Description

Technical Field

[0001] This utility model relates to the field of central computer room technology, specifically a modular central computer room ventilation device with multi-level heat dissipation. Background Technology

[0002] Modular data center is a data center solution built on the modular design concept. It standardizes and prefabricates the subsystems such as power supply, cooling, cabinets, and monitoring in traditional data center construction, forming independent modular units. Through rapid on-site assembly, it enables rapid deployment, flexible expansion, and efficient management of the data center.

[0003] Since servers and other equipment are installed in racks, which are then stored in the computer room, the cooling capacity distributed by the air conditioner or central air conditioning in the computer room is used for unified heat exchange. Although the computer room can form an independent space to avoid temperature interference from the external environment, the temperature in each rack is inconsistent due to the difference in the type or number of equipment. The current unified heat exchange method cannot accurately and reasonably distribute the cooling capacity, resulting in poor heat exchange effect.

[0004] Therefore, in order to solve the above problems, a modular central computer room ventilation device with multi-stage heat dissipation is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a modular central computer room ventilation device with multi-level heat dissipation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular central computer room ventilation device with multi-stage heat dissipation, comprising a base, a machine room fixedly installed on the upper side of the base, a partition fixedly installed on the top inner side of the machine room, the partition separating the internal space of the machine room to form an upper negative pressure chamber and a lower equipment chamber, an exhaust duct connected to the negative pressure chamber fixedly installed on the upper side of the machine room, an exhaust fan connected to the upper side of the exhaust duct, a uniform distribution chamber provided inside the base, and an air inlet duct connected to the uniform distribution chamber fixedly installed on the rear side of the base; Two rows of cabinets are placed on the upper side of the base. The base and partition are equipped with adjustment components that align the upper and lower ends of the cabinets respectively. A control component is installed outside the computer room. The two adjustment components that align the upper and lower ends of each cabinet are connected and assembled with the same control component. A conveyor channel is fixedly installed inside the computer room. The conveyor channel connects the cabinets and the corresponding adjustment components on the upper side.

[0007] Specifically, the adjustment assembly includes a fan-shaped baffle, a drive shaft, and a fan-shaped through slot. The drive shaft for aligning the cabinet is rotatably mounted inside the uniform distribution chamber and the negative pressure chamber via a bearing seat. One end of the drive shaft near the cabinet extends out of the base and is fixedly mounted with a fan-shaped baffle. Multiple sets of fan-shaped through slots for aligning the cabinet are opened on the top of the base.

[0008] Furthermore, the number of fan-shaped through slots in each group is 2 to 3, and the fan-shaped through slots in each group are distributed in a circle around the drive shaft. The number and position of the fan-shaped baffles match the number of fan-shaped through slots.

[0009] Specifically, the control components include a dual-output shaft motor, a synchronous pulley, and a synchronous belt. The dual-output shaft motor aligned with the cabinet is fixedly installed outside the machine room. The output end and drive shaft of the dual-output shaft motor are both fixedly installed with synchronous pulleys. A synchronous belt is sleeved between the two synchronous pulleys located at the same end of the cabinet.

[0010] Specifically, the bottom of the cabinet is fitted with a rubber frame, and the bottom of the rubber frame abuts against the upper surface of the base during use.

[0011] Specifically, the cabinet has an integral U-shaped cavity on the front, back, and bottom sides. A hollow support plate connected to the U-shaped cavity is fixedly installed inside the cabinet. An air inlet aligned with the lower adjustment component is opened at the bottom of the cabinet. Ventilation holes are evenly distributed on the top of the hollow support plate. Air outlets are evenly distributed on the side wall of the cabinet near the computer room. An air outlet is also provided above the hollow support plate. A temperature sensor is fixedly installed on the top inner side of the cabinet. A cabinet door is hinged on the side of the cabinet away from the air outlet.

[0012] Specifically, the conveying channel includes a rectangular channel and a bucket-shaped channel that are connected and assembled. The bucket-shaped channel is fixedly assembled with the partition and is aligned with the upper adjustment component. The rectangular channel has a rectangular groove aligned with the air outlet on the side near the cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are: Primary heat dissipation measures: By modifying the cabinet, the cooling capacity entering from the lower air inlet can be distributed and output in a targeted manner through the U-shaped cavity, hollow support plate, and ventilation holes, which can exchange heat with the equipment placed on each layer of the cabinet. Secondary heat dissipation measures: Based on the temperature inside each rack, the air intake and exhaust volume of the rack can be precisely adjusted through control and adjustment components to meet heat exchange requirements; Three-stage heat dissipation measures: the airflow formed by the uniform distribution chamber, cabinet, conveyor channel and negative pressure chamber has a more reasonable path, so that the airflow in the cabinet does not interfere with each other.

[0014] Based on the above structural modifications, cold energy can be delivered and controlled in a targeted manner, and the utilization rate of cold energy and the heat dissipation effect can be improved by organizing and managing airflow in multiple stages. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1 and Figure 2 This utility model provides a modular central computer room ventilation device with multi-level heat dissipation, including a base 1, a machine room 2 fixedly installed on the upper side of the base 1, and a double door on the front side of the machine room 2 to facilitate personnel entry and exit. The base 1 and the machine room 2 form an independent space for placing equipment.

[0019] A partition 9 is fixedly installed on the top of the inner side of the machine room 2. The partition 9 separates the internal space of the machine room 2 to form an upper negative pressure chamber and a lower equipment chamber. An exhaust duct 8 connected to the negative pressure chamber is fixedly installed on the upper side of the machine room 2. An exhaust fan 7 is connected to the upper side of the exhaust duct 8. When in use, the upper end of the exhaust fan 7 is connected to the central exhaust pipe to exhaust the air entering the negative pressure chamber to the outside.

[0020] The base 1 has a uniform distribution cavity inside. An air inlet pipe 17 connected to the uniform distribution cavity is fixedly installed on the rear side of the base 1. When in use, the rear end of the air inlet pipe 17 is connected to the central air inlet pipe to deliver the cooling capacity to the uniform distribution cavity. In addition, in order to ensure the support strength of the base 1, support columns 18 are uniformly fixedly installed inside the uniform distribution cavity.

[0021] Two rows of server racks 4 are placed on the upper side of the base 1. The server racks 4 are used to store servers and other equipment in layers. The base 1 and the partition 9 are equipped with adjustment components that are respectively aligned with the upper and lower ends of the server racks 4. A control component is set on the outside of the computer room 2. The two adjustment components aligned with the upper and lower ends of each server rack 4 are connected and assembled with the same control component. A conveying channel is fixedly installed inside the computer room 2. The conveying channel connects the server racks 4 and the corresponding adjustment components on the upper side. Each control component can adjust the two adjustment components corresponding to a server rack 4, and simultaneously adjust the air intake and exhaust volume. The cooling capacity enters the server rack 4 from the lower adjustment component and enters the negative pressure chamber from the conveying channel and the upper adjustment component.

[0022] Specifically, the adjustment components include a fan-shaped baffle 13, a drive shaft 14, and a fan-shaped through slot 15. The drive shaft 14, aligned with the cabinet 4, is rotatably mounted inside the uniform distribution chamber and the negative pressure chamber via a bearing seat. One end of the drive shaft 14, near the cabinet 4, extends out of the base 1 and is fixedly mounted with the fan-shaped baffle 13. Multiple sets of fan-shaped through slots 15 aligned with the cabinet 4 are opened on the top of the base 1. The two drive shafts 14 aligned vertically with the cabinet 4 can be driven simultaneously by the control components, thereby rotating the fan-shaped baffle 13 and changing the area of ​​the fan-shaped baffle 13 covering the fan-shaped through slot 15, thereby achieving the purpose of changing the ventilation volume.

[0023] Please see Figure 5 Each group of sector-shaped through slots 15 has 2 to 3 slots. In each group, the sector-shaped through slots 15 are distributed in a circle around the drive shaft 14. The number and position of sector-shaped baffles 13 are matched with the sector-shaped through slots 15. This ensures that the sector-shaped baffles 13, which are adjusted by rotation, will not block the next sector-shaped through slot 15 when they do not block the corresponding sector-shaped through slot 15. This makes the number and position of sector-shaped baffles 13 and sector-shaped through slots 15 more reasonable.

[0024] Please see Figure 2The control components include a dual-output shaft motor 10, a synchronous pulley 11, and a synchronous belt 12. The dual-output shaft motor 10, aligned with the cabinet 4, is fixedly installed on the outside of the machine room 2. The dual-output shaft motor 10 is an existing servo motor with output shafts at both ends and encoders. It can rotate both output shafts to a specified angle simultaneously. The output ends and drive shafts 14 of the dual-output shaft motor 10 are fixedly installed with synchronous pulleys 11. A synchronous belt 12 is sleeved between the two synchronous pulleys 11 located at the same end of the cabinet 4. The machine room 2 and the base 1 have through slots for the synchronous belt 12 to pass through. When the dual-output shaft motor 10 rotates its output end, it can simultaneously rotate the drive shafts 14 aligned vertically with the cabinet 4 after being driven by the synchronous pulleys 11 and the synchronous belt 12.

[0025] In addition, a protective cover 3 is fixedly installed on the outside of the machine room 2. The dual-output shaft motor 10 and the synchronous pulley 11 at the output end are located inside the corresponding protective cover 3, which serves to isolate and protect them and prevent staff from accidentally touching them.

[0026] A rubber frame 16 is fitted at the bottom of the cabinet 4. During installation, the rubber frame 16 is fitted over the outside of the cabinet 4 and kept 10 cm away from the placement surface. This does not affect the movement of the cabinet 4. When in use, the rubber frame 16 is manually pressed down until the bottom of the rubber frame 16 abuts against the upper surface of the base 1, which plays a sealing role. This allows the cold energy delivered by the lower adjustment component to enter the cabinet 4 smoothly through the rubber frame 16, preventing cold energy leakage and ensuring the utilization rate of cold energy.

[0027] Please see Figure 3 The front, back, and bottom sides of the cabinet 4 are provided with an integral U-shaped cavity. A hollow support plate 20 connected to the U-shaped cavity is fixedly installed inside the cabinet 4. The upper surface of the hollow support plate 20 is used to place equipment. The bottom of the cabinet 4 is provided with an air inlet 19 aligned with the lower adjustment component. Ventilation holes 22 are evenly provided on the top of the hollow support plate 20. Air outlets 21 are evenly provided on the side wall of the cabinet 4 near the computer room 2. Air outlets 21 are provided on the top of the hollow support plate 20. A temperature sensor 23 is fixedly installed on the top inner side of the cabinet 4. A cabinet door is hinged on the side of the cabinet 4 away from the air outlet 21. After the cabinet door is closed, each cabinet 4 will form an independent space, and the internal temperature is detected by the temperature sensor 23.

[0028] During operation, the cold air entering from the air inlet 19 is guided by the U-shaped cavity to enter each hollow support plate 20 evenly, and then discharged upward from the ventilation hole 22 to provide targeted cooling for the equipment placed on each layer. After heat exchange, it is discharged from the corresponding air outlet 21.

[0029] Please see Figure 2The conveying channel includes a rectangular channel 5 and a bucket-shaped channel 6 connected together. The bucket-shaped channel 6 is fixedly assembled with the partition 9, and the bucket-shaped channel 6 is aligned with the upper adjustment component. The rectangular channel 5 has a rectangular slot on the side near the cabinet 4 that is aligned with the air outlet 21. After the cabinet 4 is placed, one side of the cabinet 4 abuts against the rectangular channel 5, and each air outlet 21 is aligned with the corresponding rectangular slot. The air discharged from each cabinet 4 can be guided upward through the rectangular channel 5 and the bucket-shaped channel 6. The individual exhaust conveying of each cabinet 4 can avoid mutual interference between exhausts.

[0030] When in use, a separate controller is installed in one of the cabinets 4. The temperature sensor 23, the exhaust fan 7, and the dual-axis motor 10 are electrically connected to this controller. The controller processes the information collected by the temperature sensor 23 and controls the dual-axis motor 10 to work.

[0031] Temperature sensor 23 is a DS18B20 digital temperature sensor, which can directly output digital signals without the need for additional analog-to-digital conversion circuits. Temperature sensor 23 transmits the temperature information collected in cabinet 4 to the controller in the form of digital signals. The controller communicates with the temperature sensor through a specific communication interface (such as a single bus interface).

[0032] The working principle of this embodiment: During operation, the cold air enters the distribution chamber from the air inlet duct 17, then enters the rubber frame 16 through the lower adjustment component, and finally enters the cabinet 4 for distribution and use. After heat exchange with the equipment, the hot air enters the conveying channel from the air outlet 21, then enters the negative pressure chamber through the upper adjustment component, and finally is discharged from the exhaust fan 7.

[0033] During the process, the temperature in each cabinet 4 is collected by the temperature sensor 23. The control component adjusts the adjustment components at the top and bottom of the cabinet 4 respectively, and at the same time changes the air intake and exhaust volume to reasonably allocate the cooling capacity and improve the utilization rate of the cooling capacity.

[0034] 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, 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. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
