Description

Technical Field

[0001] This utility model relates to the field of energy storage pipeline technology, and in particular to an energy storage thermal management pipeline. Background Technology

[0002] Energy storage systems refer to technologies and devices that can store energy for release when needed. They play an increasingly important role in power systems, especially in the context of the growing popularity of renewable energy. The design and management of thermal management circuits are also crucial. In electrochemical energy storage systems (such as lithium-ion batteries), the role of thermal management circuits is particularly important. The goal of thermal management is to keep the battery operating temperature within the optimal range in order to extend battery life and improve energy efficiency.

[0003] Currently, thermal management piping in energy storage systems relies on a single fastening method, lacking an anti-loosening mechanism. This makes it prone to leakage under vibration or thermal stress, and disassembly and maintenance are complex and time-consuming. Furthermore, the traditional piping insulation layer design is weak, failing to effectively block external heat conduction and radiation, resulting in coolant temperature being easily affected by the environment, significant heat loss, and impacting system temperature control stability. Therefore, this invention proposes an energy storage thermal management piping system to address the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an energy storage thermal management pipeline.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An energy storage thermal management pipeline includes a heat pipe, which is coiled and tortuous, and has connecting pipes at both ends. A sealing insert is fixed to the front end of the connecting pipe, and connecting sleeves are connected to both ends of the heat pipe. A corresponding external threaded pipe is fixed to the front end of the connecting sleeve, and the sealing insert is located inside the external threaded pipe. An internal threaded sleeve is rotatably connected to the end of the connecting pipe outside the sealing insert, and the external threaded pipe is threaded into the corresponding internal threaded sleeve. The heat pipe includes a cooling inner layer, a heat insulation layer, a protective layer, and a reflective outer layer. The heat insulation layer is located outside the cooling inner layer, the protective layer is located outside the heat insulation layer, and the reflective outer layer is located outside the protective layer.

[0007] Preferably, the cooling inner layer is made of stainless steel, and the heat insulation layer is made of solid glass fiber. The stainless steel cooling inner layer has good fluidity and corrosion resistance, and the solid glass fiber heat insulation layer has high heat insulation performance.

[0008] Preferably, the protective layer is made of polycarbonate, and the reflective outer layer is composed of aluminum foil and polyester film. The polycarbonate protective layer has high wear resistance and high corrosion resistance, and the reflective outer layer composed of aluminum foil and polyester film has high heat resistance and high reflective radiant heat performance.

[0009] Preferably, the connecting sleeve is provided with a plurality of locking blocks on its exterior, the plurality of locking blocks being arranged in a circular array on the exterior of the connecting sleeve, a corresponding slider being provided on the inner side of the locking block, a plurality of sliding grooves corresponding to the slider being provided on the outer side of the connecting sleeve, and an insert shaft passing through the locking block being fixed on the outer side of the slider.

[0010] Preferably, corresponding limiting buckles are provided on both the left and right sides of the locking block, and a plurality of the limiting buckles are arranged in a circular array outside the internal threaded sleeve.

[0011] Preferably, the limiting buckle is rotatably connected to the internal threaded sleeve, and a torsion spring is provided at the junction of the limiting buckle.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The heat pipe and connecting pipe of this utility model adopt a double fixing structure of threaded plug and locking block, which is not only convenient for quick disassembly and maintenance, but also prevents accidental loosening through the limit buckle, ensuring the connection reliability of the pipeline system under complex working conditions. The multi-layer composite structure of the heat pipe makes full use of the material properties, and the winding heat pipe layout and standardized interface design can flexibly adapt to the space requirements of different energy storage systems.

[0014] 2. The stainless steel cooling inner layer of this utility model optimizes the flow efficiency of the coolant, the solid glass fiber insulation layer blocks heat transfer, and the reflective outer layer effectively isolates external radiant heat, achieving a low heat loss and highly stable temperature control effect. The protective layer and the stainless steel inner layer form a double corrosion-resistant barrier, and the aluminum foil reflective layer is resistant to high-temperature environments, enabling the pipeline to maintain structural integrity and functional stability under mechanical impact, chemical corrosion, and extreme temperatures.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A thermal management pipeline for energy storage includes a heat pipe 1, which is coiled and tortuous, and both ends of the heat pipe 1 are provided with connecting pipes 2. A sealing insert 5 is fixed at the front end of the connecting pipe 2. Both ends of the heat pipe 1 are connected with connecting sleeves 3. The front end of the connecting sleeve 3 is fixed with an external threaded pipe 6 corresponding to the sealing insert 5. The sealing insert 5 is located inside the external threaded pipe 6. An internal threaded sleeve 4 is rotatably connected to the end of the connecting pipe 2 outside the sealing insert 5. The external threaded pipe 6 is threadedly connected to the corresponding internal threaded sleeve 4. The two connecting pipes 2 are connected to the heat pipe 1. The sealing insert 5 of the connecting pipe 2 is inserted into the connecting sleeve 3. The internal threaded sleeve 4 at the front end of the connecting pipe 2 is rotated so that the internal threaded sleeve 4 is threadedly tightened on the surface of the external threaded pipe 6, thereby realizing the initial connection between the two connecting pipes 2 and the heat pipe 1.

[0022] The connecting sleeve 3 is provided with several locking blocks 9 arranged in a circular array on the outside of the connecting sleeve 3. A corresponding slider is provided on the inner side of each locking block 9. Several grooves 7 corresponding to the sliders are provided on the outer side of the connecting sleeve 3. A shaft 8 passing through the locking block 9 is fixed to the outer side of the slider. Corresponding limiting buckles 10 are provided on both the left and right sides of each locking block 9. Several limiting buckles 10 are arranged in a circular array on the outside of the internal threaded sleeve 4. The limiting buckles 10 are rotatably connected to the internal threaded sleeve 4, and a torsion spring is provided at the junction of the limiting buckles 10. This completes the connection between the two connecting tubes 2. After the threaded connection with the intermediate heat pipe 1, push the locking blocks 9 on the connecting sleeve 3 toward the inner thread sleeve 4, so that one end of the locking block 9 passes through the corresponding two limit buckles 10. The limit buckles 10 can lock the intermediate locking block 9 back, preventing the two connecting pipes 2 and the heat pipe 1 from accidentally falling off, and strengthening the connection strength between the two connecting pipes 2 and the heat pipe 1. When it is necessary to disassemble the connecting pipe 2, slide the locking block 9 on the sliding shaft 8, so that the locking block 9 is disengaged from the limit buckles 10 on both sides. Then unscrew the outer threaded tube 6 off the inner thread sleeve 4 to release the connection between the connecting pipe 2 and the heat pipe 1.

[0023] The heat pipe 1 includes a cooling inner layer 101, a heat insulation layer 102, a protective layer 103, and a reflective outer layer 104. The heat insulation layer 102 is located outside the cooling inner layer 101, the protective layer 103 is located outside the heat insulation layer 102, and the reflective outer layer 104 is located outside the protective layer 103. The cooling inner layer 101 is made of stainless steel, the heat insulation layer 102 is made of solid glass fiber, the stainless steel cooling inner layer 101 has good fluidity and corrosion resistance, the solid glass fiber heat insulation layer 102 has high heat insulation performance, the protective layer 103 is made of polycarbonate, and the reflective outer layer 104 is composed of aluminum foil and polyester film. The polycarbonate protective layer 103 has high wear resistance and high corrosion resistance, and the aluminum foil and polyester film combined reflective outer layer 104 has high heat resistance and high reflective radiant heat performance.

[0024] The heat pipe 1 significantly improves its performance through the synergistic design of multiple materials. The stainless steel cooling inner layer 101 ensures efficient flow of coolant and is corrosion resistant, the solid glass fiber insulation layer 102 blocks heat conduction, the polycarbonate protective layer 103 resists external mechanical and chemical damage, and the aluminum foil and polyester film reflective outer layer 104 effectively reflects radiant heat and enhances high-temperature resistance. This structure significantly reduces heat loss while maintaining the coolant at a low temperature and extends service life through wear resistance and corrosion resistance. Overall, it achieves efficient and stable thermal management, making it particularly suitable for the demanding requirements of energy storage and industrial scenarios.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
