Description

Technical Field

[0001] This application relates to the field of data center cold pool structures, and in particular to a computer room cold pool device, a computer room cooling capacity regulation system, and a data center computer room. Background Technology

[0002] With technological advancements, many data center server rooms now feature enclosed cold aisle configurations, significantly reducing energy consumption by minimizing the area requiring air conditioning and isolating hot and cold airflows. A cold aisle configuration involves placing two rows of servers side-by-side, sealing their air intakes with airtight doors and ceilings, and then directly connecting them to the air conditioning intake. The air conditioning system then delivers cool air directly to the server intakes through an underfloor cold aisle, effectively lowering the equipment's operating temperature.

[0003] Existing cold aisle sealing technology reduces air conditioning energy consumption by reducing the cooling area inside the computer room, but this technology cannot achieve precise air delivery. Utility Model Content

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" 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 direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0041] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0042] In this application, "multiple" means two or more (including two).

[0043] See Figure 1 , Figure 2 , Figure 3 and Figure 5As shown in the figure, this application embodiment provides a computer room cold pool device. The computer room cold pool device is installed below a computer room and includes a cold pool 1 and multiple airflow guiding components 2. The cold pool 1 includes an air inlet 11, and the multiple airflow guiding components 2 are disposed within the cold pool 1, spaced apart. In a first state, an underground cold channel 6 is formed between any adjacent airflow guiding components 2. In a second state, the underground cold channel 6 is formed between any adjacent airflow guiding components 2, and at least one airflow guiding component 2 is partially recessed to form a cold air flow channel 7, which communicates with the underground cold channel 6.

[0044] In some feasible implementations, when the computer room is operating normally, the computer room cold pool device is in its first state, with cold air in the cold pool 1 being transported along the underground cold channel 6. When a local hot spot occurs in the computer room, the computer room cold pool device is switched from the first state to the second state. The flow guiding component 2 below the local hot spot area forms a concave cold air flow guiding channel 7. Since the cold air flow guiding channel 7 is located below the local hot spot area, it guides the transport path of the cold air, delivering the cold air to the local hot spot for precise cooling and effectively improving heat dissipation efficiency. When the local hot spot dissipates, the concave cold air flow guiding channel 7 of the flow guiding component 2 in the local hot spot area can be removed, forming the underground cold channel 6 of the computer room cold pool device in its first state.

[0045] The computer room cold pool device of this application embodiment uses multiple flow guiding components 2 spaced apart to form multiple underground cold channels 6 within the cold pool 1. This guides the path of cold air transmission in the cold pool 1, reduces the cold air circulation area in the underground cold pool 1, and effectively improves heat dissipation efficiency. When a local hot spot occurs in the computer room, a cold air guiding channel 7 is formed by a partial indentation on the flow guiding component 2 below the local hot spot area. The cold air guiding channel 7 can guide the transmission path of cold air in the cold pool 1, accurately delivering cold air to the local hot spot area for efficient cooling and precise air delivery.

[0046] In some feasible ways, such as Figure 1 As shown, the flow guiding assembly 2 includes a baffle structure 3 and multiple support columns 4, which are spaced apart. Each support column 4 is vertically positioned in the cold pool 1, and the baffle structure 3 and the support column 4 are detachably connected.

[0047] In some feasible ways, when installing the flow guide assembly 2, the support column 4 is installed in a predetermined position, and then the baffle structure 3 is connected to the support column 4.

[0048] By setting up the baffle structure 3, the area of ​​cold air flow in the cold pool 1 can be reduced, so that the cold air in the cold pool 1 can be directly transmitted to the underground cold channel 6 and the cold air diversion channel 7, thereby achieving precise air delivery.

[0049] By setting the baffle structure 3 and the support column 4 to be detachably connected, on the one hand, the ease of disassembly and assembly between the baffle structure 3 and the support column 4 is improved, and on the other hand, the baffle structure 3 can be partially disassembled and assembled according to the location of the local hot spot area, thereby facilitating the adjustment of the position of the cold energy guide channel 7.

[0050] In some feasible ways, the material of the support column 4 may include, but is not limited to, aluminum and steel.

[0051] In some feasible ways, such as Figure 2 As shown, in the first state, the baffle structure 3 of the computer room cold pool device includes a first baffle 31 and a second baffle 32, which are arranged at intervals. Both the first baffle 31 and the second baffle 32 are connected to the support column 4.

[0052] In some feasible ways, the first layer baffle 31 includes multiple sub-baffles. The appropriate number of sub-baffles is selected according to the actual length of the cold pool 1. The multiple sub-baffles are connected in sequence by support columns 4 to form the first layer baffle 31.

[0053] The second layer baffle 32 includes multiple sub-baffles. The appropriate number of sub-baffles is selected according to the actual length of the cold pool 1. The multiple sub-baffles are connected in sequence by support columns 4 to form the second layer baffle 32.

[0054] By setting the first baffle 31 and the second baffle 32 at intervals, the cold air circulation area in the cold pool 1 can be reduced, the cold air transmission path can be guided, and the heat dissipation efficiency of the cold pool 1 for the computer room can be improved.

[0055] In some feasible ways, such as Figure 3 and Figure 4 As shown, in the second state, the baffle structure 3 of the computer room cold pool device includes a first baffle 31, a second baffle 32 and a guide plate 33. The first baffle 31 and the second baffle 32 are spaced apart, and the guide plate 33 is spaced between the first baffle 31 and the second baffle 32, forming a concave cold flow channel 7. The guide plate 33 is detachably connected to the support column 4.

[0056] In some feasible implementations, the first layer baffle 31 includes multiple sub-baffles connected by support columns 4 to form the first layer baffle 31. The second layer baffle 32 includes multiple sub-baffles connected by support columns 4 to form the second layer baffle 32.

[0057] In some feasible methods, when a local hot spot occurs in the computer room, the airflow guide component 2 directly below the local hot spot area is modified. Part of the sub-baffle located below the local hot spot area in the first layer baffle 31 is removed, and two airflow guide plates 33 are set between the first layer baffle 31 and the second layer baffle 32. A concave cold airflow guide channel 7 is set between the two airflow guide plates 33. The position of the cold airflow guide channel 7 corresponds to the position of the local hot spot in the computer room. The cold airflow guide channel 7 guides the cold air in the cold pool 1 to be transferred to the local hot spot area, and performs precise heat dissipation on the high-temperature cabinets in the local hot spot area above the cold airflow guide channel 7.

[0058] By setting the guide plate 33 to be detachably connected to the support column 4, the position of the cold air guide channel 7 can be flexibly adjusted according to the different locations of the local hot spots, so as to accurately guide the cold air in the cold pool 1 to the local hot spots, accurately and quickly cool down the high-temperature cabinets in the local hot spots, avoid waste of cold air, and improve the utilization rate of cold air.

[0059] In some examples, such as Figure 4 As shown, the guide plate 33 is an arc-shaped plate.

[0060] In some feasible ways, such as Figure 1 and Figure 2 As shown, the baffle structure 3 includes an arc-shaped baffle 34, which connects the first baffle 31 and the second baffle 32. The arc-shaped baffle 34 is detachably connected to the support column 4 and is located near the air inlet 11.

[0061] In some feasible embodiments, the cold pool 1 includes sidewalls, with the ends of the first baffle 31 and the second baffle 32 away from the air inlet 11 connected to the sidewalls of the cold pool 1, and the ends of the first baffle 31 and the second baffle 32 near the air inlet 11 connected to the arc-shaped baffle 34. The space enclosed by the arc-shaped baffle 34, the first baffle 31, the second baffle 32 and the sidewalls of the cold pool 1 prevents cold air from entering, thereby reducing the area for cold air transmission in the cold pool 1 and improving the utilization rate of the cold energy in the cold pool 1.

[0062] In some feasible implementations, the support column 4 includes a snap-fit ​​component 41, and the baffle structure 3 is snapped and fixed to the snap-fit ​​component 41.

[0063] In some feasible implementations, the first-layer baffle 31 includes multiple sub-baffles. In the first state of the machine room cold pool device, the multiple sub-baffles are sequentially connected to each other via snap-fit ​​components 41 on both sides of the support column 4, thereby completing the assembly of the first-layer baffle 31. The second-layer baffle 32 includes multiple sub-baffles, which are sequentially connected to each other via snap-fit ​​components 41 on both sides of the support column 4, thereby completing the assembly of the second-layer baffle 32. The arc-shaped baffle 34 is connected to the snap-fit ​​component 41 of the support column 4 near the air inlet 11.

[0064] When a local hot spot is generated in the computer room, some of the sub-baffles in the first layer baffle 31 below the local hot spot area are pulled out from the snap-fit ​​component 41, and two guide plates 33 are snapped to different support columns 4. The guide plates 33 are located between the first layer baffle 31 and the second layer baffle 32, forming a temporary cold air guide channel 7 in the local hot spot area to cool down the local hot spot area.

[0065] By setting the snap-fit ​​component 41, the connection between the first layer baffle 31, the second layer baffle 32, the guide plate 33 and the arc-shaped baffle 34 and the support column 4 is made more convenient, effectively improving the efficiency of the connection work.

[0066] In some feasible ways, such as Figure 5 As shown, the snap-fit ​​component 41 includes two clamps 411, which are spaced apart in the horizontal direction to form a snap-fit ​​groove 412. The baffle structure 3 is snap-fitted and fixed to the snap-fit ​​groove 412.

[0067] In some possible implementations, the first-layer baffle 31 includes multiple sub-baffles, which are sequentially inserted into corresponding slots 412 to form the first-layer baffle 31. The second-layer baffle 32 includes multiple sub-baffles, which are sequentially inserted into corresponding slots 412 to form the second-layer baffle 32. The guide plate 33 and the arc-shaped baffle 34 are connected to the first-layer baffle 31 and the second-layer baffle 32 by being inserted into corresponding slots 412.

[0068] In some feasible implementations, during the installation of the computer room cold pool device in its first state, the sub-baffles of the first-layer baffle 31 are first inserted into their corresponding slots 412 in sequence to complete the assembly of the first-layer baffle 31. Then, the sub-baffles of the second-layer baffle 32 are inserted into their corresponding slots 412 in sequence to complete the assembly of the second-layer baffle 32. One end of the arc-shaped baffle 34 is inserted into the slot 412 of the support column 4 connected to the first-layer baffle 31, and the other end of the arc-shaped baffle 34 is inserted into the slot 412 of the support column 4 connected to the second-layer baffle 32, thus completing the connection between the arc-shaped baffle 34 and the first-layer baffle 31 and the second-layer baffle 32.

[0069] In some feasible implementations, when a localized hotspot occurs in the server rack, based on the area of ​​the hotspot, a portion of the sub-baffle located below the localized hotspot in the first-layer baffle 31 is removed from its slot 412. Two guide plates 33 are then taken, with one end of one guide plate 33 inserted into the slot 412 of the support column 4 connected to the first-layer baffle 31, and the other end inserted into the slot 412 of the support column 4 connected to the second-layer baffle 32. The other guide plate 33 undergoes the same connection operation. The two guide plates 33 are positioned opposite each other, and the two guide plates 33 and the second-layer baffle 32 form a locally recessed cold air guiding channel 7 designed for the localized hotspot area.

[0070] By setting the slot 412, the connection between the first layer baffle 31, the second layer baffle 32, the guide plate 33 and the arc-shaped baffle 34 becomes more convenient and faster.

[0071] In some feasible ways, such as Figure 5 As shown, the clamp 411 includes a first plate 4111 and a second plate 4112. The first plate 4111 is connected to the second plate 4112. The first plate 4111 is detachably connected to the support column 4. The second plates 4112 of the two clamps 411, which are spaced apart, are parallel to each other to form a groove 412.

[0072] By setting the first plate 4111 to be detachably connected to the support column 4, the width of the slot 412 can be adjusted by adjusting the position of the first plate 4111 according to the thickness of the first baffle 31, the second baffle 32, the guide plate 33, and the arc baffle 34, thus making the clamp 411 applicable to a wider range.

[0073] In some feasible ways, the included angle between the first plate 4111 and the second plate 4112 is 90 degrees.

[0074] In some feasible ways, the first plate 4111 can be connected to the support column 4 by bolts, but not limited to.

[0075] like Figure 1 As shown, this application embodiment provides a computer room cooling capacity regulation system, including a computer room cold pool device and a refrigeration component 5. The refrigeration component 5 is connected to the computer room cold pool device and is used to provide a cold source to the cold pool 1 through the air inlet 11.

[0076] In some feasible ways, the cooling component 5 continuously supplies cold air to the cold pool 1 through the air inlet 11 of the cold pool 1.

[0077] In some feasible ways, the refrigeration component 5 may include, but is not limited to, an air conditioner.

[0078] like Figure 1 and Figure 6 As shown in the figure, this application embodiment provides a data center server room, including rack rows 8 and a server room cooling system. A rack cold aisle 81 is provided on the side of the rack rows 8. A ventilated floor 9 is provided between the server room cold pool device and the rack rows 8. The ventilated floor 9 is provided with ventilation holes. The underground cold aisle 6 is connected to the rack cold aisle 81 through the ventilation holes.

[0079] In some feasible ways, when cold air is delivered to the underground cold aisle 6, the cold air is delivered to the cabinet cold aisle 81 through the ventilation holes of the ventilated floor 9.

[0080] In some feasible ways, when the cold air is delivered to the cold air diversion channel 7, the cold air is delivered to the localized heat-generating area of ​​the cabinet through the ventilation holes of the ventilation floor 9.
