Description

Technical Field

[0001] The present invention relates to the technical field of heat dissipation and cooling devices for data centers, and in particular to a safe and reliable cold channel for a computer room in a data center. Background Art

[0002] Cold aisle design is a common airflow management solution in data centers, mainly used to optimize equipment heat dissipation and reduce energy consumption. It separates the cold air supply channel and hot air exhaust channel of the server cabinet to improve cooling efficiency. It mainly solves the problem of cold and hot air mixing and improves the cooling efficiency of the air conditioning system.

[0003] Traditional cold aisles usually have the following two configurations: open cold aisles, where both ends of the cold aisle may be open without closed doors, which in some cases can cause cold air leakage and reduce cooling efficiency; closed cold aisles, which are usually equipped with transparent ceilings or sliding doors to enclose the cold aisle, thereby better maintaining a centralized supply of cold air and further improving cooling efficiency and energy saving.

[0004] The cold aisles formed by the above two configurations will have the following disadvantages: Risk of mixing of cold and hot air. Although the separation design of cold aisles and hot aisles improves the cooling effect, cold air and hot air may still mix in the absence of complete closure, reducing system efficiency; Limited safety management. In the traditional cold aisle design, the control of entering the cold aisle is relatively loose, and there is a lack of effective control over the entry and exit of personnel. Unauthorized personnel may enter the cold aisle area, especially when operating near sensitive equipment, which poses a safety hazard; Low firefighting efficiency. For closed cold aisles, once a fire occurs, the closed ceiling design causes the firefighting system to be unable to operate efficiently, and the gas will fill the entire cold aisle in a short time, greatly reducing the firefighting efficiency; The channel door is often open, which reduces the cooling efficiency. Due to daily construction and maintenance work, construction personnel or maintenance personnel often need to enter the cold aisle, which is prone to the channel door being often open. When there are many people entering and leaving, it is often easy for them to forget to close the door. In this way, the closure of the cold aisle cannot be guaranteed in time, and the cooling efficiency is also reduced; The lighting is always open, which leads to an increase in electricity costs. The lighting systems of many data centers are manually operated and often remain open for a long time, resulting in energy waste. Especially at night or when no one is operating, the lighting is turned on continuously, wasting electricity; the lighting system cannot switch according to the scene. The existing lighting system is usually a single mode and does not have the function of adjusting brightness or switching modes according to the needs of different operating scenarios (such as inspection or maintenance). Summary of the invention

[0005] The purpose of the present invention is to provide a safe and reliable cold channel in a data center computer room. On the basis of the traditional cold channel, it adds functions such as access control system, fire linkage skylight system, specially designed channel door system, optimized intelligent lighting system and intelligent control, so as to achieve a comprehensive improvement in personnel management, equipment safety, emergency response and system operation and maintenance in the cold channel; it can effectively improve the safety and intelligent management level of the cold channel, optimize the utilization efficiency of the cold source, improve the convenience of operation, and ensure the safe response capability of the data center in emergency situations.

[0050] Please refer to the attached Figure 1-7 An example is given to describe a safe and reliable cold channel in a data center computer room provided by the present invention.

[0051] The main vertical frame 201 in the vertical frame member 2 is symmetrically fixed on one side of the top of the bottom plate member 1, and the opposite vertical frame 202 is symmetrically fixed on the other side of the top of the bottom plate member 1. Data center cabinets 3 are arranged between the top of the bottom plate member 1 and the main vertical frame 201 and between the top of the bottom plate member 1 and the opposite vertical frame 202. A cold channel can be formed between the oppositely distributed data center cabinets 3;

[0052] The top of the vertical frame member 2 and the data center cabinet 3 are overlapped and arranged with a fire linkage skylight system 4. The bottom long frame 401 and the bottom short frame 402 in the fire linkage skylight system 4 are connected to form a quadrilateral frame. The two sides of the outer middle part of the rotating frame 403 are connected to the middle part of the main body of the bottom short frame 402 through a rotating shaft 405. The outer end of one group of rotating shafts 405 is fixedly connected to an axis connecting piece 406. The inner top end of one group of bottom short frames 402 is provided with an automatically sliding stand 410. The sliding column 411 is horizontally fixed to the top of the stand 410 and is slidably connected to the axis connecting piece 406, which can form an automatic opening and closing action of the rotating frame 403;

[0053] A passage door system 6 is installed on the outer sides of the main vertical frame 201 and the opposite vertical frame 202 on the same side. The passage door system 6 includes a door frame 601 and a door leaf 602. The door frame 601 is fixedly installed on the outer side surfaces of the main vertical frame 201 and the opposite vertical frame 202. The door leaves 602 are hinged in pairs in the door frame 601 and can be opened and closed automatically.

[0054] The specific structure of the bottom plate member 1 and the frame member 2 is as follows: Figure 2 As shown, the antistatic floor 101 is laid in the machine room to eliminate static electricity. A cold air channel 102 can be formed between the outer bottom surface of the antistatic floor 101 and the bottom surface of the machine room and connected to the air outlet of the refrigeration air conditioner;

[0055] The main vertical frame 201 is symmetrically fixed on one side of the antistatic floor 101 which is laid into a plane, and the opposite vertical frame 202 is symmetrically fixed on the other side of the antistatic floor 101 which is laid into a plane;

[0056] And if necessary, each set of main frames 201 can be filled with foam to improve the heat insulation effect.

[0057] The specific installation position structure diagram of the data center cabinet 3 is as follows Figure 3 As shown, the outer side of each cabinet body 301 is connected with a heat dissipation hole 302, and the cabinet body 301 can be used to install servers, switches and router lighting equipment, and the heat dissipation holes 302 are used to achieve heat dissipation of the internal equipment of the cabinet body 301;

[0058] In addition, cold air outlets 103 are symmetrically provided in the main body of the antistatic floor 101 , and the refrigeration air conditioner can deliver cold air to the cold channel through the cold air channel 102 and the cold air outlets 103 .

[0059] A monitoring sensor system 9 is also installed on the inner side of the cabinet body 301. The monitoring sensor system 9 includes a temperature and humidity sensor 901 and a smoke sensor 902, which can collect environmental data in the cold channel in real time, and sensors with other functions can be added when necessary.

[0060] A display control center 7 is installed outside one of the main vertical frames 201. The display control center 7 is composed of a display screen, an embedded PLC and an end effector. The embedded PLC is the core control device of the cold channel system, responsible for collecting, processing and responding to signals from various sensors, actuators and other intelligent devices, and monitoring the cooling environment, safety status and equipment operation status in the cold channel;

[0061] At the same time, the embedded PLC can control the equipment in the cold channel by writing control logic programs.

[0062] The outer bottom surface of the bottom short frame 402 is also equipped with an intelligent lighting system 5, an energy-saving lamp 501 is installed on the outer bottom surface of the bottom short frame 402, a mechanical switch 503 is installed on the outer side of the door frame 601, and the energy-saving lamp 501 can be turned on manually. The induction switch 502 is installed on the inner side of the door frame 601. In daily inspection scenes, the energy-saving lamp 501 is automatically controlled by the induction switch 502, and the duration of the induction switch 502 can be set, generally set to 60 seconds. The intelligent lighting system 5 can be turned on or off according to the personnel entering or leaving the cold channel, thereby achieving energy-saving effects;

[0063] And in the event of equipment maintenance or emergency, the intelligent lighting system 5 can automatically switch to the normally on mode to provide continuous high-brightness lighting to ensure that the staff can get sufficient light during long-term operation;

[0064] The intelligent lighting system 5 can also be remotely controlled and adjusted through the data center security system to meet the needs of different brightness and usage time.

[0065] The specific structure of the fire linkage skylight system 4 is as follows Figure 4 and Figure 5 As shown, the fire linkage skylight system 4 is fixedly installed in the plane composed of the main vertical frame 201, the opposite vertical frame 202 and the cabinet body 301 through a quadrilateral frame structure arrangement composed of a bottom long frame 401 and a bottom short frame 402. A rotating shaft sleeve 404 is fixedly installed in the middle of the inner end of each group of bottom short frames 402, and a rotating shaft 405 is fixedly connected to the middle of the outer side of the rotating frame 403. The rotating shaft 405 on the same side is rotatably connected in the rotating shaft sleeve 404, and a double-layer laminated glass is fixedly connected to the inner middle of the rotating frame 403. A sealing strip is installed on the outside of the rotating frame 403 to improve the sealing and heat insulation effect;

[0066] A push slot 407 is provided in the main body of the shaft connecting member 406, and a sliding column 411 is slidably connected in the push slot 407;

[0067] The bottom slide 408 is fixedly connected to the inner bottom surface of one group of bottom short frames 402, the bottom slider 409 is slidably connected in the bottom slide 408, and the stand 410 is fixedly connected to the top of the bottom slider 409. The inner bottom surface of the group of bottom short frames 402 is also fixedly installed with a telescopic electric cylinder 412, and the outer end of the telescopic rod of the telescopic electric cylinder 412 is fixedly connected to the bottom slider 409. By starting the telescopic electric cylinder 412, the telescopic rod of the telescopic electric cylinder 412 drives the bottom slider 409 to move along the bottom slide 408 with high precision, so that the sliding column 411 and the pushing slide groove 407 can form a sliding fit, thereby driving the shaft connection 406 to rotate within a certain range, so that the rotating shaft 405 rotates, forming an opening and closing action of the rotating frame 403;

[0068] The rotating frame 403 is controlled within an opening angle range of 30 degrees, which will not affect the opening effect and can also reduce the restoring force of the rotating frame 403 from the open state to the closed state;

[0069] A magnetic lock 413 is installed between the bottom surface of one of the bottom long frames 401 and the outer side surface of the rotating frame 403. The magnetic lock 413 is composed of an electrically controlled magnet and an iron sheet, and can lock the rotating frame 403 after the rotating frame 403 is closed in place.

[0070] At the same time, the fire linkage skylight system 4 can also be linked with the smoke sensor 902. After the display control center 7 receives the fire alarm signal sent by the smoke sensor 902, it can automatically start the bottom short frame 402 and disconnect the magnetic lock 413, so that the rotating frame 403 can be opened.

[0071] The specific structure of the channel door system 6 is as follows: Figure 6 As shown, the door leaf 602 is hinged to the door frame 601 through a damping hinge 604, and due to the damping effect of the damping hinge 604 itself, the door leaf 602 can be closed slowly;

[0072] An automatic door closer 603 is installed between the outer upper end of the door leaf 602 and the door frame 601. Driven by the automatic door closer 603, the door leaf 602 can not only be opened and closed automatically, but also be opened to a set angle to meet the needs of operators to enter and exit the equipment.

[0073] The door leaf 602 is also equipped with double-layer laminated glass, and a sealing strip is provided between the door leaf 602 and the door frame 601, which can effectively prevent the leakage of cold air and ensure the efficient isolation of cold and hot air.

[0074] The infrared sensor 605 is installed on the outer side of the top of the door frame 601 and will not interfere with the opening and closing of the door leaf 602. The infrared sensor 605 can sense the space below and cooperate to form the slow closing effect of the door leaf 602. When the door leaf 602 is open, the infrared sensor 605 senses that there is no object moving below and after a delay of 10 to 15 seconds, it can send a signal to the display control center 7 to control the automatic door closer 603 to close the door leaf 602, thereby avoiding safety hazards caused by the door leaf 602 closing too quickly, and also avoiding the door leaf 602 being often open due to people entering and leaving forgetting to close it, thereby ensuring the cooling efficiency of the cold channel to the greatest extent.

[0075] The outer side of the door frame 601 is also equipped with an access control system 8, which includes an RFID reader 801 and a facial recognition camera 802. By combining the RFID reader 801 and the facial recognition camera 802, it can ensure that only authorized personnel can enter the cold channel, and an alarm will be triggered if an unauthorized person swipes a card or scans his face more than three times;

[0076] The access control system 8 can be linked with the data center security system through the display control center 7 to record the entry and exit of personnel in real time, and can achieve remote management through the control interface of the data center security system, such as the control of the normally open and normally closed state of the door leaf 602 and the opening and closing control of the energy-saving lamp 501;

[0077] In addition, the access control system 8 can also be linked with the smoke sensor 902 to form an emergency unlocking function. In emergency situations such as fire, the access control system 8 can automatically start the automatic door closer 603, so that the door leaf 602 is automatically opened to facilitate emergency escape.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
