Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a reducing connector for energy storage liquid cooling pipes. Background Technology

[0002] With the rapid development of renewable energy and the increasing global emphasis on carbon emission limits, the importance of energy storage technology, especially large-scale energy storage systems (such as industrial and commercial systems and large-scale pipeline systems), is becoming increasingly prominent. In these systems, thermal management is a key factor in ensuring efficient battery operation and extending battery life. Currently, many energy storage systems employ a three-stage pipeline design to circulate coolant and maintain cell temperatures within an ideal range. However, this design typically supports only one type of inner diameter pipeline, leading to technical challenges when raising thermal management standards.

[0003] Specifically, in pursuit of stricter thermal management requirements, the goal is to minimize the temperature difference between battery cells to ensure the performance consistency and safety of the entire battery pack. However, a single-diameter piping design struggles to meet the coolant flow requirements of battery packs at different locations, especially in vertically arranged battery modules. Due to the pressure drop in the water system, the inflow rate to each battery pack layer fluctuates significantly, typically with the largest flow deviation between the highest and lowest vertical battery pack layers. This uneven cooling effect not only affects the overall heat dissipation efficiency of the battery pack but can also lead to localized overheating, thus threatening the stability and safety of the system. Utility Model Content

[0004] Based on this, in order to solve the problem in the prior art that the large flow deviation between different battery packs leads to different cooling effects, this utility model provides a variable diameter connector for energy storage liquid cooling pipes.

[0029] The thickness of the inner opening 302 is the same as the thickness of the rotary chuck 2, and the depth of the inner opening 302 is 2 / 3 of the height of the rotary joint 3. The inner opening 302 is provided with a protruding triangular prism-shaped protrusion 3021.

[0030] Furthermore, the rotary joint 3 aligns with the elongated triangular groove 202 via the triangular prism-shaped protrusion 3021 and slides into the rotary chuck 2;
