Battery Heat Exchange Plate Layout for Uniform Cell Temperature

The heat exchange plate is segmented by partition plates that divide the heat exchange channels into multiple independent series circuits. Each circuit is assigned to specific battery cells, ensuring that heat exchange medium flows sequentially through designated channels rather than distributing uniformly in parallel. This segmentation enables precise control over heat distribution paths, maintaining temperature consistency while preserving manufacturing simplicity.

Different regions of the heat exchange plate are given different functions through the partition plate configuration. The partition plates create localized heat exchange circuits that are optimized for specific battery cell groups. This local quality approach ensures that each region of the battery pack receives appropriate heat management, improving overall temperature consistency without requiring complete redesign of the entire heat exchange system.

The partition plates are designed as simple planar structures that segment the heat exchange plate into distinct regions. Rather than creating complex three-dimensional flow paths, the segmentation is achieved through straightforward plate insertions that guide the heat exchange medium in series through designated channels. This maintains relative structural simplicity while achieving the temperature consistency benefits of series connection.

The partition plates serve multiple functions simultaneously: they act as structural supports, flow path guides, and thermal isolation barriers. By combining these functions into a single component, the overall device complexity is minimized. The partition plates are integrated directly into the heat exchange plate structure, eliminating the need for separate mounting brackets or additional sealing mechanisms.

The heat exchange system is segmented into multiple series circuits, each handling a specific group of battery cells. The heat exchange medium flows sequentially through channels within each circuit, ensuring that all cells in a given circuit receive comparable heat exposure. This segmentation maintains high heat exchange efficiency by keeping flow velocities adequate in each circuit while eliminating the uneven heating problem associated with parallel flow distribution.

The series connection configuration ensures continuous heat exchange action along the entire flow path through each circuit. The heat exchange medium maintains steady flow through successive channels, providing continuous thermal interaction with battery cells along the flow path. This continuous action prevents the intermittent or uneven heating that can occur in parallel systems where flow distribution may be non-uniform.
