Description

Technical Field

[0001] This invention relates to the field of air conditioning system technology, and more specifically to a data center heat exchange system. Background Technology

[0002] Currently, data centers often use near-end cooling units, such as indirect evaporative cooling units and integrated refrigerant pump units, which are located close to the computer room for cooling. Each computer room area is equipped with an independent near-end cooling unit, and the cooled air is directly sent into the adjacent computer room, resulting in high cooling efficiency.

[0003] In related technologies, near-end cooling units use outdoor exhaust ventilation, with each unit exhausting through a separate duct. To prevent hot exhaust air from being drawn in and affecting cooling efficiency, the exhaust vents must be higher than the air inlets of the units on the highest floor. However, due to the limited residual pressure of the unit's exhaust fans, the duct resistance cannot be too high, otherwise it will lead to poor ventilation. Furthermore, increasing the duct height will increase exhaust resistance, thus limiting the duct height and consequently restricting the building height of data centers. Typically, one to four-story buildings are used, occupying a large space and resulting in low land utilization. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, embodiments of the present invention propose a data center heat exchange system that can meet the exhaust requirements of higher building floors, thereby enabling the construction of data centers with more floors and improving land utilization.

[0006] The data center heat exchange system of this invention includes an exhaust shaft and multiple building structures, with at least two of the building structures spaced apart. Each building structure includes at least one floor, and each floor is equipped with a cold source device and at least one computer room. The cold source device includes an indoor heat exchange channel and an outdoor heat exchange channel. The indoor heat exchange channel has an air supply end and a return air end connected to the computer room, and the outdoor heat exchange channel has an air inlet end and an exhaust end. The exhaust shaft is located between the at least two spaced-apart building structures, and the exhaust end is connected to the exhaust shaft. The upper end of the exhaust shaft is open to form an exhaust vent. Hot air from the computer room enters the indoor heat exchange channel through the return air end, undergoes heat exchange in the indoor heat exchange channel, and then enters the computer room through the air supply end. Cold air from outside the computer room enters the outdoor heat exchange channel through the air inlet end, undergoes heat exchange in the outdoor heat exchange channel, and then is discharged into the exhaust shaft through the exhaust end.

[0007] Optionally, the data center heat exchange system further includes a side enclosure structure and a bottom enclosure structure, the side enclosure structure and the bottom enclosure structure forming the exhaust shaft, the bottom enclosure structure sealing the lower end of the side enclosure structure and connecting to the side enclosure structure, and the upper end of the side enclosure structure being open to form the exhaust vent.

[0008] Optionally, the side enclosure structure includes a side frame and a side panel, the side panel being connected to the side frame; and / or, the bottom enclosure structure includes a bottom frame and a bottom panel, the bottom panel being connected to the bottom frame; and / or, the data center heat exchange system further includes a support structure, the support structure being connected to the side enclosure structure and / or the bottom enclosure structure, the support structure having a first support end for supporting on the ground and a second support end connected to the building body.

[0009] Optionally, the lower side of the bottom enclosure structure is higher than the first support end of the support structure to form a passage space on the lower side of the bottom enclosure structure.

[0010] Optionally, the bottom enclosure structure has a through-hole drainage outlet that is connected to the ventilation shaft.

[0011] Optionally, the building floor includes an installation platform located on the side of the machine room near the exhaust shaft, the cold source equipment is located on the installation platform, and an air intake area is formed between the air intake end of the cold source equipment and the exhaust shaft, the air intake end being connected to the air intake area; and / or, the building floor further includes an exhaust duct, one end of which is connected to the exhaust end, and the other end of which is connected to the exhaust shaft.

[0012] Optionally, the installation platform has a first side and a second side arranged opposite to each other in a first direction. The first side of the installation platform is located close to the machine room, and the second side of the installation platform is spaced apart from the exhaust shaft. The installation platform also has a third side and a fourth side arranged opposite to each other in a second direction. The two ends of the first direction point to the machine room and the exhaust shaft, respectively, and the first direction is perpendicular to the second direction. The building floor includes a second side wall, a third side wall, and a fourth side wall. The second side wall is connected to the second side of the installation platform, the third side wall is connected to the third side of the installation platform, and the fourth side wall is connected to the fourth side of the installation platform. The second side wall, the third side wall, and the fourth side wall enclose an air intake space, which is connected to the air intake end of the cold source equipment. The air intake space forms part of the air intake area.

[0013] Optionally, the side of the second sidewall away from the cold source device forms an air inlet chamber, which is connected to the air inlet space and forms part of the air inlet area; and / or, at least one of the third sidewall and the fourth sidewall has an air inlet channel, which is connected to the air inlet space.

[0014] Optionally, the upper end of the second side wall is lower than the top wall of the building layer; and / or, the upper end of the third side wall is attached to the top wall of the building layer; and / or, the upper end of the fourth side wall is attached to the top wall of the building layer.

[0015] Optionally, the exhaust shaft and the two building bodies together constitute a heat exchange system group, with the two building bodies of the heat exchange system group arranged at intervals and opposite to each other on both sides of the exhaust shaft. There are multiple heat exchange system groups, with at least two heat exchange system groups arranged sequentially along the interval direction between the two building bodies in the same group; and / or, there are multiple building bodies, with the multiple building bodies arranged evenly in a circle along the center line of the exhaust shaft; and / or, the building body includes at least four building layers arranged sequentially in the vertical direction.

[0016] In the data center heat exchange system of this invention, the exhaust shafts are located on the outside of the building. Therefore, the size of the exhaust shafts is not limited. The size of the exhaust shafts can be reasonably designed according to parameters such as the height and number of building floors, the number of computer rooms, the number of cold source equipment, and air volume. For example, the cross-sectional area of ​​the exhaust shaft can be increased to reduce the exhaust resistance inside the exhaust shaft, making the exhaust smooth and thus meeting the exhaust needs of each building floor. Therefore, the data center heat exchange system of this invention can meet the exhaust needs of higher building floors (e.g., four floors or more), thereby enabling the construction of data centers with more floors and improving land utilization.

[0017] In addition, the exhaust vents are located at the top of the exhaust shaft. Hot air discharged from multiple cooling source devices in multiple buildings enters the exhaust shaft and is discharged from the top of the exhaust shaft to the top of the data center, thereby preventing the discharged hot air from being re-inhaled by the cooling source devices and affecting the cooling efficiency.

[0033] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0034] like Figures 1 to 3 As shown, the data center heat exchange system of this embodiment includes an exhaust shaft 1 and multiple building bodies 2, with at least two building bodies 2 spaced apart. Each building body 2 includes at least one building floor 21, which is equipped with a cold source device 3 and at least one computer room. The cold source device 3 includes an indoor heat exchange channel and an outdoor heat exchange channel. The indoor heat exchange channel has an air supply end and a return air end connected to the computer room, and the outdoor heat exchange channel has an air inlet end and an air outlet end. The exhaust shaft 1 is located between at least two spaced-apart building bodies 2, with the air outlet end connected to the exhaust shaft 1. The upper end of the exhaust shaft 1 is open to form an exhaust vent 11. Hot air in the computer room enters the indoor heat exchange channel from the return air end, and after heat exchange in the indoor heat exchange channel, it enters the computer room through the air supply end. Cold air outside the computer room enters the outdoor heat exchange channel from the air inlet end, and after heat exchange in the outdoor heat exchange channel, it is discharged into the exhaust shaft 1 through the exhaust end.

[0035] In the data center heat exchange system of this invention, the exhaust shaft 1 is located between multiple buildings 2. The exhaust ends of the cold source equipment 3 installed on the multiple buildings 2 are all connected to the exhaust shaft 1, and the hot air generated by heat exchange in the computer room is discharged through the exhaust shaft 1. That is, multiple buildings 2 share one exhaust shaft 1 for exhaust. The hot air in the multiple buildings 2 is discharged into the exhaust shaft 1 and discharged upward into the outdoor environment through the exhaust port 11.

[0036] The exhaust shaft 1 is located on the outside of the building 2, so the size of the exhaust shaft 1 is not limited. The size of the exhaust shaft 1 can be reasonably designed according to parameters such as the height and number of building floors 21, the number of computer rooms, the number of cold source equipment 3, and the air volume. For example, the cross-sectional area of ​​the exhaust shaft 1 can be increased to reduce the exhaust resistance inside the exhaust shaft 1, so that the exhaust can be smooth and meet the exhaust needs of each building floor 21. Therefore, the data center heat exchange system of this embodiment can meet the exhaust needs of higher building floors 21 (e.g., four floors or more), and thus data centers with more floors can be built, improving land utilization.

[0037] In addition, the exhaust vent 11 is located at the top of the exhaust shaft 1. The hot air discharged from the multiple cooling source devices 3 of the multiple building bodies 2 enters the exhaust shaft 1 and is discharged from the top of the exhaust shaft 1 to the top of the data center, thereby preventing the discharged hot air from being re-inhaled by the cooling source devices 3 and affecting the cooling efficiency.

[0038] Optionally, the cooling source equipment can be an indirect evaporative cooling unit or an integrated fluorine pump unit.

[0039] As an example, when the cooling source equipment is an integrated refrigerant pump unit, the cooling source equipment 3 includes structures such as an indoor fan, an outdoor fan, an evaporator, and a condenser. The indoor fan drives the air in the machine room to enter the indoor heat exchange channel from the return air end and exit from the supply air end to achieve indoor airflow circulation. The evaporator absorbs the heat of the indoor airflow when the indoor hot air flows through the indoor heat exchange channel, thereby reducing the temperature of the indoor hot air. The outdoor fan drives the air outside the machine room to enter the outdoor heat exchange channel from the air inlet end and exit from the air outlet end to achieve outdoor airflow circulation. The condenser transfers heat to the outdoor airflow when the outdoor cold air flows through the outdoor heat exchange channel, thereby achieving the transfer of indoor airflow temperature to outdoor airflow temperature and realizing the cooling operation of the machine room.

[0040] It is understandable that the specific composition of the cold source equipment is a technology well known to those skilled in the art, and will not be described in detail here.

[0041] As an example, such as Figures 1 to 3 As shown, building 2 is the server room building of the data center, and building floor 21 is the floor. There are two buildings 2, which are arranged opposite each other on both sides of exhaust shaft 1. The exhaust ends of multiple cold source devices 3 are all connected to the exhaust shaft 1, that is, the hot air discharged from multiple cold source devices 3 on the two buildings 2 is discharged to the outdoor environment through the same exhaust shaft 1.

[0042] like Figure 4 and Figure 5 As shown, the building 2 includes multiple building floors 21, which are arranged sequentially from bottom to top. Each building floor 21 has at least one computer room, and the computer room has multiple server racks 211. The server racks 211 are arranged sequentially at intervals along the width of the building floor 21, and a cold aisle 213 is formed between two adjacent server racks 211. Each server rack 211 is equipped with a corresponding cold source device 3. A static pressure chamber 212 is provided between the cold source device 3 and the computer room. The static pressure chamber 212 extends along the width of the building floor 21 and is connected to the internal space of the computer room. The air supply end of the cold source device 3 is connected to the static pressure chamber 212 through an air supply duct. Thus, the hot air in the computer room is cooled by the cold source device 3, and then sent into the computer room through the static pressure chamber 212 and enters the cold aisle 213, forming a positive pressure environment in the cold aisle 213, which is then used for heat exchange and cooling of the multiple server racks 211.

[0043] Each rack group 211 includes two rows of IT racks 2111. The two rows of IT racks 2111 in the same rack group 211 are spaced apart along the width direction of the building floor 21, forming a hot aisle 214 between the two rows of IT racks 2111. The top wall of the server room is spaced apart from the top wall of the building floor 21, forming a hot return air chamber 215 between the top wall of the server room and the top wall of the building floor 21. The hot return air chamber 215 is formed directly above the hot aisle 214. The top wall of the server room has an opening that runs through the hot aisle 214. The passage 214 is connected to the hot return air chamber 215 through the opening. The hot return air chamber 215 is connected to the return air end of the cold source equipment 3 through the return air duct, which is located above the supply air duct. Thus, the hot air generated by the heat exchange of the two rows of IT cabinets 2111 in the same cabinet group 211 passes through the hot passage 214 and the hot return air chamber 215 in sequence and is then drawn into the cold source equipment 3 from the return air end. A negative pressure environment is formed in the hot passage 214 and the hot return air chamber 215. After the hot air is heat exchanged by the cold source equipment 3, the temperature is reduced and it is discharged into the computer room from the supply air end, thereby achieving computer room cooling.

[0044] The hot aisle 214 and the cold aisle 213 are not connected to each other. Cold air can enter the hot aisle 214 after passing through the IT cabinet 2111 or other power equipment such as power heat exchange equipment in the computer room from the cold aisle 213, thereby reducing heat loss and improving cooling efficiency.

[0045] like Figure 1 and Figure 2 As shown, the computer rooms mentioned above and below are all IT computer rooms. Building floor 21 also includes a power room 216 and a corridor 217. The power room 216 is located on the side of the computer room away from the chiller unit. The corridor 217 is located between the power room 216 and the computer room, allowing maintenance personnel to walk around. The power room 216 is also equipped with a heat exchange and cooling system. The heat exchange and cooling system of the power room 216 is different from the heat exchange system of the IT computer room, and will not be described in detail here.

[0046] In some embodiments, the data center heat exchange system further includes a side enclosure structure 12 and a bottom enclosure structure 13, which together form an exhaust shaft 1. The bottom enclosure structure 13 blocks the lower end of the side enclosure structure 12 and is connected to the side enclosure structure 12, while the upper end of the side enclosure structure 12 is open to form the exhaust vent 11.

[0047] like Figure 1 and Figure 2 As shown, when two buildings 2 share a ventilation shaft 1, the cross-section of the side enclosure structure 12 is rectangular, that is, the cross-section of the ventilation shaft 1 is rectangular, and the two buildings 2 are arranged opposite each other on both sides of the ventilation shaft 1.

[0048] Optionally, such as Figure 1 and Figure 2 As shown, the cross-sectional dimensions of the side enclosure structure 12 remain consistent from top to bottom, which is more conducive to the construction and installation of the side enclosure structure 12 and the bottom enclosure structure 13.

[0049] Optionally, such as Figure 1 As shown, the upper end of the side enclosure structure 12 is higher than the top wall of the building 2, so that an exhaust vent 11 higher than the data center computer room building is formed at the upper end of the side enclosure structure 12. Hot air is discharged to the upper side of the data center through the exhaust vent 11, thereby avoiding the exhaust hot air being re-inhaled by the cold source equipment 3 and affecting the cooling efficiency.

[0050] In some embodiments, the side enclosure structure 12 includes a side frame and a side panel, with the side panel connected to the side frame.

[0051] In some embodiments, the bottom enclosure structure 13 includes a bottom frame and a bottom panel, with the bottom panel connected to the bottom frame.

[0052] In some embodiments, the data center heat exchange system further includes a support structure 14, which is connected to the side enclosure structure 12 and / or the bottom enclosure structure 13. The support structure 14 has a first support end 141 for supporting on the ground and a second support end 142 connected to the building body 2.

[0053] The support structure 14 forms the main support frame of the ventilation shaft 1, which is used to bear the core load. The first support end 141 of the support structure 14 is supported on the ground, and the second support end 142 of the support structure 14 is connected to and supported on the building body 2, thereby providing a stable foundation for the construction of the ventilation shaft 1 and ensuring the overall strength of the ventilation shaft 1.

[0054] Both the side frame and the bottom frame are connected to the support structure 14. The side frame and the bottom frame are further connected between the support structure 14 to form the overall frame structure of the ventilation shaft 1, providing an installation foundation for the side panels and the bottom panels.

[0055] Multiple bottom and side panels can be used to form an exhaust shaft 1 with only an opening at the top. This ensures the airtightness of the side and bottom walls of the exhaust shaft 1, preventing hot air leakage from the side or bottom walls of the exhaust shaft 1 from being drawn into the air inlet of the cold source equipment 3 and affecting the cooling efficiency.

[0056] Optionally, at least one of the side frame, bottom frame and support structure 14 is made of profiles (e.g., structural columns, beams, etc.).

[0057] Optionally, at least one of the side panels and the bottom panel may be made of a sheet material such as steel plate, wood board or composite board.

[0058] Optionally, at least one of the side panels and the bottom panel may be covered with thermal insulation material.

[0059] Specifically, such as Figure 1 and Figure 4 As shown, the side frame, bottom frame, and supporting structure 14 are all made of structural columns, beams, and other profiles. The supporting structure 14 includes a first supporting frame and a second supporting frame. At least a portion of the first supporting frame extends vertically, and its lower end is supported on the ground, forming the aforementioned first supporting end 141. At least a portion of the second supporting frame extends horizontally, with one side of the second supporting frame fixedly connected to the first supporting frame, and the other side of the second supporting frame fixedly connected to the building body 2, forming the aforementioned second supporting end 142. The side frame, bottom frame, first supporting frame, and second supporting frame are fixed to each other by welding or bolting, thereby forming an integral frame structure.

[0060] Both the side panels and the bottom panels are made of steel plates, wood boards, or composite boards. The side panels are fixedly connected to the side frames, and the bottom panels are fixedly connected to the bottom frames. Multiple bottom panels and side panels can be used to form an exhaust shaft 1 with only an opening at the top, so as to ensure the airtightness of the side walls and bottom walls of the exhaust shaft 1, prevent hot air leakage from the side walls or bottom walls of the exhaust shaft 1, and improve the exhaust efficiency.

[0061] Of course, in other embodiments, the bottom enclosure structure 13 and the side enclosure structure 12 can also be constructed of concrete. Those skilled in the art can choose an appropriate construction method based on the actual situation such as site and cost, which will not be elaborated here.

[0062] In some embodiments, such as Figure 1 As shown, the lower side of the bottom enclosure structure 13 is higher than the first support end 141 of the support structure 14, so as to form a channel space 15 on the lower side of the bottom enclosure structure 13.

[0063] In other words, a passage space 15 is formed on the lower side of the exhaust shaft 1, which can be used as a pedestrian and / or vehicle passage to improve the accessibility of the data center.

[0064] Specifically, such as Figure 1 As shown, the lower side of the bottom enclosure structure 13 is lower than the lowest exhaust pipe 4 and higher than the ground, supporting the structure 14, thereby forming the aforementioned passage space 15 on the lower side of the bottom enclosure structure 13, improving the accessibility of the data center.

[0065] In some embodiments, the bottom enclosure structure 13 has a through-hole drainage outlet that is connected to the ventilation shaft 1.

[0066] By setting up drainage outlets, rainwater and snowmelt water in ventilation well 1 can be discharged, preventing water accumulation in ventilation well 1.

[0067] Optionally, the drain outlet is equipped with a sealing device to prevent high-temperature airflow from leaking out of the drain outlet.

[0068] Specifically, the bottom enclosure structure 13 has an upward-facing drainage surface that forms the bottom wall of the drainage well. The drainage surface is sloped for single-sided or double-sided drainage, and the drainage outlet is located at the lowest point of the drainage surface to ensure drainage efficiency.

[0069] In addition, depending on the construction site of building 2, snow melting facilities can be installed in the ventilation shaft 1 to prevent snow accumulation on the bottom wall of the drainage shaft during winter.

[0070] In some embodiments, the building floor 21 includes an installation platform 22, which is located on the side of the machine room near the exhaust shaft 1. The cold source equipment 3 is located on the installation platform 22, and an air intake area is formed between the air intake end of the cold source equipment 3 and the exhaust shaft 1. The air intake end is connected to the air intake area.

[0071] The air intake area is formed on the side of the exhaust shaft 1. Specifically, the area on the side of the exhaust shaft 1 corresponding to the height of the building floor 21 forms the air intake area of ​​the cold source equipment 3 of the building floor 21. The air intake areas of two adjacent building floors 21 are connected to each other through the gap of the second support frame. The air intake area is directly connected to the outdoor environment, and the cold air in the outdoor environment directly enters the air intake end of the cold source equipment 3 through the air intake area.

[0072] In other words, the air intake airflow of each cold source device 3 in the data center is formed near the installation platform 22 where the cold source device 3 is located. Since the exhaust airflow of the cold source device 3 is discharged through the exhaust port 11 at the top of the exhaust shaft 1, the direction and position of the air intake airflow and the exhaust airflow of the data center heat exchange system are different and independent of each other. This can prevent the air intake airflow of the cold source device 3 from being affected by the exhaust airflow, and prevent the air intake airflow and exhaust airflow from mixing, which would cause the air intake airflow temperature of the cold source device 3 to rise, thereby improving the cooling capacity of the cold source device 3 and reducing energy consumption.

[0073] In addition, the independence of the intake airflow and the exhaust airflow is more conducive to the independent design of the exhaust shaft 1 and the intake area, which can simultaneously meet the design requirements of the number of building floors 21, the number of cold source equipment 3 installed on a single building floor 21, and the air volume of the near-end cold source equipment 3.

[0074] Optionally, the installation platform 22 is made of concrete. Compared with the installation platform 22 with a grid structure, the installation platform 22 with a concrete structure has higher strength, which can improve the safety of maintenance personnel.

[0075] like Figure 1 and Figure 4 As shown, the bottom wall of the building layer 21 extends towards the side of the machine room near the exhaust shaft 1 to form an installation platform 22. The installation platform 22 is located on the side of the static pressure chamber 212 away from the machine room. The cold source equipment 3 is installed on the upper side of the installation platform 22. The second support frame of the support structure 14 is connected to the installation platform 22 to improve the stability of the exhaust shaft 1.

[0076] In some embodiments, such as Figure 1 and Figure 4 As shown, the building floor 21 also includes an exhaust pipe 4, one end of which is connected to an exhaust end, and the other end of which is connected to an exhaust shaft 1.

[0077] The hot air discharged from the exhaust end of the cold source equipment 3 enters the exhaust shaft 1 directly through the exhaust pipe 4, and then is discharged through the exhaust port 11 at the upper end of the exhaust shaft 1. This can prevent the hot air from mixing with the cold air in the air intake area during the process of the hot air being discharged from the cold source equipment 3 into the exhaust shaft 1, thereby reducing the unit energy consumption of the cold source equipment 3.

[0078] In some embodiments, such as Figure 1 and Figure 2 As shown, the installation platform 22 has a first side and a second side arranged opposite to each other in a first direction. The first side of the installation platform 22 is located close to the machine room, and the second side of the installation platform 22 is spaced apart from the exhaust shaft 1. The installation platform 22 has a third side and a fourth side arranged opposite to each other in a second direction. The two ends of the first direction point to the machine room and the exhaust shaft 1, respectively, and the first direction is perpendicular to the second direction. The building layer 21 includes a second side wall 23, a third side wall 24, and a fourth side wall 25. The second side wall 23 is connected to the second side of the installation platform 22, the third side wall 24 is connected to the third side of the installation platform 22, and the fourth side wall 25 is connected to the fourth side of the installation platform 22. The second side wall 23, the third side wall 24, and the fourth side wall 25 enclose an air intake space 26, which is connected to the air intake end of the cold source equipment 3. The air intake space 26 forms part of the air intake area.

[0079] The first direction and the second direction both extend horizontally. The two ends of the first direction point to the machine room and the ventilation shaft 1, respectively. The second direction is perpendicular to the first direction, that is, the second direction is consistent with the width direction of the building 2.

[0080] The first side of the installation platform 22 is located close to the machine room. The second, third and fourth sides of the installation platform 22 are all equipped with side walls, which can improve the safety of operators working on the installation platform 22. At the same time, the cold source equipment 3 is installed on the installation platform 22. The second side wall 23, the third side wall 24 and the fourth side wall 25 can protect the cold source equipment 3 from damage caused by storms, rain and snow.

[0081] In some embodiments, an air inlet chamber 27 is formed on the side of the second sidewall 23 away from the cold source device 3. The air inlet chamber 27 is connected to the air inlet space 26 and forms part of the air inlet area.

[0082] like Figure 1 and Figure 4 As shown, the air intake chamber 27 is formed in the gap between the building body 2 and the exhaust shaft 1. The top of the building body 2 is connected to a top surface enclosure structure. The side of the top surface enclosure structure away from the building body 2 is fixedly connected to the side enclosure structure 12 of the exhaust shaft 1. The projection of the top surface enclosure structure on the horizontal plane can completely cover the air intake chamber 27, so as to achieve the closure of the air intake chambers 27 of all building floors 21.

[0083] Optionally, the top enclosure structure includes a top frame and a top panel. The top frame is fixedly connected to the top wall of the building 2 and the side enclosure structure 12, and the top panel is fixedly connected to the top frame.

[0084] In some embodiments, at least one of the third sidewall 24 and the fourth sidewall 25 has an air intake channel 28, which communicates with the air intake space 26.

[0085] The outdoor fan of the cold source equipment 3 draws in cold air from the air inlet, creating a negative pressure in the air inlet space 26. This creates a negative pressure difference between the air inlet space 26 and the outdoor environment. Part of the cold air from the outdoor environment enters the air inlet space 26 through the air inlet channel 28, and the other part enters the air inlet space 26 through the air inlet chamber 27. The indoor fan of the cold source equipment 3 discharges the hot air generated by the heat exchange of the IT cabinet 2111 into the exhaust shaft 1 through the exhaust pipe 4. This creates a positive pressure in the exhaust shaft 1, creating a positive pressure difference between the exhaust shaft 1 and the outdoor environment. Under the action of the pressure difference, the airflow in the exhaust shaft 1 is discharged into the atmosphere above the data center through the exhaust port 11.

[0086] With the above settings, cold air from the outdoor environment can enter the air intake space 26 through two pathways: the air intake chamber 27 and the air intake channel 28, and then enter the cold source device 3, providing sufficient cold air for the cold source device 3 and meeting its air intake requirements.

[0087] In some embodiments, the upper end of the second sidewall 23 is lower than the top wall of the building layer 21.

[0088] Therefore, there is a certain space between the upper side of the second side wall 23 and the top wall of the building layer 21, so that the air intake space 26 and the air intake chamber 27 on both sides of the second side wall 23 can be connected to each other, and then cold air is introduced into the air intake end of the cold source equipment 3 through the air intake chamber 27 and the air intake space 26.

[0089] Optionally, the second side wall 23 is a guardrail.

[0090] Therefore, the air intake space 26 and the air intake chamber 27 can also be connected through the gaps in the guardrail, thereby increasing the connection area between the air intake space 26 and the air intake chamber 27 and improving the air intake efficiency.

[0091] like Figure 1 and Figure 4 As shown, the air intake space 26 and the air intake chamber 27 are connected through the upper space of the second side wall 23, so that the cold air from the outdoor environment enters the cold source equipment 3 through the air intake chamber 27 and the air intake space 26. The exhaust duct 4 extends horizontally and passes through a part of the air intake space 26, the upper space of the second side wall 23 and the air intake chamber 27 in sequence. One end of the exhaust duct 4 is connected to the exhaust end of the cold source equipment 3, and the other end of the exhaust duct 4 extends through the side enclosure structure 12 into the exhaust shaft 1, so that the hot air discharged from the cold source equipment 3 enters the exhaust shaft 1 through the exhaust duct 4.

[0092] To ensure that the size of the air inlet chamber 27 meets the air intake requirements, the size of the air inlet chamber 27 needs to be increased accordingly. The exhaust duct 4 passes through the air inlet chamber 27, resulting in a corresponding increase in the length of the exhaust duct 4 and an increase in exhaust resistance. In this embodiment of the invention, by rationally designing the diameter and arrangement of the exhaust duct 4, the resistance of the exhaust airflow within the exhaust duct 4 can be reduced, thereby reducing exhaust resistance and controlling the exhaust resistance loss within the effective residual pressure provided by the outdoor fan of the cold source equipment 3, ensuring smooth exhaust.

[0093] In some embodiments, the upper end of the third sidewall 24 is attached to the top wall of the building layer 21.

[0094] In some embodiments, the upper end of the fourth sidewall 25 is attached to the top wall of the building layer 21.

[0095] The third and fourth sides of the mounting platform 22 are enclosed by the third side wall 24 and the fourth side wall 25 respectively, which can improve the protection effect on the cold source equipment 3.

[0096] Optionally, air inlet louvers are provided on both the third side wall 24 and the fourth side wall 25, and the air inlet channel 28 is formed in the air inlet louvers.

[0097] By using the air intake louvers, dust, rain, snow and other debris in the outdoor environment can be blocked from entering the air intake space 26 through the air intake channel 28, which provides good protection for the cold source equipment 3 on the installation platform 22. At the same time, the air intake space 26 can be connected to the outdoor environment through the air intake louvers to ensure smooth air intake.

[0098] In some embodiments, the exhaust shaft 1 and two building bodies 2 together constitute a heat exchange system group. The two building bodies 2 of the heat exchange system group are arranged at intervals and opposite to each other on both sides of the exhaust shaft 1. There are multiple heat exchange system groups, and at least two heat exchange system groups are arranged sequentially along the interval direction of the two building bodies 2 in the same group.

[0099] As an example, such as Figure 6 As shown, there are two heat exchange system groups, which are arranged in sequence. The two heat exchange system groups are close to each other and the building 2 is merged into one to form a large computer room building. The exhaust pipes 4 on both sides of the computer room building are connected to the exhaust shafts 1 on both sides respectively.

[0100] As an example, such as Figure 7 As shown, there are three heat exchange system groups, which are arranged in sequence. The building 2 of two adjacent heat exchange system groups is merged into one, forming a large computer room building. The exhaust pipes 4 on both sides of the computer room building are connected to the exhaust shafts 1 on both sides respectively.

[0101] In some embodiments, such as Figures 8 to 10 As shown, there are multiple building bodies 2, which are evenly arranged in a circle along the center line of the ventilation shaft 1.

[0102] As an example, such as Figure 8 As shown, there are three building bodies 2. The three building bodies 2 are evenly arranged in a circle along the center line of the exhaust shaft 1. The cross-section of the exhaust shaft 1 is an equilateral triangle, that is, the exhaust shaft 1 has three shaft sidewalls. The three building bodies 2 correspond to the three shaft sidewalls of the exhaust shaft 1 respectively. The exhaust pipes 4 of the three building bodies 2 pass through their corresponding shaft sidewalls to connect the exhaust end of the cold source equipment 3 with the exhaust shaft 1, so that the hot air of the three building bodies 2 is discharged through one exhaust shaft 1.

[0103] As an example, such as Figure 9 As shown, there are four building bodies 2. The four building bodies 2 are evenly arranged in a circle along the center line of the exhaust shaft 1. The cross-section of the exhaust shaft 1 is square, that is, the exhaust shaft 1 has four shaft side walls. The four building bodies 2 correspond to the four shaft side walls of the exhaust shaft 1 respectively. The exhaust pipes 4 of the four building bodies 2 pass through their corresponding shaft side walls to connect the exhaust end of the cold source equipment 3 with the exhaust shaft 1, so that the hot air of the four building bodies 2 can be discharged through one exhaust shaft 1.

[0104] As an example, such as Figure 10 As shown, there are five building bodies 2. The five building bodies 2 are evenly arranged in a circle along the center line of the exhaust shaft 1. The cross-section of the exhaust shaft 1 is a regular pentagon, that is, the exhaust shaft 1 has five shaft sidewalls. The five building bodies 2 correspond to the five shaft sidewalls of the exhaust shaft 1 respectively. The exhaust pipes 4 of the five building bodies 2 pass through their corresponding shaft sidewalls to connect the exhaust end of the cold source equipment 3 to the exhaust shaft 1, so that the hot air discharged by the multiple cold source equipment 3 of the five building bodies 2 can be discharged through one exhaust shaft 1.

[0105] It is understood that the building body 2 of the data center heat exchange system in this embodiment of the invention can be arranged in a suitable manner according to the construction site, construction requirements, etc., which will not be elaborated here.

[0106] In some embodiments, the building 2 includes at least four building layers 21 arranged sequentially in the vertical direction.

[0107] By setting up a multi-story building 21, land utilization can be improved. With the same land area, the building 2 of the data center heat exchange system can accommodate more computer rooms.

[0108] As an example, such as Figure 7 As shown, there are three heat exchange system groups, which are arranged in sequence. The building 2 of each heat exchange system group has ten floors. The first floor is for auxiliary rooms, and the second to tenth floors are machine room floors. The number of machine room floors is fifty-four, which can greatly improve the land utilization rate.

[0109] As an example, there are five building bodies 2, which are evenly arranged in a circle along the center line of the ventilation shaft 1, and the five building bodies 2 share one ventilation shaft 1. Figure 11 This is an axonometric view of a simulation diagram of the air intake and exhaust of five buildings 2 sharing a single exhaust shaft 1 in an embodiment of the present invention. Figure 12 This is a top view of a simulation diagram of the air intake and exhaust of five buildings 2 sharing a single exhaust shaft 1 in an embodiment of the present invention. Figure 13 This is a simulation diagram of the air intake and exhaust of one of the five buildings 2 sharing a single exhaust shaft 1 in an embodiment of the present invention. Figures 11 to 13 The left side of the screen displays temperature color codes, which represent the numerical values ​​of temperatures from low to high from bottom to top. To make it easier to distinguish, different temperature ranges are represented by different colors, such as blue, green, yellow, and red, representing temperatures from low to high in that order.

[0110] like Figure 11 As shown, the high-temperature exhaust airflow discharged from multiple cold source devices 3 of each building 2 gathers towards the central area in the exhaust shaft 1 (shown in red in the figure). As the high-temperature exhaust airflow is discharged upward in the exhaust shaft 1, its temperature gradually decreases (shown in the figure as gradually changing from red to yellow and then green). After being discharged through the exhaust port 11 at the top of the exhaust shaft 1, it diffuses upward. The airflow of the cold source devices 3 is distributed on the side of the exhaust shaft 1 (shown in blue in the figure).

[0111] like Figure 12As shown in the figure, the airflow shown is the sum of the airflow of all the building floors 21 of the five buildings 2. The red part at the connection between the exhaust shaft 1 and the machine room in the figure represents the high-temperature exhaust airflow in the exhaust pipe 4. The high-temperature exhaust airflow discharged by the multiple cold source equipment 3 of each building 2 enters the exhaust shaft 1 through the exhaust pipe 4 and gathers in the central area of ​​the exhaust shaft 1 (shown in red in the figure). In order to facilitate the display of airflow, the top enclosure structure 5 is hidden in the figure.

[0112] like Figure 13 As shown in the figure, the airflow shown is the sum of the airflow of all the building floors 21 of one of the buildings 2. The red part at the connection between the exhaust shaft 1 and the machine room in the figure represents the high-temperature exhaust airflow in the exhaust pipe 4. For a single building 2, its intake airflow (shown as blue in the figure) and exhaust airflow (shown as red and yellow in the figure) are completely separated and do not interfere with each other. To facilitate the display of airflow, the top enclosure structure 5 is hidden in the figure.

[0113] Therefore, it can be seen that the intake and exhaust airflows of this data center heat exchange system are completely separated and do not interfere with each other. This prevents the intake airflow of the cold source equipment 3 from being affected by the exhaust airflow, and prevents the temperature of the intake airflow of the cold source equipment 3 from rising due to the mixing of the intake and exhaust airflows, thereby improving the cooling capacity of the cold source equipment 3 and reducing energy consumption. At the same time, it is more conducive to the independent design of the exhaust shaft 1 and the intake area, and can simultaneously meet the design requirements of the number of building floors 21, the number of cold source equipment 3 installed on a single building floor 21, and the airflow of the near-end cold source equipment 3.

[0114] The data center heat exchange system of this invention has the following effects: The exhaust shaft 1 of this invention can be designed in different sizes according to the different heights of the building floor 21. At the same time, the air inlet chamber 27 can be designed in different sizes according to the different number of units and air volume in a single building floor 21, so as to meet the higher requirements of the number of building floors 21, the number of computer rooms, the number of IT cabinets 2111, and the capacity of a single cabinet in a single building 2. It can also meet the higher requirements of the single unit cooling capacity and air volume of the cold source equipment 3 product design.

[0115] Compared with the exhaust method through a separate air duct in related technologies, the data center heat exchange system of this invention can directly discharge the exhaust airflow to the top of the data center through the exhaust port 11 of the exhaust shaft 1, reducing the air supply and exhaust resistance, and at the same time reducing the fan energy consumption of the cold source equipment 3, thereby achieving energy saving in the data center.

[0116] The data center heat exchange system of this invention, based on the near-end cooling unit in related technologies, can reduce the air resistance of the supply and exhaust air, thereby increasing the number of building floors in the data center and improving land utilization.

[0117] Compared with one to four-story buildings in related technologies, the data center heat exchange system of this invention can increase the number of floors of the building 2 and the number of IT cabinets 2111, making full use of the land resources of the data center park, achieving high energy efficiency of the data center, and improving the IT power output of the data center park.
