Description

TECHNICAL FIELD

[0001] The application relates to the field of liquid cooling equipment, and particularly relates to a server immersion liquid cooling equipment with a gas leakage detection function. BACKGROUND

[0002] With the rapid development of cloud computing, artificial intelligence and big data technology, the computing density and power consumption of data centers continue to rise, which poses unprecedented challenges to heat dissipation technology. Immersion liquid cooling technology, as a revolutionary heat dissipation scheme, directly immerses heat generating elements such as server mainboards in cooling liquid with high insulation and high heat capacity, realizes high-efficiency heat exchange far exceeding traditional air cooling, and has become one of the mainstream directions of high-density data center cooling.

[0003] The prior art mainly relies on simple liquid level sensors or pressure sensors for indirect judgment. This monitoring method can only trigger an alarm when the leakage amount accumulates to a certain extent, causing a significant decrease in the system liquid level or abnormal pressure, and cannot realize early and trace leakage warning, thereby causing damage to server equipment and computer room environment. In addition, there is a lack of an automatic active repair mechanism that can intervene and repair online immediately after leakage is found to minimize the impact of failure. Usually, after confirming the occurrence of leakage, the cooling liquid is emptied, and then professional personnel locate and perform external repair or component replacement. This process causes long-time interruption of server business, high maintenance cost and huge downtime loss. SUMMARY

[0004] In order to make up for the problem that the prior art cannot detect and repair in one step, the application provides a server immersion liquid cooling equipment with a gas leakage detection function.

[0005] The technical scheme adopted by the application to solve the technical problem is that the server immersion liquid cooling equipment with a gas leakage detection function comprises:

[0006] a cavity for storing cooling liquid for server immersion liquid cooling;

[0007] a movement mechanism installed outside the cavity and used for driving the detection and repair mechanism to reciprocally move up and down and rotate left and right around the cavity to prevent dead angles in detection and repair of gas leakage of the cavity;

[0008] a detection and repair mechanism installed above the movement mechanism and used for detecting and repairing gas leakage of the cavity to prevent the cavity from failing to normally operate due to long-time gas leakage;

[0009] a circulation mechanism installed outside the movement mechanism and used for circulating the cooling liquid in the cavity and generating dynamics to prevent the cooling liquid in the cavity from rising in temperature along with the server;

[0010] The detection and repair mechanism includes a disc.

Solenoid valves are installed at the connections between the three-way valves and the three tubes.

An annular slide table is rotatably connected to the annular slide rail.

[0017] Preferably, the top of the lead screw is fixedly connected to a first sprocket through a fixed seat, and the outer ring of the lead screw is fitted with a second sprocket. Neither the first sprocket nor the second sprocket has threads at the position of the lead screw.

[0018] The combined lifting and rotating inspection path eliminates blind spots and avoids missed inspections at the edges of the cavity; high motion accuracy and programmable paths adapt to cavities of different sizes, improving inspection efficiency; stable and deviation-free sprocket drive ensures reliable power transmission and reduces the risk of failure.

[0019] Preferably, the circulation mechanism includes a water pump and a heat exchanger mounted on the outer wall of the fixed base. A third sprocket is fitted around the outer ring of the water pump shaft. A first chain is movably connected to the outer side of the third sprocket and the first sprocket. A liquid extraction pipe and a liquid delivery pipe are respectively fitted between the water pump inlet end and the cavity and between the water pump outlet end and the heat exchanger. A condenser and a heat sink are respectively provided on the outer wall of the heat exchanger. A return pipe is fitted between the heat exchanger and the cavity.

[0020] Preferably, the circulation mechanism further includes four shafts rotatably connected to the inner cavity of the cavity via bearings. The bottom of each shaft is fixedly connected to a fourth sprocket. Two of the fourth sprockets are movably connected to the outside of the second sprockets via a second chain. A third chain is movably connected to the outside of every two fourth sprockets. A stirring blade is fixedly connected to the outer ring of each shaft.

[0021] The water pump drives multiple components with a single power source, simplifying the equipment structure and reducing manufacturing costs and energy consumption; the stirring blades break up thermal stratification, ensuring uniform coolant temperature and improving server heat exchange efficiency and operational stability; the heat exchanger provides efficient heat dissipation, and the closed-loop circulation system is reliable with a low failure rate.

[0022] Preferably, the cavity has a cavity cover on top, an outer shell is fixedly connected to the inner cavity of the cavity, a coolant channel is provided at the bottom of the outer cavity, multiple channel outlets are provided on the coolant channel, and a second spring and a baffle are provided in each channel outlet.

A multi-functional signal acquisition device is provided at the middle position of the cooling equipment array inserted into the inner cavity of the cavity, and a liquid level detector is provided directly above the liquid monitoring tank.

[0023] The liquid monitoring tank prevents false alarms, ensures reliable liquid level detection, and avoids interference from normal fluctuations; the spring baffle enables plug-and-play cooling equipment with minimal leakage during insertion and removal, and facilitates easy replacement; the threaded socket flexibly adapts to cables, reducing the number of interfaces in the signal acquisition equipment and further reducing the risk of leakage.

[0024] The advantages of this invention are:

[0025] 1. This invention integrates a high-definition camera, a high-sensitivity gas sensor, and an ultrasonic sensor to construct a multimodal fusion intelligent sensing system. This system can perform comprehensive scanning of the cavity surface without blind spots, accurately identifying and locating leaks across the entire spectrum, from macroscopically visible seepage to microscopically invisible gas escape, enabling early detection and precise location of potential leaks. Furthermore, it integrates the detection and repair mechanisms into a single unit. Through intelligent decision-making by the controller, the liquid storage tank automatically selects the appropriate repair material, which is then precisely delivered to the leak point via an anti-blocking delivery system for rapid curing and repair. This completely transforms the traditional passive maintenance model that relies on manual labor and system downtime, forming an automatic closed loop of perception, decision-making, and execution. This minimizes the risk of server downtime and maintenance costs associated with leaks, significantly improving the operational reliability and intelligent operation and maintenance level of the immersion liquid cooling system.

[0026] 2. This invention uses a water pump as the core power source, which drives the internal stirring blades and the external scanning motion mechanism simultaneously through a sprocket and chain system. This achieves multi-functionality, efficiently integrating cooling, internal fluid stirring (breaking thermal stratification), and external inspection. It significantly reduces the number of independent drive components, simplifies the overall structure, and lowers manufacturing costs and system energy consumption. Simultaneously, the unique auger and scraper combination structure inside the delivery pipe, combined with a friction-generated heat mechanism, effectively prevents the deposition and blockage of high-viscosity repair materials, ensuring the long-term unobstructed and readily available repair channel. Furthermore, the plug-and-play liquid-tight interface design at the bottom of the cavity and redundant liquid monitoring tanks together constitute a highly integrated, functionally coordinated, and long-term self-maintaining liquid cooling solution. This improves cooling uniformity and efficiency while ensuring long-term operational stability and safety. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a server immersion liquid cooling device with gas leak detection function includes a cavity 100 for storing coolant for server immersion liquid cooling.

[0040] The motion mechanism 200 is installed outside the cavity 100 and is used to drive the detection and repair mechanism 300 to move back and forth up and down and rotate left and right around the cavity 100 to prevent blind spots in the detection and repair of gas leaks in the cavity 100.

[0041] The detection and repair mechanism 300 is installed above the motion mechanism 200 and is used to detect and repair gas leaks in the cavity 100 to prevent the cavity 100 from being unable to operate normally due to prolonged gas leakage.

[0042] The circulation mechanism 400, which is installed outside the motion mechanism 200, is used to circulate the coolant in the cavity 100 and generate dynamics to prevent the coolant in the cavity 100 from rising along with the server temperature.

[0043] Furthermore, such as Figure 2 , Figure 3 and Figure 4As shown, the detection and repair mechanism 300 includes a disc 301. The top of the disc 301 is equipped with an integrated high-definition camera 302, a high-sensitivity gas sensor 303, an ultrasonic sensor 304, and a controller 305. The top of the disc 301 also has a liquid storage box 306. Three tubes 307 are fitted onto one side of the liquid storage box 306. A three-way pipe 308 is fitted onto each of the three tubes 307. A solenoid valve 309 is installed at each connection point between the three-way pipe 308 and the three tubes 307. One side of the three-way pipe 308... A delivery pipe 310 is fitted, and a pump body 311 is fitted into the middle of the delivery pipe 310. A UV lamp is installed around the outer ring of the delivery pipe 310. The liquid storage box 306 has three cavities inside, storing three different repair materials. Based on the integrated high-definition camera 302, high-sensitivity gas sensor 303, ultrasonic sensor 304, and controller 305, the leak type is detected and identified. Different repair materials are used to repair the leak, realizing an automatic closed loop from problem detection to problem resolution. The bottom of the disc 301 is fixedly connected to... A motor 318 is connected to the base of the motor 318, which is fixedly connected to a chassis 319. The chassis 319 and the disc 301 are rotatably connected via bearings. A rotating rod 320 is rotatably connected to the top of the disc 301 via bearings. Pulleys 321 are fitted around the outer rings of the output shaft of the motor 318 and the rotating rod 320. A belt 322 is movably connected to the outside of the two pulleys 321. A gear 323 is fixedly connected to the top of the rotating rod 320. A rack 32, which meshes with the gear 323, is fixedly connected to one side of the liquid storage box 306. 4. Two grooves 325 are provided on the top of the disc 301, and a slider 326 adapted to the grooves 325 is provided on the bottom of the liquid storage box 306. When the motion mechanism 200 drives the detection and repair mechanism 300 to move, visual-assisted positioning is performed first: the integrated high-definition camera 302 continuously collects images of the surface of the cavity 100 to identify visible signs of leakage such as liquid stains, oil stains, and bubbles in real time; once an abnormal area is detected, it immediately provides preliminary coordinates to the high-sensitivity gas sensor 303 to locate the gas concentration. Then the motor 318 drives the disc 301 to rotate, so that the high-sensitivity gas sensor 303 rotates to the position facing the cavity 100. After receiving the visual coordinates, the gas sensor works in sniffing mode to detect the concentration of volatile organic compounds in the specific coolant; by monitoring the concentration gradient, the controller 305 can accurately locate the leak source and determine the leak rate. Subsequently, motor 318 drives disk 301 to rotate, causing ultrasonic sensor 304 to be directly facing the cavity 100. For minute, intermittent, or initial pressure leaks that are difficult to detect by visual and gas sensors, ultrasonic sensor 304 detects relevant signals. Its strong directionality allows for precise leak location and is unaffected by background gas concentration or visible contamination. By fusing sensors based on three different principles—visual, gas, and acoustic—a complementary advantage is achieved: integrated high-definition camera 302 provides macroscopic clues, high-sensitivity gas sensor 303 performs chemical confirmation, and ultrasonic sensor 304 captures physical leak characteristics.This multimodal sensing strategy greatly improves the sensitivity, accuracy, and reliability of leak detection, effectively reducing the risk of false alarms and missed alarms from a single sensor. After detection, the controller 305 integrates the signals from the three sensors to classify and evaluate the leak (e.g., type A is a slow leak, using low-viscosity UV adhesive; type B is a rapid spray, using high-viscosity quick-drying filler). After the decision, the controller 305 activates the material selection mechanism: the motor 318 drives the rotating rod 320 and its top gear 323 to rotate through the transmission system composed of pulley 321 and belt 322; the gear 323 meshes with the rack 324 fixed on the liquid storage box 306, converting the rotational motion into precise linear motion of the liquid storage box 306 along the slide 325 until the delivery pipe 310 is aligned with the leak. Subsequently, the solenoid valve 309 corresponding to the control chamber opens, while the other two solenoid valves 309 remain closed. The pump body 311 extracts repair material at controlled pressure and flow rate, spraying it onto the leak through the delivery pipe 310, ensuring it completely covers or penetrates the leak gap. Curing is then achieved by instantaneous illumination with a UV lamp surrounding the end of the delivery pipe 310, or by utilizing the material's own chemical properties to cure and seal it under air conditions. This design achieves surgical-like precision repair, minimizing the impact on non-leaking areas and significantly shortening the vulnerable period from leak detection to repair completion, achieving an intelligent repair effect that addresses the specific leak. Matching the optimal repair material to different leak characteristics significantly improves the success rate and durability of repairs.

[0044] like Figure 3 and Figure 4As shown, the inner wall of the conveying pipe 310 has slots on all four sides. A round rod 312 is fixedly connected to the inner cavity of each slot. A first spring 313 is fitted around the outer ring of each round rod 312. The outer surface of each first spring 313 is coated with a tin layer. A cross plate 314 is fitted around the outer ring of each of the four round rods 312. An auger 315 is rotatably connected to one side of the cross plate 314 via a bearing. The outer wall of the auger 315 has multiple scrapers 316 that fit against the inner wall of the conveying pipe 310. The cross plate 31... A heat-generating ring 317 is fixedly connected to one side of the pump body 311. Multiple abrasive points are provided at the end of the heat-generating ring 317 that contacts the auger 315. Both the heat-generating ring 317 and the auger 315 are made of carbon steel. When the pump body 311 pumps the repair material into the delivery pipe 310, the material flow drives the auger 315 to rotate. The blades of the auger 315 shear and thin the material (reducing its apparent viscosity) while providing axial thrust to assist the pump body 311 in conveying the material and preventing bridging of the material inside the pipe. Furthermore, the scraper 316, which rotates along with the auger 315, fits tightly against the inner wall of the delivery pipe 310, continuously scraping away any material that may adhere to the pipe wall, fundamentally eliminating the risk of reduced pipe diameter or even blockage caused by material deposition. Meanwhile, the contact ends of the heating ring 317 and the auger 315 are equipped with multiple abrasive points, both made of wear-resistant materials such as carbon steel. As the auger 315 rotates, friction between it and the abrasive points on the heating ring 317 generates heat. This heat is conducted directly to heat the repair material flowing through it, achieving localized and controllable online temperature rise. This effectively reduces the material viscosity, ensuring its flowability and extrudability in low-temperature environments. Furthermore, the combination of the auger 315 and the scraper 316 solves the common clogging problem in automatic dispensing systems, ensuring that repair material is always available. The friction-generated heating design provides a simple and reliable temperature control without an external heat source, enhancing the system's adaptability to ambient temperatures.

[0045] Furthermore, such as Figure 5 and Figure 6As shown, the motion mechanism 200 includes a fixed seat 201 located at the bottom of the cavity 100. The inner cavity of the fixed seat 201 is provided with a lead screw 202 and a limiting rod 203. A square block 204 is fitted around the middle of both the lead screw 202 and the limiting rod 203. A circular hole 205, adapted to the lead screw 202 and the limiting rod 203, is drilled through the square block 204. A hollow plate 206 is fixedly connected between the two square blocks 204. An annular slide rail 207 is provided at the top of the hollow plate 206. An annular slide table 208 is rotatably connected to the annular slide rail 207. The top of the lead screw 202 passes through the fixed seat 201 and is fixedly connected... A first sprocket 209 is connected to the lead screw 202, and a second sprocket 210 is fitted around the outer ring of the lead screw 202. Neither the first sprocket 209 nor the second sprocket 210 has threads at their positions on the lead screw 202. When the water pump 401 is running, its shaft rotates together with the third sprocket 403. During rotation, the first chain 404 causes the first sprocket 209 on the lead screw 202 to rotate, which in turn drives the lead screw 202 to rotate. Since one of the square blocks 204 is restricted from rotating by the limiting rod 203, the rotational motion of the lead screw 202 is converted into a precise vertical lifting motion of the square block 204 and the hollow plate 206 connected to it. At the same time, the electrically powered annular slide 208 integrated on the hollow plate 206 rotates 360 degrees horizontally along the annular slide rail 207. Through the synthesis of vertical and horizontal movements, the entire inspection and repair mechanism 300 fixed on the annular slide 208 forms a continuous path along the outer surface of the cavity 100, covering the vertical lifting and circular rotation of the cavity 100. This achieves a thorough and programmed inspection of the surface of the cavity 100 without blind spots. The programmable path gives the system flexibility and allows for optimization for different models of the cavity 100, greatly improving inspection efficiency and ensuring comprehensive monitoring. Furthermore, neither the first sprocket 209 nor the second sprocket 210 has threads at the position of the lead screw 202, which prevents displacement that could hinder rotation when they rotate together with the lead screw 202.

[0046] Furthermore, such as Figure 5 and Figure 6As shown, the circulation mechanism 400 includes a water pump 401 and a heat exchanger 402 mounted on the outer wall of the fixed base 201. A third sprocket 403 is fitted onto the outer ring of the shaft of the water pump 401. A first chain 404 is movably connected to the outer side of the third sprocket 403 and the first sprocket 209. A liquid extraction pipe 405 and a liquid delivery pipe 406 are respectively fitted between the water inlet end of the water pump 401 and the cavity 100, and between the water outlet end of the water pump 401 and the heat exchanger 402. A condenser 407 and a heat sink 408 are respectively provided on the outer wall of the heat exchanger 402. A return pipe 409 is fitted between the heat exchanger 402 and the cavity 100. The circulation mechanism 400 also includes four shafts 410 rotatably connected to the inner cavity of the cavity 100 via bearings. A fourth sprocket 411 is fixedly connected to the bottom of each shaft 410. Two of the fourth sprockets 411 are connected to the second sprocket 209 via a first chain 404. The external parts of the 10 are movably connected to a second chain 412, and the external parts of every two fourth sprockets 411 are movably connected to a third chain 413. The water pump 401 is the core of the cooling cycle. During operation, the third sprocket 403 on its power output shaft transmits power to the first sprocket 209 at the top of the lead screw 202 through the first chain 404. This not only provides power for the scanning motion, but more importantly, through the second sprocket 210 and second chain 412 on the lead screw 202 and the fourth sprocket 411 and third chain 413 on the shaft 410 inside the cavity 100, the power is distributed to multiple shafts 410, driving the stirring blades on their outer ring to rotate slowly. This breaks the thermal stratification phenomenon caused by uneven heat generation in the cavity 100, making the coolant temperature field more uniform, improving the overall heat exchange efficiency and the stability of the server operation.

[0047] Furthermore, such as Figure 7 , Figure 8 as well as Figure 9As shown, a cavity cover 101 is provided on the top of the cavity 100. An outer shell 102 is fixedly connected to the inner cavity of the cavity 100. A coolant channel 103 is provided at the bottom of the outer side of the cavity 100. Multiple channel outlets 104 are provided on the coolant channel 103. Each channel outlet 104 is equipped with a second spring 105 and a baffle 106. Multiple sockets 107 are threaded onto the inner wall of the cavity 100. A liquid monitoring tank 108 is provided in the space between the cavity 100 and the outer shell 102. A shielding plate is provided at the inlet of the liquid monitoring tank 108. A multi-functional signal acquisition device 109 is provided at the middle position of the cooling equipment array inserted into the inner cavity of the cavity 100. The liquid monitoring tank 108... A liquid level detector is installed directly above the liquid level monitoring tank 108. A shielding plate at the inlet of the liquid monitoring tank 108 prevents liquid from flowing in during normal fluctuations. Only when a leak occurs in the chamber 100, causing the liquid level to rise abnormally to a certain height, will the coolant overflow the shielding plate and flow into the liquid monitoring tank 108. The liquid level detector, positioned directly above the liquid monitoring tank 108, accurately determines the liquid level in the chamber 100 based on the returned feedback signal. This avoids direct contact between the sensor and the main coolant flow, reducing the risk of sensor damage and reading interference, extending sensor lifespan, and improving monitoring reliability. Finally, in the middle of the inserted cooling equipment array… It also integrates a multi-functional signal acquisition device 109, which can collect key parameters such as temperature, flow rate, and pressure in a unified manner and aggregate them into a single signal output, minimizing the number of external interfaces, thereby reducing potential leakage risks, simplifying the wiring structure, and improving the reliability of data acquisition. The channel outlet 104 is precisely connected to the liquid injection port of each cooling device. After the coolant enters from the bottom, it is injected from bottom to top into the interior of the vertically inserted cooling device through the liquid injection port, forming a cooling path of "bottom liquid inlet - heat exchange inside the device - natural return". At the same time, each channel outlet 104 is equipped with a second spring 105 and a baffle 1. 06. When the device is not inserted, the second spring 105 keeps the baffle 106 in the closed state, sealing the interface. During insertion, the connector presses down on the baffle 106, automatically opening the flow channel and allowing coolant to flow into the device, achieving a "plug-and-play" liquid-tight connection. This greatly reduces coolant leakage and flow loss during insertion and removal. At the same time, this structure ensures that each computing node can obtain a stable coolant flow, eliminating the risk of local overheating caused by uneven flow. The socket 107 is installed using a multi-hole threaded connection, which not only allows for flexible replacement according to different cable types such as power, low-voltage, and fiber optic cables, but also ensures excellent sealing performance at the interface.

The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
