Description

Technical Field

[0001] This utility model relates to the field of server rack technology, specifically to a server rack with a closed hot aisle. Background Technology

[0002] With the rapid development of information technology, the heat dissipation problem of data centers and server racks has become increasingly prominent. Traditional large-scale space cooling methods, such as supplying cool air through raised floors or ceilings, can lower the overall temperature of the space, but they suffer from significant energy waste, low targeting, and often ineffective localized heat dissipation within server racks. Especially in high-density data centers, server equipment operates continuously, generating a large amount of heat. If this heat cannot be dissipated effectively and promptly, it will severely impact the normal operation of servers and network speed.

[0003] Currently, server rack cooling primarily relies on the overall air conditioning system of the data center. This system supplies cool air to the data center, absorbs the heat generated by the servers, and then exhausts the hot air to maintain a suitable temperature. However, this cooling method has several drawbacks. Firstly, the data center air conditioning system needs to run continuously to handle the heat generated by the servers, and its power consumption typically accounts for a large proportion of the total energy consumption of the data center. With the increase in the number of servers and power density, the energy consumption of the air conditioning system will further increase, leading to persistently high operating costs for the data center. This not only increases the economic burden on enterprises but also fails to meet current environmental protection requirements for energy conservation and emission reduction. Secondly, within the data center, cool air delivered from the air conditioning vents mixes with the surrounding hot air as it reaches the server racks. Simultaneously, the hot air exhausted from the servers may also mix with the cool air, preventing sufficient heat exchange between the cool air and the servers and reducing cooling efficiency. This mixing of hot and cold air means that some servers do not receive enough cooling, easily leading to localized overheating and affecting server performance and lifespan. In addition, in order to ensure the normal operation of the server, the air conditioning system in the data center needs to continuously reduce the supply air temperature, which further increases energy consumption. Utility Model Content

[0004] In order to overcome the shortcomings of existing technical solutions, this utility model provides a server rack with a closed hot aisle, which can effectively solve the technical problem of poor heat dissipation in server racks currently used.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A server rack with a closed hot aisle includes a rack body. An internal partition divides the rack body into independent cold air and hot air compartments. Multiple flow-diverting holes are provided on the partition to allow communication between the cold and hot air compartments. A cold air inlet connected to the cold air compartment is located at the top of the rack body. A protrusion is located at the rear of the rack body, with a first inclined surface between the protrusion and the rack body for collecting gas. A hot air outlet connected to the hot air compartment is located in the middle of the protrusion. The hot air outlet is connected to a bent, upward-extending air guide shroud, with a wind pressure sensor installed at the bend of the shroud. A retractable hot air bellows cover is installed at the end of the shroud furthest from the rack body.

[0007] Furthermore, the cabinet has an opening at the front end, and a door is sealed and installed at the opening. The inner wall of the cabinet is provided with a limiting groove for limiting the installation of a partition plate. The partition plate is pushed in from the opening at the front end of the cabinet and fixed by the limiting groove.

[0008] Furthermore, each of the diversion holes is equipped with a detachable sealing plate, which is locked and fixed to the diversion hole by an external thread on the outside.

[0009] Furthermore, the bend of the fairing is provided with a second inclined surface, and the wind pressure sensor is mounted on the second inclined surface.

[0010] Furthermore, a retractable cold air accordion is installed on the top of the cabinet, and one end of the cold air accordion is connected to the cold air chamber via a cold air inlet.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention effectively improves the heat dissipation of the server rack by adding a structure that forms a closed heat dissipation channel inside the rack. The independent design of the cold air chamber and the hot air chamber avoids the mixing of hot and cold air, allowing the cold air to exchange heat more fully with the server, thus improving heat dissipation efficiency. At the same time, the real-time monitoring function of the wind pressure sensor can detect heat dissipation problems in a timely manner, facilitating timely adjustments to ensure the normal operation of the server.

[0022] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-4 As shown, this utility model provides a server rack with a closed hot aisle. The rack mainly divides the interior of the rack 1 into independent cold air chambers 3 and hot air chambers 4 through partitions 2. By using specific air duct design and component layout, a closed hot aisle is formed to achieve efficient heat dissipation of the server while ensuring orderly airflow inside the rack.

[0024] Cabinet 1 serves as the main supporting structure of the entire server rack, providing the installation base for other components. Its front opening facilitates server installation and maintenance. A door 8 is sealed at the front opening, serving to enclose the rack, protect the server equipment, and facilitate server installation, maintenance, and repair. The door 8 is sealed to cabinet 1 to prevent external dust and impurities from entering the rack, while also helping to maintain stable temperature and airflow inside the rack.

[0025] A limiting groove 105 is provided on the inner wall of the cabinet 1 for limiting the installation of the partition plate 2. The partition plate 2 is pushed in from the front opening of the cabinet 1 and fixed by the limiting groove 105, thereby dividing the internal space of the cabinet 1 into a cold air chamber 3 and a hot air chamber 4. This installation method facilitates the installation and removal of the partition plate 2, and the partition plate 2 can be easily removed when maintenance or adjustment of the cabinet interior is required.

[0026] The partition plate 2 has multiple diversion holes 201, which allow the cold air chamber 3 and the hot air chamber 4 to communicate with each other. Each diversion hole 201 is equipped with a removable sealing plate 9, which is locked to the diversion hole 201 by external threads on its outer side. In practical applications, the sealing plate 9 can be selectively removed or installed according to the server's heat dissipation requirements and layout to adjust the number and size of airflow channels between the cold air chamber 3 and the hot air chamber 4, thereby optimizing the heat dissipation effect.

[0027] The top of cabinet 1 is equipped with a cold air inlet 101 that communicates with the cold air chamber 3 for introducing external cold air. A retractable cold air accordion 10 is also installed on the top of cabinet 1, with one end of the accordion 10 connected to the cold air chamber 3 via the cold air inlet 101. The retractable design of the accordion 10 allows for adjustments to the amount of cold air introduced in different installation environments, while preventing dust and debris from entering the cold air chamber 3.

[0028] The rear end of the cabinet 1 is provided with a protrusion 102, and a first inclined surface 103 for collecting gas is provided between the protrusion 102 and the cabinet 1. A hot air outlet 104 communicating with the hot air chamber 4 is provided in the middle of the protrusion 102. This design helps to collect and exhaust the hot air in the hot air chamber 4 from the cabinet.

[0029] The hot air outlet 104 is connected to a bend-upward extending air guide shroud 5. A second inclined surface 501 is provided at the bend of the air guide shroud 5, and a wind pressure sensor 6 is installed on the second inclined surface 501. The wind pressure sensor 6 can monitor the wind pressure inside the air guide shroud 5 in real time so as to adjust the operating status of the cabinet's heat dissipation system in a timely manner.

[0030] A retractable hot air pleated hood 7 is installed at the end of the air deflector 5 away from the cabinet 1. The retractable feature of the hot air pleated hood 7 can be adjusted according to the actual needs of hot air exhaust, while preventing hot air from flowing back into the environment around the cabinet, thus improving heat dissipation efficiency.

[0031] During installation, the server components are primarily housed in the hot air chamber 4. In use, external cold air enters the cold air chamber 3 through the cold air inlet 101 at the top of the cabinet 1, and then enters the hot air chamber 4 through the diversion holes 201 on the partition plate 2. In the hot air chamber 4, the cold air exchanges heat with the heat generated by the server, absorbing heat and becoming hot air. Guided by the protrusion 102 and the first inclined surface 103, the hot air converges at the hot air outlet 104 and is discharged upwards through the guide shroud 5. During the hot air discharge process, the air pressure sensor 6 monitors the air pressure in real time to promptly detect and adjust for any abnormal heat dissipation. The retractable hot air bellows shroud 7 and cold air bellows shroud 10 can extend and retract according to the actual installation situation, ensuring smooth airflow.

[0032] Compared to traditional technologies, this solution effectively improves the heat dissipation of the server rack by adding a structure that forms a closed heat dissipation channel within the cabinet 1. The independent design of the cold air chamber 3 and the hot air chamber 4 avoids the mixing of hot and cold air, allowing the cold air to exchange heat more fully with the server, thus improving heat dissipation efficiency. Simultaneously, the real-time monitoring function of the wind pressure sensor 6 can promptly detect heat dissipation problems, facilitating timely adjustments and ensuring the normal operation of the server.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
