Description

Technical Field

[0001] This utility model belongs to the field of battery cluster technology, and specifically relates to a battery cluster liquid cooling pipe connection sealing device. Background Technology

[0002] With the rapid development of the new energy industry, battery clusters are increasingly being used in energy storage systems, electric vehicles, and other fields. To ensure the efficient and stable operation of battery clusters, effective heat dissipation management is crucial, and liquid cooling systems, due to their excellent heat dissipation performance, have become the mainstream choice for battery cluster cooling. In liquid cooling systems, the liquid cooling pipe connection sealing device is a key component that ensures the reliable sealing of the coolant circulation path; its performance directly affects the operation of the liquid cooling system and the safety and stability of the battery cluster.

[0003] Under the current technological context, existing sealing devices for liquid cooling pipe connections in battery clusters present several pressing issues. Some traditional sealing devices employ a simple single-ring structure, which, with prolonged use, system vibration, and temperature variations, is prone to wear and aging, leading to decreased sealing performance and an increased risk of coolant leakage. Coolant leakage not only reduces the heat dissipation efficiency of the liquid cooling system, causing excessively high battery cluster temperatures and affecting battery performance and lifespan, but can also trigger serious safety incidents such as short circuits, threatening equipment and personnel safety.

[0004] Therefore, developing a battery cluster liquid cooling pipeline connection sealing device with reliable sealing performance, convenient installation and maintenance, and adaptability to complex working conditions and high-requirement application scenarios is of great practical significance and plays a key role in promoting the sustainable and healthy development of the new energy industry. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a sealing device for connecting liquid-cooled pipes in battery clusters.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a battery cluster liquid cooling pipe connection sealing device, comprising a liquid cooling pipe body, wherein a rotating collar and an outer collar are respectively sleeved at both ends of the liquid cooling pipe body, a threaded post is fixedly installed at one end of the rotating collar, and an internal thread groove is provided on the inner side of the outer collar.

[0007] The inner side of the outer sleeve is filled with a sealing element, and the inner side of the sealing element has an inwardly inclined surface. One end of the rotating sleeve is fixedly bonded to an elastic element located on the surface of the threaded column.

[0008] Preferably, the rotating collar and the liquid cooling pipe are rotatably connected, and the surface of the rotating collar is provided with anti-slip grooves at equal intervals.

[0009] Preferably, an interference fit is fixedly installed at one end of the liquid cooling tube, and the outer diameter of the interference fit is approximately equal to the inner diameter of the liquid cooling tube.

[0010] Preferably, an inner fixing ring is fixedly installed inside the outer ring and sleeved on the surface of the liquid cooling pipe, and the inner fixing ring and the liquid cooling pipe are fixedly connected to each other.

[0011] Preferably, the inner diameter of the threaded post is slightly larger than the outer diameter of the inner fixing ring, and the inner threaded groove and the threaded post are threadedly connected to each other.

[0012] Preferably, an installation cavity is formed between the outer ring and the inner fixing ring, and the installation cavity is used in conjunction with the sealing element for accommodating installation.

[0013] Preferably, one end of the outer ring is formed with a contact end face, which is in contact with the elastic element.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. In this invention, a sealing element is pre-filled on the inner side of the outer ring. Then, the interference fit insert is inserted into the outer ring and pushed to the inside of the liquid cooling tube body, while the threaded post is also advanced to the inner side of the outer ring. When the operator rotates the collar, it continues until one end of the threaded post contacts the sealing element and deforms it. The compressed sealing element fully fills the gap in the mounting cavity, thus providing a reliable seal for the liquid cooling tube body connection. During this process, the interference fit insert ensures the integrity of the connection between the two liquid cooling tube body sections, while the sealing element effectively protects against gaps. Together, they ensure connection strength and sealing performance.

[0016] 2. In this invention, when the threaded column is screwed in to its maximum stroke, the sealing element is deformed under compression, while the elastic element simultaneously abuts against the contact end face, providing additional sealing protection for the gap between the rotating collar and the outer collar. In this embodiment, both the sealing element and the elastic element are made of materials with elastic deformation capabilities, which performs exceptionally well in the scenario of connecting liquid cooling pipes in battery clusters;

[0017] 3. The structural design of this utility model has dual advantages: on the one hand, the modular components enable low-cost and rapid assembly, and the sealing can be completed by simply rotating the rotating collar during operation; on the other hand, the sealing element can be flexibly disassembled. When the sealing performance deteriorates due to repeated compression deformation, it can be directly disassembled and replaced without disassembling the entire pipeline system, effectively restoring the initial sealing effect and taking into account both economy and maintenance convenience.

[0028] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings: Specific Implementation Example 1:

[0031] refer to Figures 1-4 A battery cluster liquid cooling pipe connection sealing device includes a liquid cooling pipe body 1, with a rotating collar 2 and an outer collar 3 respectively sleeved at both ends of the liquid cooling pipe body 1. A threaded post 202 is fixedly installed at one end of the rotating collar 2, and an internal thread groove 302 is opened on the inner side of the outer collar 3.

[0032] The inner side of the outer ring 3 is filled with a sealing element 4, and the inner side of the sealing element 4 forms an inner inclined surface 401. One end of the rotating ring 2 is fixedly bonded with an elastic element 5 located on the surface of the threaded post 202.

[0033] Specifically, this structural design has two advantages: on the one hand, modular components enable low-cost and rapid assembly, and the sealing can be completed by simply rotating the rotating collar 2 during operation; on the other hand, the sealing element 4 can be flexibly disassembled, and when the sealing performance deteriorates due to repeated compression deformation, it can be directly disassembled and replaced without disassembling the entire pipeline system, effectively restoring the initial sealing effect, and taking into account both economy and maintenance convenience.

[0034] The rotating collar 2 is rotatably connected to the liquid cooling tube 1. Anti-slip grooves 203 are evenly spaced on the surface of the rotating collar 2. The rotating collar 2 will rotate on the surface of the liquid cooling tube 1 without interfering with the liquid cooling tube 1 through the rotatable connection. The anti-slip grooves 203 can effectively increase the friction of the surface of the rotating collar 2.

[0035] An interference fitment 201 is fixedly installed at one end of the liquid cooling tube 1. The outer diameter of the interference fitment 201 is slightly equal to the inner diameter of the liquid cooling tube 1. During the assembly of the liquid cooling tube 1, the interference fitment 201 will be inserted from one end of the liquid cooling tube 1 to the other end of the liquid cooling tube 1 to increase the integrity of the connection.

[0036] An inner fixing ring 301 is fixedly installed inside the outer ring 3 and is sleeved on the surface of the liquid cooling tube 1. The inner fixing ring 301 and the liquid cooling tube 1 are fixedly connected to each other. The inner fixing ring 301 will cooperate with the outer ring 3 to realize the connection and installation between the inner fixing ring 3 and the liquid cooling tube 1.

[0037] The inner diameter of the threaded post 202 is slightly larger than the outer diameter of the inner fixed ring 301. The inner threaded groove 302 and the threaded post 202 are threadedly connected to each other. In the threaded connection between the threaded post 202 and the inner threaded groove 302, the inner diameter of the threaded post 202 will not cause abutment and mutual interference with the inner fixed ring 301 after the seal 4 is squeezed and deformed.

[0038] An installation cavity 402 is formed between the outer ring 3 and the inner fixing ring 301. The installation cavity 402 is used to accommodate and install the seal 4. The installation cavity 402 provides an installation cavity for the seal 4, and the seal 4 will fill the installation cavity after being squeezed and deformed. Specific Implementation Example 2:

[0040] One end of the outer ring 3 has a contact end face 501, which is in contact with the elastic element 5. During the assembly of the liquid cooling tubes 1 at both ends, the contact end face 501 at the end of the outer ring 3 is in contact with the elastic element 5 at the end of the rotating collar 2, thereby providing a further sealing guarantee at the interface.

[0041] The working principle of this utility model is as follows: During the assembly and connection of two liquid-cooled tube sections 1, the rotating collar 2 is first aligned with the outer collar 3. At this point, the inner side of the outer collar 3 is pre-filled with a sealing element 4. Then, the interference fit insert 201 is inserted into the outer collar 3 and pushed to the inner side of the liquid-cooled tube section 1. Simultaneously, the threaded post 202 is also advanced to the inner side of the outer collar 3. When the operator rotates the rotating collar 2, the anti-slip groove 203 on its surface effectively increases friction, preventing slippage. During rotation, the threaded post 202 and the internal thread groove 302 are connected by threads and advanced to the inner side of the outer collar 3 until one end of the threaded post 202 contacts the sealing element 4 and deforms it. After being compressed, the sealing element 4 fully fills the gap in the installation cavity, thus providing a reliable seal for the connection of the liquid-cooled tube section 1.

[0042] After the threaded post 202 is screwed into the maximum range of its movable movement, the seal 4 is compressed and deformed, and the elastic element 5 also comes into contact with the contact end face 501, providing further sealing protection for the gap between the rotating collar 2 and the outer collar 3. In this embodiment, both the seal 4 and the elastic element 5 are made of rubber, but are not limited to polytetrafluoroethylene, polyurethane, silicone rubber, etc.

[0043] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
