby improving the deployment density of the hard disk module, that is, the hard disk 410.

[0129] In addition, based on the principle that there is a contact thermal resistance between dissimilar materials, and the contact thermal resistance will reduce the heat transfer efficiency at the contact surface of dissimilar materials, for the cooling cavity 111 obtained by integral molding, there is no contact thermal resistance between the cooling cavity 111 and other parts of the cold plate 110, ensuring the heat transfer efficiency from the hard disk module to the coolant, thereby improving the heat dissipation efficiency of the hard disk module.

[0130] In some embodiments, the inlet water distributor 130 is provided with an inlet 132 for receiving the coolant externally supplied. Exemplarily, the coolant can be low-temperature water, ethylene glycol solution, etc., and the embodiments of the present application do not limit the type of the coolant.

[0131] In some embodiments, the outlet water distributor 140 is provided with an outlet 142. The high-temperature coolant that has absorbed the heat of the hard disk module flows into the flow channel of the outlet water distributor 140 from the outlet end, converges at the outlet 142, and is finally discharged to an external heat dissipation device.

[0132] Figure 3FIG. 0 is a schematic diagram of a deployment structure of a liquid-cooled hard disk enclosure in a server provided by some embodiments of the present application, showing the deployment structure when the server 1000 is deployed at the working position, as Figure 3 shown, the first direction x of the cold plate 110 is or approximately is the vertical direction. When the number of cold plates 110 is multiple, a receiving cavity 150 is formed between every two adjacent cold plates 110, and the multiple receiving cavities 150 formed by the multiple cold plates 110 are distributed in the horizontal direction. Among them, the horizontal direction and the vertical direction can be referred to Figure 3 shown for understanding.

[0133] In some embodiments, in the direction in which the hard disk module is inserted into the receiving cavity 150, the size of the cooling cavity 111 is greater than or equal to the size of the hard disk module. In the Figure 2A example, it can be understood that: the size of the cooling cavity 111 in the second direction y of the cold plate 110 is greater than or equal to the size of the hard disk module in the second direction y of the cold plate 110. In this way, the heat transfer area between the cooling cavity 111 and the hard disk module is increased, the heat absorption efficiency of the coolant is increased, and thus the heat dissipation efficiency is improved.

[0134] In the embodiments of the present application, the cooling cavity 111 can be constructed by extrusion molding or blow molding.

[0135] Figure 4 FIG. 16 is a schematic diagram of a structure of a cold plate in a server provided by some embodiments of the present application, showing the cooling cavity 111 obtained by blow molding. As Figure 4 shown, in some embodiments, when the cooling cavity 111 is obtained by blow molding, the cold plate 110 includes a first part 110a and a second part 110b, the first part 110a is connected to both sides of the second part 110b along the second direction y of the cold plate 110, and the second part 110b is used for blow molding to form the cooling cavity 111.

[0136] In some embodiments, two plates are welded and sealed along the opposite side edges to form a cavity structure. Among them, the welded part is the first part 110a of the cold plate 110, and the cavity structure is the second part 110b of the cold plate 110, so as to form a structure in which the first part 110a is connected to both sides of the second part 110b along the second direction y of the cold plate 110. Subsequently, a uniform gas pressure is applied to the cavity structure (the second part 110b) through a high-pressure gas injection device, so that the two plates undergo plastic deformation in the middle region and expand to form the cooling cavity 111.

[0137] In some examples, the two plates can be stainless steel plates or aluminum plates.

[0138] In some examples, the two plates can be plates with a thickness of 0.8 mm.

[0139] Cooling cavity 111 obtained by blow molding according to an embodiment of the present application: The double-layer sheet is blown by high-pressure gas to form the cooling cavity 111. The cooling cavity 111 is integrally formed, the height of the cooling cavity 111 is reduced, and the structure is compact, thus reducing the thickness of the cold plate 110; the height space of the server 1000 is saved, and the space for deploying hard disks in the server 1000 is increased. In addition, there is no welding joint between the double-layer sheets. After being connected to the inlet water distributor 130 and the outlet water distributor 140, the overall sealing performance is strong, and the risk of liquid leakage is low.

[0140] In some embodiments, the second part 110b has a first wall 121 and a second wall 122 that are oppositely arranged along the thickness direction z of the cold plate 110. A support column (not shown in the figure) extending along the thickness direction z of the cold plate 110 is provided between the first wall 121 and the second wall 122 to enhance the support performance of the cold plate 110.

[0141] In some embodiments, the support column can abut between the first wall 121 and the second wall 122. Specifically, the support column can be welded to the first wall 121 or the second wall 122, or the support column can be integrally formed between the first wall 121 and the second wall 122.

[0142] Through the above solution, a support column is provided between the first wall 121 and the second wall 122, so that when an external force acts on the cold plate 110, it can be dispersed to multiple support columns, thereby effectively resisting the deformation caused by the insertion and extraction and vibration of the hard disk 410, ensuring the structural strength of the cold plate 110, and guaranteeing the long-term stable operation of the server 1000.

[0143] Continue to refer to Figure 4 , in some embodiments, the second part 110b is provided with a support hole 123 for inserting a support column. Specifically, the support hole 123 penetrates the first wall 121 of the second part 110b along the thickness direction z of the cold plate 110 and at least extends to the second wall 122 of the second part 110b, and the first wall 121 and the second wall 122 are oppositely arranged. In other words, the first wall 121 and the second wall 122 of the cold plate 110 are two walls of the cooling cavity 111 along the thickness direction z.

[0144] Through the above solution, a through-type support hole 123 is provided between the first wall 121 and the second wall 122, and a support column is inserted into the support hole 123. The connection method is simple, and the yield rate of the cold plate 110 is relatively high.

[0145] In some examples, the support hole 123 penetrates the first wall 121 and the second wall 122 along the thickness direction z of the cold plate 110, which is convenient for installing the support column in the support hole 123. It should be noted that the support hole 123 and the support column should be in interference fit to prevent the support column from falling out of the support hole 123.

[0146] In some examples, the support hole 123 penetrates through the first wall 121 of the cold plate 110 and extends to the second wall 122. At this time, after the support column is inserted into the support hole 123, it abuts against the second wall 122, and the second wall 122 can assist in supporting the support column and reduce the risk of the support column falling out. In addition, the support hole 123 does not penetrate through the second wall 122, which is beneficial to ensuring the sealing performance after the cooling cavity 111 is communicated with the water inlet 132 and the water outlet 142.

[0147] In order to reduce the influence of the support column penetrating through the cooling cavity on the flow resistance of the coolant, in some embodiments, the number of support columns can be multiple, and the multiple support columns are staggered along the flow direction of the coolant in the second part 110b. Among them, the flow direction of the coolant can be the direction from the inlet water distributor 130 to the outlet water distributor 140 of the cooling cavity 111. In this way, the number of support columns arranged in the flow direction of the coolant can be reduced, thereby reducing the resistance generated by the support columns to the flow of the coolant and ensuring the flow efficiency of the coolant.

[0148] In some embodiments, the flow direction of the coolant is parallel or approximately parallel to the first direction x. Staggeredly arranging the support columns along the flow direction of the coolant can be understood as: the positions of the support holes 123 in two adjacent columns along the first direction x of the cold plate 110 are staggered. In some examples, the number of support holes 123 in one column along the second direction y of the cold plate 110 is three, denoted as the first support hole, the second support hole, and the third support hole. Then, the number of support holes 123 in the adjacent column can be two, one of which is located between the first support hole and the second support hole in the second direction y of the cold plate 110, and the other is located between the second support hole and the third support hole in the second direction y of the cold plate 110, so as to reduce the number of support columns arranged in the flow direction of the coolant and ensure the flow rate of the coolant.

[0149] Figure 5 It is another schematic structural diagram of the cold plate in the server provided by some embodiments of the present application, showing the cooling cavity 111 obtained by extrusion molding. As Figure 5As shown, in some embodiments, the cooling cavity 111 is obtained by extrusion molding. The cold plate 110 with the cooling cavity 111 obtained by extrusion molding can be manufactured through the following steps: After preheating or softening the plastic mass material, it is fed into the cavity of the extrusion equipment. Under the action of axial pressure and radial restraint force, the material is uniformly compressed and passes through a preset forming die to form the cold plate 110 with the cooling cavity 111. Through the above solution, the cold plate 110 is prepared by extrusion molding, also known as the harmonica tube process. Compared with the solution of embedding a copper tube in an aluminum plate groove and welding and fixing to obtain a cold plate, the cooling cavity 111 is integrally formed, the height of the cooling cavity 111 is reduced, and the structure is compact, thus reducing the thickness of the cold plate 110; the height space of the server 1000 is saved, and the space for deploying hard disks in the server 1000 is increased. At the same time, the extension shape of the cooling cavity 111 has a high degree of freedom, adapting to the scenario of high-density deployment of the hard disk 410. In addition, the welding process of the cold plate 110 itself is reduced, and the wall structure of the cold plate 110 is more dense, and internal air holes and cracks are not likely to appear, improving the yield rate of the cold plate 110 structural parts.

[0150] In some embodiments, partition ribs 112 extending along the flow direction of the coolant are formed inside the cold plate 110, and the partition ribs 112 penetrate through the cooling cavity 111 along the thickness direction z of the cold plate 110. In this way, the partition ribs 112, as a through-type strengthening structure, enhance the bending resistance of the cold plate 110, can effectively resist the impact during the insertion, extraction and vibration of the hard disk 410, and ensure the structural strength and heat conduction stability of the cold plate 110.

[0151] In addition, the partition ribs 112 will divide the cooling cavity 111 into multiple sub-cooling cavities extending along the flow direction of the coolant, thereby increasing the contact area between the coolant and the inner wall of the sub-cooling cavity, thus increasing the heat transfer area between the cold plate 110 and the coolant, and effectively improving the heat dissipation efficiency of the hard disk module. In some embodiments, there are 1, 2, 3 or other numbers of partition ribs in the cold plate 110, and the embodiments of the present application limit the number of the partition ribs 112. In addition, since the partition ribs 112 extend inside the cold plate 110 along the flow direction of the coolant, the flow of the coolant is not affected, thus ensuring the flow rate of the coolant.

[0152] In Figure 2A the illustrated example, the flow direction of the coolant is or approximately is the first direction x. In other words, the partition ribs 112 can extend inside the cold plate 110 along the first direction x.

[0153] In some examples, there is 1 partition rib 112 in the cold plate 110, and the partition rib 112 extends along the first direction x of the cold plate 110 to divide the cooling cavity 111 into 2 sub-cooling cavities arranged along the second direction y, and the 2 sub-cooling cavities extend along the first direction x.

[0154] In some examples, 5 partition ribs 112 are provided in the cooling cavity 111 (see Figure 5 ). The 5 partition ribs 112 are arranged at intervals along the first direction x of the cold plate 110, and the partition ribs 112 extend along the first direction x of the cold plate 110 to divide the cooling cavity 111 into 6 sub-cooling cavities arranged along the second direction y, and the 6 sub-cooling cavities extend along the first direction x.

[0155] In some embodiments, in the flowing direction of the coolant, the ratio of the flow-through cross-sectional area of the cooling cavity 111 to the cross-sectional area of the cold plate 110 is 3:10 to 3:5 (including the values at both ends). In this way, the occupied space of the cooling cavity 111 is increased, the flow resistance of the coolant is reduced, the flow-through rate of the coolant is increased, and the heat dissipation efficiency of the hard disk module is effectively improved.

[0156] It should be noted that if the ratio of the flow-through cross-sectional area of the cooling cavity 111 to the cross-sectional area of the cold plate 110 is less than 3:10, then the flow-through cross-sectional area of the cooling cavity 111 is relatively small, and the heat dissipation effect on the hard disk module may not be guaranteed. If the ratio of the flow-through cross-sectional area of the cooling cavity 111 to the cross-sectional area of the cold plate 110 is greater than 3:5, then the wall thickness of the cold plate 110 is relatively small, and the structural strength of the cold plate 110 may not be guaranteed. Therefore, the ratio of the flow-through cross-sectional area of the cooling cavity 111 to the cross-sectional area of the cold plate 110 is set to 3:10 to 3:5, for example, 3:5, 3:5.5, 3:6, 3:10 or other values, and the embodiments of the present application do not make specific limitations on this ratio.

[0157] In some embodiments, the flow resistance of the cold plate 110 can be reduced to 2000 Pa, increasing the heat absorption efficiency of the coolant, thereby improving the heat dissipation efficiency.

[0158] As Figure 2A shown, in some embodiments, in order to adapt to cold plate forming devices with different parameters, the cold plate 110 may include a main body section 101 and a support portion 102. The main body section 101 is used to form the cooling cavity 111. The support portion 102 supports the hard disk module. Correspondingly, the dimension of the main body section 101 along the second direction y is determined according to the parameters of the forming device, and the present application does not limit the dimension of the main body section 101.

[0159] In some embodiments, the dimension of the support portion 102 along the second direction y can be designed corresponding to the dimension of the area with relatively small heat dissipation requirements in the hard disk module, and the present application does not limit the dimension of the support portion 102. In this way, cold plate 110 with an integrated cooling cavity 111 provided by the embodiments of the present application can be applied to forming devices with different parameters, improving the practicability of the server 1000 provided by the embodiments of the present application.

[0160] To change the layout direction of the hard disk module, as Figure 2AAs shown, in some embodiments, the server 1000 further includes a middle partition 160, which is inserted between adjacent cold plates 110 to form at least two accommodation cavities 150 distributed along the first direction x of the cold plate 110 between the adjacent cold plates 110. In this way, a plurality of accommodation cavities 150 with different sizes are obtained between the adjacent cold plates 110, and hard disk modules with different sizes can be inserted, thereby improving the adaptability of the accommodation cavities 150.

[0161] Here, the number of the middle partitions 160 between the adjacent cold plates 110 can be comprehensively determined according to parameters such as the size of the hard disk module, the internal space of the server 1000, and user requirements. The embodiments of the present application do not limit the number of the middle partitions 160 between two adjacent layers of cold plates.

[0162] In some embodiments, if the number of the middle partitions 160 between the adjacent cold plates 110 is 1, then 1 middle partition 160 can be inserted between the adjacent cold plates 110 along the thickness direction z of the cold plate 110 to separate at least two accommodation cavities 150 between the adjacent cold plates 110. Thus, each accommodation cavity 150 accommodates one hard disk module, and then, two hard disk modules can be accommodated between the adjacent cold plates 110.

[0163] In some examples, if 1 middle partition 160 is inserted at the middle position of the cold plate 110 along the first direction x, the spatial dimensions of the two separated accommodation cavities 150 are the same.

[0164] In other examples, if 1 middle partition 160 is inserted at a non-middle position of the cold plate 110 along the first direction x, the spatial dimensions of the two separated accommodation cavities 150 are different and can be used to insert hard disk modules with different sizes.

[0165] In other some embodiments, if the number of the middle partitions 160 between the adjacent cold plates 110 is n, then n middle partitions 160 can be inserted between the adjacent cold plates 110 at intervals along the thickness direction z of the cold plate 110 to separate n + 1 accommodation cavities 150 between the adjacent cold plates 110. Thus, each accommodation cavity 150 accommodates one hard disk module, and then, n + 1 hard disk modules can be accommodated between the adjacent cold plates 110, where n is an integer greater than or equal to 2.

[0166] In some examples, n middle partitions 160 are uniformly inserted between the adjacent cold plates 110 along the first direction x of the cold plate 110 to divide n + 1 accommodation cavities 150 with the same size between the adjacent cold plates 110 for inserting hard disk modules with the same size.

[0167] Continue to refer to Figure 2A, which shows the layout of a liquid-cooled hard disk frame taking a 1U height space as an example. Among them, n is 3, and the three middle partitions 160 are evenly inserted between adjacent cold plates 110 along the first direction x of the cold plate 110, so as to divide 4 accommodation cavities 150 with the same size between adjacent cold plates 110 for inserting hard disk modules with the same size. Figure 2A The shown server 1000 includes three cold plates 110. Then, 8 accommodation cavities 150 can be separated between the three cold plates 110 to accommodate 8 hard disk modules. In some examples, among the 8 hard disk modules, the hard disks 410 in each hard disk module are all 2.5-inch standard hard disks. It can be concluded that under the limitation of the 1U height space, two rows of hard disks 410 are successfully deployed, with 4 2.5-inch standard hard disks in each row, achieving the same hard disk configuration as air cooling, and meeting the heat dissipation requirements of the hard disks, without reducing the deployment density due to the reduction of hard disk heat dissipation caused by adopting the liquid cooling scheme for heat dissipation.

[0168] It can be understood that when the space of the server 1000 permits, the accommodation cavities 150 of the liquid-cooled hard disk frame 100 can also be configured to insert hard disk modules with a size of 3.5 inches or other forms of hard disk modules, which has high practicability.

[0169] In other examples, n middle partitions 160 are unevenly inserted between adjacent cold plates 110 along the first direction x of the cold plate 110, so as to divide n + 1 accommodation cavities 150 with different sizes between adjacent cold plates 110 for inserting hard disk modules with different sizes.

[0170] Figure 6 is another deployment structure schematic diagram of the liquid-cooled hard disk frame in the server provided by some embodiments of the present application, which shows another deployment structure when the server 1000 is deployed at the working position, as Figure 6 shown, the first direction x of the cold plate 110 is or approximately horizontal. When the number of cold plates 110 is 3, the three cold plates 110 are arranged at intervals in the vertical direction. The number of middle partitions 160 between adjacent cold plates 110 is 2, and 3 accommodation cavities 150 are separated by 2 middle partitions 160 between adjacent two cold plates 110, and the three accommodation cavities 150 are distributed in the horizontal direction. Among them, the horizontal direction and the vertical direction can be understood with reference to Figure 6 shown. At this time, the hard disk module is horizontally inserted into the accommodation cavity 150 along the second direction y of the cold plate 110. Horizontally inserting means that when the hard disk module is at the working position, the two largest surfaces of the hard disk module are relatively arranged in the vertical direction.

[0171] Through the above solution, at least two cold plates 110 are arranged at intervals in the vertical direction, and the hard disk module is inserted horizontally into the accommodating cavity 150. Combining with the above-described embodiment in which the hard disk module is inserted vertically into the accommodating cavity 150, the hard disk module can be inserted horizontally or vertically. And when the number of cold plates 110 is three or more, the hard disk module is located between adjacent cold plates 110. Since the cooling cavity 111 is obtained by integral molding, both opposite sides of the cold plate 110 in the thickness direction z can contact the hard disk module, thereby absorbing the heat on the hard disk module and transferring the heat to the coolant. This design forms a "sandwich" heat dissipation structure, that is, each hard disk module is simultaneously cooled by two cold plates 110 in contact with it, effectively improving the heat dissipation capacity. At the same time, on the premise of ensuring efficient heat dissipation, the requirement of high-density deployment of hard disks under the 1U chassis height of the server 1000 is met, achieving a double optimization of heat dissipation performance and space utilization rate.

[0172] Figure 7 is a schematic cross-sectional structure diagram obtained by cutting the server provided in some embodiments of the present application along the first direction; Figure 8 is Figure 7 an enlarged structural schematic diagram of the part A shown; Figure 9 is a structural schematic diagram of the middle partition board in the server provided in some embodiments of the present application; Figure 10 is a structural schematic diagram of the cold plate in the server provided in some embodiments of the present application. As Figures 7 to 10 shown, in some embodiments, the middle partition board 160 forms a first abutting portion 161 and a second abutting portion 162 in the direction (which can be understood as the second direction y) in which the hard disk module is inserted into the accommodating cavity 150. The cold plate 110 has a first side wall 1151 and a second side wall 1161 oppositely arranged along its own second direction y. Among them, the first abutting portion 161 abuts against the first side wall 1151, and the second abutting portion 162 abuts against the second side wall 1161. Thereby, the middle partition board 160 is inserted between adjacent cold plates 110.

[0173] Through the above solution, by using the first abutting portion 161 and the second abutting portion 162 formed at intervals along the second direction y of the cold plate 110 to abut against the first side wall 1151 and the second side wall 1161 of the cold plate 110, the stability of the middle partition board 160 inserted between adjacent cold plates is realized; there is no need to add additional fixing parts, the structural design is simplified, and the manufacturing cost is reduced.

[0174] In some embodiments, the middle partition 160 has a first wall and a second wall disposed opposite to each other in the second direction y of the cold plate 110, and the first abutting portion 161 can be formed by folding a part of the surface of the first wall outward. Specifically, after a part of the surface of the first wall extends outward, it is folded along the thickness direction z of the cold plate 110 to form the first abutting portion 161. The second abutting portion 162 can be formed by folding a part of the surface of the second wall outward. Specifically, after a part of the surface of the second wall extends outward, it is folded along the thickness direction z of the cold plate 110 to form the second abutting portion 162.

[0175] It can be understood that the first abutting portion 161 and the second abutting portion 162 can be located on the same side of the middle partition 160 along the thickness direction z of the cold plate 110, so as to enable the first abutting portion 161 and the second abutting portion 162 to abut against the first side wall 1151 and the second side wall 1161 of one of the adjacent cold plates 110; or, the first abutting portion 161 and the second abutting portion 162 are located on opposite sides of the middle partition 160 along the thickness direction z, so as to enable the first abutting portion 161 to abut against the first side wall 1151 of one of the adjacent cold plates 110, and the second abutting portion 162 to abut against the second side wall 1161 of the other of the adjacent cold plates 110 respectively, as long as the middle partition 160 can be stably abutted between the adjacent cold plates 110.

[0176] Please refer to Figure 9 , in some other embodiments, both the first abutting portion 161 and the second abutting portion 162 are configured to be formed by protruding outward from a side wall of the middle partition 160 along the thickness direction z of the cold plate 110.

[0177] Wherein, the middle partition 160 has a third wall and a fourth wall disposed opposite to each other along the thickness direction z of the cold plate 110, and the first abutting portion 161 and the second abutting portion 162 are configured to be formed by protruding outward from part of the surfaces separated by the third wall.

[0178] Please refer to Figure 9 , in some embodiments, two sets of abutting portions are formed on the middle partition 160, and each set of abutting portions includes a first abutting portion 161 and a second abutting portion 162. The first set of abutting portions is used to abut against one of the adjacent cold plates 110, and the second set of abutting portions is used to abut against the other of the adjacent cold plates 110. Wherein, the first set of abutting portions is formed by protruding outward from part of the surfaces separated by the third wall. The second set of abutting portions is formed by protruding outward from part of the surfaces separated by the fourth wall. As Figure 9 shown, the first abutting portion 161 and the second abutting portion 162 located in the upper part can be understood as the first set of abutting portions, and the ones located Figure 9The first abutting portion 161 and the second abutting portion 162 at the lower part are understood as the second group of abutting portions. At this time, when the middle partition plate 160 is inserted between adjacent cold plates 110, the first group of abutting portions at the upper part are used to abut against the cold plate 110 on one side of the third side wall; the second group of abutting portions at the lower part are used to abut against the cold plate 110 on one side of the fourth side wall.

[0179] It can be understood that the distance d1 between the first abutting portion 161 and the second abutting portion 162 in the second direction y of the cold plate 110 is equal to the width dimension of the cold plate 110, so that the first abutting portion 161 and the second abutting portion 162 can abut against the cold plate 110.

[0180] As Figure 10 shown, in some embodiments, the cold plate 110 has a first surface 110c and a second surface 110d which are oppositely arranged along its own second direction y. In some examples, the first surface 110c serves as the first side wall 1151, and the second surface 110d serves as the second side wall 1161.

[0181] In other embodiments, the first surface 110c is recessed inward to form a first recess 115, and the bottom wall of the first recess 115 serves as the first side wall 1151. The second surface 110d is recessed inward to form a second recess 116, and the bottom wall of the second recess 116 serves as the second side wall 1161. In this way, since the first side wall 1151 is recessed in the first surface 110c and the second side wall 1161 is recessed in the second surface 110d, it is convenient for the first abutting portion 161 to abut against the first side wall 1151 or the second abutting portion 162 to abut against the second side wall 1161 for positioning. The first abutting portion 161 and the second abutting portion 162 are also not easy to slide along the first direction of the cold plate 110, thereby improving the stability of the middle partition plate 160 inserted between adjacent cold plates 110.

[0182] Please continue to refer to Figure 2A As Figure 2A shown, in some embodiments, the inlet water distributor 130 can have a multi-channel flow splitting structure inside, which is used to receive the coolant from the water inlet 132 and then distribute the coolant to the cooling cavities 111 of multiple cold plates 110. The number of flow channels of the inlet water distributor 130 is the same as the number of cold plates 110.

[0183] In some examples, the number of cold plates 110 is three, which are respectively denoted as the first cold plate, the second cold plate, and the third cold plate. The first cold plate, the second cold plate, and the third cold plate are spaced apart and oppositely arranged. The cooling cavities of the first cold plate, the second cold plate, and the third cold plate are respectively denoted as the first cooling cavity, the second cooling cavity, and the third cooling cavity. The same ends of the first cooling cavity, the second cooling cavity, and the third cooling cavity communicate with different flow channels of the inlet water distributor 130. Correspondingly, in the case where heat dissipation for the hard disk module is required, the inlet water distributor 130 is used to distribute the coolant to the first cooling cavity, the second cooling cavity, and the third cooling cavity through different flow channels.

[0184] Here, a flow-accumulating cavity is designed inside the outlet water distributor 140 for collecting the coolant in each cold plate 110 to the water outlet 142.

[0185] In some examples, the number of cold plates 110 is three, which are respectively denoted as the first cold plate, the second cold plate, and the third cold plate. The first cold plate, the second cold plate, and the third cold plate are spaced apart and oppositely arranged. The cooling cavities of the first cold plate, the second cold plate, and the third cold plate are respectively denoted as the first cooling cavity, the second cooling cavity, and the third cooling cavity. The other ends of the first cooling cavity, the second cooling cavity, and the third cooling cavity communicate with different flow channels of the outlet water distributor 140. Correspondingly, in the case of heat dissipation for the hard disk module, the outlet water distributor 140 is used to collect the coolant in the first cooling cavity, the second cooling cavity, and the third cooling cavity to the water outlet 142.

[0186] In this way, a flow path of the coolant is formed (as shown by the arrow a in Figure 3 or Figure 6 ): The coolant enters the inlet water distributor 130 from the water inlet 132. The inlet water distributor 130 diverts the coolant into the cooling cavities of each cold plate 110. The coolant flows along the cooling cavity 111 to absorb the heat from the hard disk module. The high-temperature coolant that has absorbed the heat is collected by the outlet water distributor 140 to the water outlet 142 and finally discharged to the external radiator.

[0187] Among them, the external radiator can be a liquid-liquid heat exchanger, an air-cooled radiator, etc., to cool down the high-temperature coolant to obtain the coolant that can be supplied to the cooling cavity 111 again.

[0188] Through the above solution, an inlet water distributor 130 and an outlet water distributor 140 are introduced. The inlet water distributor 130 evenly distributes the coolant into multiple cold plates 110, making the coolant flow rate in each cold plate 110 consistent, avoiding local overheating, and being beneficial to ensuring the performance of the server 1000. The current collection design of the outlet water distributor 140 can reduce the pressure drop and maintain the efficient operation of the liquid cooling system of the server 1000. All in all, through the connection design of the inlet water distributor 130 and the outlet water distributor 140, the efficient distribution and collection of the coolant are achieved. Combined with the integrated structure of the cooling cavity 111, a stable and reliable closed-loop liquid cooling system is formed.

[0189] In some embodiments, the cold plate 110 and the inlet water distributor 130 are connected by a quick-connect plug to realize the docking and connection of the flow channels in the cooling cavity 111 and the inlet water distributor 130.

[0190] In other embodiments, the cold plate 110 and the inlet water distributor 130 are connected by a crimping joint to realize the docking and connection of the flow channels in the cooling cavity 111 and the inlet water distributor 130.

[0191] In some embodiments, the technical solution for connecting the cold plate 110 and the outlet water distributor 140 may refer to the implementation manner of connecting the cold plate 110 and the inlet water distributor 130, which will not be elaborated here.

[0192] Figure 11 For Figure 7 the enlarged structural schematic diagram at position B shown in the figure. As Figure 2A , Figure 7 and Figure 11 shown, in some embodiments, the inlet end of the cold plate 110 is inserted into the inlet water distributor 130 so that the flow channels in the cooling cavity 111 and the inlet water distributor 130 are docked and connected. The outlet end of the cold plate 110 is inserted into the outlet water distributor 140 so that the flow channels in the cooling cavity 111 and the outlet water distributor 140 are docked and connected.

[0193] In order to make the size of the cooling cavity 111 along the second direction y of the cold plate 110 as large as possible and reduce the redundant space on both sides of the cold plate 110 along the second direction y, in some embodiments, the surface of the inlet water distributor 130 for communicating with the inlet end is recessed inward to form an interface portion, and the inlet end of the cold plate 110 is directly embedded in the interface portion to realize the docking and connection between the flow channels of the cooling cavity 111 and the inlet water distributor 130. In this way, no structural modification is required for the cold plate 110, the size of the cooling cavity 111 along the second direction y of the cold plate 110 is increased, and further the cross-sectional area of the cooling cavity 111 is increased, which is beneficial to reducing the flow resistance of the coolant in the cooling cavity 111.

[0194] It should be noted that an interference fit can be provided between the cold plate 110 and the interface portion to ensure the stable connection between the cold plate 110 and the inlet water distributor 130, as well as the sealing performance of the communication between the cooling cavity 111 and the flow channel of the inlet water distributor 130.

[0195] In some embodiments, the technical solution of the plug connection between the cold plate 110 and the outlet water distributor 140 may refer to the implementation manner of the plug connection between the cold plate 110 and the inlet water distributor 130, which will not be elaborated herein.

[0196] Please continue to refer to Figure 11 , to make the structure more compact, a part of the surface at the inlet end of the cold plate 110 extends outward to form a first plugging portion 113, and the surface of the inlet water distributor 130 for communicating with the inlet end is recessed inward to form a first insertion portion 131. The first plugging portion 113 is located within the first insertion portion 131 to achieve the butt joint and communication between the cooling cavity 111 and the flow channel of the inlet water distributor 130. Among them, the contour dimensions of the first plugging portion 113 and the first insertion portion 131 match.

[0197] In some embodiments, when the first plugging portion 113 and the first insertion portion 131 are aligned and plugged, the flow channels of the cooling cavity 111 and the inlet water distributor 130 are aligned and connected.

[0198] In some embodiments, the outward extension of the inlet end of the cold plate 110 to form the first plugging portion 113 can be understood as follows. Among them, the width dimension refers to the dimension of the indicated structure along the second direction y, and the thickness dimension refers to the dimension of the indicated structure along the thickness direction z:

[0199] In some examples, the width dimension of the first plugging portion 113 is equal to the width dimension of other parts of the cold plate 110, and the thickness dimension of the first plugging portion 113 is smaller than the thickness dimension of other parts of the cold plate 110. Reducing the thickness of the first plugging portion 113 is beneficial to improving the space utilization rate and reducing the structural size of the liquid-cooled hard disk frame.

[0200] In some examples, the width dimension of the first plugging portion 113 is smaller than the width dimension of other parts of the cold plate 110, and the thickness dimension of the first plugging portion 113 is equal to the thickness dimension of other parts of the cold plate 110, which is beneficial to saving lateral space and maintaining the strength of the cold plate 110.

[0201] In some examples, the width dimension of the first plugging portion 113 is smaller than the width dimension of other parts of the cold plate 110, and the thickness dimension of the first plugging portion 113 is smaller than the thickness dimension of other parts of the cold plate 110, which can make the structure more compact.

[0202] In some embodiments, the matching of the contour dimensions of the first plug-in portion 113 and the first insertion portion 131 can be achieved in the following manner: the dimension of the first plug-in portion 113 along the first direction x is less than, greater than, or equal to the dimension of the first insertion portion 131 along the first direction x; the dimension of the first plug-in portion 113 along the second direction y matches the dimension of the first insertion portion 131 along the second direction y, and the dimension of the first plug-in portion 113 along the second direction y matches the dimension of the first insertion portion 131 along the second direction y.

[0203] In some examples, the dimension of the first plug-in portion 113 along the second direction y and the dimension of the first insertion portion 131 along the second direction y are in an interference fit to ensure plug-in stability and sealing.

[0204] In some examples, the dimension of the first plug-in portion 113 along the first direction x is smaller than the dimension of the first insertion portion 131 along the first direction x, and the first plug-in portion 113 is fully inserted into the first insertion portion 131, thereby avoiding a gap between the first plug-in portion 113 and the first insertion portion 131 in the second direction y of the cold plate 110 or in the thickness direction of the cold plate 110, thereby ensuring sealing.

[0205] In some examples, the dimension of the first plug-in portion 113 along the first direction x is equal to the dimension of the first insertion portion 131 along the first direction x, and the first plug-in portion 113 is just inserted into the first insertion portion 131, thereby avoiding dimension redundancy of the first plug-in portion 113 or the first insertion portion 131 in the first direction x of the cold plate 110, reducing the length dimension of the liquid-cooled hard disk frame, and making the structure of the server 1000 more compact.

[0206] In some examples, the dimension of the first plugging portion 113 along the first direction x is greater than the dimension of the first inserting portion 131 along the first direction x, which can ensure that the first plugging portion 113 is tightly inserted into the first inserting portion 131 and improve the structural connection stability.

[0207] Through the above solution, the first plug-in portion 113 and the first insertion portion 131 are aligned and plugged together to achieve convenient installation between the cold plate 110 and the inlet water distributor 130, while achieving efficient communication between the cooling cavity 111 and the flow channel of the inlet water distributor 130.

[0208] In some embodiments, a portion of the surface of the outlet end of the cold plate 110 extends outward to form a second plug-in portion, and the surface of the outlet water distributor 140 for communicating with the outlet end is recessed inward to form a second insertion portion, and the second plug-in portion is located in the second insertion portion to achieve docking communication between the cooling cavity 111 and the flow channel of the outlet water distributor 140. The second plug-in portion and the second insertion portion have matching outline dimensions.

[0209] Among them, the technical solution of the second plugging part can refer to the implementation manner of the foregoing first plugging part, and the technical solution of the second inserting part can refer to the implementation manner of the foregoing first inserting part, which will not be elaborated herein.

[0210] In order to ensure the sealing performance after the first plugging part 113 is plugged with the first inserting part 131, in some embodiments, when the cold plate 110 is plugged with the inlet water distributor 130, the cold plate 110 and the inlet water distributor 130 are hermetically connected through a sealing member (not shown in the figure) at the plugging position. Thus, there is no need for the first plugging part 113 and the first inserting part 131 to achieve hermetic connection through interference fit, reducing the assembly difficulty and ensuring the sealing performance of the connection between the cold plate 110 and the inlet water distributor 130.

[0211] In some embodiments, the sealing member is configured as solder. Correspondingly, the cold plate 110 and the inlet water distributor 130 are welded through solder at the plugging position, and the solder fills the plugging gap between the first plugging part 113 and the first inserting part 131. Among them, the plugging gap is the gap between the first plugging part 113 and the first inserting part 131 that does not correspond to the first direction x of the cold plate 110.

[0212] Among them, the hermetic connection through solder can be achieved in the following manner: the solder is coated on the two surfaces of the first plugging part 113 along the thickness direction of the cold plate 110, and the two surfaces of the first plugging part 113 along the second direction y. The first plugging part 113 is welded to the inner wall of the first inserting part 131 through the solder on these four surfaces.

[0213] In some examples, the solder can be a brazing material.

[0214] In some other embodiments, the sealing member is configured as an adhesive. Correspondingly, the cold plate 110 and the inlet water distributor 130 are hermetically connected through the adhesive at the plugging position, and the adhesive fills the plugging gap between the first plugging part 113 and the first inserting part 131.

[0215] Among them, the hermetic connection through the adhesive can be achieved in the following manner: the adhesive is coated on the two surfaces of the first plugging part 113 along the thickness direction of the cold plate 110, and the two surfaces of the first plugging part 113 along the second direction y. The first plugging part 113 is adhesively sealed to the inner wall of the first inserting part 131 through the adhesive on these four surfaces.

[0216] In some examples, the adhesive can be a solid glue, or a liquid glue, etc. The embodiments of the present application do not limit the type of the adhesive.

[0217] To ensure the sealing performance after the second plugging part is plugged into the second insertion part, in some embodiments, when the cold plate 110 is plugged into the outlet water distributor 140, the cold plate 110 and the outlet water distributor 140 are sealingly connected through a sealing member at the plugging position. Thus, there is no need to achieve a sealing connection through the interference fit between the second plugging part and the second insertion part, reducing the assembly difficulty and ensuring the sealing performance of the connection between the cold plate 110 and the outlet water distributor 140.

[0218] Among them, the technical solution of the cold plate 110 and the outlet water distributor 140 being sealingly connected through a sealing member at the plugging position can refer to the aforementioned implementation manner of the cold plate 110 and the inlet water distributor 130 being sealingly connected through a sealing member at the plugging position, and will not be elaborated here.

[0219] In some embodiments, after the water inlet 132 is connected to the inlet water distributor 130, the water inlet 132 is connected to the water inlet pipe, so that the coolant flows into the inlet water distributor 130 from the water inlet 132.

[0220] Among them, the water inlet 132 can be communicated with the water inlet pipe through a flare fitting. It should be noted that connecting the water inlet 132 and the water inlet pipe through a flare fitting is only an example, and the embodiments of the present application do not limit the connection manner between the water inlet 132 and the water inlet pipe.

[0221] In some embodiments, when the cold plate 110 is in the working position and its first direction x is or approximately horizontal, the water inlet 132 is connected to a relatively upper position of the inlet water distributor 130. Based on the principle that water flows to lower places, this design of the position of the water inlet 132 is beneficial for the coolant to flow into each cooling cavity 111 with the assistance of gravity, without the need to add a pressurizing device to introduce the coolant into each cooling cavity 111.

[0222] In some embodiments, after the water outlet 142 is connected to the outlet water distributor 140, the water outlet 142 is connected to the water outlet pipe, so that the coolant is collected to an external radiator through the water outlet 142.

[0223] Among them, the water outlet 142 can be communicated with the water outlet pipe through a flare fitting. It should be noted that connecting the water outlet 142 and the water outlet pipe through a flare fitting is only an example, and the embodiments of the present application do not limit the connection manner between the water outlet 142 and the water outlet pipe.

[0224] In some embodiments, when the cold plate 110 is in the working position and its first direction x is or approximately horizontal, the water outlet 142 is connected to a relatively lower position of the inlet water distributor 130. Based on the principle that water flows to lower places, this design of the position of the water outlet 142 is beneficial for the coolant to flow to the water outlet 142 with the assistance of gravity, without the need to add a pressurizing device to lead the coolant to the water outlet 142.

[0225] It can be understood that the water inlet 132 can be directly provided on the inlet water distributor 130, and the water inlet 132 is communicated with the water inlet pipe. The water outlet 142 can be directly provided on the outlet water distributor 140, and the water outlet 142 is communicated with the water outlet pipe.

[0226] In order to enhance the heat conduction efficiency between the hard disk module and the cold plate 110, in some embodiments, the server 1000 further includes an elastic member disposed between the hard disk module and the cold plate 110 to achieve elastic contact between the hard disk 410 and the cold plate 110, thereby avoiding the problem of a small contact area caused by hard contact between the hard disk 410 and the cold plate 110, improving the contact area between the hard disk 410 and the cold plate 110, thereby increasing the heat transfer area and increasing the heat dissipation efficiency of the hard disk.

[0227] Among them, elastic contact can also be called soft contact, which is different from hard contact.

[0228] In some embodiments, the elastic member can be configured as an elastic pad, and the elastic pad is attached to the area of the cold plate 110 corresponding to the surface of the hard disk 410. Thus, when the hard disk module is inserted into the accommodating cavity 150, elastic contact between the hard disk module and the cold plate 110 is achieved by using the elastic deformation of the elastic pad.

[0229] In some embodiments, the elastic member can be an elastic insert strip, and the elastic insert strip is softly wrapped around the heat dissipation teeth of the hard disk 410. Thus, when the hard disk module is inserted into the accommodating cavity 150, elastic contact between the hard disk module and the cold plate 110 is achieved by using the elastic deformation of the elastic insert strip.

[0230] It can be understood that the elastic member has a heat transfer function, that is, the thermal conductivity coefficient of the elastic member cannot have a negative impact on the heat transfer of the hard disk module to the coolant.

[0231] Figure 12 This is a schematic structural diagram of the hard disk module and the liquid-cooled hard disk frame in the server provided by the embodiment of the present application. As Figure 2B and Figure 12 shown, in some embodiments, the hard disk module includes a hard disk 410 and a liquid-cooled hard disk bracket 300. The liquid-cooled hard disk bracket 300 has a loading cavity 321, the hard disk 410 is loaded in the loading cavity 321, and the liquid-cooled hard disk bracket 300 is inserted into the accommodating cavity 150; the elastic member is disposed between the hard disk 410 and the cold plate 110. In this way, the elastic member is disposed between the hard disk and the cold plate 110 to achieve elastic contact between the hard disk and the cold plate 110, improving the contact area between the hard disk and the cold plate 110, thereby increasing the heat transfer area and increasing the heat dissipation efficiency of the hard disk 410.

[0232] Figure 13 This is a schematic structural diagram of the bracket in the server 1000 provided by some embodiments of the present application. As Figure 13As shown, in some embodiments, the server 1000 further includes a bracket 170. The bracket 170 is disposed between the hard disk module and the cold plate 110. An elastic member is provided on one side of the bracket 170 facing the hard disk 410 and / or facing the cold plate 110, that is, the elastic member is located between the bracket 170 and the hard disk module, or the elastic member is located between the bracket 170 and the cold plate 110, or the elastic member is located between the bracket 170 and the hard disk module and between the bracket 170 and the cold plate 110. In this way, the bracket 170 and the elastic member are sandwiched between the cold plate 110 and the hard disk, and the elastic contact between the cold plate 110 and the hard disk is achieved by using the elastic action of the elastic member. In addition, when the elastic member loses its elasticity and needs to be replaced, only the bracket 170 needs to be replaced, which reduces the impact on other structures and is beneficial to later maintenance.

[0233] In some embodiments, the bracket 170 is an overall plate structure, which can reduce the height occupation in the 1U height space inside the server 1000 and expand the space for accommodating the hard disk module as much as possible.

[0234] In some embodiments, the elastic member can be attached to one side surface of the bracket 170, and the application does not limit the connection method of the elastic member provided on the bracket 170.

[0235] In some examples, the number of elastic members can be 1, and its contour size matches the largest surface of the hard disk 410 to achieve the elastic contact area with the largest surface of the hard disk 410.

[0236] In some examples, the number of elastic members can be multiple, and the multiple elastic members are dispersedly distributed on the bracket 170, which is beneficial to maintaining the structural strength of the bracket 170 and enhancing the structural stability.

[0237] Figure 14 Yes Figure 13 It is a schematic cross-sectional structure diagram when the shown bracket is connected to the cold plate; Figure 15 Is Figure 14 It is a schematic structural diagram when the hard disk module is inserted into the structure shown. As Figure 14 And Figure 15 As shown, in some examples, the bracket 170 is connected to the surface of the cold plate 110 for dissipating heat from the hard disk module, that is, the surface of the cold plate 110 along its own thickness direction z. The elastic member is located on the side of the bracket 170 facing the accommodation cavity. At this time, when the hard disk module is inserted into the accommodation cavity 150, the elastic member is in elastic contact with the hard disk 410, thereby realizing the elastic contact between the hard disk 410 and the cold plate 110. In addition, the bracket 170 is directly disposed on the cold plate 110, which can support the hard disk module to directly insert into the accommodation cavity 150 and directly perform water-cooling heat dissipation.

[0238] In some embodiments, the bracket 170 is adhesively bonded to the cold plate 110. Specifically, the adhesive is coated on the area of the bracket 170 that does not correspond to the elastic member, and the bracket 170 is adhesively bonded to the cold plate 110 through the adhesive. When the adhesive is configured as a tearable adhesive tape, it is convenient to disassemble the bracket 170 from the cold plate 110.

[0239] In some embodiments, the bracket 170 is welded to the cold plate 110. Specifically, the solder is coated on the area of the bracket 170 that does not correspond to the elastic member, and then the bracket 170 is welded to the cold plate 110, providing a firm connection.

[0240] Figure 16 is a schematic structural diagram of the bracket connected to the liquid-cooled hard disk bracket; Figure 17 is Figure 16 an exploded structural diagram of the shown bracket when connected to the liquid-cooled hard disk bracket; Figure 18 is Figure 16 a cross-sectional structural diagram of the shown bracket when connected to the liquid-cooled hard disk bracket;

[0241] Figure 19 is Figure 16 a cross-sectional structural diagram of the shown structure when loading the hard disk.

[0242] As Figures 16 to 19 shown, in some examples, the bracket 170 is connected to the inner wall of the liquid-cooled hard disk bracket 300, and the elastic member protrudes from the liquid-cooled hard disk bracket 300. At this time, when the hard disk module is inserted into the accommodation cavity 150, the elastic member is in elastic contact with the cold plate 110, thereby realizing elastic contact between the hard disk 410 and the cold plate 110.

[0243] Here, the liquid-cooled hard disk bracket 300 includes a first plate surface 300a (which can be understood as a plate surface), and the first plate surface 300a is located in the direction of the cold plate thickness direction z of the liquid-cooled hard disk bracket 300. In other words, the extended plane of the first plate surface 300a is parallel or approximately parallel to the extended plane of the cold plate 110. The bracket 170 is connected to the inner wall of the first plate surface 300a.

[0244] In order to enable the elastic member to protrude from the liquid-cooled hard disk bracket 300 and contact the cold plate 110, a plurality of through holes 322 are formed on the first plate surface 300a, and the elastic member protrudes from the liquid-cooled hard disk bracket 300 through the through holes 322, thereby being in elastic contact with the cold plate 110.

[0245] Here, the projection size of the through hole 322 on the first plate surface 300a is the same as that of the elastic member, so that the elastic member can protrude from the through hole 322.

[0246] In some examples, the number of elastic members is 1, and the number of through holes 322 is 1.

[0247] In some examples, the number of elastic members is n, and the number of through holes 322 is also n, where n is an integer greater than or equal to 2.

[0248] In some embodiments, the technical solution of the bracket 170 connected to the inner wall of the first plate surface 300a may refer to the implementation manner of the bracket 170 connected to the cold plate 110 described above, and will not be elaborated here.

[0249] In some embodiments, the liquid-cooled hard disk bracket 300 further includes a second plate surface 300b, and the second plate surface 300b is disposed opposite to the first plate surface 300a along the thickness direction z of the cold plate 110. In other words, the second plate surface 300b and the first plate surface 300a are arranged in parallel at intervals.

[0250] At this time, the number of brackets 170 configured on the liquid-cooled hard disk bracket 300 may be two. The two brackets may be denoted as a first split bracket 170a and a second split bracket 170b. The first split bracket 170a is connected to the inner wall of the first plate surface 300a, and the second split bracket 170b is connected to the inner wall of the second plate surface 300b.

[0251] In order to enable the elastic member to protrude from the liquid-cooled hard disk bracket 300 and then contact the cold plate 110, through holes 322 are also formed on the second plate surface 300b. The elastic member protrudes from the liquid-cooled hard disk bracket 300 through the through holes 322, so as to elastically contact the cold plate 110.

[0252] Among them, the technical solution of the through holes 322 on the second plate surface 300b and the elastic members on the second split bracket 170b may refer to the implementation manner of the through holes 322 on the first plate surface 300a and the elastic members on the bracket 170 described above, and will not be elaborated here.

[0253] Through the above solution, brackets 170 are connected to both the first plate surface 300a and the second plate surface 300b of the liquid-cooled hard disk bracket 300. The elastic members on the two brackets 170 protrude from the through holes 322 on the first plate surface 300a and the second plate surface 300b, and the elastic members on the two brackets 170 elastically contact the adjacent cold plates 110 respectively, so as to realize the elastic contact between the two largest opposite surfaces of the hard disk 410 and the adjacent cold plates 110, increasing the elastic contact area between the hard disk 410 and the cold plates 110 to twice that of single-sided elastic contact, increasing the heat transfer area, and improving the heat dissipation efficiency of the hard disk.

[0254] In some embodiments, the bracket 170 can be made of ultra-thin metal sheet metal, Series 1 aluminum, or PI film. Such materials have good thermal conductivity and can withstand multiple frictions without being cut. The surface of the ultra-thin bracket 170 is relatively soft and can closely adhere to the hard disk module as the flatness of the surface changes, avoiding the problem of less contact area caused by hard contact between the cold plate 110 and the hard disk module, such as line contact or point contact. This enhances the contact area and improves the heat dissipation efficiency. In addition, due to the good softness of the bracket 170, it supports the hard disk module to be inserted and removed from the accommodating cavity 150 multiple times.

[0255] Among them, the thickness of the Series 1 aluminum can be 0.15 millimeters, and the thickness of the PI film can also be 0.15 millimeters.

[0256] In some embodiments, the liquid-cooled hard disk bracket 300 further includes a third plate surface 300c and a fourth plate surface 300d, and the third plate surface 300c and the fourth plate surface 300d are oppositely arranged along the first direction x of the cold plate 110. In other words, the first plate surface 300a, the fourth plate surface 300d, the second plate surface 300b, and the third plate surface 300c are sequentially connected to form the liquid-cooled hard disk bracket 300, and enclose to form a loading cavity 321.

[0257] It should be noted that the above description of the first plate surface 300a to the fourth plate surface 300d is only used to illustrate the structure of the liquid-cooled hard disk bracket 300. In some embodiments, the liquid-cooled hard disk bracket 300 is obtained by bending a sheet metal part and then buckling at the docking position.

[0258] In some embodiments, the two plate surfaces that need to be buckled after the sheet metal part is bent can correspond to the first plate surface 300a and the third plate surface 300c. A first buckle 325 is formed on the first plate surface 300a, and a second buckle 326 is formed on the third plate surface 300c. The first buckle 325 and the second buckle 326 are buckled to form the liquid-cooled hard disk bracket 300.

[0259] In some embodiments, the first buckle 325 is configured as a square frame structure with a hollow middle position, and the hollow area is used to insert the second buckle 326. The first buckle 325 can be realized in the following way: the first buckle 325 can extend from the end surface of the first plate surface 300a towards the third plate surface 300c once. After the first extension, a part of the end surface on the extended end surface continues to extend towards the third plate surface 300c a second time, and a hole is dug in the structure formed by the second extension, and this hole is the hollow area.

[0260] It can be understood that two first buckles 325 can be formed on the first plate surface 300a along the second direction y, and the construction method of each first buckle 325 can refer to the implementation method of the above first buckle 325.

[0261] In some embodiments, the second buckle 326 is configured as a bump, and the shape and size of the bump match those of the hollow area, so that the bump can be embedded in the hollow area.

[0262] In some examples, the shape of the hollow area is square, so the shape of the bump is also square. The square size of the hollow area is consistent with the dimension of the bump in the direction.

[0263] In some embodiments, the liquid-cooled hard disk bracket 300 further includes a grounding member 327. When the hard disk 410 is loaded into the loading cavity 321, the hard disk 410 contacts the liquid-cooled hard disk bracket 300, and the grounding member 327 of the liquid-cooled hard disk bracket 300 contacts the liquid-cooled hard disk frame, so as to realize the contact between the hard disk 410 and the liquid-cooled hard disk frame and achieve the grounding of the hard disk 410.

[0264] In some embodiments, the grounding member 327 is formed on the third plate surface 300c. The grounding member 327 can be configured as a structure that turns outwards after cutting a notch in the third plate surface 300c, and this turned-out structure is the grounding member 327. When the liquid-cooled hard disk bracket 300 is inserted into the accommodating cavity 150, the grounding member 327 is turned back into the liquid-cooled hard disk bracket 300 to a certain extent after being squeezed by the wall of the accommodating cavity 150, so as to make reliable contact with the wall of the accommodating cavity 150.

[0265] In some embodiments, the liquid-cooled hard disk bracket 300 further includes a hard disk frame handle 330. The hard disk frame handle 330 is slidably connected between the third plate surface 300c and the fourth plate surface 300d along the second direction y of the cold plate 110, and can be abutted between adjacent cold plates 110 when the liquid-cooled hard disk bracket 300 is inserted into the accommodating cavity 150.

[0266] In some examples, the hard disk frame handle 330 is provided with a sliding strip, and the sliding strip extends into the sliding groove in the third plate surface 300c. Through the cooperation of the sliding strip and the sliding groove, the relative sliding of the hard disk frame handle 330 with respect to the third plate surface 300c and the fourth plate surface 300d is realized. In this way, before the liquid-cooled hard disk bracket 300 needs to be loaded into the accommodating cavity 150, the hard disk frame handle 330 is pulled out by using the cooperation of the sliding strip and the sliding groove; after the liquid-cooled hard disk bracket 300 needs to be loaded into the accommodating cavity 150, the hard disk frame handle 330 is slid to be close to the third plate surface 300c and the fourth plate surface 300d by using the cooperation of the sliding strip and the sliding groove, and finally abuts between adjacent cold plates 110.

[0267] In some embodiments, snap rings are provided on opposite sides of the hard disk frame handle 330 along the thickness direction z of the cold plate 110. The snap rings can bounce along the thickness direction z of the cold plate, so that when the liquid-cooled hard disk bracket 300 is inserted into the accommodating cavity 150, the snap rings are pressed by the cold plate 110 and bounce to abut against the cold plate 110.

[0268] In some examples, the snap ring can extend along the first direction x of the cold plate 110. The dimension of the tension spring along the first direction x of the cold plate 110 is set according to the actual situation, and the embodiments of the present application do not limit the dimension of the snap ring.

[0269] In some embodiments, the elastic member is configured as an elastic convex hull 172. The elastic convex hull 172 is configured to protrude outward from the surface of the bracket 170. The top surface of the elastic convex hull 172 is used to contact the hard disk 410 or the cold plate 110. This structural design of integrally forming the elastic convex hull 172 can simplify the manufacturing process, reduce costs, avoid the problem of gaps between the elastic convex hull 172 and the bracket 170, and achieve the stability of the elastic connection between the elastic convex hull 172, the hard disk 410, and the cold plate 110.

[0270] In some embodiments, the elastic convex hull 172 is formed by extending outward from one side surface of the bracket 170 facing the hard disk 410 and / or the cold plate 110.

[0271] In some embodiments, the elastic convex hull 172 is made by the process of punching convex hulls, with uniform elasticity, more suitable for mass production, and lower costs.

[0272] In some embodiments, the elastic convex hulls 172 are distributed in an array on the bracket 170. The distribution area of the elastic convex hulls 172 corresponds to the area of the cooling cavity 111 of the cold plate 110 to achieve heat transfer from the elastic convex hulls 172 to the liquid in the cooling cavity 111.

[0273] Continue to refer to Figure 14 and Figure 15 , in some embodiments, the bracket 170 is connected to the surface of the cold plate 110 for dissipating heat from the hard disk module, that is, the surface of the cold plate 110 along its own thickness direction z. The elastic convex hull 172 protrudes toward the accommodation cavity 150. At this time, when the hard disk module is inserted into the accommodation cavity 150, the top surface of the elastic convex hull 172 is in elastic contact with the hard disk 410, thereby achieving elastic contact between the hard disk 410 and the cold plate 110.

[0274] In some embodiments, the bracket 170 is bonded to the cold plate 110. Specifically, the adhesive is coated on the area of the bracket 170 that does not correspond to the elastic convex hull 172. The bracket 170 and the cold plate 110 are bonded through the adhesive. When the adhesive is configured as a tearable adhesive tape, it is convenient to disassemble the bracket 170 from the cold plate 110.

[0275] In some embodiments, the bracket 170 is welded to the cold plate 110. Specifically, the solder is coated on the area of the bracket 170 that does not correspond to the elastic convex hull 172, and then the bracket 170 and the cold plate 110 are welded, with a firm connection.

[0276] Continue to refer to Figure 16 and Figure 17, in some embodiments, the bracket 170 is connected to the inner wall of the liquid-cooled hard disk bracket 300, and the elastic convex hull 172 protrudes from the liquid-cooled hard disk bracket 300. At this time, when the hard disk module is inserted into the accommodating cavity 150, the top surface of the elastic convex hull 172 is in elastic contact with the cold plate 110, so as to realize the elastic contact between the hard disk 410 and the cold plate 110.

[0277] Among them, the technical solution of the connection between the bracket 170 and the liquid-cooled hard disk bracket 300 can refer to the foregoing implementation manner of the connection between the bracket 170 and the liquid-cooled hard disk bracket 300, and will not be elaborated herein.

[0278] In order to optimize the heat transfer path between the hard disk module and the coolant, in some embodiments, a concave pit 173 is formed in the area of the bracket 170 facing away from the elastic convex hull 172; a heat-conducting pad 171 is arranged in the concave pit 173. The heat-conducting pad 171 is used to fill the gap between the bottom of the concave pit 173 and the cold plate 110 or the hard disk 410 in the thickness direction z of the cold plate 110, so as to realize the heat transfer between the hard disk module and the coolant along the thickness direction z of the cold plate 110, shorten the heat transfer path, and improve the heat dissipation efficiency.

[0279] In some embodiments, the heat-conducting pad 171 is obtained by condensing a liquid with heat-conducting function.

[0280] In order to ensure that the outer side of the heat-conducting pad 171 relative to the concave pit 173 can stably contact the cold plate 110 or the hard disk 410, in some embodiments, the surface of the outer side of the heat-conducting pad 171 relative to the concave pit 173 extends beyond the surface of the bracket 170 facing away from the elastic convex hull 172.

[0281] In some examples, the surface of the outer side of the heat-conducting pad 171 relative to the concave pit 173 extending beyond the surface of the bracket 170 facing away from the elastic convex hull 172 can be realized in the following way: the dimension of the heat-conducting pad 171 in the thickness direction z of the cold plate 110 is greater than the dimension of the concave pit 173 in the thickness direction z of the cold plate 110.

[0282] In some examples, the extending dimension of the surface of the outer side of the heat-conducting pad 171 relative to the concave pit 173 extending beyond the surface of the bracket 170 facing away from the elastic convex hull 172 can be 0.7 mm, 0.8 mm or other dimensions. The extending dimension of the heat-conducting pad 171 can be comprehensively determined according to the elastic coefficient of the heat-conducting pad 171. The embodiments of the present application do not limit the extending dimension of the heat-conducting pad 171.

[0283] In some embodiments, when the top surface of the elastic convex hull 172 is used to contact the hard disk 410, that is, when the bracket 170 is connected to the cold plate 110, the side of the heat-conducting pad 171 facing outward relative to the pit 173 is used to contact the cold plate 110, reducing costs. In addition, by using the bracket 170, a thermal connection between the cold plate 110 and the hard disk module is established using the elastic convex hull 172 and the heat-conducting pad 171. The contact surface between the hard disk module and the cold plate 110 is divided into several units, reducing the problem that the heat-conducting pad 171 flows and jams during the insertion of the hard disk module due to large-area contact friction, and improving the convenience of inserting the hard disk module into the accommodation cavity 150.

[0284] In some embodiments, when the top surface of the elastic convex hull 172 is used to contact the cold plate 110, that is, when the bracket 170 is connected to the liquid-cooled hard disk bracket 300, the side of the heat-conducting pad 171 facing outward relative to the pit 173 is used to contact the hard disk 410, and the first plate surface 300a or the second plate surface 300b can press around the pit 173, thereby preventing the heat-conducting pad 171 from overflowing during the molding process, which is beneficial to improving the efficiency and quality of setting the heat-conducting pad 171.

[0285] In some embodiments, heat dissipation teeth are provided on the largest surface of the hard disk 410, and the top surface of the elastic convex hull 172 or the side of the heat-conducting pad 171 facing outward relative to the pit 173 contacts the heat dissipation teeth of the hard disk 410, so as to transfer the heat of the hard disk 410 to the elastic convex hull 172 or the heat-conducting pad 171 through the heat dissipation teeth. In this way, without changing the heat dissipation structure of the hard disk 410, the liquid-cooling system provided by the embodiments of the present application can be applied, improving the applicable scenarios of the server 1000.

[0286] In some embodiments, the distribution area of the heat-conducting pad 171 on the cold plate 110 can be the same as the distribution area of the heat dissipation teeth on the hard disk 410.

[0287] Figure 20 The structural schematic diagram of the liquid-cooled hard disk frame including the backplane mounting bracket provided by some embodiments of the present application. As Figure 20 shown, in some embodiments, the server 1000 further includes a backplane mounting bracket 180, and the backplane mounting bracket 180 is fixedly connected to the outermost cold plate 110 as the support structure of the entire liquid-cooled hard disk frame 100.

[0288] Among them, the backplane mounting bracket 180 can be fixedly connected to the outermost cold plate 110 close to the water outlet 142. In other words, the backplane mounting bracket 180 is located at the bottom of the liquid-cooled hard disk frame 100 to support the entire liquid-cooled hard disk frame 100.

[0289] In some embodiments, the backplane mounting bracket 180 can be fixedly connected to the cold plate 110 by screws.

[0290] In some embodiments, the backplane mounting bracket 180 can be fixedly connected to the cold plate 110 by an adhesive.

[0291] In some embodiments, the backplane mounting bracket 180 is fixedly welded to the cold plate 110.

[0292] In some examples, the backplane mounting bracket 180 is fixedly connected to the outer side of the cold plate 110 facing outward in the thickness direction z, so that the backplane mounting bracket 180 is located on the outermost side of the entire liquid-cooled hard disk frame 100, thereby supporting the entire liquid-cooled hard disk frame 100.

[0293] Figure 21 Schematic structural diagram of a liquid-cooled hard disk frame including a backplane provided by some embodiments of the present application; Figure 22 is Figure 21 The enlarged structural diagram at position C in. As Figure 19 and Figure 20 As shown, in some embodiments, the liquid-cooled hard disk frame 100 further includes a backplane 190, and the backplane 190 is located on one side of the cold plate 110 along its own second direction y. In this way, the hard disk module is inserted into the accommodation cavity 150 from the side of the cold plate 110 without the backplane 190 along the second direction y, and is fixed to the liquid-cooled hard disk frame 100 by using the hard disk frame handle 330 of the liquid-cooled hard disk bracket 300, thereby realizing the positioning of the hard disk module.

[0294] In some embodiments, at least one layer of middle partition 160 is formed with a tail hook 163 on the same side of the cold plate 110 in the second direction y. A limiting member 164 is formed on the side of the backplane mounting bracket 180 facing the double-sided backplane 190, and a mounting hole 191 corresponding to the tail hook 163 is formed on the backplane 190; one end of the backplane 190 is embedded in the limiting member 164, and the tail hook 163 passes through the mounting hole 191 to realize the assembly of the backplane 190 to the liquid-cooled hard disk frame 100.

[0295] Among them, at least one layer of middle partition 160 can be understood as: the middle partition 160 provided between two adjacent cold plates 110.

[0296] In some embodiments, the tail hook 163 is configured to be formed by extending outward from a side wall of the middle partition 160 along the second direction y of the cold plate 110 and then folding back in a direction away from the backplane mounting bracket 180.

[0297] In some embodiments, the tail hook 163 can also be formed on the inlet water distributor 130 and the outlet water distributor 140. The technical solution of setting the tail hook 163 on the inlet water distributor 130 and the outlet water distributor 140 can refer to the implementation manner of forming the tail hook 163 on the middle partition 160, and will not be elaborated here.

[0298] As Figure 20As shown, in some embodiments, the limiting member 164 may be composed of two sub-limiting members. Both sub-limiting members extend along the first direction x of the cold plate 110 and are arranged on the backplane mounting bracket 180 at a preset distance d2. The preset distance d2 is equal to the thickness dimension of the backplane 190. Accordingly, a limiting space is formed between the two sub-limiting members, and the limiting space is used to accommodate the backplane 190.

[0299] Based on the same concept, an embodiment of the present application further provides a liquid-cooled hard disk frame. The liquid-cooled hard disk frame includes at least two cold plates arranged at intervals and opposite to each other, an inlet water distributor, and an outlet water distributor. A cooling cavity is integrally formed in the cold plate for the coolant to flow through. A receiving cavity is formed between at least two cold plates for inserting a hard disk module. The inlet end of the cooling cavity is communicated with the flow channel of the inlet water distributor so that the coolant flows into the cooling cavity from the inlet water distributor.

The outlet end of the cooling cavity is communicated with the flow channel of the outlet water distributor so that the coolant flowing through the cooling cavity is collected by the outlet water distributor. Among them, at least two cold plates are connected between the inlet water distributor and the outlet water distributor.
