[0002] Overheating of components in servers is one of the most common reasons for product failure. Traditional servers are often equipped with multiple sets of fan modules to accelerate heat convection to exchange electronic components and reduce the temperature of the server. In the prior art, larger and higher-powered fans or increasing the number of fans can be used to improve heat dissipation efficiency. However, when the number of fans increases or the power increases, it will occupy the space for setting up electronic components inside the server and even generate more noise. Therefore, it is necessary to strengthen the heat dissipation technology to meet the heat dissipation needs of the server.
[0003] At present, the immersion liquid cooling solution in the data center generally adopts a cabinet structure, uses an insulating coolant, and exchanges heat with an external plate heat exchanger through a water pump circulation. The other end of the plate heat exchanger has an outdoor cooling tower or chiller to provide cooling capacity, and finally realizes the step-by-step transfer of heat and discharges it to the outside. This solution has the following disadvantages:
[0004] The coolant adopts an up-and-down diagonal flow field in the box, and the inlet flow distribution of the server node is uneven, which makes it easy for some server nodes to overheat.
[0005] The entire chassis cannot flexibly select server nodes that adapt to different loads and working conditions, and disassembly and installation are complicated.
[0006] In summary, how to effectively solve the problems of low heat exchange efficiency, uneven flow distribution and inability to match different load requirements of servers is an issue that technical personnel in this field urgently need to solve. Utility Model Content

[0025] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0027] To facilitate understanding of the present invention, the server cluster immersion magnetic fluid cooling device provided by the present invention is further described below based on the working principle of the server cluster immersion magnetic fluid cooling device of the present invention in combination with the embodiments.
[0028] For details, please refer to Figure 1 , the server cluster immersion magnetic fluid cooling device comprises:
[0029] A sealed immersion tank, wherein a plurality of servers are placed in the immersion tank; the immersion tank is filled with magnetic fluid; interfaces are provided at both end faces of the immersion tank, and the interfaces at the two end faces of the immersion tank are respectively connected to the two ends of a circulation pipe 4; an integrated magnetic field generator 3 is arranged around the immersion tank, and the integrated magnetic field generator 3 provides a magnetic field for the immersion tank, and the magnetic field provides flow power for the magnetic fluid in the immersion tank.
[0030] Specifically, the immersion tank is large enough to accommodate the entire server cluster. Ensure that the tank material is compatible with the magnetic fluid and has good sealing properties to avoid contamination by external media. Therefore, a stainless steel sealed box 1 is selected as the immersion tank.
[0031] The side of the stainless steel sealed box 1 is provided with an opening, the bottom of the opening is connected to a track, the track is laid on the bottom surface of the stainless steel sealed box 1, and the track is movably connected to the server carrying drawer 2 through a sliding member, and the server carrying drawer 2 is used to carry the server; the server carrying drawer 2 is provided with a baffle matching the opening, and the baffle blocks the opening when the server carrying drawer 2 is located inside the stainless steel sealed box 1. In this way, the server can be freely loaded and unloaded. For example, when a server needs to be repaired, the magnetic fluid is stopped from flowing, and the server carrying drawer 2 is pulled out to take out the server.
[0032] In order to avoid magnetic fluid leakage caused when taking out the server, the server carrying drawer 2 includes a base, a first baffle and a second baffle. The first baffle is arranged at the front end of the base, and the first baffle blocks the opening when the base is outside the stainless steel sealed box 1; the second baffle is arranged at the rear end of the base, and the second baffle blocks the opening when the base is inside the stainless steel sealed box 1; the second baffle is provided with a wiring hole, and a plastic ring is provided on the wiring hole, and the plastic ring blocks the gap between the wire and the wiring hole. The edges of the second baffle and the second baffle are both provided with sealing strips matching the edges of the opening. The top of the stainless steel sealed box 1 is provided with a long hole opposite to the two side edges of the base, and the long hole is used to insert a partition plate for partition sealing; a one-way sealing rubber strip is provided on the long hole. When taking out the server, the partition plate is first inserted from the corresponding two long holes. The partition plate isolates the drawer area from other areas of the stainless steel sealed box 1. When pulling out the drawer, only a small amount of magnetic fluid will be taken out, so that the leakage loss of magnetic fluid can be minimized when pulling out the drawer.
[0033] The server chassis includes through holes for the magnetic fluid to pass through. For example, the chassis is provided with a plurality of metal grids on the side through which the magnetic fluid passes.
[0034] Oily magnetic fluid is used as the magnetic fluid to avoid corrosion to server components.
[0035] The integrated magnetic field generator 3 is located around or at the bottom of the immersion tank. This generator can generate an adjustable magnetic field to produce the desired effect on the magnetic fluid and achieve precise control of the fluid. In addition, the integrated magnetic field generator 3 can be used in conjunction with a magnetic field regulator, which monitors the temperature distribution and load conditions of the server cluster in real time. According to the monitoring data, the intensity and direction of the magnetic field are adjusted to maximize the flow effect of the magnetic fluid and improve the heat dissipation efficiency.
[0036] The circulation pipe 4 is made of plastic pipe. A centrifugal pump 5 is provided on the circulation pipe 4; a flow meter and a flow valve 6 are provided on the circulation pipe 4. The circulation pipe 4 includes a cooling area 7, and the circulation pipe in the cooling area is coiled and laid in the cooling pool for heat exchange. The flow meter, the flow valve 6 and the centrifugal pump 5 are all electrically connected to the controller, and the controller is electrically connected to the magnetic field regulator. The controller can obtain the magnet flow, adjust the power of the centrifugal pump 5 and the opening and closing degree of the flow valve 6, and adjust the magnetic field strength through the magnetic field regulator.
[0037] In this cooling system, when a single-node server is running, the magnetic fluid is affected by the magnetic field, flows rapidly and absorbs heat from the surface of the server components. This process is similar to traditional liquid cooling, but the uniqueness of magnetic fluid is that it can more precisely control the flow path.
[0038] By adjusting the strength and direction of the external magnetic field, the flow of the magnetic fluid can be precisely controlled to optimize the heat dissipation effect. This technology can not only improve the heat dissipation efficiency, but also dynamically adapt to different heat dissipation requirements when the server is running.
[0039] Compared with traditional fan or liquid cooling systems, magnetic fluid cooling has lower energy consumption and smaller space occupation. At the same time, because magnetic fluid can flow freely in a small space, this cooling system can be more flexibly integrated into server design, improving the compactness and performance of the overall system.
[0040] When the operating loads of different node servers in the immersion tank are different and the power consumption of heating elements is different, the automatic control system ensures that the magnetic fluid can always flow effectively along the surface of key components to maximize the heat dissipation efficiency.
[0041] Adjustment of the external magnetic field can precisely control the flow path and flow rate of the magnetic fluid, achieve dynamic heat dissipation regulation, and enable the system to flexibly adapt to different workloads.
[0042] In addition, the utility model designs valves and flow control devices. In order to control the flow of magnetic fluid in different node servers, it is necessary to add valves and flow control devices to adjust the flow and pressure of the magnetic fluid.
[0043] In terms of noise control, since the system uses a magnetic field generator to drive the magnetic fluid for cooling, there is no noise generated by the rotation of traditional fans, so the wind noise caused by fans can be greatly reduced. The system reduces the noise level generated by the server during operation by optimizing the hardware design and adjusting the magnetic fluid flow. This not only improves the working environment quality of the data center, but also facilitates the deployment of servers in places close to residential areas.
[0044] Real-time data analysis and algorithms: Introduce real-time data analysis and intelligent algorithms to dynamically interpret sensor data. This enables the system to make decisions more quickly, respond to changes in server status, and achieve real-time regulation.

Without departing from the spirit and essence of the utility model, ordinary technicians in the field can make various equivalent modifications or substitutions to the embodiments of the utility model, and these modifications or substitutions should be within the scope of the utility model / any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
