Description

Technical Field

[0001] The present invention belongs to the technical field of communication integrated equipment, and in particular relates to an air duct structure, a micromodule machine room and a micromodule control method. Background Art

[0002] With the development of communication technology, the 5G market, network broadband market and business volume continue to grow, the power consumption capacity of 5G equipment is growing exponentially, and the power consumption cost is also growing exponentially. The micro-module data center integrates the power distribution, air conditioning, backup power, wiring, cabinets, fire protection, monitoring, lighting and other systems of the traditional computer room into one, realizing the rapid and flexible deployment of the system, which can not only reduce the construction cycle of 5G, but also better adapt to the changes of cloud computing, virtualization, centralization, high-density and other servers, improve the operational efficiency of the data center, reduce energy consumption, and achieve rapid expansion.

[0003] In micro-module data centers or other closed systems, unreasonable airflow organization can lead to large temperature differences in the air inlet to cabinet equipment, resulting in the phenomenon that the cold air from the air conditioner does not enter the equipment and directly flows back to the air conditioner without cooling the equipment. Irrational airflow organization can also lead to large temperature differences in the air inlet to the energy storage lithium battery in the micro-module, resulting in inconsistent pressure differences in the energy storage lithium battery, which seriously affects the battery charging and discharging performance and life.

[0004] In current micro-module data centers, communication equipment is generally placed in a centralized manner or cooled and cooled. One is to place the inter-row air conditioner and the equipment cabinet in parallel, and the other is to place the rack-mounted air conditioner and communication equipment in the equipment cabinet. Regardless of which method is used, the following problems still exist in the micro-module:

[0005] (1) Neither row air conditioners nor rack-mounted air conditioners can provide precise air supply. Equipment close to the air conditioner has a large air volume and low inlet air temperature, while equipment far from the air conditioner has a small air volume and high temperature. The temperature difference is often as high as 8°C or more.

[0006] (2) Each equipment cabinet in a micro-module data center has different power and air volume requirements. The traditional micro-module air supply system can only send cold air to the micro-module cold zone. Each equipment cabinet then draws cold air from the micro-module cold zone. It is impossible to cool the equipment in each equipment cabinet on demand. It will also cause cross-wind and turbulence in the entire cold zone, which is prone to hot spot concentration and heat island effect.

[0007] (3) The communication equipment in the micromodule data center has a large inlet temperature difference and concentrated hot spots. The air conditioning wastes air supply, resulting in high energy consumption and inconsistent pressure differences for the energy storage lithium batteries in the micromodule, which seriously affects the charging and discharging performance and battery life of the lithium batteries.

[0008] (4) It is difficult to maintain a balanced wind pressure in a data center room or micromodule static pressure box. Changes in the air supply volume of the air conditioner will also cause corresponding changes in the wind pressure balance of the static pressure box.

[0009] Therefore, neither the first method nor the second method of heat exchange can accurately supply air to the equipment in the micromodule, resulting in a large temperature difference in the air supply between the equipment. Summary of the invention

[0043] like Figures 1 to 6 As shown, an embodiment of the present invention provides an air duct structure 2, including a main frame 21, a static pressure channel and a plurality of damping plates 24. The main frame 21 is arranged on the top of the cabinet group, an air inlet 25 and a plurality of air outlets are arranged on the main frame 21, the static pressure channel is arranged on the main frame 21, the air flow enters the static pressure channel through the air inlet 25, and flows out of the static pressure channel through the plurality of air outlets, each of the air outlets is arranged one by one above a single cabinet 42, and the cabinet 42 is cooled.

[0044] The plurality of damping plates 24 are arranged at intervals along the extension direction of the static pressure channel, and the damping plates 24 are movably connected to the main frame 21. The damping plates 24 can be raised and lowered in the vertical direction so that the pressure difference between each air outlet and the air inlet 25 is within a preset pressure difference range.

[0045] After the air flow enters the static pressure channel from the air inlet 25, the distances between each air outlet and the air inlet 25 along the static pressure channel are different, making it difficult to maintain a balanced wind pressure in the static pressure channel.

The first sealing plate 214 and the second sealing plate 215 are located above the cold air channel 5 to close the cold air channel 5 .

[0056] In one embodiment, the static pressure channel includes a first static pressure channel 22 and a second static pressure channel 23, the first vertical plate 211, the second vertical plate 212, the first sealing plate 214 and the third sealing plate 216 form the first static pressure channel 22, the second vertical plate 212, the third vertical plate 213, the second sealing plate 215 and the third sealing plate 216 form the second static pressure channel 23.

[0057] like Figure 5 As shown, the first static pressure channel 22 is arranged above the first cabinet group 3, the top surface of the first cabinet group 3 and the first sealing plate 214 are arranged in parallel between the first vertical plate 211 and the second vertical plate 212, the top surface of the first cabinet group 3 and the first sealing plate 214 jointly form the bottom surface of the first static pressure channel 22, the inter-row air conditioner 41 of the first cabinet group 3 is the air inlet 25 of the first static pressure channel 22 at the corresponding position of the main skeleton 21, and the multiple air outlets of the first static pressure channel 22 are arranged on the first sealing plate 214, and the number of the air outlets of the first static pressure channel 22 is determined according to the number of cabinets 42 in the first cabinet group 3.

[0058] The second static pressure channel 23 is arranged above the second cabinet group 4, and the top surface of the second cabinet group 4 and the second cover plate 215 are arranged in parallel between the second vertical plate 212 and the third vertical plate 213. The top surface of the second cabinet group 4 and the second cover plate 215 jointly form the bottom surface of the second static pressure channel 23. The inter-row air conditioner 41 of the second cabinet group 4 is the air inlet 25 of the second static pressure channel 23 at the corresponding position of the main skeleton 21. The multiple air outlets of the second static pressure channel 23 are arranged on the second cover plate 215. The number of the air outlets of the second static pressure channel 23 is determined according to the number of cabinets 42 in the second cabinet group 4. In this embodiment, the number of the air outlets is consistent with the number of cabinets 42.

[0059] In another embodiment not shown in the figure, the width of the first sealing plate 214 is equal to the distance between the first vertical plate 211 and the second vertical plate 212, the air inlet 25 and the air outlet of the first static pressure channel 22 are both arranged on the first sealing plate 214, and the inter-row air conditioner 41 of the first cabinet group 3 opens at the corresponding position of the first sealing plate 214 to form the air inlet 25 of the first static pressure channel 22. The width of the second sealing plate 215 is equal to the distance between the second vertical plate 212 and the third vertical plate 213, the air inlet 25 and the air outlet of the second static pressure channel 23 are both arranged on the second sealing plate 215, and the inter-row air conditioner 41 of the second cabinet group 4 opens at the corresponding position of the second sealing plate 215 to form the air inlet 25 of the second static pressure channel 23.

[0060] In one embodiment, an adjusting air valve 26 is provided at each air outlet for adjusting the size of the air outlet. By adjusting the size of the adjusting air valve 26, the air volume of the air outlet can be changed so that the air volume at each air outlet is balanced and uniform, which helps to reduce the temperature difference between each cabinet 42 in the cabinet group.

[0061] In one embodiment, the air duct structure 2 also includes a pressure stabilizing hood 27, which is arranged at the air inlet 25. Cold air is delivered from the air supply port at the top of the inter-row air conditioner 41. The airflow passes through the air inlet 25 and the pressure stabilizing hood 27 in sequence and then enters the static pressure channel. The airflow delivered by the inter-row air conditioner 41 stabilizes the wind speed and pressure when passing through the pressure stabilizing hood 27.

[0062] like Figure 6 As shown, the pressure stabilizing cover 27 includes a bottom frame 271, a pressure stabilizing member 272, a diffuser bevel 273 and a mesh plate 274. The bottom frame 271 is fixed at the air outlet of the inter-row air conditioner 41, the pressure stabilizing member 272 is arranged above the air outlet of the inter-row air conditioner 41, and the mesh plate 274 is arranged in parallel between the pressure stabilizing member 272 and the bottom frame 271. The diffuser bevel 273 is vertically arranged between the pressure stabilizing member 272 and the bottom frame 271, and the diffuser bevel 273 located on the same side has different inclination directions, so that the airflow is evenly delivered in multiple directions when passing through the diffuser bevel 273.

[0063] The mesh plate 274 includes a mesh plate with an opening rate of 80%, a mesh plate with an opening rate of 50% and a mesh plate with an opening rate of 20%, which are arranged in sequence along the direction from the bottom frame 271 to the pressure stabilizer 272. The inter-row air conditioner 41 is a centrifugal air supply. The wind speed and air volume are small near the air supply port of the inter-row air conditioner 41, and the wind volume and wind speed are large away from the air supply port. The upper and lower three layers of mesh plates 274 with different opening rates form a damping effect. After the air supply of the inter-row air conditioner 41 passes through each layer of mesh plates 274 with different opening rates, the wind pressure and wind speed of the upper and lower air outlets of the entire pressure stabilizing cover 27 are balanced. The balanced cold supply air passes through the diffuser bevels 273 at different angles on the pressure stabilizing cover 27 to stabilize the output of the air-conditioning cold supply air, and is evenly dispersed in three directions into the closed static pressure channel, so that the wind pressure and wind speed in the air duct structure 2 are more balanced.

[0064] In one embodiment, the micromodule room further includes a background main controller, each cabinet 42 is provided with a load monitor for monitoring the cabinet and a temperature collector for collecting temperature, and each regulating air valve 26 is provided with a differential pressure meter, which is used to measure the pressure difference between the air supply port of the inter-row air conditioner 41 and each of the air outlets of the static pressure channel. The load monitor, the temperature collector and the differential pressure meter are electrically connected to the background main controller.

[0065] The upper part of each cabinet 42 in the static pressure channel corresponds to a differential pressure meter and a damping plate 24. The function of the differential pressure meter is to measure the pressure difference between the inter-row air conditioner 41 and the upper part of each cabinet 42, and upload the pressure difference data to the background main controller. After calculation, the background main controller adjusts the height to be raised or lowered of each damping plate 24 to balance the air supply pressure of the entire static pressure channel.

[0066] There is an air regulating valve 26 at the air supply point of each cabinet 42 corresponding to the static pressure channel. There is a corresponding temperature collector inside each cabinet 42. After the temperature collector collects the temperature information, it is uploaded to the background main controller of the micromodule. The background main controller automatically adjusts the air volume required by the regulating valve 26 according to the collected temperature information, so as to achieve the purpose of accurately supplying air to each cabinet 42. The cold air accurately sent out by the regulating valve 26 reaches each cabinet 42, and the cabinet 42 absorbs the cold air from the cold air channel 5 at the front. After the heat exchange of the equipment inside the cabinet 42, the hot air is discharged to the hot air channel 6 at the rear of the cabinet 42. The air conditioner return air outlet is located in the hot air channel 6 at the rear of the equipment, and the hot air is absorbed to the air conditioner return air outlet to complete the heat exchange of the entire micromodule data center system.

[0067] Through the air supply pressure stabilization-flow dispersion-pressure equalization-regulation method, the inter-row air conditioner 41 provides precise air supply and cooling to each cabinet 42 on demand, real-time monitoring and adjustment, and the temperature difference is effectively controlled within 3°C, which effectively improves the efficiency of air conditioning refrigeration and air supply, solves the problem of large temperature difference in traditional air supply systems, avoids waste of air volume, has obvious energy-saving effects, and is simple to install and cooperate.

[0068] like Figure 7 As shown, an embodiment of the present invention provides a micromodule control method, which is applied to the micromodule computer room as described above, and the control method includes:

[0069] The load monitor acquires the cabinet data in real time, including load power, fan speed and wind speed, and uploads it to the background main controller;

[0070] The background main controller performs comprehensive calculations based on the data obtained by the load monitor, calculates the overall air volume demand based on the formula built into the background main controller, and sends a signal to the inter-row air conditioner 41, and the inter-row air conditioner 41 adjusts the cooling capacity and air supply volume based on the air volume demand;

[0071] After the inter-row air conditioner 41 delivers air according to the overall air volume demand, all the regulating air valves 26 are opened to the same initial position, and the differential pressure measuring meter in the static pressure channel detects the differential pressure at the position, and uploads the differential pressure data at different positions to the background main controller;

[0072] The background main controller calculates the height of each damping plate 24 according to the pressure difference data combined with the built-in formula, and adjusts the lifting height of the damping plate 24;

[0073] When the air supply of the inter-row air conditioner 41 reaches the set time, the pressure difference measuring meter re-detects the pressure difference and uploads it to the background main controller, and the background main controller determines whether the pressure difference at each position is balanced based on the re-detected pressure difference data;

[0074] After the pressure difference in the static pressure channel reaches equilibrium, the background main controller calculates the air volume demand of each cabinet 42 according to the data obtained in real time by the load monitor, and calculates the air volume required by each cabinet 42 through the built-in formula to readjust the size of the regulating air valve 26 corresponding to each cabinet 42, so as to change the size of the air volume flowing to the cabinet 42 through the regulating air valve 26;

[0075] When the air supply of the inter-row air conditioner 41 reaches the set time, the temperature collector collects the temperature data of the cabinet 42 and uploads the temperature data to the background main controller;

[0076] The background main controller determines whether the temperatures of the cabinets 42 are balanced based on the temperature data.

[0077] The air volume and temperature are managed and controlled through the micromodule control method to achieve the best air supply state, realize accurate air supply to each cabinet 42, make the cold and hot air flows more coordinated and smooth, and avoid the concentration of hot spots and the occurrence of air vortex phenomena.

[0078] The judgment process of whether the pressure difference at each position is balanced is as follows:

[0079] The background main controller calculates the average pressure difference of each position based on the pressure difference data, and compares the average pressure difference with the preset pressure difference (10Pa) to determine whether the pressure difference at each position in the static pressure channel has reached balance.

[0080] If the judgment result reaches the pressure difference balance, the background main controller does not send a correction signal, and each damping plate 24 maintains the original height position unchanged. If the judgment result is that the pressure difference is unbalanced, the correction data is reversely calculated based on the comparison between the average pressure difference and the preset pressure difference (10Pa), and a correction signal is sent to the background main controller. According to the correction signal, the height position of the damping plate 24 that exceeds the preset pressure difference is adjusted until the average pressure difference at each air outlet is within the preset pressure difference range.

[0081] The process of determining whether the temperatures of the cabinets 42 are balanced is as follows:

[0082] The background main controller calculates the average value through the temperature data in each cabinet 42, and compares the average value with the preset temperature difference (3°C) to determine whether the required air volume of each cabinet 42 is balanced.

[0083] If the judgment result reaches the temperature balance, the background main controller does not send a correction signal, and each regulating air valve 26 maintains the original opening size. If the judgment result is temperature imbalance, the correction data is reversely calculated based on the comparison between the temperature average value and the temperature difference (3°C), and a correction signal is sent to the background main controller.
