Description

Technical Field

[0001] The present invention relates to the technical field of server environment control, and specifically to a control system and device 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, process and store data sent by users. Network servers usually consist of network devices such as cabinets, servers installed in the cabinets, switches, and routers. In the application process, in order to ensure the integration degree of the devices, the network devices are often arranged in a highly integrated manner in the cabinet.

[0003] Due to the high integration of network servers, a large number of electrical components will generate a lot of heat during the operation of network servers. Therefore, in order to ensure the normal operation of network servers, it is necessary to monitor the environmental temperature of network servers in real time. At present, the monitoring of the environmental temperature of network servers mainly relies on temperature sensors and fans for cooling. However, the conventional air-cooling method has poor cooling efficiency and high noise. Therefore, there are also network servers that rely on liquid cooling at present.

[0004] At present, the liquid-cooled servers mainly rely on pipelines for cooling. However, this cooling method cannot fully dissipate heat from every corner of the server cabinet, and the pipeline system is very complex. Therefore, immersion liquid-cooled cabinets have emerged. However, during the use of immersion liquid-cooled cabinets, a separate cabinet for liquid replenishment and temperature control is often required. Therefore, it not only increases the floor space of the equipment but also is not conducive to liquid-cooling monitoring inside the server cabinet.

[0005] At the same time, the current immersion liquid-cooled network servers also have the following problems. First, the current immersion servers set up control mechanisms on one side of the cabinet, which not only occupies a large floor space but also is mostly connected by pipelines. The pipelines connect the inner cavity where the server is placed and the refrigeration container. Not only do we need to pay attention to the pipelines during maintenance to avoid pipeline leakage, but also the low circulation efficiency of the coolant results in low heat exchange efficiency. Second, in order to ensure the cooling liquid level and maintain the cooling efficiency, it is necessary to effectively monitor the circulation rate of the coolant. At present, a liquid level gauge is often used to monitor the liquid level, and the detection result is relatively single, making it difficult to reflect the cooling efficiency. Moreover, there is no supervision means on one side of the pipeline, and it is difficult to detect pipeline leakage in time and issue an alarm, which is likely to cause waste of coolant. In view of this, in-depth research on the above problems has led to the generation of this case. Summary of the Invention

Detailed implementation manners

[0053] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0054] Please refer to Figures 1 - 11 , the present invention provides an implementation solution: In the application process of modern network servers, in order to improve the operation efficiency of network servers, ensuring the stability of the external environment of network servers is the most important factor. When a network server is running, since highly integrated electronic and electrical components will generate a large amount of heat, heat dissipation is the most important factor to be considered in the environmental factors of modern network servers;

[0055] Due to the high integration of current network servers, the conventional air-cooled heat dissipation form can no longer meet the usage requirements. More server rooms have introduced the liquid-cooled heat dissipation mode. Compared with the conventional air-cooled heat dissipation method, the liquid-cooled heat dissipation mode has higher heat dissipation efficiency and better heat dissipation effect. For example, the immersion liquid-cooled radiator is a new heat dissipation measure for current network servers.

[0056] In the application process of immersion liquid-cooled servers, at present, the immersion liquid-cooled cabinets mainly adopt a left-right symmetric layout structure. One side is the cabinet, and the other side is the liquid-cooling circulation device. Firstly, it occupies a large area, and there are many connecting pipelines, which are prone to leakage problems. At the same time, the water flow exchange efficiency of the pipelines is limited, affecting the heat dissipation efficiency. Secondly, immersion liquid-cooled servers often only have liquid level detection and cannot truly reflect the cooling effect.

[0057] Embodiment 1: To solve the above problems, the present application discloses a control device applied to a network server environment, including a cabinet 1. The cabinet 1 is a hollow shell with a rectangular structure. A maintenance door 11 is provided at the top of the cabinet 1. Using the cabinet 1 as the external support structure for the server unit 2, a support plate 14 is provided on one side of the cabinet 1, and an operation panel 15 is provided on one side of the support plate 14. Through the operation panel 15, the inside of the cabinet 1 can be controlled, monitoring data can be reflected, and the purpose of human-machine interaction can be achieved.

[0058] The maintenance door 11 is hinged to the opening at the top of the cabinet 1. A visual glass window 13 is provided on the maintenance door 11. Through the maintenance door 11, the situation inside the cabinet 1 can be observed, and at the same time, the server unit 2 inside the cabinet 1 can be repaired by opening the maintenance door 11. The server unit 2 is inserted into the cabinet 1 in a limited plug-in manner. A liquid-cooling unit is provided on the cabinet 1 to immerse the server unit 2 under the coolant, thereby using liquid cooling to cool the server and ensuring the operation efficiency of the server.

[0059] According to the description attached Figure 1 - attached Figure 4 It can be seen that the above cabinet 1 is a hollow shell with a rectangular structure. A plurality of wire insertion ports are distributed around the outer edge of the top of the cabinet 1. The positions of several wire insertion ports correspond to those of several slots 12. The bottom of the cabinet 1 is a base, and two pairs of rollers 17 are provided at the four corners of the base. The upper cabinet 1 is supported by the base, and the whole cabinet 1 can be moved by the rollers 17 on the base. Furthermore, several support brackets 16 are provided on the base to support several server units 2, ensuring the stable posture of several server units 2.

[0060] According to the description attached Figure 1 - attached Figure 4 It can be seen that the above several server units 2 are vertically inserted into the cabinet 1. Several slots 12 corresponding to several server units 2 are provided inside the cabinet 1. Under the limiting action of several slots 12, several server units 2 are ensured to be parallel. Furthermore, the wire insertion ports on the cabinet 1 are connected to the data interfaces of the server units 2 to achieve data transmission connection, facilitating the maintenance and processing of the server units 2.

[0061] According to the description attached 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 wraps around the outside of the cabinet 1. The protective storage structure 3 serves the purpose of wrapping the cabinet 1. The number of protective storage structures 3 arranged on the cabinet 1 is at least three, and the protective storage structure 3 stores insulating coolant. 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. Second, it plays a role in sealing and protecting the inside of the cabinet 1, improving the protection effect inside the cabinet 1 through the wrapping effect. As a circulation space, it can return the coolant for cooling. Finally, the liquid cooling flow rate monitoring structure 4 and the liquid level warning structure 5 are mounted on the protective storage structure 3 and connected to the cabinet 1 and the protective storage structure 3, playing a role in adjusting the cooling efficiency.

[0063] Furthermore, according to the attached drawings of the specification Figure 1 - attached drawings Figure 6 It can be seen that the liquid cooling flow rate monitoring structure 4 pumps the coolant into the cabinet 1 to complete the coolant injection. Under the action of the coolant, several server units 2 are cooled. After the cooling is completed, the coolant flows upward and then returns to the protective storage structure 3 from the liquid level warning structure 5;

[0064] According to the attached drawings of the specification Figure 1 - attached drawings Figure 8 It can be seen that the above-mentioned liquid level warning structure 5 is arranged on the protective storage structure 3. The liquid level warning structure 5 is used to monitor the backflow water flow while the coolant is flowing back. An alarm is triggered when the backflow water flow is lower than the critical value. On the one hand, it monitors whether the coolant circulation is stable, and on the other hand, it plays an alarm role in case of leakage;

[0065] According to the attached drawings of the specification Figure 1 - attached drawings Figure 11 It can be seen that the above-mentioned protective storage structure 3 includes an outer cooling module 31. One side of the outer cooling module 31 is integrally formed with the side wall of the cabinet 1. The outer cooling module 31 serves as the storage space for the equipment coolant and cools the coolant at the same time. A communication port 32 is arranged at the bottom of the outer cooling module 31 and is connected to the inside of the cabinet 1. The communication port 32 serves as the circulation inlet of the cooling medium. A return port 33 is arranged at the top of the outer cooling module 31 and is connected to the liquid level warning structure 5. The return port 33 serves as the circulation return port of the cooling medium.

[0066] According to the attached drawings of the specification Figure 5 - attached drawings Figure 11It can be seen that the above-mentioned external cooling module 31 includes an outer casing 311. The outer casing 311 is a rectangular-structured housing. On the side of the outer casing 311 close to the cabinet 1, there is a coolant storage tank 312. At the bottom of the coolant storage tank 312, there is a liquid outlet 313 connected to the communicating vessel 41. At the top of the coolant storage tank 312, there is a return port 33 connected to the liquid level warning structure 5. On one side of the external cooling module 31, there is an air deflector 314. On the side of the coolant storage tank 312 corresponding to the air deflector 314, there is a cooling plate 3141. The air deflector 314 actively generates air flow to actively cool the cooling plate 3141. The cooling plate 3141 exchanges heat with the coolant storage tank 312 to dissipate the heat of the recycled coolant.

[0067] In the specific implementation process, the outer casing 311 is the supporting structure of the external cooling module 31. The outer casing 311 is integrally formed with the side wall of the cabinet 1. The outer casing 311 is divided into two layers. The inner layer close to the cabinet 1 is the coolant storage tank 312. The coolant storage tank 312 is a closed rectangular box that serves to store the coolant and is closer to the cabinet 1 to facilitate the circulation of the coolant. Specifically, the return port 33 and the liquid outlet 313 provided on the coolant storage tank 312 are respectively connected to the communicating vessel 41 and the liquid level warning structure 5. The circulation of the coolant is realized through the cooperation of the liquid level warning structure 5 and the communicating vessel 41.

[0068] Furthermore, the other layer of the outer casing 311 is the air deflector 314. The air deflector 314 generates cooling air to cool the cooling plate 3141 by air, thereby cooling the coolant located in the coolant storage tank 312. Specifically, the above-mentioned air deflector 314 includes an air flow channel 3142. The air flow channel 3142 is arranged parallel to the coolant storage tank 312 on one side of the outer casing 311. At the top of the air flow channel 3142, there is a gas guiding fan 3143. The cooling plate 3141 is arranged corresponding to the coolant storage tank 312. The cooling plate 3141 is a metal plate with high heat conduction efficiency. A number of cooling fins are arranged in a linear array on the cooling plate 3141 and are located in the air flow channel 3142. At the bottom of the air flow channel 3142, there is a sealing net 3144.

[0069] In 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 guiding fan 3143 flows through the cooling plate 3141. The cooling fins on the cooling plate 3141 increase the contact area and send out heat faster. Then, the cooling plate 3141 absorbs the heat in the coolant storage tank 312 through heat conduction, thereby realizing the cooling of the coolant. In this way, the coolant can be circulated again to cool the server unit 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, but flow into the coolant storage tank 312. And during the circulation process of the coolant, the dependence on pipelines is reduced, the risk of leakage is avoided, and at the same time, the coolant circulation rate can be adjusted more flexibly, 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 needed for assistance.

[0070] According to the attached drawings of the specification Figure 1 - attached drawings Figure 8 It can be seen that the liquid level warning structure 5 disclosed in the present application includes an overflow port 51. The overflow port 51 is arranged at the top of the side wall of the cabinet 1. The return port 33 is communicated with the overflow port 51. The overflow port 51 is arranged on the inner side wall surface of the cabinet 1. The overflow port 51 is higher than the top of the server unit 2 in the cabinet 1. In this way, it can be ensured that the coolant completely submerges the server unit 2. Then, a liquid flow detector 52 is arranged 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-shaped through groove. A filter screen 53 is arranged 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 outer cooling module 31 through the overflow port 51;

[0071] Furthermore, according to the attached drawings of the specification Figure 1 - attached drawings Figure 8 It can be seen that the above-mentioned return port 33 is a flared groove with an enlarged inlet end, and its cross-sectional dimension is smaller than that of the overflow port 51. The return port 33 plays a role in collecting the flow, 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 an installation port 521. The installation port 521 is arranged at the top of the outer cooling module. An installation plate 522 is connected to the installation port 521 by threads. A extension rod 523 is arranged at the bottom of the installation plate 522. The extension rod 523 extends into the overflow port 51. A photoelectric detection probe 524 is arranged on the extension rod 523. The photoelectric detection probe 524 is a reflection type photoelectric detection probe 524. A reflecting mirror 525 is correspondingly arranged below the installation port 521. A transmitting light source 526 is arranged on the photoelectric detection probe 524. A long strip-shaped receiver 527 is arranged corresponding to the transmitting light source 526;

[0072] In the specific implementation process, the installation port 521 serves as the installation space for the photoelectric detector. The detection end of the photoelectric detector faces towards the inside of the detection port. The photoelectric detector is separately arranged on the installation port 521 through the mounting plate 522. Through the extension rod 523 as an extension, the photoelectric detection probe 524 extends into the detection port. The photoelectric detection probe 524 works on the principle of reflection detection. A reflecting mirror 525 is arranged at the lower part of the installation port 521. The emission light source 526 of the photoelectric detection probe 524 emits a detection beam, and the beam irradiated on the reflecting mirror 525 will return to the receiver 527. A number of photosensitive elements arranged in a matrix are provided on the receiver 527. Since the overflow tank drains the water flowing back in the cabinet 1 from the return tank back to the external cooling module 31, when the water level changes, due to the change in the water level depth, the refraction angle of the beam emitted by the emission light source 526 changes. When the beam is reflected to the receiver 527, the beam will irradiate at different positions of the receiver 527 due to the change in the refraction angle. The depth of the backflow water level is judged according to the received position data of the receiver 527, so as to judge the water level data of the backflow.

[0073] According to the attached drawings of the specification Figure 1 - attached drawings Figure 6 As can be seen, the above liquid cooling flow rate monitoring structure 4 includes a communicating vessel 41. One side of the communicating vessel 41 is communicated with the bottom of the external cooling module 31, and the other side of the communicating vessel 41 is communicated with the communication port 32. A liquid flow monitoring component 42 is installed on the communicating vessel 41. The liquid flow monitoring component 42 is used to monitor the coolant flow rate between the protection storage structure 3 and the cabinet 1. A water flow driving component 43 is arranged on the communicating vessel 41. The water flow driving component 43 is used to control the liquid flow circulation rate;

[0074] In the specific implementation process, the communicating vessel 41 extends from the bottom of the external cooling module 31 and serves as the installation space for the liquid cooling flow rate monitoring structure 4. The communicating vessel 41 is a cavity shell with an L-shaped cross-section with rounded corners. A pair of closed grooves 431 are arranged at both ends of the communicating vessel 41. The pair of closed grooves 431 are respectively communicated with the communication port 32 and the liquid outlet 313, playing the role of communicating the external cooling module 31 and the cabinet 1. At the same time, the entire liquid cooling flow rate monitoring structure 4 is protruded, which is convenient for maintaining and overhauling the liquid cooling flow rate monitoring structure 4. The communicating vessel 41 is communicated with the liquid outlet 313 at the bottom of the external cooling module 31, so that the cooled water flows back into the cabinet 1 through the water flow driving component 43. According to the operating temperature of the server, the working frequency and power of the water flow driving component 43 are controlled to change the rate of the water flow cycle, improve the heat dissipation efficiency, and detect the water flow rate through the liquid flow monitoring component 42 as a feedback signal to monitor the water flow cycle rate.

[0075] According to the attached drawings of the specification Figure 1 - attached drawings Figure 11It can be seen that the above-mentioned liquid flow monitoring component 42 includes a liquid flow monitoring groove 421. The communicating vessel 41 is provided with a liquid flow monitoring groove 421. A swirl flow velocity detector is installed on the liquid flow monitoring groove 421, and the swirl flow velocity detector monitors the flow velocity of the liquid flowing through the liquid flow monitoring groove 421.

[0076] Specifically, the above-mentioned swirl flow velocity detector includes a detection frame 422. The detection frame 422 is installed on the liquid flow monitoring groove 421. A detection ring groove 423 is provided on the detection frame 422. A detection impeller 424 is assembled in the detection ring groove 423. The outer part of the wheel shaft of the detection impeller 424 is sleeved on a star-shaped detection seat 425. A number of detection magnets 426 are provided at the tips of the star-shaped detection seat 425. A detection housing is provided on one side of the detection ring groove 423. 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. Using the detection frame 422 as the support main body, a detection ring groove 423 is fixedly provided at the bottom of the detection frame 422. 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, so that the detection impeller 424 rotates. Furthermore, the detection impeller 424 drives the star-shaped detection seat 425 to rotate. Since a number of detection magnets 426 on the star-shaped detection seat 425 approach the Hall sensor 427 periodically during the rotation process, the magnetic force acting 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 velocity. Specifically, when the change frequency is relatively high, it proves that the rotation speed of the detection impeller 424 is relatively fast, and at this time the liquid flow velocity is relatively high. Through this magnetic force detection device built in the liquid flow channel, it is possible to accurately express the circulation rate of the coolant even without using a pipeline for liquid flow measurement, so as to conveniently measure the liquid flow exchange efficiency between the cabinet 1 and the external cooling module 31 and more accurately control the cooling rate.

[0078] According to the instruction manual appendix Figure 1 - appendix Figure 11 It can be seen that the above-mentioned water flow driving component 43 includes a driving motor 432. The driving motor 432 is arranged on one side of the communicating vessel 41. A water deflecting roller 433 is arranged on one side of the communicating vessel 41. A driving shaft 434 is provided in the middle axis of the water deflecting roller 433. The driving shaft 434 penetrates through one side of the communicating vessel 41 and is sealed with a sealing gasket. The driving end of the driving motor 432 is connected with a gearbox 435, and the gearbox 435 is connected with the driving shaft 434.

[0079] During the specific implementation process, the water flow driving 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 plurality 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 by the multi-stage reduction of the gear box 435, thereby increasing the output torque on one side of the water-pumping roller 433.
