Description

Technical Field

[0001] This invention belongs to the field of data center liquid cooling operation and maintenance technology, specifically relating to an integrated operation and maintenance vehicle for immersion liquid cooling. Background Technology

[0002] With the rapid increase in chip computing power, the demands for chip power consumption and heat dissipation are also growing, making liquid cooling systems the primary choice for next-generation data center cooling systems. Immersion liquid cooling, where server electrical components and chips are completely submerged in the cooling medium, allows all heat to be carried away, significantly improving heat exchange efficiency. It also eliminates the need for additional air-cooled cooling equipment for other components, making it increasingly accepted by industry customers. However, while immersion liquid cooling offers excellent cooling performance, the absence of fans in liquid-cooled servers necessitates either power-off operation or placement in a relatively cool environment, such as a dedicated maintenance room or a dedicated cooling liquid, during maintenance. Otherwise, the server risks overheating and crashing due to high power consumption without proper cooling. This presents significant inconvenience for server maintenance. Summary of the Invention

Obviously, the following description of the structure of the accompanying drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.

[0020] Example:

[0021] like Figure 1 and Figure 2As shown, this embodiment provides an integrated maintenance vehicle for immersion liquid cooling, including a server 1, a vehicle frame 2, and a liquid storage tank 3, a compressor 4, and an air supply box 5, all mounted on the upper part of the vehicle frame 2, facilitating overall movement. The outlet of the compressor 4 is connected to the inlet of the air supply box 5, used to generate cooling air through the compressor 4 and send it into the air supply box 5, facilitating the guidance of the cooling air through the air supply box 5 and better blowing it onto the server 1. The upper end of the liquid storage tank 3 is provided with an operating platform, which is an inclined surface whose height gradually increases from one side to the other in the horizontal direction. The upper part of the air supply box 5 is located on the other side of the operating platform, and the upper part of the air supply box 5 is provided with an air outlet 501 that blows cooling air onto the operating platform. When the server 1 is placed on the operating platform, the cooling air delivered by the air outlet 501 can just blow onto the server 1, cooling the server 1, thereby reducing the wear and tear on the server 1 and ensuring the server's performance. Stable operation of 1; A coolant return zone is provided on one side of the operating table. The inner bottom surface of the coolant return zone is provided with a storage tank inlet that connects to the inside of the storage tank 3. A perforated limiting plate 6 is provided on the side of the coolant return zone near the server 1. The server 1 is located in the middle of the operating table and supported on the perforated limiting plate 6. The perforated limiting plate 6 not only supports the server 1 and prevents it from sliding down, but also allows the coolant flowing out of the opening of the server 1 to flow into the coolant return zone through the hole on the perforated limiting plate 6, and then into the storage tank 3 through the storage tank inlet, realizing the recovery of coolant. Preferably, the opening from which the coolant flows out of the server 1 is oriented towards the perforated limiting plate 6. A drain port 301 is provided at the lower part of the storage tank 3. A valve is installed at the drain port 301 to control its discharge, so that the coolant in the storage tank 3 can be taken out and used for subsequent system replenishment, reducing coolant waste and saving operation and maintenance costs.

[0022] It should be noted that, preferably, the operating table is recessed above the liquid storage tank 3, meaning that the operating table is surrounded by protective structures for the server 1, such as... Figure 1 As shown, for example, the two sides of the operating table are a perforated limiting plate 6 and an air supply box 5 that can protect the server 1. Both ends of the operating table are equipped with baffles. The height of the perforated limiting plate 6, the air supply box 5 and the two baffles are all higher than the operating table, thus providing a limiting protection effect for the server 1 on the operating table.

[0023] It should be further noted that, preferably, the liquid storage tank 3 is a sealed box made of welded stainless steel, which ensures its service life and will not contaminate the coolant.

[0024] It should be further explained that the valve installed at the drain port 301 can be an electric valve, a manual valve, or even a sealing cap; this embodiment does not impose any specific restrictions.

[0025] This invention mounts all equipment onto the vehicle frame 2 for easy overall movement. The compressor 4 can produce low-temperature cold air at different temperatures, adjusting the airflow temperature and volume according to the server 1's power consumption and maintenance duration. This air is then blown onto the server 1 through the air supply box 5 to cool it down, ensuring operational safety and stability while minimizing power consumption. Due to the inclined operating platform, coolant flowing from the server 1 can pass through the holes in the perforated limiting plate 6 into the coolant return area, and then flow into the storage tank 3 through the inlet, achieving coolant recovery and preventing waste. The recovered coolant can also be used for subsequent system replenishment, further reducing waste and saving maintenance costs. Furthermore, the server 1 is effectively supported on the operating platform by the perforated limiting plate 6, ensuring its stability and enabling online maintenance and repair.

[0026] As a preferred embodiment of this invention, it should be further explained that an air supply plate perpendicular to the operating table is provided on the upper part of the air supply box 5 near the operating table. Multiple air outlets 501 are evenly distributed on the air supply plate, so that the air coming out of the air outlets 501 can be directly blown onto the server 1 placed on the operating table, thereby improving the cooling effect of the cooling air on the server 1 and reducing the waste of resources.

[0027] As a preferred embodiment of this example, it should be further noted that the lower part of the liquid storage tank 3 is provided with an equipment clearance opening for easy installation of equipment. The compressor 4 is installed on the vehicle frame 2 at the equipment clearance opening. This can ensure the stability of the compressor 4 without affecting the stability of the liquid storage tank 3. It should be noted that the internal space of the liquid storage tank 3 can be arranged according to the actual situation to facilitate the collection of the recovered coolant to the drain port 301.

[0028] As a preferred embodiment of this invention, it should be further noted that the lower end of the vehicle frame 2 is equipped with walking wheels 201 controlled by a walking motor. This can be achieved using existing technology, which is relatively mature, and the implementation method is not specifically limited in this embodiment. The front end of the vehicle frame 2 is provided with a control lever 202 for controlling the operation of the walking motor. For example, under the control of the control lever 202, the vehicle frame 2 can be driven to move forward, backward, turn, and brake, improving convenience. This allows the device to be quickly deployed to the vicinity of the designated liquid-cooled server tank under single-person operation, without the need for manpower, and is easy to operate. The vehicle frame 2 is also equipped with a battery 14 to power the control lever 202 and the walking motor, ensuring the normal operation of the equipment. It should be noted that the battery 14 in this embodiment can directly power the operation of the electronic equipment on the entire integrated immersion liquid-cooled maintenance vehicle, ensuring the normal operation of the equipment when no external power source is connected. Of course, other electronic equipment can also be equipped with batteries for power supply separately, and this embodiment does not impose specific limitations.

[0029] As a preferred embodiment of this example, it should be further explained that the drain port 301 is a drain pipe that extends to the lower end of the vehicle frame 2. The valve is installed on the drain pipe, which can better drain all the coolant in the reservoir 3. The wheels 201 can raise the height of the vehicle frame 2, thereby ensuring that there is enough space at the lower end of the vehicle frame 2 to install the drain pipe.

[0030] As a preferred embodiment of this invention, it should be further explained that a lifting device is also installed on the vehicle frame 2. The lifting device includes a column 7, a boom 8, and a lifting device 9. The lifting device 9 is located above the liquid storage tank 3 and may include a steel wire and a hook. The hook is connected to the boom 8 through the steel wire. The hook can lift heavy objects to facilitate the lifting of the server 1 for maintenance, etc. The lower end of the column 7 is rotatably connected to the vehicle frame 2, which facilitates rotation and displacement during lifting. The boom 8 is a telescopic rod structure. One end of the boom 8 is hinged to the top of the column 7. The lifting device 9 is installed at the other end of the boom 8, which can adjust the length and height of the boom 8 to better lift the server 1.

[0031] As a preferred embodiment of this work, it should be further explained that the hoisting equipment also includes a control console 10 and a first electric telescopic rod 11 and a second electric telescopic rod 12 electrically connected to the control console 10. One end of the first electric telescopic rod 11 is rotatably connected to the column 7, and the other end of the first electric telescopic rod 11 is rotatably connected to one end of the boom 8. Both ends of the second electric telescopic rod 12 are rotatably connected to both ends of the boom 8, respectively. By controlling the first electric telescopic rod 11 and the second electric telescopic rod 12 through the control console 10, the boom 8 can be adjusted, thereby making the entire hoisting process easier. It should be noted that the control console 10 is a controller, which can be equipped with some control buttons and / or control handles to make control easier.

[0032] As a preferred embodiment of this invention, it should be further explained that the hoisting equipment also includes a base 13 installed on the vehicle frame 2. The lower end of the column 7 extends into the base 13 and is rotatably connected to the base 13 through a slewing drive mechanism. The slewing drive mechanism is located inside the base 13 and is electrically connected to the control console 10. The entire operation of the hoisting equipment can be controlled through the control console 10, which further improves the convenience of the entire hoisting process.

[0033] As a preferred embodiment of this invention, it should be further explained that the rotary drive mechanism includes a rotary motor, a drive gear, and an inner ring and an outer ring rotatably connected. The rotary motor is electrically connected to the control console 10. The lower part of the column 7 is rotatably connected to the base 13. The inner ring is connected to the lower end of the column 7, so that the inner ring and the column 7 maintain a synchronous rotational relationship. The outer ring is connected to the base 13 or the vehicle frame 2 to achieve the positioning of the outer ring. The rotary motor is mounted on the column 7, and the drive gear is mounted on the motor shaft of the rotary motor. The drive gear meshes with the outer ring. When the rotary motor starts, it drives the drive gear to rotate. The drive gear rotates along the outer ring with the cooperation of the outer ring, thereby driving the rotary motor to rotate along the outer ring, and synchronously driving the column 7 to rotate. The structure is simple and practical, and has good stability.

[0034] As a preferred embodiment of this invention, it should be further noted that the compressor 4 is a variable frequency compressor that facilitates the adjustment of the air supply temperature and air supply speed, and is suitable for various working conditions.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
