Description

Technical Field

[0001] This invention relates to the field of liquid cooling equipment technology, and more specifically, to a multi-unit manifold for data center cabinets. Background Technology

[0002] Cold plate liquid cooling cools the main heat-generating components in a server by using a cold plate device. The cold plate device covers the main heat-generating components of the server. Low-temperature coolant flows out from the coolant distribution unit (CDU) and enters the main supply pipe of the manifold. Then, through the supply branch pipe and fluid connection joint, it enters the cold plate device to exchange heat with the heat-generating components and becomes high-temperature coolant. Then, through the return water pipe and fluid connection joint, it enters the return main pipe of the manifold and then enters the CDU to exchange heat and become low-temperature coolant, completing the cycle.

[0003] In related technologies, with the continuous development of computing power technology, the emergence of high-density computing rack products, and the continuous increase in rack power, the number of cables in the racks (such as fiber optic cables required by servers) is gradually increasing, and the pressure on cable management is becoming increasingly greater. The design of the manifold in the rack is gradually becoming an obstacle to cable management. The application of liquid cooling technology has the risk of leakage. The fluid connector on the manifold is a critical node. Usually, the failure of the fluid connector will lead to leakage. At this time, the water circuit of the manifold needs to be disconnected, and all the servers installed on it will not be able to dissipate heat and will not be able to continue operating. In addition, the current rack delivery mode is the whole rack delivery mode, that is, a single rack is a computing power unit, and it is delivered rack by rack. This requires that the single computing power unit can operate independently, that is, each rack needs to have an independent power supply and water supply system. This architecture requires that a manifold must be configured in each rack, which increases costs. Summary of the Invention

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

[0005] Therefore, embodiments of the present invention propose a multi-unit manifold for data center cabinets. The multi-unit manifold for data center cabinets can be flexibly adjusted according to the layout and number of servers without reconfiguring the cooling system, thus reducing production costs. The manifold is also arranged at intervals with the servers, which improves overall security.

[0006] The multi-unit manifold for data center cabinets according to embodiments of the present invention includes:

[0007] A liquid dispenser and a liquid collector are mounted on the side panel of the cabinet. The extension direction of the liquid dispenser is parallel to the extension direction of the liquid collector, which is also the height direction of the cabinet. The liquid distributor has a liquid dispensing outlet, and the liquid collector has a liquid collecting inlet. The liquid dispensing outlet is connected to the cooling inlet of the server inside the cabinet, and the liquid collecting inlet is connected to the cooling outlet of the server inside the cabinet.

[0008] In some embodiments, multiple cabinets are arranged side by side in the width direction of the cabinets, and in two adjacent cabinets, at least one of the liquid dispenser and the liquid collector is installed on a side panel between the two cabinets.

[0009] In some embodiments of the present invention, the multi-unit manifold for a data center cabinet further includes a mounting component for mounting on a side panel of the cabinet. The mounting component has a positioning element adapted to the manifold or the collector so that at least one of the manifold and the collector is connected to the mounting component via the positioning element.

[0010] In some embodiments of the present invention, the multi-unit manifold for a data center cabinet further includes a horizontal pipeline, which includes a supply branch and a return branch. The return branch is connected to the liquid collection inlet for supplying cooling medium to the liquid collector. The supply branch connects the liquid distribution outlet to the cooling system of the server in the cabinet for supplying the cooling medium to the cooling system.

[0011] In some embodiments, the multi-unit manifold for data center cabinets of the present invention further includes a fluid connector, which is disposed at the dispensing outlet and the collecting inlet, and is used to connect to the pipeline. The extension direction of the fluid connector is orthogonal to the height direction of the cabinet.

[0012] In some embodiments, the fluid connector is located on the side of the distributor or collector away from the server inside the rack.

[0013] In some embodiments, the dispenser further has a plurality of liquid supply chambers, the plurality of liquid supply chambers being arranged circumferentially at intervals along the center line of the dispenser, the plurality of liquid outlets being divided into a plurality of outlet groups, an outlet group including a plurality of liquid outlets, and the plurality of liquid outlets in an outlet group being arranged at intervals along the extension direction of the dispenser, the plurality of outlet groups corresponding one-to-one with the plurality of liquid supply chambers.

[0014] In some embodiments, in two adjacent outlet groups of the dispenser, in the extending direction of the dispenser, the dispensing outlet in one outlet group is located between two adjacent dispensing outlets in the other outlet group.

[0015] In some embodiments, an exhaust valve is also included, which is located at the top of the liquid collector and the top of the liquid distributor, and is used to discharge gas from the liquid collector or the liquid distributor.

[0016] In some embodiments, a hand valve is also included, which is connected between the vent valve and the distributor and between the vent valve and the collector, and is used to open or close the vent valve and the distributor and to open or close the vent valve and the collector.

[0017] The beneficial effects of the multi-unit manifold for data center cabinets according to embodiments of the present invention are as follows: Fluid connectors can be designed on multiple sides of the distributor and collector. The distributor and collector can contain main pipelines and horizontal pipelines, connected by flexible hoses. Fluid connectors are installed on the horizontal pipelines for connection to the server's cooling system. The number of horizontal pipelines or fluid connectors installed on a multi-unit distributor / collector corresponds to the number of liquid-cooled servers required in multiple server racks. The multi-unit manifold can adopt a double-sided symmetrical flow channel design, with the left and right sides corresponding to the liquid supply / return interfaces of two cabinets respectively. The internal part of the manifold uses a central diversion baffle to divide the liquid supply chamber into left and right symmetrical liquid supply chambers, while the internal part of the return liquid unit is still a single-chamber design. A manifold is installed on the shared side panel between two racks. The manifold has two main pipes, one for distributing water and one for collecting it. The manifold is mounted on the shared side panel between the two racks (the racks are placed side-by-side with the side panels close together, at the point where the side panels meet on the back of the racks) using mounting components. Alternatively, the manifold can be installed separately. Taking racks A, B, and C as an example: a distributor is installed on the shared side panel (the adjacent side panels) between racks A and B; a collector is installed on the shared side panel between racks B and C; a collector is installed on the other side panel of rack A; and a distributor is installed on the other side panel of rack C. In this case, a single distributor / collector can be used by the racks on the left and right sides respectively. The liquid distributor and the cabinet are fixedly installed using mounting components. The mounting components are rigid installation structures, with one part clipping onto the cabinet frame and connected by threads, and the other part connected to the liquid distributor or collector by threads. The shape can be designed according to the specific cabinet shape. Attached Figure Description

[0023] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] like Figures 1-4 As shown, the multi-unit liquid distributor for data center cabinets in this embodiment of the invention includes a liquid distributor 21 and a liquid collector 22.

[0025] The distributor 21 and the collector 22 are mounted on the side panel 11 of the cabinet 1, with the extension direction of the distributor 21 parallel to the extension direction of the collector 22 (e.g., ...). Figure 1 (in the vertical direction), in the width direction of rack 1 (e.g.) Figure 1 (in the left and right directions) on.

[0026] The distributor 21 has a dispensing outlet, and the collector 22 has a collecting inlet. The dispensing outlet is connected to the cooling inlet of the server in rack 1, and the collecting inlet is connected to the cooling outlet of the server in rack 1. In other words, the dispensing outlet delivers coolant to the cooling components of the server in rack 1 for cooling. After heat exchange with the server, the coolant is discharged through the cooling outlet to the collecting inlet and then through the collector, facilitating further cooling of the coolant after heat exchange, thus enabling the coolant to be recycled.

[0027] Specifically, such as Figures 1-3 As shown, the multi-unit manifold 2 includes a distributor 21 and a collector 22. The multi-unit manifold 2 can be installed on the side panel 11 of the cabinet 1 by screws or the like. The multi-unit manifold 2 and the servers in the cabinet 1 are arranged at intervals in the left and right direction to avoid them being too close together. This can prevent the multi-unit manifold 2 from leaking and affecting the operation of the servers.

[0028] Understandably, depending on the layout of the equipment inside the cabinet 1, the distributor 21 and the collector 22 in the multi-unit liquid distributor 2 can be arranged on the same side panel 11 of the cabinet 1, or they can be arranged on different side panels 11 of the cabinet 1, to suit different application scenarios.

[0029] Optionally, the structures of the liquid separator 21 and the liquid collector 22 are generally the same. Both the liquid separator 21 and the liquid collector 22 are vertically arranged structures. Their cross-sectional shapes can be square, circular, triangular or other shapes. The interiors of the liquid separator 21 and the liquid collector 22 are hollow to allow water to flow. The liquid separator outlet and the liquid collector inlet are arranged on the liquid separator 21 and the liquid collector 22 respectively in the vertical direction.

[0030] Preferably, there can be multiple liquid outlets and liquid collection inlets. Depending on the location and number of servers in the rack, the corresponding liquid outlets and liquid collection inlets can be selected to optimize the overall cooling circuit layout and improve cooling efficiency.

[0031] In some embodiments, multiple cabinets 1 are arranged side by side in the width direction of the cabinet 1, and in two adjacent cabinets 1, at least one of the liquid distributor 21 and the liquid collector 22 is installed on the side panel between the two cabinets 1.

[0032] It is understandable that multiple cabinets 1 are arranged side by side, and in two adjacent cabinets 1, at least one of the liquid dispenser 21 and the liquid collector 22 is installed on the side panel between the two cabinets 1. The liquid dispenser 21 and the liquid collector 22 can be installed on the side panel between two cabinets 1 simultaneously, or in one cabinet 1, the liquid collector 22 and the liquid dispenser 21 can be installed on the left and right side panels respectively.

[0033] Preferably, the liquid dispenser 21 and the liquid collector 22 are installed on the rear wall of the side panel of the cabinet 1, and the extension direction of the liquid dispenser 21 and the extension direction of the liquid collector 22 are consistent with the vertical direction, so as to free up more operating space for the cabinet 1 and facilitate operators to operate the server in front of or behind the cabinet 1.

[0034] In some embodiments of the present invention, the multi-unit liquid distributor for a data center cabinet further includes a mounting component 3, which is used to mount on the side panel 11 of the cabinet 1. The mounting component 3 has a positioning element that is adapted to either the liquid distributor 21 or the liquid collector 22 so that at least one of the liquid distributor 21 and the liquid collector 22 is connected to the mounting component 3 via the positioning element.

[0035] Specifically, such as Figures 1-3As shown, mounting component 3 is a structure used to secure the dispenser 21 and collector 22 to the side panel 11 of the cabinet 1. Mounting component 3 can be made of a rigid material (such as aluminum alloy) to ensure the stability and safety of the dispenser 21 and collector 22 during operation. A positioning element, part of mounting component 3, is used to ensure that the dispenser 21 and collector 22 are correctly mounted on the side panel 11 of the cabinet 1. The positioning element adapts to a specific interface on the dispenser 21 or collector 22, ensuring precise alignment and connection.

[0036] Understandably, the positioning components correspond to the interfaces on the dispenser 21 or collector 22 and are securely connected together by mechanical connections (such as screws, clips, etc.) or other means. This design ensures the correct position and orientation of the dispenser 21 and collector 22 during installation. The mounting component 3 is mounted on the side panel 11 of the cabinet 1 by screws or other fixing methods. The side panel 11 of the cabinet 1 includes holes for adjustment and fixation to allow for fine-tuning during installation.

[0037] In other words, by using the positioning element and mounting component 3, the installation process of the dispenser 21 and the collector 22 becomes simpler and faster. The installer only needs to align the dispenser 21 and the collector 22 with the positioning element and fix them in place according to the predetermined position and orientation.

[0038] In some embodiments of the present invention, the multi-unit manifold 2 for data center cabinet 1 further includes a horizontal pipeline, which includes a water supply branch and a water return branch. The water return branch is connected to the liquid collection inlet for supplying cooling medium to the liquid collector 22. The water supply branch is connected to the liquid distribution outlet and the cooling system of the server in the cabinet 1 for supplying cooling medium to the cooling system.

[0039] It is understandable that the corresponding liquid collection inlet and liquid distribution outlet are arranged as a group, and a group of liquid collection inlet and liquid distribution outlet are connected by a set of horizontal pipelines. That is, the liquid collector 22 and the liquid distributor 21 can be used as the main pipeline for the flow of coolant, and each group of liquid collection inlet and liquid distribution outlet is connected by horizontally arranged branch pipelines.

[0040] Both the water supply branch and the return branch are rigid designs (such as stainless steel pipes). The two ends of the horizontal pipes are fixed to the side wall of the liquid cooling cabinet 1. The fixing method can be threaded connection (such as opening holes in the side wall of the liquid cooling cabinet 1 and designing mounting parts 3 for installation and fixing at both ends of the horizontal pipes. The mounting parts 3 can be thin plates with holes corresponding to the openings in the side wall of the liquid cooling cabinet 1, so that the horizontal pipes can be threaded to the two side walls of the liquid cooling cabinet 1) or snap-fit ​​connection and other detachable connections.

[0041] Among them, the horizontal pipeline connection forms include: connecting with the horizontal branch pipe by means of a hose or transferring through the fluid connector 4. The difference is that when the hose is extended, it is directly connected to the manifold 22, which cannot be easily disassembled and cleaned, while it can be easily disassembled when transferring through the fluid connector 4.

[0042] It should be noted that at least one of the liquid dispenser 21 and the liquid collector 22 is installed on the side panel 11 of the cabinet 1.

[0043] It is understandable that multiple cabinets 1 are arranged side by side, and one of the liquid dispenser 21 and liquid collector 22 can be installed on the left side panel 11 of the cabinet 1, and the other of the liquid dispenser 21 and liquid collector 22 can be installed on the right side panel 11 of the cabinet 1; or, in two adjacent cabinets 1, the liquid dispenser 21 is installed on the side panel 11 of one cabinet 1, and the liquid collector 22 is installed on the side panel 11 of the other cabinet 1; or, in two adjacent cabinets 1, the liquid collector 22 and the liquid dispenser 21 are installed on the side panel 11 of one cabinet 1.

[0044] In other words, such as Figure 4 As shown, multiple cabinets 1 are arranged side by side, and liquid dispensers 21 and liquid collectors 22 are installed on adjacent side panels 11 in two adjacent cabinets 1, and each pair of adjacent cabinets 1 shares one liquid dispenser 21 and one liquid collector.

[0045] It is understandable that, such as Figure 4 As shown, taking two side-by-side cabinets 1 as an example, a multi-unit manifold 2 is installed on the shared side panel 11 between the two cabinets 1. The manifold 22 has two main pipes, one for distributing water and the other for collecting water. The manifold 22 is installed on the shared side panel 11 between the two cabinets 1 via connecting parts (i.e., the two cabinets 1 are placed side by side, with the side panels 11 close together, at the back of the cabinets 1 where the side panels 11 of the two cabinets 1 are close together).

[0046] In other words, this design allows two racks 1 to share a single manifold 22, saving costs. At the same time, since the manifold 22 is installed on the shared side panel 11 rather than inside the rack 1, the rack 1 has more space for cable management. Also, since the manifold 22 is installed outside the rack 1, leakage problems can be controlled outside the rack 1 and will not affect the servers installed inside the rack 1.

[0047] Alternatively, multiple cabinets 1 can be arranged side by side, with the liquid dispenser 21 and the liquid collector 22 respectively arranged on the two side panels 11 of one cabinet 1, and each pair of adjacent cabinets 1 sharing one liquid dispenser 21 or one liquid collector 22.

[0048] As can be understood, taking three cabinets 1 (A, B, and C) as an example, a liquid distributor 21 is installed on the shared side panel 11 (the adjacent side panel 11) between cabinets 1 A and B, a liquid collector 22 is installed on the shared side panel 11 between cabinets 1 B and C, a liquid collector 22 is installed on the other side panel 11 of cabinet A, and a liquid distributor 21 is installed on the other side panel 11 of cabinet C. In this case, a single liquid distributor / collector 22 can be used by the liquid-cooled cabinets 1 on both the left and right sides.

[0049] In some embodiments, the multi-unit manifold for data center cabinets of the present invention further includes a fluid connector 4, which is disposed at the liquid distribution outlet and the liquid collection inlet. The fluid connector 4 is used to connect to the horizontal pipeline, and the extension direction of the fluid connector 4 is orthogonal to the height direction of the cabinet 1.

[0050] It is understandable that, such as Figures 1-3 As shown, the extension direction of fluid connector 4 is orthogonal to the height direction of cabinet 1, that is, fluid connector 4 is horizontally positioned. This facilitates the layout of the piping, allowing the horizontal piping to extend along the width direction of cabinet 1, rather than occupying the vertical space of cabinet 1.

[0051] Each outlet of the distributor 21 is connected to a fluid connector 4. These fluid connectors 4 are responsible for delivering the cryogenic coolant from the distributor 21 into the horizontal piping, and then distributing it to the various servers. Each inlet of the collector 22 is also connected to a fluid connector 4. These fluid connectors 4 are responsible for collecting the high-temperature coolant after heat exchange in the servers and returning it to the CDU through piping. The fluid connectors 4 are connected to the coolant piping via quick couplings or other connection methods, making it quick and easy to connect and disconnect the piping.

[0052] In other words, the design and installation of fluid connector 4 ensures reliable connections and reduces the risk of leakage. The use of fluid connector 4 enhances system scalability. If servers need to be added or removed, piping connections can be quickly adjusted without requiring large-scale modifications.

[0053] In some embodiments, the fluid connector 4 is located on the side of the distributor 21 or collector 22 away from the server inside the cabinet 1.

[0054] It is understandable that, such as Figures 1-3 As shown, the liquid distributor 21 or liquid collector 22 is square in shape. The fluid connector 4 can be arranged on the left or right side wall or the front side wall of the liquid distributor 21 or liquid collector 22 to reduce the space occupied inside the cabinet 1.

[0055] In other words, because fluid connector 4 is positioned away from the server, a leak in fluid connector 4 will not cause coolant to splash directly onto the server, thus reducing the potential damage to the server hardware. Furthermore, because fluid connector 4 is external, leaks are easier to detect. Maintenance personnel can quickly locate and isolate the leak source, preventing further spread.

[0056] It should be noted that, depending on the placement of the multi-unit manifold 2, the number of fluid connectors 4 is compatible with the number of servers in the rack 1. For example, when the multi-unit manifold 2 is placed on one side panel 11, the number of fluid connectors 4 needs to be compatible with the number of servers in two racks 1.

[0057] In some embodiments, the distributor 21 further has a plurality of liquid supply chambers, which are arranged circumferentially at intervals along the center line of the distributor 21. The plurality of liquid outlets are divided into a plurality of outlet groups, and an outlet group includes a plurality of liquid outlets. The plurality of liquid outlets in an outlet group are arranged at intervals along the extension direction of the distributor 21. The plurality of outlet groups correspond one-to-one with the plurality of liquid supply chambers.

[0058] Understandably, when the distributor 21 and the collector 22 are arranged on different side panels 11, one distributor 21 needs to supply liquid to the servers in two racks 1. That is, the left and right sides correspond to the liquid supply / return interfaces of two racks 1, facing the direction of the liquid-cooled racks 1 that need to be connected. The distributor 22 can adopt a double-sided symmetrical flow channel design, with the left and right sides corresponding to the liquid supply / return interfaces of two racks 1. The distributor 21 uses a central diversion baffle to divide the liquid supply chamber into symmetrical independent chambers (i.e., the liquid supply chambers) on the left and right sides, while the return chamber is still a single-chamber design. Through the setting of multiple liquid supply chambers, the distributor 21 can achieve stable water supply to the left and right sides and avoid cross-interference.

[0059] In some embodiments, in two adjacent outlet groups of the dispenser 21, in the extending direction of the dispenser 21, the dispensing outlet in one outlet group is located between two adjacent dispensing outlets in the other outlet group.

[0060] It is understandable that, such as Figures 1-3 As shown, the alternating arrangement of the outlet groups and the spaced arrangement of the dispensing outlets help ensure that the coolant can be more evenly distributed to each server, thereby improving the uniformity of coolant distribution. By alternating the dispensing outlets, the cross-flow and interference of coolant are reduced, which helps to improve cooling efficiency and reduce flow resistance.

[0061] In some embodiments, the multi-unit liquid distributor for data center cabinets of the present invention further includes an exhaust valve 5, which is disposed on the top of the liquid collector 22 and the top of the liquid distributor 21, and is used to discharge gas from the liquid collector 22 or the liquid distributor 21.

[0062] Specifically, such as Figures 1-3 As shown, vent valve 5 is installed on the top of the collector 22 and the distributor 21. Since gas is lighter than liquid, it naturally rises to the top of the container; therefore, installing vent valve 5 at these locations effectively removes gas from the system. Vent valve 5 is used to remove gas from the collector 22 or distributor 21. This gas may be generated during coolant circulation or be residual air in the system during initial startup. Preferably, vent valve 5 is an automatic vent valve.

[0063] Understandably, the design of the vent valve 5 helps prevent air bubbles from forming in the coolant. Air bubbles can interfere with coolant flow and reduce cooling efficiency. By venting the gas, the coolant flows more smoothly, reducing flow resistance and thus improving coolant flow efficiency and cooling effect. Venting the gas also helps prevent system pressure increases caused by gas buildup, thereby protecting the system from the risk of overpressure.

[0064] In some embodiments, the multi-unit manifold for data center cabinets of the present invention further includes a hand valve 6, which is connected between the exhaust valve 5 and the manifold 21 and between the exhaust valve 5 and the manifold 22. The hand valve 6 is used to open or close the connection between the exhaust valve 5 and the manifold 21 and to open or close the connection between the exhaust valve 5 and the manifold 22.

[0065] It is understandable that, such as Figures 1-3 As shown, a manual valve 6 is installed between the automatic vent valve 5 and the manifold 22. That is, the manual valve 6 is installed on the manifold 22, and the automatic vent valve 5 is installed on the manual valve 6. The manifold 22, the manual valve 6, and the automatic vent valve 5 are all detachably installed (such as by threaded connection). A drainage tube 7 is installed above the vent valve 5.

[0066] When the automatic air vent valve 5 is working, the manual valve 6 is in the open position, and the water circuit is connected to the automatic air vent valve 5, so the automatic air vent valve 5 works normally. When the automatic air vent valve 5 is being maintained, the manual valve 6 is closed, the water circuit is disconnected, and the automatic air vent valve 5 can be removed for maintenance, realizing online maintenance of the automatic air vent valve 5; the liquid generated during the air venting process is introduced into the water collection tray of the liquid cooling cabinet 1 by the drainage pipe 7.

[0067] The beneficial effects of the multi-unit manifold for data center cabinets according to embodiments of the present invention are as follows: Fluid connectors 4 can be designed on multiple sides of the liquid distributor 21 and the liquid collector 22. The liquid distributor 21 and the liquid collector 22 can contain main pipelines and horizontal pipelines. The main pipelines and horizontal pipelines are connected by hoses. Fluid connectors 4 are installed on the horizontal pipelines, which can be connected to the server's cooling system. The number of horizontal pipelines or fluid connectors 4 installed on the multi-unit liquid distributor 2 corresponds to the number of liquid-cooled servers required in the multiple racks 1. The multi-unit manifold 2 and the manifold 22 can adopt a double-sided symmetrical flow channel design. The left and right sides correspond to the liquid supply / return interfaces of the two cabinets 1 respectively. The manifold 21 uses a central diversion baffle to divide the liquid supply chamber into left and right symmetrical liquid supply chambers. The return liquid unit is still a single-chamber design. A manifold 22 is installed on the shared side panel 11 between the two racks 1. The manifold 22 has two main pipes, one for distributing water and the other for collecting water. The manifold 22 is installed on the shared side panel 11 between the two racks 1 via mounting components 3 (the two racks 1 are placed side by side, with the side panels 11 close together, at the back of the racks 1 where the side panels 11 of the two racks 1 are close together); or, the manifold 22 can be installed separately. Taking three racks 1 (A, B, and C) as an example, a manifold 21 is installed on the shared side panel 11 (the close side panels 11) between racks A and B, a manifold 22 is installed on the shared side panel 11 between racks B and C, a manifold 22 is installed on the other side panel 11 of rack A, and a manifold 21 is installed on the other side panel 11 of rack C. In this case, a single manifold 22 can be used by the racks 1 on the left and right sides. The liquid distributor 22 is fixedly installed to the cabinet 1 by the mounting component 3. The mounting component 3 is a rigid installation structure. Part of it is clipped onto the frame of the cabinet 1 and connected by threads, and part of it is connected to the liquid distributor 21 or the liquid collector 22 by threads. The shape can be designed according to the specific shape of the cabinet 1.

[0068] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0069] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
