Battery Pack Cooling Unit Geometry for Dead Space Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge is to enhance the space efficiency of battery packs, particularly in vehicles, where the installation site is narrow and may have convex shapes, leading to inefficiencies due to dead spaces generated between the battery pack and the vehicle's internal components.
Innovation Solution
A battery pack design featuring a cooling unit with convex and concave parts, an electric module with curved surfaces, and a heat transfer member that accommodates cables, allowing for efficient use of space and minimizing dead spaces by integrating with the vehicle's shape.

Engineering Contradiction Analysis
1Area of stationary object
If a conventional battery pack is mounted in a narrow vehicle installation space with convex shapes, then the battery pack can be installed, but dead spaces are generated between the battery pack and the vehicle structure, reducing space efficiency
Solution Approach 1:
The battery pack incorporates convex and concave parts in its cooling unit that correspond to the convex shapes in the vehicle installation space. The convex part of the cooling unit fits into convex portions of the vehicle structure, while concave parts accommodate rounded components, thereby eliminating dead spaces and improving space efficiency through curved surface matching.
2Adaptability or versatility
If the battery pack is designed with a fixed rectangular shape, then manufacturing is simple, but it cannot adapt to varying installation spaces with different shapes and convexities
Solution Approach 1:
The cooling unit is designed with different local geometries - convex parts in specific regions to fit convex vehicle structures, concave parts to accommodate rounded components, and flat parts for battery module mounting. This localized variation in geometry allows the battery pack to adapt to diverse installation spaces while maintaining a relatively simple overall structure.
