Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning energy conservation and emission reduction, and in particular to a side-inlet integrated cabinet and a temperature regulation method thereof. Background Art

[0002] With the large-scale deployment of 5G networks, the density of equipment inside cabinets in mobile communication base station electronic equipment, such as BBU centralized rooms, has increased significantly, and heat dissipation has become a key factor restricting system performance.

[0003] Traditional computer room air cooling solutions usually involve installing air conditioners in the room or arranging cold air ducts under the floor to achieve a uniform air supply pattern for the cabinets. This fails to achieve precise temperature control of specific areas inside the cabinets, resulting in poor heat dissipation. This greatly limits cooling efficiency, significantly increases air conditioning energy consumption, and causes energy waste. At the same time, cooling devices in existing technologies generally have problems such as uneven air distribution and low energy efficiency, resulting in unsatisfactory heat dissipation for equipment inside the cabinets, and may even cause risks such as equipment overheating, performance degradation, and damage.

[0004] Most mainstream BBU equipment has side-inlet and side-outlet air. Currently, there are some cabinet products with integrated heat dissipation functions for communication base station equipment with side-inlet and side-outlet on the market. For example, a built-in air-conditioning design is used to form a closed built-in circulating air path to solve the problem of dust-proof cabinet mesh doors. However, such equipment requires the built-in air-conditioning to be in a long-term working state, which has high energy consumption and high base station operating costs. In addition, for side-inlet and side-outlet base station equipment, current integrated cabinets all draw cold air from the cold zone at the front end of the rack, and use the air guide design arranged in the gap between the two BBU devices to guide the cold air from the cold zone at the front end of the rack to the side air inlet of the communication base station equipment, and then discharge the hot air from the side air outlet to the rear of the rack. This type of cabinet requires complex gap air guides, and the path for the cold air to reach the side air inlet is long, resulting in large cooling loss.

[0005] In addition, the front of the cabinet is usually densely packed with a large number of plug-in components and interface devices, which brings many inconveniences to the arrangement of cooling devices or cold air channels in front of the cabinet. Not only is the space limited and it is difficult to arrange the cooling system reasonably, but it may also cause interference to the cooling system during maintenance and replacement of components.

[0006] Therefore, how to achieve efficient and uniform cooling in a limited space while ensuring the convenience of operation at the front of the cabinet has become a technical problem that needs to be solved urgently. Summary of the Invention

The cold air passes through the air supply duct, the air supply duct outlet, and the electronic equipment air inlet and directly enters the electronic equipment.

[0014] Furthermore, it also includes a first wind shield, which is arranged on the same side of the shell and the air supply duct, that is, the first side of the electronic device, and the first wind shield is arranged close to the third side of the electronic device. The first wind shield and the inner wall of the shell and the electronic device form an independent cold air inlet cavity.

[0015] Furthermore, it also includes a second windshield, which is located on the fourth side of the electronic device and is arranged close to the second side of the electronic device. The second windshield, the inner wall of the shell, and the electronic device form an independent hot air outlet cavity.

[0016] Furthermore, a third wind shield is provided in the gap between the two upper and lower adjacent electronic devices, and the third wind shield includes a front panel, a middle partition and a rear panel. The third wind shield divides the gap into the gap air inlet and the gap air outlet. The gap air inlet is defined by the rear panel and the middle partition, and the gap air outlet is defined by the front panel and the middle partition. The gap air inlet and the gap air outlet are independent and isolated from each other.

[0017] Furthermore, the opening of the hot air outlet cavity and the gap air outlet are both facing the third side of the electronic device.

[0018] Furthermore, the side-inlet integrated cabinet is installed in a computer room with a computer room air conditioner.

[0025] The present invention also relates to a temperature regulation method for the side-inlet integrated cabinet, wherein the side-inlet integrated cabinet further comprises a controller and a temperature sensor, wherein the temperature sensor is used to detect the real-time temperature of hot air discharged from the electronic equipment air outlet of the electronic equipment, and specifically comprises the following steps:

[0026] Step 1: The controller controls the temperature sensor to sample the real-time temperature of the hot air discharged from the air outlet of the electronic device every 2 seconds and report the sample to the controller;

[0027] Step 2: The controller controls the working mode of the side-inlet integrated cabinet according to the relationship between the sampled hot air real-time temperature and the set temperature value (45°C). The specific working modes are as follows:

[0028] When the real-time hot air temperature is lower than the set temperature value, the side-inlet integrated cabinet enters a first operating mode, wherein the air conditioner does not work, the electronic equipment absorbs indoor air from the computer room through the gap between the air supply duct and the electronic equipment and / or the gap air inlet, and step 1 is continued;

[0029] When the real-time temperature of the hot air is higher than the set temperature value, the side-inlet integrated cabinet enters the second working mode, which is: 1) controlling the air conditioner to start and run a cooling working cycle (6 minutes); 2) after one cooling working cycle, the controller controls the temperature sensor to detect the real-time temperature of the hot air and report it. If the real-time temperature of the hot air is lower than the set temperature value, the air conditioner is controlled to stop working directly and perform a stop cooling cycle (3 minutes); if the real-time temperature of the hot air is still higher than the set temperature value, the air conditioner is continued to be controlled to perform a cooling working cycle until the real-time temperature of the hot air is lower than the set temperature value, at which point the controller controls the air conditioner to stop working and perform a stop cooling cycle;

[0030] Step 3: Continue with step 1 and repeat the above steps.

[0031] The present invention has the following beneficial effects:

[0032] The present invention arranges an air supply duct on a first side of an electronic device having an air inlet, and provides an air supply duct outlet at a position on the air supply duct corresponding to the air inlet of the electronic device, so as to directly supply cold air to the electronic device, so that the cold air can enter the electronic device more directly, reducing unnecessary heat transfer and loss, thereby achieving a more efficient cooling effect.

[0034] The cabinet structure of the present invention ensures that the cool air in the cold zone comes primarily from two sources: the first source is the indoor cold air from the front of the cabinet, which is affected by the computer room air conditioning; the second source is the cold air from the air conditioner, which is further cooled by the air conditioner. By detecting the real-time temperature of the hot air discharged from the electronic equipment outlet and comparing it with the set temperature value, the cabinet is controlled to switch between different operating modes, achieving intelligent temperature control, ensuring effective cooling of the electronic equipment while also saving energy.

DETAILED DESCRIPTION

[0056] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0057] Example 1

[0058] Overall structure of side-inlet integrated cabinet

[0059] A side-inlet integrated cabinet, see Figures 1-4 The present invention comprises a housing 1, an air cooler 3, and an air supply duct 4. The air cooler 3 and air supply duct 4 are disposed within the housing 1. The housing 1 is used to house an electronic device 2. In this embodiment, the electronic device 2 is a BBU device, but may also be other electronic devices suitable for cooling within a cabinet. Multiple electronic devices 2 are installed within the housing 1, spaced apart from each other along the height direction from top to bottom. The air cooler 3 is mounted at the bottom of the housing 1, below the electronic device 2. The air supply duct 4 is located on a first side of the electronic device 2. The air cooler 3 and the air supply duct 4 are connected by a connecting duct 5. The air supply duct 4 is provided with a plurality of air supply duct outlets 41 at positions corresponding to positions of the housing 1 suitable for mounting the electronic device 2. The electronic device 2 is provided with an electronic device air inlet 21 on the first side and an electronic device air outlet 23 on a fourth side opposite the first side. Each air supply duct outlet 41 corresponds to the electronic device air inlet 21 on the first side of the electronic device 2, forming an air flow between the two, so that the cool air blown out of the air supply duct outlet 41 can be directly supplied to the electronic device 2. A gap is defined between two adjacent electronic devices 2, each of which has a gap air inlet 22 and a gap air outlet 24. The gap air inlet 22 is located on a second side of the electronic device 2, adjacent to the first side, and the gap air outlet 24 is located on a third side opposite the second side. In this embodiment, the first side is the left side of the cabinet, the second side is the front side of the cabinet (i.e., the operating side), the third side is the rear side of the cabinet, and the fourth side is the right side of the cabinet.

[0060] In this embodiment, the design of integrating the air cooler 3 and the air supply duct 4 into the cabinet can avoid excessive and complicated piping arrangements, reduce the space occupied by the computer room, make more efficient use of the computer room space, improve the overall utilization rate of the computer room, and bring great convenience to the operation, maintenance and management of the computer room. In addition, this embodiment arranges the air supply duct on the first side of the electronic equipment with the air inlet, and sets the air supply duct outlet at a position on the air supply duct corresponding to the air inlet of the electronic equipment, so that cold air is directly supplied to the electronic equipment 2, allowing the cold air to enter the electronic equipment 2 more directly, reducing unnecessary heat transfer and loss, and further improving cooling efficiency.

[0061] like Figure 3-Figure 4 The side air inlet integrated cabinet further includes a first windshield 6, combined with Figure 16-17 As can be seen, the first air shield 6 and the air supply duct 4 are arranged on the same side of the housing 1, namely, the first side of the electronic device 2, and the first air shield 6 is arranged near the third side, opposite the second side of the electronic device 2, which is the rear side of the cabinet. The first air shield 6 separates the left side of the cabinet from the rear side, forming two isolated spaces. Specifically, an independent cold air inlet cavity is formed between the first air shield 6 and the inner wall of the housing 1 and the electronic device 2.

[0062] In this embodiment, the provision of the first air shield 6 ensures that the cold air entering the cabinet can be directed into the electronic device 2 through the cold air inlet cavity, and prevents the cold air in the cold air inlet cavity from escaping from the rear of the cabinet, thereby avoiding waste of cooling energy. In this embodiment, the first air shield 6 also serves to block hot air, preventing hot air from entering the cold air inlet cavity from the rear of the cabinet, thus preventing the mixing of cold and hot air, ensuring the stability of the temperature zones within the cabinet, and allowing cold air to continuously enter the electronic device 2, thereby improving cooling efficiency and optimizing overall heat dissipation performance.

[0063] like Figure 3-Figure 4 The side air inlet integrated cabinet further includes a second windshield 7, combined with Figure 16-17 As can be seen, the second air shield 7 is located on the fourth side of the electronic device 2, opposite the first side, which is the right side of the cabinet. The second air shield 7 is arranged close to the second side of the electronic device 2. The second air shield 7 separates the right side of the cabinet from the front space, forming two isolated spaces. Specifically, an independent hot air outlet cavity 9 is formed between the second air shield 7, the inner wall of the housing 1, and the electronic device 2.

[0064] In this embodiment, the provision of the second air baffle 7 can ensure that the direction of hot air flow inside the cabinet is effectively controlled. When hot air is generated and attempts to be discharged from the front side of the cabinet, the second air baffle 7 can effectively block its flow, thereby guiding the hot air to flow out from the hot air outlet cavity 9 of the cabinet, ensuring that the hot air and cold air flow inside the cabinet are independent of each other and do not interfere with each other, thereby avoiding the problem of low efficiency in the cooling zone caused by the mixing of cold air and hot air. In addition, the provision of the second air baffle 7 forms an independent hot air flow path inside the cabinet, realizing reasonable control of the air flow inside the cabinet. For example, after the cold air enters the electronic device 2 and undergoes heat exchange, the hot air is discharged into the hot air outlet cavity 9 from the electronic device outlet 23 on the fourth side of the electronic device 2 and then discharged outside the cabinet, or the hot air is discharged from the electronic device outlet 23 on the fourth side of the electronic device 2 and flows out of the cabinet through the gap outlet 24 between two adjacent electronic devices 2.

[0065] like Figure 3-Figure 4 A third windshield 8 is provided between the two adjacent electronic devices 2. Figure 16-17 It can be seen that the third wind shield includes a front panel 81, a middle partition 82 and a rear panel 83. The third wind shield 8 divides the gap between two adjacent electronic devices 2 into two independent gap air inlets 22 and gap air outlets 24. The gap air inlet 22 is defined by the rear panel 83 and the middle partition 82, and the gap air outlet 24 is defined by the front panel 81 and the middle partition 82.

[0066] The third windshield 8 divides the gap between the electronic devices 2 into two independent gap air inlets 22 and gap air outlets 24. The gap air inlet 22 is a cold air circulation area, and the gap air outlet 24 is a hot air circulation area. The gap air inlet 22 is mainly responsible for receiving the cold air in the computer room entering from the front of the cabinet, while the gap air outlet 24 is responsible for discharging the hot air after heat exchange with the electronic devices 2 to the back of the cabinet. The cold air in the computer room entering the cabinet from the front of the cabinet and the hot air discharged from the back of the cabinet are completely isolated and separated, avoiding cross-interference between the two. This not only ensures that the cold air in the computer room can be continuously and stably supplied to the electronic devices 2, but also prevents the hot air from flowing into the cold air circulation area through the gaps between adjacent electronic devices 2, thereby interfering with and neutralizing the cold air, thereby significantly improving the cooling effect.

[0067] like Figures 1-4 As shown, the air conditioner 3 includes an air conditioner air inlet 31. In this embodiment, the air conditioner air inlet 31 and the gap air inlet 22 are both oriented toward the second side of the electronic device 2, that is, toward the front side of the cabinet. The opening direction of the hot air outlet cavity 9 and the gap air outlet 24 are both oriented toward the third side of the electronic device 2, that is, the rear side of the cabinet. In this embodiment, the opening directions of the air conditioner air inlet 31 and the hot air outlet cavity 9 are arranged in two opposite directions, which can separate and manage the cold air in the machine room entering the cabinet and the hot air discharged from the cabinet, effectively preventing the discharged hot air from flowing back to the air conditioner air inlet 31 or being mixed with the cold air in the machine room and then entering the air conditioner air inlet 31, thereby preventing the hot air discharged from the cabinet from weakening the cooling effect of the cold air.

[0068] This embodiment employs an integrated cabinet design with open front and rear sides, or with front and rear doors located on the front or rear of the cabinet, each of which is a mesh door or lattice door with through holes. Because connectors and other devices are located on the front of the cabinet, the space at the front of the cabinet is often larger than that at the rear to facilitate equipment maintenance. Airflow at the front of the cabinet is generally significantly better than at the rear, and the air conditioning in the computer room has a greater impact on the front of the cabinet. Therefore, this arrangement with opposite air inlet and outlet directions helps fully utilize the cooling capacity of the computer room air conditioning, further improving cooling efficiency.

[0069] In summary, in this embodiment, through the position and structural setting of the air conditioner 3, the air supply duct 4, the first air shield 6, the second air shield 7 and the third air shield 8 in the cabinet, the side air inlet integrated cabinet successfully realizes the diversion management of cold air and hot air, and the second side, the first side and the gap air inlet of the electronic equipment 2 are enclosed into a cold zone, and the fourth side, the third side and the gap air outlet of the electronic equipment 2 are enclosed into a hot zone. The cold zone and the hot zone form two independent gas flow passages. On the one hand, it ensures that the cold air in the cold zone can be directly and efficiently supplied to the inside of the electronic equipment 2 to achieve the best cooling effect; on the other hand, it also avoids the hot air in the hot zone from flowing back into the cold zone, thereby ensuring the improvement of cooling efficiency in the process of cooling the cabinet.

[0070] Specifically, in this embodiment, the cold air in the cold zone mainly comes from two sources: the first source is the indoor cold air affected by the air conditioner in the computer room at the front of the cabinet, and the second source is the cold air that is further cooled by the air conditioner. Specifically, the electronic equipment air inlet 21 has at least a first cold air inlet path and a second cold air inlet path, see Figure 18 The first cold air inlet path is as follows: after being cooled by the computer room air conditioner, the cold air in the room can enter the gap between the two electronic devices 2 from the front of the cabinet or through the through-holes in the front cabinet door, and then enter the electronic device air inlet 21. The second cold air inlet path is as follows: the air conditioner 3 absorbs the cold air in the room at the front of the cabinet through the air conditioner air inlet 31, and after further heat exchange and cooling, it outputs cold air. The cold air passes through the air supply duct 4, the air supply duct outlet 41, and the electronic device air inlet 21, and can be directly blown into the electronic device 2. This design ensures that cold air is fully and multi-channeled supplied to the interior of the electronic device 2, achieving a highly efficient cooling effect.

[0071] In addition, specifically, in this embodiment, the electronic equipment air outlet 23 mainly includes a first hot air exhaust path and a second hot air exhaust path, see Figure 19The first hot air exhaust path is: the hot air blown out of the electronic equipment air outlet 23 is directly discharged from the cabinet through the hot air outlet cavity 9 defined by the second wind shield 7 and the inner wall of the shell 1; the second hot air exhaust path is: the hot air blown out of the electronic equipment air outlet 23 enters the gap between two adjacent electronic devices 2, and flows out through the gap air outlet 24 on the rear side of the cabinet.

[0072] Air supply duct structure

[0073] In this embodiment, the air supply duct 4 has a plurality of branch air ducts 42 , each of the branch air ducts 42 is independently provided, and the number of the branch air ducts 42 is the same as the number of the electronic equipment air inlets 21 of each electronic equipment 2 .

[0074] Specifically, such as Figure 5-Figure 7 As shown, in this embodiment, an air supply duct inlet 47 is provided below the air supply duct 4, and the connecting duct 5 is connected to the air supply duct inlet 47. A number of built-in partitions 46 are provided in the air supply duct 4. These built-in partitions 46 divide the air supply duct 4 into a plurality of independent branch ducts 42. Each branch duct 42 has an independent air supply path and a corresponding air supply duct outlet 41. Figure 6-Figure 7 The air supply duct 4 is internally spaced apart with four internal baffles 46. At the air supply duct inlet 47, adjacent internal baffles 46 merge into one, ultimately forming three independent branch ducts 42. Each branch duct 42 is slightly wider than the width of the air supply duct outlet 41. The three branch ducts 42 are independent and do not interfere with each other, which can further concentrate the wind force within each branch duct, thereby further improving cooling efficiency.

[0075] According to Bernoulli's principle, the flow rate is inversely proportional to the cross-sectional area of ​​the pipe. Therefore, by reasonably designing the cross-sectional area of ​​the branch duct 42, the wind speed is faster in the branch duct 42 with a smaller cross-sectional area, thereby being able to more effectively remove heat and improve cooling efficiency.

[0076] A corresponding number of air duct outlets 41 are arranged side by side at the same height of the multiple branch air ducts 42, so that the air duct 4 includes three rows of air duct outlets, and each row of air duct outlets has multiple air duct outlets 41. Typically, the first side of each electronic device 2 includes multiple electronic device air inlets 21 arranged in parallel. This design ensures that each electronic device air inlet 21 on the side of the electronic device 2 corresponds to an air duct outlet 41, which can greatly increase the cooling range, avoid cooling dead corners in the electronic device, uneven air volume distribution, and ineffective cooling in some areas, and ensure the overall heat dissipation effect is optimized.

[0077] In addition, if Figure 8As shown, the air supply duct 4 has an inclined pressure regulating plate 43, and the pressure regulating plate 43 and the inner wall of the air supply duct 4 form a gas circulation duct 44. The cross-sectional area of ​​the gas circulation duct 44 gradually decreases along the gas flow direction, that is, in the height direction of the cabinet, the distance between the second side of the electronic equipment 2 and the pressure regulating plate 43 gradually decreases from bottom to top.

[0078] When the cross-section of the duct cavity is consistent, the dynamic pressure of the internal airflow gradually decreases along the direction of gas flow, while the static pressure gradually increases. This is because the gas is affected by friction and resistance during flow, which causes kinetic energy to be converted into internal energy, thereby reducing the dynamic pressure. At the same time, the interaction and collision between gas molecules are enhanced, which increases the static pressure and causes inconsistent wind pressure and wind speed at each outlet. By providing an inclined pressure regulating plate 43 and gradually reducing the space of the gas circulation duct 44 near the top of the air supply duct 4, the wind speed and wind pressure at each point of the gas circulation duct 44 can be balanced, ensuring that the outlet wind pressure and wind speed at each air supply duct outlet 41 are basically consistent.

[0079] In this embodiment, the air supply duct 4 can be arranged in sections, see Figures 5-10 The air supply duct includes several sub-air supply ducts 45, and two adjacent sub-air supply ducts 45 are detachably connected; each sub-air supply duct 45 has a sub-pressure regulating plate 431, and the pressure regulating plate 43 is formed by several sub-pressure regulating plates 431 connected to each other.

[0080] The sub-air supply ducts 45 can be connected to each other by plugging to form the air supply duct 4. This arrangement enables the air supply duct 4 to be flexibly assembled and disassembled, simplifies the installation process, and makes subsequent maintenance work extremely convenient. When a section of the sub-air supply duct 45 fails, it is only necessary to inspect or replace the section of the sub-air supply duct 45 without large-scale disassembly of the entire air supply duct 4, saving maintenance time and cost.

[0081] In this embodiment, the connecting pipe 5 is arc-shaped, and a plurality of arc-shaped air distribution plates 51 are provided in the connecting pipe 5. Figure 11 By providing a plurality of arc-shaped air distribution plates 51 inside the connecting duct 5, the cold air flow entering the connecting duct 5 can be effectively evenly distributed and guided, thereby preventing the air flow from forming vortices or dead corners therein, thereby reducing energy loss and improving overall ventilation efficiency. At the same time, the provision of the arc-shaped air distribution plates 51 also has a certain noise reduction effect, which can reduce the noise generated when the air flow passes through the connecting duct 5 to a certain extent, thereby improving the user experience.

[0082] In the present invention, the form and specific structure of the air supply duct are not limited to the scope described in this embodiment, and may also be:

[0083] (1) Single pipeline

[0084] The air supply duct 4 is an integrated single duct structure. Figure 12-13 The air supply duct 4 only includes a single air duct, and the air outlet 41 of the air supply duct adopts an oblong design.

[0085] (2) Dual pipeline

[0086] The air supply duct 4 is an integrated double-duct structure. Figure 14-15 An air supply duct inlet 47 is provided below the air supply duct 4. The air supply duct 4 is divided into two and extends upward from the air supply duct inlet 47 to form two separate branch ducts 48. Each branch duct 48 is provided with multiple air supply duct outlets 41.

[0087] The air supply duct 4 adopts an integrated double-duct structure, which is divided into two branch ducts 48 from the air supply duct inlet 47. This one-in-two design ensures that the cold air can be evenly distributed to two different paths. The cold air can be blown directly to the electronic equipment 2 that needs to be cooled, achieving a fixed-point and efficient cooling effect. Multiple air supply duct outlets 41 are set on each branch duct 42, so the cooling area is effectively expanded to achieve a uniform cooling effect.

[0088] Example 2

[0089] In this embodiment, the cooling power of the air conditioner 3 is 5 kW, and the maximum output air volume of the air supply duct outlet is 900 m³ / h. In this embodiment, the electronic device 2 is a BBU device. The cabinet is 80 cm wide, 60 cm thick, and 220 cm high. The BBU thickness is 2U, and 1U = 4.445 cm. In this embodiment, 12 BBUs can be placed in the cabinet, and the spacing between the upper and lower BBU devices is 1U.

[0090] This embodiment relates to a temperature regulation method for the above-mentioned side-inlet integrated cabinet. The side-inlet integrated cabinet further includes a controller and a temperature sensor. The temperature sensor is disposed in the hot air outlet cavity 9 and is used to detect the real-time temperature of the hot air discharged from the electronic device outlet 23 of the electronic device 2. The method specifically includes the following steps:

[0091] Step 1: The controller controls the temperature sensor to sample the temperature in the hot air outlet cavity 9 every 2 seconds, obtains the real-time temperature of the hot air, and reports it to the controller;

[0092] Step 2: The controller controls the working mode of the side-inlet integrated cabinet according to the relationship between the sampled hot air real-time temperature and the set temperature value (the default is 45°C). The specific working modes are as follows:

[0093] When the real-time temperature of the hot air is lower than the set temperature value, the side-inlet integrated cabinet enters the first operating mode, wherein the air conditioner 3 does not work, the electronic device 2 absorbs the cold air in the computer room through the gap between the air supply duct 4 and the electronic device 2 and / or the gap air inlet 22, and step 1 is continued;

[0094] When the real-time temperature of the hot air is higher than the set temperature value, the side-inlet integrated cabinet enters the second working mode, which is: 1) controlling the air conditioner 3 to start and run a cooling working cycle (the default is 6 minutes); 2) after one cooling working cycle, the controller controls the temperature sensor to detect the real-time temperature of the hot air. If the real-time temperature of the hot air is lower than the set temperature value, the air conditioner 3 is controlled to stop working directly and perform a stop cooling cycle (the default is 3 minutes); if the real-time temperature of the hot air is still higher than the set temperature value, the air conditioner 3 is continued to be controlled to perform a cooling working cycle until the real-time temperature of the hot air is lower than the set temperature value, at which point the controller controls the air conditioner 3 to stop working and perform a stop cooling cycle (the default is 3 minutes);

[0095] Step 3: Continue with step 1 and repeat the above steps.

[0096] A computer room air conditioner is installed inside the computer room. In this embodiment, the supply of cold air required for cabinet cooling relies primarily on two sources: one is cold air from the front of the cabinet affected by the computer room air conditioner, and the other is cold air from the air conditioner that further cools the cold air from the first source. This embodiment fully considers these two sources of cold air and achieves efficient switching between two operating modes. In the first operating mode, when the temperature of the hot air exhausted by the electronic device 2 is lower than the preset set temperature value, i.e., the preset threshold, for energy conservation reasons, there is no need to turn on the air conditioner 3. The electronic device 2 absorbs the indoor cold air from the front of the cabinet affected by the computer room air conditioner and enters the electronic device through the gap between the electronic device 2 and the air supply duct 4 and the gap between the upper and lower electronic devices 2 through the air inlet 22, thereby effectively cooling the electronic device 2. However, when the temperature of the hot air discharged from the electronic device 2 rises and exceeds the set temperature value, the second working mode must be activated to ensure the normal operation of the electronic device 2. At this time, the air conditioner 3 is controlled to turn on, and the air cooled by the computer room air conditioner enters from the air inlet of the air conditioner 3. After further heat exchange and cooling, the cold air is directly and continuously supplied to the electronic device 2 through the air supply duct 4. Through the intelligent switching of the above two working modes, not only can the cooling method be flexibly adjusted according to actual needs to ensure that the temperature inside the electronic device 2 is always maintained at a low level without the need for the air conditioner to work all day to continuously deliver cold air, but it can also achieve efficient utilization and effective conservation of energy while ensuring the heat dissipation effect, providing a strong guarantee for the safe and stable operation of the computer room.
