Description

Technical Field

[0001] This application relates to the field of liquid cooling technology, and in particular to a liquid cooling device. Background Technology

[0002] The explosion of artificial intelligence has led to a surge in demand for intelligent computing servers. To enable a single server to provide higher computing power, multiple GPUs and CPU chips are typically placed inside, resulting in extremely high power consumption. To address the server heat dissipation issue, liquid cooling is currently used to ensure the server can operate normally.

[0003] Liquid-liquid heat exchangers are frequently used in medium to large-scale data centers due to their high heat exchange efficiency, large heat capacity, and high energy utilization efficiency. However, when arranging the pipes and related structural components connected to the heat exchanger, the limited internal space of the equipment makes it impossible to simultaneously ensure a reasonable pipe layout and functional integrity, thus affecting heat exchange efficiency and ease of operation and maintenance. Utility Model Content

Detailed Implementation

[0071] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0072] To address the issues of limited internal space affecting heat exchange efficiency and inconvenient operation and maintenance in existing liquid-liquid heat exchange devices, embodiments of this application provide a liquid cooling device and a liquid cooling heat exchange system to improve heat exchange efficiency and ease of operation and maintenance.

[0073] refer to Figure 1The liquid cooling heat exchange system in this application embodiment may include a liquid cooling device 1, a primary side pump group 20 and a cold source device 30. The liquid cooling device 1 may include a chassis 100 and a heat exchanger 10 disposed inside the chassis 100, a secondary side pump group 40, a primary side liquid inlet pipe 60, a primary side liquid outlet pipe 70, a secondary side liquid inlet pipe 80 and a secondary side liquid outlet pipe 90.

[0074] The cooling source unit 30 and the primary side pump assembly 20 are located outside the chassis 100. One end of the primary side inlet pipe 60 is connected to the heat exchanger 10, and the other end can be connected to the cooling source unit 30 via a pipe. One end of the primary side outlet pipe 60 is connected to the heat exchanger 10, and the other end can be connected to the cooling source unit 30 via a pipe. The primary side pump assembly 20 is connected to either the primary side inlet pipe 60 or the primary side outlet pipe 70.

[0075] One end of the secondary side inlet pipe 80 is connected to the heat exchanger 10, and the other end can be connected to the cooling device 1000 via a pipe. One end of the secondary side inlet pipe 90 is connected to the heat exchanger 10, and the other end can be connected to the cooling device 1000 via a pipe. The secondary side pump unit 40 is installed on either the secondary side inlet pipe 80 or the secondary side outlet pipe 90.

[0076] Here, the inlet pipe can be understood as the pipe through which liquid flows to the heat exchanger 10, and the outlet pipe can be understood as the pipe through which liquid flows out of the heat exchanger 10. Additionally, the heat exchanger 10 can be connected to a cooling device 1000, which can be a liquid-cooled server, an immersion liquid-cooled cabinet, a cold-plate liquid-cooled device, or a liquid-cooled data center. When coolant can circulate inside the liquid-cooled server, the heat exchanger 10 can be directly connected to the liquid-cooled server, allowing the coolant to circulate inside the server and directly exchange heat with the components inside. When the cooling device 1000 is an immersion liquid-cooled cabinet, the coolant circulates between the cabinet and the heat exchanger 10, allowing the coolant to exchange heat with the liquid-cooled server placed inside the cabinet. When the cooling device 1000 is a cold-plate liquid-cooled device, the cold plate or liquid-cooling device can be thermally connected to the liquid-cooled server to exchange heat with it.

[0077] In this embodiment, during operation of the liquid cooling heat exchange system, driven by the secondary-side pump group 40, the coolant in the cooling device 1000, which is used to exchange heat with electronic components such as chips and raise their temperature, flows into the heat exchanger 10 through the secondary-side inlet pipe 80 and exchanges heat with the cold source in the heat exchanger 10. The cooled liquid then flows back to the cooling device 1000 through the secondary-side outlet pipe 90. During this process, driven by the primary-side pump group 20, the low-temperature cold source in the cold source device 30 enters the heat exchanger 10 through the primary-side inlet pipe 60, and the high-temperature cold source in the heat exchanger 10, after heat exchange, flows back to the cold source device 30 through the primary-side outlet pipe 70. Thus, with the cooperation of the above-mentioned components, the cooling device 1000 can achieve uninterrupted heat dissipation.

[0078] Please refer to the above. Figures 1 to 5 The chassis 100 may include a top plate 101 and a bottom plate 102 arranged opposite to each other, a front maintenance door 103 and a rear maintenance door 104 arranged opposite to each other, and a left door 105 and a right door 106 arranged opposite to each other. The front maintenance door 103, the rear maintenance door 104, the left door 105 and the right door 106 are respectively connected between the top plate 101 and the bottom plate 102. Furthermore, the front maintenance door 103, the left door 105, the rear maintenance door 104 and the right door 106 are connected end to end in sequence to form a chassis 100 with a square structure.

[0079] The front maintenance door 103 and the rear maintenance door 104 can rotate relative to the top plate 101 to be in an open or closed state. When the system is running normally, both the front maintenance door 103 and the rear maintenance door 104 are closed. When maintenance is required, the front maintenance door 103 and / or the rear maintenance door 104 can be opened to facilitate maintenance by the operators.

[0080] For ease of description, in the following embodiments, the arrangement direction of the front maintenance door panel 103 and the rear maintenance door panel 104 is set as the x-direction, the arrangement direction of the left door panel 105 and the right door panel 106 is set as the y-direction, and the arrangement direction of the top panel 101 and the bottom panel 102 is set as the z-direction.

[0081] One of the heat exchanger 10 and the secondary pump assembly 40 is located near the top plate 101, and the other is located on the bottom plate 102. That is, when the heat exchanger 10 is located near the top plate 101, the secondary pump assembly 40 is located on the bottom plate 102. When the secondary pump assembly 40 is located near the top plate 101, the heat exchanger 10 is located on the bottom plate 102.

[0082] In practical applications, for ease of maintenance, combined with Figure 2 and Figure 4The heat exchanger 10 can be positioned near the top plate 101, and the secondary pump unit 40 can be positioned on the bottom plate 102. This makes it easier for operators to remove the heat exchanger 10 from the casing 100 when maintenance or replacement is required.

[0083] Continue to refer to Figures 1 to 5 The liquid-cooled heat exchange system in this embodiment may further include a distribution box 250 disposed within the chassis 100. The distribution box 250 is located near the top plate 101, and the distribution box 250 and the heat exchanger 10 are arranged along the x-direction. That is, one of the distribution box 250 and the heat exchanger 10 is arranged near the front maintenance door 103, and the other is arranged near the rear maintenance door 104. Specifically, the distribution box 250 may be near the front maintenance door 103, and the heat exchanger 10 may be near the rear maintenance door 104. When it is necessary to maintain the distribution box 250, the front maintenance door 103 can be opened, and when it is necessary to maintain the heat exchanger 10, the rear maintenance door 104 can be opened. In addition, in the x-direction, the primary side liquid inlet pipe 60, the primary side liquid outlet pipe 70, the secondary side liquid inlet pipe 80, and the secondary side liquid outlet pipe 90 can all be installed on the side of the distribution box 250 facing the heat exchanger 10. In this way, the space inside the chassis 100 can be divided in the x-direction into the front power distribution control area and the rear equipment pipeline heat exchange area, thereby achieving water and electricity separation and ensuring the safety of operators.

[0084] The first end of each of the primary side inlet pipe 60, primary side outlet pipe 70, secondary side inlet pipe 80, and secondary side outlet pipe 90 can be connected to the bottom of the heat exchanger 10, and the other end can be connected to the secondary side pump group 40 or a pipe outside the casing 100. In this embodiment, at least a portion of each inlet or outlet pipe inside the casing 100 can extend along the z-direction to the top plate 101 or the bottom plate 102. The top plate 101 or the bottom plate 102 can be provided with through holes so that the inlet or outlet pipes can pass through the through holes and then connect to the external pipes.

[0085] It is understood that in this embodiment, since the heat exchanger 10 and the secondary pump group 40 are respectively located at the upper and lower parts of the chassis 100, the heat exchanger 10 and the secondary pump group 40 are physically far apart. When the heat exchanger 10 and the secondary pump group 40 are connected by pipelines, the pipeline distance between the heat exchanger 10 and the secondary pump group 40 can be lengthened. In this way, the pipeline between the heat exchanger 10 and the secondary pump group 40 can be connected sequentially using multiple straight pipeline segments, making the entire pipeline connection smooth, thereby reducing the resistance in the circulation process and achieving energy saving. Due to the long pipeline distance, the pipeline has sufficient space to arrange structural components such as sensors, so as to improve the automatic adjustment capability of the entire system and thus improve the heat dissipation efficiency. Furthermore, since the heat exchanger 10 and the secondary pump group 40 are far apart, each has sufficient expansion space. Without affecting the overall structural design, the heat exchanger 10 and the secondary pump group 40 can be designed separately according to the actual heat dissipation requirements to improve the heat dissipation efficiency of the system. That is, the expansion capacity of the internal design of the chassis 100 in this embodiment is very good.

[0086] Taking the heat exchanger 10 in this embodiment as a plate heat exchanger as an example, combined with Figure 4 and Figure 8 , Figure 8 The dotted line area can be understood as the expanded portion of the heat exchanger 10 and the expanded portion of the secondary-side pump group 40. When it is necessary to enhance the heat exchange capacity of the heat exchanger 10, this can be achieved by increasing the number of plates or increasing the size and area of ​​the plates. In this case, the area of ​​the heat exchanger 10 in contact with the coolant increases, thereby enhancing the heat exchange capacity. For the secondary-side pump group 40, when it is necessary to improve the heat dissipation capacity, this can be achieved by selecting a pump group with a larger power or by increasing the number of pump groups. When increasing the number of pump groups, multiple pump groups can be arranged, for example, along the y-direction. At this time, branch pipes can be set to connect to each pump group respectively, and each branch pipe is connected to the secondary-side liquid inlet pipe 80 or the secondary-side liquid outlet pipe 90 connected to the secondary-side pump group 40, thereby achieving the effect of multiple pump groups in parallel. Thus, in this embodiment, by setting the heat exchanger 10 and the secondary-side pump group 40 above and below the chassis 100 respectively, more sizes of heat exchangers 10 and secondary-side pump groups 40 can be adapted to meet different equipment power and cooling capacity requirements, and the heat dissipation efficiency can be improved more effectively.

[0087] It is worth mentioning that, such as Figure 6 As shown, when the heat exchanger 10 is positioned near the top plate 101, the inlet and outlet pipes within the casing 100 can extend to the bottom plate 102. This increases the length of the pipes within the casing 100, allowing for the arrangement of more structural components along the pipes. Of course, under these conditions, such as... Figure 7As shown, if one or two pipes do not have structural components or have few structural components, the pipe can also be extended to the top plate 101 to facilitate connection with pipes outside the chassis 100.

[0088] In some embodiments, for the convenience of arranging the various pipes within the chassis 100, refer again to Figure 4 and Figure 5 In the y-direction, a portion of the primary side liquid inlet pipe 60, the primary side liquid outlet pipe 70, the secondary side liquid inlet pipe 80, and the secondary side liquid outlet pipe 90 can be located near the left door panel 105, and another portion can be located near the right door panel 106, so that in the y-direction, the space between the heat exchanger 10 and the secondary side pump group 40 retains an operable space, so that operators can operate and maintain within this space.

[0089] As an optional implementation, the primary side liquid inlet pipe 60 and the primary side liquid outlet pipe 70 are respectively located near the left door panel 105 and the right door panel 106, and the secondary side liquid inlet pipe 80 and the secondary side liquid outlet pipe 90 are respectively located near the left door panel 105 and the right door panel 106, that is, two pipes are respectively provided on the left and right sides.

[0090] To further optimize the pipeline layout, such as Figure 4 or Figure 5 As shown, in the x-direction, the secondary pump unit 40 and the heat exchanger 10 can be located in the space inside the chassis 100 near the rear maintenance door 104. Each inlet pipe and each outlet pipe includes at least a first segment a extending in the z-direction, a second segment b extending in the x-direction, and a third segment c extending in the z-direction. The first segment a, the second segment b, and the third segment c of each pipe are connected sequentially. The first segment a is connected to the heat exchanger 10, and the third segment c is the portion of the second segment b extending in the z-direction of each pipe to the base plate 102. In practical applications, the length of the third segment c can be greater than the length of the first segment a, that is, the second segment b is closer to the heat exchanger 10 in the z-direction.

[0091] Taking the secondary side pump assembly 40 connected to the secondary side outlet pipeline 90 as an example, the secondary side outlet pipeline 90 may also include a transition section, which connects the second section b and the third section c, so that the third section c of the secondary side outlet pipeline 90 can be located at the point of connection with the secondary side pump assembly 40. Figures 2 to 5As shown, there is a certain space between the secondary pump assembly 40 and the rear maintenance door 104 in the x direction. The second section b of the primary inlet pipe 60, the primary outlet pipe 70, and the secondary inlet pipe 80 all extend in the x direction so that the third section c of the primary inlet pipe 60, the primary outlet pipe 70, and the secondary inlet pipe 80 are all located on the side of the secondary pump assembly 40 facing the rear maintenance door 104. This can avoid interference between the pipes and the secondary pump assembly 40.

[0092] Furthermore, to facilitate the arrangement of sensors and other structural components on each pipeline, the second segment b of the two pipelines closest to the left door panel 105 or the right door panel 106 can maintain a certain distance in the y-direction or z-direction, and the third segment c of the two pipelines closest to the left door panel 105 or the right door panel 106 can also maintain a certain distance in the x-direction.

[0093] In some embodiments, refer again Figure 2 and Figure 3 The left door panel 105 may include at least two left side panels 1051, which are arranged along the direction of the top panel 101 and the bottom panel 102. Each left side panel 1051 is detachably connected to the front maintenance door panel 103 and the rear maintenance door panel 104. Similarly, the right door panel 106 may include at least two right side panels 1061, which are arranged along the direction of the top panel 101 and the bottom panel 102. Each right side panel 1061 is detachably connected to the front maintenance door panel 103 and the rear maintenance door panel 104. When maintenance or replacement of a portion of the structural components is required, a portion of the left side panel 1051 or right side panel 1061 can be detached, facilitating operation by personnel.

[0094] When the chassis 100 is placed on the ground and operating normally, the front maintenance door 103 can be considered as the front side door, and the rear maintenance door 104 can be considered as the rear side door. At this time, the front maintenance door 103 may also be equipped with a human-machine interface touchscreen 107 and / or operating status indicator lights 108 and / or ventilation holes 109. Operators can use the operating status indicator lights 108 to understand whether the chassis 100 is in normal operation or a faulty state. Operators can also operate on the human-machine interface touchscreen 107 to facilitate parameter settings and other operations. The ventilation holes 109 are used for heat dissipation; the heat generated inside the chassis 100 during operation can be dissipated through the ventilation holes 109 to ensure that the inside of the chassis 100 does not overheat.

[0095] The aforementioned human-machine interface touch screen 107, running status indicator 108, and ventilation hole 109 can be selected as one, two, or all of them. In specific arrangements, the human-machine interface touch screen 107 and running status indicator 108 can be located near the top plate 101, and the ventilation hole 109 can be located near the bottom plate 102.

[0096] The rear maintenance door panel 104 may also be provided with ventilation holes 109 to cooperate with the ventilation holes 109 on the front maintenance door panel 103, thereby improving the heat dissipation efficiency inside the chassis 100. In this case, the rear maintenance door panel 104 may be provided with ventilation holes 109 near the top plate 101 and the bottom plate 102, respectively. As mentioned above, the heat exchanger 10 and the electrical distribution box 250 are located near the top plate 101, and the secondary side pump group 40 is located on the bottom plate 102. When the chassis 100 is running, the heat generated inside the chassis 100 is mainly concentrated at the top and bottom. By providing ventilation holes 109, the heat inside the chassis 100 can be dissipated more efficiently.

[0097] In some embodiments, reference is also made to Figure 1 , Figure 4 , Figures 9 to 10 The liquid-cooled heat exchange system may also include a primary-side filter device 110, which is located inside the chassis 100 and installed in the primary-side liquid inlet pipe 60. It can be understood that the cold source in the cold source device 30 can be filtered by the primary-side filter device 110 before entering the heat exchanger 10, preventing impurities in the cold source from entering the heat exchanger 10 and causing blockage inside the heat exchanger 10, thus affecting the heat exchange efficiency of the cold source device 30 to the heat exchanger 10.

[0098] Specifically, the primary-side filtration device 110 is disposed in the second section b of the primary-side liquid inlet pipe 60. The primary-side filtration device 110 includes a first housing 111, a first filter element 112, and a first cover plate 113. The first housing 111 extends along the x-direction and is provided with a first liquid inlet 115, a first liquid outlet 116, and a first opening 117. The axial direction of the first liquid inlet 115 is parallel to the z-direction, and the first liquid outlet 116 and the first opening 117 are disposed at both ends of the first housing 111 along the x-direction, that is, the axial direction of the first liquid outlet 116 is parallel to the x-direction. In addition, the first liquid inlet 115 is connected to the third section c of the primary-side liquid inlet pipe 60, and the first liquid outlet 116 is connected to the first section a of the primary-side liquid inlet pipe 60.

[0099] The first filter element 112 can extend into the interior of the first housing 111 through the first opening 117. The first cover plate 113 is fixedly connected to the side of the first filter element 112 away from the first liquid outlet 116, and the first cover plate 113 is used to cover the first opening 117. Furthermore, the first cover plate 113 can be fixed to the first housing 111 through the first locking structure 114 to ensure that the first filter element 112 can remain relatively fixed to the first housing 111 during use. The first cover plate 113 and the first housing 111 can be detachably connected through the first locking structure 114 to facilitate the replacement of the first filter element 112 and ensure the filtration capacity of the primary side filtration device 110.

[0100] In this embodiment, when the cold source flows in the primary side inlet pipe 60, the cold source enters the first housing 111 through the first inlet 115, is filtered by the first filter element 112, and then leaves the first housing 111 through the first outlet 116, and then enters the heat exchanger 10. At this time, the primary side filter device 110 can not only act as a filter, but also as a pipe bend, thereby connecting the first section a and the third section c of the primary side inlet pipe 60, solving the pipe bend requirement.

[0101] Combination Figure 2 , Figure 4 , Figures 9 to 11 As shown, the first cover plate 113 is located on the side near the rear maintenance door panel 104. When the first filter element 112 needs to be replaced, the operator can open the rear maintenance door panel 104, unlock the first locking structure 114, and then pull the first filter element 112 out of the first housing 111. During this process, the operator only needs to stand on one side of the rear maintenance door panel 104 to complete the replacement of the first filter element 112, which greatly improves the convenience of operation.

[0102] Continue to refer to Figure 1 , Figures 4 to 5 as well as Figures 9 to 10 The primary-side filtration device 110 may further include a primary-side filtration bypass circuit 118. The passage between the first liquid inlet 115 and the first liquid outlet 116 is connected in parallel with the primary-side filtration bypass circuit 118. That is, one end of the primary-side filtration bypass circuit 118 is connected to the first section a of the primary-side liquid inlet pipe 60, and the other end is connected to the third section c of the primary-side liquid inlet pipe 60. At this time, the cold source in the third section c of the primary-side liquid inlet pipe 60 can enter the heat exchanger 10 after passing through the first filter element 112, or it can enter the heat exchanger 10 through the primary-side filtration bypass circuit 118 without passing through the first filter element 112.

[0103] Based on this, primary side filter regulating valves 119 can be respectively installed in the first liquid inlet 115, the first liquid outlet 116 and the primary side filter bypass circuit 118 to control the cold source flow of each part.

[0104] When the system is operating normally, the primary-side filter regulating valve 119 of the first inlet 115 and the first outlet 116 is open, and the primary-side filter regulating valve 119 in the primary-side filter bypass circuit 118 is closed. The cold source enters the heat exchanger 10 after being filtered by the first filter element 112. When the first filter element 112 needs to be replaced, the primary-side filter regulating valve 119 of the first inlet 115 and the first outlet 116 can be closed, and the primary-side filter regulating valve 119 in the primary-side filter bypass circuit 118 can be opened. At this time, the cold source device 30 can still exchange heat with the heat exchanger 10. It can be understood that by setting the primary-side filter bypass circuit 118, the online non-stop cleaning and maintenance of the filtration equipment can be achieved, which is conducive to ensuring the heat dissipation efficiency of the system.

[0105] Continue to refer to Figure 1 , Figures 4 to 5 The liquid-cooled heat exchange system in this embodiment may further include a primary-side bypass pipe 120 and a primary-side bypass valve 130 disposed within the chassis 100. One end of the primary-side bypass pipe 120 is connected to the third segment c of the primary-side inlet pipe 60, and the other end is connected to the third segment c of the primary-side outlet pipe 70. The primary-side bypass pipe 120 is positioned close to the base plate 102. The primary-side bypass valve 130 is disposed on the primary-side bypass pipe 120 to regulate the flow rate within the primary-side bypass pipe 120. In this case, in the x-direction, the primary-side bypass valve 130 is located on the base plate 102 away from the secondary-side pump assembly 40.

[0106] It is understandable that, on the one hand, by setting up a primary bypass pipe 120 in this embodiment, when the number of cooling devices 1000, such as liquid-cooled servers, in the system is small, the heat exchange between the heat exchanger 10 and the cooling devices 1000 is small, resulting in a reduction in the heat exchange between the cold source device 30 and the heat exchanger 10. Since the power of the primary side pump group 20 is constant, in this situation, the primary side bypass valve 130 can be opened, and by adjusting the opening degree of the primary side bypass valve 130, a portion of the cold source can directly return to the cold source device 30 through the primary side bypass pipe 120, thereby maintaining the pressure change of the terminal cooling device 1000. Conversely, when the number of cooling devices 1000, such as liquid-cooled servers, is large, the primary side bypass valve 130 can be closed.

[0107] On the other hand, the primary bypass pipe 120 is located on the side of the primary filter device 110 away from the heat exchanger 10. During the initial system installation, all primary filter regulating valves 119 in the primary filter device 110 can be closed, and the primary bypass valve 130 can be opened. At this time, all the cold source in the cold source device 30 returns to the cold source device 30 through the primary bypass pipe 120. During this process, the primary bypass pipe 120 is used as a bypass pipe for circulation flushing, preventing the cold source in the cold source device 30 from directly contaminating the heat exchanger 10 and the pipes. After flushing, the primary bypass valve 130 can be closed, and the primary filter regulating valves 119 at the first inlet 115 and the first outlet 116 can be opened, allowing the system to operate normally.

[0108] In some embodiments, reference is also made to Figure 1 , Figures 4 to 5 , Figures 12 to 13 The liquid-cooled heat exchange system may also include a secondary-side filter 180 installed inside the chassis 100, which is located in the secondary-side liquid outlet pipe 90. When the coolant flows back from the heat exchanger 10 to the cooling device 1000, the secondary-side filter 180 filters the coolant to prevent impurities in the coolant from entering the cooling device 1000 and thus affecting the heat dissipation performance of the cooling device 1000.

[0109] In this embodiment, the secondary side filtration device 180 can be disposed in the second section b of the secondary side liquid outlet pipeline 90. The secondary side filtration device 180 includes a second housing 181, a second filter element 182, and a second cover plate 183. The second housing 181 extends along the x-direction and is provided with a second inlet 185, a second outlet 186, and a second opening 187. The axial direction of the second inlet 185 is parallel to the x-direction, and the second inlet 185 and the second opening 187 are disposed at both ends of the second housing 181 along the x-direction, that is, the axial direction of the second inlet 185 is parallel to the x-direction. In addition, the second inlet 185 is connected to the first section a of the secondary side liquid outlet pipeline 90, and the second outlet 186 is connected to the third section c of the secondary side liquid inlet pipeline 80.

[0110] The second filter element 182 can extend into the interior of the second housing 180 through the second opening 187. The second cover plate 183 is fixedly connected to the side of the second filter element 182 away from the second liquid inlet 185, and the second cover plate 183 is used to cover the second opening 187. Furthermore, the second cover plate 183 can be fixed to the second housing 181 through the second locking structure 184 to ensure that the second filter element 182 can remain relatively fixed to the second housing 181 during use. The second cover plate 183 and the second housing 181 can also be detachably connected through the second locking structure 184 to facilitate the replacement of the second filter element 182 and ensure the filtration capacity of the secondary side filtration device 180.

[0111] In this embodiment, when the coolant flows in the secondary side outlet pipe 90, the coolant enters the second housing 181 through the second inlet 185, is filtered by the second filter element 182, and then leaves the second housing 181 through the second outlet 186, thus entering the cooling device 1000. At this time, the secondary side filter device 180 can not only act as a filter, but also as a pipe bend, thereby connecting the first section a and the third section c of the secondary side outlet pipe 90, solving the pipe bend requirement.

[0112] When maintaining the secondary side filter device 180, the operation is the same as that for maintaining the primary side filter device 110, and will not be described again here.

[0113] Continue to refer to Figure 1 , Figures 4 to 5 , Figures 12 to 13 The secondary side filtration device 180 may further include a secondary side filtration bypass circuit 188. The passage between the second inlet 185 and the second outlet 186 is connected in parallel with the secondary side filtration bypass circuit 188. That is, one end of the secondary side filtration bypass circuit 188 is connected to the first section a of the secondary side outlet pipe 90, and the other end is connected to the third section c of the secondary side outlet pipe 90. In this case, the coolant in the secondary side inlet and outlet pipes can either pass through the second filter element 182 before entering the cooling device 1000, or it can bypass the second filter element 182 and enter the cooling device 1000 through the secondary side filtration bypass circuit 188.

[0114] Based on this, secondary side filter regulating valves 189 can be respectively installed in the second liquid inlet 185, the second liquid outlet 186 and the secondary side filter bypass circuit 188 to control the coolant flow rate of each part.

[0115] When the system is operating normally, the secondary side filtration regulating valve 189 of the second inlet 185 and the second outlet 186 is open, while the secondary side filtration regulating valve 189 in the secondary side filtration bypass circuit 188 is closed. The coolant enters the cooling device 1000 after being filtered by the second filter element 182. When the second filter element 182 needs to be replaced, the secondary side filtration regulating valve 189 of the second inlet 185 and the second outlet 186 can be closed, while the secondary side filtration regulating valve 189 in the secondary side filtration bypass circuit 188 can be opened. At this time, the cooling device 1000 can still exchange heat with the heat exchanger 10. It can be understood that by setting the secondary side filtration bypass circuit 188, the filtration equipment can be cleaned and maintained online without stopping, which helps to ensure the heat dissipation efficiency of the system.

[0116] Refer again Figure 1 , Figures 4 to 5 The liquid-cooled heat exchange system in this embodiment may further include a secondary-side bypass pipe 190 and a secondary-side bypass valve 200 disposed within the chassis 100. One end of the secondary-side bypass pipe 190 is connected to the third section c of the secondary-side liquid inlet pipe 80, and the other end is connected to the third section c of the secondary-side liquid outlet pipe 90. Furthermore, in the x-direction, the secondary-side bypass pipe 190 may be disposed close to the secondary-side pump group 40. The secondary-side bypass valve 200 is disposed on the secondary-side bypass pipe 190 for regulating the flow rate in the secondary-side bypass pipe 190.

[0117] In this embodiment, when the number of cooling devices 1000, such as liquid-cooled servers, is small, the secondary bypass valve 200 can be opened, and by adjusting the opening degree of the secondary bypass valve 200, a portion of the coolant can directly return to the cooling device 1000 through the secondary bypass pipe 190, thereby maintaining the pressure variation of the cooling device 1000. When the number of cooling devices 1000, such as liquid-cooled servers, is large, the secondary bypass valve 200 can be closed. Furthermore, it is worth mentioning that the secondary bypass pipe 190 is located on the side of the secondary filter device 180 away from the heat exchanger 10, so the coolant entering the secondary bypass pipe 190 will not pass through the secondary filter device 180, thus reducing the filtration pressure of the secondary filter device 180.

[0118] In some embodiments, reference is also made to Figure 1 , Figures 4 to 5The liquid-cooled heat exchange system may also include a primary-side temperature sensor 140, a primary-side pressure sensor 150, a primary-side flow sensor 160, and a primary-side regulating valve 170, all disposed within the chassis 100. Specifically, the primary-side temperature sensor 140 is disposed on the primary-side inlet pipe 60 and / or the primary-side outlet pipe 70; the primary-side pressure sensor 150 is disposed on the primary-side inlet pipe 60 and / or the primary-side outlet pipe 70; the primary-side flow sensor 160 is disposed on either the primary-side inlet pipe 60 or the primary-side outlet pipe 70; and the primary-side regulating valve 170 is disposed on either the primary-side inlet pipe 60 or the primary-side outlet pipe 70.

[0119] For example, at least two primary-side temperature sensors 140 and primary-side pressure sensors 150 can be provided respectively. This allows for more accurate detection of the temperature and pressure of the primary-side circulation pipeline, which in turn enables precise adjustment of the parameters of the primary-side circulation pipeline to ensure heat dissipation efficiency.

[0120] The primary-side flow sensor 160 can be used to detect the cold source flow rate in the primary-side circulation pipeline. The primary-side regulating valve 170 can adjust its opening degree according to the detection result of the primary-side flow sensor 160 to regulate the cold source flow rate in the primary-side circulation pipeline. Of course, the primary-side regulating valve 170 can also adjust its opening degree in combination with the detection results of the primary-side flow sensor 160, the primary-side temperature sensor 140, and the primary-side pressure sensor 150 to regulate the cold source flow rate in the primary-side circulation pipeline.

[0121] Specifically, when arranging the sensors on the primary side, the primary side temperature sensor 140 can be arranged in the middle of the first section a and / or the third section c of the primary side inlet pipe 60 and / or the first section a and / or the third section c of the primary side outlet pipe 70. The primary side pressure sensor 150 can be arranged in the middle of the first section a and / or the third section c of the primary side inlet pipe 60 and / or the first section a and / or the third section c of the primary side outlet pipe 70.

[0122] When at least two primary-side temperature sensors 140 and at least two primary-side pressure sensors 150 are provided, for example, some of the primary-side temperature sensors 140 and some of the primary-side pressure sensors 150 can be arranged in the first section a of the primary-side liquid inlet pipe 60, and the other part of the primary-side temperature sensors 140 and the other part of the primary-side pressure sensors 150 can be arranged in the middle of the third section c of the primary-side liquid outlet pipe 70. In this way, the sensors are spatially staggered to avoid mutual interference.

[0123] The primary flow sensor 160 can be installed in the middle of the third section c of the primary inlet pipe 60, or in the middle of the third section c of the primary outlet pipe 70.

[0124] The primary side regulating valve 170 can be installed in the third section c of the primary side inlet pipe 60 near the bottom plate 102, or in the third section c of the primary side outlet pipe 70 near the bottom plate 102.

[0125] In some embodiments, continue to refer to Figure 1 , Figures 4 to 5 The liquid-cooled heat exchange system may also include a secondary-side temperature sensor 210, a secondary-side pressure sensor 220, a secondary-side flow sensor 230, and a secondary-side regulating valve (not shown in the figure) disposed within the chassis 100. The secondary-side temperature sensor 210 and the secondary-side pressure sensor 220 are disposed on the secondary-side inlet pipe 80 and / or the secondary-side outlet pipe 90, the secondary-side flow sensor 230 is disposed on either the secondary-side inlet pipe 80 or the secondary-side outlet pipe 90, and the secondary-side regulating valve is disposed on either the secondary-side inlet pipe 80 or the secondary-side outlet pipe 90.

[0126] For example, two sets of secondary-side temperature sensors 210 and secondary-side pressure sensors 220 can be provided, one set being provided in the secondary-side inlet pipe 80 and the other set being provided in the secondary-side outlet pipe 90. In this way, the temperature and pressure of the secondary-side circulation pipe can be detected more accurately, thereby allowing for precise adjustment of the parameters of the secondary-side circulation pipe to ensure heat dissipation efficiency.

[0127] The secondary-side flow sensor 230 can be used to detect the cold source flow rate in the secondary-side circulation pipeline. The secondary-side regulating valve can adjust its opening degree according to the detection result of the secondary-side flow sensor 230 to regulate the cold source flow rate in the secondary-side circulation pipeline. Of course, the secondary-side regulating valve can also adjust its opening degree in combination with the detection results of the secondary-side flow sensor 230, the secondary-side temperature sensor 210, and the secondary-side pressure sensor 220 to regulate the cold source flow rate in the secondary-side circulation pipeline.

[0128] Specifically, when arranging the sensors on the secondary side, the secondary side temperature sensor 210 and the secondary side pressure sensor 220 can be arranged in the middle of the first section a or the third section c of the secondary side inlet pipe 80, or they can be arranged in the middle of the first section a or the third section c of the secondary side outlet pipe 90. When two sets of secondary side temperature sensors 210 and secondary side pressure sensors 220 are provided, for example, one set can be arranged in the first section a of the secondary side inlet pipe 80, and the other set can be arranged in the middle of the third section c of the secondary side outlet pipe 90.

[0129] The secondary flow sensor 230 can be installed in the middle of the third section c of the secondary inlet pipe 80, or in the middle of the third section c of the secondary outlet pipe 90.

[0130] The secondary side regulating valve can be installed in the third section c of the secondary side inlet pipe 80 near the bottom plate 102, or in the third section c of the secondary side outlet pipe 90 near the bottom plate 102.

[0131] In some embodiments, reference is also made to Figures 1 to 5 as well as Figure 14 The liquid-cooled heat exchange system may also include a replenishment tank 240 and a replenishment pump 280 disposed within the chassis 100, wherein the replenishment tank 240 is located near the top plate 101. The replenishment tank 240 and the heat exchanger 10 are arranged along the x-direction, and the replenishment tank 240 is located on the side of the heat exchanger 10 away from the distribution box 250.

[0132] The replenishment pump 280 can be fixedly connected to the outer wall of the replenishment tank 240, thereby shortening the path of the connecting pipeline between the replenishment pump 280 and the replenishment tank 240, which helps to save space. In addition, the replenishment pump 280 and the replenishment tank 240 are fixed together as a whole, which also facilitates installation and maintenance.

[0133] The coolant tank 240 can be connected to the secondary side inlet pipe 80 or the secondary side outlet pipe 90 via the coolant supply pipe 290. One end of the coolant pump 280 can be connected to an external coolant container, and the other end can be connected to the inside of the coolant tank 240, so as to pump the coolant in the external coolant container into the coolant tank 240, and then replenish the coolant in the secondary side circulation pipe through the coolant tank 240.

[0134] The replenishment pipeline 290 may also be equipped with a replenishment valve 300. When replenishing coolant to the secondary circulation pipeline, the speed of coolant replenishment can be adjusted by adjusting the opening of the replenishment valve 300.

[0135] As an optional implementation scheme, combined with Figure 15 The coolant tank 240 may have an interconnected coolant replenishment chamber 242 and a coolant storage chamber 241 inside, with the replenishment chamber 242 located on top of the storage chamber 241. A coolant replenishment pipe 290 is connected to the storage chamber 241. When coolant is replenished to the secondary circulation pipe using the coolant tank 240, the coolant in the storage chamber 241 enters the secondary circulation pipe through the replenishment pipe 290. When the coolant level in the storage chamber 241 is insufficient, the coolant replenishment pump 280 pumps coolant into the replenishment chamber 242, thereby replenishing the coolant in the storage chamber 241.

[0136] The coolant tank 240 may also be equipped with a quick-connect interface 243, which communicates with the coolant reservoir 241 and is also used to communicate with an external coolant container. When continuous coolant replenishment is required, the quick-connect interface 243 can be connected to the external coolant container. In this case, the coolant in the external coolant container can enter the reservoir 241 through the quick-connect interface 243, and then enter the coolant replenishment line 290. It is understood that when the quick-connect interface 243 is connected to the external coolant container, the coolant does not need to pass through the coolant replenishment chamber 242, thus improving the efficiency of coolant replenishment.

[0137] Refer again Figure 4 and Figure 5 A pump outlet check valve 310 may also be installed inside the chassis 100. The pump outlet check valve 310 is connected to the secondary side pump assembly 40 to prevent the coolant in the secondary side outlet pipe 90 from flowing back. Along the z-direction, the pump outlet check valve 310 is located on the side of the secondary side pump assembly 40 facing the heat exchanger 10, and the pump outlet check valve 310 is located close to the secondary side pump assembly 40.

[0138] Please refer to the above. Figure 1 , Figure 5 as well as Figure 14 A pressure stabilizing tank 270 can also be installed inside the chassis 100. The pressure stabilizing tank 270 is connected to the secondary side inlet pipe 80 or the secondary side outlet pipe 90 to stabilize the pressure of the secondary side circulation pipe. Specifically, when arranging the pressure stabilizing tank 270, it can be set on the side of the distribution box 250 away from the top plate 101, and along the x-direction, the pressure stabilizing tank 270 is located on the side of the heat exchanger 10 facing the distribution box 250, that is, the pressure stabilizing tank 270 is set directly below the distribution box 250. In this way, the space inside the chassis 100 can be fully utilized, thereby making reasonable allocation of the space inside the chassis 100 for easy operation and maintenance.

[0139] For example, the pressure stabilizing tank 270 can be connected to the replenishment line 290, which reduces the path between the pressure stabilizing tank 270 and the secondary circulation line, and facilitates the arrangement of the lines.

[0140] Understandable, for reference Figures 16 to 17 In this embodiment, the space within the chassis 100 can be roughly divided into four operable and maintainable areas along the x-direction. Specifically, from top to bottom, the four areas are: area S1 for maintaining the replenishment tank 240 and the heat exchanger 10; area S2 for maintaining the primary-side filtration device 110 and the secondary-side filtration device; area S3 for maintaining the sensors; and area S4 for maintaining the secondary-side pump group 40 and the various pipeline valves. Additionally, the chassis 100 also includes area S5 for maintaining the pressure stabilizing tank 270, which is approximately flush with area S3 in the x-direction.

[0141] In practical applications, the dimensions of the chassis 100 in the x, y, and z directions can be, for example, 600mm, 1200mm, and 200mm respectively. This allows the chassis 100 to be placed side by side with the liquid cooling cabinet, making the overall appearance more harmonious.

[0142] Based on this, combined Figure 16 and Figure 17 The distance between the ground and the bottom of the heat exchanger 10 can be 1600mm-1800mm; the height of area S1 can be 1500mm-1600mm; the height of area S2 can be 1100mm-1300mm; the height of area S3 can be 700mm-800mm; the height of area S4 can be 350mm-450mm; the dimension of area S5 in the y-direction can be 150mm-250mm; and the dimension of area S5 in the z-direction can be 500mm-650mm. Therefore, all of the above areas are within reach of both hands, which improves the convenience of maintenance.

[0143] Furthermore, in conjunction with the aforementioned embodiments, since both the front maintenance door 103 and the rear maintenance door 104 can be opened, when maintaining the liquid cooling equipment 1, the operator can maintain all the components inside the chassis 100 whether standing on the front or the back of the chassis 100, thereby further improving the convenience of operation and maintenance of the liquid cooling equipment.

[0144] In some other embodiments, the dimensions of the chassis 100 in the x, y and z directions may be 600mm, 1400mm and 200mm respectively, or they may be 600mm, 1400mm and 200mm respectively. This embodiment does not limit this.

[0145] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
