Technical Field

[0001] The utility model relates to the technical field of new energy batteries, in particular to a harmonica tube type water cooling plate for a new energy battery pack. Background Art

[0002] The new energy battery tube-wrapped water cooling plate is a heat dissipation device used in new energy battery systems. It is usually composed of a water pipe network and a heat sink, and is used to cool the battery pack to maintain its appropriate temperature during operation. This water cooling plate conducts the heat generated by the battery into the water through water circulation, and then dissipates it to the external environment through the water pipe network. This system can effectively control the battery temperature, improve the efficiency and life of the battery system, and ensure its safety.

[0003] When connecting water pipes, the water pipe joints on the traditional tubular water-cooled plate are mostly fixed on the plate surface. During installation, it is necessary to ensure that the joint positions of the water pipes and the water-cooled plate are completely matched, which limits the flexibility of installation. During the installation process, if the pipeline layout needs to be adjusted or the installation environment is limited, it may cause connection difficulties and even require redesign or replacement of components, increasing the complexity and cost of installation. In addition, since the connection is fixed, once the installation is completed, it becomes difficult to adjust or replace the pipeline layout, and the entire system may need to be disassembled, which increases the time and cost of maintenance and replacement. At the same time, the fixed joint position may also cause stress concentration when the pipeline is connected, increasing the risk of damage and leakage at the pipeline connection, and reducing the reliability and stability of the system.
