Description

Technical Field

[0001] The present application relates to the technical field of equipment liquid cooling, and in particular to a chassis and a server. Background Art

[0002] With the development of the Internet of Things, edge computing and 5G applications, data AI has driven global computing power into a period of rapid growth. Traditional air cooling can no longer meet the heat dissipation needs of the chassis. Liquid cooling technology has become a key technology for solving high heat density heat dissipation problems due to its high efficiency, low energy consumption, low noise and space saving. It is essential to promote the sustainable development of data centers and related high-performance computing facilities. Oil cooling is a liquid cooling technology that uses liquid (oil) as a circulating cooling medium. Oil can absorb heat better than air, so it can support a tighter chip arrangement. In the immersion liquid cooling solution, more and more manufacturers choose oil as the coolant. Oil is a relatively inexpensive insulating coolant that can be in direct contact with electronic components on the server without short circuiting, and is then used as a coolant in the immersion liquid cooling system.

[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 causes low utilization of the internal space, resulting in a large size of the entire machine and occupying a lot of installation space. Summary of the invention

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

[0005] In a first aspect of the present application, a chassis is provided, comprising:

[0006] A box body, wherein a first partition is arranged 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 is provided with a liquid outlet and a liquid return port, the liquid outlet and the liquid return port connect the immersion area with the heat dissipation area;

[0010] In the chassis of the present solution, a first partition is provided to separate the inner cavity of the box body into an immersion area and a heat dissipation area. The functional components and the heat dissipation components are independently installed in the immersion area and the heat dissipation area respectively. When working, the functional components will generate high-temperature heat. Since the functional components are immersed in the cooling oil in the immersion area, the cooling oil will absorb the generated high-temperature heat and thus cool the functional components. The cooling oil that has absorbed the heat flows into the heat dissipation area through the liquid outlet, and then exchanges heat with the external environment through the heat dissipation component to discharge the heat and restore the cooling oil to normal temperature. The heat dissipation component then drives the cooling oil to flow back to the immersion area through the return port. Areas are set up so that the functional components can be immersed in liquid cooling again, thereby ensuring that the heat generated by the functional components is continuously and effectively dissipated, ensuring work safety; compared with the existing technology, on the one hand, the partition and component setting structure of the chassis are simple and reasonable, and the cooling oil circulates smoothly, which greatly improves the cooling efficiency of the chassis and makes rational use of the internal space of the chassis, which helps to reduce the size of the chassis and the installation space occupancy; on the other hand, the chassis adopts an integrated structural design and is sealed and assembled with the box cover, which reduces the number of parts, eliminates potential leakage points and leakage risks, and greatly improves the sealing reliability of the whole machine.

[0037] See also Figure 1 and Figure 2 , is a chassis 100 shown in an embodiment of the present application, which is specifically a liquid-cooled chassis 100, and the medium involved in the liquid cooling operation can be but is not limited to liquid cooling oil.

[0038] Please continue reading Figure 3, exemplarily, the chassis 100 includes a box body 10, a functional component 30, a heat dissipation component 40 and a box cover 50. The box body 10 adopts an integrated structure. It can be understood that the box body 10 can be formed by a whole plate through bending, welding and other processes, and has excellent structural performance and sealing ability.

[0039] The box body 10 is a rectangular parallelepiped structure, and an opening is formed on one of the large faces (ie, the side face with the largest area) of the box body 10 so that the functional component 30 and the heat dissipation component 40 can be installed in or removed from the box body 10 .

[0040] Please continue reading Figure 3 and Figure 6 A first partition 20 is provided inside the box body 10, and the first partition 20 divides the inner cavity of the box body 10 into an immersion area 11 and a heat dissipation area 12. The first partition 20 is provided with a liquid outlet 21 and a liquid return port 22, and the liquid outlet 21 and the liquid return port 22 connect the immersion area 11 with the heat dissipation area 12; the functional component 30 is installed in the immersion area 11 and immersed in the cooling oil in the immersion area 11; the heat dissipation component 40 is installed in the heat dissipation area 12, and the heat dissipation component 40 is used to drive the cooling oil to circulate between the immersion area 11 and the heat dissipation area 12, so that the cooling oil can exchange heat with the external environment; the box cover 50 sealing cover is arranged at the opening of the box body 10.

[0041] It should be noted that the portion of the case cover 50 corresponding to the immersion area 11 is set as an observation area, and the observation area is made of a transparent material to facilitate the user to observe the internal conditions of the case 100 from the outside.

[0042] In summary, the implementation of the technical solution of this embodiment will achieve the following beneficial effects: in the chassis 100 of this solution, the first partition 20 is set to divide the inner cavity of the box body 10 into an immersion area 11 and a heat dissipation area 12, and the functional component 30 and the heat dissipation component 40 are independently installed in the immersion area 11 and the heat dissipation area 12 respectively. When working, the functional component 30 will generate high-temperature heat. Since the functional component 30 is immersed in the cooling oil in the immersion area 11, the cooling oil will absorb the generated high-temperature heat and thus cool the functional component 30. The cooling oil that has absorbed the heat flows into the heat dissipation area 12 through the liquid outlet 21, and then exchanges heat with the external environment through the heat dissipation component 40 to discharge the heat and restore the cooling oil to normal temperature. The heat dissipation component 40 The cooling oil is then driven to flow back to the immersion area 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 to ensure work safety; compared with the prior art, on the one hand, the partition and component setting structure of the chassis 100 are simple and reasonable, and the cooling oil circulates smoothly, 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 volume of the chassis 100 and the installation space occupied. On the other hand, the chassis 100 adopts an integrated structural design and is sealed and assembled with the box cover 50, which reduces the number of components, eliminates potential leakage points and leakage risks, and greatly improves the sealing reliability of the whole machine.

[0043] It is understandable that by fine-machining the opening wall of the box body 10 and the side of the box cover 50 so that the opening wall and the side are tightly and seamlessly fitted, the box cover 50 and the box body 10 can be sealed and assembled. However, this requires very high machining accuracy and usually requires the use of machining equipment with higher machining accuracy capabilities, which increases the machining cost.

[0044] It should be noted that the functional components 30 immersed and installed in the immersion area 11 are the source of heat generation, including but not limited to the motherboard, hard disk, power supply, CPU, DIMM, Pcie, etc.

[0045] In view of this, on the basis of the above embodiment, the case 100 further includes a sealing ring, which is arranged on the side of the case cover 50 facing the case body 10, and the sealing ring is sealed and abutted between the case cover 50 and the opening wall. The annular gap between the case cover 50 and the opening wall is filled tightly by the deformation of the sealing ring, so that an excellent sealing effect can be obtained, and this sealing method has a simple structure, high reliability, and low implementation cost.

[0046] For example, the sealing ring is an O-type rubber ring. In order to improve the sealing ring installation positioning accuracy, an annular groove can be processed on the opening wall of the box body 10 and / or the side of the box cover 50, and the sealing ring is installed in the annular groove to achieve the sealing ring positioning effect.

[0047] Please continue reading Figure 3 In one embodiment, the heat dissipation assembly 40 includes a circulation pump 41, a radiator 42 and a heat dissipation 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 heat dissipation fan 43 is arranged in conjunction with the radiator 42.

[0048] 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 quickly flows out of the box 10 and is discharged into the external environment under the drive of the cooling fan 43, thereby cooling the cooling oil so that the cooling oil has the ability to circulate and cool the functional component 30.

[0049] Please continue reading Figure 1 and Figure 2 Further, the box cover 50 and / or the box body 10 are provided with an air inlet 50a, which connects the external environment with the heat dissipation area 12, and the box body 10 is provided with an air outlet 13, which connects the external environment with the heat dissipation area 12. In this way, 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 box body 10 through the air outlet 13.

[0050] Please continue reading Figure 3 and Figure 6 In addition, in order to facilitate regular maintenance or repair of the radiator 42 and the cooling fan 43, in one embodiment, the chassis 100 further includes a first carrier frame 60 and a second carrier frame 60a, the radiator 42 is mounted on the first carrier frame 60, the cooling fan 43 is mounted on the second carrier frame 60a, and the first carrier frame 60 and the second carrier frame 60a can be detachably mounted on the box body 10. In other words, the first carrier frame 60 and the second carrier frame 60a act as carriers and can be installed or removed together with the radiator 42 and the cooling fan 43, respectively, making the installation and removal operations more convenient.

[0051] Please continue reading Figure 3 and Figure 4On the basis of any of the above embodiments, the first partition plate 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, the first wire clamp 24 is provided with a second wire groove, and the first wire clamp 24 is installed on the first plate body 23 so that the first wire groove and the second wire groove are enclosed to form a first wire hole 25. The functional component 30 includes a main control board, and the cables electrically connected to the main control board and the radiator 42 and the cooling fan 43 can be installed through the first wire hole 25 to penetrate the first partition plate 20, so that the main control board can control the radiator 42 and the cooling fan 43, reduce the difficulty of wiring, and simplify the wiring structure.

[0052] It should be noted that the aperture of the first wire hole 25 and the diameter of the cable should be the same or similar value so that the hole wall of the first wire hole 25 is close to the outer wall of the cable to obtain a reliable seal, thereby preventing cooling oil from leaking into the radiator 42 and the cooling fan 43, causing the radiator 42 and the cooling fan 43 to malfunction.

[0053] Please continue reading Figure 3 and Figure 5 In addition, in another embodiment, a second partition 70 is further provided inside the box 10, and the second partition 70 separates the inner cavity of the box 10 into a connection area 14, and the box 10 includes a connection plate 15a, and the connection plate 15a is provided with a connection port 15, and the connection port 15 is connected to the connection area 14. The connection area 14 is provided with a plug-in port, each plug-in port is provided in a one-to-one correspondence with the connection port 15, and each plug-in port is electrically connected to the main control board, so that the chassis 100 can be connected to various peripheral devices, such as a keyboard, a computer, a display, etc., through the plug-in port.

[0054] It is easy to understand that the connection area 14 is specifically an I / O area, and correspondingly the connection board 15a is an I / O board.

[0055] Specifically, the second partition plate 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, the second wire clamp 72 is provided with a fourth wire groove, and the second wire clamp 72 is installed on the second plate body 71 so that the third wire groove and the fourth wire groove are enclosed to form a second wire hole 73.

[0056] It should be noted that the aperture of the second wire hole 73 and the diameter of the cable should be the same or similar value so that the hole wall of the first wire hole 25 is close to the outer wall of the cable to obtain a reliable seal, thereby preventing cooling oil from leaking into the radiator 42 and the cooling fan 43, causing the radiator 42 and the cooling fan 43 to malfunction.

[0057] In another embodiment, the functional component 30 at least includes a hard disk, a power supply, a third carrier frame 60b and a fourth carrier frame 60c, the hard disk is installed in the third carrier frame 60b, the power supply is installed in the fourth carrier frame 60c, and the third carrier frame 60b and the fourth carrier frame 60c are both detachably installed on the box body 10.
