Detailed Description
In the prior art, in order to cool air in the cabinet, a back panel air conditioner is arranged on a back door of the cabinet. In this solution, the cooling area of the backplane air conditioner is limited by the size of the rear door of the cabinet. Generally, the cooling area of the back panel air conditioner is smaller than the size of the rear door of the cabinet, because the rear door of the cabinet includes not only the back panel air conditioner but also a door frame for fixing the back panel air conditioner and a duct structure for connecting the back panel air conditioner. In order to improve the cooling effect of the back plate air conditioner, the density of the internal structure of the back plate air conditioner needs to be increased, and the increase of the density of the internal structure of the back plate air conditioner can increase air resistance, so that air cannot be smoothly blown out of a cabinet to generate an internal vortex phenomenon, and the cooling effect of the air conditioner is further reduced. Therefore, the existing air conditioning scheme has the technical problems of poor flexibility, poor cooling effect and the like.
In order to solve or partially solve the technical problem, embodiments of the present application provide a new air conditioning scheme. In the scheme, the air inlet surface of the air-conditioning wall is opposite to the air outlet surface of the cabinet row and is arranged at intervals, and a sealed hot channel is formed between the air-conditioning wall and the cabinet row. The cabinet row discharges hot air into the hot channel through the air outlet surface of the cabinet row, the hot air in the hot channel enters the air conditioning wall through the air inlet surface of the air conditioning wall, the air conditioning wall cools the hot air entering the air conditioning wall, and then the cold air is discharged through the air outlet surface of the air conditioning wall. That is to say, the technical scheme that this application embodiment provided decouples air conditioner and rack, and like this, the refrigeration area of air conditioner is not restricted by the rack back door size, but can come the nimble design according to actual need. Therefore, by adopting the technical scheme provided by the embodiment of the application, the refrigerating effect can be increased by increasing the refrigerating area of the air-conditioning wall. In addition, in the technical scheme provided by the embodiment of the application, hot air in the whole machine room is concentrated in the sealed hot channel between the air conditioning wall and the cabinet row, namely, the temperature of the area except the hot channel in the machine room is lower, and the hot air is in a cold air environment, so that the hot air is very friendly to workers in the machine room.
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below according to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that, the descriptions of "first", "second", etc. in this document are used for distinguishing different messages, devices, modules, etc., and do not represent a sequential order, nor limit the types of "first" and "second" to be different.
Fig. 1 is a block diagram illustrating a cooling apparatus of a data center room according to an embodiment of the present disclosure; fig. 2 shows a schematic plan view of a cooling device provided in an embodiment of the present application. As shown in fig. 1 and 2, the data center room includes a cabinet column 1; the cabinet column 1 includes a plurality of cabinets 11 arranged in sequence. As shown in fig. 1 and 2, the cooling apparatus includes: the air conditioning wall 2 comprises an air inlet surface 201 and an air outlet surface 202 which are oppositely arranged; the air inlet surface 201 of the air conditioning wall 2 is opposite to the air outlet surface 101 of the cabinet row 1 and is arranged at intervals; a hot channel 100 is formed between an air outlet surface 101 of the cabinet row 1 and an air inlet surface 201 of the air conditioning wall 2; the air-conditioning wall 2 is configured to cool air entering from an air inlet surface 201 of the air-conditioning wall 2, and discharge the cooled air through an air outlet surface 202 of the air-conditioning wall 2.
The cabinet array 1 includes an air inlet surface 102 and an air outlet surface 101 which are oppositely disposed. The cabinet 11 includes an air inlet surface and an air outlet surface which are arranged oppositely. The air outlet surfaces of the plurality of cabinets 11 which are sequentially arranged are positioned on the same side so as to form an air outlet surface 101 of the cabinet row 1; the air inlet surfaces of the multiple cabinets 11 arranged in sequence are located on the same side to form the air inlet surface 102 of the cabinet row 1.
In one example, any adjacent two of the plurality of cabinets 11 arranged in sequence may be connected to each other.
The air conditioning wall 2 may include one air conditioning unit or a plurality of air conditioning units arranged in sequence.
In one example, the air conditioning wall 2 includes an air conditioning unit 21. In order to satisfy the cooling requirement of multiple cabinets, the area of the air conditioning unit 21 is designed to be large. In this case, the air inlet surface of the air conditioning unit 21 constitutes the air inlet surface of the air conditioning wall 2, and the air outlet surface of the air conditioning unit 21 constitutes the air outlet surface of the air conditioning wall 2.
In another example, the air conditioning wall 2 includes a plurality of air conditioning units 21 arranged in sequence. The air conditioning unit 21 comprises an air inlet surface and an air outlet surface which are oppositely arranged; the air inlet surfaces of the air conditioning units 21 are positioned on the same side to form an air inlet surface 201 of the air conditioning wall 2; the air outlet surfaces of the air conditioning units 21 are located on the same side to form the air outlet surface 202 of the air conditioning wall 2.
In this embodiment, the air-conditioning wall 2 is composed of a plurality of air-conditioning units 21, so that when one of the air-conditioning units fails, the other air-conditioning units 21 can continue to operate to cool down the hot air in the heat channel 100, that is, all the cabinets can be cooled down. In the existing back panel air conditioning scheme, once a back panel air conditioner on the back door of a certain cabinet fails, the back panel air conditioner on the back door of other cabinets cannot be utilized to cool the cabinet. Therefore, compared with the prior art, the scheme has higher reliability.
The distance between the air inlet surface 201 of the air conditioning wall 2 and the air outlet surface 101 of the cabinet row 1 may be set according to actual needs, which is not specifically limited in the embodiment of the present application. In an example, the distance may be greater than or equal to 1 meter and less than or equal to 1.2 meters.
In an embodiment, as shown in fig. 2, the air inlet surface 201 of the air conditioning wall 2 and the air outlet surface 101 of the cabinet row 1 may be disposed in parallel and opposite to each other.
In an example, the air conditioning wall 2 and the cabinet row 1 may be connected by a connector to form a heat channel 100 between the air outlet surface 101 of the cabinet row 1 and the air inlet surface 201 of the air conditioning wall 2. In particular, the connecting member may be a structural member (i.e. a mechanical structural member), and the structural member is a member capable of bearing a certain load. In other words, as shown in fig. 2, the air conditioning wall 2 is connected to the cabinet row 1 through a structural member 3, so as to form a heat channel 100 between an air outlet surface 101 of the cabinet row 1 and an air inlet surface 201 of the air conditioning wall 2.
The thermal channel may in particular be a closed thermal channel. The air (hot air) in the hot air duct 100 flows from the air outlet surface 101 of the cabinet row 1 to the air inlet surface 201 of the air conditioning wall 2.
The air conditioning wall 2 may be configured to suck air from the heat channel 100 through the air inlet surface 201 of the air conditioning wall 2, cool the sucked air, and discharge the cooled air through the air outlet surface 202 of the air conditioning wall 2. In an example, the cooled air discharged from the air outlet surface 202 of the air conditioning wall 2 can enter the air inlet surface of the cabinet row 1 through circulation inside the machine room to cool the electronic equipment in the cabinet 11.
In the technical scheme that this application embodiment provided, the air inlet face with the air-conditioning wall is relative and the interval sets up with the air-out face that the rack was listed as, forms heat channel between air-conditioning wall and rack are listed as. The cabinet row discharges hot air into the hot channel through the air outlet surface of the cabinet row, the hot air in the hot channel enters the air conditioning wall through the air inlet surface of the air conditioning wall, the air conditioning wall cools the hot air entering the air conditioning wall, and then the cold air is discharged through the air outlet surface of the air conditioning wall. That is to say, the technical scheme that this application embodiment provided decouples air conditioner and rack, and like this, the refrigeration area of air conditioner will not receive the restriction of rack back door size, but can come the nimble design according to actual need. It can be seen that the technical scheme flexibility that this application embodiment provided is high, and adopt the technical scheme that this application embodiment provided, the accessible increases the refrigeration area of air conditioner wall and improves refrigeration effect.
In addition, in the technical scheme provided by the embodiment of the application, hot air is concentrated in the hot channel between the air conditioning wall and the cabinet row, that is to say, the temperature of the area outside the hot channel in the machine room is lower, and the machine room is quite friendly to workers in the machine room because the machine room is in a cold air environment.
In one example, the air inlet surface of the air conditioning unit is larger in area than the air outlet surface of the cabinet. Because air conditioning unit and rack have carried out the decoupling zero in this application embodiment, consequently, the area of the air inlet face of air conditioning unit can set up the area that is greater than the air-out face of rack, like this, helps improving the cooling effect.
For example, one air conditioning unit may correspond to two or three cabinets, that is, the area of the air inlet surface of the air conditioning unit may be equal to or greater than the sum of the areas of the air outlet surfaces of the two or three cabinets.
Under the condition that the total area of the air-conditioning wall is fixed, the larger the area of the air inlet surface of the air-conditioning unit is, for the whole air-conditioning wall, the occupied area ratio of a frame assembly and the like used for fixing the air-conditioning unit in the air-conditioning wall is relatively reduced, and the effective refrigerating area of the air-conditioning wall is increased.
In one example, as shown in fig. 3, the plurality of air conditioning units 21 includes a first air conditioning unit 211 and a second air conditioning unit 212 disposed adjacent to each other; the first air conditioning unit 211 comprises a first heat exchanger; the second air conditioning unit 212 includes a second heat exchanger; the data center computer room further comprises: the system comprises a main liquid supply pipeline 400, a main liquid return pipeline 500, a first liquid supply branch pipeline 401 connected to a first position A of the main liquid supply pipeline 400, a second liquid supply branch pipeline 402 connected to a second position C of the main liquid supply pipeline 400, a first liquid return branch pipeline 501 connected to a third position B of the main liquid return pipeline 500 and a second liquid return branch pipeline 502 connected to a fourth position D of the main liquid return pipeline 500; a liquid inlet of the first heat exchanger is connected to the first liquid supply branch pipeline 401; a liquid outlet of the first heat exchanger is connected to the first liquid return branch pipeline 501; the liquid inlet of the second heat exchanger is connected with the second liquid supply branch pipeline 402; the liquid outlet of the second heat exchanger is connected to the second liquid return branch pipe 502.
In one example, the first air conditioning unit and the second air conditioning unit may be two air conditioning units that are disposed adjacent to each other in any of a plurality of air conditioning units.
Each of the above heat exchangers may include, but is not limited to: finned tube heat exchanger, gilled tube heat exchanger, tube-and-strip heat exchanger, microchannel heat exchanger.
Specifically, the first liquid supply branch pipe 401 and the first liquid return branch pipe 501 may be connected to the liquid supply main pipe 400 and the liquid return main pipe 500 through valves, respectively. Thus, when a problem occurs in one of the first liquid supply branch pipe 401 and the first liquid return branch pipe 501, the valve can be closed, and the maintenance of the branch pipe with the problem in the first liquid supply branch pipe 401 and the first liquid return branch pipe 501 is facilitated.
The second liquid supply branch pipe 402 and the second liquid return branch pipe 502 may be connected to the liquid supply main pipe 400 and the liquid return main pipe 500 through valves, respectively. Thus, when a problem occurs in one of the second liquid supply branch pipe 402 and the second liquid return branch pipe 502, the valve may be closed, and the problem branch pipe in the second liquid supply branch pipe 402 and the second liquid return branch pipe 502 may be repaired.
The liquid inlet of the first heat exchanger can be connected with the first liquid supply branch pipeline 401 through a valve; a liquid outlet of the first heat exchanger can be connected to the first liquid return branch pipeline 501 through a valve; the liquid inlet of the second heat exchanger can be connected with the second liquid supply branch pipeline 402 through a valve; the liquid outlet of the second heat exchanger can be connected to the second liquid return branch pipe 502 through a valve. Therefore, when a certain air conditioning unit needs to be maintained, the valve corresponding to the heat exchanger of the air conditioning unit can be closed.
As shown in fig. 3, the air conditioning wall 2 further includes a fifth air conditioning unit 213; the first air conditioning unit 211, the second air conditioning unit 212, and the fifth air conditioning unit 213 are sequentially arranged. The fifth air conditioning unit 213 comprises a fifth heat exchanger, and a liquid inlet of the fifth heat exchanger is connected to the first liquid supply branch pipeline 401; a liquid outlet of the fifth heat exchanger is connected to the first liquid return branch pipe 501. Specifically, a liquid inlet of the fifth heat exchanger may be connected to the first liquid supply branch pipeline 401 through a valve; a liquid outlet of the fifth heat exchanger may be connected to the first liquid return branch pipe 501 through a valve.
In this embodiment, two air conditioning units disposed adjacently are connected to the main pipe through different branch pipes, respectively. When a certain branch pipeline fails, although the air conditioning unit connected to the branch pipeline cannot normally work, the air conditioning unit adjacent to the air conditioning unit can continuously work due to the fact that the air conditioning unit is connected to the other branch pipeline, and local high temperature caused by the fact that the certain air conditioning unit cannot normally work is avoided. And when the air conditioning units are multiple, two adjacent air conditioning units are respectively connected with the main pipeline through two different branch pipelines, and when a certain branch pipeline breaks down, the multiple air conditioning units connected to the other branch pipeline can uniformly cool the hot air in the hot channel, so that local high temperature in the channel can be effectively avoided. Exemplarily, as shown in fig. 3, liquid inlets of the heat exchangers of the air conditioning units numbered 1, 3, 5, and 7 are respectively connected to a first liquid supply branch pipeline 401; liquid outlets of heat exchangers of air conditioning units numbered 1, 3, 5 and 7 are respectively connected with a first liquid return branch pipeline 501; liquid inlets of the heat exchangers of the air conditioning units numbered 2, 4, 6 and 8 are respectively connected with a second liquid supply branch pipeline 402; liquid outlets of the heat exchangers of the air conditioning units numbered 2, 4, 6, 8 are respectively connected with the second liquid return branch pipe 502. When one of the first liquid supply branch pipeline 401 and the first liquid return branch pipeline 501 has a problem, the air conditioning units numbered 2, 4, 6 and 8 can continue to uniformly cool the hot channel. When one of the second liquid supply branch pipe 402 and the second liquid return branch pipe 502 has a problem, the air conditioning units numbered 1, 3, 5, and 7 can continue to uniformly cool the hot channel.
In one example, as shown in FIG. 3, a first valve 403 is disposed on the main liquid supply conduit 400 between the first position A and the second position C; a second valve 503 is disposed on the liquid return main pipe 500 between the third position B and the fourth position D.
In practical applications, when a problem occurs in one of the second liquid supply branch pipe 402 and the second liquid return branch pipe 502, the first valve 403 and the second valve 503 may be closed, so as to facilitate maintenance of the defective branch pipe in the second liquid supply branch pipe 402 and the second liquid return branch pipe 502.
The number of the first valve 403 and the second valve 503 may be two. And the system reliability is improved through a redundancy design.
Optionally, as shown in fig. 4, the cooling device may further include: a first electric control cabinet 600; the first electric control cabinet 600 comprises a first power supply unit 601 and a second power supply unit 602; the first power supply unit 601 and the second power supply unit 602 are used for converting alternating current into direct current; the input end of the first power supply unit 601 is connected with the commercial power output end; the input terminal of the second power supply unit 602 is connected to the output terminal of the uninterruptible power supply (i.e., U power in fig. 4); the output end of the first power supply unit 601 and the output end of the second power supply unit 602 are connected with the power supply end of the first electric control cabinet 600; and a third air conditioning unit in the plurality of air conditioning units 21 is connected with the power supply end of the first electric control cabinet.
In a specific structure, the plurality of air conditioning units 21 are all connected to the power supply terminal of the first electric control cabinet 600, that is, the first electric control cabinet 600 supplies power to the plurality of air conditioning units 21.
Generally, two paths of alternating currents cannot be directly combined due to the problems of phase difference and the like. In order to supply both the commercial power and the ups, the first power unit 601 and the second power unit 602 convert ac power into dc power, so that the two dc powers can be combined and the combined dc power can supply power to the air conditioning unit. That is, in this embodiment, the first power supply unit 601 and the second power supply unit 602 can simultaneously supply the direct current to the power supply terminal of the first electric control cabinet 600. When the branch where the commercial power and the first power supply unit 601 are located is powered off, the branch where the uninterruptible power supply and the second power supply unit 602 are located can continuously provide direct current to the power supply end of the first electric control cabinet 600; when the uninterruptible power supply and the branch where the second power supply unit 602 is located are powered off, the commercial power and the branch where the first power supply unit 601 is located will continue to provide direct current to the power supply terminal of the first electric control cabinet 600. That is, when any branch is powered off, the air conditioning unit does not flash, that is, the air conditioning unit does not have the phenomenon of short power failure caused by power supply switching in the prior art.
Optionally, as shown in fig. 4, the first electronic control cabinet 600 further includes: a first master controller 603; the first main controller 603 is connected with a power supply end of the first electric control cabinet 600; the third air conditioning unit is connected to the first main controller 603; the first master controller 603 is connected to an external control center system (i.e., BA in fig. 4).
The first main controller 603 may be configured to control an outlet air temperature of the third air conditioning unit, a flow rate of a refrigerant in a heat exchanger thereof, and the like; and the third air conditioning unit is also used for uploading the air inlet temperature and the air outlet temperature of the third air conditioning unit to an external control center system so as to facilitate the global management and control of the external control center system.
In a specific structure, the air conditioning units 21 are all connected to the first main controller 603, that is, the first main controller 603 controls the air conditioning units 21 and uploads information of the air conditioning units to the external control center system.
