Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of switch cabinets, in particular to a combined switch cabinet for data centers. BACKGROUND

[0002] In today's digital era, data has become a key production factor driving social development and enterprise operation. As a physical carrier for centralized processing, storage, transmission and management of massive data, data centers constitute the core infrastructure of cutting-edge technologies such as the Internet, cloud computing, big data and artificial intelligence.

[0003] In the power supply and distribution system of a data center, a switch cabinet plays a crucial role as the "nerve center" and "security guard". It undertakes functions such as reception, distribution, control, protection and monitoring of electric energy. According to the authorized publication number "CN116111461A", a combined switch cabinet is disclosed. The present application comprises a switch cabinet body, the bottom end of which is fixedly connected with a fixed support column, the surface of which is fixedly connected with a connecting positioning block, the inside of which is movably connected with a positioning bolt, and the front surface of which is movably connected with a movable switch door. The fixed connection frame, connecting plug and connecting limiting mechanism provided in the present application facilitate the preliminary connection and fixation of adjacent switch cabinet bodies by clamping the inside of the connecting plug through the fixed connection frame, followed by the connection between the positioning bolt and the ground to reinforce the connecting positioning block, fixed support column and switch cabinet body, and then the adjustment of the connecting limiting mechanism to quickly limit and reinforce the adjacent switch cabinet bodies, making the operation convenient.

[0004] In order to meet the needs of flexible expansion and standardized deployment of data centers, combined switch cabinets have emerged and been widely used. Currently, when multiple switch cabinets are combined for use, the connecting parts between adjacent cabinet bodies are mostly connected and fixed by screws or angle steels. The assembly is relatively cumbersome, and when a single cabinet body is separated and recycled, if the screws slip due to long-term use, it will bring a lot of trouble to the disassembly process.

[0005] Secondly, most conventional switch cabinets and combined switch cabinets lack the ability to actively control the internal micro-environment, especially temperature and humidity, in their design. Long-term high temperature can accelerate the aging of insulating materials, reduce the performance and lifespan of components, and even cause fires. When the ambient temperature changes dramatically or the humidity is high, the internal temperature of the switch cabinet may be lower than the dew point temperature, causing water vapor to condense into water droplets on the metal surface and electrical components. Condensation can severely reduce electrical insulation strength, cause the creepage distance to be shortened, and cause short circuits, flashovers and even breakdown accidents, posing a fatal threat to equipment safety.

[0006] At the same time, although most switch cabinets are provided with sensing devices for sensing temperature and humidity, the sensing installation positions of the sensing devices are basically single-point settings, which can only locally sense and can easily result in low sensing accuracy, so further improvement is needed to enable the detection of temperature and humidity in the micro environment of the switch cabinet to have a comparative sensing effect to improve the accuracy of temperature and humidity control operation.

[0032] Embodiment two The system process based on the same cabinet body and the two symmetrically arranged sensors for environmental monitoring and triggering corresponding control is as follows: S1, system initialization and sensor calibration Start the main control module 24, and the processing chip is powered on for self-checking to ensure that the temperature sensor 303 and the humidity sensor 304 are in normal communication; The two temperature sensors 303 and the two humidity sensors 304 symmetrically arranged in the same cabinet body 12 are calibrated for initial values to ensure that the detection error is within the allowable range; S2, real-time monitoring of environmental parameters The temperature sensor 303 and the humidity sensor 304 continuously collect the temperature and humidity data inside the cabinet body 12 and transmit the data to the processing chip of the main control module 24 in real time; The processing chip synchronously compares the sensor data of the two symmetric positions in the same cabinet body and calculates the difference between them; S3, error analysis and threshold judgment The processing chip compares the error value of the sensor data with the preset comparison threshold value: If the error value of the temperature or humidity is less than or equal to the set threshold value, it is determined to be normal fluctuation, and no device action is triggered, and the system continues to monitor; If the error value of the temperature or humidity is greater than the set threshold value, it is determined to be an abnormal state, and the device control process is entered; S4, abnormal state classification and device control High temperature environment - error exceeds threshold value and average temperature is too high: The processing chip starts the fan 23 and simultaneously starts the water pump 20005. The airflow is cooled through the cold water pipe 20001 and the cooling fins 20003, and the low-temperature airflow is delivered into the cabinet 12. High humidity environment - error exceeds threshold and average humidity is too high: The processing chip starts the fan 23 and simultaneously starts the electric heating tube 2005, which heats the airflow through the heat-conducting fins 2003 and delivers dry hot airflow into the cabinet 12. High humidity and low temperature environment - error exceeds the threshold and humidity is high while temperature is low: The processing chip activates the fan 23 and the heating element 2005 to deliver hot airflow to increase the temperature and reduce the humidity; High humidity and high temperature environment - error exceeds the threshold and both humidity and temperature are high: The processing chip starts the fan 23 and water pump 20005 to deliver low-temperature airflow for priority cooling, and at the same time determines whether the electric heating element 2005 needs to be started intermittently based on the humidity. Simple low temperature environment - error exceeds threshold and temperature is too low: The processing chip activates the fan 23 and the heating element 2005 to deliver hot airflow to increase the temperature inside the cabinet. S5. Operation Status Feedback and Adjustment During equipment operation, the sensors continuously monitor environmental parameters, and the processing chip dynamically adjusts the operating status of the fan 23, electric heating tube 2005 or water pump 20005 based on real-time data until the sensor data returns to normal and the error value is below the threshold. If the parameters do not improve after the equipment has been running for a long time, the main control module 24 sends an alarm message to the monitoring center via a wireless transceiver. Example 3 Application Project: Intelligent Control System for Data Center Environment I. Scene Setting In a large data center server room, there are multiple modular switch cabinets. Each switch cabinet is equipped with power distribution control components, circuit breakers, current / voltage display panels and other equipment. The server room environment is complex and has seasonal temperature and humidity fluctuations as well as high temperature and high humidity problems caused by long-term operation of equipment. II. System Composition and Deployment Cabinet assembly 1: Multiple cabinet bodies 12 are installed side by side on the base 10 and isolated by partition plates 11 to prevent static electricity and short circuits; Hot and cold airflow conveying component 2: The main pipe 21 connects to all branch pipes 30, and the fan 23 is responsible for airflow delivery; A dustproof net 27 is installed inside the storage tube 25 to prevent dust from entering; The heating element 2005 and the cold water pipe 20001 are responsible for heating and cooling the airflow, respectively. Airflow delivery and monitoring assembly 3: Each cabinet body 12 is equipped with a flow divider 33 and air nozzle 34 to ensure uniform airflow distribution. Temperature sensor 303 and humidity sensor 304 monitor the cabinet environment in real time III. Intelligent control process 1. Normal operation - normal temperature and humidity Temperature sensor 303 and humidity sensor 304 detect that the cabinet environment is within the set threshold, such as temperature 20-25℃, humidity 40%-60%; The main control module 24 processing chip determines that there is no need to start heating or cooling, only the fan 23 is started for regular ventilation to maintain airflow circulation; 2. High temperature environment treatment - summer or high load equipment The sensor detects that the cabinet temperature exceeds 30℃; The main control module 24 starts the fan 23, and at the same time starts the water pump 20005, and circulates cold water through the cold water pipe 20001 and the cooling fin 20003; The airflow is cooled to form a low-temperature airflow, which is sent into the cabinet through the branch pipe 30 and the air nozzle 34 to achieve cooling; 3. High humidity environment treatment - plum rain season or humid area The sensor detects that the cabinet humidity exceeds 70%; The main control module 24 starts the fan 23, and at the same time starts the electric heating pipe 2005, which heats the airflow through the heat-conducting fin 2003; Dry hot airflow is sent into the cabinet to reduce humidity and prevent electrical components from being damp; 4. Low temperature environment treatment - winter or cold area The sensor detects that the cabinet temperature is lower than 10℃; The main control module 24 starts the fan 23 and electric heating pipe 2005 to deliver hot airflow to prevent electrical components from being stiffened due to low temperature; 5. High humidity and high temperature occur at the same time The main control module 24 prioritizes starting the water pump 20005 for cooling, and determines whether to start the electric heating pipe 2005 according to the humidity, usually prioritizing cooling.

[0033] In specific implementation: the base 10 of the scheme is used as a basic platform, a plurality of partition plates 11 are fixed on the base 10 through screws, the cabinet body 12 is erected on the base 10 and is staggered with the partition plates 11, and the design makes the partition plates 11 effectively isolate the adjacent cabinet bodies 12 and prevent static electricity caused by direct contact. The base 10 and the partition plates 11 adopt a composite structure of metal lining and insulating outer layer, so as to fundamentally eliminate the risk of conduction between the cabinet bodies 12. In order to further improve the overall stability of the plurality of cabinet bodies 12 combined side by side, the system is provided with a back plate 16 on one side of the base 10, which is used to limit the longitudinal displacement of the cabinet body 12. The gas cylinder 17 installed on the upper end of the back plate 16 will drive the cover plate 18 to press tightly on the upper surfaces of all the cabinet bodies 12 when the piston rod of the gas cylinder 17 is retracted. The alignment block 19 at the bottom of the cover plate 18 is accurately inserted into the alignment seat 110 at the upper end of the corresponding cabinet body 12, so as to form a tight plug-in fixing. The self-top-to-bottom pressing and positioning mechanism ensures the rigid connection of the entire switch cabinet array in the physical structure and the reliability in long-term operation. The switch cabinet has intelligent environment monitoring and response capability, which is mainly realized by the airflow conveying and monitoring assembly 3 and the main control module 24. In the inside of each cabinet body 12, the temperature sensor 303 and the humidity sensor 304 are symmetrically installed on the sensor seat 302 fixed by the connecting rod 301. The two sensors continuously monitor the environmental parameters in the cabinet, and the collected data is transmitted to the processing chip in the main control module 24 for analysis. The comparison threshold is preset in the processing chip. When the reading error of the two symmetric sensors exceeds the threshold, or the sensor reading as a whole indicates that the environment is abnormal, such as high temperature, high humidity or low temperature, the processing chip will issue a command to start the fan 23 to generate airflow. At the same time, the processing chip will make intelligent decisions according to the specific environmental conditions. If high humidity is detected, the electric heating pipe 2005 will be started to heat the airflow to reduce the humidity, regardless of the temperature. If high temperature is detected, the water pump 20005 will be started to drive the cold water to circulate in the cold water pipe 20001 to cool the airflow. If it is only low temperature, the electric heating pipe 2005 will be started to heat the airflow to ensure that the electrical components work at an appropriate temperature. This system realizes accurate perception and self-adaptive temperature and humidity adjustment of the micro-environment in the cabinet. The core driving component is the fan 23 which inhales air from the dustproof net 27 on the side of the storage cylinder 25. When hot air is needed, the power seat 2004 connected with the main control module 24 supplies power to the electric heating tube 2005 which is in the form of U and penetrates through the heat insulation sleeve 2002 in the transition interface 2001. The multiple heat conduction fins 2003 on the surface of the electric heating tube 2005 greatly increase the contact area with the flowing air, and efficiently heat the air flow into dry hot air. When cold air is needed, the main control module 24 starts the water pump 20005 to pump external cold water into the U-shaped cold water pipe 20001 which penetrates through the transition interface 2001. The multiple cooling fins 20003 densely distributed on the surface of the cold water pipe 20001 also expand the heat exchange area, so that the flowing air is fully cooled. Finally, the air flow after temperature and humidity adjustment is sent into the main pipeline 21 through the air outlet of the fan 23 and the sealing sleeve 20002 on the upper end of the transition interface 2001. The heat insulation sleeve 2002 and the sealing sleeve 20002 ensure that the cold and hot components work safely and efficiently in parallel in a small space without interfering with each other. The air flow after temperature and humidity adjustment is uniformly delivered to each cabinet body 12 through a set of efficient distribution system. The air flow first enters the central main pipeline 21 above the cover plate 18. The main pipeline 21 is connected with multiple vertical branch pipelines 30 which penetrate through the cover plate 18 by welding. Each branch pipeline 30 corresponds to a cabinet body 12. The lower end of the branch pipeline 30 is connected to a flow distributor 33 through a pipeline interface 32. After the air flow enters the inner cavity of the flow distributor 33 through the pipeline interface 32, it is again distributed by multiple air nozzles 34 which are equally distributed in a ring shape at the lower end of the flow distributor 33, forming multiple fine air flows, so as to ensure that the dry or cooled air can be evenly and fully diffused in the cabinet body 12, avoiding air flow dead angles. In terms of maintenance, the system is also designed with a convenient disassembly structure. For example, when the dustproof net 27 needs to be cleaned regularly, the screw cap 211 can be unscrewed to separate it from the threaded column 210, so as to take out the frame 26 with the dustproof net 27 from the storage cylinder 25. Similarly, when the flow distributor 33 and the sensor need to be repaired or cleaned, the positioning pins 3003 on the positioning frames 3001 on both sides of the branch pipeline 30 can be pulled outwards at the same time, compressing the springs 3004 to make the positioning pins 3003 come out of the positioning seats 3005 of the pipeline interfaces 32, so as to separate the entire flow distributor 33 assembly from the branch pipeline 30, greatly simplifying the maintenance process.
