AI Technical Summary

Technical Problem

The coolant temperature in existing immersion liquid cooling technology is uneven, resulting in uneven heat dissipation of the battery.

Method used

A liquid separation tube and liquid separation hole design is adopted. The liquid separation holes are spaced apart along the length of the liquid separation tube. The diameter of the first liquid separation hole is smaller than that of the second liquid separation hole. The coolant flows faster from the liquid inlet and decreases farther away from the liquid inlet, ensuring that the coolant is evenly distributed to the battery module.

Benefits of technology

The coolant is evenly distributed within the battery module, which improves heat dissipation uniformity and heat exchange efficiency and extends the service life of the battery.
