Description

Technical Field

[0001] This invention relates to the field of prefabricated modular container data center technology, specifically a container data center based on a rooftop air conditioner. Background Technology

[0002] Containerized data centers are prefabricated, integrated data center products designed for outdoor, newly built edge data centers. This solution pre-integrates power distribution, temperature control, cabinetry, management, and fire protection subsystems into a single ISO standard 40-foot module. The data center infrastructure is fully prefabricated and pre-tested in the factory, shipped as a complete container, and installed on-site with minimal setup. Infrastructure deployment can be completed in as little as one day, offering plug-and-play functionality. The product also boasts excellent earthquake, wind, dust, and waterproof performance, supporting direct outdoor deployment and long-term operation.

[0003] The container's external dimensions are: 12.192 meters (40 feet) in length and 2.438 meters (8 feet) in width. It is a standard shipping container size. If it is used as a data center, its width is often a shortcoming because of the width of the maintenance channel in the data center. (1) IT cabinets are usually placed horizontally. Generally, there are two 600mm wide cabinets and a 300mm wide inter-row air conditioner in a row, for a total of 4 rows. One or two rows form a closed hot aisle. The entire container is divided into 3 closed hot aisles. Due to the current horizontal arrangement of the cabinets, the number of IT cabinets is generally 7. Overall, the deployment density of IT cabinets is low. The current width of the hot aisle is 550mm.

[0004] The existing data center layout has the following problems: ①The overall solution has three closed hot aisles, which makes operation and maintenance very inconvenient, requiring people to enter and exit during operation and maintenance. ②There are only 7 IT server racks, and the rack utilization rate is relatively low; ③ Due to the limitation of the 300mm wide inter-row air conditioner, the cooling capacity can only reach 25kw. The air conditioner adopts 3+1 redundancy, and the total cooling capacity is 75kw. Overall, the cooling capacity is still relatively low.

[0005] In summary, traditional solutions are limited by horizontal rack layout and in-row air conditioning design, typically only 7 racks can be deployed in a standard 40-foot container, and multiple closed hot aisles are formed, leading to maintenance difficulties. At the same time, the maximum cooling capacity can only reach 75kW, which cannot meet the needs of high-density computing. Summary of the Invention

[0006] The technical objective of this invention is to provide a container data center based on a rooftop air conditioner to solve the problems of low rack deployment density, inconvenient operation and maintenance, and limited cooling capacity in traditional container data centers.

[0007] The technical task of the present invention is achieved in the following way: a container data center based on a roof-mounted air conditioner, including a container cabin, in which several server racks are arranged longitudinally side by side, and a roof-mounted air conditioner is installed above the server racks. The roof-mounted air conditioner adopts an airflow organization form of downward air supply and upward air return, forming a lower air supply cold channel and an upper air return hot channel with the server racks in the container cabin. The floor of the container cabin is equipped with a cabinet base located below the server rack. Two parallel cabinet rails are installed on the cabinet base. A cabinet slider is installed at the bottom of the server rack. The cabinet slider slides in cooperation with the cabinet rails. Limiting mechanisms are installed at both ends of the cabinet rails.

[0008] Preferably, a heat insulation plate is installed in the gap between the top of the server rack and the roof-mounted air conditioner.

[0009] Preferably, the limiting mechanism includes a limiting base and a limiting slider. The limiting base is installed on the cabinet base and is located at the end of the cabinet guide rail. The limiting slider is located at one end of the limiting base and slides with the limiting base.

[0010] More preferably, a limiting slider wedge is provided at the sliding engagement point between the limiting slider and the limiting base, and a limiting slider cavity is provided inside the limiting slider.

[0011] More preferably, several parallel-arranged limit base slides are symmetrically arranged on the upper and lower sides of the middle position of the limit base, and multiple evenly arranged limit movable blocks are symmetrically arranged on both sides of the middle position of the limit base. The limit movable blocks are arranged one-to-one with the limit base slides and the limit movable blocks slide in cooperation with the limit base slides. Limit damping is provided on the limit base slides.

[0012] More preferably, multiple evenly arranged limiting movable blocks form an arc shape, and a slider limiting pin is provided at one end of the limiting movable block near the limiting base slide.

[0013] Preferably, a sliding sealing plate is provided at the connection between the rack rail and the rack base. The sliding sealing plate is used to fill the gap of the rack rail after the server rack is pushed back.

[0014] More preferably, the sliding cover adopts a chain structure, which can rotate freely in the 0°-90° direction. One end of the sliding cover is welded to one side of the limiting slider, and the other end of the sliding cover hangs freely under the electrostatic floor of the container cabin. When the server rack is working normally, the sliding cover fills the grooves of the rack guide rails. When the server rack is under maintenance, one end of the sliding cover moves with the server rack, and the other end of the sliding cover slides freely under the electrostatic floor. When passing through a 90° bend, it automatically bends and slides down.

[0015] More preferably, the sliding sealing plate is an L-shaped structure composed of several main sealing plates hinged together by connecting plates, an end sealing plate one arranged at one end of the main sealing plate and arranged longitudinally alongside the main sealing plate, and an end sealing plate two arranged at the other end of the main sealing plate and arranged perpendicularly to the main sealing plate. The main sealing plates are respectively hinged to the end sealing plate one and the end sealing plate two by connecting plates.

[0016] More preferably, the first end sealing plate and the second end sealing plate are semi-elliptical, and the main sealing plate is a long sealing plate formed by welding two first end sealing plates or two second end sealing plates longitudinally side by side.

[0017] The container data center based on rooftop air conditioning of the present invention has the following advantages: (I) This invention adopts a standard 40-foot container cabin and achieves high-density deployment in a limited space through innovative top-mounted air conditioning and cabinet layout design. Specifically, 12 standard IT cabinets with a width of 600mm are arranged longitudinally side by side in the cabin; a top-mounted air conditioning unit is set above the cabinet, adopting a new airflow organization form of downward air supply and upward air return, forming a downward air supply cold channel and an upward air return hot channel; the bottom of the cabinet is equipped with a pull-out device, which consists of a slide, a limiting cone and a locking slot, allowing the cabinet to be pulled out during maintenance, extending the maintenance channel from 300mm to 600mm. This solves the problems of low deployment density, inconvenient operation and maintenance and limited cooling capacity of traditional container data center cabinets, greatly improving space utilization and return on investment, and has good application prospects. (ii) This invention relates to novel airflow organization, mobile cabinets, data center architecture design and other processing methods, which break the usage mode of container data centers under standard width, and effectively improve the utilization efficiency of container data centers under standard width. It is an innovative design solution in the field of container data center technology. (III) This invention uses a top-mounted air conditioning unit to replace the traditional in-row air conditioning, and innovatively adopts an airflow organization form of bottom supply and top return air, forming a lower supply air cold channel and an upper return air hot channel in the cabin; and increases the number of IT cabinets to 12, greatly improving space utilization through longitudinal side-by-side layout; at the same time, it designs a unique sliding mechanism composed of guide rails and sliders, which allows the cabinets to be pulled out from their original position during maintenance, expanding the maintenance channel width from 300mm to 600mm, greatly improving the convenience of operation and maintenance, significantly improving the cabinet occupancy rate and space utilization efficiency of standard container data centers, while improving the cooling effect and operation and maintenance experience, providing an innovative solution for the deployment of high-density edge data centers, and has important practical value and promotion significance.

[0018] Therefore, this invention has the characteristics of reasonable design, simple structure, easy processing, small size, convenient use, and multiple uses, and thus has great value for promotion and use. Attached Figure Description

[0022] The following detailed description of a container data center based on a rooftop air conditioner, with reference to the accompanying drawings and specific embodiments, is provided in the specification.

[0023] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0025] As attached Figure 1 , 3 As shown in Figure 4, this embodiment provides a container data center based on a rooftop air conditioner. Its structure includes a container cabin 1, in which several server racks 2 are arranged longitudinally side by side. A rooftop air conditioner 3 is installed above the server racks 2. The rooftop air conditioner 3 adopts a downward air supply and upward air return airflow organization form with the server racks 2 in the container cabin 1 to form a lower air supply cold channel 4 and an upper air return hot channel 5. A rack base 6 is installed on the floor of the container cabin 1, located below the server racks 2. Two parallel rack rails 7 are installed on the rack base 6. A rack slider 8 is installed at the bottom of the server rack 2. The rack slider 8 slides with the rack rails 7. Limiting mechanisms are installed at both ends of the rack rails 7.

[0026] In this embodiment, each server rack 2 is equipped with a rack rail 7, and each rack rail 7 is equipped with two rack bases 6 for mounting the server rack 2. The rack rail 7 is fixed to the rack base 6 (which is welded from rectangular steel tubing) by M5 countersunk hexagonal screws. The server rack 2 is fixed to the rack base 6 by four M5 countersunk hexagonal screws at four different locations, each with four screws. Pulling the server rack 2 out from the maintenance position expands the width of the rear maintenance passage from a first width to a second width, facilitating maintenance.

[0027] As attached Figure 2 As shown, in this embodiment, a hot and cold insulation plate 9 is installed in the gap between the top of the server rack 2 and the top-mounted air conditioner 3.

[0028] As attached Figure 5 , 6As shown in Figures 7 and 8, the limiting mechanism in this embodiment includes a limiting base 10 and a limiting slider 11. The limiting base 10 is mounted on the cabinet base 6 and is located at the end of the cabinet guide rail 7. The limiting slider 11 is located at one end of the limiting base 10 and slides with the limiting base 10. A limiting slider wedge 12 is provided at the sliding engagement point between the limiting slider 11 and the limiting base 10, and a limiting slider cavity 13 is provided inside the limiting slider 11. Several parallel limiting base slides 14 are symmetrically installed on the upper and lower sides of the middle position of the limiting base 10. Several evenly arranged limiting movable blocks 15 are symmetrically installed on both sides of the middle position of the limiting base 10. The limiting movable blocks 15 are arranged one-to-one with the limiting base slides 14 and slide with the limiting base slides 14. Limiting damping 16 is installed on the limiting base slides 14. Multiple evenly arranged limiting movable blocks 15 form an arc shape, and a slider limiting pin 17 is installed at one end of the limiting movable block 15 near the limiting base slide 14.

[0029] In this embodiment, when the limiting slider 11 slides past the limiting movable blocks 15 on both sides of the limiting base 10, the limiting movable blocks 15 automatically retract, and the limiting slider 11 is suddenly released after sliding past, forming a limit; the limiting slider 11 is located at one end of the limiting base 10, and the limiting base 10 is fixed to the cabinet base 6 by two M5 internal hex countersunk screws.

[0030] In this embodiment, when the limiting slider 11 moves forward, the limiting slider wedge 12 first contacts the limiting movable block 15, and the limiting movable blocks 15 on both sides simultaneously retract inward. The limiting slider 11 passes through the limiting movable blocks 15 in sequence. The number of limiting movable blocks 15 can be adjusted according to the force applied. As the limiting slider 11 moves forward, the limiting movable blocks 15 slide into the limiting slider cavity 13, reducing the resistance on the limiting slider 11. A slider limiting pin 17 is installed on the limiting movable block 15, and a limiting base slide 14 is installed on the limiting base 10. They are symmetrically arranged, allowing the limiting movable blocks 15 to move on the set limiting base slide 14. When all the limiting movable blocks 15 have entered the limiting slider cavity 13, the server rack 2 enters the designated position and cannot move forward any further. If you want to return to the original position, you need to push it back with force. The limiting can be completed without a complex mechanical mechanism, which takes up little space and is durable.

[0031] In this embodiment, a sliding sealing plate 18 is installed at the connection between the rack rail 7 and the rack base 6. The sliding sealing plate 18 is used to fill the gap of the rack rail 7 after the server rack 2 is pushed back. The sliding sealing plate 18 adopts a chain structure and can rotate freely in the 0°-90° direction. One end of the sliding sealing plate 18 is welded to one side of the limiting slider 11, and the other end of the sliding sealing plate 18 hangs freely under the anti-static floor of the container cabin 1. When the server rack 2 is working normally, the sliding sealing plate 18 fills the groove of the rack rail 7. When the server rack 2 is under maintenance, one end of the sliding sealing plate 18 moves with the server rack 2, and the other end of the sliding sealing plate 18 slides freely under the anti-static floor. When passing through a 90° bend, it automatically bends and slides down.

[0032] As attached Figure 9 As shown, the sliding sealing plate 18 in this embodiment is an L-shaped structure composed of several main sealing plates 19 hinged together by connecting plates 22, end sealing plates 20 installed at one end of the main sealing plates 19 and arranged longitudinally alongside the main sealing plates 19, and end sealing plates 21 installed at the other end of the main sealing plates 19 and arranged perpendicularly to the main sealing plates 19. The main sealing plates 19 are hinged to the end sealing plates 20 and 21 respectively by connecting plates 22. The end sealing plates 20 and 21 are semi-elliptical, and the main sealing plate 19 is a long sealing plate formed by welding two end sealing plates 20 or two end sealing plates 21 longitudinally side by side.

[0033] This embodiment achieves significant overall benefits through innovative containerized data center design. In terms of space utilization, it increases the capacity from only 7 racks in the traditional solution to 12 standard 600mm wide racks, increasing rack deployment density by 71%, greatly improving space utilization and rack availability, and directly reducing the space cost per unit of computing power.

[0034] In terms of operation and maintenance efficiency, this embodiment uses an original rack pull-out device (including a slide, a limiting cone, and a locking slot) to expand the maintenance channel width from 550mm to 600mm, which solves the inconvenience of operation and maintenance caused by the traditional multi-hot aisle layout. Personnel do not need to frequently enter and exit multiple closed channels, improving maintenance efficiency by about 40% while ensuring operation and maintenance safety.

[0035] In terms of cooling performance, this embodiment adopts a new airflow organization with top-mounted air conditioning that supplies air from the bottom and returns it from the top, replacing the traditional in-row air conditioning. This forms an integrated supply air cold channel and return air hot channel, which not only eliminates local hot spots but also breaks through the traditional 75kW limit in terms of cooling capacity. It can meet the heat dissipation needs of higher-density servers and is expected to support a single rack power density of more than 30kW.

[0036] In terms of economics, the prefabricated modular design of this embodiment significantly reduces deployment costs and time, resulting in a substantial increase in return on investment. Simultaneously, the standardized design facilitates mass production and rapid deployment, possessing significant value for large-scale scalability and providing an innovative solution for edge computing and data center construction.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
