Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of heat dissipation, and particularly relates to a computer room cold aisle and a computer room cold aisle heat dissipation system. BACKGROUND

[0002] In order to improve the heat dissipation effect of the computer room, the newly-built computer room usually assembles the cabinets into a closed cold aisle, and transports cold air into the closed cold aisle through a special air conditioner, so as to limit the cold air in a specific aisle, reduce the mixing of the cold air and the hot air, enable the cold air to be more effectively sucked into the cabinet, thereby improving the efficiency of the refrigeration system and reducing the air conditioner energy consumption.

[0003] However, the cabinets of the existing old computer room usually adopt an open structure, and the cabinets are indirectly cooled and dissipated through the cabinet air conditioner after the whole room is cooled by the air conditioner, which increases the air conditioner energy consumption, and the temperature of the cold air blown out by the air conditioner is increased after being mixed with the hot air in the computer room, which further leads to the poor heat dissipation effect of the in-use cabinet. SUMMARY

[0004] The utility model solves the above-mentioned problems existing in the prior art, and provides a computer room cold aisle and a computer room cold aisle heat dissipation system, which can improve the heat dissipation effect of the in-use cabinet in the existing computer room and reduce the air conditioner energy consumption by forming a closed heat dissipation aisle.

[0005] In a first aspect, the utility model provides a computer room cold aisle, which comprises a cabinet group, an air inlet sealing plate and a channel sealing assembly. The cabinet group is located in a communication computer room and comprises two parallel cabinet groups. Each cabinet group is formed by sequentially arranging a plurality of sub-cabinets, and the sub-cabinets comprise an in-use cabinet and an idle cabinet. A heat dissipation aisle is formed between the two cabinet groups, and the air inlets of all the sub-cabinets face the heat dissipation aisle. The air inlet sealing plate is arranged at the air inlet of the idle cabinet and is used for sealing the air inlet of the idle cabinet in the cabinet group. The channel sealing assembly is arranged at the top and both ends of the heat dissipation aisle of the cabinet group, and the channel sealing assembly is connected with the two cabinet groups of the cabinet group and is used for sealing the top and both ends of the heat dissipation aisle of the cabinet group to seal the heat dissipation aisle. The heat dissipation aisle is used for receiving the externally transported cold air. The cold air entering the heat dissipation aisle enters the in-use cabinet through the air inlet of the in-use cabinet and is discharged to the outside of the computer room cold aisle through the air outlet of the in-use cabinet, so as to realize the heat dissipation of the in-use cabinet.

[0006] In some embodiments, each of the channel closing assemblies comprises a top skylight and a movable door. The top skylight is arranged at the top of the cooling channel and is in closed connection with the top of the cabinet group, for closing the top of the cooling channel. The movable door is two in number, and the two movable doors are movably arranged at the two ends of the cooling channel. Each of the movable doors is in closed connection with two sub-cabinets at the end of the cabinet group, for closing the two ends of the cooling channel. Each of the movable doors can be opened or closed.

[0007] In some embodiments, each column of cabinets in the cabinet group is provided with a connecting strip at the top, and the two connecting strips are parallel to each other. The top skylight comprises a partition plate which is detachably clamped between the two connecting strips, for closing the top of the cooling channel.

[0008] In some embodiments, horizontal clamping grooves are formed on the opposite sides of the two connecting strips. The partition plate is slidably arranged in the horizontal clamping grooves, so as to realize the detachable connection between the partition plate and the connecting strips.

[0009] In some embodiments, the partition plate is a transparent plate.

[0010] In some embodiments, the movable door is a transparent glass door.

[0011] In some embodiments, the computer room cooling channel further comprises a blind plate. The blind plate is arranged between two adjacent sub-cabinets in a column of cabinets, and the height of the blind plate is the same as the height of the sub-cabinets, for closing the gap between the two adjacent sub-cabinets.

[0012] In some embodiments, the number of cabinet groups is multiple, and accordingly, the number of air inlet closing plates and channel closing assemblies is also multiple.

[0013] Thus, the machine room cold channel provided by the embodiment of the utility model, through making the in-use cabinet and the idle cabinet form two rows of cabinets in turn, a cooling channel can be formed between the two rows of cabinets. By setting the channel closing assembly on the top and both ends of the cooling channel of the cabinet group, the channel closing assembly is connected with the two rows of cabinets of the cabinet group, the top and both ends of the cooling channel of the cabinet group can be closed, so that the cooling channel is closed. By making the air inlets of all the sub-cabinets face the cooling channel and setting the air inlet closing plate at the air inlet of the idle cabinet, the air inlet of the idle cabinet can be closed, the cold air in the cooling channel can be prevented from flowing out of the air inlet of the idle cabinet, the cold air in the cooling channel can enter the in-use cabinet through the air inlet of the in-use cabinet, and the in-use cabinet is cooled, so that the cooling effect of the in-use cabinet is improved, and the utilization rate of the cold air is improved. Compared with the old machine room in which the air conditioner is directly used to cool the whole room to cool and radiate heat for the sub-cabinet, the machine room cold channel in the embodiment only needs to cool the small space in the cooling channel by the air conditioner to cool and radiate heat for the in-use cabinet, so that the energy consumption of the air conditioner can be reduced, and the mixing and temperature rise of the cold air blown out by the air conditioner and the hot air in the room can be avoided to affect the cooling and heat radiation effect of the in-use cabinet. The machine room cold channel of the embodiment of the utility model directly uses the existing in-use cabinet and idle cabinet in the machine room to form the main frame of the machine room cold channel, and does not need to additionally purchase an overall three-dimensional frame, so that the cost is saved, and the existing idle cabinet is prevented from occupying the space in the machine room to affect the air flow near the in-use cabinet, so that the cooling of the in-use cabinet is not affected.

[0014] In the second aspect, the embodiment of the utility model further provides a machine room cold channel cooling system, the machine room cold channel cooling system includes the machine room cold channel and the cooling air conditioner in the first aspect. The air outlet of the cooling air conditioner is communicated with the cooling channel of the machine room cold channel, and is used for conveying cold air into the cooling channel of the machine room cold channel to cool the in-use cabinet in the machine room cold channel by the cold air.

[0015] In some embodiments, the machine room cold channel cooling system further includes a temperature and humidity sensor and a controller. The temperature and humidity sensor is arranged in the cooling channel, and is used for detecting the temperature and humidity data of the air in the cooling channel and transmitting to the controller. The controller is electrically connected with the temperature and humidity sensor and the cooling air conditioner respectively, and is used for adjusting the temperature and humidity of the cold air conveyed into the cooling channel by the cooling air conditioner according to the received temperature and humidity data of the air in the cooling channel, so that the temperature and humidity of the air in the cooling channel is maintained within a preset range.

[0016] The machine room cold channel cooling system provided by the embodiment of the utility model has the same beneficial effects as the above machine room cold channel, which will not be repeated here. BRIEF DESCRIPTION OF DRAWINGS

[0020] In order to enable those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] Embodiment 1

[0022] As shown in the figure, the present application provides a cold aisle of a machine room, which is applied to a communication machine room and can be used to transform in-use cabinets and idle cabinets in an old machine room to improve the heat dissipation effect of the in-use cabinets in the old machine room. Figure 1 As shown in the figure, the cold aisle of the machine room includes a cabinet group, an air inlet blocking plate and a passage blocking assembly 5. As shown in the figure, the cabinet group is located in the communication machine room and includes two parallel rows of cabinets, each row of cabinets is formed by a plurality of sub-cabinets arranged in sequence, and each sub-cabinet includes an in-use cabinet 1 and an idle cabinet 2. A heat dissipation passage is formed between the two rows of cabinets, and the air inlets of all the sub-cabinets are all directed to the heat dissipation passage.

[0023] Figure 1 Figure 2

[0024] Exemplarily, the sub-cabinets can be communication cabinets, power supply cabinets, etc. The sub-cabinets are placed on the floor in the machine room.

[0025] Each sub-cabinet has an air inlet and an air outlet. Air enters the sub-cabinet from the air inlet of the sub-cabinet and flows out of the sub-cabinet from the air outlet, so as to take away the heat of the sub-cabinet and realize heat dissipation of the sub-cabinet.

[0026] Exemplarily, the in-use cabinet 1 represents that the equipment in the sub-cabinet is in a working or powered-on state; and the idle cabinet 2 represents that the equipment in the sub-cabinet is in a powered-off state, or the sub-cabinet is not installed with equipment and is an empty cabinet.

[0027] Exemplarily, the number of in-use cabinets 1 can be one or more, and the number of idle cabinets 2 can be one or more. The number of in-use cabinets 1 and idle cabinets 2 can be determined according to the actual use of the sub-cabinets.

[0028] ​​​In a row of cabinets, the used cabinet 1 and the idle cabinet 2 can be arranged arbitrarily. For example, the used cabinet 1 can be adjacent to the used cabinet 1, or the used cabinet 1 can be adjacent to the idle cabinet 2, or the idle cabinet 2 can be adjacent to the idle cabinet 2.

[0029] exist Figure 2 The total number of sub-racks is twenty, of which ten are in use (rack 1) and ten are idle (rack 2), and the in-use racks 1 and idle racks 2 are arranged alternately.

[0030] The arrangement of the two rows of cabinets in the cabinet group can be as follows: each row of cabinets in the cabinet group is formed by arranging in-use cabinet 1 and idle cabinet 2; or, only one row of cabinets is formed by arranging in-use cabinet 1 and idle cabinet 2, and the other row of cabinets is formed entirely by arranging in-use cabinet 1; or, only one row of cabinets is formed by arranging in-use cabinet 1 and idle cabinet 2, and the other row of cabinets is formed entirely by arranging idle cabinet 2.

[0031] It should be noted that in each row of cabinets, any two adjacent sub-cabinets are in contact with each other to reduce the gap between adjacent cabinets and improve the sealing of the heat dissipation channel formed between the two rows of cabinets.

[0032] Combination Figure 1 and Figure 2 An air inlet sealing plate is installed at the air inlet of the vacant rack 2 to block the air inlet of the vacant rack 2 in the rack group. Aisle sealing components 5 are installed at the top and both ends of the heat dissipation aisle of the rack group, and are connected to two rows of racks in the rack group. These components are used to block the top and both ends of the heat dissipation aisle, thus sealing it off. The heat dissipation aisle receives externally supplied cold air. The cold air entering the heat dissipation aisle enters the interior of the rack 1 through its air inlet and is discharged to the outside of the cold aisle of the server room from its air outlet, thus achieving heat dissipation for the rack 1.

[0033] For example, the air inlet sealing plate can be a commonly used board material that can serve a sealing function, such as wood or plastic board. In other examples, plastic film can also be used to seal the air inlet of the unused cabinet 2.

[0034] By blocking the air inlet of the vacant rack 2, the airflow inside the rack can be prevented. Figure 1 As shown, this can further improve the sealing of both sides of the heat dissipation channel.

[0035] For example, the channel closure component 5 can be a commonly used board or film that can play a sealing role, such as wood, plastic board, plastic film, etc.

[0036] Combination Figure 1 and Figure 2By setting the channel closing assembly 5, two rows of cabinets can be surrounded by the closed cooling channel between the two rows of cabinets.

[0037] For example, the externally delivered cold air can be the cold air blown by the air outlet of the air conditioner.

[0038] For example, the pipeline structure can be arranged under the floor of the machine room, one end of the pipeline structure is communicated with the air outlet of the air conditioner, and the other end is communicated with the cooling channel through the opening of the floor.

[0039] As shown in Figure 1 The air inlets of all sub-cabinets are directed towards the cooling channel, and the air inlets of the idle cabinets 2 are blocked, so that the cold air entering the cooling channel can only enter the in-use cabinet 1 through the air inlet of the in-use cabinet 1 to cool the in-use cabinet 1, reducing the loss of cold air caused by the outflow of cold air through the idle cabinet 2 to the outside, and improving the utilization rate of cold air; compared with the old machine room directly using the air conditioner to cool the entire room to realize the cooling and heat dissipation of the sub-cabinet, the cooling channel in the embodiment only needs to cool the smaller space in the cooling channel through the air conditioner to realize the cooling and heat dissipation of the in-use cabinet 1, so that the energy consumption of the air conditioner can be reduced, and the mixing of the cold air blown by the air conditioner and the hot air in the room to cause the temperature rise can be avoided, thereby affecting the cooling and heat dissipation effect of the in-use cabinet 1.

[0040] In addition, the closed cooling channel in the newly built machine room is assembled by a whole three-dimensional frame, which is very inconvenient during transportation and assembly, and the whole three-dimensional frame needs to be purchased, which has high cost.

[0041] The cooling channel of the machine room directly utilizes the existing in-use cabinet 1 and idle cabinet 2 in the machine room to form the cooling channel of the machine room, without the need for additional purchase of a whole three-dimensional frame, thereby saving costs and avoiding the existing idle cabinet 2 occupying the space in the machine room to affect the air flow near the in-use cabinet 1, thereby avoiding the occurrence of the heat dissipation of the in-use cabinet 1. Therefore, the cooling channel of the machine room in the embodiment is particularly suitable for the modification of the existing in-use cabinet 1 and idle cabinet 2 in the old machine room.

[0042] Thus, the machine room cold channel provided by the embodiment of the utility model, through making the in-use cabinet 1 and the idle cabinet 2 are arranged in two rows to form two rows of cabinets, a heat dissipation channel can be formed between the two rows of cabinets. By setting the channel closing assembly 5 at the top and both ends of the heat dissipation channel of the cabinet group, the channel closing assembly 5 is connected with the two rows of cabinets of the cabinet group, the top and both ends of the heat dissipation channel of the cabinet group can be closed to close the heat dissipation channel; by making the air inlets of all the sub-cabinets face the heat dissipation channel and setting the air inlet closing plate at the air inlet of the idle cabinet 2, the air inlet of the idle cabinet 2 can be closed, the cold air in the heat dissipation channel can be prevented from flowing out of the air inlet of the idle cabinet 2, the cold air in the heat dissipation channel can enter the in-use cabinet 1 through the air inlet of the in-use cabinet 1 to dissipate heat for the in-use cabinet 1, the heat dissipation effect of the in-use cabinet 1 is improved, and the utilization rate of the cold air is improved. Compared with the old machine room in which the air conditioner is directly used to cool the whole room to achieve the heat dissipation and cooling of the sub-cabinet, the machine room cold channel in the embodiment only needs to cool the small space in the heat dissipation channel by the air conditioner to achieve the heat dissipation and cooling of the in-use cabinet 1, so that the energy consumption of the air conditioner can be reduced, and the mixing and temperature rise of the cold air blown out by the air conditioner and the hot air in the room can be avoided to affect the heat dissipation and cooling effect of the in-use cabinet 1. The machine room cold channel of the embodiment of the utility model directly uses the existing in-use cabinet 1 and idle cabinet 2 in the machine room to form the main frame of the machine room cold channel, without the need of additionally purchasing an overall three-dimensional frame, so that the cost is saved, and the existing idle cabinet 2 is prevented from occupying the space in the machine room to affect the air flow near the in-use cabinet 1, so that the heat dissipation of the in-use cabinet 1 is not affected.

[0043] In some embodiments, as shown in Figure 1 Each channel closing assembly 5 includes a top skylight 3 and a movable door 4. The top skylight 3 is arranged at the top of the heat dissipation channel and is closedly connected with the top of the cabinet group, and is used for closing the top of the heat dissipation channel. The number of movable doors 4 is two, and the two movable doors 4 are movably arranged at the two ends of the heat dissipation channel. Each movable door 4 is closedly connected with two sub-cabinets at the end of the cabinet group, and is used for closing the two ends of the heat dissipation channel. Each movable door 4 can be opened or closed.

[0044] For example, the material of the top skylight 3 can be transparent or opaque plate material, such as wood board, metal plate, plastic plate, etc., which can achieve the effect of closing the top of the heat dissipation channel.

[0045] For example, the top skylight 3 can be fixedly connected with the top of the cabinet group, for example, the top skylight 3 is welded and fixed on the top of the cabinet group; or the top skylight 3 can be connected with the top of the cabinet group through bolts and other fasteners.

[0046] For example, the movable door 4 can be hinged on two sub-cabinets at the ends of the cabinet group, and the middle part of the movable door 4 can be opened; or the movable door 4 is a sliding door, and the guide rail of the movable door 4 is fixed on the two sub-cabinets at the ends of the cabinet group.

[0047] By arranging the top skylight 3 and the movable door 4, when a fire accident occurs in the cold aisle of the machine room, smoke can be discharged by removing the top skylight 3 and opening the movable door 4. The movable door 4 also facilitates the entry of staff into the heat dissipation channel to maintain the in-use cabinet 1.

[0048] In some embodiments, a connecting strip is arranged at the top of each row of cabinets in the cabinet group, and the two connecting strips are parallel to each other. The top skylight 3 comprises a partition plate which is detachably clamped between the two connecting strips and used to block the top of the heat dissipation channel.

[0049] For example, the material of the connecting strip can be metal, such as steel or aluminum, to increase the strength and service life of the connecting strip.

[0050] For example, each connecting strip is fixed to the top of the corresponding row of cabinets by a bolt or the like.

[0051] For example, the gap between the two connecting strips is matched with the width of the partition plate. After the partition plate is placed between the two connecting strips, it can be clamped with the two connecting strips, thereby improving the clamping firmness and sealing between the partition plate and the two connecting strips, and achieving the blocking of the top of the heat dissipation channel.

[0052] For example, the number of partition plates can be one or more, and the number of partition plates is arranged according to the length of the cabinet group and the length of the partition plate.

[0053] For example, if the length of the cabinet group is 10 meters and the length of the partition plate is also 10 meters, only one partition plate needs to be arranged; if the length of the cabinet group is 10 meters and the length of the partition plate is 2 meters, five partition plates need to be arranged.

[0054] Through the above arrangement, the assembly and disassembly of the top skylight 3 are facilitated.

[0055] In some embodiments, horizontal clamping grooves are arranged on the opposite sides of the two connecting strips. The partition plate is slidingly arranged in the horizontal clamping grooves to achieve detachable connection of the partition plate and the connecting strips.

[0056] For example, the connecting strip is an aluminum strip, so that the horizontal clamping grooves can be easily machined in the aluminum strip.

[0057] The gap distance of the horizontal clamping groove is slightly larger than the thickness of the partition plate, so that the partition plate can slide in the horizontal clamping groove.

[0058] When the isolation plate needs to be installed or dismounted, the isolation plate can be slid into or out of the connecting strip along the slot of the horizontal slot.

[0059] Through the above setting, the isolation plate can be conveniently installed and dismounted on the connecting strip.

[0060] In some embodiments, the isolation plate is a transparent plate.

[0061] For example, the isolation plate is a transparent acrylic plate. The transparent acrylic plate has the advantages of good light transmission, light weight, easy processing and low cost.

[0062] By setting the transparent isolation plate, external light can be shot into the heat dissipation channel, improving the lighting effect in the heat dissipation channel. It is also convenient to observe the situation in the heat dissipation channel through the isolation plate, and convenient to install a camera outside the cold aisle of the machine room to monitor the picture in the heat dissipation channel.

[0063] In some embodiments, the movable door 4 is a transparent glass door.

[0064] Similarly, external light can be shot into the heat dissipation channel through the transparent glass door, improving the lighting effect in the heat dissipation channel. It is also convenient to observe the situation in the heat dissipation channel through the transparent glass door, and convenient to install a camera outside the cold aisle of the machine room to monitor the picture in the heat dissipation channel.

[0065] In some embodiments, the cold aisle of the machine room further comprises a blind plate. The blind plate is arranged between two adjacent sub-cabinets in a row of cabinets, and the height of the blind plate is the same as the height of the sub-cabinets, for plugging the gap between the two adjacent sub-cabinets.

[0066] For example, the blind plate can be a metal plate, a plastic plate, etc.

[0067] For example, the two ends of the blind plate are connected with the two adjacent sub-cabinets in the cabinet respectively, so as to maintain the sealing between the blind plate and the two sub-cabinets.

[0068] As shown in Figure 2 The lengths of the two rows of cabinets in the cabinet group need to be equal, so that the side of the heat dissipation channel formed by the two rows of cabinets does not form a gap.

[0069] When the widths of the sub-cabinets in the two rows of cabinets are inconsistent, or the number of the sub-cabinets in the two rows of cabinets is inconsistent, it may cause the lengths of the two rows of cabinets in the cabinet group to be inconsistent. At this time, a blind plate with a proper width (the width is equal to the length difference of the two rows of cabinets) can be arranged in the shorter one of the two rows of cabinets, so that the lengths of the two rows of cabinets are finally equal, avoiding the formation of a gap in the side of the heat dissipation channel formed by the two rows of cabinets.

[0070] In some embodiments, the number of the cabinet groups is multiple, and accordingly, the air inlet plugging plate and the channel sealing assembly 5 are also multiple.

[0071] Exemplarily, the number of the air inlet sealing plates and the passage closing assemblies 5 is the same as the number of the cabinet groups.

[0072] It can be understood that when the number of the sub-cabinets included in the two rows of cabinets in one cabinet group is large, the volume of the heat dissipation passage formed between the two rows of cabinets is large, and in the case that the flow of the cold air delivered to the heat dissipation passage is constant, the air exchange efficiency of the air in the heat dissipation passage will be reduced.

[0073] Exemplarily, when the communication machine room is large and the number of the sub-cabinets that can be arranged in the communication machine room is large, by arranging multiple cabinet groups, the number of the sub-cabinets in each cabinet group can be reduced, which is beneficial to reduce the volume of the heat dissipation passage formed between the two rows of cabinets in each cabinet group, improve the air exchange efficiency of the cold air in the heat dissipation passage of each cabinet group, and make the temperature of the cold air in the heat dissipation passage closer to the temperature of the air outlet of the air conditioner, i.e., the temperature is lower, which is beneficial to maintain the low temperature of the cold air in the heat dissipation passage and keep the normal heat dissipation effect of the cold air in the heat dissipation passage on the in-use cabinet 1.

[0074] Through the above arrangement, more sub-cabinets in the communication machine room can be arranged in the machine room cold passage, and the heat dissipation effect of the air conditioner on more in-use cabinets 1 can be improved.

[0075] Embodiment 2:

[0076] The utility model embodiment further provides a machine room cold passage heat dissipation system applied to a communication machine room, the machine room cold passage heat dissipation system includes the machine room cold passage and the heat dissipation air conditioner in embodiment 1. The air outlet of the heat dissipation air conditioner is communicated with the heat dissipation passage of the machine room cold passage, and is used to deliver cold air to the heat dissipation passage of the machine room cold passage to cool the in-use cabinet 1 in the machine room cold passage by the cold air.

[0077] Exemplarily, the heat dissipation air conditioner can be a common cabinet air conditioner or a special machine room air conditioner.

[0078] Exemplarily, the air outlet of the heat dissipation air conditioner is located at the bottom end of the heat dissipation air conditioner, a wind guide passage is arranged under the floor of the machine room, one end of the wind guide passage is communicated with the air outlet of the heat dissipation air conditioner, and the other end of the wind guide passage is communicated with the heat dissipation passage in the machine room cold passage, so that the cold air blown out by the heat dissipation air conditioner can be directly delivered to the heat dissipation passage in the machine room cold passage to cool the in-use cabinet 1 in the machine room cold passage.

[0079] Through the above arrangement, the in-use cabinet 1 in the machine room can be cooled, thereby improving the stability of the in-use cabinet 1 during operation. Moreover, because the cold air blown by the heat dissipation air conditioner is directly delivered into the heat dissipation channel in the cold aisle of the machine room, the cold air blown by the heat dissipation air conditioner can be prevented from being mixed with the hot air in the machine room to increase the temperature and reduce the heat dissipation effect of the heat dissipation air conditioner on the in-use cabinet 1, so that the cold air blown by the heat dissipation air conditioner is more used for heat dissipation of the in-use cabinet 1, thereby improving the utilization rate of the cold air blown by the heat dissipation air conditioner and reducing the total energy consumption of the heat dissipation air conditioner.

[0080] In some embodiments, the machine room cold aisle heat dissipation system further comprises a temperature and humidity sensor and a controller. The temperature and humidity sensor is arranged in the heat dissipation channel, and is configured to detect the temperature and humidity data of the air in the heat dissipation channel and transmit the data to the controller. The controller is electrically connected with the temperature and humidity sensor and the heat dissipation air conditioner, respectively, and is configured to adjust the temperature and humidity of the cold air delivered by the heat dissipation air conditioner into the heat dissipation channel according to the received temperature and humidity data of the air in the heat dissipation channel, so that the temperature and humidity of the air in the heat dissipation channel is maintained within a preset range.

[0081] For example, the temperature and humidity sensor is arranged at a top position in the heat dissipation channel. The controller is a general programmable logic controller, for example, a programmable logic controller produced by Siemens with a model number of S7-200.

[0082] The controller can send different control instructions to the heat dissipation air conditioner according to the received temperature and humidity data of the air in the heat dissipation channel, so as to adjust the working state of the heat dissipation channel (for example, to reduce the temperature of the cold air blown by the heat dissipation air conditioner, to reduce the humidity of the cold air blown by the heat dissipation air conditioner, etc.).

[0083] For example, the preset range of the temperature and humidity of the air in the heat dissipation channel can be set according to the actual situation, so as to ensure that the temperature and humidity of the air in the heat dissipation channel can meet the heat dissipation effect on the in-use cabinet 1 in the cold aisle of the machine room within the preset range.

[0084] It should be noted that the humidity in the present embodiment is relative humidity, which is the percentage of the actual water vapor density in a unit volume of air to the saturated water vapor density at the same temperature.

[0085] For example, the preset range of the temperature and humidity of the air in the heat dissipation channel can be: the temperature range is 10-20℃, and the humidity range is 40%-60%. The above preset range of temperature and humidity can be pre-stored in the controller.

[0086] For example, when the temperature value received by the controller is higher than 20℃, the controller sends a first control instruction to the cooling air conditioner to control the cooling air conditioner to further reduce the temperature of the cold air blown out of the air outlet of the cooling air conditioner, increase the air volume of the cooling air conditioner, thereby delivering more cold air with lower temperature into the cooling channel, and reducing the temperature of the air in the cooling channel to the preset range, so as to improve the cooling effect on the in-use cabinet 1 in the cooling channel of the computer room.

[0087] Alternatively, when the temperature value received by the controller is lower than 10℃, the controller sends a second control instruction to the cooling air conditioner to control the cooling air conditioner to increase the temperature of the cold air blown out of the air outlet of the cooling air conditioner, reduce the air volume of the cooling air conditioner, thereby delivering less cold air with higher temperature into the cooling channel, and increasing the temperature of the air in the cooling channel to the preset range, so as to reduce the refrigeration power and energy consumption of the cooling air conditioner.

[0088] Alternatively, when the humidity value received by the controller is higher than 60%, the controller sends a third control instruction to the cooling air conditioner to control the cooling air conditioner to reduce the humidity of the cold air blown out of the air outlet of the cooling air conditioner, thereby delivering cold air with lower humidity into the cooling channel, and reducing the humidity of the air in the cooling channel to the preset range, so as to reduce the risk of corrosion and short circuit of the in-use cabinet 1.

[0089] Alternatively, when the humidity value received by the controller is lower than 40%, the controller sends a fourth control instruction to the cooling air conditioner to control the cooling air conditioner to increase the humidity of the cold air blown out of the air outlet of the cooling air conditioner, thereby delivering cold air with higher humidity into the cooling channel, and increasing the humidity of the air in the cooling channel to the preset range, so as to reduce the possibility of static electricity in the in-use cabinet 1.

[0090] Through the above setting, the temperature and humidity of the air in the cooling channel can be monitored in real time, the temperature and humidity of the air in the cooling channel can be automatically controlled, the safety of the cooling system of the cooling channel of the computer room can be improved, and the energy consumption of the cooling air conditioner can be optimized.

[0091] It can be understood that the above embodiments are only exemplary embodiments adopted for illustrating the principles of the present application, and the present application is not limited thereto. Those skilled in the art can make various modifications and improvements without departing from the spirit and essence of the present application, and these modifications and improvements are also regarded as the protection scope of the present application.
