Description

Technical Field

[0001] This utility model belongs to the field of communication equipment technology, and in particular relates to a high-efficiency fully immersed liquid-cooled computing cube and data center heat dissipation system. Background Technology

[0002] In today's digital wave, data centers and intelligent computing centers serve as core hubs, with their scale and computing power continuously expanding. With the rapid development of cutting-edge technologies such as artificial intelligence and big data analysis, the demand for data processing is growing exponentially, causing the power density of equipment in data centers to rise sharply. As a result, fully immersed liquid-cooled servers and data centers have emerged. At the same time, in order to improve the efficiency of data center construction and flexible layout, mobile integrated immersion liquid-cooled servers are gradually gaining market recognition.

[0003] Existing technology 1: Patent No.: CN119225494A, Immersion Server. This technology involves immersing the server in coolant and using structural design to address the issue of uneven cooling.

[0004] Prior Art 2: Patent No.: CN119767648A, an immersion liquid-cooled server rack structure. By configuring liquid cooling components, monitoring components, and control components, servers with high heat dissipation can be separated. The coolant in the separated areas circulates for cooling, resulting in low energy consumption and ensuring effective heat dissipation for the servers. Simultaneously, it avoids affecting other servers, thereby improving the overall performance of the equipment.

[0005] The aforementioned existing technologies can effectively solve the problems of server overheating, flexible deployment, and long data center construction cycles. However, due to the lack of corresponding airflow design, the heat generated by current all-in-one liquid-cooled servers is absorbed by the coolant and eventually accumulates in the heat dissipation area and spreads outwards. This causes the temperature of the liquid-cooled server's air inlet and outlet to rise, increasing the power consumption of the heat dissipation system and affecting the large-scale deployment of all-in-one immersion liquid-cooled servers. At the same time, since the heat cannot be effectively dissipated, sufficient air inlet and outlet space must be left between all-in-one immersion servers, which also reduces the computing power density of the data center. Utility Model Content

[0006] This invention addresses the shortcomings of existing technologies that lack effective solutions for heat generated by immersion liquid cooling, resulting in heat accumulation around the equipment, increased power consumption of the cooling system, and hindering the long-term reliable operation of integrated immersion liquid-cooled servers and data centers. Furthermore, the requirement for sufficient space at air inlets and outlets reduces the effective usable area of ​​the entire data center and limits the unit computing power density. This invention provides a highly efficient fully immersion liquid-cooled computing cube and data center cooling system.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency fully immersion liquid-cooled computing cube and data center heat dissipation system, comprising multiple heat dissipation system cabinets, an air inlet on the front surface of each heat dissipation system cabinet, an air outlet on the upper surface of each heat dissipation system cabinet, an arc-shaped air guide plate inside each heat dissipation system cabinet, a dry cooler inside each heat dissipation system cabinet at the air inlet, and a cooperating exhaust mechanism above each heat dissipation system cabinet for exhausting and cooling the heat dissipation system cabinet.

[0008] Optionally, the exhaust mechanism includes an exhaust duct installed above the heat dissipation system cabinet, the bottom of the exhaust duct is connected to a heat absorption air outlet corresponding to the air outlet, and an exhaust fan is installed at one end of the exhaust duct.

[0009] Optionally, the cooling system cabinet is provided with a server immersion zone inside.

[0010] Optionally, a reinforcing hoop is fixedly installed in the middle of the inner cavity of the heat absorption air inlet, and a sound-absorbing plate is fixedly installed on the inner surface of the reinforcing hoop.

[0011] Optionally, a rotating shaft is fixedly installed in the middle of the inner cavity of the heat absorption air outlet above the reinforcing hoop, and an arc-shaped plate is rotatably installed on the surface of the rotating shaft.

[0012] Optionally, a damping block is fixedly installed on the inner surface of the heat absorption air outlet, and a spring is fixedly installed between one side of the damping block and the arc-shaped plate.

[0013] Optionally, sound insulation cotton is fixedly installed on the lower surface of the inner cavity of the exhaust duct.

[0014] Optionally, the bottom of the heat dissipation system cabinet is equipped with casters.

[0015] In summary, compared with existing technologies, the beneficial effects of this solution are as follows: (1) This utility model breaks away from the traditional side-in and side-out design by designing the exhaust duct. It adopts a novel duct structure design with rear-in and top-out plus a guide plate, which realizes the rapid transfer of the server's power consumption heat to the top exhaust vent, avoiding the long-term accumulation of heat in the server heat dissipation system cabinet area and the surrounding equipment. At the same time, it also avoids the heat from spreading to the tank box area. The multi-vent heat dissipation duct design accurately and quickly transfers the heat accumulated at the top vent of each server, greatly reducing the temperature rise of the data center, thereby reducing the power consumption of the server and data center heat dissipation system and achieving energy-saving effect. (2) This utility model is different from the traditional integrated immersion liquid-cooled server. The traditional server air duct structure is side air intake and exhaust. In the actual layout of the data center, it is necessary to consider leaving enough air intake and exhaust space on both sides of the immersion liquid-cooled server to ensure air volume and heat dissipation effect. However, the novel air duct structure of rear air intake, air guide plate and top air exhaust in this design can realize the side layout of immersion liquid-cooled servers. The side does not need to occupy space. Only a distance needs to be left at the rear air intake. Under the premise of ensuring flexible deployment, the computing power density of the data center is greatly improved.

[0016] (3) This utility model, through the setting of sound-absorbing plate, rotating shaft, arc plate and sound insulation cotton, can buffer and reduce the gas flow rate during the exhaust heat dissipation and air intake, and avoid the high-speed airflow from impacting the air duct. It can effectively reduce wind noise, create a quiet working environment, and ensure the comfort of the operator. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] refer to Figure 1A high-efficiency fully immersion liquid-cooled computing cube and data center heat dissipation system includes multiple heat dissipation system cabinets 10. The bottom of each heat dissipation system cabinet 10 is equipped with casters 11 for easy movement. The interior of each heat dissipation system cabinet 10 is equipped with a server immersion area 16 for fully immersing the server in coolant.

[0021] Further reference Figure 1 , Figure 2 and Figure 3 The heat dissipation system cabinet 10 has an air inlet 12 on its front surface and an air outlet 13 on its upper surface. The heat dissipation system cabinet 10 has an arc-shaped air guide plate 15 inside, and a dry cooler 14 is installed inside the heat dissipation system cabinet 10 on one side of the air inlet 12. When in use, cold air flows into the dry cooler 14 from the air inlet 12. After heat exchange, the air is guided by the air guide plate 15 to the air outlet 13. The air guide plate 15 can prevent heat from spreading to the TANK box. The entire structural design can realize the rapid transfer of heat and avoid the accumulation of heat around the equipment, thereby increasing the power consumption of the server and data center heat dissipation system and improving the unit computing power density. At the same time, the air duct design is very simple and also greatly reduces the difficulty of production assembly and later maintenance.

[0022] Furthermore, thanks to the aforementioned special airflow structure design, the integrated immersion server cluster can be tightly arranged without considering the need to maintain a certain distance between two devices for air intake, maximizing the use of data center space and achieving high computing density deployment of the entire data center.

[0023] Further reference Figure 1 The cooling system cabinet 10 is equipped with an exhaust duct 17 at the top, and the bottom of the exhaust duct 17 is connected to a heat absorption vent 18 that corresponds one-to-one with the air outlet 13. This ensures that the heat generated by the server's heat consumption is discharged from the data center in a timely manner, reducing the overall temperature of the data center and thus reducing the power consumption of the server and the data center cooling system, achieving the purpose of energy saving. In addition, an exhaust fan 19 is installed at one end of the exhaust duct 17. When in use, the hot air after heat exchange is quickly transferred to the upper air outlet. After the heat accumulates at the upper air outlet, the exhaust fan 19 works to accurately transfer the heat accumulated at the air outlet 13 through the heat absorption vent 18, avoiding the long-term accumulation of heat around the integrated liquid-cooled server. If the heat cannot be dissipated quickly, it will lead to an increase in the server's heat dissipation power consumption. In addition, the temperature accumulation will also lead to an increase in the power consumption of the entire data center cooling system, thereby achieving the energy saving effect.

[0024] Further reference Figure 4 , Figure 4 and Figure 6A reinforcing hoop 20 is fixedly installed in the middle of the inner cavity of the heat absorption air outlet 18. The reinforcing hoop 20 can prevent the heat absorption air outlet 18 from deforming or collapsing under negative pressure, thus improving its service life. A sound-absorbing plate 21 is fixedly installed on the inner surface of the reinforcing hoop 20, which effectively absorbs wind noise. The sound-absorbing holes of the sound-absorbing plate 21 are honeycomb-shaped, which increases the sound wave reflection path and improves the sound absorption efficiency.

[0025] Further reference Figure 6 A rotating shaft 22 is fixedly installed above the center of the inner cavity of the heat absorption air outlet 18. An arc-shaped plate 23 is rotatably installed on the surface of the rotating shaft 22. A damping block 24 is fixedly installed on one side of the inner cavity of the heat absorption air outlet 18. A spring 25 is fixedly installed between one side of the damping block 24 and the arc-shaped plate 23. When the air is being drawn out for heat dissipation, the hot air impacts the arc-shaped plate 23, causing the arc-shaped plate 23 to rotate. The arc shape guides the hot air, preventing the hot air from directly impacting the exhaust fan 19 and reducing noise generation. The rotation of the arc-shaped plate 23, through the cooperation of the damping block 24 and the spring 25, can buffer and dampen the arc-shaped plate 23, further reducing noise generation, improving the noise reduction effect, and ensuring the comfort of the surrounding working environment.

[0026] Further reference Figure 5 and Figure 7 The lower surface of the inner cavity of the exhaust duct 17 is fixedly installed with sound insulation cotton 26 to further prevent the airflow after diversion from impacting the exhaust duct 17 and generating noise, effectively improving the noise reduction effect and creating a quiet working environment.

[0027] Working principle: In practical applications, the selection of fan 19 and dry cooler 14 is first determined based on the server's heat dissipation and power consumption. The structure of fan 19 and dry cooler 14 is adapted to the integrated immersion liquid-cooled server heat dissipation system cabinet area. With the help of the air guide plate 15 structure, the hot air after heat exchange is guided to be quickly transferred to the upper air outlet 13. After the heat is accumulated at the upper air outlet 13, it is discharged from the data center through the specially designed data center heat dissipation system air duct, realizing the rapid transfer of heat and avoiding the long-term accumulation of heat around the integrated liquid-cooled server.

[0028] Finally, it should be noted that the connection and fixing of each component of this utility model's high-efficiency fully immersed liquid-cooled computing cube and data center heat dissipation system can be achieved using conventional mechanical connection structures. The control system and connection methods required between multiple electrical components and drive components can also be achieved using conventional means and can be equipped with corresponding sensors and detectors. As long as the beneficial effects or the specific actions during the above-mentioned work can be achieved, it can be implemented.
