Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an inter-row air conditioner. Background Technology

[0002] In-row air conditioning is a commonly used cooling device in data centers, enabling precise cooling of server racks. With the continuous development of big data technology, user demands for data centers are constantly increasing, leading to a growing demand for commercial in-row air conditioning systems for data center cooling. To meet the cooling capacity and air conditioning volume requirements of customers in different environments, the functions and types of fans used in in-row air conditioning systems are becoming increasingly diverse.

[0003] However, during operation, existing in-row air conditioners may experience problems due to improper airflow organization, fan malfunctions, environmental requirements, or other factors. When a fan stops, the airflow resistance inside the fan decreases, while the airflow resistance outside the fan is greater than the inside. Under pressure, this creates reverse airflow, causing the stopped fan to rotate in the opposite direction to the normal fan. This results in an airflow short-circuit, where cold air bypasses the server rack's cooling area and instead flows back to the air conditioner's outlet via the air conditioner itself or other pathways. This reduces cooling efficiency, leads to uneven temperature distribution in the server room, and may even cause equipment overheating. Utility Model Content

[0004] This utility model provides an inter-row air conditioner, which aims to solve the problem of airflow short circuit caused by the fan reversing due to the influence of the surrounding airflow after the existing inter-row air conditioner fan stops due to failure.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0035] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0036] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0037] As used in this specification and the appended claims, the term "if" may be interpreted, depending on the context, as "when," "once," "in response to determination," or "in response to detection." Similarly, the phrases "if determined" or "if [described condition or event] is detected" may be interpreted, depending on the context, as "once determined," "in response to determination," "once [described condition or event] is detected," or "in response to detection of [described condition or event]."

[0038] To facilitate understanding of this utility model, the inter-row air conditioner provided in the embodiments of this utility model will be described first. (Refer to...) Figures 1 to 11 For details, please refer to Figures 1 to 5 This utility model provides an inter-row air conditioner, which includes: a cabinet 1, wherein the cabinet 1 is provided with an evaporator 11 for preparing cold air; a fan module 2, including multiple axial fan modules 21, all of which are arranged vertically on one side of the cabinet 1 in the horizontal direction and adjacent to the evaporator 11, and each axial fan module 21 is provided with an air outlet 201, which is used to transport the cold air prepared by the evaporator 11 to the outside of the cabinet 1 through the air outlet 201; and a sealing mechanism 3, which is provided on each axial fan module 21, and is used to seal the air outlet 201 on the axial fan module 21 when the axial fan module 21 stops abnormally.

[0039] In traditional in-row air conditioning systems, if the airflow organization of the axial flow fan units is unreasonable, or if one fan fails and stops, the airflow resistance inside the faulty fan decreases, while the airflow resistance outside the faulty fan becomes greater than that inside. This creates a pressure difference between the inside and outside of the faulty fan. Under the influence of this pressure, airflow in the opposite direction is generated, causing the faulty fan to rotate in reverse, opposite to its normal rotation direction. This results in airflow short-circuiting, with cold air flowing back directly through the air conditioner itself or through other paths. This reduces the cooling efficiency of the air conditioner, leading to uneven temperature distribution in the computer room and causing problems such as equipment overheating.

[0040] To address the aforementioned problems, this embodiment provides an inter-row air conditioner, primarily used in data center server rooms to dissipate heat from servers and other equipment within the room. Figures 1 to 5 As shown, the inter-row air conditioner includes a cabinet 1, a fan module 2, and a sealing mechanism 3. The cabinet 1 is the housing 211 of the air conditioner, used to install various air conditioning components and provide protection. An evaporator 11 is installed inside the cabinet 1. The evaporator 11 is the main component of the air conditioner for heat exchange with the external environment, and it is mainly composed of copper pipes. The evaporator 11 works in conjunction with the outdoor unit of the inter-row air conditioner to produce cold air. Air inlets are provided at the rear or side of the cabinet 1 for air circulation. The fan module 2 is mounted on one side of the cabinet 1, adjacent to the evaporator 11 inside the cabinet 1, and is used to deliver cold air to the outside of the cabinet 1. The fan module 2 consists of multiple axial fan modules 21. The specific number of axial fan modules 21 is unlimited. All axial fan modules 21 are arranged vertically on one side of the cabinet 1 in the horizontal direction, and each axial fan is adjacent to the evaporator 11. Each axial fan module 21 can independently deliver cold air. Specifically, the axial fan module 21 is equipped with an air outlet 201. The fan blades of the axial fan module 21 are assembled in the air outlet 201. The air inlet side of the air outlet 201 faces the evaporator 11 inside the cabinet 1, and the air outlet side of the air outlet 201 faces outward. When the axial fan module 21 is running, the fan blades rotate, and the cold air prepared by the evaporator 11 is delivered to the outside of the cabinet 1 through the air outlet 201, thereby regulating the ambient temperature of the computer room and cooling the equipment in the computer room. A sealing mechanism 3 is provided on each axial fan module 21, that is, each axial fan module 21 is equipped with a separate sealing mechanism 3. The sealing mechanism 3 is used to seal the air outlet 201 on the axial fan module 21 when the axial fan module 21 stops abnormally. Specifically, both the blocking mechanism 3 and the axial flow fan module 21 are connected to the control system of the inter-row air conditioner and are controlled by the control system. Under the control of the control system, the blocking mechanism 3 can block the air inlet side or air outlet side of the air outlet 201 of the axial flow fan module 21. After the air outlet 201 is blocked, airflow channels cannot be formed on both sides of the axial flow fan module 21.

[0041] In practical applications, the control system of the inter-row air conditioner has monitoring logic in its program. The control system can detect the operating status of each axial fan module 21 in real time and determine whether the axial fan module 21 has malfunctioned and stopped. Abnormal shutdown faults of the axial fan module 21 may include short circuit faults, open circuit faults, etc. When the control system determines that the axial fan module 21 has abnormally stopped, it outputs a control signal to the sealing mechanism 3, causing the sealing mechanism 3 to block the air outlet 201 on the abnormally stopped axial fan module 21, thereby preventing airflow from forming on both sides of the abnormally stopped fan. In this way, even if other normal axial flow fan modules 21 are operating normally, causing the airflow resistance on the inlet side of the abnormal axial flow fan module 21 to be less than the airflow resistance on the outlet side, the airflow cannot circulate through the air outlet 201 because no airflow channel is formed. Therefore, the malfunctioning axial flow fan module 21 will not be affected by the airflow and will not reverse, thus avoiding the phenomenon of airflow short circuit. This ensures that the abnormal shutdown of the axial flow fan module 21 will not have a significant impact on the overall temperature distribution of the computer room, and the temperature control effect of the in-row air conditioner on the computer room is more stable and reliable.

[0042] In one embodiment, reference is made to Figure 4 and Figure 5 The axial flow fan module 21 includes a housing 211 and axial flow fan blades 212. An air outlet 201 is located on the housing 211 and extends through both sides of it. The axial flow fan blades 212 are rotatably mounted inside the air outlet 201. A sealing mechanism 3 is located on the side of the housing 211 facing the evaporator 11. The sealing mechanism 3 seals the air inlet side of the air outlet 201 when the axial flow fan module 21 stops abnormally. In specific implementations, the axial flow fan module 21 mainly includes a housing 211 and axial flow fan blades 212, and also includes components such as a motor. The housing 211 of the axial flow fan module 21 has a square structure, and the air outlet 201 is located on the housing 211 and extends through both the front and rear sides of the housing 211. Figure 7As shown, a handle groove 2110 is provided on the side of the housing 211 away from the evaporator 11 to facilitate the pushing and pulling of the axial fan module 21. The axial fan blade 212 can be composed of an impeller with multiple blades connected in the center. The rotation radius of the axial fan blade 212 is smaller than the diameter of the air outlet 201. The axial fan blade 212 is rotatably mounted in the air outlet 201 and is driven by a motor. A wire hole 203 is provided on the side of the housing 211 of the axial fan module 21 facing the evaporator 11 to facilitate the passage of the motor wires. The sealing mechanism 3 is mainly set on the side of the housing 211 of the axial fan module 21 facing the evaporator 11. It can seal the air inlet side of the air outlet 201, which is the side of the air outlet 201 facing the evaporator 11 inside the cabinet 1. In practical applications, when the control system detects that the axial fan module 21 has stopped abnormally, the control blocking mechanism 3 blocks the air inlet side of the air inlet 201 of the abnormally stopped axial fan module 21. By blocking the air inlet side of the air inlet 201, the axial fan blade 212 can be isolated from the rear end of the axial fan module 21, which can reduce the impact of the axial fan blade 212 reversing. Even if the axial fan blade 212 is reversed due to other external factors, the rear end of the abnormally stopped axial fan module 21 will not experience short-circuit airflow to the evaporator 11 inside the cabinet 1, which can better avoid airflow short-circuiting.

[0043] In a further embodiment, refer to Figures 4 to 6 The sealing mechanism 3 includes an expansion drive assembly 31 and a flexible baffle 32. The expansion drive assembly 31 is located on the side of the housing 211 facing the evaporator 11. A portion of the flexible baffle 32 is connected to the housing 211, and another portion is connected to the expansion drive assembly 31. The expansion drive assembly 31 drives the flexible baffle 32 to expand radially in the air outlet 201 to block the air inlet side of the air outlet 201. Specifically, the sealing mechanism 3 mainly includes an expansion drive assembly 31 and a flexible baffle 32. The expansion drive assembly 31 is located on the side of the axial fan module 21 whose housing 211 faces the evaporator 11. A portion of the flexible baffle 32 is connected to the housing 211 of the axial fan module 21, and another portion is connected to the expansion drive assembly 31. Specifically, the flexible baffle 32 is designed with flexible material, allowing it to be folded and rolled up. The flexible baffle 32 has low air permeability and good toughness. The overall area of ​​the flexible baffle 32 can completely cover the entire air outlet 201. Under normal conditions, the flexible baffle 32 is in a retracted state. When the axial flow fan module 21 stops abnormally, the stretching drive component 31 can drive the flexible baffle 32 to stretch out radially in the air outlet 201, so that the flexible baffle 32 completely covers the air inlet side of the entire air outlet 201, thereby blocking the air inlet side of the air outlet 201 and preventing airflow short circuit.

[0044] In a further embodiment, refer to Figures 4 to 6The stretching drive assembly 31 includes a first guide rail 311, a first drive member 312, and a connecting rod 313. The first guide rail 311 is horizontally disposed on the top of the housing 211. The first drive member 312 is connected to the first guide rail 311. One end of the connecting rod 313 is connected to the first drive member 312 and is higher than the upper edge of the air vent 201. The other end extends vertically and exceeds the lower edge of the air vent 201. A portion of the flexible baffle 32 is fixed to the housing 211 near the edge of the air vent 201, and the other portion is rolled up on the connecting rod 313. The first drive member 312 is used to slide along the first guide rail 311 and drive the connecting rod 313 to rotate so that the flexible baffle 32 is horizontally unfolded to block the air inlet side of the air vent 201. In specific implementation, the stretching drive assembly 31 mainly includes a first guide rail 311, a first drive component 312, and a connecting rod 313. The first guide rail 311 is a track structure, which is horizontally set at the top position on one side of the evaporator 11 of the housing 211. The length of the first guide rail 311 is greater than the width between the left and right sides of the air outlet 201. The first drive component 312 is slidably connected to the first guide rail 311. The first drive component 312 can be a motor. The connecting rod 313 is a straight rod-shaped structure. The connecting rod 313 is vertically set. One end of the connecting rod 313 is connected to the first drive component 312 and is higher than the upper edge of the air outlet 201. The other end of the connecting rod 313 extends vertically and exceeds the lower edge of the air outlet 201. Overall, the connecting rod 313 spans the upper and lower sides of the air outlet 201 in the vertical direction. A portion of the flexible baffle 32 is fixed to the edge of the housing 211 near the air vent 201, below the first guide rail 311. The other portion of the flexible baffle 32 is rolled up onto the connecting rod 313, at which point the entire flexible baffle 32 is in a retracted state. In practical applications, the first driving component 312 can move along the first guide rail 311, and while moving along the first guide rail 311, it can drive the connecting rod 313 to rotate. The rotation of the connecting rod 313 releases the portion of the flexible baffle 32 rolled up onto the connecting rod 313, and the movement of the first driving component 312 causes the connecting rod 313 to move together, thereby causing the flexible baffle 32 to unfold horizontally to block the air inlet side of the air vent 201. Specifically, the first driving component moves the connecting rod 313 along the first guide rail 311 from one end to the other, and while moving, the connecting rod 313 rotates, causing the rolled-up portion of the flexible baffle 32 to gradually release and cover the air inlet side of the air vent 201 until the air inlet side of the air vent 201 is completely covered, thus completing the blockage. When the axial flow fan module 21 returns to normal, the first drive component moves along the first guide rail 311 in the opposite direction with the connecting rod 313. At the same time, the connecting rod 313 rotates in the opposite direction, so that the flexible baffle 32 is gradually rolled up onto the connecting rod 313 until the air inlet side of the air outlet 201 is fully visible, thus completing the reset.

[0045] In one embodiment, reference is made to Figure 4 and Figure 7 A protective net 2101 is installed on the air inlet side and / or air outlet side of the air outlet 201. Specifically, the protective net 2101 can be installed on the air inlet side of the air outlet 201 on the housing 211 of the axial flow fan, or on the air outlet side of the air outlet 201 on the housing 211 of the axial flow fan, or simultaneously on both the air inlet and outlet sides of the air outlet 201 on the housing 211 of the axial flow fan. The protective net 2101 is flush with the surface of the housing 211 and will not affect the sealing operation of the sealing mechanism 3 on the air outlet 201. In practical applications, the protective net 2101 does not affect the airflow through the air outlet 201 and provides a protective function, preventing insects and other debris from entering the axial flow fan module 21 and affecting the operation of the axial flow fan blades 212.

[0046] In one embodiment, reference is made to Figure 1 and Figure 2 The cabinet 1 has multiple vertically parallel support frames 12 protruding from one side in the horizontal direction. Each axial fan module 21 is slidably mounted on each support frame, and the axial fan module 21 can slide horizontally outward relative to the support frame 12. In specific implementation, multiple vertically parallel support frames 12 protrude from one side of the cabinet 1 in the horizontal direction. The number of support frames 12 corresponds to the number of axial fan modules 21. The support frames 12 are used to install the axial fan modules 21. Each axial fan module 21 is slidably mounted on each support frame. Except for the topmost axial fan module 21, each axial fan module 21 is located between two adjacent support frames 12. The axial fan modules 21 on each support frame 12 can slide horizontally outward relative to that support frame 12, and all axial fan modules 21 have the same direction of movement. Under normal conditions, all axial fan modules 21 are aligned. After a certain axial fan module 21 is slid horizontally outward relative to the support base 12, the rear end of the axial fan module 21 is away from the evaporator 11 inside the cabinet 1, and the axial fan module 21 protrudes outward, which facilitates the maintenance of each axial fan module 21.

[0047] In a further embodiment, refer to Figure 8The supporting base 12 includes a bracket 121 and several rollers 122. A portion of the bracket 121 is connected to one side of the cabinet 1 in the horizontal direction, and the other portion extends horizontally away from the cabinet 1. All the rollers 122 are rotatably connected to the bracket 121 and are spaced apart along the protruding direction of the bracket 121. The bottom of the axial flow fan module 21 is located on the rollers 122. In a specific implementation, the supporting base 12 includes a bracket 121 and several rollers 122. The bracket 121 is a U-shaped frame, and the width of the left and right sides of the bracket 121 can be smaller than the width of the left and right sides of the axial flow fan module 21. A portion of the bracket 121 is connected and fixed to one side of the cabinet 1 in the horizontal direction, and the other portion extends horizontally away from the cabinet 1, with an extension length that can be less than or equal to the front and rear widths of the axial flow fan module 21. There are several rollers 122, all of which are rotatably connected to the bracket 121 and protrude from the upper and lower sides of the supporting base 12. Each roller 122 can rotate independently, and all rollers 122 are spaced apart along the protruding direction of the bracket 121. The bottom of the axial fan module 21 is mounted on and engages with the roller 122, while the top of the axial fan module 21 can contact and engage with the roller 122 of the upper bracket 121. When the axial fan module 21 is pushed or pulled, the roller 122 rotates, causing the axial fan module 21 to slide back and forth relative to the bracket 121, making it easy to pull the axial fan module 21 away from or push it closer to the cabinet. The rollers 122 on each bracket 121 can be divided into two groups, left and right, with the left group and right group maintaining a certain distance. Both groups of rollers 122 contact and engage with the bottom of the axial fan module 21, making the movement of the axial fan module 21 more stable.

[0048] In a further embodiment, refer to Figure 9The bracket 121 has a spring-loaded stop 1201 protruding upwards on the side away from the cabinet 1. The bottom of the axial flow fan module 21 has a recessed limiting groove 202, and the spring-loaded stop 1201 is embedded in the limiting groove 202. The spring-loaded stop 1201 can automatically spring back when pressed. In specific implementation, the bracket 121 has a spring-loaded stop 1201 protruding upwards on the side away from the cabinet 1. The spring-loaded stop 1201 is a block structure that can automatically spring back to its original state after being pressed. A spring is provided between the bottom of the spring-loaded stop 1201 and the bracket 121 to achieve the automatic spring-loaded return of the spring-loaded stop 1201 when pressed. A limiting groove 202 is recessed at the bottom of the axial fan module 21. The shape of the limiting groove 202 matches the shape of the spring-loaded stop 1201. The protruding length of the spring-loaded stop 1201 can be less than the depth of the limiting groove 202. Under normal conditions, the spring-loaded stop 1201 is embedded in the limiting groove 202 at the bottom of the axial fan module 21 to position the axial fan module 21. This restricts the movement of the axial fan module 21 along the bracket 121, preventing it from falling off the cabinet 1. When it is necessary to pull out the axial fan module 21, the bottom of the axial fan module 21 can be raised first to expose the spring-loaded stop 1201. Then, the spring-loaded stop 1201 can be pressed down to the bottom, allowing the axial fan module 21 to be pulled away from the cabinet 1. This is very convenient.

[0049] In one embodiment, reference is made to Figure 10The inter-row air conditioner also includes an electric heating module 4 and a lifting drive assembly 5. The electric heating module 4 is located between the axial fan module 21 and the evaporator 11. The lifting drive assembly 5 is located on one side of the cabinet 1 in the horizontal direction and connected to the electric heating module 4. The electric heating module 4 is used to heat the air, and the lifting drive assembly 5 is used to move the electric heating module 4 up and down to the air inlet 201 of any axial fan module 21. In a specific implementation, the inter-row air conditioner also includes an electric heating module 4 and a lifting drive assembly 5. A gap is left between the rear end of the axial fan module 21 and the evaporator 11 to install the electric heating module 4 and the lifting drive assembly 5. The electric heating module 4 is entirely located between the axial fan module 21 and the evaporator 11 to heat the air and can adjust the airflow temperature output by the axial fan module 21. The electric heating module 4 is designed to be height-adjustable and its lifting movement is controlled by the lifting drive assembly 5, which is located on one side of the cabinet 1 in the horizontal direction and connected to the electric heating module 4. In practical applications, the lifting drive assembly 5 and the electric heating module 4 are connected to the air conditioning control system. The control system can control the lifting drive assembly 5 to move the electric heating module 4 up and down to the air inlet 201 of any axial fan module 21, and control the electric heating module 4 to heat the air at the rear of the corresponding axial fan module 21, thereby adjusting the temperature of the airflow output by the axial fan module 21. For data center server rooms in cold regions with uneven temperatures, the control system can detect temperatures at different heights and control the lifting drive assembly 5 to move the electric heating module 4 up and down in real time to adjust the heating position. Combined with an intelligent adjustment mechanism, this improves cooling efficiency and the overall temperature stability of the server room.

[0050] In a further embodiment, refer to Figure 11The lifting drive assembly 5 includes a second guide rail 51 and a second drive component 52. The electric heating module 4 includes a fixing frame 41 and a heating element 42. The second guide rail 51 extends vertically and is disposed on one side of the cabinet 1 in the horizontal direction. The second drive component 52 is connected to the second guide rail 51. The fixing frame 41 is slidably connected to the second guide rail 51 and connected to the second drive component 52. The heating element 42 is disposed on the fixing frame 41. The second drive component 52 is used to drive the fixing frame 41 to slide along the second guide rail 51 to drive the heating element 42 to move up and down. In a specific implementation, the lifting drive assembly 5 includes a second guide rail 51 and a second drive component 52. The second guide rail 51 is a track structure that extends vertically and is disposed on one side of the cabinet 1 in the horizontal direction. The top end of the guide rail extends beyond the top of the uppermost axial fan module 21, and the bottom end extends beyond the bottom of the lowermost axial fan module 21. There are two second guide rails 51, which are vertically parallel and spaced apart on one side of the cabinet 1. The second driving component 52 is connected to the second guide rail 51. The second driving component 52 can be a motor, which can move along the second guide rail 51 through a lead screw structure. The electric heating module 4 consists of a fixed frame 41 and heating tubes 42. The fixed frame 41 is a frame structure with a hollow center, allowing airflow to pass freely. The two ends of the fixed frame 41 are slidably connected to the second guide rail 51 and connected to the second driving component 52. The heating tubes 42 can be composed of an outer glass tube and an internal heating wire, which can generate heat under the drive of the control system. There are multiple heating tubes 42, and the two ends of each heating tube 42 are fixed to the two ends of the fixed frame 41 respectively. In practical applications, the second driving component 52 can drive the fixed frame 41 to slide along the second guide rail 51, thereby causing the fixed frame 41 to move the heating tubes 42 up and down together. This allows the heating tubes 42 to be moved to the rear end of any axial flow fan module 21, adjusting the output airflow temperature of the axial flow fan module 21.

[0051] The inter-row air conditioner provided in this application embodiment is equipped with a sealing mechanism on each axial fan module of the fan module. The sealing mechanism blocks the air outlet on the corresponding axial fan module when the axial fan module stops abnormally. This can effectively prevent the stopped axial fan module from reversing due to the influence of the surrounding airflow, causing airflow short circuit, and prevent uneven temperature distribution in the computer room. The temperature control effect of the computer room is more stable and reliable.

[0052] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
