[0075] The specific embodiments of the present invention will be described in more detail below with reference to the accompanying drawings, which show representative embodiments of the present invention and are not intended to limit the present invention.

[0076] This utility model provides a data center.

[0077] Please see Figures 1 to 4 The data center 100 includes a enclosure 110, an isolation component 120, and server units 130. The isolation component 120 is disposed inside the enclosure 110, dividing the internal space of the enclosure 110 into a receiving area 121 and a heat dissipation channel 122. Multiple server units 130 are disposed within the receiving area 121. Each server unit 130 includes a cooling device 133 and has a heat dissipation side 131. A hot air channel 123 is formed between the heat dissipation side 131 of any server unit 130 and the inner wall of the enclosure 110, or between the heat dissipation sides 131 of other server units 130. It should be noted that the isolation component 120 has multiple openings 129 connecting the receiving area 121 and the heat dissipation channel 122. Each opening 129 is openable and closable, and the positions of the multiple openings 129 correspond to the multiple hot air channels 123. An exhaust fan 115 is also provided at each opening 129. Furthermore, the data center 100 also includes a control device (not shown) for receiving signals from the cooling equipment 133 to control the opening and closing of the openings 129 and the start and stop of the exhaust fans 115. In the event that the cooling equipment 133 in at least one unit 130 is shut down, the control device controls all openings 129 to open and controls the exhaust fans 115 at the openings 129 corresponding to the hot air passages 123 formed by the unit 130 where the cooling equipment 133 is shut down to draw hot air into the heat dissipation passages 122 and transfer it to other hot air passages 123 through other openings 129.

[0078] According to this solution, in the event of a failure of the cooling equipment 133, the hot air generated by the operation of the equipment in the unit 130 can circulate through the heat dissipation channel 122, avoiding the formation of local high temperature points and improving the reliability of the data center 100.

[0079] Please continue reading. Figures 1 to 3 The plane containing the isolation member 120 is perpendicular to the height direction DH of the container 110. The isolation member 120 is located between the inner top surface of the container 110 and the unit 130. Multiple units 130 are arranged sequentially and spaced apart from each other along a first horizontal direction, and at least one side of each unit 130 is spaced apart from the inner wall of the container 110 along a second horizontal direction perpendicular to the first horizontal direction. Preferably, the container 110 is constructed as a shipping container, with the first horizontal direction being the length direction DL of the container and the second horizontal direction being the width direction DW of the container. Those skilled in the art know that a shipping container generally includes a base frame 111, a top plate 112, end plates 113, and side plates 114. The top plate 112 is located above the base frame 111. The end plates 113 are arranged in pairs, with the two end plates 113 spaced apart along the length direction DL of the container. The side plates 114 are arranged in pairs, with the two side plates 114 spaced apart along the width direction DW of the container. The top plate 112 is located above and connected to the end plate 113 and the side plate 114. The base frame 111 is located below and connected to the end plate 113 and the side plate 114. Figure 2 In the middle, along the width direction DW of the container, the unit 130 abuts against one of the side panels 114 and is spaced apart from the other side panel 114.

[0080] Please continue reading. Figure 2 Along the length direction DL of the container, the leftmost unit 130 is spaced apart from the inner wall of the container 110 to form a hot air passage 123. That is, a hot air passage 123 is formed between the heat dissipation side 131 of any unit 130 and the inner wall of the container 110. Along the length direction DL of the container, the two middle units 130 are spaced apart to form a hot air passage 123. That is, a hot air passage 123 is formed between the heat dissipation side 131 of any unit 130 and the heat dissipation side 131 of the other units 130. Furthermore, the data center 100 also includes a sealing member 127, which is disposed between the heat dissipation side 131 and the inner wall of the container 110. The sealing member 127 is connected to the heat dissipation side 131 and the inner wall of the container 110. Figure 3 It can be seen that the enclosed component 127, the heat dissipation side 131, the inner wall of the box 110 and the isolation component 120 enclose and form a hot air channel 123. Figure 2 In this configuration, at least one enclosure 127 is disposed between the heat dissipation sides 131 of two adjacent units 130, and the enclosure 127 is connected to the two adjacent heat dissipation sides 131. Figure 3 It can be seen that the enclosed component 127, the heat dissipation side 131, the inner wall of the box 110 and the isolation component 120 enclose and form a hot air channel 123.

[0081] Please see now Figures 1 to 3The unit 130 also includes a cooling side 132, which is spaced apart from the heat dissipation side 131 along a first horizontal direction. It can be understood that two adjacent cooling sides 132 along the first horizontal direction, together with the inner wall of the housing 110 and the isolation member 120, form a cold air channel 124. Preferably, the first horizontal direction is configured as the length direction DL of the housing 110.

[0082] Please proceed to Figure 3 and Figure 4 The data center 100 also includes an opening / closing member 128 disposed on the isolation member 120. The opening / closing member 128 is configured to be pivotally connected to the isolation member 120 between an open position and a closed position of the opening 129. It should be noted that the control device is configured to control the opening / closing member 128 to hover at any position between the open and closed positions. The control device is, for example, disposed inside the enclosure 110. In other words, the control device is capable of adjusting the size of the opening 129. Preferably, the opening / closing member 128 is configured as a louver, such as an electric louver. It is understood that when the louver is in the open position, the hot air passage 123 communicates with the heat dissipation passage 122. The exhaust device 115 is preferably configured as an exhaust fan, and the control device is configured to adjust the speed of the exhaust fan.

[0083] Please see now Figures 1 to 3 Preferably, the refrigeration equipment 133 is configured as an air conditioner. Those skilled in the art will know that air conditioners generally consist of an outdoor unit and an indoor unit. The internal space of the housing 110 includes a first accommodating space 125 and a second accommodating space 126. The first accommodating space 125 and the second accommodating space 126 are spaced apart along the length direction DL of the housing 110. The outdoor unit of the air conditioner is disposed in the first accommodating space 125. The second accommodating space 126 is divided by a separating member 120 into an accommodating area 121 and a heat dissipation channel 122 spaced apart along the height direction DH of the housing 110. The indoor unit of the air conditioner and other equipment such as the unit 130 are placed in the accommodating area 121.

[0084] Please see now Figure 2 , Figure 4 and Figure 5 The unit 130 also includes cabinets 134, with at least two cabinets 134. Along a second horizontal direction, at least two cabinets 134 are located on the same side of the refrigeration unit 133. Further, the unit 130 includes a first unit 140 and a second unit 150. The first unit 140 includes the refrigeration unit 133 and at least two first cabinets 141. The second unit 150 includes the refrigeration unit 133, second cabinets 151, and a third cabinet 152.

[0085] Figure 2In this unit, unit 130 includes four first units 140 and one second unit 150. Along the length DL of the housing 110, the four first units 140 are referred to as first unit 140, second unit 140, third unit 140, and fourth unit 140. First unit 140 is spaced from the inner wall of housing 110 to form a hot air passage 123. First unit 140 and first unit 140 are spaced apart to form a cold air passage 124. First unit 140 and first unit 140 are spaced apart to form a hot air passage 123. First unit 140 and first unit 140 are spaced apart to form a cold air passage 124. First unit 140 and second unit 150 are spaced apart to form a hot air passage 123. Furthermore, Figure 2 In this configuration, the first unit 140 includes a cooling unit 133 and two first server racks 141. To simplify the equipment configuration, the second unit 150 and the fourth first unit 140 can share a single cooling unit 133. It should be noted that the server racks 134 are generally used to house power distribution equipment, servers, and network equipment. These devices generate heat during operation, which is dissipated as hot air into the hot air duct 123. For example... Figure 2 The second cabinet 151 is generally constructed as an integrated UPS (Uninterruptible Power Supply) distribution cabinet, and the third cabinet 152 is generally constructed as a battery cabinet.

[0086] Please continue reading. Figure 2 , Figure 4 and Figure 5 The cooling equipment 133 includes an air outlet 135 and a return air outlet 136, with the return air outlet 136 located on the heat dissipation side 131. The server rack 134 includes an air inlet 137 and an air outlet 138. The air inlet 137 connects the air outlet 135 to the interior of the server rack 134, and the air outlet 138 connects the hot air passage 123 to the interior of the server rack 134, allowing hot air generated by the operation of equipment inside the server rack 134 (such as the aforementioned power distribution equipment, servers, and network equipment) to flow back to the return air outlet 136.

[0087] See below Figure 2 and attached Figure 3 Briefly describe the process of hot air formation and elimination.

[0088] When all four cooling units 133 are operating normally, the openings 129 above the three hot air ducts 123 are closed, and the exhaust fans at the openings 129 are also turned off. The hot air generated by the operation of the equipment inside the rack 134 flows through the exhaust vents 138 of the rack 134 into the hot air ducts 123. At this time, the hot air in the hot air ducts 123 is isolated from the heat dissipation ducts 122 and cannot flow into them. In this way, the cooling units 133 can completely draw in the hot air in the hot air ducts 123 through the return air vents 136, cool it internally, and then blow it out. The cooled air then enters the rack 134 through the air inlet vents 137 and is exhausted through the air outlet vents 138. This repeated cooling process cools the air and dissipates heat from the heat-generating equipment inside the rack 134. This improves the cooling efficiency of the cooling units 133, reduces energy consumption, and thus reduces the PUE of the data center, making the data center 100 more green and energy-efficient.

[0089] If one of the refrigeration units 133 needs to be shut down for maintenance or due to a malfunction, the shutdown sequence is as follows: along the length DL of the enclosure 110 from left to right, taking the shutdown of the first refrigeration unit 133 as an example, the shutdown of the other refrigeration units 133 is similar. At this time, the hot air discharged from the heat dissipation side 131 of the first unit 140 in the first hot air duct 123 cannot flow back to the first refrigeration unit 133 for continued cooling. The hot air in the hot air duct 123 accumulates, causing the temperature to rise rapidly and forming a localized hot spot. This affects the heat-generating equipment inside the cabinet 134. When the temperature is too high, it can cause the heat-generating equipment inside the cabinet 134 to shut down, affecting the continuity of operations.

[0090] At this time, the control device receives a shutdown signal from the first refrigeration unit 133 and controls the opening / closing component 128 to pivot to the open position. For example, the opening / closing component 128 is constructed as an electric louver, which pivots to a position perpendicular to the plane of the opening 129, so that the opening 129 is fully open. Simultaneously, the control device controls the exhaust fan 115 at the opening 129 corresponding to the hot air passage 123 formed by the shut-down refrigeration unit 130 to draw hot air to the heat dissipation passage 122 and transfer it to other hot air passages 123 through other openings 129. The hot air can be cooled by the other three refrigeration units 133 and then blown into the cabinet 134. At the same time, the control device can automatically adjust the pivot angle of the opening / closing component 128 according to the return air temperature of the other three refrigeration units 133, and the control device can also adjust the speed and airflow of the exhaust fan according to the return air temperature of the other three refrigeration units 133. This eliminates the problem of heat accumulating inside the hot air duct 123 corresponding to the shutdown cooling equipment 133, ensuring the safe and stable operation of the data center 100, and preventing the equipment inside the rack 134 from crashing due to excessive temperature.

[0091] When the refrigeration equipment 133, which has been shut down for maintenance or due to a malfunction, resumes normal operation, the control device controls the opening and closing component 128 to pivot to the closed position, and at the same time controls the exhaust device 115 to stop operating.

[0092] According to this invention, the data center effectively solves the problems of mixed hot and cold air flow and low cooling efficiency of cooling equipment in data centers. It achieves hot and cold air isolation, improves the cooling efficiency of cooling equipment, and reduces the overall PUE value of the data center. It also solves the problem that when one cooling device shuts down, hot air in the hot air aisle cannot smoothly flow back to the remaining cooling devices for continued cooling, thus resolving the issue of localized high-temperature hotspots in the data center. This ensures that equipment in the server racks will not crash due to excessive temperature, guaranteeing the safe, stable, and continuous operation of the data center. Even when multiple or all cooling devices are shut down, the hot air in the hot air aisle can still flow to at least the interior of the cooling channel, allowing the data center to still have a temporary cooling effect.
