AI Technical Summary
Technical Problem
Existing liquid cooling systems are costly, complex in design, difficult to maintain, have high safety and leakage risks, and poor scalability, especially cold plate liquid cooling systems.
Method used
The battery pack adopts an immersion-type internal liquid cooling pipeline design, which allows the cells to be fully immersed in the coolant for heat exchange when the cell temperature rises. The system utilizes the inlet pipe and spray nozzle to achieve efficient heat exchange, and uses nylon corrugated pipes and T-joints to improve system flexibility.
Benefits of technology

Abstract
The utility model discloses a liquid cooling pipeline in an immersed battery pack, which is characterized in that a liquid inlet joint is fixedly mounted on the battery pack, one end of the liquid inlet joint on the inner side of the battery pack is connected with one end of a liquid inlet hose through a first adapter, and the other end of the liquid inlet hose is connected with a liquid inlet main pipeline through a second adapter; the first liquid inlet pipe, the second liquid inlet pipe, the third liquid inlet pipe and the fourth liquid inlet pipe are arranged in parallel, and liquid inlets of the first liquid inlet pipe, the second liquid inlet pipe, the third liquid inlet pipe and the fourth liquid inlet pipe are connected with a plurality of liquid outlets in the liquid inlet main pipeline in a one-to-one correspondence manner; a plurality of spraying openings are uniformly formed in the first liquid inlet pipe, the second liquid inlet pipe, the third liquid inlet pipe and the fourth liquid inlet pipe; and the liquid outlet joint is fixedly arranged on the battery pack. According to the pipeline, when the temperature of the battery cell rises, the battery cell can be completely immersed in cooling liquid, efficient heat exchange is achieved, and the heat dissipation efficiency is far higher than that of a traditional cold plate type battery cell heat dissipation pipeline.
