Description

Technical Field

[0001] The utility model relates to the technical fields of data centers and servers, and particularly relates to a single-row or single-column modular cabinet with built-in cold and hot channels. Background Art

[0002] With the rapid development of technologies such as artificial intelligence, big data, and cloud computing, computing power has become the core driving force for the digital transformation of all industries. It is estimated that the global computing power scale will grow at a rate of more than 50% in the next few years, and the overall scale will reach 3300 EFlops by 2025. With the high-speed growth of computing power demand, the integration density of cabinet servers is getting higher and higher, and the heat generated by servers is getting larger and larger. The working power of some high-end and high-performance chips has reached hundreds of watts, bringing new challenges and opportunities to the refrigeration and heat dissipation of data center computer rooms.

[0003] Especially for supercomputer data center computer rooms, due to objective factors such as a large number of computing nodes, high density, and large-scale deployment, higher requirements are put forward for the refrigeration and heat dissipation of the computer room. Traditional general data center computer rooms generally have some deficiencies and shortcomings such as low heat exchange efficiency, inaccurate cold source control, and high PUE.

[0004] In the deployment method of existing double-row cabinets, the two rows of cabinets are placed facing each other, and a common space is left in the middle as a closed cold channel (cold pool); when applying single-row or single-column cabinet deployment, the following main disadvantages exist: First, the floor area occupied during deployment of the whole set of solutions is large, especially when deploying high-density supercomputer systems or when the computer room space is relatively insufficient. Second, the spaces of the cold channel and the hot channel are large, which means a reduction in refrigeration efficiency and loss of cold quantity. Third, when deploying the modular cabinet solution of the traditional closed cold / hot channel, the maintenance personnel entering the closed cold channel have to work in a low-temperature, high-wind-force, and high-noise environment for a long time, which has an adverse impact on the physical health of the maintenance personnel. Fourth, the product form of the traditional closed cold / hot channel modular cabinet is relatively fixed, and there is still room for further improvement in terms of convenience and flexibility in deployment, expansion, migration, etc. Summary of the Utility Model

[0033] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0034] As Figure 1 shown, according to the single-row or single-column modular cabinet with built-in cold and hot channels in the embodiment of the present utility model, it includes multiple groups of cabinet groups 1 arranged in columns at intervals and connecting plates 5 arranged at corresponding interval positions; each group of cabinet groups 1 includes multiple cabinet units 2;

[0035] As Figures 2 to 11 shown, each cabinet unit 2 includes a cabinet body 21, a front door panel 22, a rear door panel 23, a front channel top plate 27 and a rear channel top plate 28. The cabinet body 21 has a front panel, a rear panel and two side panels. The adjacent side panels of multiple cabinet units are arranged closely and sequentially in contact. The front channel top plate 27 is vertically fixed to the upper end of the corresponding front door panel 22. One end of the rear channel top plate 28 is vertically fixed to the upper end of the rear door panel 23, and the other end is correspondingly connected to the upper part of the front panel or the rear panel; a communicating cold channel 3 is formed between the front channel top plates 27, the front panels and the front door panels 22 of multiple cabinet units 2, and a communicating hot channel 4 is formed between the rear channel top plates 28, the rear panels and the rear door panels 23. Specifically, the widths of the hot channel 4 and the cold channel 3 are less than 600 mm; both ends of the cold channel 3 and the hot channel 4 are blocked by end side plates 29;

[0036] The connecting plate 5 is a plate of type and its horizontal plate is arranged parallel to the end side plate 29. The vertical plates of the connecting plate are respectively connected to the front door plate 22 and the rear door plate 23 of the adjacent cabinet unit in the same plane to form an inter-column channel connecting the hot channel and the cold channel. An inter-column air conditioner is installed in the inter-column channel. The air inlet of the inter-column air conditioner corresponds to one side of the hot channel, and its air outlet corresponds to one side of the cold channel. The hot air flows into the cold channel after being cooled by the inter-column air conditioner. The cold air flow in the cold channel takes away the heat of the equipment in the cabinet and flows out from the rear end to the hot channel, and circulates in turn.

[0037] Specifically, as Figure 2 , Figure 3 , Figure 9 and Figure 10 , the other ends of the front channel top plate 27 and the rear channel top plate 28 are hermetically butted against the upper ends of the front panel or the rear panel and are arranged flush. A sealing positioning groove can be provided on the panel surface of the front panel or the rear panel. The ends of the front channel top plate 27 and the rear channel top plate 28 can be directly inserted into the sealing positioning and fixing; as Figure 4 , Figure 5 , Figure 7 and Figure 8 , the front channel top plate 27 or the rear channel top plate 28 overlaps on the upper end of the front panel. A sealing positioning groove can be provided at the upper end of the front panel or the rear panel. The lower plate surface of the ends of the front channel top plate 27 and the rear channel top plate 28 can be provided with insertion parts, and can be inserted into the sealing positioning and fixing through the insertion parts, realizing convenience, quickness in deployment / expansion / migration.

[0038] In the present utility model, a computer room can be directly assembled and formed by arranging multiple cabinet units 2 in columns or rows. That is, a communicating cold channel 3 is formed between the front channel top plate 27, the front panel and the front door plate 22, and a communicating hot channel 4 is formed between the rear channel top plate 28, the rear panel and the rear door plate 23. Both ends of the cold channel 3 and the hot channel 4 are blocked by the end side plates 29, which can greatly reduce the space of the cold channel and the hot channel, and then can significantly improve the heat dissipation efficiency and further reduce the PUE of the system.

[0039] In the present utility model, by arranging the modular cabinet units in rows or columns, the cold channel 3 and the hot channel 4 at the front and rear ends are directly formed, significantly reducing the occupied space of the enclosed cold / hot channels, significantly improving the heat dissipation efficiency, being more convenient for deployment / expansion / migration, and also enabling the operation and maintenance personnel to work in a more comfortable computer room environment.

[0040] The utility model can effectively reduce the diffusion of cold source and improve the utilization efficiency of cold source through the cold channels 3 and hot channels 4 formed at the front and rear ends of the modular cabinet unit 2; the closed hot channel directly formed at the rear end can effectively isolate the heat generated by the equipment from the heat in the computer room space, reducing the cross-influence of the heat in the computer room space on it; when the cabinet units are assembled, the closed cold / hot channels directly formed at the front and rear ends can more precisely control the cold source demand and heat conversion in the cabinet, improve the heat dissipation energy efficiency, and reduce the system power consumption.

[0041] In some specific embodiments, the cabinet unit 2 further includes a chassis 24, a front door frame 25 and a rear door frame 26 vertically fixed at the front and rear ends of the chassis 24, and a front door panel 22 and a rear door panel 23 are respectively installed on the front door frame 25 and the rear door frame 26; the cabinet body 21 is placed on the chassis 24, and it can realize the independent expansion and deployment of equipment. As Figure 6 and Figure 11 shown, the front door frame 25 or the rear door frame 26 and the front channel top plate or the rear channel top plate

[0042] In some other specific embodiments, the cabinet group 1 includes a first cabinet group, a second cabinet group and a third cabinet group arranged in sequence. The first cabinet group includes a DC cabinet, a first supercomputer cabinet and a second supercomputer cabinet arranged in sequence; the second cabinet group includes more than two IT cabinets arranged in sequence; the third cabinet group includes a first supercomputer cabinet, a second supercomputer cabinet and a DC cabinet arranged in sequence.

[0043] In a specific embodiment, the front door panel 22, the rear door panel 23, the front channel top plate 27 and the rear channel top plate 29 have the same length along the channel direction, and sealing strips are provided at the corresponding docking positions of the front door panel 22, the rear door panel 23, the front channel top plate 27 and the rear channel top plate 28 of adjacent cabinet units 2.

[0044] In a specific example, it may further include an integrated cable management system, and the cable management system is integrated inside the cabinet unit and is respectively arranged corresponding to the cold channel and the hot channel side. Thus, the cable path is short and tidy, the air flow obstruction is reduced, and the cooling efficiency is improved.

[0045] In another specific example, temperature sensors and air flow sensors are independently arranged in both the cold channel and the hot channel. Thus, the data obtained by the temperature sensors and the air flow sensors can be transmitted to the control system in real time to automatically adjust the operating state of the row-level air conditioner to ensure that the temperature and air flow of each cabinet unit are maintained within the optimal range.

[0046] In some examples, it may further include a detachable sound insulation board, and the sound insulation board is installed on the inner walls of the cold channel and the hot channel. Thus, the noise during operation can be effectively reduced, and the working environment of the data center can be improved.

[0047] In some other examples, the front door panel and the rear door panel of the cabinet unit adopt a double-layer structure, with a dust-proof filter net on the inner layer and an adjustable ventilation panel on the outer layer. Thus, the air circulation volume can be adjusted according to needs, further improving the heat dissipation effect.

[0048] In one example, an integrated fire protection system can also be included. The fire protection system includes a smoke sensor and a gas fire extinguishing device and is arranged in the cold aisle and the hot aisle. Thus, when the smoke sensor detects a fire, the gas fire extinguishing system is automatically activated to extinguish the fire, ensuring the safety of the data center.

[0049] When deploying the cabinet solution of the closed cold / hot aisle according to the embodiment of the present utility model, the operation and maintenance personnel do not need to enter the closed cold aisle, and thus will not work in an environment with low temperature, high wind force and high noise for a long time, ensuring the physical health of the operation and maintenance personnel and reducing the harm caused to the operation and maintenance personnel working for a long time by the inappropriate environment; moreover, the product form is changeable, and the convenience and flexibility in aspects such as deployment, expansion and migration are significantly improved.

[0050] The installation process of the present utility model: place the equipment on the rack, and install the equipment into the cabinet body according to the planned racking scheme and connect various cables. After the equipment is racked, the front and rear door panels of the modular cabinet unit are sequentially fixed to the front door frame and the rear door frame, and the structure is fixed to form a closed cold / hot aisle. Finally, the ends of the cold aisle and the hot aisle are closed.

[0051] The outer surface of the front door panel, which is the appearance surface of the cold and hot aisles of the present utility model, can also be respectively decorated and designed according to the visiting needs, presenting a better aesthetic effect. The solution of the present utility model has a higher deployment density, a higher modularization degree, a more flexible deployment method, can design different deployment schemes according to the scale of the supercomputer and the on-site situation of the computer room, and is more easy to deploy / expand / migrate.

[0052] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
