Description

TECHNICAL FIELD

[0001] The application relates to the technical field of data center machine rooms, in particular to a liquid cooling door and a cabinet. BACKGROUND

[0002] With the development of computer and network technology, cabinets have become an important part. The servers, network communication devices and other IT facilities of data centers are developing towards miniaturization, networking and rackization. As a carrier of network devices and server devices in data center machine rooms, the cabinet can dissipate heat when the network devices and server devices generate heat due to work, so the heat dissipation capacity of the cabinet determines the working environment of the computer. At present, the cabinet is generally cooled by a back plate cooling door. However, due to the large size difference between cabinets of different manufacturers, the back plate cooling door also has various sizes, which makes the universality of the back plate cooling door and different cabinets poor, and when the back plate cooling door is locally damaged, it can only be replaced as a whole, which has high maintenance cost. In addition, the back plate cooling door is very heavy, and is inconvenient to install and disassemble. SUMMARY

[0003] The application provides a liquid cooling door and a cabinet. The liquid cooling door comprises a plurality of cooling units. The cooling units can be arranged and combined to form liquid cooling doors of different sizes to adapt to cabinets of different models, improve the universality of the liquid cooling door and the cabinet, and reduce maintenance cost.

[0004] The application provides a liquid cooling door. The liquid cooling door comprises a plurality of cooling units. The cooling units have cooling channels. The cooling units are sequentially arranged to form liquid cooling doors of different sizes.

[0005] In the scheme, the cooling unit has a cooling channel, which can exchange heat with the hot air released by the cabinet to dissipate heat of the cabinet. By increasing or decreasing the number of cooling units, the size of the liquid cooling door can be changed, so that the liquid cooling door can be adapted to cabinets of different models, thereby expanding the application range of the liquid cooling door. For example, the liquid cooling door provided by the application can be used for the modification of old equipment or the modular design of existing customized cabinets and data centers. In the scheme, the size of the cooling unit constituting the liquid cooling door is smaller than the size of the liquid cooling door adapted to the cabinet, so the cooling unit has a smaller volume and mass. Compared with the installation of a liquid cooling door on the cabinet in the prior art, the difficulty of disassembly and installation of the cooling unit is reduced, the installation and disassembly efficiency is improved, manpower and material resources are saved, and the safety of the installation and disassembly process is improved. In addition, when a single cooling unit is damaged, it can be replaced individually, thereby reducing maintenance cost.

[0006] In a possible design, the cooling channel comprises an inlet pipe and an outlet pipe, the inlet pipes of the cooling channels are connected, and the outlet pipes of the cooling channels are connected, so that the cooling units are connected in parallel.

[0007] In this scheme, the cooling units are connected in parallel, the inlet pipes and the outlet pipes are directly connected with the cold source or are connected with the cold source through the upstream inlet pipes and outlet pipes, so that each cooling unit forms a circulation loop with the cold source directly or indirectly. Therefore, the temperature of the cooling liquid in the cooling channel of each cooling unit can be closer to the temperature of the cold source, so that each cooling unit has a larger temperature difference with the hot air blown by the cabinet, and the heat exchange capacity between each cooling unit and the hot air is improved.

[0008] In another possible design, the cooling channel comprises an inlet pipe and an outlet pipe, the inlet pipes and the outlet pipes of adjacent cooling channels are connected, so that the cooling units are connected in series.

[0009] In this scheme, the cooling units are connected in series, and only the outlet pipe of the cooling unit located upstream is connected with the inlet pipe of the cooling unit located downstream, so that the length of the connecting pipeline can be reduced, the connection structure between the cooling units is simplified, and the cost is reduced.

[0010] In a possible design, the cooling channel comprises an inlet pipe, an outlet pipe and a plurality of branch pipes; each branch pipe is connected with the inlet pipe and the outlet pipe.

[0011] In this scheme, the branch pipes are arranged to increase the contact area between the cooling channel and the hot air blown by the cabinet, thereby increasing the heat exchange area between the cooling unit and the hot air, and the heat dissipation efficiency can be improved.

[0012] In a possible design, the cooling unit comprises a heat dissipation fin mounted on the branch pipe.

[0013] In this scheme, the heat dissipation fin mounted on the branch pipe is used for air guiding, so that the hot air of the cabinet uniformly flows through the surface of the branch pipe and exchanges heat. The heat dissipation fin further increases the heat exchange area between the cooling unit and the hot air, and the heat dissipation capacity of the cooling unit can be improved.

[0014] In a possible design, the cooling unit further comprises a detection module, which can issue a warning when the cooling channel leaks cooling liquid.

[0015] In this scheme, the detection module can issue a warning in time when the cooling channel leaks, so as to remind the user to handle and solve the leakage problem in time, minimize the loss of the user, and avoid a large safety accident.

[0016] In a possible design, the detection module is arranged at the bottom of the cooling unit or on the outer wall of the cooling channel.

[0017] In this scheme, the detection module is arranged at the bottom of the cooling unit, and the leaked cooling liquid will all drip downward due to gravity and can all be detected by the detection module to issue a warning to remind the user to solve the leakage problem in time. This scheme can reduce the number of detection modules and save production costs. The detection module includes a tray arranged at the bottom of the cooling unit and a detector. The projections of the liquid inlet pipeline, the liquid outlet pipeline and the branch pipeline at the bottom are covered by the tray. Therefore, the cooling liquid can be caught by the tray as long as there is leakage. The cooling liquid falling into the tray can be detected by the detector and a warning can be issued.

[0018] Alternatively, the detection module can be arranged on the outer wall of the cooling channel. In this scheme, the detection module can be a water immersion sensor. When the cooling channel has cooling liquid leakage, it can be immediately detected by the detection module and a warning can be issued. The response time of the detection module can be shortened, the detection efficiency can be improved, and the related losses and hazards caused by water leakage accidents can be better prevented. The water immersion sensor is widely used in data centers, communication machine rooms, power stations, warehouses, archives and all places that need to be waterproof.

[0019] In a possible design, the cabinet includes a control module. The control module includes a control valve, a temperature sensor and a flow meter. The temperature sensor is configured to detect the temperature of the cooling liquid in the cooling channel. The flow meter is configured to detect the flow rate of the cooling liquid in the cooling channel. The control valve is configured to control the working state of the cooling unit according to the detection results of the temperature sensor and / or the flow meter.

[0020] In this scheme, the flow meter is arranged to facilitate the control module to learn the flow rate of the cooling liquid in the cooling channel. The flow rate of the cooling liquid in the cooling channel can be adjusted by controlling the opening and closing of the control valve or the opening angle of the control valve. The temperature sensor is arranged to facilitate the control module to learn the temperature of the cooling liquid in the cooling channel. When the temperature is too high, the opening angle of the control valve can be increased to increase the flow rate of the cooling liquid in the cooling channel, so as to reduce the temperature of the cooling liquid in the cooling channel. Conversely, when the temperature is too low, the opening angle of the control valve can be reduced or the control valve can be temporarily closed, so as to keep the temperature of the cooling liquid in the cooling channel constant. Therefore, the control module is arranged to adjust the flow rate of the cooling liquid in the cooling channel according to the size of the cabinet load, so as to reasonably distribute the dynamic distribution of the cooling liquid in the cooling channel, thereby achieving the purpose of energy saving.

[0021] In a possible design, the control module is located upstream of each cooling unit along the flow direction of the cooling liquid in the cooling channel.

[0022] In the scheme, the control module is arranged upstream of the cooling units, that is, the cooling liquid from the cooling source first passes through the control module before entering the cooling passages of the cooling units, so that the control module can control the working states of all the cooling units, the number of control modules can be reduced, and the cost can be saved.

[0023] In a possible design, the adjacent cooling units are detachably connected through the connecting pieces.

[0024] In the scheme, the adjacent cooling units are detachably connected through the connecting pieces, so that the stability of the combined cooling units can be improved, the shaking between the cooling units can be reduced, the loosening at the connecting positions of the liquid inlet pipes, the liquid outlet pipes and the branch pipes caused by the shaking between the cooling units can be reduced, and the probability of leakage of the cooling units can be reduced.

[0025] The second aspect of the application provides a cabinet, which comprises a housing and the liquid cooling door described above, and the housing has an opening, and the liquid cooling door is connected with the housing and blocks the opening of the housing.

[0026] In the scheme, each cooling unit constituting the liquid cooling door is connected with the housing, and each cooling unit after being connected with the housing can be used as a door of the cabinet to block the opening, so that the possibility of dust and other impurities entering the interior of the cabinet can be reduced, and the service life of network equipment, server equipment and the like in the interior of the cabinet can be prolonged.

[0027] In a possible design, the cabinet has an air outlet side, and the cooling units are located on the air outlet side of the cabinet.

[0028] In the scheme, the cooling units are arranged on the air outlet side of the cabinet, so that the hot air blown out of the cabinet can be quickly exchanged with the cooling units, and the heat exchange capacity between the cabinet and the cooling units can be improved.

[0029] In a possible design, the cooling units comprise fixing assemblies, and the fixing assemblies are used for detachably connecting with the housing.

[0030] In the scheme, the cooling units are detachably connected with the housing through the fixing assemblies, so that the structure of the cooling units is simplified, the connection of the cooling units with different cabinets can be realized, and thus the application range of the cooling units is expanded. Meanwhile, when the cooling units are damaged, the cooling units can be independently detached, and the maintenance of the cooling units is facilitated.

[0031] It should be understood that the foregoing general description and the following detailed description are only exemplary and cannot limit the application. BRIEF DESCRIPTION OF DRAWINGS

[0052] In order to better understand the technical solutions of the present application, the embodiments of the present application are described in detail below in combination with the drawings.

[0053] In a specific embodiment, the present application is further described in detail below through specific embodiments in combination with the drawings.

[0054] The embodiments of the present application provide a liquid cooling door, such as Figure 1 、 Figure 2As shown, the liquid cooling door includes a plurality of cooling units 1, each cooling unit 1 has a cooling channel 11, and the cooling units 1 are arranged in sequence to form liquid cooling doors of different sizes.

[0055] In this embodiment, the cooling unit 1 has a cooling channel 11, which can exchange heat with the hot air released by the cabinet to dissipate heat. By increasing or decreasing the number of cooling units 1, the size of the liquid cooling door can be changed. In addition, the cooling unit 1 can facilitate the modular design of the data center. The number of cooling units 1 can be increased or decreased according to the size of the opening, so that the liquid cooling door can be adapted to cabinets of different models, thereby expanding the application range of the liquid cooling door. For example, the liquid cooling door provided in the present application can be used for the modification of old equipment or for the modular design of existing custom cabinets and data centers. In this embodiment, the size of the cooling unit 1 that constitutes the liquid cooling door is smaller than the size of the liquid cooling door adapted to the cabinet, so the cooling unit 1 has a smaller volume and mass. Compared with the prior art of installing a liquid cooling door on a cabinet, the difficulty of dismounting and installing the cooling unit 1 is reduced, the installation and dismounting efficiency of the cooling unit 1 is improved, manpower and material resources are saved, and the safety of the installation and dismounting process is improved. In addition, when a single cooling unit 1 is damaged, it can be replaced individually, thereby reducing maintenance costs.

[0056] In addition, the size of the cooling unit 1 can be standardized according to the size of the common cabinet, for example, the width of the cooling unit 1 can be designed as two specifications of 600mm or 400mm, and the thickness can be designed as two specifications of 600mm or 800mm, thereby further improving the adaptability between the cooling unit 1 and different cabinets, and facilitating users to design the size of the cabinet according to actual needs. As shown in the following table, different types of standard cabinets and server cabinets can be obtained by combining 600mm*600mm cooling units 1 and 400mm*600mm cooling units 1 or 600mm*800mm cooling units 1 and 400mm*800mm cooling units 1, thereby improving the adaptability between the cooling unit 1 and different types of cabinets.

[0057]

[0058] Note: The size is length* width* thickness.

[0059] In one embodiment, as shown in Figure 2 The cooling channel 11 includes an inlet pipe 111 and an outlet pipe 112, the inlet pipes 111 of each cooling channel 11 are connected, and the outlet pipes 112 of each cooling channel 11 are connected, so that each cooling unit 1 is connected in parallel.

[0060] In the embodiment, the cooling units 1 are connected in parallel, the inlet pipe 111 and the outlet pipe 112 are directly connected with the cold source or connected with the cold source through the upstream inlet pipe 111 and the outlet pipe 112, so that each cooling unit 1 forms a circulation loop with the cold source directly or indirectly. Therefore, the temperature of the cooling liquid in the cooling channel 11 of each cooling unit 1 can be closer to the temperature of the cold source, so that each cooling unit 1 has a larger temperature difference with the hot air blown by the cabinet, thereby improving the heat exchange capacity between each cooling unit 1 and the hot air.

[0061] In the embodiment, as shown in Figure 1 、 Figure 2 , each cooling unit 1 includes an external interface 15. When the adjacent cooling units 1 are connected in parallel, the external interfaces 15 of the adjacent cooling units 1 can be directly connected, which simplifies the structure of the parallel connection of the cooling units 1. The external interfaces 15 can be connected by a hose or a hard pipe. When the cooling units 1 are expanded in multiple directions by parallel connection, the number of external interfaces 15 can be increased to facilitate the parallel connection between adjacent cooling units 1.

[0062] In addition, the cold source can be externally connected (located outside the cabinet) to further reduce the occupation of the internal space of the cabinet, or the cold source can be built-in in the cabinet to simplify the connection of the pipeline between the cold source and the cooling unit 1.

[0063] In another embodiment, the inlet pipe 111 and the outlet pipe 112 of adjacent cooling channels 11 are connected to connect the cooling units 1 in series.

[0064] In the embodiment, the adjacent cooling units 1 are connected in series, and only the outlet pipe 112 of the upstream cooling unit 1 and the inlet pipe 111 of the downstream cooling unit 1 are connected, thereby reducing the length of the connection pipeline, simplifying the connection structure between the cooling units 1, and reducing the cost. At the same time, the series connection between the adjacent cooling units 1 reduces the number of external interfaces 15 when the adjacent cooling units 1 are connected, and reduces the use of hoses or hard pipes, thereby simplifying the connection structure and saving costs.

[0065] Specifically, as shown in Figure 1 、 Figure 2 , the cooling channel 11 further includes a plurality of branch pipes 113, and each branch pipe 113 is connected with the inlet pipe 111 and the outlet pipe 112.

[0066] In the embodiment, the branch pipes 113 increase the contact area between the cooling channel 11 and the hot air blown by the cabinet, thereby increasing the heat exchange area between the cooling unit 1 and the hot air, and improving the heat dissipation efficiency.

[0067] In the embodiment, the liquid inlet pipe 111 and the liquid outlet pipe 112 can be arranged on the same side of the branch pipe 113, and the two ends of the branch pipe 113 are communicated with the liquid inlet pipe 111 and the liquid outlet pipe 112 respectively, that is, the branch pipe 113 can be bent into a U shape, so as to increase the heat dissipation area of the cooling channel 11 and improve the heat dissipation capacity of the cooling unit 1 while achieving the smallest possible volume of the cooling unit 1.

[0068] Meanwhile, as shown in Figure 1 , each cooling unit 1 can form an independent circulation loop, and the size of the cooling unit 1 is small, so the cooling unit 1 can be used for the modular design of the chilled water distribution unit (CDU) part of the machine room, and can be configured in multiple small units. Or the cooling unit 1 can also be used for the deployment of the node side cooling door.

[0069] More specifically, the cooling unit 1 further comprises heat dissipation fins (not shown in the figure) mounted on the branch pipe 113.

[0070] In the embodiment, the heat dissipation fins mounted on the branch pipe 113 are used for air guiding, so that the hot air of the cabinet uniformly flows through the surface of the branch pipe 113 to exchange heat. The heat dissipation fins further increase the heat exchange area between the cooling unit 1 and the hot air, and can improve the heat dissipation capacity of the cooling unit 1.

[0071] The heat dissipation fins can be made of metal materials, including aluminum heat dissipation fins, stainless steel heat dissipation fins and copper heat dissipation fins, etc. The thermal conductivity coefficient of the metal material is high, which can further improve the heat exchange capacity.

[0072] In the above embodiment, as shown in Figure 2 , Figure 3 , the cooling unit 1 further comprises a detection module 13, which can issue a warning when the cooling channel 11 leaks cooling liquid.

[0073] In the embodiment, the detection module 13 can issue a warning in time when the cooling channel 11 leaks, so as to remind the user to handle and solve the leakage problem in time, minimize the user's loss, and avoid major safety accidents.

[0074] Specifically, as shown in Figure 2 , Figure 3 , the detection module 13 is arranged at the bottom of the cooling unit 1 or on the outer wall of the cooling channel 11.

[0075] In this embodiment, the detection module 13 is located at the bottom of the cooling unit 1. Leaking coolant will drip downwards due to gravity, and will eventually be detected by the detection module 13, which will issue an early warning to remind the user to address the leakage problem promptly. This solution reduces the number of detection modules 13 required, saving production costs. The detection module 13 includes a tray 131 placed at the bottom of the cooling unit 1 and a detector 132. The projections of the inlet pipe 111, outlet pipe 112, and branch pipe 113 at the bottom are all covered by the tray 131. Therefore, any coolant leakage can be caught by the tray 131, and the coolant falling into the tray 131 can be detected by the detector 132, which will issue an early warning.

[0076] In practical use, to further simplify the cabinet structure, the detection module 13 can be located at the bottom of the cooling unit 1, which is the lowest point along the height of the cabinet, such as... Figure 2 , Figure 3 The detection module 13 shown by the dashed line can be omitted. With this design, when the cooling unit 1 located above leaks, the leaking coolant can also be detected by the detection module 13 and an early warning can be issued.

[0077] Alternatively, the detection module 13 can be located on the outer wall of the cooling channel 11. In this embodiment, the detection module 13 can be a water immersion sensor. When coolant leaks from the cooling channel 11, it can be detected immediately by the detection module 13 and an early warning can be issued. This can shorten the response time of the detection module 13, improve detection efficiency, and thus better prevent water leakage accidents from causing related losses and hazards. Water immersion sensors are widely used in data centers, communication equipment rooms, power plants, warehouses, archives, and any other places that require waterproofing.

[0078] More specifically, such as Figure 2 , Figure 4 As shown, the cabinet includes a control module 14, which includes a control valve 141, a temperature sensor 142, and a flow meter 143. The temperature sensor 142 is used to detect the temperature of the coolant in the cooling channel 11, the flow meter 143 is used to detect the flow rate of the coolant in the cooling channel 11, and the control valve 141 is used to control the working state of the cooling unit 1 based on the detection results of the temperature sensor 142 and / or the flow meter 143.

[0079] In the embodiment, the flow meter 143 is arranged to facilitate the control module 14 to learn the flow rate of the cooling liquid in the cooling channel 11, and the control module 14 can adjust the flow rate of the cooling liquid in the cooling channel 11 by controlling the opening and closing of the control valve 141 or the opening angle of the control valve 141, and the temperature sensor 142 is arranged to facilitate the control module 14 to learn the temperature of the cooling liquid in the cooling channel 11, when the temperature is too high, the opening angle of the control valve 141 can be increased to increase the flow rate of the cooling liquid in the cooling channel 11, so as to reduce the temperature of the cooling liquid in the cooling channel 11. Conversely, when the temperature is too low, the opening angle of the control valve 141 can be reduced or the control valve 141 can be temporarily closed, so as to keep the temperature of the cooling liquid in the cooling channel 11 constant. Therefore, the control module 14 is arranged to adjust the flow rate of the cooling liquid in the cooling channel 11 according to the load of the cabinet, so as to reasonably distribute the dynamic distribution of the cooling liquid in the cooling channel 11, thereby achieving the purpose of energy saving.

[0080] In the embodiment, the control valve 141 can be an electromagnetic valve, which is convenient for automatic control, and because the electromagnetic valve is a self-loop, the reaction is more sensitive, and it is not easy to leak after long-term use, thereby improving the use safety of the control valve 141 and further simplifying the structure of the cooling unit 1.

[0081] Specifically, as shown in FIG. 1, the control module 14 is located upstream of each cooling unit 1 along the flow direction of the cooling liquid in the cooling channel 11. Figure 2

[0082] In the embodiment, the control module 14 is arranged upstream of the cooling unit 1, that is, the cooling liquid from the cooling source first passes through the control module 14 before entering the cooling channel 11 of each cooling unit 1, which facilitates the control module 14 to control the working state of all cooling units 1, and can reduce the number of control modules 14 and save costs.

[0083] In the embodiment, the control module 14 can further include an automatic control unit, such as a single-chip microcomputer, which has the advantages of small size, light weight, and low price. The automatic control unit has a set control program inside and can be externally connected to a control panel, so that a user can control the control program of the automatic control unit through the control panel, thereby achieving the purpose of controlling the working state of the cooling unit 1.

[0084] Alternatively, the control module 14 can also be located downstream of each cooling unit 1 along the flow direction of the cooling liquid in the cooling channel 11.

[0085] Specifically, the fixing assembly 12 can be a hinge or a bolt.

[0086] In an embodiment, adjacent cooling units 1 are detachably connected through a connecting piece (not shown in the figure).

[0087] ​In this embodiment, adjacent cooling units 1 are detachably connected by connectors, which can improve the stability of the combined cooling units 1, reduce the shaking between cooling units 1, and reduce the loosening of the connection positions of the inlet pipe 111, outlet pipe 112, and branch pipe 113 caused by shaking between cooling units 1, thereby reducing the probability of leakage of cooling units 1.

[0088] The connector can be a snap-fit ​​structure provided on adjacent cooling units 1. For example, one of the adjacent cooling units 1 is provided with a buckle (not shown in the figure) and the other is provided with a locking position (not shown in the figure). The buckle and the locking position engage to make the adjacent cooling units 1 snap-fit ​​together.

[0089] This application also provides a cabinet, such as Figure 1 , Figure 2 As shown, the cabinet includes a housing (not shown) and a liquid cooling door. The housing has an opening, and the liquid cooling door is connected to the housing and seals the opening of the housing.

[0090] In this embodiment, each cooling unit 1 that makes up the liquid cooling door is connected to the housing. After being connected to the housing, each cooling unit 1 can be used as a door of the cabinet to seal the opening, reduce the possibility of dust and other impurities entering the cabinet, and improve the service life of network equipment, server equipment, etc. inside the cabinet.

[0091] Specifically, the cabinet has an exhaust side, and the cooling unit 1 is located on the exhaust side of the cabinet.

[0092] In this embodiment, the cooling unit 1 is located on the air outlet side of the cabinet, and the hot air blown out by the cabinet can quickly exchange heat with the cooling unit 1, thereby improving the heat exchange capacity between the cabinet and the cooling unit 1.

[0093] like Figure 2 As shown, the cooling unit 1 also includes a fixing component 12, which is used for detachable connection with the housing.

[0094] In this embodiment, the cooling unit 1 is detachably connected to the housing via the fixing component 12, which simplifies the structure of the cooling unit 1 and facilitates its connection with different cabinets, thereby expanding the applicability of the cooling unit 1. Furthermore, when the cooling unit 1 is damaged, it can be easily disassembled independently, facilitating its maintenance.

[0095] In addition, when installing the cooling unit 1, it can be assembled independently from low to high. After assembly, the external interfaces 15 between multiple cooling units 1 can be connected by flexible hoses or rigid pipes.
