AI Technical Summary

Technical Problem

Existing liquid-cooled heat exchange structures have low heat exchange efficiency and large internal temperature differences in battery packs, which cannot meet the requirements of all operating conditions and result in temperature rise along the flow path of the medium.

Method used

The L-shaped battery heat exchange plate structure, including a harmonica tube, a left current collector, and a right current collector, forms an S-shaped circuit. Through the combined design of the left and right current collectors and the harmonica tube, the bottom and sides of the battery pack are cooled, enhancing the contact between the coolant and the battery and reducing the temperature difference.

Benefits of technology

This achieves uniform temperature inside the battery pack, extends battery life, improves heat exchange efficiency, and enhances the load-bearing capacity of the cold plate.
