Description

[Technical Field]

[0001] This invention relates to the technical field of liquid cooling for equipment, and more particularly to a chassis and server. [Previous Technology]

[0002] With the development of the Internet of Things, edge computing, and 5G applications, data AI is driving global computing power into a period of rapid growth. Traditional air cooling methods can no longer meet the heat dissipation requirements of computer cases. Liquid cooling technology, due to its high-efficiency heat dissipation capacity, low energy consumption, low noise, and space saving, has become a key technology for solving the problem of high heat density heat dissipation and is crucial for promoting the sustainable development of data centers and related high-performance computing facilities. Oil cooling is a liquid cooling technology that uses a liquid (oil) circulating cooling medium. Oil can absorb heat better than air, thus supporting denser chip arrangement. In immersion liquid cooling solutions, more and more manufacturers are choosing oil as the coolant. Oil is a relatively inexpensive insulating coolant that can directly contact electronic components on servers without short-circuiting, thus serving as the coolant in immersion liquid cooling systems.

[0003] In traditional technology, the chassis has a complex structural design and an unreasonable layout, which not only poses a safety hazard of oil leakage, but also results in low utilization of internal space, leading to a large overall size and occupying a lot of installation space. [Summary of the Invention]

[0004] Based on this, it is necessary to provide a chassis and server to solve the potential safety hazards of oil leakage and reduce the overall size and installation space occupied.

[0005] In a first aspect, the present invention provides a chassis comprising:

[0006] The box body is provided with a first partition inside the box body. The first partition divides the inner cavity of the box body into an immersion area and a heat dissipation area. The first partition has a liquid outlet and a liquid return outlet. The liquid outlet and the liquid return outlet connect the immersion area and the heat dissipation area.

[0007] Functional component, the functional component being installed in the immersion zone and immersed in the cooling oil in the immersion zone;

[0008] A heat dissipation assembly, wherein the heat dissipation assembly is installed within the heat dissipation zone, and the heat dissipation assembly is used to drive the cooling oil to circulate between the immersion zone and the heat dissipation zone, so as to allow the cooling oil to exchange heat with the external environment; and

[0009] Box lid, the box lid sealing cover is provided at the opening of the box body; wherein, the box body adopts an integral structure.

[0010] In the chassis of this solution, the first partition divides the inner cavity of the chassis into an immersion zone and a heat dissipation zone. The functional components and the heat dissipation components are independently installed in the immersion zone and the heat dissipation zone, respectively. During operation, the functional components generate high-temperature heat. Since the functional components are immersed in the cooling oil in the immersion zone, the cooling oil absorbs the generated high-temperature heat, thereby cooling the functional components. The cooling oil that has absorbed heat flows into the heat dissipation zone through the outlet, and then exchanges heat with the external environment through the heat dissipation components to dissipate the heat and restore the cooling oil to normal temperature. The heat dissipation components then drive the cooling oil back through the return port. The liquid flows to the immersion zone for further immersion cooling of the functional components, ensuring continuous and effective heat dissipation and guaranteeing operational safety. Compared to existing technologies, the chassis features a simple and rational partitioning and component arrangement, with smooth cooling oil circulation, significantly improving cooling efficiency and making efficient use of internal space, thus reducing chassis size and installation space requirements. Furthermore, the integrated chassis design, sealed with the cover, reduces the number of parts, eliminates potential leaks and hazards, and greatly enhances the overall sealing reliability.

[0030] Referring to FIG.

[0031] Referring to FIG. Among them, the box body 10 adopts an integrated structure. It can be understood that the box body 10 can be formed by adopting a single integral plate, processed by bending, welding and other processes, with excellent structural properties and sealing capabilities.

[0032] The box body 10 is of rectangular construction, and one of the large faces of the box body 10 (i.e., the side with the largest area) forms an opening for the functional assembly 30 and the cooling assembly 40 to be installed or removed from the box body 10 .

[0033] Refer to Figures 3 and 6, the interior of the box 10 is provided with a first bulkhead 20, the first bulkhead 20 separates the inner cavity of the box 10 into submersion zone 11 and radiator zone 12, the first bulkhead 20 is opened with an outlet 21 and a return port 22, the outlet 21 and the return port 22 connect the submerged area 11 with the radiator area 12; Piece 30 is installed within the submerged zone 11 and immersed in the cooling oil within the submerged zone 11;

[0034] It should be stated that the part of the case lid 50 corresponding to the submerged area 11 is provided as an observation area, which adopts a transparent material to facilitate the user to observe the internal situation of the chassis 100 from the outside.

[0035] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: In the chassis 100 of this solution, the first partition 20 divides the inner cavity of the chassis 10 into an immersion area 11 and a heat dissipation area 12. The functional component 30 and the heat dissipation component 40 are respectively independently installed in the immersion area 11 and the heat dissipation area 12. During operation, the functional component 30 generates high-temperature heat. Since the functional component 30 is immersed in the cooling oil in the immersion area 11, the cooling oil absorbs the generated high-temperature heat, thereby cooling the functional component 30. The cooling oil that has absorbed the heat flows into the heat dissipation area 12 through the outlet 21, and then exchanges heat with the external environment through the heat dissipation component 40 to dissipate the heat and restore the cooling oil to normal temperature. The component 40 drives the cooling oil to flow back to the immersion zone 11 through the return port 22 so as to perform immersion liquid cooling treatment on the functional component 30 again, thereby ensuring that the heat generated by the functional component 30 is continuously and effectively dissipated and ensuring operational safety. Compared with the prior art, on the one hand, the partition and component arrangement structure of the chassis 100 is simple and reasonable, the cooling oil circulation is smooth, which greatly improves the cooling efficiency of the chassis 100 and makes reasonable use of the internal space of the chassis 100, which helps to reduce the size of the chassis 100 and the installation space occupied. On the other hand, the chassis 100 adopts an integrated structure design and is sealed and assembled with the cover 50, which reduces the number of parts, eliminates potential leakage points and leakage hazards, and greatly improves the sealing reliability of the whole machine.

[0036] It is understandable that by precision machining the opening wall of the box 10 and the side of the box cover 50, the opening wall and the side can be tightly and seamlessly fitted, and the box cover 50 and the box 10 can be sealed and assembled. However, this requires very high machining accuracy and usually requires machining equipment with higher machining accuracy, which increases the machining cost.

[0037] It should be noted that the functional components 30 installed in the immersion zone 11 are heat sources, including but not limited to motherboard, hard drive, power supply, CPU, DIMM, PCIe, etc.

[0038] In view of this, based on the above embodiment, the chassis 100 further includes a sealing ring, which is disposed on the side of the cover 50 facing the chassis 10, and the sealing ring seals against the wall between the cover 50 and the opening. By deforming the sealing ring to fill the annular gap between the cover 50 and the opening wall, an excellent sealing effect can be obtained. Moreover, this sealing method has a simple structure, high reliability, and low implementation cost.

[0039] For example, the sealing ring is an O-ring. To improve the installation and positioning accuracy of the sealing ring, an annular groove can be machined on the opening wall of the housing 10 and / or the side of the cover 50, and the sealing ring is installed in the annular groove to achieve the positioning effect of the sealing ring.

[0040] Please continue to refer to Figure 3. In one embodiment, the heat dissipation assembly 40 includes a circulation pump 41, a radiator 42 and a cooling fan 43. The radiator 42 is directly connected to the liquid outlet 21 or connected through a pipeline. The radiator 42 is directly connected to the circulation pump 41 or connected through a pipeline. The circulation pump 41 is directly connected to the liquid return port 22 or connected through a pipeline. The cooling fan 43 is configured to cooperate with the radiator 42.

[0041] During operation, the cooling oil that has absorbed the high temperature heat generated by the functional component 30 flows into the radiator 42 and can exchange heat with the air through the radiator 42. The air that has absorbed the heat flows out of the housing 10 quickly under the drive of the cooling fan 43 and is discharged into the external environment, thereby cooling the cooling oil so that the cooling oil has the ability to circulate and cool the functional component 30.

[0042] Please continue to refer to Figures 1 and 2. Further, the cover 50 and / or the body 10 are provided with an air inlet 50a, which connects the external environment with the heat dissipation area 12. The body 10 is provided with an air outlet 13, which connects the external environment with the heat dissipation area 12. With this configuration, the air inlet 50a, the heat dissipation area 12, and the air outlet 13 form a circulating airflow path with the external environment, so that the low-temperature air in the external environment can continuously flow into the heat dissipation area 12 to exchange heat with the cooling oil in the radiator 42, and then be discharged from the body 10 through the air outlet 13.

[0043] Please continue to refer to Figures 3 and 6. In addition, to facilitate regular maintenance or repair of the heat sink 42 and the cooling fan 43, in one embodiment, the chassis 100 further includes a first frame 60 and a second frame 60a. The heat sink 42 is mounted on the first frame 60, and the cooling fan 43 is mounted on the second frame 60a. Both the first frame 60 and the second frame 60a can be detachably installed on the chassis 10. That is to say, the first frame 60 and the second frame 60a act as carriers and can be installed or removed together with the heat sink 42 and the cooling fan 43, respectively, making the installation and removal operations more convenient.

[0044] Please continue to refer to Figures 3 and 4. Based on any of the above embodiments, the first partition 20 includes a first plate body 23 and a first wire clamp 24. The first plate body 23 is provided with a first wire groove, and the first wire clamp 24 is provided with a second wire groove. The first wire clamp 24 is installed on the first plate body 23 so that the first wire groove and the second wire groove surround to form a first wire passage hole 25. The functional component 30 includes a main control board. The cables electrically connected to the main control board and the heat sink 42 and the cooling fan 43 can be installed through the first wire passage hole 25, so that the main control board can control the heat sink 42 and the cooling fan 43, reducing the difficulty of wiring and simplifying the wiring structure.

[0045] It should be noted that the diameter of the first wire hole 25 should be the same as or similar to the diameter of the cable, so that the hole wall of the first wire hole 25 is in close contact with the outer wall of the cable to obtain a reliable seal, so as to prevent the cooling oil from leaking into the radiator 42 and the cooling fan 43, causing the radiator 42 and the cooling fan 43 to malfunction.

[0046] Please continue to refer to Figures 3 and 5. In another embodiment, a second partition 70 is also provided inside the housing 10. The second partition 70 divides the inner cavity of the housing 10 into a connection area 14. The housing 10 includes a connection plate 15a, which has a connection port 15 that communicates with the connection area 14. The connection area 14 is provided with plug-in ports, each corresponding to a connection port 15. Each plug-in port is electrically connected to the main control board, allowing the chassis 100 to connect to various peripheral devices, such as keyboards, mice, and monitors, through the plug-in ports.

[0047] It is easy to understand that the connection area 14 is specifically the I / O area, and the corresponding connection board 15a is the I / O board.

[0048] Specifically, the second partition 70 includes a second plate body 71 and a second wire clamp 72. The second plate body 71 is provided with a third wire groove, and the second wire clamp 72 is provided with a fourth wire groove. The second wire clamp 72 is mounted on the second plate body 71 so that the third wire groove and the fourth wire groove surround to form a second wire passage hole 73. The cables electrically connected to the main control board and each plug-in port can be installed through the second wire passage hole 73, so that the main control board can transmit signals and commands with each peripheral device, reducing the difficulty of wiring and simplifying the wiring structure.

[0049] It should be noted that the diameter of the second wire hole 73 should be the same as or similar to the diameter of the cable, so that the hole wall of the first wire hole 25 is in close contact with the outer wall of the cable to obtain a reliable seal, so as to prevent the cooling oil from leaking into the radiator 42 and the cooling fan 43, causing the radiator 42 and the cooling fan 43 to malfunction.

[0050] In yet another embodiment, the functional component 30 includes at least a hard drive, a power supply, a third load frame 60b and a fourth load frame 60c Loading the hard disk and power supply through the third loading frame 60b and fourth loading frame 60c, respectively, facilitates loading, unloading and maintenance of the hard disk and power supply by installing and removing the third loading frame 60b and fourth loading frame 60c.

[0051] It should be noted that the description of the present invention concerning the installation of two elements may be, but is not limited to, any one of screw, snap, bond, magnetic connection, and the like. For example, for ease of operation, screw jointing is preferably adopted.
