Description

Technical Field

[0001] The present application relates to the field of data center heat dissipation technology, and in particular to a data center module. Background Art

[0002] As the scale of data centers continues to expand, the high-performance computing capabilities of data centers also need to be improved, and at the same time, higher requirements are placed on the cooling system of data centers. At present, data centers usually use immersion liquid cooling to dissipate heat from servers. Immersion liquid cooling is to immerse the server directly in the cooling medium, which is placed in a sealed but easily accessible container. The heat is transferred from the server to the cooling medium, thereby achieving heat dissipation for the server.

[0003] In the existing single-phase immersion liquid cooling system, the cooling medium is connected to the cooling tower through a conduit, and the cooling medium after heat exchange is sent to the cooling tower by a circulating pump for heat exchange, and then circulated back to the container. However, the above liquid cooling system requires the installation of a cooling tower, a circulating pump and a heat exchanger, which makes the equipment more complicated and not conducive to rapid deployment. Summary of the invention

[0004] The present application provides a data center module that can be commercialized and simplified for deployment.

[0005] The present application provides a data center module, including a box and a cooling system located in the box. The cooling system may include a spray device, a heat exchange component and a fan. The spray device may be arranged on the top of the box, and the heat exchange component may be arranged on the side of the spray device facing the bottom of the box. The heat exchange component may be filled with a liquid cooling medium, and the liquid cooling medium may be used to absorb the heat of the server immersed in the liquid cooling medium and transfer the heat to the wall surface of the heat exchange component. The spray device may be connected to a cold source, and spray the cooling liquid on the heat exchange component through the cold source. A window assembly is provided on the side wall of the box, and when the window assembly is opened, the gas outside the box can enter the box through the window assembly and exchange heat with the heat exchange component.

[0006] The data center module provided by the present application utilizes a heat exchange component, a spray device, and a natural cold source to exchange heat for the server. Since the heat exchange component can dissipate the heat of the server to the external environment through the wall, when the spray device sprays cooling water on the heat exchange component, the cooling water can be used to take away the heat from the wall of the heat exchange component. When the window component is opened, the gas outside the box can enter the box and exchange heat with the heat exchange component, thereby cooling the server. Due to the above-mentioned data center module mold, the heat exchange component, the spray device, and the fan are all concentrated in the box, which not only makes the data center module commercialized, but also simplifies the module.

[0007] In some possible implementations, the data center module may further include a cold source component, which may include a water pan, a water tank, a water pump, and a water pipe. The water pan may be disposed at the bottom of the housing and is used to receive cooling water after heat exchange with the heat exchange component. The water pump may be connected to the water pan, and the water pump may be connected to a water pipe, which is connected to a water tank, which is connected to a spraying device, and the water pump may be used to transport the cooling water in the water pan to the water tank through the water pipe. After the cooling water exchanges heat with the heat exchange component, it may exchange heat with the gas entering the housing through the window component during the falling process, thereby cooling the cooling water. The cooled cooling water is recirculated back into the water tank to continue spraying the heat exchange component, so as to save costs.

[0008] In some possible implementations, the cooling system may also include a temperature sensor and / or a humidity sensor. The temperature sensor may be used to detect the temperature outside the box, and the humidity sensor may be used to detect the humidity outside the box. In addition, the water source component may also include a water pump switch valve connected to the water pump. The water pump switch valve may turn on or off the water pump according to the detected temperature and humidity outside the box, thereby changing the operation mode of the data center module. When the temperature is low, the water pump can be turned off so that the external gas directly exchanges heat with the heat exchange component. When the temperature is high, the water pump can be turned on and the spray device can be started to exchange heat with the heat exchange component. Different operation modes can make full use of the natural cold source component for heat dissipation, which is conducive to cost saving.

[0009] In some possible implementations, the cooling system may further include a cooling filler, which may be located between the heat exchange component and the water pan. When the cooling water after heat exchange with the heat exchange component falls into the cooling filler, the cooling filler may increase the contact area between the cooling water and the air, thereby better cooling the cooling water, so that the cooling water falling into the water pan may circulate to exchange heat with the heat exchange component.

[0010] In some possible embodiments, the window assembly may include a first window, and the first window may be directly opposite to a portion of the box body between the heat exchange assembly and the cold source. The window assembly may also include a second window, and the second window may be directly opposite to the heat exchange assembly. When the first window and / or the second window are opened, the fan may be used to discharge the gas in the box body.

[0011] In some possible implementation schemes, the cooling system may also be provided with an air valve, which may be used to control the air intake of the first window and the second window when the first window and the second window are opened at the same time, thereby further improving the heat dissipation effect in the box.

[0012] In some possible implementations, the cooling filler may be a wet film, which may increase the evaporation surface area to better cool the cooling water.

[0013] In some possible implementation schemes, the cooling system may further include a water baffle, which may be disposed between the spray device and the fan to prevent cooling water from entering the fan, thereby protecting the fan.

[0014] In some possible implementation schemes, the fan may be disposed between the spray device and the top of the box, or the fan may be disposed between the spray device and the side wall of the box, so that the cooling system design of different box structures can be satisfied.

[0015] In some possible embodiments, the heat exchange assembly may include at least one row of capsule heat exchangers, each row of capsule heat exchangers may include multiple capsule heat exchangers arranged along a first direction, where the first direction is the arrangement direction of two opposite side walls of the box. The spray device may include at least one row of nozzles, each row of nozzles includes multiple nozzles arranged along the first direction. By providing multiple nozzles, the cooling water can be more evenly covered on the surface of the capsule heat exchanger, thereby improving heat exchange.

[0016] In some possible embodiments, the heat exchange assembly may include two rows of capsule heat exchangers, and the two capsule heat exchangers are arranged along the second direction, and the second direction is the arrangement direction from the top to the bottom of the box. The spray device may include two rows of nozzles arranged along the second direction, and each row of nozzles corresponds to each row of capsule heat exchangers. Arranging the capsule heat exchangers in two rows can increase the distance between two adjacent capsule heat exchangers, so that the capsule heat exchangers can dissipate heat better. Arranging two rows of nozzles can enable the upper and lower rows of capsule heat exchangers to evenly receive cooling water.

[0017] In some possible implementations, a water guide device is provided between at least one pair of adjacent capsule heat exchangers in a row of capsule heat exchangers near the spray device, and the water guide device can be used to guide the cooling water after heat exchange in the row of capsule heat exchangers near the spray device directly to the bottom of the box body. In this way, the cooling water after heat exchange in the upper row of capsule heat exchangers will not flow onto the surface of the lower row of capsule heat exchangers, thereby not affecting the heat dissipation effect of the lower row of capsule heat exchangers.

[0018] In some possible embodiments, the heat exchange assembly may include at least one row of capsule heat exchangers, and each row of capsule heat exchangers may include a plurality of capsule heat exchangers arranged along a first direction. The spray device may include at least one water spray cantilever, and the water spray cantilever is provided with a plurality of water spray holes. Each water spray cantilever can rotate relative to the capsule heat exchanger, so that one water spray cantilever can spray cooling water to a plurality of capsule heat exchangers. By making the water spray cantilever movable, the amount of cooling water can be saved, thereby saving costs.

[0019] In some possible implementations, the shape of the capsule heat exchanger may be shuttle-shaped, elliptical, or wing-shaped, so that the capsule heat exchanger has a streamlined structure to reduce wind resistance and facilitate gas circulation in the box.

[0020] In some possible implementation schemes, a plurality of grooves may be provided on the surface of the capsule heat exchanger, each of which may extend from the top to the bottom of the box body, and a hydrophilic treatment may be performed on the surface of the capsule heat exchanger, so that water flows to form a water film on the surface, thereby improving the convective heat transfer coefficient.

[0021] In some possible implementation schemes, the cooling system may also be provided with an air valve, which may be used to control the air intake of the first window and the second window when the first window and the second window are opened at the same time, thereby further improving the heat dissipation effect in the box.

DETAILED DESCRIPTION

[0036] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be limiting of the present application. As used in the specification and appended claims of the present application, the singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0037] References to "one embodiment" or "some embodiments" etc. described in this specification mean that a particular feature, structure or characteristic described in conjunction with the embodiment is included in one or more embodiments of the present application. Thus, the phrases "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear at different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0038] As the scale of data centers continues to expand, the high-performance computing capabilities of data centers also need to be improved, and at the same time, higher requirements are placed on the cooling system of data centers. At present, data centers usually use immersion liquid cooling to dissipate heat from servers. Immersion liquid cooling is to immerse the server directly in the cooling medium, which is placed in a sealed but easily accessible container. The heat is transferred from the server to the cooling medium, thereby achieving heat dissipation for the server.

[0039] In the existing single-phase immersion liquid cooling system, an immersion cabinet is provided, the immersion cabinet is filled with fluorinated liquid, and the server is immersed in the fluorinated liquid. In addition, a cooling water tower and a dry cooler are provided, the cooling water tower can provide cooling water to the dry cooler, and the immersion cabinet and the dry cooler are connected by a pipeline. In this way, the fluorinated liquid in the immersion cabinet after heat exchange with the server can enter the dry cooler through the circulation pump pipeline, and after being cooled, it returns to the immersion cabinet through the circulation pump, thereby completing the cooling cycle.

[0040] However, the above liquid cooling system requires the installation of cooling towers, immersion cabinets, circulation pumps and heat exchangers, which makes the equipment more complicated and not conducive to rapid deployment. In addition, due to the large size of the immersion cabinet, the amount of fluorinated liquid used is large, and the fluorinated liquid in the pipeline has almost no effect on the heat dissipation of the server, so the overall cost is high.

[0041] Based on this, the embodiment of the present application can provide a data center module, which can not only simplify deployment but also reduce costs. The data center module will be described in detail below in conjunction with specific embodiments.

[0042] Please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the data center module in the embodiment of the present application. Figure 2 for Figure 1 A schematic diagram of a cross-sectional structure of a data center module in the embodiment of the present application. The data center module in the embodiment of the present application may include a box 100 and a cooling system located in the box 100. The inside of the box 100 can be used to place the server 10, and the cooling system can exchange heat with the server 10, thereby achieving the effect of cooling the server 10. The box 100 may include a top plate 101, a bottom plate 102, and oppositely disposed first side walls 103 and oppositely disposed second side walls 104. The two first side walls 103 may be arranged along a first direction, the top plate 101 and the bottom plate 102 may be arranged along a second direction, and the two second side walls 104 may be arranged along a third direction. It should be noted that the drawings in the embodiments of the present application are all schematic cross-sectional views of the box 100 along the third direction.

[0043] refer to Figure 2 and Figure 3 , Figure 3 for Figure 2A partial structural diagram of a capsule heat exchanger in FIG. The cooling system may include a spray device 200, a heat exchange component, a cooling filler 300, a cold source component, a water baffle 600, and a fan 500. The heat exchange component may include a plurality of capsule heat exchangers 400, and the plurality of capsule heat exchangers 400 may be evenly arranged along a first direction, and each capsule heat exchanger 400 is filled with a liquid cooling medium, and the liquid cooling medium may be a fluorinated liquid 401, and the server 10 is immersed in the fluorinated liquid 401, and the fluorinated liquid 401 may absorb the heat of the server 10 and dissipate the heat through the wall of the capsule heat exchanger 400.

[0044] The spray device 200 may be disposed near the top plate 101, and may include a plurality of spray heads 201, which may be arranged along the first direction, and each spray head 201 may be disposed one-to-one with the capsule heat exchanger 400. The cooling filler 300 may be located below the capsule heat exchanger 400 and disposed near the bottom plate 102. The cold source assembly may include a water tray 701, a water pump 702, a water pipe 703, and a water tank 704. The water tray 701 may be disposed below the cooling filler 300, and the water tank 704 may be disposed above the spray head 201. The water tray 701 may be connected to the water tank 704 through the water pump 702 and the water pipe 703, and the water tank 704 may be connected to each spray head 201. In addition, the water pump 702 can also be connected to a water pump switch valve, which can control the water pump 702 to be turned on or off, that is, when the cold source component is working, the water pump 702 is turned on, and when the cold source component is not working, the water pump 702 is turned off. It can be understood that after the fluorinated liquid 401 transfers the heat of the server 10 to the capsule heat exchanger 400, the nozzle 201 can spray cooling water on the capsule heat exchanger 400 through the water tank 704, and the cooling water can take away the heat from the wall of the capsule heat exchanger 400. Since the nozzle 201 and the capsule heat exchanger 400 are arranged one by one, the cooling water can be more evenly covered on the capsule heat exchanger 400, thereby ensuring that each capsule heat exchanger 400 is effectively cooled.

[0045] In some other embodiments, the cold source component may also use other cooling liquids to exchange heat with the capsule heat exchanger 400, which is not limited here.

[0046] A window assembly may be provided on the first side wall 103. For example, the window assembly may include a first window 1031 and a second window 1032 provided on each first side wall 103. The first window 1031 may be directly opposite to the cooling filler 300, and the second window 1032 may be directly opposite to the capsule heat exchanger 400. The fan 500 may be disposed above the nozzle 201. A water baffle 600 may be disposed between the nozzle 201 and the fan 500. The water baffle 600 may be used to block the cooling water sprayed by the nozzle 201 to prevent the cooling water from entering the fan 500 and causing damage to the fan 500. The water baffle 600 does not affect the passage of gas, so that the gas can be discharged from the box 100 after passing through the water baffle 600. In some other embodiments, the first window 1031 and the second window 1032 may be opened on only one first side wall 103, or the first window 1031 may be opened on one first side wall 103 and the second window 1032 may be opened on the other first side wall, which is not limited in the embodiments of the present application.

[0047] When the first window 1031 is opened, the outside air can enter the box 100 through the first window 1031. Under the action of the fan 500, the outside air can first pass through the cooling filler 300, then flow upward, and finally be discharged from the box 100, so that the air in the box 100 circulates and promotes the evaporation of cooling water on the surface of the cooling filler 300 and the capsule heat exchanger 400. The cooling water after heat exchange in the capsule heat exchanger 400 can enter the cooling filler 300 under the action of gravity. The cooling filler 300 can increase the surface area of ​​the cooling water in contact with the outside air. Under the action of the outside air, the heated cooling water can be cooled down. The cooled cooling water can fall into the water tray 701 and return to the water tank 704 under the action of the water pump 702, so as to carry out the next spraying.

[0048] In this embodiment, the box body 100 may be a standard container or a customized container, and the box body 100 may be used to accommodate a heat exchange assembly and other components, thereby forming a complete refrigeration system.

[0049] The shape of the capsule heat exchanger 400 can be shuttle-shaped, elliptical or wing-shaped, etc. The above shape can make the capsule heat exchanger 400 have a streamlined structure, thereby reducing wind resistance, so that the fan 500 can discharge external gas from the box 100. In addition, the capsule heat exchanger 400 can also use high thermal conductivity materials, which can facilitate the fluorinated liquid 401 to transfer the heat of the server 10 to the wall surface of the capsule heat exchanger 400. The capsule heat exchanger 400 can also use a flat rib, needle rib or metal foam structure inside to increase the contact area between the fluorinated liquid 401 and the capsule heat exchanger 400, so as to obtain a better heat dissipation effect. The outer surface of the capsule heat exchanger 400 can also be processed with multiple grooves, and the grooves can extend along the second direction, so that the cooling water can flow along the grooves, and the surface of the capsule heat exchanger 400 can also be hydrophilic treated. In this way, not only the contact area between the cooling water and the capsule heat exchanger 400 can be increased, but also the water flow can form a water film on the surface of the capsule heat exchanger 400 as much as possible, thereby improving the convective heat transfer coefficient, thereby achieving the purpose of improving the heat exchange effect.

[0050] There can be two fans 500, and the two fans 500 can be arranged along the first direction, which can improve the circulation efficiency of the external air in the box 100, thereby achieving a better heat dissipation effect. Of course, there can also be multiple fans 500, and multiple fans 500 can also be arranged along the first direction to further improve the circulation efficiency of the gas.

[0051] The cooling filler 300 may be a wet film to increase the contact area between the external air and the cooling water, thereby expanding the evaporation surface area of ​​the cooling water and improving the heat dissipation effect. In some other embodiments, the cooling filler 300 may also be other devices that can expand the evaporation surface area to achieve the purpose of cooling.

[0052] In addition, the cooling system may also be provided with a temperature sensor and a humidity sensor, the temperature sensor may be used to monitor the temperature outside the box 100, and the humidity sensor may be used to monitor the humidity outside the box 100. In this way, the data center module in this embodiment may adopt two working modes in actual application, one is a dry mode with lower temperature and lower humidity, and the other is a wet mode with higher temperature and higher humidity.

[0053] refer to Figure 2 and Figure 4 , Figure 2 It can be understood as the working state of the data center module in wet mode. Figure 4 It can be understood as the working state of the data center module in dry mode. Figure 2As shown, when the temperature and humidity are high, the data center module can work in wet mode. At this time, the first window 1031 is opened and the second window 1032 is closed. The external gas can enter the interior of the box 100 through the first window 1031, and the cold source component is in working state, and the water pump switch valve controls the water pump 702 to turn on. After the nozzle 201 sprays cooling water on the capsule heat exchanger 400, the cooling water after heat exchange with the capsule heat exchanger 400 enters the cooling filler 300 under the action of gravity. When the external gas passes through the cooling filler 300, the cooling water can be cooled. The cooled cooling water falls into the water tray 701, and then returns to the water tank 704 under the action of the water pump 702 and the water pipe 703 to continue the next spraying. Under the action of the fan 500, the gas passing through the cooling filler 300 can further exchange heat with the capsule heat exchanger 400 during the upward flow.

[0054] like Figure 4 As shown, when the temperature and humidity are low, the data center module can work in dry mode. At this time, the first window 1031 is closed, the second window 1032 is opened, and the cold source component is in a non-working state. The water pump switch valve controls the water pump 702 to be closed. It can also be understood that there is no cooling water in the water tank 704. The external gas can enter the box 100 through the second window 1032 and directly exchange heat with the capsule heat exchanger 400. The heat-exchanged gas is discharged from the box 100 under the action of the fan 500. It can also be understood that in the dry mode, there is no need to use a nozzle to exchange heat with the capsule heat exchanger 400, and the heat exchange of the capsule heat exchanger 400 can be completed by natural cooling.

[0055] It should be noted that, in this embodiment, when the data center module operates in wet mode, that is, when the temperature is high, the temperature outside the box 100 is also lower than the temperature of the capsule heat exchanger 400, so that the external gas can exchange heat with the capsule heat exchanger 400.

[0056] In some other embodiments, reference Figure 5 , Figure 5 FIG. 1 is another working state diagram of the data center module in the wet mode in the embodiment of the present application. In this embodiment, a wind valve ( Figure 5(not shown in the figure), the air valve can be used to control the air intake of the first window 1031 and the second window 1032 when both the first window 1031 and the second window 1032 are opened. That is, when the data center module adopts the wet mode, both the first window 1031 and the second window 1032 can be opened, and the external air can enter the interior of the cabinet 100 through the first window 1031 and the second window 1032. The air entering the interior of the cabinet 100 through the first window 1031 passes through the cooling filler 300 and exchanges heat with the falling cooling water, and then is discharged from the cabinet 100 under the action of the fan 500. The air entering the interior of the cabinet 100 through the second window 1032 can directly exchange heat with the capsule heat exchanger 400, and then is discharged from the cabinet 100 under the action of the fan 500. The air valve can control the amount of gas entering the cabinet 100 through the first window 1031 and the amount of gas entering the cabinet 100 through the second window 1032, so as to maximize the efficiency of heat exchange.

[0057] In some embodiments, reference Figure 6 , Figure 6 It is another structural schematic diagram of the data center module in the embodiment of the present application. As mentioned above, there are multiple capsule heat exchangers 400, and the multiple capsule heat exchangers 400 can be arranged in two rows. The two rows of capsule heat exchangers 400 can be arranged along the second direction, and the multiple capsule heat exchangers 400 in each row can be arranged along the first direction. There can be multiple nozzles 201, and the multiple nozzles 201 are arranged along the first direction, and can correspond one-to-one with the capsule heat exchangers 400 in each row, that is, one nozzle 201 can correspond to two capsule heat exchangers 400. It can be understood that when the number of capsule heat exchangers 400 is large, the capsule heat exchangers 400 are divided into two rows to increase the distance between two adjacent capsule heat exchangers 400, thereby avoiding poor heat dissipation due to the small distance between two adjacent capsule heat exchangers 400.

[0058] In some embodiments, reference Figure 7 , Figure 7 This is another structural diagram of the data center module in the embodiment of the present application. When the capsule heat exchangers 400 are divided into two rows, two rows of nozzles 201 arranged along the second direction can also be provided, that is, one row of nozzles 201 can correspond to one row of capsule heat exchangers 400. Since two rows of nozzles 201 are provided, the capsule heat exchangers 400 in the upper row will not affect the spraying of cooling water by the capsule heat exchangers 400 in the lower row, so that the cooling water received by the upper and lower rows of capsule heat exchangers 400 is more even.

[0059] In addition, in this embodiment, a water guide device ( Figure 7(not shown in the figure), after the upper row of capsule heat exchangers 400 exchange heat with the cooling water, the heated cooling water can first fall into the water guide device, and then directly fall into the cooling filler 300 through the water guide device, without contacting the surface of the lower row of capsule heat exchangers 400. In this way, it can be ensured that the lower row of capsule heat exchangers 400 can directly contact the cooling water sprayed by the nozzle 201 to avoid the heated cooling water affecting the heat exchange effect of the lower row of capsule heat exchangers 400. Of course, it should be noted that the water guide device will not affect the amount of cooling water that the lower row of capsule heat exchangers 400 can receive, so that the heat exchange effect of the lower row of capsule heat exchangers 400 can be guaranteed.

[0060] It should be noted that the above embodiments are only for illustration. In actual application, multiple rows of capsule heat exchangers 400 may correspond to one row of nozzles 201, or, multiple rows of capsule heat exchangers 400 may correspond to multiple rows of nozzles 201, or, one nozzle 201 may correspond to multiple capsule heat exchangers 400 in one row, and so on. The embodiments of the present application will not be elaborated here.

[0061] In some embodiments, reference Figure 8 and Fig. 9 , Figure 8 This is another structural diagram of a data center module in an embodiment of the present application. Fig. 9 for Figure 8 The spray device 200 may include two water spray cantilevers 202, which are arranged on the top of the capsule heat exchanger 400, and each water spray cantilever 202 may be connected to the water tank 704. The water spray cantilever 202 may be provided with a plurality of water spray holes, and each water spray hole may spray the capsule heat exchanger 400 with cooling water in the water tank 704. The water spray cantilever 202 may also rotate on the top of the capsule heat exchanger 400 to Fig. 9 For example, the capsule heat exchangers 400 can be distributed not only in the first direction but also in the third direction. The water spray cantilever 202 can spray cooling water on 4×4 capsule heat exchangers 400 during the rotation process, so that each capsule heat exchanger 400 can effectively dissipate heat. In this way, one water spray cantilever 202 can be used to spray cooling water on multiple capsule heat exchangers 400, which can not only save water but also facilitate later maintenance and replacement.

[0062] In some embodiments, reference Fig.10 , Fig.10It is another structural schematic diagram of the data center module in the embodiment of the present application. When two rows of capsule heat exchangers 400 are provided, the spray device 200 may include two rows of water spray cantilevers 202, the two rows of water spray cantilevers 202 are arranged along the second direction, and one row of water spray cantilevers 202 may correspond to one row of capsule heat exchangers 400. The water spray cantilevers 202 may rotate at the top of the capsule heat exchanger 400. The rotation range of the two rows of water spray cantilevers 202 may be the same, so that the cooling water sprayed by the upper and lower rows of capsule heat exchangers 400 can be uniform, thereby achieving a better heat dissipation effect.

[0063] It should be noted that, as mentioned above Figure 8 or Fig.10 In the described embodiment, the number of water spray cantilevers 202 in each row is not limited, and each water spray cantilever 202 can correspond to several capsule heat exchangers 400. In this way, the moving range of the water spray cantilever 202 is small, which can ensure that the capsule heat exchanger 400 can receive cooling water more evenly.

[0064] In some embodiments, reference Fig.11 and Fig.12 , Fig.11 This is another structural diagram of a data center module in an embodiment of the present application. Fig.12 for Fig.11 Another working mode of the data center module in the capsule heat exchanger 400. In this embodiment, the water tank 704 and the nozzle 201 are arranged on the top of the capsule heat exchanger 400, and the water tray 701 is arranged at the bottom of the cooling filler 300, and is connected to the water tank 704 through the water pump 702 and the water pipe 703. The fan 500 can be arranged between the nozzle 201 and the first side wall 103, that is, the fan 500 is not arranged on the top of the nozzle 201, but on the side of the nozzle 201. At this time, the water baffle 600 can be extended as a whole along the second direction to block the nozzle 201 and the fan 500. A flow channel 105 can also be formed between the water baffle 600 and the first side wall 103, so that the external gas can be discharged from the box body 100 through the flow channel 105 under the action of the fan 500.

[0065] In addition, in this embodiment, a first window 1031 and a second window 1032 may be provided on the first side wall 103 away from the fan 500, and external gas may enter the box 100 through the first window 1031 and the second window 1032, and may be discharged from the box 100 after heat exchange with the capsule heat exchanger 400. The cooling filler 300 may be in a certain tilted state with respect to the first side wall 103, and the bottom of the cooling filler 300 may be tilted toward the fan 500, so as to reduce wind resistance and facilitate better circulation of gas in the box 100. Similarly, the water baffle 600 may also be in an inclined state, and the bottom of the water baffle 600 may be tilted toward the fan 500, so as to facilitate better flow of gas. In addition, a baffle 800 may be provided between the water baffle 600 and the cooling filler 300, and a baffle 800 may also be provided between the side of the cooling filler 300 close to the first window 1031 and the first side wall 103, so that a relatively closed space is formed between the capsule heat exchanger 400 and the cooling filler 300. In this way, the cooling water after heat exchange with the capsule heat exchanger 400 can fall into the water tray 701 after passing through the cooling filler 300, rather than falling into the water tray 701 directly, so that the cooling effect of the cooling water can be improved through the cooling filler 300.

[0066] The data center module in this embodiment can also adopt dry mode and wet mode working modes, such as Fig.10 As shown, when the wet mode is adopted, the first window 1031 is opened, the external gas enters the box body 100 through the first window 1031, and the cooling water source is in working state. After the nozzle 201 sprays cooling water on the capsule heat exchanger 400, the cooling water after heat exchange with the capsule heat exchanger 400 enters the cooling filler 300 under the action of gravity, and the external gas passes through the cooling filler 300, which can cool the cooling water. The cooled cooling water falls into the water tray 701, and then returns to the water tank 704 under the action of the water pump 702 and the water pipe 703, and continues the next spraying. Under the action of the fan 500, a part of the gas passing through the cooling filler 300 can flow upward, and further exchange heat with the capsule heat exchanger 400, and finally enter the flow channel 105 through the water baffle 600, and is discharged from the box body 100 under the action of the fan 500. Another part of the gas that has passed through the cooling filler 300 can directly enter the flow channel 105 and be discharged from the box body 100 under the action of the fan 500 .

[0067] refer to Fig.11 When the dry mode is used, the first window 1031 is closed, the second window 1032 is opened, and the cold source assembly is in a non-operating state, that is, there is no cooling water in the water tank 704. External gas can enter the box body 100 through the second window 1032 and directly exchange heat with the capsule heat exchanger 400. The heat-exchanged gas passes through the water baffle 600 and enters the flow channel 105, and is discharged from the box body 100 under the action of the fan 500.

[0068] It should be noted that, since the drawings in the embodiments of the present application are only used as examples to illustrate the cross-sectional structure of the data center module, in actual application, multiple capsule heat exchangers can be arranged not only along the first direction, but also along the third direction, that is, multiple capsule heat exchangers can be distributed in an array. Correspondingly, multiple nozzles can also be distributed in an array, which will not be described here.

[0069] Compared with the traditional data center, the data center module in the embodiment of the present application can maximize the use of natural cold sources, and adopts the form of natural cold source + spraying to dissipate heat from the capsule heat exchanger, and the cooling water sprayed on the surface of the capsule heat exchanger can form a liquid film, which accelerates the downward flow under the action of gravity, increasing the convective heat transfer coefficient, thereby not only improving the heat exchange effect of the capsule heat exchanger, but also saving costs. In addition, all modules are concentrated in the box, eliminating the cooling tower, and the data center module is commercialized, simplifying the deployment. In addition, it also solves the problem of large amount of fluorinated liquid used in the prior art, eliminating the fluorinated liquid in the pipeline, and reducing the initial investment cost in the fluorinated liquid.

[0070] The above are only specific implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
