Description

Technical Field

[0001] The present invention belongs to the technical field of data center equipment, and specifically relates to an immersed liquid-cooled cabinet for a data center. Background Art

[0002] With the continuous increase in the computing requirements of data centers, especially the rapid development of fields such as cloud computing, big data, and artificial intelligence, the demand for computing power and storage capacity in data centers continues to rise. Immersed liquid-cooling technology involves completely immersing electronic devices in a coolant, with the liquid directly absorbing the heat generated by the devices and removing the heat through a heat exchange system. This method is different from traditional air cooling. It can conduct heat more efficiently through the heat capacity and thermal conductivity of the liquid, and is particularly suitable for high-density and high-power-consuming devices. Immersed liquid cooling usually uses specific insulating liquids to ensure that no safety issues such as short circuits occur in the devices.

[0003] In an immersed liquid-cooling system, the liquid-cooled cabinet is one of the core components, enabling the devices to be immersed in the coolant while providing necessary electrical isolation and cooling circulation channels. Immersed liquid-cooled cabinets usually require special designs for sealing and heat exchange systems to ensure the circulation of the coolant and the effective removal of heat.

[0004] Traditional cabinets use rigid brackets to fix the host devices. For example, servers, storage devices, etc. are locked in the immersion tank through multiple groups of bolts or buckles. Although this design can ensure the stability of the devices, when maintaining, technicians need to wear protective equipment and directly reach into the coolant to perform hardware plugging or maintenance. For example, when replacing a faulty hard disk, at least 3 groups of fixed brackets need to be manually disassembled, and during the process, the coolant may seep into the unsealed interfaces, leading to a risk of short circuit.

[0005] Moreover, the existing heat dissipation architecture relies on the natural convection mode of "bottom liquid inlet - top liquid outlet". The flow path of the coolant is fixed and lacks forced driving. Taking a typical single-phase coolant (such as the 3M Novec series) as an example, its kinematic viscosity is relatively high. When driven only by gravity, the flow rate in the top device area is less than 30% of that in the bottom area, forming a significant temperature gradient. The temperature of the top devices in traditional cabinets can be 8 - 12 °C higher than that at the bottom, and the local hot spot temperature even exceeds the device junction temperature threshold. Therefore, it is necessary to improve and optimize it. Summary of the Invention

When maintenance or replacement of the main machine is required, the hydraulic press can accurately control the vertical movement of the bearing plate and the top cover, avoiding the complex operation of manual handling, significantly reducing the labor intensity and potential risks. The coordinated design of the sliding rod and the connecting rod mechanism ensures the stable and reliable lifting process. The limiting strip further prevents excessive displacement and improves the system safety.

The top cover effectively blocks the damage of environmental factors such as coolant splashing and dust intrusion to the main machine, and the bearing plate ensures uniform force when the equipment is completely immersed, avoiding hardware deformation or failure caused by excessive local pressure.

[0023] In the present invention, a power closed-loop is formed by the vertical circulation component and the horizontal circulation component through gear meshing, driving the coolant to flow three-dimensionally in a three-dimensional space. The design of four equally spaced fan blades optimizes the water flow path, eliminates heat dissipation dead corners, and cooperates with a circulation pump for forced convection, making the temperature distribution of the coolant more uniform and avoiding local overheating. The fan blade three of the heat dissipation component is integrated with the internal circulation system through a bevel gear three, forming an independent heat dissipation air duct outside the box body. When the coolant circulates to the outside through the hollow tube, the rotating fan blade three accelerates the air flow, not only reducing the return liquid temperature of the coolant, but also cooling the surface of the box body by air, forming a composite cooling mode of internal circulation heat dissipation + external air cooling assistance, significantly improving the heat exchange efficiency.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 8 shown, the present invention provides a data center immersion liquid-cooled cabinet, including a box body 1, and further including:

[0035] A lifting mechanism is arranged on the inner bottom wall of the box body 1 for facilitating the disassembly and assembly of the host;

[0036] A circulation mechanism is arranged on the box body 1 for accelerating the heat dissipation of the host;

[0037] Among them, the lifting mechanism includes a driving component fixedly installed on the inner wall of the box body 1 and two identical movable components fixedly installed on the inner walls of both sides of the bottom of the box body 1. The driving component is used to provide power to the two movable components. The movable component includes two slide rods 2 fixedly installed on the inner bottom wall of the box body 1. Moving plates 201 are slidably installed on the outer walls of the two slide rods 2. One end of each side of the moving plate 201 is hinged with a first connecting rod 2011. The other ends of the two first connecting rods 2011 are both hinged with a second connecting rod 2012. The bottom end of the second connecting rod 2012 is rotatably installed with a first rotating rod 2013. A first tooth column 2014 is fixedly sleeved on the outer wall of the first rotating rod 2013. The driving component includes a power component and a transmission component. The power component includes a hydraulic machine 3 fixedly installed on the inner wall of the box body 1. A toothed plate 301 is fixedly installed on the output shaft of the hydraulic machine 3. The tooth grooves of the toothed plate 301 are arranged downward for transmission with the transmission component. Two limiting strips 101 are fixedly installed inside the box body 1 for moving limit of the toothed plate 301. The two limiting strips 101 are respectively located on both sides of the toothed plate 301 and are both slidably connected with the toothed plate 301. The driving component includes a second tooth column 4 rotatably installed on the inner bottom wall of the box body 1. The top of the second tooth column 4 meshes with the toothed plate 301. The side surface of the second tooth column 4 meshes with the first tooth column 2014 for transmitting the power of the hydraulic machine 3 to the first tooth column 2014. A protection device is arranged on the top of the moving plate 201 in the two movable components. The protection device includes a bearing plate 202 fixedly installed on the tops of the two moving plates 201. A top cover 203 is fixedly installed on the top of the bearing plate 202.

[0038] Adopting the above solution: Through the design of the lifting mechanism, the convenient disassembly, assembly and maintenance of the host in the immersion liquid-cooled cabinet of the data center can be effectively realized. Specifically, the lifting mechanism provides power through the driving component to drive the operation of the hydraulic press 3. The power of the hydraulic press 3 is transmitted through the toothed plate 301 and the second toothed column 4, and finally drives the movement of the movable component. When it is necessary to repair, replace or adjust the position of the host, the host can be smoothly lifted and lowered through the hydraulic drive system, thereby reducing the complexity and potential risks of manual operation. The design of the slide bar 2 and the movable component ensures the smoothness and stability of the movement. At the same time, the setting of the limit bar 101 effectively prevents the excessive movement of the toothed plate 301, avoiding system damage or failure. This design also improves the efficiency of cabinet disassembly and assembly, greatly reduces the error of manual operation, improves the safety of system maintenance. At the same time, the protective device on the movable component, especially the design of the bearing plate 202 and the top cover 203, can effectively protect the host components from external impact or damage during the lifting process. The bearing plate 202 provides a stable support for the host, while the top cover 203 ensures the protection during the whole process, effectively avoiding the damage to the host caused by environmental factors such as liquid splashing, dust, etc. The addition of the circulation mechanism further accelerates the heat dissipation effect of the host and ensures the long-term stable operation of the system.

[0039] The circulation mechanism includes a circulation component A arranged inside the box body 1 and a circulation component B arranged on the outer wall of the box body 1. The circulation component B is used to provide power for the circulation component A. There are a total of four circulation components A, two in a group are respectively arranged on both sides of the power component. The circulation component A includes two vertical circulation components rotatably installed on the inner wall of the bottom of the box body 1 and two horizontal circulation components fixedly installed on the inner wall of the bottom of the box body 1: The vertical circulation component includes a second rotating rod 5 rotatably installed on the inner wall of the bottom of the box body 1. A first bevel gear 501 is fixedly sleeved on the outer wall of the bottom of the second rotating rod 5. A plurality of first fan blades 502 are fixedly arranged on the outer wall of the second rotating rod 5 above the first bevel gear 501. The four first fan blades 502 are evenly distributed in a group around the axis of the second rotating rod 5.

[0040] Adopting the above solution: By setting the circulation component A, power can be provided for the internal circulation component A, accelerating the circulation and heat dissipation of water. The main function of the vertical circulation component is to drive the first fan blades 502 to rotate by the rotation of the second rotating rod 5, so as to drive the transmission of the first bevel gear 501 through the flow of water, and the power can be efficiently transmitted from the vertical circulation component to the horizontal circulation component. The uniform distribution of the four first fan blades 502 in a group and the equidistant distribution help to optimize the uniformity of water flow, making the heat dissipation effect more balanced and efficient. Through the synergistic effect of the vertical circulation component and the horizontal circulation component, the whole system can operate stably, effectively improving the heat dissipation effect of the equipment.

[0041] The horizontal circulation component includes a fixed block 6 fixedly installed on the bottom inner wall of the box body 1 between two vertical circulation components. Rotating rods three 601 are respectively installed on the outer walls on both sides of the fixed block 6. Fixed sleeves of bevel gears two 602 are respectively sleeved on the ends of the two rotating rods three 601 away from the fixed block 6. The two bevel gears two 602 are respectively meshed with the bevel gears one 501 in the corresponding vertical circulation components. A number of fan blades two 603 are fixedly arranged on the outer walls of the two rotating rods three 601. Four of the fan blades two 603 are in a group and are evenly distributed around the axis of the rotating rod three 601.

[0042] Adopting the above scheme: By setting the fixed block 6, it plays a fixing role to ensure that the entire horizontal circulation component is firmly installed in the specified position and will not move due to external factors. The rotating rod three 601 is installed on the outer walls on both sides of the fixed block 6 and drives the rotation of other components through rotation to help achieve the effective delivery of air flow and heat dissipation effect. Through the meshing of the bevel gear two 602 on the rotating rod three 601 with the bevel gear one 501 in the vertical circulation component, the rotational power of the rotating rod three 601 is transmitted to the vertical circulation component to further realize the air flow and heat dissipation, which can effectively transmit power, reduce power loss at the same time, and improve the transmission efficiency. The setting of the fan blades two 603 fixed on the outer wall of the rotating rod three 601 plays a role in pushing the water flow. When the rotating rod three 601 rotates, the fan blades two 603 rotate accordingly, generating water flow and taking away heat. A number of fan blades two 603 are evenly distributed in a circular array at equal distances around the axis of the rotating rod three 601. This layout can optimize the distribution of air flow, ensure uniform flow and more efficient heat dissipation, and can improve the air flow circulation efficiency in the liquid cooling system. With the synergistic effect of the rotating rod three 601, the bevel gear system and the fan blades two 603, the cooling effect is optimized to avoid equipment failure caused by excessive temperature.

[0043] The circulation component B includes a flow control component fixedly installed on the outer wall of the box body 1 and four heat dissipation components arranged inside the wall of the box body 1. The flow control component includes a mounting frame 8 fixedly installed on the bottom outer wall of the box body 1. A circulation pump 801 is arranged on the top of the mounting frame 8. Hollow tubes 802 are respectively fixedly installed at the water outlet end and the water inlet end of the circulation pump 801. The other ends of the two hollow tubes 802 are fixedly connected to the outer wall of the box body 1 and are communicated with the inside of the box body 1. The heat dissipation component includes a rotating rod four 7 rotatably installed in the box body 1. The rotating rod four 7 penetrates the box body 1. A fixed sleeve of a bevel gear three 701 is sleeved on the outer wall of the rotating rod four 7 located inside the box body 1. The bevel gear three 701 is meshed with the bevel gear one 501 in the adjacent vertical circulation mechanism. A number of fan blades three 702 are fixedly arranged on the outer wall of the rotating rod four 7 located outside the box body 1. Four of the fan blades three 702 are in a group and are evenly distributed around the axis of the rotating rod four 7.

[0044] Adopt the above solution: The mounting bracket 8 provides support and ensures the secure installation of components such as the circulation pump 801 and the hollow tube 802. The function of the circulation pump 801 is to drive the flow of the coolant. The hollow tube 802 is connected through the water outlet end and the water inlet end to provide the necessary flow power. The two hollow tubes 802 are respectively connected to the water outlet end and the water inlet end of the circulation pump 801 and are fixedly connected to the outer wall of the box body 1. They transport the coolant into the box body 1 to ensure the smooth flow of liquid cooling. The heat dissipation component is mainly used to effectively dissipate heat through the contact between the air flow and the liquid. The rotation of the fan blade three 702 drives the air flow, increases the heat dissipation area, improves the heat dissipation efficiency, and ensures more efficient heat exchange and heat dissipation.

[0045] The working principle and usage process of the present invention:

[0046] First, fill the inside of the box body 1 with coolant, and then start the hydraulic press 3. The retraction of the output shaft of the hydraulic press 3 drives the fixedly installed toothed plate 301 to slide within the two limit strips 101. Through the meshing of the limit strip 101 with the second toothed column 4, the second toothed column 4 rotates. Through the meshing of the second toothed column 4 with the first toothed column 2014, the first toothed column 2014 and the first rotating rod 2013 are driven to rotate. The first rotating rod 2013 drives the two second connecting rods 2012 to rotate together. Through the articulated connection between the second connecting rod 2012 and the first connecting rod 2011, the rotation of the second connecting rod 2012 can drive the moving plate 201 at the top of the first connecting rod 2011 to extend and slide along the outer wall of the sliding rod 2 in the Y-axis direction. The two moving plates 201 together drive the bearing plate 202 and the top cover 203 on the top of the bearing plate 202 to move upward together, so that the bearing plate 202 and the top cover 203 are located above the box body 1;

[0047] Then, fixedly install the host device on the top of the bearing plate 202, and start the hydraulic press 3 again, so that the output shaft of the hydraulic press 3 moves in the reverse direction, and finally the bearing plate 202 and the top cover 203 move downward to the initial position, so that the host device is completely immersed in the coolant, and the coolant is used to cool the host device;

[0048] Since the heat generated inside the host device is uniform during use, in order to prevent insufficient local heat dissipation, the circulation pump 801 can be started to circulate and suction the coolant inside the box body 1 through two hollow tubes 802, so that the coolant inside it is always in a flowing state, avoiding local overheating. When the coolant inside the box body 1 flows inside the box body 1, the coolant can drive the fan blades 502 on the outer walls of the multiple second rotating rods 5 in the vertical circulation component to rotate. Through the rotation of the multiple fan blades 502, the second rotating rod 5 and the first upper bevel gear 501 on the outer wall of the bottom of the second rotating rod 5 are driven to rotate. Through the meshing of the bevel gear 501 with the bevel gear 602 and the bevel gear 701, the third rotating rod 601 can be driven to rotate first. Through the rotation of the fixed block 6, the multiple fan blades 603 fixedly installed on the outer wall of the third rotating rod 601 are driven to rotate, thereby increasing the flow rate of the coolant far from the two hollow tubes 802 and strengthening the absorption of the bottom heat in the host device;

[0049] At the same time, the rotation of the bevel gear 701 drives the fourth rotating rod 7 and the multiple fan blades 702 on the outer wall of the fourth rotating rod 7 to rotate. Since the multiple fan blades 702 are all located below the hollow tube 802, the rotation of the fan blades 702 forms a wind flow to physically cool the outer wall of the hollow tube 802 and reduce the temperature of the coolant inside it.
