Description

Technical Field

[0001] This invention relates to the field of underwater data equipment technology, and more specifically, to a seabed data center. Background Technology

[0002] In current technologies, major emerging industries such as artificial intelligence and the industrial internet all require data centers as industrial support. The construction of a large number of data centers will inevitably occupy a lot of land space. Human activities, temperature and humidity fluctuations will also interfere with the operation of servers, thereby affecting network speed and smoothness. In addition, servers generate a lot of heat during operation, which generally requires artificial cooling through fluorine cooling systems. This not only increases energy consumption but also increases carbon emissions, which is not conducive to sustainable development, wastes resources, and pollutes the environment. Summary of the Invention

[0003] The main objective of this invention is to provide an underwater data center to solve the problem of excessive energy consumption caused by cooling data centers in the prior art.

[0004] To achieve the above objectives, the present invention provides an underwater data center for placement on the seabed near coastal cities to improve network speed and smoothness through short-distance transmission. The underwater data center includes a shell and a return air duct. The shell has an IT equipment area and an auxiliary function area. The IT equipment area has a server room module, and the auxiliary function area has a cooling module. The air inlet of the return air duct is connected to the air outlet of the server room module, and the air outlet of the return air duct is connected to the air inlet of the server room module. The cooling module is disposed within the return air duct. The cooling module has a first heat exchange section, which has a flow cavity and a seawater inlet and a seawater outlet connected to the flow cavity to introduce flowing seawater into the flow cavity and exchange heat with the air in the return air duct.

[0005] Furthermore, in the direction from the air outlet to the air inlet of the computer room module, the return air duct includes a first air duct section and a second air duct section that are connected, and a mixing air valve is provided at the connection between the first air duct section and the second air duct section, and the first heat exchange unit is located in the second air duct section.

[0006] Furthermore, the first heat exchange section has multiple ventilation chambers and multiple flow chambers, with at least one flow chamber between two adjacent ventilation chambers, and the air inlet and outlet of the ventilation chamber are connected to the return air duct.

[0007] Furthermore, the ventilation direction of the ventilation cavity is set at an angle to the flow direction of the flow cavity.

[0008] Furthermore, the cooling module also includes a first temperature and humidity sensor, which is located at the air outlet of the first heat exchange section to detect the temperature and humidity at the air outlet of the first heat exchange section.

[0009] Furthermore, the refrigeration module also includes a filter assembly disposed at the air inlet and / or air outlet of the ventilation cavity to filter the air flowing through the ventilation cavity; and / or, the filter assembly disposed at the seawater inlet and / or seawater outlet of the flow cavity to filter the seawater flowing through the flow cavity.

[0010] Furthermore, the filtration assembly includes a first roller, a second roller, and a filter screen, wherein the axes of the first roller and the second roller are arranged parallel to each other; one end of the filter screen is wound around the first roller, and the other end of the filter screen is wound around the second roller; the first roller is used to roll up the portion of the filter screen that has completed the filtration operation, and the second roller is used to release the portion of the filter screen that has not yet been filtered; wherein the filter screen located between the first roller and the second roller is used to filter the air flowing through the ventilation cavity; or, the filter screen located between the first roller and the second roller is used to filter the seawater flowing through the flow cavity.

[0011] Furthermore, multiple guide plates are provided on the first cavity wall of the flow passage, and each guide plate can rotate synchronously to adjust the flow direction.

[0012] Furthermore, the refrigeration module also includes a cleaning component, which is disposed on the second cavity wall of the flow cavity. The second cavity wall is disposed opposite to the first cavity wall. The cleaning component has at least two cleaning ends, which are respectively disposed toward the first cavity wall and the second cavity wall, for cleaning the first cavity wall and the second cavity wall respectively.

[0013] Furthermore, the cleaning assembly includes a guide bracket, a first brush structure, and a second brush structure. The guide bracket is connected to the wall of the second cavity and extends along the extension direction of the flow cavity. The first brush structure is movably mounted on the guide bracket and can move along the extension direction of the guide bracket. The brushes of the first brush structure are positioned near the wall of the second cavity for cleaning the wall of the second cavity. The second brush structure is connected to the first brush structure so that the second brush structure moves with the first brush structure. The brushes of the second brush structure are positioned near the wall of the first cavity for cleaning the wall of the first cavity.

[0014] Furthermore, the second brush structure has a clearance space for avoiding the guide plate. When the cleaning assembly performs cleaning operations, the guide plate rotates to a state where it is 90° to the wall of the first cavity and extends into the clearance space.

[0015] Furthermore, in the direction from the air outlet of the first air duct section to the air inlet of the computer room module, the second air duct section has a first heat exchange section, a second heat exchange section, a third heat exchange section and an air supply box in sequence. At least a part of the first heat exchange section and the second heat exchange section are connected to the first air duct section. The first heat exchange unit is located in the first heat exchange section. A mixing air valve is provided at the connection between the second heat exchange section and the first air duct section.

[0016] Furthermore, the refrigeration module also includes a second heat exchange section, a part of which is located within the second heat exchange section, and another part of which is located outside the shell and submerged in seawater.

[0019] Furthermore, the third heat exchange section includes multiple fan assemblies, which are arranged in an array within the third heat exchange section and are separated from each other by baffles.

[0020] Furthermore, the cooling module also includes a second temperature and humidity sensor, which is located at the air outlet of the third heat exchange section to detect the temperature and humidity at the air outlet of the third heat exchange section.

[0021] By applying the technical solution of this invention, an underwater data center is placed on the seabed near coastal cities to improve network speed and smoothness through short-distance transmission. Because there is no human activity on the seabed, the temperature and humidity are relatively stable, creating a stable and controllable environment inside the data center, suitable for server operation, extending equipment lifespan, and reducing maintenance frequency. The hot air generated by the server room module of the underwater data center is cooled by a cooling module in the return air duct. The cooling module has a first heat exchange section with a flow cavity and a seawater inlet and outlet connected to the flow cavity. This allows flowing seawater to be introduced into the flow cavity and exchanged with the hot air in the return air duct, utilizing cool seawater for natural cooling. This significantly reduces carbon emissions from artificial cooling using air conditioning, lowers energy resource costs, promotes sustainable development, saves land resources, and protects the environment.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0034] To address the issue of excessive energy consumption associated with cooling data centers in existing technologies, this invention provides an underwater data center.

[0035] like Figures 1 to 6As shown, an underwater data center is designed for placement on the seabed near a coastal city to improve network speed and smoothness through short-distance transmission. The underwater data center includes a shell 10 and a return air duct 20. The shell 10 has an IT equipment area and an auxiliary function area. The IT equipment area has a server room module 11, and the auxiliary function area has a cooling module 12. The air inlet of the return air duct 20 is connected to the air outlet of the server room module 11, and the air outlet of the return air duct 20 is connected to the air inlet of the server room module 11. The cooling module 12 is disposed within the return air duct 20. The cooling module 12 has a first heat exchange section 121, which has a flow cavity 1211 and a seawater inlet and a seawater outlet connected to the flow cavity 1211 to introduce flowing seawater into the flow cavity 1211 and exchange heat with the air in the return air duct 20.

[0036] By placing underwater data centers on the seabed near coastal cities, network speed and smoothness can be improved through short-distance transmission. Because there is little human activity on the seabed, and the temperature and humidity are relatively stable, the internal environment of the data center is relatively stable and controllable, making it more suitable for server operation, extending equipment lifespan, and reducing maintenance frequency. The hot air generated by the server room module 11 of the underwater data center is cooled by the cooling module 12 in the return air duct 20. The cooling module 12 has a first heat exchange section 121, which includes a flow cavity 1211 and a seawater inlet and outlet connected to the flow cavity 1211. This allows flowing seawater to be introduced into the flow cavity 1211 and exchanged with the hot air in the return air duct 20, utilizing cool seawater for natural cooling. This significantly reduces carbon emissions from artificial cooling using air conditioning, lowers energy resource costs, promotes sustainable development, saves land resources, and protects the environment.

[0037] It should be noted that, in this application, the auxiliary functional area also includes a power distribution module 13, a battery module 14, and a fire protection module 15. The power distribution module 13 contains electrical equipment and cables such as the main input line, circuit breakers, relays, and branch cables of various sub-components. The battery module 14 can be either lead-acid or lithium batteries to provide backup power for the data center for a certain period of time, ensuring temporary backup power in the event of a power outage. The fire protection module 15 mainly includes heptafluoropropane gas extinguishing equipment and corresponding exhaust fans after gas extinguishing. In addition, the computer room module 11 mainly consists of computing and communication equipment such as servers and switches for data computing, storage, and signal transmission. The computer room module 11 also includes other auxiliary equipment such as dehumidifiers, fresh air units, and integrated monitoring units to maintain the safe, stable, and reliable operation of the computer room.

[0038] It should be noted that, in this application, the IT equipment area also includes a double sliding door 111, a fixed and tilting skylight 112, and other accessories, such as lighting distribution boxes, lamps, and passageway seals. The double sliding door 111 is located on both sides of the computer room module 11, providing access for staff to enter the computer room module 11. The fixed and tilting skylight 112 is located above the computer room module 11 and is opened in the event of a fire.

[0039] like Figure 1 As shown, in the direction from the air outlet to the air inlet of the computer room module 11, the return air duct 20 includes a first air duct section 21 and a second air duct section 22 that are connected. A mixing air valve 23 is provided at the connection between the first air duct section 21 and the second air duct section 22. The first heat exchange unit 121 is located in the second air duct section 22.

[0040] like Figure 1 and Figure 2 As shown, the first heat exchange unit 121 has multiple ventilation chambers 1212 and multiple flow chambers 1211. At least one flow chamber 1211 is located between any two adjacent ventilation chambers 1212. The air inlet and outlet of each ventilation chamber 1212 are connected to the return air duct 20. Thus, by alternating the arrangement of the ventilation chambers 1212 and the flow chambers 1211, it is ensured that the hot air in each ventilation chamber 1212 can be cooled by seawater in the adjacent flow chamber 1211.

[0041] It should be noted that in this application, the first heat exchange section 121 is formed by welding multiple heat exchange plates with ribs. The front and rear ends of the first and second heat exchange plates are welded together, while the upper and lower ends are not welded. Due to the presence of the ribs, the two heat exchange plates are not tightly fitted together, thus forming the first cavity region, i.e., the ventilation cavity 1212, to allow the return airflow to fill this region. The upper and lower ends of the second and third heat exchange plates are welded together, while the front and rear ends are not welded. Again, due to the presence of the ribs, the two heat exchange plates are not tightly fitted together, thus forming the second cavity region, i.e., the flow cavity 1211, to allow the water to fill this region. The third and fourth heat exchange plates are joined in the same way as the first and second heat exchange plates, forming the third cavity region, i.e., the ventilation cavity 1212. This process is repeated to form n cavity regions. The ventilation cavities 1212 and flow cavities 1211 are arranged alternately. The return air and water only exchange heat, not mass, thus achieving water-cooled natural heat exchange.

[0042] It should be noted that in this application, the outer surface of the heat exchange plate is coated with an anti-rust coating to ensure that it will not rust during underwater application.

[0043] like Figure 1 and Figure 2As shown, the ventilation direction of the ventilation cavity 1212 is set at an angle to the flow direction of the flow cavity 1211. This ensures better heat exchange between the hot air in the ventilation cavity 1212 and the seawater in the flow cavity 1211.

[0044] like Figure 2 As shown, the cooling module 12 also includes a first temperature and humidity sensor 122, which is located at the air outlet of the first heat exchange section 121 to detect the temperature and humidity at the air outlet of the first heat exchange section 121. Thus, the first temperature and humidity sensor 122 can detect whether the air temperature and humidity T&H1 after natural heat exchange has reached the set temperature and humidity, and based on this judgment condition, cause the cooling module 12 to enter different control modes.

[0045] like Figure 2 As shown, the refrigeration module 12 also includes a filter assembly 123, which is disposed at the air inlet and / or air outlet of the ventilation cavity 1212 to filter the air flowing through the ventilation cavity 1212; and / or, the filter assembly 123 is disposed at the seawater inlet and / or seawater outlet of the flow cavity 1211 to filter the seawater flowing through the flow cavity 1211. In this way, the filter assembly 123 can prevent blockage of the ventilation cavity 1212 and the flow cavity 1211.

[0046] like Figure 3 As shown, the filter assembly 123 includes a first roller 1231, a second roller 1232, and a filter screen 1233. The axis of the first roller 1231 and the axis of the second roller 1232 are arranged parallel to each other. One end of the filter screen 1233 is wound around the first roller 1231, and the other end of the filter screen 1233 is wound around the second roller 1232. The first roller 1231 is used to roll up the part of the filter screen 1233 that has completed the filtration operation, and the second roller 1232 is used to release the part of the filter screen 1233 that has not yet been filtered. The filter screen 1233 located between the first roller 1231 and the second roller 1232 is used to filter the air flowing through the ventilation cavity 1212; or, the filter screen 1233 located between the first roller 1231 and the second roller 1232 is used to filter the seawater flowing through the flow cavity 1211. In this way, when the filter screen 1233 is contaminated by impurities in the seawater, the first roller 1231 and the second roller 1232 can be driven to rotate in the same direction, thereby taking away the part of the filter screen 1233 that has completed the filtration operation, while releasing new filter screen 1233 that has not been filtered.

[0047] It should be noted that in this application, the filter assembly 123 can be controlled by a time relay. When a preset time period is reached, the first roller 1231 and the second roller 1232 are rotated to replace the filter screen 1233. Alternatively, the filter assembly 123 can be controlled by a water pressure differential sensor / wind pressure differential sensor. By monitoring the water pressure differential / wind pressure differential on both sides of the filter screen 1233, when the pressure differential exceeds a certain threshold, it is determined that the filter screen 1233 is clogged, and the filter screen 1233 is replaced. Alternatively, the filter assembly 123 can be controlled by a camera. The filter screen is remotely monitored periodically via images to control the replacement of the filter screen 1233.

[0048] like Figure 2 and Figure 6 As shown, a plurality of guide plates 12112 are provided on the first cavity wall 12111 of the flow cavity 1211, and each guide plate 12112 can rotate synchronously to adjust the flow direction.

[0049] It should be noted that in this application, the guide plate 12112 is movably connected to the first cavity wall 12111 via a mandrel.

[0050] like Figure 2 , Figure 4 and Figure 5 As shown, the refrigeration module 12 also includes a cleaning component 124, which is disposed on the second cavity wall 12113 of the flow cavity 1211. The second cavity wall 12113 is disposed opposite to the first cavity wall 12111. The cleaning component 124 has at least two cleaning ends, which are respectively disposed facing the first cavity wall 12111 and the second cavity wall 12113, for cleaning the first cavity wall 12111 and the second cavity wall 12113. In this way, the two cleaning ends can clean the dirt adhering to the first cavity wall 12111 and the second cavity wall 12113.

[0051] like Figure 2 , Figure 4 and Figure 5As shown, the cleaning assembly 124 includes a guide bracket 1241, a first brush structure 1242, and a second brush structure 1243. The guide bracket 1241 is connected to the second cavity wall 12113 and extends along the extension direction of the flow cavity 1211. The first brush structure 1242 is movably mounted on the guide bracket 1241 and can move along the extension direction of the guide bracket 1241. The brushes of the first brush structure 1242 are positioned near the second cavity wall 12113 for cleaning the second cavity wall 12113. The second brush structure 1243 is connected to the first brush structure 1242 so that the second brush structure 1243 moves with the first brush structure 1242. The brushes of the second brush structure 1243 are positioned near the first cavity wall 12111 for cleaning the first cavity wall 12111. In this way, as the guide bracket 1241 drives the first brush structure 1242 to move up and down, the first brush structure 1242 rubs against the second cavity wall 12113 to clean the second cavity wall 12113; the second brush structure 1243 moves up and down together with the first brush structure 1242 to rub and clean the first cavity wall 12111.

[0052] like Figure 5 As shown, the second brush structure 1243 has a clearance space 1244, which is used to avoid the guide plate 12112. When the cleaning assembly 124 performs cleaning operations, the guide plate 12112 rotates to a state of 90° with the first cavity wall 12111 and extends into the clearance space 1244. In this way, interference between the second brush structure 1243 and the guide plate 12112 can be prevented, thereby affecting the cleaning of the first cavity wall 12111 by the second brush structure 1243.

[0053] It should be noted that, in this application, if Figure 6 As shown, the control system controls the direction of the guide vane 12112 by controlling the spindle at one end of the guide vane 12112, giving the guide vane 12112 three orientations: 45°, 135°, and 90°. Figure 6 (1) represents the 45° direction, (2) represents the 135° direction, and (3) represents the 90° direction. When the guide plate 12112 is in the 45° or 135° direction, the filter screen is in self-cleaning mode. Figure 6The arrows indicate the water flow direction. When the guide plate 12112 is at a 45° angle, the water flows from the back to the front along the guide plate 12112, entering through the back filter screen 1233 and exiting through the front filter screen 1233, thus backwashing the front filter screen 1233. When the guide plate 12112 is at a 135° angle, the water flows from the front to the back along the guide plate 12112, entering through the front filter screen 1233 and exiting through the back filter screen 1233, thus backwashing the back filter screen 1233. This reverse water flow automatically cleans the filter screen 1233. When the guide plate 12112 is at a 90° angle, the cleaning component 124 activates the cleaning mode, and the brush structure cleans the two side walls of the flow chamber 1211.

[0054] like Figure 2 As shown, in the direction from the air outlet of the first air duct section 21 to the air inlet of the computer room module 11, the second air duct section 22 sequentially includes a first heat exchange section 221, a second heat exchange section 222, a third heat exchange section 223, and an air supply box 224. At least a portion of the first heat exchange section 221 and the second heat exchange section 222 are connected to the first air duct section 21. The first heat exchange unit 121 is located inside the first heat exchange section 221. A mixing air valve 23 is provided at the connection between the second heat exchange section 222 and the first air duct section 21. In this way, the cooling mode of the cooling module 12 can be controlled by the opening degree of the mixing air valve 23, ensuring that the temperature of the air flowing into the computer room module 11 from the return air duct 20 remains constant.

[0055] like Figure 2 As shown, the cooling module 12 also includes a second heat exchange section 125. A portion of the second heat exchange section 125 is located within the second heat exchange section 222, while another portion is located outside the casing 10 and submerged in seawater. The second heat exchange section 125 located within the second heat exchange section 222 is downstream of the first heat exchange section 121. Thus, when the temperature of the seawater in the first heat exchange section 121 is insufficient to meet the cooling requirements, the second heat exchange section 125 is activated, allowing both the first and second heat exchange sections 121 to operate together to meet the cooling needs of the subsea data center.

[0056] like Figure 1 and Figure 2 As shown, the second heat exchange section 125 includes a compressor 1251, an evaporator 1252, and a condenser 1253. The compressor 1251 is located within the second heat exchange section 222; the evaporator 1252 is located within the second heat exchange section 222 and downstream of the compressor 1251; the condenser 1253 is located outside the casing 10 and submerged in seawater. Thus, during operation of the second heat exchange section 125, the condenser 1253 can be directly cooled by heat exchange with seawater.

[0057] It should be noted that in this application, the second heat exchange section 125 also includes an electronic expansion valve and various auxiliary components such as temperature sensors, pressure sensors, and a drying filter. The compressor 1251 is the core component of the second heat exchange section 125, installed on the pedal grille 1254 after the side evaporator 1252, and fixed to the pedal grille 1254 with bolts. The condenser 1253 is located outside the rear of the housing 10 and is fixed to the housing 10 by an external bracket. The condenser 1253 has a stainless steel protective mesh to prevent aquatic plants and animals from adhering to its surface and affecting heat exchange. Preferably, the condenser 1253 is made of a water-resistant, corrosion-resistant material. The electronic expansion valve is installed on the pipeline before the condenser 1253 and after the evaporator 1252, which is located between the second heat exchange section 222 and the third heat exchange section 223. Temperature and pressure sensors are installed at both the suction and discharge ports of the compressor 1251 to detect the suction and discharge operating status of the compressor 1251 in the refrigerant refrigeration system. In addition, auxiliary components such as dryer filters are installed on the pipeline, and all components are connected by copper pipes.

[0058] like Figure 1 and Figure 2 As shown, the cooling module 12 also includes a third heat exchange section 126, which is located within the third heat exchange section 223. The air inlet of the third heat exchange section 126 is connected to the air outlet of the second heat exchange section 125, and the air outlet of the third heat exchange section 126 is connected to the air inlet of the air supply box 224. The air outlet of the air supply box 224 is connected to the air inlet of the computer room module 11. In this way, the third heat exchange section 126 can accelerate the circulation of gas within the return air duct 20.

[0059] like Figure 1 and Figure 2 As shown, the third heat exchange section 126 includes multiple fan assemblies 1261, which are arranged in an array within the third heat exchange section 223, and are separated from each other by baffles 1262. In this way, the baffles 1262 can reduce interference between the multiple fan assemblies 1261 and improve the air outlet efficiency.

[0060] It should be noted that in this application, the fan assembly 1261 is arranged in a 4*4 or 9*9 array, with air flowing horizontally from back to front.

[0061] like Figure 1 and Figure 2As shown, the cooling module 12 also includes a second temperature and humidity sensor 127, which is located at the air outlet of the third heat exchange section 126 to detect the temperature and humidity at the air outlet of the third heat exchange section 126. Thus, the second temperature and humidity sensor 127 can detect whether the temperature and humidity T&H2 at the outlet of the fan assembly 1261 reaches the set temperature and humidity T&Hset. When the supply air temperature and humidity T&H2 enters the set temperature and humidity range T&Hset, the opening of the mixing air valve is locked and the current operating mode is maintained to ensure that the temperature of the air flowing into the computer room module 11 from the return air duct 20 remains constant.

[0062] It should be noted that, in this application, if Figure 1 The arrows indicate the direction of air circulation. The computer room module 11 is arranged horizontally to form a double-row micro-module pattern. The micro-module has a sealed heat channel design. The computer room module 11 receives air from the outside and exhausts air into the micro-module. The hot airflow is gathered in the sealed channel and rises along the sealed channel into the first air duct section 21. It enters the air inlet of the first heat exchange section 121 along the first air duct section 21, and after being filtered by the filter component 123, it enters the ventilation cavity 1212 to achieve natural heat exchange with the staggered seawater. The airflow flows out from the air outlet of the ventilation cavity 1212, passes through the compressor 1251 and evaporator 1252 in the second heat exchange section 125, and then passes through the third heat exchange section 126 and the air supply box 224 in sequence, blowing the cooled air after heat exchange back to the computer room module 11 to cool the computer room module 11.

[0063] like Figure 1 and Figure 7 As shown, a first temperature and humidity sensor 122 is provided at the air outlet of the ventilation cavity 1212 to detect whether the air temperature and humidity T&H1 after natural heat exchange has reached the set temperature and humidity, and enter different control modes according to the judgment conditions.

[0064] When the supply air temperature and humidity T&H1 meet the currently set temperature and humidity range, the natural heat exchange operation mode is maintained. At this time, the mixing air valve 23 is closed, the first heat exchange section 121 and the third heat exchange section 126 are in operation, and the second heat exchange section 125 is not started.

[0065] When the supply air temperature and humidity T&H1 is lower than the currently set temperature and humidity range T&Hset, since the seawater temperature cannot be adjusted, the mixing air valve 23 is gradually opened, and the opening of the mixing air valve 23 is gradually adjusted from small to large. A second temperature and humidity sensor 127 is installed at the outlet of the fan assembly 1261 to detect whether the temperature and humidity T&H2 at the outlet of the fan assembly 1261 reaches the set temperature and humidity range T&Hset. When the supply air temperature and humidity T&H2 enters the set temperature and humidity range T&Hset, the opening of the mixing air valve 23 is locked and the current heat recovery operation mode is maintained. At this time, the first heat exchange unit 121 and the third heat exchange unit 126 continue to operate, while the second heat exchange unit 125 does not start operation.

[0066] When the supply air temperature and humidity T&H1 is higher than the currently set temperature and humidity range T&Hset, the natural heat exchange of the first heat exchange unit 121 alone is insufficient to meet the cooling demand. The refrigerant cooling system of the second heat exchange unit 125 must be activated simultaneously to enable compressor 1251 to assist in cooling. Compressor 1251 is frequency-controlled; by adjusting the frequency of compressor 1251's operation, the set supply air temperature and humidity T&Hset can be achieved. At this time, the mixing valve 23 is closed, and the first heat exchange unit 121, the second heat exchange unit 125, and the third heat exchange unit 126 all continue to operate.

[0067] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects: By placing the seabed data center near coastal cities, the speed and smoothness of the network can be improved through short-distance transmission. Because there is little human activity on the seabed, and the temperature and humidity are relatively stable, the interior of the data center is in a relatively stable and controllable environment, which is more suitable for the operation of the server, improves the service life of the equipment, and reduces the frequency of maintenance. The hot air generated by the server room module 11 of the seabed data center is cooled by the cooling module 12 in the return air duct 20. The cooling module 12 has a first heat exchange section 121, which has a flow cavity 1211 and a seawater inlet and a seawater outlet connected to the flow cavity 1211, so as to introduce flowing seawater into the flow cavity 1211 and exchange heat with the hot air in the return air duct 20. The cool seawater is used for natural cooling, which greatly reduces the carbon emissions generated by artificial cooling using air conditioning, reduces energy resource costs, is conducive to sustainable development, saves land resources, and protects the environment.
