Description

Technical Field

[0001] This utility model relates to the field of insulating oil circulating cooling devices, and more particularly to data center insulating oil circulating cooling devices. Background Technology

[0002] In data center operations, the continuous operation of electronic devices generates a significant amount of heat, making a reliable cooling system crucial for ensuring stable and efficient operation. Insulating oil circulating cooling devices, with their excellent heat dissipation and electrical insulation properties, are widely used in data centers. Their operation involves the insulating oil passing through heat dissipation pipes and cooling modules, cooling down, and then being collected in a storage tank. It is then pumped back out, repeating this cycle to dissipate heat from the data center equipment.

[0003] However, traditional data center insulating oil circulating cooling devices have many problems that urgently need to be solved in the critical stage of connecting the storage tank and the pipeline to the storage tank.

[0004] The connection between the pipes and the storage tank is not secure enough. Under long-term impact from the circulating insulating oil, the connection is prone to loosening, which can lead to insulating oil leakage. This not only reduces cooling efficiency and interferes with the normal heat dissipation of the data center, but may also cause short circuits and other faults due to the leakage of insulating oil into electrical equipment, posing a great safety hazard. Furthermore, the pipes are usually connected by a single flange, which has poor sealing performance and is difficult to effectively prevent the leakage of insulating oil. Once a leak occurs, it will pollute the surrounding environment and increase operation and maintenance costs.

[0005] Therefore, we propose a data center insulating oil circulating cooling device. Utility Model Content

[0006] This invention addresses the technical problems existing in the prior art, namely, the connection between the pipe and the storage box is not stable enough. Under long-term impact from the circulating insulating oil, the connection is prone to loosening, which can lead to insulating oil leakage. This not only reduces cooling efficiency and interferes with the normal heat dissipation of the data center, but may also cause short circuits and other faults due to the leakage of insulating oil into electrical equipment, posing a great safety hazard. Furthermore, the pipes are usually connected by a single flange, which has poor sealing performance and is difficult to effectively prevent the leakage of insulating oil. Once a leak occurs, it will pollute the surrounding environment and increase operation and maintenance costs.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] A data center insulating oil circulating cooling device includes an insulating oil collection tank. Inside the insulating oil collection tank is an oil outlet filter pipe assembly. A branch pipe connection assembly is provided at the connection point of the oil outlet filter pipe assembly. The branch pipe connection assembly is inserted into the oil outlet filter pipe assembly, and a flange connection assembly is provided between the two. The flange connection assembly is used to connect the two, enhance sealing, and monitor leakage at the connection point. A buffer support structure is provided at the bottom of the branch pipe connection assembly to support and buffer the branch pipe connection assembly.

[0009] As a preferred embodiment of this utility model, the oil outlet filter pipe assembly includes an oil inlet pipe, the outer surface of the oil inlet pipe is provided with a first connecting thread, the connection of the oil inlet pipe is also provided with an installation fitting, the interior of the installation fitting is provided with a filter element, the inner wall of the installation fitting is provided with a second connecting thread, and the right side wall of the oil inlet pipe is also provided with a sealing groove.

[0010] As a preferred embodiment of this utility model, the branch pipe connection assembly includes a main pipe, a first sealing plug plate is installed on the left side wall of the main pipe, a connecting pipe is provided on the right side wall of the main pipe, and a plurality of branch pipes are provided on the right side wall of the connecting pipe.

[0011] As a preferred embodiment of this utility model, the buffer support structure includes a plurality of support rods, a fixing plate is installed at the bottom of the plurality of support rods, a rubber base is provided below the fixing plate, a plurality of dampers are provided inside the rubber base, and a buffer spring is provided on the outside of the plurality of dampers.

[0012] As a preferred embodiment of this utility model, the flange connection assembly includes a first connecting flange and a second connecting flange. A balancing connecting groove is formed on the outer surface of both the first and second connecting flanges. A plurality of sealing bolts are provided between the two balancing connecting grooves. An elastic connecting sealing ring is fitted onto the outer surface of both the first and second connecting flanges and located on the outer surface of the two balancing connecting grooves. A detection cavity is formed on the inner wall of the first connecting flange. A sealing insertion groove is formed inside the detection cavity. Two mounting seats are installed on the inner wall of the detection cavity. A pressure sensor is provided at the connection point of the two mounting seats. A second sealing insertion plate is provided on the inner wall of the second connecting flange.

[0013] As a preferred embodiment of this utility model, when the oil inlet pipe is connected to the conduit pipe, the first sealing plug plate is inserted into the sealing groove, and the mounting fitting is threadedly connected to the first connecting thread of the oil inlet pipe through the filter element, thereby making it detachable.

[0014] As a preferred embodiment of this utility model, when the first connecting flange and the second connecting flange are connected, the second sealing plug plate of the second connecting flange is inserted into the sealing plug groove of the first connecting flange, thereby forming an auxiliary seal. At this time, the detection chamber is in a separate sealed space. The air pressure sensor is used to monitor the pressure of the detection chamber and determine whether there is a leak based on the air pressure change. The elastic connecting sealing ring is used to seal the outermost connection between the second connecting flange and the first connecting flange to prevent a large amount of insulating oil from leaking out during maintenance.

[0015] In a preferred embodiment of this utility model, the damper and the buffer spring are installed between the rubber base and the fixing plate, and the support rod is connected to the branch pipe.

[0016] The beneficial effects of this utility model are as follows: the oil outlet filter pipe assembly and the branch pipe connection assembly are connected by a flange connection assembly. A sealing groove is opened on the right side wall of the oil inlet pipe, and a first sealing plug plate is installed on the left side wall of the outlet pipe. When the two are connected, the first sealing plug plate is inserted into the sealing groove to form the first sealing barrier. The second sealing plug plate of the second connecting flange is inserted into the sealing plug groove of the first connecting flange to form an auxiliary seal. At the same time, an elastic connecting sealing ring is fitted on the outer surface of the first connecting flange and the second connecting flange to seal the outermost connection. This multi-seal design effectively prevents the leakage of insulating oil and avoids environmental pollution and increased operation and maintenance costs caused by the leakage of insulating oil.

[0017] The inner wall of the first connecting flange has a detection chamber, in which a pressure sensor is installed. When the first connecting flange is connected to the second connecting flange, the detection chamber forms a separate sealed space. Once the insulating oil leaks, the air pressure in the detection chamber will change, and the pressure sensor can detect this change in time, thereby realizing real-time leakage monitoring at the connection. This allows for timely detection of problems in the early stages of leakage, enabling maintenance measures to be taken to prevent large-scale leakage of insulating oil and ensure the safe operation of the data center.

[0018] The installation fitting in the oil outlet filter pipe assembly contains a filter element. The installation fitting is threaded to the first connection thread of the oil inlet pipe via a second connection thread. This detachable design facilitates the replacement and maintenance of the filter element. When the filter element is clogged or needs to be replaced, there is no need to disassemble the entire pipe assembly. Simply unscrew the installation fitting. This greatly saves maintenance time and labor costs, ensures the filtration effect of the insulating oil, and improves cooling efficiency.

[0019] A buffer support structure is installed at the bottom of the branch pipe connection assembly. This structure includes a support rod, a fixed plate, a rubber base, a damper, and a buffer spring. The support rod is connected to the branch pipe and transmits vibrations to the buffer support structure. The rubber base itself has a certain vibration damping effect, while the damper and buffer spring are installed between the rubber base and the fixed plate to further absorb and buffer the vibrations generated during the operation of the device, reduce vibration damage to the pipe assembly, and extend the service life of the device.

[0031] Example

[0032] Please see Figure 1-6 The oil outlet filter pipe assembly and the branch pipe connection assembly are connected by a flange connection assembly, which is the core foundation of the entire sealing structure. The right side wall of the oil inlet pipe 101 is carefully designed with a sealing groove 106. Its shape and size are precisely designed based on fluid mechanics and sealing principles. The purpose is to perfectly fit the first sealing plug plate 202 installed on the left side wall of the main pipe 201. When the oil inlet pipe 101 and the main pipe 201 are connected, the first sealing plug plate 202 can be inserted into the sealing groove 106 with a tight fit due to its precise size and shape tolerance. From the perspective of sealing principle, this plug-in method belongs to surface contact sealing. Through the extremely small gap between the two, it can form a strong barrier to the leakage of insulating oil in the initial stage, effectively preventing the insulating oil from seeping out from this key part.

[0033] The design of the second sealing plug plate 310 fully considers pressure distribution and fluid permeation path. When it is inserted into the sealing plug groove 307 of the first connecting flange 301, it forms a relatively independent and highly sealed space inside the pipeline. In this process, the mechanical seal principle is utilized. Through precise structural design and dimensional control, the contact pressure between the sealing plug plate and the sealing plug groove 307 is evenly distributed, further compressing any possible micro-leakage channels and preventing insulating oil from leaking from the inside. Moreover, the elastic connecting sealing ring 305 fitted on the outer surface of the first connecting flange 301 and the second connecting flange 302 is made of a special elastic sealing material. This material possesses excellent oil resistance, aging resistance, and high elasticity. During installation, the elastic connection sealing ring 305 is pre-compressed. Once the two flanges are connected and tightened, it will fit tightly against the outer surface of the two flanges due to its own elastic deformation characteristics. In actual operation, when the pipeline is affected by internal insulating oil pressure fluctuations or external vibrations, the elastic connection sealing ring 305 can adaptively adjust the degree of deformation to maintain a good sealing state. This multi-layered and all-round multi-seal design from the inside to the outside fundamentally avoids a series of serious problems such as environmental pollution and a significant increase in operation and maintenance costs that may be caused by insulating oil leakage.

[0034] The inner wall of the first connecting flange 301 is specially provided with a detection chamber 306. Inside the detection chamber 306, a high-precision air pressure sensor 309 is installed. This air pressure sensor 309 has many excellent characteristics such as high sensitivity, fast response, and stability and reliability. After the first connecting flange 301 and the second connecting flange 302 are connected through a series of precise assembly processes, the detection chamber 306 forms a relatively independent and sealed space. Its working principle is based on the gas state equation and pressure balance theory. Under normal and stable operating conditions, the gas in the detection chamber 306 is in a pressure balance with the external environment and the insulating oil inside the pipeline. At this time, the air pressure value monitored by the air pressure sensor 309 remains within a relatively stable range. However, once the insulating oil leaks, whether the insulating oil seeps into the detection chamber 306 from inside the pipeline or external air enters the detection chamber 306 through tiny gaps, it will disrupt the original stable pressure balance inside the detection chamber 306.

[0035] Specifically, if insulating oil seeps into the detection chamber 306, it will occupy a certain space within the chamber, causing the gas inside to be compressed. According to the gas law, under constant temperature conditions (the temperature change within the detection chamber 306 is negligible in actual operation), the decrease in gas volume will cause an increase in gas pressure. Conversely, if external air enters the detection chamber 306, it will increase the amount of gas inside, also causing a change in gas pressure. The pressure sensor 309 can detect these extremely minute changes in gas pressure with extreme sensitivity. It converts the pressure change into an electrical signal through a precise internal pressure sensing element, which is then amplified and filtered. After a series of processing steps, the signals are accurately transmitted to external monitoring equipment or systems. Through analysis and processing of these electrical signals, the monitoring system can quickly determine whether a leak exists and its approximate extent. This allows for timely detection of the problem in its early stages, buying valuable time for subsequent maintenance measures and effectively preventing large-scale leakage of insulating oil. This fundamentally ensures the safe and stable operation of the data center. By monitoring air pressure changes in real time and accurately, the leak point can be located quickly and accurately, providing an accurate and reliable basis for timely and efficient maintenance work and avoiding greater losses caused by delayed detection of leaks.

[0036] The mounting fitting 103 in the oil outlet filter pipeline assembly contains a filter element 104. The design and selection of the filter element 104 are determined comprehensively based on the characteristics of the insulating oil (such as viscosity and impurity composition) and the filtration accuracy requirements of the cooling system. The mounting fitting 103 and the oil inlet pipeline 101 are connected by threads. This connection method has a solid mechanical connection principle. The first connecting thread 102 on the outer surface of the oil inlet pipeline 101 and the second connecting thread 105 on the inner wall of the mounting fitting 103 are precisely designed and manufactured with parameters such as thread profile and pitch to ensure that the two can achieve a tight and reliable engagement. During the installation process, the operator can use a special tool to screw the mounting fitting 103 into the oil inlet pipeline 101 according to the specified torque and rotation direction. Through the mutual engagement of the threads, a detachable fixed connection between the mounting fitting 103 and the oil inlet pipeline 101 is achieved.

[0037] When the filter element 104 becomes clogged or reaches the end of its service life and needs to be replaced during long-term use, the advantages of this threaded connection are fully demonstrated. The operator only needs to use the appropriate disassembly tools to turn the installation fitting 103 in the opposite direction of the installation. Due to the guiding and separating effect of the thread, the installation fitting 103 can be easily separated from the oil inlet pipe 101. Compared with the traditional whole replacement method, this design does not require complex disassembly and reinstallation of the entire pipeline assembly, which greatly saves maintenance time and labor costs. Moreover, by regularly replacing or cleaning the filter element 104, it can be ensured that the impurities in the insulating oil are effectively removed before entering the subsequent stages of the cooling system. This not only avoids the wear of impurities on subsequent cooling system components (such as pump body, heat dissipation pipes, etc.), but also ensures the good fluidity and heat exchange performance of the insulating oil, thereby improving the cooling efficiency and ensuring the stable and efficient operation of the cooling device.

[0038] The buffer support structure at the bottom of the branch pipe connection assembly includes several key components such as a support rod 401, a fixing plate 402, a rubber base 403, a damper 404, and a buffer spring 405. The support rod 401 and the branch pipe 204 are connected by a high-strength method, such as welding or a high-precision mechanical connection, to ensure that the vibration can be stably and reliably transmitted from the branch pipe 204 to the buffer support structure during vibration transmission. When the device is running, vibrations will be generated due to various factors such as the operation of the pump body and the impact of the flow of insulating oil. These vibrations will first act on the branch pipe 204 and then be transmitted to the entire buffer support structure through the support rod 401.

[0039] The rubber base 403, as the basic component of the buffer support structure, is made of specially selected high-elasticity rubber material. This material has excellent damping characteristics and elastic recovery ability. When vibration is transmitted to the rubber base 403, it absorbs part of the vibration energy through its own elastic deformation, acting like a soft cushion to effectively buffer the impact of vibration. The damper 404 and the buffer spring 405 are installed between the rubber base 403 and the fixed plate 402, each playing a unique and synergistic role. The damper 404 typically employs fluid damping or mechanical damping principles. Taking fluid damping as an example, when vibration occurs, the fluid inside the damper 404 flows in a specially designed channel. Due to the viscosity of the fluid and the resistance of the channel, the vibration energy is converted into heat energy and other forms of energy consumption. The damper 404 and the buffer spring 405 work together to effectively suppress and buffer vibrations of different frequencies and amplitudes, reducing damage to pipe components and extending the service life of the device. This buffer and shock absorption structure ensures that pipe components remain stable in complex vibration environments, reducing potential problems such as loose connections and pipe ruptures caused by vibration, and providing a solid guarantee for the reliable operation of the data center insulating oil circulating cooling device.

[0040] Detailed summary of the workflow

[0041] When the insulating oil reaches the oil outlet filter pipe assembly through the branch pipe connection assembly, it is filtered by the oil outlet filter pipe assembly and returns to the insulating oil collection box 1, and then flows back to the heat dissipation system through other pipes.

[0042] The main pipe 201 of the branch pipe connection assembly is connected to the inlet pipe 101 of the oil outlet filter pipe assembly via a flange connection assembly. The first connecting flange 301 and the second connecting flange 302 are fixed by the balancing connecting groove 303 and the sealing bolt 304. The second sealing plug plate 310 of the second connecting flange 302 is inserted into the sealing plug groove 307 of the first connecting flange 301 to form an auxiliary seal. The elastic connecting sealing ring 305 seals the outermost connection to ensure the sealing performance of the connection.

[0043] Leakage monitoring: After the connection is completed, the detection chamber 306 on the inner wall of the first connecting flange 301 forms a sealed space. The pressure sensor 309 monitors the pressure in the detection chamber 306 in real time. If the insulating oil leaks at the connection, the pressure in the detection chamber 306 will change. The pressure sensor 309 will transmit the signal to the monitoring system so that the leakage problem can be detected and dealt with in a timely manner.

[0044] Buffering and vibration reduction: During the operation of the device, the vibration generated is transmitted to the support rod 401 through the branch pipe 204. The rubber base 403, damper 404 and buffer spring 405 in the buffer support structure work together to absorb and buffer the vibration, reducing the damage of vibration to the pipe components.
