By transmitting low-temperature cooling liquid into the cooling flow channel through the first water inlet pipe, the cooling flow channel transmits the low-temperature cooling liquid to the liquid cooling plate to absorb the heat of the equipment to be cooled and convert it into high-temperature cooling liquid, and then the liquid cooling plate flows to the cooling flow channel and flows out through the first water outlet pipe, thereby improving the cooling efficiency of the equipment to be cooled in the machine room while reducing energy consumption, thereby reducing the use cost.

[0057] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the accompanying drawings.

Please refer to Figures 1 to 4 .

[0059] In a first aspect, the embodiment provides a liquid cooling system, which comprises at least one control unit 100, the control unit 100 is provided with a cooling flow channel, the cooling flow channel is connected with a first water inlet pipe 101 and a first water outlet pipe 102 respectively, the first water inlet pipe 101 is configured to transmit cooling liquid into the cooling flow channel, and the first water outlet pipe 102 is configured to transmit the cooling liquid in the cooling flow channel out; at least one liquid cooling plate 103 is arranged on a to-be-cooled equipment 10 in a machine room correspondingly, and the liquid cooling plate 103 is connected with the cooling flow channel.

[0060] Specifically, in the embodiment, the control unit 100 is a CDU (cooling device unit), which can adaptively distribute the cooling liquid according to the needs of each to-be-cooled equipment 10, so as to ensure that each to-be-cooled equipment 10 can be cooled sufficiently.

[0061] The control unit 100 further comprises valves, pumps and other components, and the flow rate and pressure of the cooling liquid in the cooling flow channel can be accurately controlled by adjusting the valves, pumps and other components, so as to ensure the stable flow of the cooling liquid in the liquid cooling system and avoid the problems of uneven cooling or high energy consumption caused by excessive or insufficient flow.

[0062] Meanwhile, in the embodiment, the control unit 100 can also monitor the operating state of the liquid cooling system, the temperature and pressure of the cooling liquid and other parameters in real time, and when the temperature and pressure of the cooling liquid or other parameters do not match the parameters of the preset normal operating state, the control unit 100 can send an alarm information to prompt the relevant operator to handle.

[0063] Specifically, in the embodiment, the liquid cooling system comprises the first water inlet pipe 101 and the first water outlet pipe 102, wherein the first water inlet pipe 101 and the first water outlet pipe 102 are connected with the cooling flow channel, the cooling flow channel is connected with the liquid cooling plate 103, so that low-temperature cooling liquid can be transmitted into the cooling flow channel through the first water inlet pipe 101, the low-temperature cooling liquid enters the cooling flow channel through the first water inlet pipe 101, the control unit 100 can adjust the flow rate and pressure of the low-temperature cooling liquid adaptively according to the cooling needs, and then transmit the low-temperature cooling liquid into the liquid cooling plate 103, so as to absorb the heat of the to-be-cooled equipment 10 through the liquid cooling plate 103 arranged on the to-be-cooled equipment 10.

[0064] The first water inlet pipe 101 is provided with a first water inlet 1011, and the cooling liquid enters the first water inlet pipe 101 by being added into the first water inlet 1011. The first water outlet pipe 102 is provided with a first water outlet 1021, and the cooling liquid flows out of the first water outlet pipe 102 through the first water outlet 1021.

[0065] In the embodiment, the heat dissipation device 10 is a cabinet, and the liquid cooling plate 103 is installed on the back of the cabinet and connected to the cabinet by bolt fixing or buckling connection, so that the liquid cooling plate 103 can be directly added to the existing cabinet without changing the structure of the cabinet, greatly improving the convenience of the modification of the computer room and the data center.

[0066] In other embodiments, the liquid cooling plate 103 can also be directly installed in the interior of the heat dissipation device 10 when the heat dissipation device 10 is produced, that is, the heat dissipation device 10 is directly produced in the form of a back plate type liquid cooling heat dissipation device 10.

[0067] It should be noted that the combination of the liquid cooling plate 103 and the heat dissipation device 10 is not limited in the embodiment, and can be adaptively selected according to actual needs.

[0068] Specifically, when the cooling liquid in the liquid cooling plate 103 fully absorbs the heat of the heat dissipation device 10, the low-temperature cooling liquid is converted into high-temperature cooling liquid, and the high-temperature cooling liquid is transmitted to the cooling flow channel. The flow and pressure of the high-temperature cooling liquid can be adjusted by the control unit 100 when flowing, so that the high-temperature cooling liquid can be cooled to a certain extent when flowing in the first outlet pipe 102.

[0069] At the same time, in order to further reduce the use cost, in an optional embodiment, the first outlet 1021 of the first outlet pipe 102 and the first inlet 1011 of the first inlet pipe 101 are connected and arranged, and a radiator is arranged therebetween. After the high-temperature cooling liquid in the first outlet pipe 102 is fully cooled by the radiator, it is recycled into the first inlet pipe 101, thereby realizing the recycling of the cooling liquid, reducing the consumption and replacement frequency of the cooling liquid, and realizing the continuous use and efficient cooling of the cooling liquid by forming a closed loop circulation circuit of the liquid cooling system, thereby ensuring the stability and reliability of the liquid cooling system.

[0070] In addition, in other optional embodiments, a fan can also be arranged at the first outlet pipe 102, and the first outlet 1021 of the first outlet pipe 102 and the first inlet 1011 of the first inlet pipe 101 are directly connected, so that the airflow generated by the fan accelerates the heat dissipation of the high-temperature cooling liquid. When the high-temperature cooling liquid flows through the first outlet pipe 102, the airflow generated by the fan can carry away the heat released by the cooling liquid, thereby accelerating the cooling speed of the cooling liquid.

[0071] Please continue to refer to Figures 1 to 4In an optional embodiment, the liquid cooling system further comprises at least one second water inlet pipe 104 and at least one first filter 106, one end of the second water inlet pipe 104 is in communication with the first flow channel outlet 1001 of the cooling flow channel, and the other end is in communication with the liquid cooling plate 103, and the first filter 106 is arranged on the second water inlet pipe 104.

[0072] Specifically, in the embodiment, the liquid cooling system further comprises a second water inlet pipe 104 and a first filter 106, one end of the second water inlet pipe 104 is in communication with the first flow channel outlet 1001 of the cooling flow channel, and the other end is in communication with the liquid cooling plate 103, so as to transmit the low-temperature cooling liquid in the cooling flow channel to the liquid cooling plate 103, and the first filter 106 is arranged on the second water inlet pipe 104, so as to filter the cooling liquid entering the liquid cooling plate 103, avoid the impurities in the cooling liquid from entering the liquid cooling plate 103, and block the cooling channel in the liquid cooling plate 103, and affect the normal use of the liquid cooling plate 103.

[0073] In the embodiment, the first filter 106 is a Y-shaped filter. The Y-shaped filter mainly comprises a main pipe, a blowdown port and a filter element. The filter element can be a filter screen or other elements capable of filtering. The filter element is arranged in the main pipe, and the main pipe can allow the cooling liquid to pass through, so as to intercept the impurities on one side of the filter element. The blowdown port is located at the bottom of the main pipe and on the side where the impurities are deposited on the filter element, and forms a "Y" shape with the main pipe, so that when the impurities are intercepted on the filter element, they can directly deposit on the blowdown port due to their own gravity.

[0074] By adopting the Y-shaped filter, the impurities can be conveniently collected, the blowdown operation is simplified, and the cleaning and efficient operation of the liquid cooling system are ensured.

[0075] In addition, it should be noted that in other embodiments, the type and specification of the first filter 106 can also be adaptively selected, and the present embodiment does not make any limitation in this regard.

[0076] Meanwhile, in the embodiment, the liquid cooling system further comprises a second water outlet pipe 105, one end of the second water outlet pipe 105 is in communication with the first flow channel inlet 1002 of the cooling flow channel, and the other end is in communication with the liquid cooling plate 103, so as to transmit the high-temperature cooling liquid in the liquid cooling plate 103 to the cooling flow channel.

[0077] Specifically, in the embodiment, the cooling flow channel has a first flow channel water outlet 1001, a first flow channel water inlet 1002, a second flow channel water outlet 1003, and a second flow channel water inlet 1004, wherein the first flow channel water outlet 1001 is in communication with the first water outlet pipe 102, the first flow channel water inlet 1002 is in communication with the first water inlet pipe 101, the second flow channel water outlet 1003 is in communication with the second water inlet pipe 104, and the second flow channel water inlet 1004 is in communication with the second water outlet pipe 105, so that the low-temperature cooling liquid in the first water inlet pipe 101 can enter the cooling flow channel through the first flow channel water inlet 1002, and then the low-temperature cooling liquid enters the liquid cooling plate 103 after flowing through the second water inlet pipe 104 through the second flow channel water outlet 1003. When the cooling liquid absorbs heat at the liquid cooling plate 103, the high-temperature cooling liquid enters the second water outlet pipe 105 and enters the cooling flow channel through the second flow channel water inlet 1004, and the high-temperature cooling liquid in the cooling flow channel enters the first water outlet pipe 102 through the second flow channel water outlet 1003 and is discharged through the first water outlet 1021, thereby realizing a heat dissipation process.

[0078] Specifically, in the embodiment, the number of liquid cooling plates 103 can be multiple, and the multiple liquid cooling plates 103 are arranged one by one corresponding to the multiple equipment to be cooled 10 in the machine room, so as to ensure the heat dissipation effect of each equipment to be cooled 10.

[0079] Wherein, since the number of controls that each control unit 100 can realize is limited, the number of control units 100 can be adaptively set to multiple according to actual needs, so as to realize precise coverage of each equipment to be cooled 10 with heat dissipation demand.

[0080] Correspondingly, when the number of liquid cooling plates 103 and control units 100 is multiple, the first water inlet pipe 101 further has multiple first branches 1013, the first water outlet pipe 102 has multiple second branches 1023, the second water inlet pipe 104 has multiple third branches 1041, and the second water outlet pipe 105 has multiple fourth branches 1051.

[0081] Wherein, the number of first branches 1013 and second branches 1023 is the same as the number of control units 100, each control unit 100 corresponds to a first branch 1013 and a second branch 1023, the number of third branches 1041 and fourth branches 1051 is the same as the number of liquid cooling plates 103, and each liquid cooling plate 103 corresponds to a third branch 1041 and a fourth branch 1051.

[0082] Specifically, the low-temperature cooling liquid flows into the first water inlet pipe 101 through the first water inlet 1011, and then flows to each control unit 100 through each first branch 1013. The first flow outlet 1001 of the cooling flow channel of each control unit 100 transmits the low-temperature cooling liquid to the second water inlet pipe 104, and then the high-temperature cooling liquid is converted by absorbing the heat of the equipment to be cooled 10 at each liquid cooling plate 103 through each third branch 1041. The high-temperature cooling liquid is collected to the second water outlet pipe 105 through each fourth branch 1051, and then flows into the cooling flow channel of each control unit 100, and then is collected to the first water outlet 1021 of the first water outlet pipe 102 through each second branch 1023.

[0083] At the same time, when the second water inlet pipe 104 has a plurality of third branches 1041, each third branch 1041 corresponds to a first filter 106, so as to ensure that the cooling liquid entering each liquid cooling plate 103 can be filtered.

[0084] In an optional embodiment, the number of equipment to be cooled 10 is eight, and the number of liquid cooling plates 103, third branches 1041 and fourth branches 1051 corresponding to the equipment to be cooled 10 is also eight, and the number of control units 100, first branches 1013 and second branches 1023 is three. Among them, two control units 100 respectively control the cooling liquid flowing to four equipment to be cooled 10, and the other control unit 100 remains standby or shutdown state as a backup, so that when the working control unit 100 fails or needs to be maintained, the standby control unit 100 can be quickly activated, thereby ensuring the supply and control of the cooling liquid, improving the reliability of the liquid cooling system, and reducing the problem of local hot spots caused by the failure of the liquid cooling system to effectively cool some equipment to be cooled 10.

[0085] It should be noted that in actual application, since the possibility of simultaneous failure of two control units 100 is small, the number of standby control units 100 in this embodiment is one, but based on the reliability guarantee, the number of standby control units 100 can also be adjusted to be the same as the number of working control units 100 to avoid the situation that multiple working control units 100 fail at the same time.

[0086] At the same time, those skilled in the art can also adaptively select the number of liquid cooling plates 103 corresponding to each control unit 100 according to actual needs, and this embodiment does not make any limitation on this. The above number is only an exemplary description.

[0087] In an optional embodiment, the liquid cooling system further comprises a first bypass valve 107, a first bypass pipe 108 and a first switch valve 109, the first switch valve 109 is arranged on the second water inlet pipe 104, both ends of the first bypass pipe 108 are in communication with the second water inlet pipe 104, both ends of the first bypass pipe 108 are located on both sides of the first filter 106 respectively, and the first bypass valve 107 is arranged on the first bypass pipe 108.

[0088] Specifically, both ends of the first bypass pipe 108 are in communication with the second water inlet pipe 104 and are located on both sides of the first filter 106 respectively. When the first filter 106 is normally used, the first switch valve 109 remains in an open state, and the first bypass valve 107 remains in a closed state, so that the cooling liquid can enter the liquid cooling plate 103 after being filtered by the first filter 106. When the first filter 106 needs to be disassembled for cleaning or replacement, the first switch valve 109 can be closed first, and the first bypass valve 107 can be opened, so that the cooling liquid can enter the liquid cooling plate 103 through the first bypass pipe 108, thereby not interfering with the normal operation of the liquid cooling system.

[0089] Specifically, both ends of the first bypass pipe 108 are in communication with the second water inlet pipe 104 and are located on both sides of the first filter 106 respectively. When the first filter 106 is normally used, the first switch valve 109 remains in an open state, and the first bypass valve 107 remains in a closed state, so that the cooling liquid can enter the liquid cooling plate 103 after being filtered by the first filter 106. When the first filter 106 needs to be disassembled for cleaning or replacement, the first switch valve 109 can be closed first, and the first bypass valve 107 can be opened, so that the cooling liquid can enter the liquid cooling plate 103 through the first bypass pipe 108, thereby not interfering with the normal operation of the liquid cooling system.

[0090] In an optional embodiment, the first switch valve 109 can be a one-way valve, so that after the first switch valve 109 is closed, the cooling liquid at the liquid cooling plate 103 can be prevented from flowing back to the first filter 106 through the second water inlet pipe 104.

[0091] In addition, when the cooling liquid enters the liquid cooling plate 103 through the first bypass pipe 108, a filter screen or other filtering elements can be adaptively installed in the first bypass pipe 108, so that during the disassembly, cleaning or maintenance of the first filter 106, impurities entering the liquid cooling plate 103 through the first bypass pipe 108 can be prevented from causing the cooling channel in the liquid cooling plate 103 to be blocked, thereby affecting the normal use of the liquid cooling plate 103.

[0092] Specifically, in the present embodiment, the number of the first bypass pipe 108 is the same as that of the second water inlet pipe 104, each second water inlet pipe 104 corresponds to a first bypass pipe 108, and each first bypass pipe 108 corresponds to a first bypass valve 107, so that one-to-one correspondence is achieved, and the normal flow of the cooling liquid is not interfered with when each first filter 106 is replaced, thereby affecting the normal operation of the entire liquid cooling system.

[0093] In an optional embodiment, the liquid cooling system further comprises at least one sensing assembly 110 arranged on the first water inlet pipe 101 and / or the first water outlet pipe 102 to detect the flow of the cooling liquid.

[0094] Specifically, in an optional embodiment, the liquid cooling system further comprises at least one sensing assembly 110 arranged on the first water inlet pipe 101 to obtain the flow data of the cooling liquid in the first water inlet pipe 101. The sensing assembly 110 comprises a temperature sensor 1101, a pressure sensor 1102 and a flow sensor 1103, so as to monitor the temperature, pressure and flow of the cooling liquid in the first water inlet pipe 101 in real time.

[0095] Specifically, the temperature of the cooling liquid in the first water inlet pipe 101 can be detected to determine the heat load of the current liquid cooling system. If the temperature of the cooling liquid in the first water inlet pipe 101 is high, the subsequent cooling liquid can be cooled before entering the first water inlet pipe 101 to avoid the heat dissipation effect of the liquid cooling system.

[0096] The pressure of the cooling liquid in the first water inlet pipe 101 can be detected to ensure that the flow pressure of the cooling liquid is within a safe range. If the pressure is too high or too low, the operator can be informed in time to determine the specific fault point and avoid shutdown or damage of the entire liquid cooling system.

[0097] The flow rate of the cooling liquid in the first water inlet pipe 101 can be detected to prevent the first water inlet pipe 101 from being blocked. When the flow rate suddenly decreases, it may indicate that there is a blockage in the first water inlet pipe 101, which needs to be cleaned.

[0098] By combining the temperature, pressure and flow data, the operator can obtain the running data of the entire liquid cooling system in real time. When the heat dissipation demand is large, the temperature can be lowered or the flow rate can be increased to improve the heat dissipation efficiency. When the heat dissipation demand is small, the flow rate can be reduced to save energy consumption.

[0099] In another optional embodiment, the sensing assembly 110 is arranged on the first water outlet pipe 102 to detect the flow data of the cooling liquid in the first water outlet pipe 102. The sensing assembly 110 comprises a temperature sensor 1101, a pressure sensor 1102 and a flow sensor 1103, so as to monitor the temperature, pressure and flow of the cooling liquid in the first water outlet pipe 102 in real time.

[0100] Specifically, in combination with the temperature, pressure and flow data, the operator can obtain the operation data of the entire liquid cooling system in real time. When the heat dissipation demand is large, the temperature of the cooling liquid in the first outlet pipe 102 is high, so the flow size can be adaptively adjusted to improve the heat dissipation efficiency. When the heat dissipation demand is small, the temperature of the cooling liquid in the first outlet pipe 102 is low, so the flow can be adaptively reduced to ensure that the cooling liquid can fully exchange heat with the equipment 10 to be cooled, thereby saving energy consumption.

[0101] In another optional embodiment, the first inlet pipe 101 and the first outlet pipe 102 are both provided with the sensing assembly 110, so that the inlet and outlet of the cooling liquid can be monitored to ensure the stability of the entire liquid cooling system.

[0102] In addition, it should be noted that, in addition to the temperature sensor 1101, the pressure sensor 1102 and the flow sensor 1103, the sensing assembly 110 in the present embodiment can also adaptively include other devices capable of detecting or sensing according to actual needs, and the present embodiment does not make any limitation on this.

[0103] Please continue to refer to Figures 1 to 4 In an optional embodiment, the liquid cooling system further comprises a second filter 111, and the second filter 111 is arranged on the first inlet 1011 of the first inlet pipe 101.

[0104] Specifically, in the present embodiment, the first inlet pipe 101 has a first inlet 1011, the first outlet pipe 102 has a first outlet 1021, and the liquid cooling system further comprises a second filter 111 arranged on the first inlet 1011. Thus, the cooling liquid entering the first inlet pipe 101 from the first inlet 1011 can be filtered, thereby improving the purity of the cooling liquid and the operation efficiency of the liquid cooling system. At the same time, filtering the impurities in the cooling liquid can avoid friction and wear between the cooling liquid and the pipeline, thereby enhancing the reliability and durability of the liquid cooling system.

[0105] In the present embodiment, the second filter 111 is a filter screen, and the second filter 111 is detachably arranged on the first inlet 1011 to facilitate the operator to disassemble and clean.

[0106] In an optional embodiment, the liquid cooling system further comprises a second switch valve 112 and a third switch valve 113, the second switch valve 112 is arranged on the second inlet 1012 of the first inlet pipe 101, and the third switch valve 113 is arranged on the second outlet 1022 of the first outlet pipe 102.

[0107] Specifically, in the present embodiment, the liquid cooling system further comprises a second switch valve 112 and a third switch valve 113, the first water inlet pipe 101 has a second water inlet 1012, the first water outlet pipe 102 has a second water outlet 1022, the second switch valve 112 is arranged on the second water inlet 1012, and the third switch valve 113 is arranged on the second water outlet 1022.

[0108] In normal operation, the second switch valve 112 and the third switch valve 113 are kept in a closed state, and when blockage occurs near the first water inlet 1011 or the second water outlet 1022, the second switch valve 112 or the third switch valve 113 can be opened, thereby avoiding the entire liquid cooling system from being shut down due to blockage.

[0109] Specifically, the first water inlet 1011 and the first water outlet 1021 are each provided with an inlet and outlet valve 119, and when blockage occurs at the first water inlet 1011, causing the cooling liquid to fail to flow or enter smoothly, the inlet and outlet valve 119 can be closed, and the second switch valve 112 can be opened, so that the cooling liquid is transmitted to the first water inlet pipe 101 through the second water inlet 1012, thereby not affecting the normal operation of the entire liquid cooling system.

[0110] Similarly, when blockage occurs at the first water outlet 1021, causing the cooling liquid to fail to flow or flow out smoothly, the inlet and outlet valve 119 can be closed, and the third switch valve 113 can be opened, so that the cooling liquid can flow out through the second water outlet 1022, thereby not affecting the normal operation of the entire liquid cooling system.

[0111] Correspondingly, to avoid the problem of backflow of the cooling liquid from the first water inlet 1011 during maintenance of the first water inlet 1011 or the first water outlet 1021, the inlet and outlet valve 119 in the present embodiment is a backflow valve that allows the cooling liquid to pass through in only one direction, thereby avoiding the problem of backflow.

[0112] In an optional embodiment, the number of first water inlets 1011 and first water outlets 1021 is two, and the first water inlets 1011 and the first water outlets 1021 are arranged in two groups, and the two groups of first water inlets 1011 and first water outlets 1021 are arranged on the two sides of the first water inlet pipe 101, thereby ensuring that the cooling liquid is more evenly distributed and flows in the system. By adopting the above steps, not only the cooling efficiency can be improved, but also the problem of local overheating or insufficient cooling caused by uneven flow can be reduced. Secondly, the configuration of double first water inlets 1011 and double first water outlets 1021 improves the convenience of cleaning, maintenance and maintenance of the liquid cooling system. The operator can selectively close or operate a certain first water inlet 1011 or first water outlet 1021 as needed without affecting the normal operation of the entire system.

[0113] In an optional embodiment, the number of the second water outlets 1022 and the second water inlets 1012 is two, and the number of the third switch valve 113 and the second switch valve 112 is also two, so that when both of the two first water inlets 1011 or both of the two first water outlets 1021 fail, the cooling liquid can continuously and stably enter or flow out of the liquid cooling system. In addition, the second water outlets 1022 and the second water inlets 1012 are not limited to the case where the first water inlets 1011 and the first water outlets 1021 fail, but can also be opened when the heat dissipation demand is too high, the flow of the cooling liquid is insufficient, or the temperature of the cooling liquid is too high, thereby further increasing the heat dissipation efficiency of the liquid cooling system.

[0114] By adopting the double-path design of the second water outlets 1022, the second water inlets 1012, and the third switch valve 113 and the second switch valve 112, not only the redundancy and reliability of the liquid cooling system are enhanced, but also the response capability and safety of the liquid cooling system in the face of sudden conditions are improved, so that the liquid cooling system can better adapt to various complex application scenarios and working environments.

[0115] In an optional embodiment, the liquid cooling system further comprises at least one circulating pump 114, which is arranged on the first water inlet pipe 101 and located on the side of the control unit 100 away from the liquid cooling plate 103.

[0116] Specifically, in the present embodiment, the liquid cooling system further comprises the circulating pump 114, which is arranged on the first water inlet pipe 101, so as to control the flow rate and pressure of the cooling liquid in the first water inlet pipe 101, thereby ensuring the smoothness of the flow of the cooling liquid and avoiding the problem of insufficient power and poor flow.

[0117] When the number of the control units 100 is multiple, the number of the circulating pumps 114 can be the same as the number of the control units 100, and correspondingly, the first water inlet pipe 101 has multiple first branches 1013, and each circulating pump 114 is arranged on the first branch 1013, so as to ensure that each control unit 100 can obtain sufficient flow rate and pressure of the cooling liquid, and also make the liquid cooling system be able to more accurately control the cooling effect of each region. At the same time, by making each circulating pump 114 work independently, the flow rate and pressure can be accurately adjusted according to the demand of the respective control unit 100, thereby improving the flexibility and response speed of the liquid cooling system, and also helping to reduce energy waste and unnecessary system loss.

[0118] In addition, it should be noted that the operator can also adaptively arrange the circulating pump 114 at other positions of the liquid cooling system. For example, the circulating pump 114 can be arranged on the first water outlet pipe 102 to control the outlet flow rate and pressure of the cooling liquid. For this, the present embodiment does not make any limitation.

[0119] Please continue to refer to Figures 1 to 4 In an optional embodiment, the liquid cooling system further comprises a second bypass valve 115, a second bypass pipe 116 and a fourth switch valve 117, the fourth switch valve 117 is arranged on the first water inlet pipe 101, both ends of the second bypass pipe 116 are connected with the first water inlet pipe 101, and both ends of the second bypass pipe 116 are located on both sides of the circulating pump 114, and the second bypass valve 115 is arranged on the second bypass pipe 116.

[0120] Specifically, in the embodiment, the liquid cooling system further comprises the second bypass pipe 116 and the second bypass valve 115, both ends of the second bypass pipe 116 are connected with the first water inlet pipe 101 on both sides of the circulating pump 114, so that the cooling liquid can flow into the control unit 100 through the second bypass pipe 116 when the circulating pump 114 fails or needs to be maintained.

[0121] Specifically, in the embodiment, the fourth switch valve 117 is arranged at the circulating pump 114, in normal operation, the fourth switch valve 117 is opened to enable the cooling liquid to flow smoothly into the circulating pump 114, when the circulating pump 114 fails or needs to be maintained, the fourth switch valve 117 is closed, and the second bypass valve 115 is opened, so that the cooling liquid can flow into the control unit 100 through the second bypass pipe 116, thereby realizing the maintenance of the circulating pump 114 without stopping the entire liquid cooling system, and ensuring the stability of the operation of the liquid cooling system.

[0122] In an optional embodiment, the fourth switch valve 117 and the second bypass valve 115 are both one-way valves, which only allow one-way passage of the cooling liquid, thereby avoiding the problem of backflow of the cooling liquid during maintenance.

[0123] In other optional embodiments, each circulating pump 114 can correspond to two fourth switch valves 117, and the two fourth switch valves 117 are arranged on both sides of the circulating pump 114, thereby being able to stop the cooling liquid on both sides of the circulating pump 114, and ensuring the normal maintenance of the circulating pump 114.

[0124] In an optional embodiment, the control unit 100, the first water inlet pipe 101 and the first water outlet pipe 102 are arranged below the floor of the machine room.

[0125] Specifically, in the embodiment, a containing cavity is formed between the floor of the machine room and the ground to contain the control unit 100, the first water inlet pipe 101 and the first water outlet pipe 102, so that when a traditional air-cooled machine room is transformed into a liquid cooling system, no additional arrangement space is needed, the transformation cost is greatly reduced, and the transformation efficiency is improved. Among them, the liquid cooling plate 103 is arranged above the floor because it needs to be installed in cooperation with the equipment to be cooled 10.

[0126] In addition, since the control unit 100 will inevitably vibrate to a certain extent during operation, in the embodiment, the connection between the first water inlet pipe 101 and the control unit 100, the connection between the first water outlet pipe 102 and the control unit 100, and the connection between the liquid cooling plate 103 and the control unit 100 are all provided with a soft joint 118, so as to absorb the vibration generated by the operation of the control unit 100, avoid the vibration from being transmitted to other pipelines, and thereby prolong the service life of the liquid cooling system.

[0127] Among them, the soft joint 118 is a connecting element with elasticity and flexibility, which can absorb and relieve the impact and stress caused by vibration to a certain extent.

[0128] In an exemplary embodiment, the soft joint 118 is a silica gel hose.

[0129] In addition, in the embodiment, a plurality of gate valves can be adaptively arranged on the liquid cooling system, so as to accurately control the flow of the cooling liquid and ensure the reliability of the entire liquid cooling system. For example, a gate valve is arranged at the connection between the first water inlet pipe 101 and the control unit 100.

[0130] It should be noted that the operator can adaptively select the specific arrangement position of the gate valve, and the embodiment does not make any limitation on this.
