Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and particularly to a cabinet. Background Art

[0002] With the development and progress of communication technologies and the continuous growth of the network broadband market and traffic volume, the power density of each device in the computer room is getting larger and larger, and the heat generated by the devices is also getting larger and larger. Research shows that in a data center or enclosed cabinet with unreasonable design, 60% of the cold air supply of the cabinet air conditioner is wasted due to unreasonable air flow organization. Therefore, the hot aisle structure data center often faces the phenomenon of mixing of hot and cold air. At present, in order to prevent this phenomenon from occurring, false panels and partitions are usually used in the cabinet to divide it into hot and cold aisles. However, since the hot aisle is under positive pressure and the cold aisle is under negative pressure, the hot air under positive pressure is forced through the equipment installation gaps, cable routing holes in the cabinet, etc. to the local negative pressure area of the cold aisle for mixing. Therefore, good hot and cold isolation cannot be achieved. Summary of the Invention

[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0038] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "a plurality of" means two or more unless otherwise specifically defined.

[0039] Referring to Figure 1 or Figure 2 or Figure 3 , an embodiment of the present invention provides a cabinet air supply system, which includes a chassis 10, a cabinet air conditioner 20, a cold air duct assembly 30 and a hot air duct assembly 40. Among them, the chassis 10 refers to a device for accommodating equipment. In this embodiment, the chassis is a 5G integrated device, and the 5G integrated device may include a plurality of 5G devices. The cold air duct assembly 30 is a component for receiving and conveying cold air. The hot air duct assembly 40 is a component for receiving and conveying hot air.

[0040] Specifically, an air outlet 101 and an air inlet 102 are provided on the chassis, an air outlet 201 and an air inlet 202 are provided on the cabinet air conditioner 20, a cold air duct inlet 301 and a cold air duct outlet 302 are provided on the cold air duct assembly 30, and a hot air duct inlet 401 and a hot air duct outlet 402 are provided on the hot air duct assembly 40; the cold air duct inlet 301 is connected to the air outlet 201 of the cabinet air conditioner 20; the cold air duct outlet 302 is connected to the air inlet 102 of the chassis, the hot air duct inlet 401 is connected to the air outlet 101 of the chassis, and the hot air duct outlet 402 is connected to the air inlet 202 of the cabinet air conditioner 20. By providing the cold air duct assembly 30 and the hot air duct assembly 40, the cold air output from the cabinet air conditioner - the cold air inlet of the chassis - the hot air outlet of the chassis - the hot air inlet of the cabinet air conditioner is formed into a closed independent circulation system inside, thus avoiding the mixing of hot and cold air.

[0041] Understandably, the cold air duct inlet 301 on the cold air duct assembly 30 receives the cold air output from the air outlet 201 of the cabinet air conditioner 20; then the cold air is transmitted to the air inlet 102 of the chassis 10 through the cold air duct outlet 302, and is converted into hot air due to the heat dissipation of the equipment inside the chassis 10, and then is transmitted out from the air outlet 101 of the chassis 10. Further, the hot air duct inlet 401 on the hot air duct assembly 40 receives the hot air transmitted out from the air outlet 101 of the chassis, and then transmits the hot air to the air inlet 202 of the cabinet air conditioner 20 through the hot air duct outlet 402, and then the refrigerant inside the rack air conditioner performs heat conversion to generate cold air. An internal closed independent circulation system is formed among the chassis 10, the cabinet air conditioner 20, the cold air duct assembly 30 and the hot air duct assembly 40, thus avoiding the mixing of hot and cold air and the waste of cold air supply of the cabinet air conditioner.

[0042] Preferably, in this embodiment, the air volume of the chassis 10 matches the air volume of the rack air conditioner 20: the air volumes of both the chassis 10 and the rack air conditioner 20 are adjustable, and the change of the specific traffic volume will cause corresponding changes in the power consumption and air volume of the chassis 10. Therefore, in the cabinet air supply system of this embodiment, according to the changes in the power consumption and air volume of the chassis 10, the air volume of the rack air conditioner 20 is adjusted, so as to achieve the purpose of matching the air volume of the chassis and the air volume of the rack air conditioner.

[0043] In this embodiment, the cold air duct inlet 301 of the cold air duct assembly 30 is connected to the air conditioner outlet 201 of the cabinet air conditioner 20; the cold air duct outlet 302 of the cold air duct assembly 30 is connected to the chassis inlet 102 of the chassis 10, and the hot air duct inlet 401 of the hot air duct assembly 40 is connected to the chassis outlet 101 of the chassis 10, and the hot air duct outlet 402 of the hot air duct assembly 40 is connected to the air conditioner inlet 202 of the cabinet air conditioner 20; thereby forming an internally sealed independent circulation system, avoiding the mixing of hot and cold air and the waste of cold air supply by the air conditioner, and solving the problem of hot and cold air flow management.

[0044] Further, referring to Figure 1 or Figure 2 or Figure 3 , there are at least two chassis, and each chassis 10 is provided with a chassis outlet 101 and a chassis inlet 102. It can be understood that the number of chassis can be customized according to actual situations. It should be noted that, in order to facilitate the connection of the chassis outlet 101 of each chassis 10 to the corresponding cold air duct inlet 301 of the cold air duct assembly 30, and the connection of the chassis inlet 102 of each chassis 10 to the corresponding hot air duct outlet 402 of the hot air duct assembly 40. In this embodiment, each chassis 10 is arranged in the same vertical direction.

[0045] The number of cold air duct outlets 302 on the cold air duct assembly 30 is the same as the number of chassis 10, and each cold air duct outlet 302 is connected to a chassis inlet 102; the number of hot air duct inlets 401 on the hot air duct assembly 40 is the same as the number of chassis 10, and each hot air duct inlet 401 is connected to a chassis outlet 101.

[0046] Understandably, since there is only one chassis air inlet 102 and one chassis air outlet 101 on each chassis 10, while multiple cold air duct outlets 302 can be provided on one cold air duct assembly 30, and multiple hot air duct inlets 401 can be provided on one hot air duct assembly 40. Therefore, when the number of chassis 10 is at least two, the number of cold air duct outlets 302 on the cold air duct assembly 30 is the same as the number of chassis 10, and the number of hot air duct inlets 401 on the hot air duct assembly 40 is the same as the number of chassis 10. Each of the cold air duct outlets 302 is connected to one of the chassis air inlets 102, and each of the hot air duct inlets 401 is connected to one chassis air outlet 101. Thus, each chassis can form a closed and independent circulation system with the cabinet air conditioner 20, the cold air duct assembly 30, and the hot air duct assembly 40, ensuring that the formed closed and independent circulation system is not affected by the number of chassis, and avoiding the mixing of hot and cold air and the waste of cold air supply from the air conditioner.

[0047] Further, referring to Figure 4 or Figure 5 , the cold air duct outlet 302 is provided on the side of the cold air duct assembly 30, and the cold air duct outlet 302 is connected to the chassis air inlet 102 through a first connecting steel ring 501.

[0048] Among them, the first connecting steel ring 501 refers to the steel ring used to connect the chassis air inlet 102 and the cold air duct outlet 302. Optionally, the material of the first connecting steel ring 501 is low-carbon steel. The first connecting steel ring 501 is adapted to the cold air duct outlet 302. Understandably, the cold air duct assembly 30 may be a soft form that cannot be directly installed and connected to other components. Therefore, the first connecting steel ring 501 is needed to connect the chassis air inlet 102 and the cold air duct outlet 302. Specifically, first fix the first connecting steel ring 501 in the cold air duct outlet 302 that is adapted to it, and then use a connecting piece to fasten the first connecting steel ring 501 in the chassis air inlet 102 and the cold air duct outlet 302.

[0049] The cold air duct inlet 301 is provided at the bottom of the cold air duct assembly 30, and the air conditioner outlet 201 is provided at the top of the cabinet air conditioner 20. Understandably, since the cabinet air conditioner 20 is provided at the bottom of the cold air duct assembly 30, therefore, setting the cold air duct inlet 301 at the bottom of the cold air duct assembly 30 and the air conditioner outlet 201 at the top of the cabinet air conditioner 20 can better realize the connection between the cold air duct inlet 301 and the air conditioner outlet 201.

[0050] The air inlet 301 of the cold air duct is connected to the air outlet 201 of the air conditioner through the second connecting steel ring 502. Among them, the second connecting steel ring 502 refers to the steel ring used to connect the air outlet 201 of the air conditioner and the air inlet 301 of the cold air duct. Similarly, the material of the second connecting steel ring 502 is low-carbon steel. The second connecting steel ring 502 is adapted to the air inlet 301 of the cold air duct. The cold air duct assembly 30 may be a soft form that cannot be directly installed and connected to other components. Therefore, the second connecting steel ring 502 is required to connect the air outlet 201 of the air conditioner and the air inlet 301 of the cold air duct. Specifically, first fix the second connecting steel ring 502 in the air inlet 301 of the cold air duct that is adapted to it, and then use a connecting piece to fasten the second connecting steel ring 502 in the air outlet 201 of the air conditioner and the air inlet 301 of the cold air duct.

[0051] Furthermore, the cabinet air supply system further includes a first mounting plate and a first mounting ring. Among them, the first mounting plate is a part formed by bending sheet metal. In this embodiment, the material of the first mounting plate is low-carbon steel, which is used to ensure that the cold air duct assembly 30 is not easily deformed and further fasten the connection between the cold air duct outlet 302 and the chassis air inlet 102. The first mounting ring is a steel ring for fixing the first mounting plate on the cold air duct assembly 30.

[0052] The first mounting ring is arranged at the top of the cold air duct assembly 30 and is adjacent to the cold air duct outlet 302. One end of the first mounting plate is connected to the first mounting ring, and the other end of the first mounting plate is connected to the first connecting steel ring 501.

[0053] Specifically, when there is only one cold air duct outlet 302 on the cold air duct assembly 30, the cold air duct outlet 302 is arranged on the side near the top of the cold air duct assembly 30. Specifically, first fasten the first mounting ring to the top of the cold air duct assembly 30 through a connecting piece; then, firmly connect the upper end of the first mounting plate to the first mounting ring through a connecting piece, and firmly connect any side end adjacent to the upper end of the first mounting plate to the first connecting steel ring 501 fixed to the cold air duct outlet 302, so as to fix the first mounting plate on the cold air duct assembly 30. Optionally, the connecting piece can be a bolt. Preferably, in this embodiment, two first mounting plates are provided and the two first mounting plates are symmetrically distributed and fixed on the left and right sides of the cold air duct assembly 30; to better ensure that the cold air duct assembly 30 is not easily deformed and fasten the connection between the cold air duct outlet 302 and the chassis air inlet 102.

[0054] Furthermore, refer to Figure 4 or Figure 5, the air outlet 302 of the cold air duct is arranged on the side of the cold air duct assembly 30, and each air outlet 302 of the cold air duct is connected to the corresponding air inlet 102 of the chassis through a first connecting steel ring 501.

[0055] Specifically, when there are at least two chassis 10, that is, when there are at least two air outlets 302 of the cold air duct on the cold air duct assembly 30, each air outlet 302 of the cold air duct is connected to the corresponding air inlet 102 of the chassis through a first connecting steel ring 501. In this embodiment, there are two chassis 10, and there are two air outlets 302 of the cold air duct on the cold air duct assembly 30.

[0056] The cabinet air supply system includes a second mounting plate 602 and a second mounting ring 702. The second mounting ring 702 surrounds the cold air duct assembly 30 and is arranged adjacent to the air outlet 302 of the cold air duct located in the middle of the cold air duct assembly 30. One end of the second mounting plate 602 is connected to the second mounting ring 702, and the other end of the second mounting plate 602 is connected to the first connecting steel ring 501. Among them, the air outlet 3022 of the cold air duct located in the middle of the cold air duct assembly 30 is specifically the air outlet of the cold air duct that is not located at the top and bottom of the cold air duct assembly 30.

[0057] The cabinet air supply system further includes a third mounting plate 603 and a third mounting ring 703. The third mounting ring 703 is arranged on the top of the cold air duct assembly 30 and is arranged adjacent to the air outlet 3021 of the cold air duct located at the top of the cold air duct assembly 30. One end of the third mounting plate 603 is connected to the third mounting ring 703, and the other end of the third mounting plate 603 is connected to the first connecting steel ring 501 corresponding to the air outlet 3021 at the top.

[0058] It can be understood that the second mounting plate 602 and the third mounting plate 603 are the same as the above-mentioned first mounting plate. The second mounting ring 702 and the third mounting ring 703 are the same as the above-mentioned first mounting ring.

[0059] In this embodiment, when there are two air outlets 302 on the cold air duct assembly 30, one air outlet 3021 is arranged on the side of the cold air duct assembly 30 near the top, and the other air outlet 3022 is arranged in the middle of the cold air duct assembly 30. The third mounting plate 603 and the third mounting ring 703 are arranged on the side of the cold air duct assembly 30 near the top, which are the same as the first mounting plate and the first mounting ring 701. Moreover, the positions and connection methods of the third mounting plate 603 and the third mounting ring 703 on the cold air duct assembly 30 are the same as the positions and connection methods of the first mounting plate 601 and the first mounting ring on the cold air duct assembly 30 in the above steps, and no redundant description will be made here.

[0060] The second mounting plate 602 and the second mounting ring 702 are arranged in the middle of the cold air duct assembly 30. Specifically, first, the second mounting ring 702 is fixedly surrounded on the cold air duct assembly 30 by bolts and is adjacent to the cold air duct outlet 3022 located in the middle of the cold air duct assembly 30; then one end of the second mounting plate 602 is firmly connected to the second mounting ring 702 by bolts, and any side end of the second mounting plate 602 adjacent to the upper end is firmly connected to the first connecting steel ring 501 fixed at the cold air duct outlet 3022; thereby realizing the fixation of the second mounting plate 602 in the middle of the cold air duct assembly 30. Similarly, two second mounting plates 602 are provided and are symmetrically distributed and fixed on the left and right sides in the middle of the cold air duct assembly 30; so as to better ensure that the cold air duct assembly 30 is not easily deformed and to tighten the connection between the cold air duct outlet 302 and the chassis air inlet 102.

[0061] Further, referring to Figure 6 or Figure 7 , both the hot air duct inlet 401 and the hot air duct outlet 402 are arranged on one side of the hot air duct assembly 40, and the hot air duct inlet 401 is located above the hot air duct outlet 402.

[0062] Specifically, since the rack air conditioner 20 is arranged below the chassis 10, the hot air duct inlet 401 on the hot air duct assembly 40 is connected to the chassis air outlet 101 of the chassis 10, and the hot air duct outlet 402 is connected to the air conditioner inlet 202 of the rack air conditioner 20. Therefore, the hot air duct inlet 401 is arranged above the hot air duct outlet 402 to better realize the connection between the hot air duct inlet 401 and the chassis air outlet 101, and the connection between the hot air duct outlet 402 and the air conditioner inlet.

[0063] The hot air duct inlet is connected to the chassis air outlet 101 through a third connecting steel ring 503, and the hot air duct outlet 402 is connected to the air conditioner inlet 202 through a fourth connecting steel ring 504. Among them, the third connecting steel ring 503 refers to the steel ring used to connect the chassis air outlet 101 and the hot air duct inlet 401. The fourth connecting steel ring 504 refers to the steel ring used to connect the air conditioner inlet 202 and the hot air duct outlet 402. The materials of the third connecting steel ring 503 and the fourth connecting steel ring 504 are both low-carbon steel. The third connecting steel ring 503 needs to be adapted to the hot air duct inlet 401; the fourth connecting steel ring 504 needs to be adapted to the hot air duct outlet 402.

[0064] Specifically, the hot air duct assembly 40 may be a soft form that cannot be directly installed and connected to other components. Therefore, a third connecting steel ring 503 is required to connect the chassis air outlet 101 and the hot air duct air inlet 401, and a fourth connecting steel ring 504 is used to connect the air conditioner air inlet 202 and the hot air duct air outlet 402. Specifically, first fix the third connecting steel ring 503 in the hot air duct air inlet 401 that fits it, and then use a connecting piece to fasten the chassis air outlet 101 and the hot air duct air inlet 401. Also, first fix the fourth connecting steel ring 504 in the hot air duct air outlet 402 that fits it, and then use a connecting piece to fasten the air conditioner air inlet 202 and the hot air duct air outlet 402, so as to ensure that there is an accurate connection without gaps between the chassis air outlet 101 and the hot air duct air inlet 401, and between the air conditioner air inlet 202 and the hot air duct air outlet 402, and the connection method is simple and convenient. The connecting piece can be a bolt.

[0065] Furthermore, the cabinet air supply system further includes a fourth mounting plate and a fourth mounting ring.

[0066] Among them, the fourth mounting plate is a part formed by bending sheet metal. In this embodiment, the material of the fourth mounting plate is low-carbon steel, which is used to ensure that the hot air duct assembly 40 is not easily deformed and further fasten the connection between the hot air duct air outlet 402 and the air conditioner air inlet 202. The fourth mounting ring is a steel ring for fixing the fourth mounting plate on the hot air duct assembly.

[0067] The fourth mounting ring is arranged at the top of the hot air duct assembly 40 and is adjacent to the hot air duct air inlet 401. One end of the fourth mounting plate is connected to the fourth mounting ring, and the other end of the fourth mounting plate is connected to the third connecting steel ring 503.

[0068] Specifically, when there is only one hot air duct air inlet 401 on the hot air duct assembly 40, the hot air duct air inlet 401 is arranged on the side of the hot air duct assembly 40 near the top. Specifically, first fasten the fourth mounting ring to the top of the hot air duct assembly 40 through a connecting piece; then, use a connecting piece to firmly connect the upper end of the fourth mounting plate to the fourth mounting ring, and connect any side end adjacent to the upper end of the fourth mounting plate to the third connecting steel ring 503 fixed at the hot air duct air inlet 401, so as to fix the fourth mounting plate on the hot air duct assembly 40. Preferably, in this embodiment, two fourth mounting plates are provided and the two fourth mounting plates are symmetrically fixed on the left and right sides of the hot air duct assembly 40; to better ensure that the hot air duct assembly 40 is not easily deformed and fasten the connection between the hot air duct air inlet 401 and the chassis air outlet 101. The connecting piece can be a bolt.

[0069] Furthermore, referring to Figure 6 or Figure 7, the air inlet 401 of the hot air duct is arranged on the side of the hot air duct assembly 40, and each air inlet 401 of the hot air duct is connected to the air outlet 101 of the chassis through a third connecting steel ring 503.

[0070] Specifically, when there are at least two chassis 10, that is, when there are at least two air inlets 401 on the hot air duct assembly 40, each air inlet 401 of the hot air duct is connected to the corresponding air outlet 101 of the chassis through a third connecting steel ring 503. In this embodiment, there are two chassis 10, and there are two air inlets 401 on the hot air duct assembly 40.

[0071] The cabinet air supply system includes a fifth mounting plate 605 and a fifth mounting ring 705. The fifth mounting ring 705 surrounds the hot air duct assembly 40 and is arranged adjacent to the air inlet 401 in the middle of the hot air duct assembly 40. One end of the fifth mounting plate 605 is connected to the fifth mounting ring 705, and the other end of the fifth mounting plate 605 is connected to the third connecting steel ring 503;

[0072] The cabinet air supply system further includes a sixth mounting plate 606 and a sixth mounting ring 706. The sixth mounting ring 706 is arranged on the top of the hot air duct assembly 40 and is arranged adjacent to the air inlet 4011 at the top of the hot air duct assembly 40. One end of the sixth mounting plate 606 is connected to the sixth mounting ring 706, and the other end of the sixth mounting plate 606 is connected to the third connecting steel ring 503.

[0073] It can be understood that the fifth mounting plate 605 and the sixth mounting plate 606 are the same as the above-mentioned fourth mounting plate. The fifth mounting ring 705 and the sixth mounting ring 706 are the same as the above-mentioned fourth mounting ring.

[0074] In this embodiment, when there are two air inlets 401 on the hot air duct assembly 40, one air inlet 4011 is arranged on the side of the hot air duct assembly 40 near the top, and the other air inlet 4012 is arranged in the middle of the hot air duct assembly 40. The sixth mounting plate 606 and the sixth mounting ring 706 are arranged on the side of the hot air duct assembly 40 near the top, which is the same as the fourth mounting plate and the fourth mounting ring. Moreover, the positions and connection methods of the sixth mounting plate 606 and the sixth mounting ring 706 on the hot air duct assembly 40 are the same as the positions and connection methods of the fourth mounting plate and the fourth mounting ring on the hot air duct assembly in the above steps, and no redundant description will be made here.

[0075] The fifth mounting plate 605 and the fifth mounting ring 705 are arranged in the middle of the hot air duct assembly 40. Specifically, first, the fifth mounting ring 705 is fixedly surrounded on the hot air duct assembly 40 through a connecting piece and is adjacent to the hot air duct air inlet 4012 located in the middle of the hot air duct assembly 40; then one end of the fifth mounting plate 605 is firmly connected to the fifth mounting ring 705 through a connecting piece, and any side end of the fifth mounting plate 605 adjacent to the upper end is firmly connected to the third connecting steel ring 503 fixed at the hot air duct air inlet 4012; thereby realizing the fixation of the fifth mounting plate 605 in the middle of the hot air duct assembly 40. Similarly, two fifth mounting plates 605 are provided and are symmetrically distributed and fixed on the left and right sides in the middle of the hot air duct assembly 40; so as to better ensure that the hot air duct assembly 40 is not easily deformed and to tighten the connection between the hot air duct air inlet 401 and the chassis air outlet 101. The connecting piece can be a bolt.

[0076] Further, referring to Figure 4 or Figure 6 , the cavity 303 of the cold air duct assembly 30 is made of nylon canvas material, and the cavity 403 of the hot air duct assembly 40 is made of nylon canvas material.

[0077] Specifically, since the nylon canvas air duct is a soft form, therefore, the cavity 303 of the cold air duct assembly 30 and the cavity 403 of the hot air duct assembly 40 are both made of nylon canvas material, so as to be more convenient for connecting with the rack air conditioner 20 and the chassis 10; and the fitting tolerance is large, solving the difficult problem of difficult fitting of the air duct made of metal structure. In addition, the thermal conductivity coefficient of the nylon canvas material is much lower than that of the metal casing, thereby reducing the heat leakage through space and radiation heat leakage and having no impact on the energy consumption of the data computer room.

[0078] Preferably, in this embodiment, heat insulation materials are respectively coated in the cavity 303 of the cold air duct assembly 30 and the cavity 403 of the hot air duct assembly 40, which can further reduce the radiation heat leakage of the materials.

[0079] The first connecting steel ring 501 is sewn and bonded at the cold air duct air outlet 302 of the cold air duct assembly 30, and the second connecting steel ring 502 is sewn and bonded at the cold air duct air inlet 301.

[0080] The third connecting steel ring 503 is sewn and bonded at the hot air duct air inlet 401, and the fourth connecting steel ring 504 is sewn and bonded at the hot air duct air outlet 402.

[0081] Specifically, since the cavities of the cold air duct assembly 30 and the hot air duct assembly 40 are both made of nylon canvas, which is a soft form, the cold air duct assembly 30 and the hot air duct assembly 40 cannot be directly installed and connected to other components. Therefore, the first connecting steel ring 501 needs to be sewn and bonded at the cold air outlet 302 of the cold air duct assembly 30, and the second connecting steel ring 502 is sewn and bonded at the cold air inlet 301. The third connecting steel ring 503 is sewn and bonded at the hot air inlet 401, and the fourth connecting steel ring 504 is sewn and bonded at the hot air outlet 402, so as to ensure the formation of a closed and independent circulation system.

[0082] The present invention also provides a cabinet, referring to Figure 8 It includes a rack 1001 and the above-mentioned cabinet air supply system, and the cabinet air supply system is arranged inside the rack 1001. Among them, the rack 1001 refers to the body for placing the cabinet air supply system. It can be understood that the size of the rack 1001 can be set according to the actual size of the cabinet air supply system, and the size of the rack 1001 needs to be adapted to the size of the cabinet air supply system. Preferably, in this embodiment, the size of the rack 1001 is 19 inches.

[0083] In this embodiment, the materials and processing costs of the cabinet are much lower than those of metal, and the installation and matching are simple. There is no need to form a closed hot and cold channel with front and rear doors, and the front and rear door panels can be omitted, which reduces the cost compared with traditional micro DC closed cabinets. Additionally, since the cabinet air supply system is an independent and closed circulation system, the hot channel will not affect the expansion of other devices (such as batteries, power supplies, etc.) on the rack.

[0084] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
