Description

Technical Field

[0001] This utility model relates to the field of energy storage container technology, and in particular to a liquid cooling pipeline and an energy storage container. Background Technology

[0002] Currently, with the rise of the new energy industry, the development of energy storage container systems has become a top priority. Conventional container systems integrate packs, electrical cabinets, battery management systems, thermal management systems, and fire protection systems, featuring short integration cycles, high integration levels, and wide applicability.

[0003] However, with the rapid development and application of the energy storage industry, fires involving energy storage container systems frequently occur. This is because energy storage systems undergo electrical energy conversion and chemical processes during operation, generating a large amount of heat. If this heat cannot be dissipated effectively and in a timely manner, the high temperature will accelerate the internal chemical reactions of the battery, creating a vicious cycle that can lead to thermal runaway. Investigations into the causes of these fires reveal that most fires originate from uncontrolled battery thermal management.

[0004] Currently, conventional 5MWh containers use liquid-cooled refrigeration units connected to liquid-cooled piping to cool the entire container system and balance the stack-level temperature. However, current liquid-cooled piping systems have the following problems:

[0005] 1. There are many connectors, resulting in higher costs.

[0006] 2. Due to the use of rigid metal pipes, on-site installation is difficult, time-consuming, and labor-intensive. If there are problems with size or position, it is not easy to correct them, which may eventually lead to the inability to install.

[0007] 3. Long-term use of metal pipes may lead to severe corrosion, necessitating replacement. Utility Model Content

[0008] The purpose of this utility model is to provide a liquid-cooled pipeline and energy storage container that can solve the technical problems of existing liquid-cooled pipelines, such as numerous connectors, high cost, difficult installation, and susceptibility to corrosion.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] This utility model designs a liquid cooling pipeline, including a primary pipeline, a secondary pipeline, and a tertiary pipeline. The primary pipeline is arranged horizontally, and its inlet is connected to a liquid cooling unit. The connection between the primary pipeline and the liquid cooling unit is a flexible hose. The secondary pipeline is connected to the primary pipeline and is perpendicular to it. The tertiary pipeline is connected to the secondary pipeline and is located on the side of the secondary pipeline.

[0011] As a preferred embodiment, the connection between the secondary pipeline and the primary pipeline is made of nylon tubing.

[0012] Furthermore, the secondary pipeline and the nylon tube are an integral structure.

[0013] As a preferred embodiment, the connection between the tertiary pipeline and the secondary pipeline is a corrugated pipe.

[0014] Furthermore, the tertiary pipeline and the corrugated pipe are an integral structure.

[0015] This utility model also designs an energy storage container, including a container body, a liquid cooling unit, and the aforementioned liquid cooling pipeline. The container body has an internally hollow structure. The liquid cooling unit is installed on the side of the container body, and the liquid cooling pipeline is installed inside the container body. The inlet of the liquid cooling pipeline is connected to the liquid cooling unit.

[0016] The beneficial effects of this utility model are:

[0017] This utility model provides a liquid-cooled pipeline and energy storage container. Flexible hoses are installed at the connection between the liquid-cooled pipeline and the liquid-cooled unit to replace rigid metal pipes, increasing corrosion resistance and reducing subsequent maintenance costs. Simultaneously, the connection method between primary, secondary, and tertiary pipelines is changed, making pipeline installation more convenient, achieving lightweight design, reducing assembly tolerances, and saving costs.

[0018] Therefore, this utility model can solve the technical problems of existing liquid cooling pipelines, such as numerous connectors, high cost, difficult installation, and susceptibility to corrosion. Attached Figure Description

[0028] To make the technical problem solved by this utility model, the technical solution adopted, and the technical effect achieved clearer, the technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0029] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., 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 utility model and for simplifying the description, and do not 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 utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Specifically, the terms "first position" and "second position" refer to two different positions.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections or detachable connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] This utility model relates to a liquid-cooled pipeline and an energy storage container. Through lightweight and rational design, it effectively solves the assembly problems caused by tolerances or dimensions between the liquid-cooled pipeline and the container, and reduces costs. It offers higher corrosion resistance and lower subsequent maintenance costs. Reduced assembly tolerances facilitate installation, and the lightweight design saves costs.

[0032] This utility model provides a liquid cooling pipeline, including a primary pipeline 11, a secondary pipeline 12, and a tertiary pipeline 13. The primary pipeline 11 is arranged horizontally, and its inlet is connected to a liquid cooling unit 3. The connection between the primary pipeline 11 and the liquid cooling unit 3 is a flexible hose 14. The secondary pipeline 12 is connected to the primary pipeline 11 and is perpendicular to it. The tertiary pipeline 13 is connected to the secondary pipeline 12 and is arranged on the side of the secondary pipeline 12.

[0033] The connection between the secondary pipeline 12 and the primary pipeline 11 is a nylon tube 15. The secondary pipeline 12 and the nylon tube 15 are an integral structure.

[0034] The connection between the tertiary pipeline 13 and the secondary pipeline 12 is a corrugated pipe 16. The tertiary pipeline 13 and the corrugated pipe 16 are an integral structure.

[0035] This utility model also provides an energy storage container, including a container body 2, a liquid cooling unit 3, and the aforementioned liquid cooling pipeline 1. The container body 2 has an internally hollow structure. The liquid cooling unit 3 is disposed on the side of the container body 2. The liquid cooling pipeline 1 is disposed inside the container body 2, and the inlet of the liquid cooling pipeline 1 is connected to the liquid cooling unit 3.

[0036] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 3 As shown, the liquid cooling pipeline consists of three stages. The inlet of the first-stage pipeline 11, connecting to the liquid cooling unit, uses flexible tubing instead of rigid metal tubing, minimizing assembly tolerances. Even if misalignment occurs in the liquid cooling pipeline outside this stage due to manufacturing errors, it can be corrected here. Furthermore, since the liquid cooling pipeline is pre-installed on each container before the liquid cooling unit is packed, and finally the pipeline is secured, the limited operating space due to the presence of the liquid cooling unit makes standard tightening at the connection points extremely difficult. Using flexible tubing at this point effectively alleviates this problem.

[0038] like Figure 4 As shown, a nylon tube extends from the connection point of the secondary pipeline 12 and the primary pipeline 11 for quick connection, achieving lightweighting and cost savings. The ball valve structure used in conventional metal pipes is eliminated, achieving lightweighting and cost savings.

[0039] like Figure 5 As shown, a corrugated pipe section is press-fitted to the end of the secondary pipe 12, making it an integral part of the tertiary pipe, reducing connection steps and saving costs. The conventional quick-connect adapter structure is eliminated, avoiding the problem of excessive connector usage.

[0040] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
