Description

Technical Field

[0001] The present invention relates to the technical field of server environment control, and in particular to a control system and equipment applied to a network server environment. Background Art

[0002] In modern network communication systems, network servers are the core components of computer local area networks. Network servers are mainly used to operate network systems and process and store data sent by users. Network servers are usually composed of cabinets, servers installed in the cabinets, switches, routers and other network devices. During the application process, in order to ensure the degree of integration of the equipment, network devices are often arranged in a highly integrated manner in the cabinets.

[0003] Due to the high degree of integration of network servers, a large number of electrical components will generate a lot of heat during their operation. Therefore, in order to ensure the normal operation of the network servers, it is necessary to monitor the ambient temperature of the network servers in real time. At present, the commonly used network server ambient temperature monitoring mainly relies on temperature sensors and fans for cooling. However, conventional air cooling has poor cooling efficiency and is noisy. Therefore, at this stage, some network servers also rely on liquid cooling for cooling.

[0004] At present, liquid-cooled servers mainly rely on pipe cooling, but this cooling method cannot fully dissipate heat in every corner of the server cabinet, and the pipe system is very complicated. Therefore, immersion liquid cooling cabinets have emerged. However, during use, immersion liquid cooling cabinets often require a separate cabinet for liquid replenishment and temperature control. This not only increases the equipment's footprint but is also not conducive to liquid cooling monitoring within the server cabinet.

[0005] At the same time, the current immersion liquid-cooled network servers still have the following problems. First, the current immersion servers set up a control mechanism on one side of the cabinet, which not only occupies a large space but is also mostly connected by pipes. The pipes connect the inner cavity where the server is placed and the refrigeration container. Not only do you need to pay attention to the pipes during maintenance to avoid pipe leakage, but the low circulation efficiency of the coolant also causes low heat exchange efficiency. Secondly, in order to ensure the cooling liquid level and maintain the cooling efficiency, the circulation rate of the coolant needs to be effectively monitored. At present, a liquid level gauge is often used to monitor the liquid level. The detection results are relatively simple and difficult to reflect the cooling efficiency. In addition, there is no supervision means on the side of the pipe. Leakage in the pipe is difficult to detect and an alarm cannot be issued in time, which easily leads to waste of coolant. In view of this, in-depth research on the above problems resulted in this case. Summary of the Invention

[0034] Beneficial effects

[0035] The present invention provides a control system and device for use in a network server environment.

Furthermore, liquid level detection structures and liquid flow detection structures are provided on the upper and lower sides of the external cooling modules, respectively. This allows the cabinet to be connected to the external cooling modules while effectively detecting and controlling the exchange efficiency between the cabinet and the external cooling modules, thereby precisely controlling the cooling effect of the server. The control system also has the following advantages:

[0036] 1. The liquid cooling system improves heat dissipation efficiency, which is especially suitable for high-load server environments. It adopts dynamic flow rate control. The liquid cooling flow rate monitoring structure monitors and adjusts the coolant flow rate in real time, allocates cooling resources on demand, and reduces energy consumption. It is energy-saving and adaptable. It can drive water flow on demand and realize refined flow rate adjustment through water flow drive components to adapt to different load scenarios and reduce ineffective energy consumption.

[0037] 2. It features a multi-protection storage structure with enhanced redundancy and reliability. At least three external cooling modules independently store coolant, providing redundant backup. A single failure does not affect overall operation, resulting in high system fault tolerance. Liquid level and flow alarms are also provided to monitor coolant return in real time. Abnormal flow rates trigger an alarm to prevent overheating caused by cooling interruptions.

[0038] 3. The top access door is equipped with a visual glass window, allowing internal status to be observed without opening the door, reducing the impact of frequent openings on the cooling environment. It adopts a modular plug-in design, with server units inserted vertically into slots and supported by support brackets, supporting hot-swap maintenance and reducing downtime.

[0039] 4. The external cooling module is integrated with the cabinet sidewall to reduce leakage risks.

[0053] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0054] See also Figure 1-11 The present invention provides an implementation scheme: In the application process of modern network servers, in order to improve the operating efficiency of the network servers, ensuring the stability of the network server's external environment is the most important factor. When the network server is running, highly integrated electronic and electrical components will generate a large amount of heat. Therefore, heat dissipation is the most important factor to consider in the environmental factors of modern network servers;

[0055] Due to the high degree of integration of current network servers, conventional air cooling can no longer meet the usage requirements. More server rooms have introduced liquid cooling. Compared with conventional air cooling, liquid cooling has higher heat dissipation efficiency and better heat dissipation effect. For example, immersion liquid cooling radiator is an emerging network server heat dissipation measure at this stage.

[0056] In the application process of immersion liquid cooling servers, the current immersion liquid cooling cabinets mainly adopt a left-right symmetrical structure, with the cabinet on one side and the liquid cooling circulation device on the other. Firstly, they occupy a large area and have many connecting pipes, which are prone to leakage problems. At the same time, the water flow exchange efficiency of the pipes is limited, affecting the heat dissipation efficiency. Secondly, immersion liquid cooling servers often only have liquid level detection, which cannot truly reflect the cooling effect.

[0057] Example 1: To address the above-mentioned problems, the present application discloses a control device for use in a network server environment, including a cabinet 1. The cabinet 1 is a rectangular hollow shell with an access door 11 disposed on the top. The cabinet 1 serves as an external support structure for a server unit 2. A support plate 14 is disposed on one side of the cabinet 1, and an operation panel 15 is disposed on one side of the support plate 14. The operation panel 15 can be used to control the interior of the cabinet 1, reflect monitoring data, and achieve the purpose of human-computer interaction.

[0058] An access door 11 is hinged on the top opening of the cabinet 1. A visual glass window 13 is provided on the access door 11. The situation inside the cabinet 1 can be observed through the access door 11. At the same time, the server unit 2 in the cabinet 1 can be inspected by opening the access door 11. The server unit 2 is inserted into the cabinet 1 by limited insertion. The cabinet 1 is provided with a liquid cooling unit, which immerses the server unit 2 in coolant, thereby using liquid cooling to cool the server and ensure the server's operating efficiency.

[0059] According to the instructions attached Figure 1 -Attached Figure 4 It can be seen that the above-mentioned cabinet 1 is a cavity shell with a rectangular structure. A plurality of sockets are distributed around the outer edge of the top of the cabinet 1. Some of the sockets correspond to the positions of several slots 12. The bottom of the cabinet 1 is a base. Two pairs of rollers 17 are provided at the four corners of the base. The upper cabinet 1 is supported by the base. The rollers 17 on the base can drive the cabinet 1 to move as a whole. Furthermore, several supporting brackets 16 are provided on the base to support several server units 2 to ensure the stability of the posture of several server units 2.

[0060] According to the instruction manual Figure 1 -Attached Figure 4 As can be seen, the aforementioned server units 2 are vertically inserted into the cabinet 1. The cabinet 1 is provided with a plurality of slots 12 corresponding to the server units 2. Under the limiting function of the slots 12, the server units 2 are ensured to be parallel. Then, the sockets on the cabinet 1 are connected to the data interfaces of the server units 2 to realize data transmission connection, which facilitates the maintenance of the server units 2.

[0061] According to the instruction manual Figure 1 -Attached Figure 11It can be seen that the above-mentioned liquid cooling unit includes a protective storage structure 3 arranged outside the cabinet 1, a liquid cooling flow rate monitoring structure 4 and a liquid level warning structure 5 arranged on the cabinet 1 and the protective storage structure;

[0062] Specifically, the protective storage structure 3 is wrapped around the outside of the cabinet 1. The protective storage structure 3 serves the purpose of wrapping the cabinet 1. At least three protective storage structures 3 are set on the cabinet 1, and insulating coolant is stored in the protective storage structure 3. The protective storage structure 3 has three specific functions. First, the protective storage structure 3 is connected to the inside of the cabinet 1 for circulating and storing coolant. Secondly, it plays a role of sealing and protecting the inside of the cabinet 1. The protective effect inside the cabinet 1 is improved by the wrapping effect. As a circulation space, the coolant can be refluxed for cooling. Finally, the protective storage structure 3 is equipped with a liquid cooling flow rate monitoring structure 4 and a liquid level warning structure 5 to connect the cabinet 1 and the protective storage structure 3, which plays a role in adjusting the cooling efficiency.

[0063] Furthermore, according to the instructions Figure 1 -Attached Figure 6 As can be seen, the liquid cooling flow rate monitoring structure 4 pumps the coolant into the cabinet 1 to complete the coolant injection, and the server units 2 are cooled by the coolant. After the cooling is completed, the coolant flows upward and then flows back to the protective storage structure 3 through the liquid level warning structure 5.

[0064] According to the instruction manual Figure 1 -Attached Figure 8 It can be seen that the liquid level warning structure 5 is arranged on the protective storage structure 3. The liquid level warning structure 5 is used to monitor the return water flow while the coolant refluxes. When the return water flow rate is lower than the critical value, an alarm is triggered. On the one hand, it monitors whether the coolant circulation is stable, and on the other hand, it serves as an alarm in case of leakage.

[0065] According to the instruction manual Figure 1 -Attached Figure 11 It can be seen that the above-mentioned protective storage structure 3 includes an external cooling module 31, one side of the external cooling module 31 is integrally formed with the side wall of the cabinet 1, and the external cooling module 31 is used as a storage space for the equipment coolant, and the coolant is refrigerated at the same time. The bottom of the external cooling module 31 is provided with a connecting port 32 connected to the inside of the cabinet 1, and the connecting port 32 serves as a circulation inlet for the cooling medium. The top of the external cooling module 31 is provided with a reflux port 33 connected to the liquid level warning structure 5, and the reflux port 33 serves as a circulation return port for the cooling medium.

[0066] According to the instruction manual Figure 5 -Attached Figure 11It can be seen that the above-mentioned external cooling module 31 includes an outer shell 311, which is a rectangular shell. A coolant storage tank 312 is provided on one side of the outer shell 311 close to the cabinet 1. A liquid outlet 313 is provided at the bottom of the coolant storage tank 312 to communicate with the communicating vessel 41. A return port 33 is provided on the top of the coolant storage tank 312 to communicate with the liquid level warning structure 5. An air deflector 314 is provided on one side of the external cooling module 31. A cooling plate 3141 is provided on one side of the coolant storage tank 312 corresponding to the air deflector 314. The air deflector 314 actively cools the cooling plate 3141 by actively generating air flow. The cooling plate 3141 exchanges heat with the coolant storage tank 312 to dissipate the heat of the circulated coolant.

[0067] During the specific implementation process, the outer shell 311 is the supporting structure of the external cooling module 31. The outer shell 311 is integrally formed with the side wall of the cabinet 1. The outer shell 311 is divided into two layers, of which the inner layer side close to the cabinet 1 is a coolant storage tank 312. The coolant storage tank 312 is a closed rectangular box that plays the role of storing coolant. It is closer to the cabinet 1 to facilitate the circulation of coolant. The specific coolant storage tank 312 is provided with a reflux port 33 and a liquid outlet 313 that are respectively connected to the manifold 41 and the liquid level warning structure 5. The circulation of coolant is achieved through the cooperation of the liquid level warning structure 5 and the manifold 41.

[0068] Furthermore, another layer of the outer shell 311 is an air deflector 314, which uses the air deflector 314 to generate cooling air to cool the cooling plate 3141, thereby cooling the coolant in the coolant storage tank 312. Specifically, the air deflector 314 includes an air circulation groove 3142. The air circulation groove 3142 is provided on one side of the outer shell 311 parallel to the coolant storage tank 312. An air guide fan 3143 is provided on the top of the air circulation groove 3142. The cooling plate 3141 is provided corresponding to the coolant storage tank 312. The cooling plate 3141 is a metal plate with high heat conduction efficiency. A plurality of cooling fins are arranged in a linear array on the cooling plate 3141 and are arranged in the air circulation groove 3142. A sealing net 3144 is provided at the bottom of the air circulation groove 3142.

[0069] During the specific implementation process, the air circulation groove 3142 is arranged parallel to the coolant storage tank 312, so that the air generated by the air guide fan 3143 flows through the cooling plate 3141. The cooling fins on the cooling plate 3141 increase the contact area and dissipate heat more quickly. Then, the cooling plate 3141 absorbs the heat in the coolant storage tank 312 through heat conduction, thereby cooling the coolant. In this way, the coolant is circulated again to cool the server units 2 in the cabinet 1. Since the outer shell 311 is integrally arranged with the cabinet 1, even if the cabinet 1 leaks, the coolant will not leak. Instead, it will flow into the coolant storage tank 312. In addition, during the coolant circulation process, the dependence on pipelines is reduced, avoiding the risk of leakage while enabling more flexible adjustment of the coolant circulation rate, accurately improving the cooling efficiency. In order to monitor the liquid flow and liquid level without pipelines, the liquid level warning structure 5 and the liquid cooling flow rate monitoring structure 4 are required.

[0070] According to the instruction manual Figure 1 -Attached Figure 8 It can be seen that the present application discloses a liquid level warning structure 5 including an overflow port 51. The overflow port 51 is provided at the top of the side wall of the cabinet 1. The return port 33 is connected to the overflow port 51. The overflow port 51 is provided on the inner wall of the cabinet 1. The overflow port 51 is higher than the top of the server unit 2 in the cabinet 1. This ensures that the coolant completely immerses the server unit 2. A liquid flow detector 52 is provided between the return port 33 and the overflow port 51. The liquid flow detector 52 detects the water flow passing between the overflow port 51 and the return port 33. The overflow port 51 is a long strip through groove. A filter screen 53 is provided near the inner side of the cabinet 1 of the overflow port 51. The filter screen 53 is used to filter and intercept one side of the overflow port 51 to prevent impurities from flowing into the external cooling module 31 through the overflow port 51.

[0071] Furthermore, according to the instructions Figure 1 -Attached Figure 8 It can be seen that the above-mentioned reflux port 33 is a trumpet-shaped groove enlarged at the inlet end, and its cross-sectional size is smaller than the overflow port 51. The reflux port 33 plays a flow collecting role, making it easier for the liquid flow detector 52 to detect the water flow. Specifically, the above-mentioned liquid flow detector 52 is a photoelectric detector. The liquid flow detector 52 includes a mounting port 521. The top of the external cooling module is provided with a mounting port 521. The mounting port 521 is connected to a mounting plate 522 by a thread. The bottom of the mounting plate 522 is provided with an extension rod 523. The extension rod 523 extends into the overflow port 51. A photoelectric detection probe 524 is provided on the extension rod 523. The photoelectric detection probe 524 is a reflective photoelectric detection probe 524. A reflector 525 is correspondingly provided below the mounting port 521. The photoelectric detection probe 524 is provided with an emitting light source 526, and a long strip-shaped receiver 527 is provided corresponding to the emitting light source 526.

[0072] During the specific implementation process, the mounting port 521 is used as the mounting space for the photoelectric detector. The detection end of the photoelectric detector faces the detection port. The photoelectric detector is separately installed on the mounting port 521 through the mounting plate 522. The extension rod 523 is used as an extension to extend the photoelectric detection probe 524 into the detection port. The photoelectric detection probe 524 adopts the reflection detection principle. A reflector 525 is provided at the lower part of the mounting port 521. The emitting light source 526 of the photoelectric detection probe 524 emits a detection light beam. The light beam irradiated by the reflector 525 will return to the receiver 527. The receiver 527 is provided with a plurality of photosensitive elements arranged in a matrix. Since the overflow trough discharges the reflux water in the cabinet 1 from the reflux trough back to the external cooling module 31, when the water level changes, the refraction angle of the light beam emitted by the emitting light source 526 changes due to the change in the water level depth. When the light beam is reflected to the receiver 527, due to the change in the refraction angle, it will illuminate different positions of the receiver 527. The depth of the reflux water level is determined based on the receiving position data of the receiver 527, thereby determining the reflux water level data.

[0073] According to the instruction manual Figure 1 -Attached Figure 6 As can be seen, the liquid cooling flow rate monitoring structure 4 includes a communication vessel 41, one side of which is in communication with the bottom of the external cooling module 31, and the other side of which is in communication with the communication port 32. A liquid flow monitoring component 42 is mounted on the communication vessel 41, and the liquid flow monitoring component 42 is used to monitor the flow rate of the coolant between the protective storage structure 3 and the cabinet 1. A water flow driving component 43 is provided on the communication vessel 41, and the water flow driving component 43 is used to control the flow rate of the liquid.

[0074] During the specific implementation process, the communicating vessel 41 is an extension of the bottom of the external cooling module 31, serving as the installation space of the liquid cooling flow rate monitoring structure 4. The communicating vessel 41 is an L-shaped cavity shell with a rounded cross-section. A pair of closed grooves 431 are provided at both ends of the communicating vessel 41. The pair of closed grooves 431 are respectively connected to the connecting port 32 and the liquid outlet 313, which serve to connect the external cooling module 31 with the cabinet 1. At the same time, the entire liquid cooling flow rate monitoring structure 4 is protruded, which is convenient for maintenance and inspection of the liquid cooling flow rate monitoring structure 4. The communicating vessel 41 is connected to the liquid outlet 313 at the bottom of the external cooling module 31 so that the cooled water flows back to the cabinet 1 through the water flow driving component 43. According to the operating temperature of the server, the operating frequency and power of the water flow driving component 43 are controlled, the water flow circulation rate is changed, and the heat dissipation efficiency is improved. The water flow rate is detected by the liquid flow monitoring component 42 as a feedback signal to monitor the circulation rate of the water flow.

[0075] According to the instruction manual Figure 1 -Attached Figure 11It can be seen that the above-mentioned liquid flow monitoring component 42 includes a liquid flow monitoring groove 421. The liquid flow monitoring groove 421 is opened on the communicating vessel 41. A swirl flow velocity detector is installed on the liquid flow monitoring groove 421. The swirl flow velocity detector monitors the liquid flow velocity passing through the liquid flow monitoring groove 421.

[0076] Specifically, the swirl flow velocity detector includes a detection frame 422, which is mounted on a liquid flow monitoring tank 421. The detection frame 422 is provided with a detection ring groove 423, in which a detection impeller 424 is mounted. The axle of the detection impeller 424 is externally sleeved on a star-shaped detection seat 425, and the tip of the star-shaped detection seat 425 is provided with a plurality of detection magnets 426. A detection housing is provided on one side of the detection ring groove 423, and a Hall sensor 427 is provided in the detection housing. The position of the Hall sensor 427 corresponds to the position of the detection magnet 426.

[0077] In the specific implementation process, the detection frame 422 is fixedly installed through the liquid flow monitoring groove 421, and the detection frame 422 is used as the supporting body. A detection ring groove 423 is fixedly provided at the bottom of the detection frame 422, and the detection impeller 424 is installed through the detection ring groove 423. The detection impeller 424 can rotate in the detection ring groove 423. When the coolant on one side of the external cooling module 31 flows into the cabinet 1 under the action of the water flow driving component 43, the water flow impacts the detection impeller 424, thereby causing the detection impeller 424 to rotate, and then the detection impeller 424 is used to drive the star-shaped detection seat 425 to rotate. During the rotation process, the several detection magnets 426 on 5 periodically approach the Hall sensor 427. The magnetic force exerted on the Hall sensor 427 changes periodically. The frequency of the magnetic force change detected by the Hall sensor 427 is used as the basis for judging the water flow rate. Specifically, when the change frequency is high, it proves that the detection impeller 424 rotates faster, and the liquid flow rate is high at this time. Through this magnetic detection device built into the liquid flow channel, the circulation rate of the coolant can be expressed very accurately even without using a pipeline for liquid flow metering, thereby facilitating the measurement of the liquid flow exchange efficiency between the cabinet 1 and the external cooling module 31, and more accurately controlling the cooling rate.

[0078] According to the instruction manual Figure 1 -Attached Figure 11 As can be seen, the water flow drive assembly 43 includes a drive motor 432, which is arranged on one side of the communicating vessel 41. A water-displacing roller 433 is provided on one side of the communicating vessel 41. A drive shaft 434 is provided on the central axis of the water-displacing roller 433. The drive shaft 434 passes through one side of the communicating vessel 41 and is sealed with a sealing gasket. The driving end of the drive motor 432 is connected to a gear box 435, which is connected to the drive shaft 434.

[0079] During the specific implementation process, the water flow drive component 43 is arranged on the external cooling module 31 with a split structure, and the gear box 435 is driven by the driving motor 432 to operate, so that the gear box 435 drives the driving shaft 434 to rotate, and then the driving shaft 434 drives the water-pumping roller 433 to rotate. The water-pumping roller 433 is a number of fan-shaped plates staggered on the driving shaft 434, and the water-pumping roller 433 matches the inner cavity diameter of the communicating vessel 41. At the same time, the driving shaft 434 cooperates with the sealing gasket to prevent leakage on one side of the driving shaft 434. A multi-stage reduction gear is arranged in the gear box 435, and the gear box 435 is connected to the side of the communicating vessel 41 by screws. The torque of the driving motor 432 is amplified through the multi-stage reduction of the gear box 435, thereby increasing the output torque on one side of the water-pumping roller 433.
