Description

Technical Field

[0001] This invention relates to the field of server chassis structure, specifically to a server liquid-cooled and air-cooled hybrid heat dissipation chassis structure. Background Technology

[0002] With the development of technologies such as AI and cloud computing, server power density continues to rise. Traditional air-cooling systems can no longer meet the heat dissipation needs of high-performance servers, so liquid-cooled servers have emerged.

[0003] Liquid cooling versus air cooling: Liquid cooling advantages: its specific heat capacity is 25 times that of air, and its direct contact heat transfer efficiency is improved by more than 30%, making it especially suitable for high-power chips of 300W and above. Advantages of air cooling: easy to maintain, suitable for low-to-medium heat components such as memory and hard drives, and can utilize existing infrastructure.

[0004] Air-cooled systems have significantly reduced heat dissipation efficiency when the power of a single cabinet exceeds 15kW, while liquid cooling can handle high loads of 30kW or more, but the initial retrofit cost is too high.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0019] like Figures 1 to 6As shown, a server hybrid liquid-cooled and air-cooled heat dissipation chassis structure is disclosed. This chassis structure partitions air-cooling and liquid-cooling heat dissipation, and provides heat dissipation for high-power components of the server as needed, achieving a balanced and compatible solution for server heat dissipation requirements. Structurally, the chassis structure includes a chassis frame 1, with side panels hinged to its four sides. The side panels are secured to the chassis frame 1 with screws. (Protective plates are bolted to the top and bottom of the chassis frame 1 to protect the electronic components inside the chassis frame 1). The interior of the chassis frame 1 is divided into upper and lower layers by a mounting plate 11. The mounting plate 11 is connected to the chassis frame 1 by two vertically parallel support columns using screws. By dividing the chassis frame 1 into upper and lower layers using the mounting plate 11, it effectively partitions the chassis, with different areas on the upper and lower layers used to install server components of different power ratings. Meanwhile, liquid cooling plates are installed and connected to the bottom and top of the mounting plate 11; ventilation openings are provided on the mounting plate 11; a movable component is movably connected to the top of the mounting plate 11, and a movable plate 2 is installed and connected to the movable component, with a liquid cooling plate installed and connected to the movable plate 2; an air-cooling module is installed and connected above the movable plate 2 via a control component. All liquid cooling plates are connected to the liquid cooling pipes inside the server chassis structure, and the liquid cooling pipes are filled with coolant. The circulating coolant acts on the liquid cooling plates to achieve the purpose of heat dissipation. Based on the power rating of the electronic components on the server boards, server boards with different power ratings and containing electronic components are installed in the upper and lower compartments of the chassis frame 1. Liquid cooling plates and air-cooling modules then dissipate heat from these electronic components within the chassis frame 1. During use, the movement of the air-cooling module is adjusted according to the power rating, especially in areas with high power, where the air-cooling module is moved above that area. This allows for adjustment of either liquid cooling or air cooling, or both, for heat dissipation. Furthermore, the mounting plate 11 has ventilation openings for airflow from the air-cooling module, dissipating heat from the electronic components installed below and around the ventilation openings. This chassis structure design allows for the rational adjustment of liquid cooling and air cooling based on usage (power rating), achieving balanced heat dissipation and cost savings.

[0020] Furthermore, the chassis is designed with a dual-layer structure (such as a server rack or switch enclosure) to facilitate heat dissipation through the coordinated layout of liquid cooling modules (such as liquid cooling plates and liquid cooling circulation pipes) and air cooling modules (fans and air ducts). The liquid cooling system adopts a multi-stage piping design (such as water distributors and four-way pipes), combined with self-cleaning filters and pressure sensors, to reduce coolant contamination and maintenance downtime. The air cooling modules enhance airflow coverage, reduce noise, and prevent dust accumulation from affecting heat dissipation efficiency by optimizing the layout of air inlets and outlets (such as multi-fan walls and filters).

[0021] Furthermore, the movable component includes a movable slide plate 31; sliding guide rails are respectively provided on both sides of the bottom end of the movable slide plate 31, and the movable slide plate 31 is slidably set with the top end of the mounting plate 11 through the sliding guide rails, and the movable slide plate 31 is limitedly connected to the mounting plate 11 by screws. The movable plate 2 is movably set above the movable slide plate 31; a fixed side plate 32 is connected to one side of the movable slide plate 31 by screws; a mounting side plate 33 is provided on the other side of the movable slide plate 31, and the bottom end surface of the mounting side plate 33 is used for sliding and limiting contact with the top end surface of the movable slide plate 31; a movable support plate 34 is movably set between the fixed side plate 32 and the mounting side plate 33; the movable plate 2 is used for movably installed and connected to the mounting side plate 33 and the movable support plate 34 (according to the design, the movable plate 2 is movably installed between the mounting side plate 33 and the movable support plate 34 and at the top of the two). The movable slide plate 31 is connected to the top of the mounting plate 11, which is mounted on the chassis frame 1, via a sliding guide rail. After adjusting the position of the movable slide plate 31 and the mounting plate 11, the movable slide plate 31 and the mounting plate 11 are fixed together with screws to prevent movement. In the area below the movable slide plate 31 on the mounting plate 11, the circuit boards for high-power server components are installed to facilitate heat dissipation through a combination of liquid cooling and air cooling.

[0022] Furthermore, an adjusting screw 35 is provided between the mounting side plate 33 and the fixed side plate 32. One end of the adjusting screw 35 is rotatably connected to the movable support plate 34 between the mounting side plate 33 and the fixed side plate 32 via a screw nut, and its end is rotatably connected to the fixed side plate 32 via a bearing. The other end of the adjusting screw 35 is rotatably connected to the mounting side plate 33 via a bearing, and its end is connected to the adjusting handwheel 351. Rotating the adjusting handwheel 351 drives the adjusting screw 35 to rotate. At the same time, movable guide rods 36 are provided on both sides of the adjusting screw 35. One end of the movable guide rod 36 is connected to the mounting side plate 33 for limiting connection, and the other end of the movable guide rod 36 is rotatably connected to the movable support plate 34 and its end is rotatably connected to the fixed side plate 32. The bottom ends of the mounting side plate 33 and the movable support plate 34 are connected by a connecting block, connecting the mounting side plate 33 and the movable support plate 34 into a single unit. During installation, by adjusting the rotating handwheel 351, the adjusting screw 35 is rotated. The rotating screw 35 moves and, under the guidance of the movable guide rod 36, moves the mounting side plate 33 and the movable support plate 34 together, thereby adjusting the position of the movable plate 2 set between the mounting side plate 33 and the movable support plate 34, as well as the position of the electronic components mounted on the circuit board on the movable plate 2.

[0023] Furthermore, the end of the mounting side plate 33 near the fixed side plate 32 (or, possibly, near the movable support plate 34) is connected to an active transmission assembly; the active transmission assembly includes an active upper transmission wheel a331, an active upper transmission wheel b332, an active drive wheel 333, and two active receiving and limiting wheels 334; the active upper transmission wheel a331 is rotatably mounted on one side of the top of the mounting side plate 33 via a rotating shaft, and the active upper transmission wheel b332 is rotatably mounted on the other side of the top of the mounting side plate 33 via a rotating shaft; the active drive wheel 333 is located at the bottom of the side of the mounting side plate 33 near the fixed side plate 32 (or, possibly, near the movable support plate 34), and rotates via a drive shaft 336. The drive shaft 336 passes through the mounting side plate 33, and its end is connected to the output end of the control servo 335 via a shaft connector. The control servo 335 is used to connect and fix to the mounting side plate 33. The other end of the drive shaft 336 passes through the movable support plate 34 via a bearing and its end is used to connect to the fixed side plate 32. Two active bearing limit wheels 334 are arranged between the active upper transmission wheel a331 and the active drive wheel 333 (the two active bearing limit wheels 334 are arranged between the active upper transmission wheel a331 and the active drive wheel 333 in the vertical direction). The active upper transmission wheel a331, the active upper transmission wheel b332, the active drive wheel 333, and the two active bearing limit wheels 334 are connected by belt drive.

[0024] Meanwhile, a passive transmission assembly is connected to one end of the movable support plate 34 near the mounting side plate 33; the passive transmission assembly includes a passive upper transmission wheel a341, a passive upper transmission wheel b342, a passive drive wheel 343, and two passive receiving and limiting wheels 344; the passive upper transmission wheel a341 is rotatably connected to one side of the top of the movable support plate 34 (the top side of the movable support plate 34 near the mounting side plate 33, which is rotatably arranged relative to the active upper transmission wheel a331) via a rotating shaft, and the passive upper transmission wheel b332 is rotatably connected to the other side of the top of the movable support plate 34 (which is rotatably arranged relative to the active upper transmission wheel b332) via a rotating shaft. (Settings); The passive drive wheel 343 is located at the bottom of the movable support plate 34 near the mounting side plate 33, and is connected to the drive shaft 336 (the passive drive wheel 343 is connected to the drive shaft 336 and is set opposite to the active drive wheel 333); Two passive bearing limit wheels 344 are set between the passive upper transmission wheel a3 and the passive drive wheel (the two passive bearing limit wheels 344 are set between the passive upper transmission wheel a341 and the passive drive wheel 343 in the vertical direction); The passive upper transmission wheel a341, the passive upper transmission wheel b342, the passive drive wheel 343, and the two passive bearing limit wheels 344 are connected by belt drive.

[0025] Furthermore, one end of the movable plate 2 is connected to the upper surface of the belt that drives the upper drive wheel a331 and the upper drive wheel b332 via a limiting buckle, and the movable plate moves via the belt that drives the upper drive wheel a331 and the upper drive wheel b332; the other end of the movable plate 2 is connected to the upper surface of the belt that drives the upper drive wheel a341 and the upper drive wheel b342 via a limiting buckle, and the movable plate 2 moves via the belt that drives the upper drive wheel a341 and the upper drive wheel b342.

[0026] In this embodiment, the drive shaft 336 is rotated by the control servo motor 335. The drive shaft 336 drives the active drive wheel 333 and the passive drive wheel 343 to rotate together with the drive shaft 336. Thus, the active drive wheel 333, through the belt connected to the transmission mount, drives the active upper transmission wheel a331 and active upper transmission wheel b332 to rotate under the transmission action of the two active bearing limit wheels 334. Ultimately, the belt on the mounting side plate 33 drives the movable plate 2 connected to the belt to move horizontally back and forth. At the same time, the passive drive wheel 343, through the belt connected to the transmission mount, drives the passive upper transmission wheel a341 and passive upper transmission wheel b342 to rotate under the transmission action of the two passive bearing limit wheels 344. Ultimately, the belt on the movable support plate 34 drives the movable plate 2 connected to the belt to move horizontally back and forth. Since both the active drive wheel 333 and the passive drive wheel 343 are mounted on the drive shaft 336, rotating the drive shaft 336 can drive the active drive wheel 333 and the passive drive wheel 343 to rotate synchronously (in the same direction). Finally, by controlling the servo motor 335, the movable plate 2 and the electronic component circuit board mounted on the movable plate 2 can be moved back and forth to achieve position adjustment.

[0027] When the server is used, the electronic components installed inside the chassis structure are allowed to generate heat; in order to dissipate heat from the electronic components inside the chassis structure, the liquid cooling system and air cooling system installed inside the chassis structure are activated to dissipate heat. Because the electronic components installed in the various control parts inside the server chassis have different power ratings, and the power ratings are respectively installed in different areas of the upper and lower layers inside the chassis structure (chassis frame 1); in this patent embodiment, the circuit board of the high-power electronic component is installed in the lower middle position of the mounting plate 11, and the circuit board of the low-power electronic component is installed in the ventilation position below the mounting plate 11; in this way, by adjusting and controlling the horizontal movement of the air-cooling module at the top of the chassis structure, the air-cooling module can dissipate "heat dissipation air" through the ventilation port to dissipate heat from the low-power electronic components below; and the air-cooling module can move horizontally "back and forth" at the top of the chassis structure, which can cooperate with the liquid cooling module on the movable plate 2 and the mounting plate 11 to perform "liquid-cooled and air-cooled hybrid heat dissipation" for the high-power electronic components installed on the movable plate 2 and the mounting plate 11, achieving both balanced heat dissipation and cost savings, achieving two goals at once. Furthermore, in this embodiment, a displacement sensor is installed and connected on the movable plate 2; a displacement sensor is installed and connected to the top of the mounting side plate 33; and a displacement sensor is installed and connected to the top of the movable support plate 34. This allows for feedback and detection of the position of the "moving components and control components," enabling the convenient achievement of a balance between optimal "liquid cooling and air cooling hybrid heat dissipation."

[0028] Furthermore, the control components of this setup include a first movable electric guide rail 41 and a second movable electric guide rail 42. A fixed connecting plate is horizontally and movably connected to the first movable electric guide rail 41, and a displacement sensor is installed on the fixed connecting plate. The fixed connecting plate is used to connect to the air-cooling module, and the air-cooling module moves horizontally via the first movable electric guide rail 41. The top end of the first movable electric guide rail 41 is used to slide horizontally with the second movable electric guide rail 42, and the first movable electric guide rail 41 and the second movable electric guide rail 42 are arranged perpendicularly to each other. The top end of the second movable electric guide rail 42 is horizontally slidably connected to the top end of the chassis frame 1 via a sliding guide beam. This design allows the air-cooling module to perform "all-round" heat dissipation on the electronic components inside the chassis frame 1 by controlling the "front-back displacement" of the air-cooling module through the first movable electric guide rail 41 and the "left-right displacement" of the air-cooling module through the second movable electric guide rail 42.
