Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of servers, and in particular to a cooling assembly, a cooling device and a server. BACKGROUND

[0002] At present, the rapid development of server technology makes high-performance computing possible, but also brings serious heat dissipation challenges. A large number of high-performance integrated circuits (such as central processing units, graphics processing units, etc.) integrated in the server case will generate significant heat when running, which poses a great threat to the stability of the system and the service life of the equipment. High temperature not only leads to performance degradation, increases the failure rate, and even causes permanent damage to critical components, seriously affecting the reliability and data security of the server.

[0003] At present, the heat dissipation method of the server mainly relies on the combination of heat sinks and fans, but this method has limitations. Although the heat sink can directly contact the heat source and absorb heat, due to its solid-state heat dissipation characteristics, the heat dissipation efficiency is limited, especially under high load operation, the heat conduction speed of the heat sink cannot keep up with the heat generation rate of the computing components, resulting in poor heat dissipation effect. In addition, the heat sink often occupies a large space, hindering the free circulation of air inside the case, reducing the heat dissipation efficiency of the server. More importantly, the complex structure design and manufacturing process of the heat sink result in high production cost, which not only increases the initial investment of the server, but also to a certain extent limits the further optimization and innovation of the heat dissipation technology.

[0004] With the continuous improvement of server performance, the requirement for heat dissipation technology also increases. The heat dissipation technology in the prior art is not capable of dealing with high-density and high-heat computing environments, and these limitations cannot meet the demand for stable operation and long service life of high-performance servers.

[0059] Embodiment one

[0060] As Figures 1 to 11As shown, the present application provides a cooling assembly, comprising: a housing 1, the housing 1 having a receiving cavity 10 and a housing inlet 11 and a housing outlet 12 respectively communicating with the receiving cavity 10; a flow divider 2, the flow divider 2 being arranged in the receiving cavity 10 to divide the receiving cavity 10 into an inner cavity 101 located inside the flow divider 2 and an outer cavity 102 located outside the flow divider 2, the inner cavity 101 being used to accommodate at least part of a component to be cooled 1500, the housing inlet 11 communicating with the inner cavity 101, the housing outlet 12 communicating with the outer cavity 102, the flow divider 2 being provided with a communication hole 20 for communicating the inner cavity 101 and the outer cavity 102; a cooling structure 3, at least part of the cooling structure 3 being arranged in the inner cavity 101 and communicating with the housing inlet 11 to spray the cooling liquid flowing in from the housing inlet 11 to the inner cavity 101.

[0061] In the cooling assembly of the present application, the cooling liquid enters the inner cavity 101 through the housing inlet 11, contacts and absorbs heat from the component to be cooled 1500, and evaporates into vapor under the action of heat, the vapor enters the outer cavity 102 through the communication hole 20, and then flows out from the housing outlet. In this way, the heat of the component to be cooled 1500 can be effectively absorbed by the evaporation and condensation of the cooling liquid in the inner cavity 101, and the smooth flow of the cooling liquid from the inner cavity 101 to the outer cavity 102 can be ensured by providing the communication hole 20, realizing the flow of the cooling liquid, so that the temperature of the component to be cooled 1500 is effectively controlled, the cooling effect is enhanced, and the heat dissipation efficiency is improved. When the component to be cooled 1500 is the central processor of the server, the running stability and working efficiency of the server are improved, the problem of low heat dissipation efficiency of the heat dissipation mode of the server in the related art, which cannot meet the needs of the server, is solved, the problem of the cooling fin for the central processor of the server in the related art often hindering the circulation of air and the relatively complex structure design, which leads to high production cost, is solved, and the rapid cooling of the cooling liquid is ensured.

[0062] Specifically, the cooling assembly of the present application can more effectively spray the cooling liquid to the component to be cooled through the synergistic effect of the housing, the flow divider and the cooling structure, improve the heat dissipation efficiency, and the vapor flowing out from the housing outlet can be condensed and recycled to be cooled again into cooling liquid, and the cooled cooling liquid can also enter the housing 1 again through the housing inlet 11 to be recycled.

[0063] In an embodiment of the present application, the housing 1 includes a socket 14 communicating with the inner cavity 101 of the receiving cavity 10, one end of the component to be cooled 1500 can be inserted into the inner cavity 101 through the socket 14, and the other end of the component to be cooled 1500 is used to connect with other components.

[0064] As Figures 1 to 11As shown, the cooling structure 3 comprises a first drainage pipe 31 connected with a drainage pipe 32, the first drainage pipe 31 is arranged at the housing inlet 11, and the drainage pipe 32 is arranged in the inner cavity 101 for spraying the cooling liquid to the inner cavity 101.

[0065] In this way, the cooling liquid is first introduced from the housing inlet 11 through the first drainage pipe 31, and then uniformly sprayed on the component to be cooled 1500 through the drainage pipe 32, which increases the flowability and spraying range of the cooling liquid, increases the contact area of the cooling liquid with the component to be cooled 1500, thereby improving the heat dissipation efficiency and cooling effect of the component to be cooled 1500, and reducing the consumption of the cooling liquid.

[0066] As shown in Figure 5 and Figure 11 , the first drainage pipe 31 comprises a fixed pipe section 311 and a rotating pipe section 312 connected with each other, one end of the fixed pipe section 311 away from the rotating pipe section 312 passes through the housing inlet 11 to the outside of the housing 1, the other end of the rotating pipe section 312 away from the fixed pipe section 311 is connected with the drainage pipe 32, and the rotating pipe section 312 is rotatably arranged relative to the fixed pipe section 311 to drive the drainage pipe 32 to rotate relative to the fixed pipe section 311.

[0067] In this way, the rotation of the rotating pipe section 312 drives the drainage pipe 32 to rotate, which can automatically adjust the spraying direction of the cooling liquid, improve the contact efficiency of the cooling liquid with the component to be cooled 1500, and further improve the heat dissipation effect, adapt to the component to be cooled 1500 at different positions, and improve the adaptability and flexibility of the cooling assembly.

[0068] Specifically, a rotating connection member such as a bearing is arranged between the fixed pipe section 311 and the rotating pipe section 312.

[0069] As shown in Figure 11 , the rotating pipe section 312 comprises a middle pipe body 3121 and a plurality of branch pipe bodies 3122 connected with the middle pipe body 3121 respectively, and the plurality of branch pipe bodies 3122 are arranged at intervals around the middle pipe body 3121; the number of the drainage pipes 32 is plural, and the plurality of drainage pipes 32 are connected with the plurality of branch pipe bodies 3122 one by one. The rotating pipe section 312 of the present application realizes the spraying of the cooling liquid in multiple directions through the combination of the middle pipe body 3121 and the plurality of branch pipe bodies 3122, further improves the contact area and cooling efficiency of the cooling liquid with the component to be cooled 1500, makes the distribution of the cooling liquid more uniform, improves the cooling effect, reduces the consumption of the cooling liquid, and improves the adaptability and flexibility of the cooling assembly.

[0070] Specifically, the rotating pipe section 312 comprises a middle pipe body 3121 and two branch pipe bodies 3122 connected with the middle pipe body 3121 respectively, and the plurality of branch pipe bodies 3122 are located at opposite sides of the middle pipe body 3121 respectively to jointly form a "T" shaped rotating pipe section 312; the number of the liquid discharge pipes 32 is two, and the two liquid discharge pipes 32 are connected with the two branch pipe bodies 3122 respectively.

[0071] As shown in Figure 11 , the liquid discharge pipe 32 comprises a main pipe body 321 and a plurality of branch pipe bodies 322 arranged on the main pipe body 321, the main pipe body 321 is used for connecting with the first drainage pipe 31, and each branch pipe body 322 is used for spraying the cooling liquid, which realizes the multi-point spraying of the cooling liquid, further improves the contact area and cooling efficiency of the cooling liquid with the component 1500 to be cooled, makes the distribution of the cooling liquid more uniform, improves the cooling effect, reduces the consumption of the cooling liquid, and improves the adaptability and flexibility of the cooling assembly.

[0072] Preferably, the liquid discharge pipe 32 further comprises a liquid discharge spoiler 323 arranged in the branch pipe body 322, and the spraying of the cooling liquid can be more uniform through the spoiler effect of the liquid discharge spoiler 323, which improves the heat exchange efficiency of the cooling liquid with the component 1500 to be cooled, thereby improving the cooling effect and reducing the consumption of the cooling liquid.

[0073] Specifically, the liquid discharge spoiler 323 can be a spiral spoiler plate.

[0074] As shown in Figure 3 , Figure 5 , Figures 6 to 8 and Figure 10 , the flow divider 2 comprises a top bent plate 21 and two side plates 22 connected with the top bent plate 21 respectively, and the two side plates 22 are arranged at opposite sides of the top bent plate 21 respectively to jointly form a flow divider 2 with a cross section of inverted U type.

[0075] In this way, the structure with a cross section of inverted U type formed by the combination of the top bent plate 21 and the two side plates 22 can effectively separate the containing cavity 10 into the inner cavity 101 and the outer cavity 102, which is beneficial to the circulating flow of the cooling liquid and the vapor, ensures the smooth flow of the cooling liquid and the gas, and avoids local overheating.

[0076] Specifically, the number of the communication holes 20 is multiple, and the multiple communication holes 20 include: a first communication hole 201 arranged on the top bent plate 21; and / or a second communication hole 202 arranged on at least one of the two side plates 22. By arranging the first communication hole 201 and the second communication hole 202, the present application can ensure that the cooling liquid and the steam can flow smoothly between the inner cavity 101 and the outer cavity 102, avoid local overheating, and improve the cooling efficiency. The implementation effect is that the flow of the cooling liquid and the steam is more uniform, the cooling effect is improved, and the consumption of the cooling liquid is reduced.

[0077] Preferably, the number of the first communication holes 201 is multiple, and the multiple first communication holes 201 are arranged on the top of the top bent plate 21. The number of the second communication holes 202 is multiple, and the multiple second communication holes 202 are arranged on at least one of the two side plates 22 in an array.

[0078] As shown in Figures 1 to 8 and Figure 10 , the number of the shell outlets is multiple, and the multiple shell outlets include a cooling liquid outlet 12 and a gas outlet 13. The cooling liquid outlet 12 and the gas outlet 13 are both in communication with the outer cavity 102. The cooling liquid outlet 12 is located below the gas outlet 13 to realize the separation of the cooling liquid and the steam, ensure that the cooling liquid can flow out smoothly through the cooling liquid outlet 12, and the steam can flow out through the gas outlet 13, avoid the mixing of the cooling liquid and the steam at the shell outlet, and improve the cooling efficiency.

[0079] As shown in Figures 1 to 8 and Figure 10 , the cooling assembly includes: a drain pipe 5 arranged at the cooling liquid outlet 12; and / or a second flow guide pipe 4 arranged at the gas outlet 13. By arranging the drain pipe 5 and the second flow guide pipe 4, the cooling assembly of the present application realizes the connection with the refrigerant flow pipeline outside the cooling assembly, ensures the efficient flow of the cooling liquid and the steam, ensures that the cooling liquid and the steam can flow out smoothly from the cooling assembly, and improves the cooling efficiency.

[0080] The cooling process of the cooling assembly of the present application is as follows:

[0081] (1) The low-temperature cooling liquid from outside the cooling assembly is introduced into the drain pipe 32 through the first flow guide pipe 31 of the cooling structure 3, and the cooling liquid is sprayed into the inner cavity 101 through the drain pipe 32. When the cooling liquid contacts and absorbs heat from the to-be-cooled component 1500 in the inner cavity 101, the temperature of the cooling liquid will rise. When the cooling liquid reaches its boiling point, it will begin to boil and transform into steam.
