Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Please refer to Figures 1 and 2. The present application provides a pipeline assembly, including a pipeline connector 1, a drainage device 2 and two or more liquid pipelines; the pipeline connector 1 is arranged between the liquid pipeline and the drainage device 2, and can connect the liquid pipeline and the drainage device 2; the aforementioned liquid pipeline provides a flow channel for the liquid, allowing the liquid to flow along a preset trajectory; the drainage device 2 is used to discharge the drainage to the outside, so that at least part of the liquid in the liquid pipeline can be discharged to the outside.

[0032] In this embodiment, the pipe connector 1 includes a pipe body, a drainage interface 11 and a plurality of pipe interfaces; wherein each pipe interface is formed by extending outward from the pipe body, and the drainage interface 11 is formed by recessing the pipe body. In other words, any pipe interface extends outward from the outer surface of the pipe body to form a tubular connector, and the drainage interface 11 is recessed inward from the outer surface of the pipe body to form a hole-shaped connection hole. The pipe connector 1 uses its multiple pipe interfaces to connect each liquid pipe accordingly, and at the same time, the pipe connector 1 uses the drainage interface 11 to connect the drainage device 2. Generally, any pipe interface can be fixedly connected to the corresponding liquid pipe by welding or the like, or can be detachably connected to the corresponding liquid pipe by threaded connection, snap connection or the like; the drainage device 2 is detachably connected to the drainage interface 11, and the operator can adjust the installation state of the drainage device 2 according to the application scenario of the pipeline assembly. For example, for equipment that needs drainage, the drainage device 2 can be installed on the drainage interface 11, so that the drainage device 2 is connected when drainage is needed, so that the drainage device 2 can discharge liquid to the outside.

[0033] In this embodiment, the liquid pipeline is connected to the pipeline connector 1 through a pipeline interface, which is conducive to simplifying the installation of the liquid pipeline and the pipeline connector 1, and is also conducive to ensuring the connection strength of the liquid pipeline and the pipeline connector 1, so that the pipeline connector 1 is easier to connect with the liquid pipeline of conventional size. In this embodiment, the discharge device 2 is connected to the discharge device 2 through the discharge interface 11, which can compress the installation space of the discharge device 2 on the pipeline connector 1 to a certain extent, which is conducive to the installation, use and maintenance of the discharge device 2, and is conducive to achieving the standardized and orderly distribution of various components at the location of the discharge device 2.

[0034] In summary, the pipeline assembly provided in the present application utilizes a pipeline connector 1 to connect the discharge device 2 and each liquid pipeline; the aforementioned pipeline connector 1 utilizes multiple pipeline interfaces to connect multiple liquid pipelines, so that these liquid pipelines are connected in sequence along a specific trajectory to provide a flow channel for the liquid; the aforementioned pipeline connector 1 uses the discharge interface 11 as the installation interface of the discharge device 2, and the installation relationship between the discharge device 2 and the pipeline connector 1 can be adjusted according to different operational requirements, so that when the liquid pipeline needs to be drained, the discharge device 2 can be used to discharge the liquid outward, wherein the shape structure of the discharge interface 11 is conducive to compressing the installation space of the discharge device 2 on the pipeline connector 1, and is conducive to miniaturizing and modularizing the entire pipeline assembly, thereby simplifying the maintenance process and improving the overall operating efficiency of the pipeline assembly and the products in which it is located.

[0035] The pipeline assembly provided in the present application is further described below in conjunction with the accompanying drawings and implementation methods.

[0036] Referring to Figures 2, 5 and 6, in some embodiments, the pipeline assembly provided in the present application includes a drainage device 2, and a drainage passage is provided inside the drainage device 2. When the drainage device 2 is connected to the pipe connector 1 and the drainage device 2 is in an open state, one end of the drainage passage is connected to the liquid pipe through the pipe connector 1, and the other end of the drainage passage is exposed to the outside or connected to a device that can collect liquid; the aforementioned drainage passage is provided with a one-way valve, and the one-way valve is constructed to open in one direction away from the pipe connector 1, that is, when the drainage device 2 is in an open state, the liquid in the pipe connector 1 can flow outward through the drainage device 2, and the liquid flowing out of the drainage device 2 will not flow back to the pipe connector 1, and foreign matter will not enter the pipe connector 1 from the drainage device 2.

[0037] In some embodiments, the drain device 2 can be used as a plug in addition to draining. For example, one end of the drain device 2 is a drain end and the other end is a plug end, and both the drain end and the plug end can be inserted into the drain interface 11; when the drain end is inserted into the drain interface 11, the drain device 2 in the open state can drain, and when the plug end is inserted into the drain interface 11, the drain device 2 can be used to plug the drain interface 11. It can be seen that in this embodiment, changing the installation angle of the drain device 2 on the pipe connector 1 can change the function of the drain device 2, or realize outward drainage, or plug the drain interface 11.

[0038] In the above embodiment, in order to make the drain device 2 have both draining function and blocking function, the drain device 2 can be designed as follows:

[0039] The drainage device 2 may include a drainage inlet, a drainage outlet and a drainage passage, and the drainage passage connects the drainage inlet and the drainage outlet; the aforementioned drainage inlet passes outward from the end face of the drainage end, and when the drainage end is inserted into the drainage interface 11, the drainage inlet is connected to the pipe connector 1; the aforementioned drainage outlet is located between the drainage end and the plug end, and when the drainage end is inserted into the drainage interface 11, the plug end is outside the pipe connector 1, and the drainage outlet is also outside the pipe connector 1. After opening the drainage device 2, the liquid in the pipe connector 1 can enter from the drainage inlet and flow out from the drainage outlet, and when the plug end is inserted into the drainage interface 11, the drainage end and the drainage inlet are both outside the pipe connector 1, and the drainage outlet is also outside the pipe connector 1, so the plug end can block the drainage interface 11.

[0040] With reference to FIGS. 1 to 4 , in each embodiment provided above, the pipe connector 1 is provided with a drainage interface 11 and a plurality of pipe interfaces, wherein the pipe interface extends outward from the outer surface of the pipe body to form a tubular connector, and the drainage interface 11 is recessed inward from the outer surface of the pipe body to form a hole-shaped connection hole. On this basis, in order to improve the installation characteristics of the pipe connector 1, the drainage device 2 can be designed as a tubular part, and the drainage interface 11 is provided in the middle of the pipe of the drainage device 2; the wall thickness of the middle of the pipe of the aforementioned drainage device 2 is greater than the wall thickness at both ends of the pipe, which is conducive to providing a good setting foundation for the drainage interface 11 in the middle of the pipe of the drainage device 2, and is conducive to improving the installation effect of the drainage device 2 and the drainage interface 11.

[0041] Still referring to FIG. 1 to FIG. 4 , in some of the embodiments provided above, the pipeline assembly provided by the present application further includes a blocking block 3 for sealing and plugging the drainage interface 11; generally, the drainage interface 11 can be set as a threaded interface, and accordingly, the blocking block 3 includes a threaded plunger portion, which is used to detachably seal and plug the threaded interface. When the drainage device 2 is not needed, the operator can use the blocking block 3 to block the drainage interface 11 to prevent leakage.

[0042] The above embodiment uses a separate blocking block 3 to play the role of blocking the drainage interface 11. In other words, the drainage device 2 and the blocking block 3 are two independent parts. The drainage device 2 is used to discharge liquid outward, and the blocking block 3 is used to block the drainage interface 11 of the pipe connector 1. In contrast, the drainage device 2 and its plug end mentioned above have both drainage and blocking functions. The advantage is that drainage and blocking can be achieved separately by simply changing the installation angle of the drainage device 2, without the need to replace parts, without considering the storage problem of multiple parts, and the drainage function and the blocking function can be quickly switched.

[0043] In the above embodiment, the drain interface 11 is set as a threaded interface, on this basis, the drain device 2 may include a threaded connection end and a sealing rubber ring; the aforementioned threaded connection end is used to detachably seal and connect the threaded interface; the aforementioned sealing rubber ring is sleeved on the threaded connection end to improve the sealing performance of the drain interface 11 and the drain device 2. The drain device 2 is threadedly connected to the drain interface 11 and sealed with a sealing rubber ring, which can achieve repeated installation and disassembly, and improve the convenience of maintenance operations.

[0044] With reference to Figures 1, 5 and 6, in some embodiments, the pipe connector 1 is provided with more than two pipe connections, and at least some of the pipe interfaces and the corresponding liquid pipes are mutually sleeved and snap-connected. For example, the pipe connector 1 is provided with two pipe interfaces, and the two pipe interfaces are respectively connected to two liquid pipes. For any pipe interface and the corresponding liquid pipe, the adjacent pipe openings of the two are mutually sleeved, and the adjacent pipe openings of the two are snap-connected by a snap-lock structure, which can improve the connection efficiency of each pipe interface and the corresponding liquid pipe, and is conducive to easily and quickly connecting large-sized liquid pipes through the pipe connector 1.

[0045] As shown in Fig. 5 and Fig. 6, the pipe connector 1 can be provided with three pipe interfaces, and the three pipe interfaces are connected to three liquid pipes respectively; usually, two of the pipe interfaces are located on two opposite sides of the pipe connector 1, and the other pipe interface is on the same side as the drainage interface 11, and both are located on the adjacent sides of the remaining two pipe interfaces. For example, the three pipe interfaces are the first pipe interface, the second pipe interface and the third pipe interface, respectively, the first pipe interface and the second pipe interface are located at the top and the bottom of the pipe connector 1, and the third pipe interface and the drainage interface 11 are both located on the right side of the pipe connector 1. In the above example, the two liquid pipes provided at the first pipe interface and the second pipe interface can be regarded as the main pipes of the pipeline assembly, and the liquid pipe provided at the third pipe interface can be regarded as the branch pipe of the pipeline assembly; the branch pipe and the drainage device 2 are both located on the right side of the pipe connector 1, which is conducive to making the pipeline assembly close to other components and components, and is conducive to improving the integrated distribution characteristics of the pipeline assembly and other components.

[0046] In the above embodiment, the pipe connector 1 can be regarded as a modification of a conventional three-way pipe. For example, the three pipe openings of a common three-way pipe are used as pipe interfaces, and holes are punched on the pipe wall of the three-way pipe to serve as a drainage interface 11. Of course, the three pipe openings of the three-way pipe can also be properly adjusted to enable it to better connect the liquid pipe. It can be seen that the pipeline assembly provided by the present application can reduce the number of adapter components required for the connection structure between the liquid pipe and the liquid pipe, and the liquid pipe and the drainage device 2, thereby reducing the number of connection points of the entire pipeline assembly, reducing the risk of leakage, and to a certain extent improving the integration of the liquid pipe and the drainage device 2, saving installation space, which is conducive to providing more operating space for other components of the product in which the pipeline assembly is located.

[0047] With reference to Fig. 1, Fig. 5 and Fig. 6, in some embodiments, the pipe connector 1 is provided with three pipe interfaces, which are respectively a first pipe interface, a second pipe interface and a third pipe interface; usually, the first pipe interface and the second pipe interface are located at two opposite sides of the pipe connector 1, and the first pipe interface and the second pipe interface are respectively a male head and a female head with buckles, for example, the first pipe interface may include a male head for inserting a corresponding liquid pipe and a first elastic buckle provided on the male head, and the second pipe interface may include a female head for sleeve-mounting a corresponding liquid pipe and a second elastic buckle provided on the female head. Based on the aforementioned settings of the first pipe interface and the second pipe interface, multiple liquid pipes can be connected in series through multiple pipe connectors 1. When connecting the liquid pipes in series, each liquid pipe and the corresponding pipe connector 1 are sleeved with each other and connected by buckles, thereby improving the connection efficiency and reducing the connection difficulty.

[0048] In the above embodiment, the specific shape and structure of the first pipe interface and the second pipe interface are conducive to improving the versatility of the pipeline assembly and the pipeline connector 1 thereof, and improving the installation characteristics of the pipeline assembly.

[0049] Referring to FIG. 1 , on the basis of the above embodiment, the three pipe interfaces of the pipe connector 1 can be connected to three liquid pipes one by one. For the convenience of description, the three liquid pipes can be respectively regarded as the first liquid pipe 41, the second liquid pipe 42 and the third liquid pipe 43. The first liquid pipe 41 and the second liquid pipe 42 are installed on two opposite sides of the pipe connector 1, and can be connected by the pipe connector 1 to form the main pipe of the pipe assembly. At the same time, the third liquid pipe 43 is installed on the pipe connector 1 and is located on the adjacent sides of the first liquid pipe 41 and the second liquid pipe 42, and can be connected by the pipe connector 1 to form a branch pipe of the pipe assembly. Based on the above arrangement, in this embodiment, the pipe of the first liquid pipe 41 serves as the liquid inlet end of the above main pipe, the second liquid pipe 42 serves as the liquid outlet end of the above main pipe, and the first liquid pipe 41 is provided with a switch valve 5, which can cut off the first liquid pipe 41 and other liquid pipes upstream thereof.

[0050] Usually, when it is necessary to use the drainage device 2 to drain liquid, the switch valve 5 can be closed to allow the switch valve 5 to cut off the first liquid pipeline 41 and other liquid pipelines upstream of it, preventing the aforementioned first liquid pipeline 41 from continuing to take in liquid, making it convenient for the drainage device 2 to discharge the liquid that has entered the downstream of the switch valve 5 to the outside.

[0051] In addition, when it is necessary to replace a local structure of the pipeline assembly, the switch valve 5 can be closed to cut off the first liquid pipeline 41 and other liquid pipelines upstream thereof, preventing the first liquid pipeline 41 from continuing to enter the liquid pipeline, and then use the drainage device 2 to drain the liquid, and finally disassemble the pipeline connector 1 and related parts and replace them with new parts. Compared with conventional energy storage liquid cooling pipelines, the setting of the switch valve 5 and the drainage device 2 in the pipeline assembly can reduce the maintenance cost of the drainage device 2, specifically, it can avoid stopping the machine to maintain the drainage device 2.

[0052] In the above embodiment, the second liquid pipeline 42, the third liquid pipeline 43 and the pipeline connector 1 can be regarded as a single cluster pipeline, and the first liquid pipeline 41 can be regarded as a main pipeline arranged upstream of the aforementioned single cluster pipeline. The pipeline assembly can quickly connect multiple groups of single cluster pipelines in series and quickly replace single cluster pipelines.

[0053] In some of the embodiments mentioned above, the discharge device 2 is provided with a discharge inlet, a liquid detector and a limiting boss 31; the discharge inlet and the liquid detector can be arranged at the same end of the discharge device 2; obviously, the discharge inlet is the liquid inlet of the discharge device 2, and the liquid in the pipe connector 1 enters the discharge device 2 from the discharge inlet; the liquid detector is used to detect the water volume or water quality, and can monitor the flow rate or water quality when the pipeline assembly is operating normally or when drainage is required; the limiting boss 31 is used to seal against the outer wall of the pipe connector 1, in other words, when the discharge device 2 is inserted into the discharge interface 11 of the pipe connector 1, the limiting boss 31 is sealed against the outer wall of the pipe connector 1; wherein, the distance between the aforementioned limiting boss 31 and the liquid detector is greater than the distance between the limiting boss 31 and the discharge inlet, and at the same time, the distance between the aforementioned limiting boss 31 and the liquid detector is also greater than the wall thickness of the pipe connector 1.

[0054] In the above embodiments, the liquid detector is helpful to expand the functional characteristics of the pipeline assembly and the product in which it is located, and is helpful to better maintain the operating characteristics of the pipeline assembly and the product in which it is located.

[0055] In the above embodiment, the limiting boss 31 is helpful for quickly locating the installation position of the drain device 2 on the pipe connector 1, ensuring that the operator can quickly and accurately install the drain device 2 and the pipe connector 1, and can assist in achieving the sealed connection relationship between the drain device 2 and the drain interface 11. In addition, the aforementioned limiting boss 31 has a specific relative position relationship with the liquid detector and the drain inlet, and has a specific size relationship with the wall thickness of the pipe connector 1. When the drain device 2 is quickly and accurately located at the pipe connector 1 through the limiting boss 31, the liquid detector can be inserted into the pipe connector 1, ensuring that the liquid detector can monitor the flow characteristics of the liquid in the pipe connector 1 in a timely, efficient and accurate manner; as for the drain inlet, according to the actual spacing between the drain inlet and the limiting boss 31, the drain inlet can be inserted into the pipe connector 1, or placed in the drain interface 11.

[0056] In addition, in some embodiments, the pipeline assembly provided by the present application may further include a filter device, which may be disposed on the pipe connector 1. For example, the filter device includes a filter screen and a mounting portion connected to the filter screen, and the mounting portion is sandwiched between the pipe connector 1 and the liquid discharge device 2. It can be seen that in this embodiment, the filter device can be used to filter the liquid flowing through the pipe connector 1, and the liquid discharge device 2 can simplify the positioning and installation of the filter device in the pipe connector 1, which is conducive to the integrated development of the pipe connector 1 and the various components therein.

[0057] The present application also provides an energy storage liquid cooling pipeline, including the above-mentioned pipeline assembly; referring to Figure 1, the energy storage liquid cooling pipeline includes a plurality of pipe connectors 1, which are connected in series with a plurality of liquid pipes along a preset path to form an energy storage liquid cooling main circuit. Usually, the energy storage liquid cooling main circuit is distributed along a straight line trajectory; in the energy storage liquid cooling pipeline, at least one liquid pipe has a smaller diameter than the remaining liquid pipes connected to the corresponding pipe connector 1, and can be used as an energy storage liquid cooling branch. In other words, each pipe connector 1 is provided with an energy storage liquid cooling branch, and the diameter of the liquid pipe serving as the energy storage liquid cooling branch is smaller than the diameter of the liquid pipe serving as the energy storage liquid cooling main circuit.

[0058] In the above embodiment, the diameter of the liquid pipeline as the energy storage liquid cooling branch is smaller than the diameter of the liquid pipeline as the energy storage liquid cooling main circuit, which can realize the diversion of the liquid in the energy storage liquid cooling main circuit, so that the liquid in the energy storage liquid cooling main circuit flows toward multiple cooling objects, such as batteries, thereby liquid cooling multiple objects to be cooled. In addition, the diameter of the liquid pipeline as the energy storage liquid cooling branch is smaller than the diameter of the liquid pipeline as the energy storage liquid cooling main circuit, which is conducive to improving the installation characteristics of the entire energy storage liquid cooling pipeline, for example, it is conducive to realizing the shuttle arrangement of multiple energy storage liquid cooling branches between several closely arranged objects to be cooled, and it is conducive to reducing the difficulty of positioning and installing each energy storage liquid cooling branch, etc.

[0059] In the above embodiment, the distance between the liquid inlet of each pipe connector 1 and the corresponding energy storage liquid cooling branch is greater than the distance between the liquid inlet of the pipe connector 1 and the corresponding drain device 2. Usually, the vertical distribution of the energy storage liquid cooling main circuit is formed by connecting multiple pipe connectors 1 and multiple liquid pipelines in series. For each pipe connector 1, the installation height of the drain device 2 on the pipe connector 1 is less than the installation height of the energy storage liquid cooling branch on the pipe connector 1, which is conducive to ensuring the drainage effect of the drain device 2.

[0060] In summary, the pipeline assembly and energy storage liquid cooling pipeline provided by the present application optimize the installation relationship of various components including the drainage device 2 and multiple liquid pipelines, reduce the number of adapter components such as the pipeline connector 1, reduce material costs and improve space occupancy, and are conducive to reducing the failure rate introduced by the large number of adapter components. It is beneficial to make the entire pipeline assembly develop towards miniaturization and modularization, which is conducive to simplifying the maintenance process and improving the overall operating efficiency of the pipeline assembly and the products in which it is located.

[0061] The above is a detailed introduction to the pipeline assembly and energy storage liquid cooling pipeline provided by the present application. Specific examples are used in this article to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method of the present application and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
