Description

Technical Field

[0001] This specification relates to the field of heat exchange technology, and in particular to a liquid cooler and a liquid cooling system. Background Technology

[0002] With the development of network technology, the application scope of servers, which carry applications and data storage, is also expanding. During deployment, due to the large number of servers and other ICT (Information and Communication Technology) devices, how to reliably dissipate heat from these ICT devices is a problem that urgently needs to be solved by those skilled in the art. Liquid cooling, as an efficient and reliable heat dissipation method, is widely used.

[0003] In current implementations, ICT equipment needs to be immersed in a liquid cooler filled with a low-boiling-point coolant. When maintaining an ICT device, the top cover of the liquid cooler needs to be opened and the device removed. During this process, because the inside of the liquid cooler is completely exposed, the coolant is affected by the external environment and gradually vaporizes, overflowing from the liquid cooler, resulting in coolant waste and reducing the maintenance efficiency of the liquid cooling system.

[0050] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this specification.

[0051] This application provides a liquid cooling cabinet 100, such as Figure 1 , 2 As shown, it includes:

[0052] The liquid cooling box 101 can be configured in terms of size and shape according to actual conditions. Generally speaking, the liquid cooling box 101 can be configured as a rectangle.

[0053] At least one partition 102 is disposed in the liquid cooling box 101, dividing the interior of the liquid cooling box 101 into at least two cavities 103. A groove can be formed in the side wall of the liquid cooling box 101, and the partition 102 can slide into the groove for a more reliable connection. A sealant can be applied between the groove and the partition 102 to improve the reliability of the connection. At the bottom of the liquid cooling box 101, each cavity 103 is interconnected, which can achieve the balance of coolant in the cavity 103, and the coolant in the liquid cooling box 100 can be replenished by external coolant. Of course, the connection between the partition 102 and the liquid cooling box 101 is not limited to the above method, and can also be connected by welding or welding and sealant.

[0054] At least two cavity top covers 104, each cavity top cover 104 is disposed at the top 103A opening of the cavity 103 to seal the cavity 103. A sealing gasket or the like can be provided in the area where the edge of the cavity top cover 104 overlaps with the top 103A of the cavity 103 to improve the sealing performance of the cavity top cover 104 to the cavity 103 and prevent the vaporized coolant from overflowing from the gap between the cavity 103 and the cavity top cover 104.

[0055] Main pipe 105, one end of which can be connected to the coolant outlet and coolant inlet of liquid cooling system 200;

[0056] The first cooling conduit 106 includes at least two flexible conduits 106A and at least two first branch conduits 106B. The main conduit 105 and the first branch conduits 106B are connected by flexible conduits 106A. Different first branch conduits 106B pass through the cavity top covers 104 of different cavities 103, facing the corresponding cavity 103 side. The first branch conduits 106B can be coiled inside the cavity top cover 104 to increase the heat exchange area. The flexible conduits 106A can be straightened when the cavity top cover 104 is opened, allowing a portion of the flexible conduit 106A to... Figure 3 , 4 The flexible conduit 106A extends into the cavity top cover 104 to release the distance the cavity top cover 104 can open. When the cavity top cover 104 is closed, the flexible conduit 106A can be pulled out of the cavity 103 to ensure the cavity top cover 104 is tightly closed. Alternatively, the flexible conduit 106A can be straightened between the cavity 103 and the cavity top cover 104 when the cavity top cover 104 is opened, and bent within the cavity 103 when the cavity top cover 104 is closed. The specific configuration is not limited to this and can be implemented according to actual needs. In this way, the opening and closing process of the cavity top cover 104A does not affect the coolant circulation of the first cooling conduit 106 provided on the cavity top cover 104. The opening method of the cavity top cover 104 can be a rotation method including a pivot or a direct removal method without a pivot; there are no restrictions on this. Figure 3 For the removal method, since the cavity top cover 104 needs to be removed and placed aside, the flexible conduit 106A needs to allow sufficient distance. If a rotation method is used, sufficient space needs to be provided to allow for rotating and opening the cavity top cover 104. The specific method used can be set according to actual needs and is not limited.

[0057] After the liquid cooler 100 is filled with coolant and the liquid cooling system 200 is started, the coolant can dissipate heat from the ICT equipment 300 submerged in it. After the external circulating coolant is input into the main pipeline 105, it is distributed to the first branch pipeline 106B through the flexible pipeline 106A. After the first branch pipeline 106B comes into contact with the vaporized coolant, it cools the vaporized coolant and drips back into the cavity 103, thereby realizing the heating and cooling cycle of the coolant in the cavity 103. When maintenance is required on an ICT device 300 in a cavity 103, the operator first shuts down the selected ICT device (such as the first ICT device 300A), opens the top cover 104A of the cavity containing the first ICT device 300A, removes the first ICT device 300A for maintenance, and closes the top cover 104A. Maintaining a single cavity top cover 104A can avoid excessive contact of the coolant with the surrounding environment, which would lead to excessive vaporization of the coolant and waste, thus improving the maintenance efficiency of the liquid cooling system.

[0058] In order to cool the coolant in the cavity, the liquid cooler 100, such as Figure 5 As shown, it also includes:

[0059] The second cooling pipe 107 includes at least two second branch pipes 107A, which are connected to the main pipe 105. Different second branch pipes 107A pass through the side walls of different cavities 103. The second branch pipes 107A can be coiled around the side walls of the cavities 103 to increase the contact area between the second branch pipes 107A and the coolant in the cavities 103, thereby providing auxiliary cooling for the coolant.

[0060] When the liquid cooling system 200 detects that the coolant temperature has risen to a certain value, the circulation of coolant in the second branch pipe 107A can be started to cool the coolant in the cavity 103. Alternatively, the second branch pipe 107A can start circulating when the liquid cooling system 200 is working to assist in cooling the coolant in the cavity 103. When the coolant temperature is detected to have risen to a certain value, the coolant in the second branch pipe 107A can be cooled by a steam compressor or other equipment to increase the amount of heat that the second branch pipe 107A can remove and lower the temperature of the coolant in the cavity 103.

[0061] Furthermore, the second branch pipe 107A can be connected to the same main pipe 105 as the first branch pipe 106B, or they can be connected to different main pipes, without restriction.

[0062] Optionally, fins are provided on the branch pipes (i.e., the first branch pipe 106B and the second branch pipe 107A). The fins can further increase the heat dissipation area and improve the heat dissipation effect.

[0063] Optional, liquid cooler 100, such as Figure 6 As shown, it also includes:

[0064] Exhaust module 108;

[0065] Exhaust module 108 includes:

[0066] Exhaust pipe 108A, one end of which is connected to cavity 103 through a through hole at the top of cavity 103;

[0067] Gas-liquid separator 108B is connected to the other end of exhaust pipe 108A and includes exhaust valve 108C;

[0068] The liquid storage tank 108D is connected to the return pipe 108E and stores the coolant condensed in the gas-liquid separator 108B. It is connected to the bottom of the cavity 103 through the return pipe 108E.

[0069] The cavity 103 can be understood to contain a gas phase region and a liquid phase region. The gas phase region refers to the part of the cavity 103 filled with gas, and the liquid phase region refers to the part of the cavity 103 filled with coolant.

[0070] When cavity 103 is closed by cavity top cover 104, some coolant will vaporize due to heat dissipation for ICT equipment 300, filling the vapor phase region. If the heat exchange capacity of the first branch pipe 106B is insufficient to liquefy all the vaporized coolant retained in the vapor phase region, the pressure in the vapor phase region will gradually increase, causing an increase in pressure in cavity 103, further intensifying coolant vaporization, or this pressure may be applied to cavity top cover 104, causing deformation of cavity top cover 104, or when opening the wall top cover 104, the thrust on cavity top cover 104 may damage flexible pipe 106A. Therefore, by setting a through hole in the upper part of the cavity 103 (which can be understood as the gas phase zone) and connecting it to the exhaust pipe 108A, excess gas in the gas phase zone is periodically or in real time drawn into the gas-liquid separator 108B. During this process, heat exchange is carried out through components such as the heat exchanger 109 to reduce the temperature in the exhaust pipe 108A, causing the gas to liquefy, drip into the gas-liquid separator 108B and be stored in the liquid storage tank 108D. Afterward, the coolant stored in the liquid storage tank 108D can be pumped back to the cavity 103 through the return pipe 108E. A liquid pump can also be installed on the return pipe 108E.

[0071] In this way, the pressure in the gas phase region can be reduced, and the coolant in the cavity 103 can be replenished through external circulation, avoiding frequent coolant replenishment, reducing the cost of the liquid cooling system, and improving the maintenance efficiency of the liquid cooling system.

[0072] Optional, liquid cooler 100, such as Figure 1 As shown, it also includes:

[0073] The top cover 110 is located on top of the liquid-cooled box 101 and seals the liquid-cooled box 101.

[0074] Due to vaporization, some of the vaporized coolant in cavity 103 will still overflow from the gap between cavity top cover 104 and cavity 103, resulting in coolant waste and causing some air pollution. In order to further improve the maintenance efficiency and safety of the liquid cooler 100, the top cover 110 is used for further sealing, so that some of the gas overflowing from cavity 103 can be sealed in the liquid cooler 100 and condensed on the top cover 104 under the cooling effect of the first cooling pipe 106, preventing gas from overflowing. When the operator performs maintenance on the liquid cooler 100, they can directly wipe or collect the condensed coolant on the top cover 104, thus improving the maintenance efficiency and safety of the liquid cooler 100.

[0075] Correspondingly, this application also provides a liquid cooling system 200, such as Figure 3 , 4As shown, a liquid cooler 100 including any of the above and a controller (not shown) are provided, and coolant is contained in the cavity 103 of the liquid cooler 100.

[0076] A controller can be installed in the liquid cooling system 200 to control various devices in the liquid cooling system 200, thereby achieving the cooling of the ICT equipment 300 by the liquid cooling system 200.

[0077] Optional, liquid cooling system 200, such as Figure 7 As shown, it also includes:

[0078] A steam compressor 201 is installed on the second branch pipe 107A of the liquid cooler 100;

[0079] At least two temperature sensors 202 are provided, with different temperature sensors 202 set in the liquid phase zone 203 of different chambers 103, to monitor the temperature in each chamber 103, and to increase the power of the steam compressor 201 by the controller when the temperature is higher than the preset temperature.

[0080] Multiple temperature sensors 202 can be installed in the liquid cooling system 200. One temperature sensor 202 can be installed in the liquid phase zone 203 of a cavity 103 to monitor the temperature of the coolant in that cavity 103. The temperature of the coolant is close to the temperature of the ICT device 300 in the cavity 103. A preset temperature can be set in the controller. This preset temperature indicates that when the temperature in the cavity 103 rises to a certain value, the first cooling pipe 106 on the cavity top cover 104 alone cannot cool the coolant in the cavity 103. At this time, the controller can control the steam compressor 201 connected to the second branch pipe 107A (or, it can be connected to the main pipe 105, depending on actual needs) to increase its power, liquefying the gas in the cooling pipe and lowering the temperature of the coolant. This allows the coolant circulating through the first cooling pipe 106 and the second cooling pipe 107 to cool the coolant in the cavity 103 more effectively, improving the heat dissipation effect.

[0081] It should be noted that since the cavities 103 are interconnected, there is a certain balance between the coolant in the cavities 103. Therefore, temperature sensors 202 can be set at intervals in the cavities 103 to achieve overall cooling of the coolant in the cavities 103. The specific settings can be made according to actual needs.

[0082] Optional, liquid cooling system 200, such as Figure 8 As shown, it also includes:

[0083] Air pump 204;

[0084] At least two pressure sensors 205 are installed in the gas phase zone 206 of different chambers 103 to monitor the gas pressure in each chamber 103. When the gas pressure reaches the preset pressure, the controller increases the exhaust volume of the air pump 204 to discharge the gas in the gas phase zone 206 into the gas-liquid separator 108B of the liquid cooler 100.

[0085] Multiple pressure sensors 205 can be installed in the liquid cooling system 200. One pressure sensor 205 can be installed in the gas phase zone 206 of a cavity 103 to monitor the pressure in the gas phase zone 206 of the cavity 103. During this process, the air pump 204 can exhaust gas to the outside through a certain exhaust volume to maintain the pressure stability of the gas phase zone 206.

[0086] As the external environment changes, the vaporization of the coolant in cavity 103 may increase, leading to a rise in gas pressure in the vapor phase zone 206 and a corresponding increase in the value detected by pressure sensor 205. When the detected pressure reaches a preset pressure (generally set to a value higher than atmospheric pressure), the controller can increase the exhaust volume of air pump 204 (or increase the power of air pump 204) to accelerate the discharge of excess gas in vapor phase zone 206, restoring the pressure in vapor phase zone 206 to a stable level. This prevents damage to the liquid cooler 100 due to excessive pressure in cavity 103 (e.g., the cavity top cover 104), or injury to personnel due to instantaneous pressure leakage when the cavity top cover 104 is opened for ICT equipment maintenance.

[0087] Subsequently, when the pressure sensor 205 detects that the pressure has returned to a stable state, the operation of the air pump 204 can be restored to the preset exhaust volume (or power) to stabilize the pressure in the gas phase zone 206, thereby improving the maintenance efficiency and safety of the liquid cooling system 200.

[0088] The discharged gas enters the gas-liquid separator 108B, where the gas is liquefied to remove excess air. The liquefied coolant can be controlled to continue flowing into the storage tank 108D, and this portion of coolant can be returned to the cavity 103 for replenishment.

[0089] Optional, liquid cooling system 200, such as Figure 9 As shown, it also includes:

[0090] At least two position sensors 207 are provided, with different position sensors 207 being installed on the top cover 104 of the cavity corresponding to different cavities 103. These sensors are used to detect the position of the top cover 104. When the top cover 104 is detected to be open or closed, the controller increases the exhaust volume of the air pump 204 to discharge the gas in the gas phase zone 206 into the gas-liquid separator 108B of the liquid cooler 100.

[0091] The position sensor 207, which can be an infrared sensor, distance sensor, or similar type, is used to determine the positional relationship between the cavity top cover 104 and the cavity 103, thereby determining whether the cavity top cover 104 is open or closed. When the cavity top cover 104 is open, it indicates that maintenance of the ICT equipment 300 is required, and the coolant is in direct contact with the external environment. This process inevitably increases the evaporation of coolant, causing coolant loss. At this time, the controller can control the air pump 204 to increase the exhaust volume, so that the coolant mixed with air evaporated in the gas phase zone 206 is discharged into the gas-liquid separator 108B through the exhaust pipe 108A. The mixed gas is liquefied, the air is discharged, and the coolant is collected and replenished to the cavity 103 through the return pipe 108E, avoiding the waste of coolant vaporization and improving the maintenance efficiency of the liquid cooling system 200.

[0092] Optionally, the gas-liquid separator 108B of the liquid cooler 100 includes an exhaust valve 108C and a liquid level sensor 108F;

[0093] The liquid level sensor 108F is used to detect the liquid level of the coolant in the gas-liquid separator 108B, and when the preset height is reached, the controller opens the exhaust valve 108C to discharge the gas in the gas-liquid separator 108B.

[0094] In the liquid cooling system 200, for the exhaust module 108, the controller can be set to periodically open the exhaust valve 108C to discharge the air (the remaining portion after liquefying the coolant) from the gas-liquid separator 108B. Since the gas-liquid separator 108B is generally closed (to prevent insufficient vaporization of coolant in the incoming mixed gas from overflowing), if the exhaust volume of the air pump 204 increases over a period of time, it may lead to an increase in air and pressure in the gas-liquid separator 108B. At this time, the controller can use the liquid level sensor 108F to detect the liquid level in the gas-liquid separator 108B to determine how much gas has entered the gas-liquid separator 108B. When the liquid level reaches a preset height, it indicates that a large amount of gas has entered the gas-liquid separator 108B and been liquefied into coolant. Correspondingly, a large amount of air is stored in the gas-liquid separator 108B, requiring the exhaust valve 108C to be opened to discharge the air from the gas-liquid separator 108B so that the mixed gas can be discharged into the gas-liquid separator 108B subsequently. In addition, since a large amount of coolant has been stored in the gas-liquid separator 108B, this coolant needs to be discharged into the storage tank 108D for storage, so that it can be pumped back to the cavity 103 of the liquid cooler 100 for replenishment later.

[0095] Optional, liquid cooling system 200, such as Figure 10 As shown, it also includes:

[0096] A steam compressor 201 is installed on the second branch pipe 107A of the liquid cooler 100;

[0097] At least two position sensors 207 are provided, with different position sensors 207 being set on the cavity top cover 104 corresponding to different cavities 103, for detecting the position of the cavity top cover 104. When the cavity top cover 104 is detected to be open, the power of the steam compressor 201 is increased by the controller.

[0098] When the liquid cooling system 200 is operating, if a staff member needs to maintain a particular ICT device 300, the top cover 104 of the chamber needs to be opened. At this time, because the coolant inside the chamber 103 is in direct contact with the outside, the vaporization of the coolant intensifies, causing gas to overflow. The temperature of the still liquefied coolant is very likely to rise, reducing the cooling effect of the coolant on the ICT device 300. At this time, the controller can determine that the top cover 104 of the chamber is open based on the detection of the position sensor 207, control the vapor compressor 201 to increase its power to liquefy the vaporized coolant, and reduce the temperature of the coolant in the second branch pipe 107A, so as to provide stronger cooling for the coolant inside the chamber 103 and avoid the decrease in the cooling effect of the liquid cooling cabinet 100 due to the opening of the top cover 104.

[0099] It should be noted that the above Figures 7 to 10 The various structures described can be implemented individually or in combination, and are not limited to these. Figures 7 to 10 Each figure represents a structural type. For example, an exhaust module 108, a steam compressor 201, and various sensors as needed can be set up separately in the same liquid cooling system 200, depending on the actual situation.

[0100] In this embodiment, a partition is installed in the liquid cooling cabinet to divide the liquid cooling chamber into multiple cavities. Each cavity is used to accommodate one ICT device for liquid cooling heat dissipation. During operation, the vaporized coolant in the cavity can be liquefied through the cooling pipes laid on the top cover of the cavity. When maintenance is required, a single cavity can be opened to operate the ICT device inside, avoiding the problem of having to open the entire liquid cooling cabinet when maintaining one ICT device, which would cause a large amount of coolant to evaporate and be lost. This improves the maintenance efficiency of the liquid cooling system.

[0101] It should be understood that this specification is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope.

[0102] The above description is merely a preferred embodiment of this specification and is not intended to limit this specification.
