Battery Cooling Block Layout for Low Pressure Drop Flow

The cooling block is divided into multiple cooling channels (first cooling channel, second cooling channel, third cooling channel) that segment the heat dissipation path. This segmentation allows cooling water to flow through multiple parallel paths, increasing the effective heat dissipation surface area and improving heat dissipation performance for high-capacity batteries without requiring proportionally higher flow rates.

Different regions of the cooling block are designed with different channel configurations to match local heat generation patterns. The first cooling channel is positioned to cool high-heat generation regions, while the second and third channels address other thermal zones. This local optimization ensures efficient heat removal from critical areas without uniformly increasing flow rate across the entire system.

The cooling channels are designed with varying cross-sectional areas along their length, creating a dynamic flow path that adapts to pressure changes. The channel cross-section increases in the flow direction, which reduces flow velocity and pressure drop while maintaining effective heat transfer. This dynamic geometry optimization improves flow rate without significantly increasing structural complexity.

The cooling block utilizes three-dimensional space efficiently by arranging cooling channels at different depths and orientations. The first cooling channel is positioned at a different height than the second and third channels, creating a multi-layered heat dissipation structure. This spatial arrangement reduces flow path length and pressure drop while maintaining comprehensive cooling coverage.
