The multiple second temperature sensors are distributed in the hot zone, and each magnetic attraction device is connected to a corresponding magnetic attraction point.

[0005] In one embodiment of this application, the data center server room further includes: multiple A-line power distribution cabinets and multiple B-line power distribution cabinets, each of the cabinets being electrically connected to the corresponding A-line power distribution cabinet and the corresponding B-line power distribution cabinet.

[0007] In one embodiment of this application, the data center computer room further includes: two air conditioning rooms, which are arranged opposite each other on both sides of the hot zone. The lower air supply vent of each air conditioning room is connected to the plurality of cold zones, and the upper air return vent of each air conditioning room is connected to the hot zone. Each air conditioning room is equipped with a plurality of air conditioners.

[0008] In one embodiment of this application, the data center server room further includes: a static pressure box, which is located below the plurality of cold zones, the hot zones and the server racks. Each of the air-conditioning rooms is connected to the plurality of cold zones through the static pressure box. The static pressure box is a diffuse static pressure box, and the height of the static pressure box is 500mm to 1000mm.

[0009] In one embodiment of this application, the air outlet of the air-conditioning room is aligned and connected with the corresponding cold zone along the extension direction of the corresponding cold zone, wherein the hot zone is a diffuse hot zone.

[0024] To more clearly illustrate the technical solutions of the embodiments of this application, the accompanying drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are merely some examples or embodiments of this application. For those skilled in the art, these drawings can be applied to other similar scenarios without creative effort. Unless obvious from the context or otherwise specified, the same reference numerals in the drawings represent the same structures or operations.

[0025] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not specifically singular and may include plural forms. Generally speaking, the terms "comprising" and "including" only indicate the inclusion of explicitly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements.

[0026] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0027] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0028] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.

Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0029] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. In addition, although the terminology used in this application is selected from commonly known and used terms, some terms mentioned in this application's specification may have been chosen by the applicant according to his or her judgment, and their detailed meanings are explained in the relevant sections of this description. Moreover, this application should be understood not only through the actual terms used, but also through the meaning implied by each term.

[0030] The data center computer room of this application will be described next through examples.

[0031] refer to Figure 1 As shown, the data center server room includes: multiple cold zones 110, multiple hot zones 120, multiple skylights 130, and a skylight control system 140. The skylight control system 140 includes multiple first temperature sensors 141, multiple second temperature sensors 142, a control unit 143, multiple relays 144, multiple contactors 145, and multiple magnetic devices 146.

[0032] To elaborate, in Figure 1 In this embodiment, the data center includes four cold zones 110, each extending along a first direction D1. Server racks 150 are arranged opposite each other on both sides of each cold zone 110, and each rack 150 may include multiple servers arranged sequentially adjacent to each other along the first direction D1. In one embodiment, the multiple cold zones 110 are divided into at least two rows, with at least two rows of cold zones 110 arranged adjacent to each other along the first direction D1. Each row of cold zones includes multiple cold zones 110 arranged along a second direction D2. It should be noted that the number and arrangement of the cold zones 110 are not limited to... Figure 1 As shown, the settings can be adjusted according to actual conditions. For ease of understanding, the following text uses four cold zones 110 as an example to illustrate the technical solution of this application.

[0033] Continue to refer to Figure 1 As shown, hot zone 120 surrounds four cold zones 110. For ease of understanding, in... Figure 1 The boundary of hot zone 120 is indicated by dashed lines. The shape of the boundary of hot zone 120 is not limited to... Figure 1 A rectangle can be used, but it can also be other shapes.

[0034] Each cooling zone 110 has six skylights 130 arranged along the first direction D1 above it, and each skylight 130 has a magnetic attraction point 131. During normal operation of the data center server room, the skylights 130 are closed to prevent the cold air within the cooling zone 110 from escaping. The number of skylights 130 is not limited to this. Figure 1 The six options can be configured according to your needs.

[0035] The sunroof control system 140 includes multiple first temperature sensors 141, multiple second temperature sensors 142, a control unit 143, multiple relays 144, multiple contactors 145, and multiple magnetic suction devices 146. The multiple first temperature sensors 141 are distributed within corresponding cold zones 110, with at least two first temperature sensors 141 located in each cold zone 110. Each first temperature sensor 141 can sense the temperature of its respective cold zone 110. The multiple second temperature sensors 142 are distributed within hot zones 120. For example, along the second direction D2, two second temperature sensors 142 are respectively located on both sides of each cold zone 110. Each second temperature sensor 142 can sense the temperature of its respective hot zone 120.

[0036] The control unit 143 is connected 144 to multiple first temperature sensors 141, multiple second temperature sensors 142, and multiple relays. Each contactor 145 is connected to a corresponding relay 144 and a corresponding magnetic attraction device 146. Each magnetic attraction device 146 is energized or demagnetized and disconnected from a corresponding magnetic attraction point 131. The connection between the magnetic attraction device 146 and the corresponding magnetic attraction point 131 is not the focus of this application and will not be described in detail. The number of relays 144 is the same as the number of contactors 145 and the number of magnetic attraction devices 146. The control unit 143 collects temperature measurements from the first temperature sensors 141 and the second temperature sensors 142, and can perform comprehensive calculations based on the temperature measurements to send signals (e.g., output pulse signals) to one or more relays 144. The relays 144 then send signals to the contactors 145. The contactors 145 control the magnetic attraction devices 146 to demagnetize the magnetic attraction point 131 according to the signals. After demagnetization, the sunroof 130 opens under the action of gravity. This application controls the opening of multiple skylights 130 in a data center server room through a single control unit 143, which helps reduce costs. Furthermore, the skylight control system of this application does not require changes to the original structure of the data center server room and can be deployed on the existing architecture of the data center server room.

[0037] In one embodiment, when the temperatures sensed by the two first temperature sensors 141 located in the same cold zone 110 are both below a predetermined low-temperature threshold, the control unit 143 sends a signal to the relay 144 to open the sunroof 130. The relay 144 transmits the signal to the contactor 145, which controls the magnetic attraction device 146 to disconnect from the magnetic attraction point 131, and the sunroof 130 opens under the action of gravity. In this way, the cold air in the cold zone 110 can be dissipated through the sunroof, thereby raising the temperature in the cold zone 110 to a suitable temperature.

[0038] In one embodiment, the control unit 143 can also control the audible and visual alarm device to issue an audible and visual alarm. A predetermined low threshold can be set as needed; there can be one or more predetermined low thresholds. When there are multiple predetermined low thresholds, different levels of predetermined low thresholds can be set, and different levels of predetermined low thresholds correspond to different audible and visual alarm formats. The data center server room may include a management page for setting the predetermined low thresholds.

[0039] In one embodiment, when the data center server room is operating normally, the temperature sensed by the first temperature sensor 141 should be lower than the temperature sensed by the second temperature sensor 142. If the temperature sensed by the first temperature sensor 141 should be higher than the temperature sensed by the second temperature sensor 142, the control unit 143 can control the audible and visual alarm device to issue an audible and visual alarm to remind staff to adjust the temperature of the cold and hot zones.

[0040] In one embodiment, after the temperature anomaly has persisted for a certain period of time, the control unit 143 begins to process the temperature anomaly event, thus avoiding false alarms.

[0041] In one embodiment, the control unit 143 includes a programmable logic controller (PLC) 143a and a data acquisition device 143b. The PLC 143a is connected to the data acquisition device 143b and is also connected to a relay 144. The data acquisition device 143b is connected to a first temperature sensor 141 and a second temperature sensor 142. Figure 1 In order to simplify the schematic diagram, only the connection lines between the acquisition device 143b and part of the second temperature sensor 142 are shown, and the connection lines between the acquisition device 143b and the remaining second temperature sensor 142 and the first temperature sensor 141 are not shown.

[0042] In one embodiment, the relay is a two-contact relay, with the two contacts including a main contact and an auxiliary contact. The main contact is used to control the opening of the sunroof, and the auxiliary contact is used to control the audible and visual alarm device. The relay may include a self-holding circuit to ensure that it remains in the open state after power failure until manually reset.

[0043] refer to Figure 1As shown, the data center also includes multiple A-path power distribution cabinets 160 and multiple B-path power distribution cabinets 170. Each cabinet 150 is electrically connected to one A-path power distribution cabinet 160 and one B-path power distribution cabinet 170, and is also electrically connected to both A-path and B-path power distribution cabinets 160 and 170. This allows power to be supplied to cabinet 150 from the other power source if one mains power source fails. The data center may also include an uninterruptible power supply (UPS), allowing power to continue supplying power to the data center even if both mains power sources fail. The power distribution cabinets corresponding to the adjacent cold zone 110 in the first direction D1 are staggered to avoid electromagnetic interference between the power distribution cabinets.

[0044] In one embodiment, the data center server room further includes two air-conditioning rooms 180, which are arranged opposite each other on both sides of the hot zone 120 in the first direction D1, and each air-conditioning room 180 is equipped with a plurality of air conditioners. Figure 1 The air supply vents of each air conditioning room 180 are connected to multiple cold zones 110, and the return air vents of each air conditioning room 180 are connected to hot zones 120. The data center server room may include a plenum (not shown), located below multiple cold zones 110, hot zones 120, and server racks 150. Each air conditioning room 180 is connected to multiple cold zones 110 via the plenum. The air supply vents of the air conditioning room 180 are aligned and connected to the corresponding cold zone 110 along the extension direction (i.e., the first direction D1), allowing cold air from the air conditioning room 180 to flow directly into the cold zones 110, thus shortening the cold air flow path. Hot zones can be diffused hot zones. The plenum can be a diffused plenum, and its height can range from 500mm to 1000mm, for example, 500mm, 600mm, 700mm, 800mm, 900mm, or 1000mm. A height less than 500mm is not conducive to the circulation of cold air, while a height greater than 1000mm not only increases costs but also dilutes the cold air. Having air conditioning rooms 180 on both sides of the hot zone 120 facilitates balanced management of the plenum's cooling capacity.

[0045] In one embodiment, a partition wall (not shown) is provided between each air-conditioned room 180 and the hot zone 120, separating the air-conditioned room 180 from the hot zone 120. The lower part of the partition wall is fireproof gypsum board, and the upper part of the partition wall is louvers, including louvers in the upper return air vent. Cool air in the air-conditioned room 180 can flow from the lower air supply vent to the cold zone 110, and then flow back to the air-conditioned room 180 through the louvers.

[0046] In one embodiment, the base plate of the cold zone 110 is a metal ventilation grille, and the base plate of the hot zone 120 is an anti-static floor. The floor legs are connected to the building's equipotential grounding point via copper wires.

[0047] In one embodiment, the data center server room also includes power cable trays and low-voltage cable trays, with the power cable trays located below the base plate and the low-voltage cable trays located above the server racks.
