Description

Technical Field

[0001] This utility model relates to the field of pipeline maintenance technology, and more specifically, to a rapid maintenance device for energy storage liquid cooling pipelines. Background Technology

[0002] Liquid cooling pipelines are key components in energy storage systems for achieving efficient thermal management. They are primarily responsible for delivering coolant (such as ethylene glycol aqueous solution or deionized water) to the area around the battery modules or cells, dissipating heat through circulation and maintaining the energy storage system within a safe temperature range. Their core function is to ensure the efficiency, safety, and long lifespan of the energy storage system. Especially in high-temperature environments or high-rate charge / discharge scenarios, the thermal management capabilities of the liquid cooling pipelines directly impact the performance of the energy storage system. In large-scale energy storage system clusters with storage capacity of megawatt-hours (MWh) and above, the heat accumulation phenomenon of batteries is more serious, so corresponding thermal management measures are more important. In large-scale energy storage system clusters, the volume of energy storage devices has increased dramatically, which has created sealing and isolation requirements for different structural functional areas. In particular, the sealing damage caused by design features such as drilling holes in the enclosure structure during the liquid cooling pipeline process needs to be addressed specifically.

[0003] While traditional liquid cooling pipelines using fireproof putty for wall penetration treatment have many advantages, they also have some drawbacks. In terms of performance, they have limited durability, are susceptible to damage from external forces, have limited sealing performance, have long curing time, inconsistent environmental performance, and may even produce odors.

[0004] Traditional liquid cooling piping systems typically use drain ports for maintenance of secondary and tertiary piping, which is time-consuming and requires venting and resetting after draining, resulting in significant waste of coolant.

[0005] In large-scale energy storage system clusters, achieving rapid maintenance without losing coolant and causing the liquid cooling system to be taken offline has become a functional requirement. Considering the disassembly and maintenance process after battery failure, how to disassemble the liquid-containing structure of the pipeline network without losing its liquid, so as to avoid additional material loss and labor loss, is a functional component in the liquid cooling pipeline network that can meet the requirements of rapid disassembly and maintenance without affecting the design of the liquid cooling pipeline network components. Utility Model Content

[0006] The technical problem to be solved by this invention is how to quickly maintain a large-scale energy storage system cluster without losing coolant, avoid shutting down the liquid cooling system, and thus avoid additional material and labor losses.

[0007] The technical problem to be solved by this utility model is achieved through the following technical solution: To solve the above-mentioned technical problems, this utility model provides a quick maintenance device for energy storage liquid cooling pipelines, which includes a first quick-connect male connector, a first control switch, a large bolt flange, a locking device, a second quick-connect male connector, a second control switch, and a quick connector. The first control switch is connected to the first quick-connect male connector; one side of the large bolt flange is connected to the first control switch; the locking device is disposed on the other side of the large bolt flange; the second control switch is connected to the second quick-connect male connector; one side of the quick connector is connected to the other side of the large bolt flange, and the other side is connected to the second control switch.

[0008] In a preferred embodiment of the quick maintenance device for the energy storage liquid cooling pipeline provided by this utility model, the quick connector is a quick flange joint and the locking device is a rotary nut.

[0009] In a preferred embodiment of the quick maintenance device for the energy storage liquid cooling pipeline provided by this utility model, the quick connector and the large bolt flange are sealed by a locking sealing device.

[0010] In a preferred embodiment of the rapid maintenance device for the energy storage liquid cooling pipeline provided by this utility model, the locking sealing device is a handcuff-type clamp.

[0011] In a preferred embodiment of the quick maintenance device for the energy storage liquid cooling pipeline provided by this utility model, the first control switch and the large bolt flange, and the quick connector and the second control switch are both connected by threads.

[0012] In a preferred embodiment of the quick maintenance device for the energy storage liquid cooling pipeline provided by this utility model, sealing rings are provided between the first control switch and the large bolt flange, between the locking device and the large bolt flange, between the large bolt flange and the quick connector, and between the quick connector and the second control switch.

[0013] In a preferred embodiment of the rapid maintenance device for the energy storage liquid cooling pipeline provided by this utility model, all the sealing rings are EPDM sealing rings.

[0014] In a preferred embodiment of the rapid maintenance device for the energy storage liquid cooling pipeline provided by this utility model, the surface roughness Ra of the sealing ring is ≤0.6.

[0015] In a preferred embodiment of the rapid maintenance device for the energy storage liquid cooling pipeline provided by this utility model, both the first control switch and the second control switch are valve structures.

[0016] In a preferred embodiment of the quick maintenance device for the energy storage liquid cooling pipeline provided by this utility model, the first quick-plug male connector is integrally formed with the first control switch, and the second quick-plug male connector is integrally formed with the second control switch.

[0017] This utility model has the following beneficial effects: During maintenance, a large bolt flange passes through the wall hole of the energy storage container, and a locking device passes through the wall through the hole, thus clamping the wall sheet metal to form a clamping and sealing structure. The large bolt flange and locking device are tightly connected and fixed to the wall, achieving rapid through-wall sealing. After closing the first and second control switches, the large bolt flange and locking device can be separated. At this time, the liquid at both ends is blocked by the closed control switches, allowing for pipeline separation and rapid disassembly and maintenance of the liquid-cooled pipeline network structure. After the large bolt flange and locking device are separated, an external flange structure can still be used to adapt to the above structure for multiple functions such as liquid injection, liquid drainage, and liquid sampling and testing. This enables rapid maintenance in large-scale energy storage system clusters without loss of coolant, avoiding the shutdown of the liquid-cooled system and preventing additional material and labor losses. It adopts an efficient structure to reduce system downtime, improve equipment utilization, and indirectly reduce energy waste; it provides sealing in different structural areas, reducing the impact of ambient humidity on the internal working environment humidity.

[0025] Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] A quick maintenance device for energy storage liquid cooling pipelines includes a first quick-connect male connector, a first control switch, a large bolt flange, a locking device, a second quick-connect male connector, a second control switch, and a quick connector. The first control switch is connected to the first quick-connect male connector; one side of the large bolt flange is connected to the first control switch; the locking device is disposed on the other side of the large bolt flange; the second control switch is connected to the second quick-connect male connector; one side of the quick connector is connected to the other side of the large bolt flange, and the other side is connected to the second control switch.

[0027] During maintenance, a large bolt flange passes through the wall hole of the energy storage container, and a locking device passes through the wall through the hole, thus clamping the wall sheet metal to form a clamping and sealing structure. The large bolt flange and locking device are tightly connected and fixed to the wall, achieving rapid through-wall sealing. After closing the first and second control switches, the large bolt flange and locking device can be separated. At this time, the liquid at both ends is blocked by the closed control switches, allowing for pipeline separation and rapid disassembly and maintenance of the liquid-cooled pipeline network structure. After the large bolt flange and locking device are separated, an external flange structure can still be used to adapt to the above structure for multiple functions such as liquid injection, liquid drainage, and liquid sampling and testing. This enables rapid maintenance in large-scale energy storage system clusters without loss of coolant, avoiding the shutdown of the liquid-cooled system and preventing additional material and labor losses. It adopts an efficient structure to reduce system downtime, improve equipment utilization, and indirectly reduce energy waste; it provides sealing in different structural areas, reducing the impact of ambient humidity on the internal working environment humidity.

[0028] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. The present invention will be described in detail below with reference to the accompanying drawings and embodiments, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. 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.

[0029] Example 1, please refer to Figures 1 to 3This is a quick maintenance device for energy storage liquid cooling pipelines, comprising a first quick-connect male connector 1, a first control switch 2, a large bolt flange 3, a locking device 4, a second quick-connect male connector 5, a second control switch 6, and a quick connector 7. The first control switch 2 is connected to the first quick-connect male connector 1; one side of the large bolt flange 3 is connected to the first control switch 2; the locking device 4 is disposed on the other side of the large bolt flange 3; the second control switch 6 is connected to the second quick-connect male connector 5; one side of the quick connector 7 is connected to the other side of the large bolt flange 3, and the other side is connected to the second control switch 6. During maintenance, a large bolt flange 3 passes through the wall hole of the energy storage container, and a locking device 4 passes through the wall through the wall hole, thus clamping the wall sheet metal to form a clamping and sealing structure. The large bolt flange 3 and the locking device 4 are tightly connected and fixed to the wall, thereby achieving rapid through-wall sealing. After closing the first control switch 2 and the second control switch 6, the large bolt flange 3 and the locking device 4 can be separated. At this time, the liquid at both ends is blocked by the closed control switches, thereby separating the pipeline and disconnecting the liquid-cooled pipeline structure for rapid disassembly and maintenance. After the large bolt flange 3 and the locking device 4 are separated, the external flange structure can still be used to adapt to the above structure for multiple composite functions such as liquid injection, liquid drainage, and liquid sampling and testing. This enables rapid maintenance in large-scale energy storage system clusters without loss of coolant, avoiding the shutdown of the liquid-cooled system and avoiding additional material and labor losses. It adopts an efficient structure to reduce system downtime, improve equipment utilization, and indirectly reduce energy waste; it provides sealing in different structural areas and reduces the impact of ambient humidity on the internal working environment humidity.

[0030] Furthermore, the quick connector 7 is a quick flange joint, and the locking device 4 is a rotary nut.

[0031] Furthermore, the quick-connect fitting 7 and the large bolt flange 3 are sealed by a locking sealing device 8. In this embodiment, the locking sealing device 8 is a handcuff-type clamp. The handcuff-type clamp has strong clamping force and sealing performance, wide range of adjustability, high durability and fatigue resistance. It can be quickly disassembled and reusable, and can adapt to complex spatial layouts. It also has good disassembly and economy. Using the handcuff-type clamp, the locking device 4 and the large bolt flange 3 can be reliably connected together. A groove can also be added at the connection between the quick-connect fitting 7 and the large bolt flange 3, and an EPDM sealing ring 9 can be placed in the groove to achieve a seal.

[0032] Furthermore, sealing rings 9 are provided between the first control switch 2 and the large bolt flange 3, between the locking device 4 and the large bolt flange 3, between the large bolt flange 3 and the quick connector 7, and between the quick connector 7 and the second control switch 6. In this embodiment, the sealing rings 9 are all EPDM sealing rings 9. The sealing performance between the locking device 4 and the large bolt flange 3 can be adjusted by compressing the EPDM sealing ring 9 through the thread pitch of the locking device 4 on the large bolt flange 3. The compression ratio can be controlled to achieve complete sealing and waterproofing, isolating water vapor and creating a suitable environment for the energy storage battery compartment.

[0033] Furthermore, the first control switch 2 and the large bolt flange 3, as well as the quick-connect fitting 7 and the second control switch 6, are all connected by threads. A threaded connection is used, with an additional EPDM sealing ring 9 added in the middle to improve sealing. The sealing ring 9 is made of EPDM material, which has excellent hydrolysis resistance. The molecular structure of EPDM is mainly composed of ethylene, propylene, and a third monomer (such as ENB), and does not contain easily hydrolyzed groups (such as ester bonds or amide bonds). Therefore, it is not prone to hydrolysis when in contact with water-based coolants (such as deionized water or ethylene glycol aqueous solutions), and can maintain stable physical properties even after long-term immersion.

[0034] Furthermore, the surface roughness Ra of the sealing ring 9 is ≤0.6.

[0035] Furthermore, both the first control switch 2 and the second control switch 6 are valve structures.

[0036] Example 2, as a further optimization of Example 1, in this example, the first quick-connect male connector 1 and the first control switch 2 are integrally formed, and the second quick-connect male connector 5 and the second control switch 6 are integrally formed, thereby reducing the number of parts, reducing assembly difficulty, improving assembly efficiency, and improving the ability to perform rapid maintenance.

[0037] Through a controllable shut-off component, it can centrally recover and treat the coolant, avoiding the risk of leakage and complying with environmental protection and safety regulations; the sealing ring 9 seals and isolates different functional areas of the energy storage system container, so as to keep the humidity of the electrical functional area within the qualified range, thereby safely shutting off and draining the coolant.

[0038] The system uses a controllable threaded nut fastener structure to achieve precise waterproof sealing between the joint and the wall, which can meet the different humidity requirements of different functional areas, avoid the adverse effects of high humidity areas on areas requiring dryness, and prevent the overall structure from failing.

[0039] It allows for the removal and installation of components without draining the coolant, providing greater maintainability, improving coolant efficiency, and reducing time and material losses during draining maintenance.

[0040] Durability design reduces the carbon footprint of spare parts production and transportation. Even under conditions of vibration (such as transporting energy storage containers), tilting (such as bumps in vehicle systems), or low temperatures (such as increased coolant viscosity in environments as low as -40°C), the combination of EPDM sealing ring 9 and threaded nut still achieves good sealing performance.

[0041] The size selection of the quick-connect male connector should be based on the heating power of the battery module and the design temperature difference to determine the required coolant flow rate. The pipe diameter should then be selected based on the flow rate, and it must match the inlet and outlet dimensions of the battery module interface, cooling unit (such as cold plate, heat exchanger) and pump.

[0042] The size selection of handcuff-type clamps is based on quick flange joints and large bolt flanges. They need to meet the requirements of strong clamping force and sealing performance, wide range of adjustability, high durability and fatigue resistance, quick disassembly and reusability, adaptability to complex spatial layouts, and cost-effectiveness.

[0043] The sealing ring 9 must have compression resilience and sealing retention, as well as resistance to chemical corrosion by the medium. It can be selected according to the system operating temperature and environmental factors.

[0044] Rotary nuts must meet corrosion resistance requirements and satisfy salt spray characteristics in different enterprise standards and design environments.

[0045] The valve structure must be able to withstand vibration, low temperature and long service life.

[0046] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.
