Solution Overview
Problem
Air-cooled systems for battery packs require significant space and are costly, making them inefficient for heat dissipation in large battery packs used in machines like hydraulic excavators and locomotives, and often necessitate additional holding means.
Innovation Solution
A cooling jacket design featuring flipable halves with a channel for coolant flow, providing efficient heat transfer through stacked jackets between plates, which are connected by mechanical fittings and made of high-temperature resistant materials, allowing liquid coolant to flow in a serpentine manner for effective cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air cooling arrangement is used for heat dissipation of energy storage cells, then heat dissipation function is provided, but space allocation increases and packaging size increases
Solution Approach 1:
The cooling jacket combines multiple functions into a single integrated component: it provides heat dissipation through coolant channels while simultaneously serving as structural support for the energy storage cells. The jacket is formed as a single piece with recesses that receive and support the cells, eliminating the need for separate cooling plates and holding means.
Solution Approach 2:
The cooling jacket performs multiple functions simultaneously: (1) heat dissipation through internal coolant channels, (2) structural support for energy storage cells via integrated recesses, and (3) mechanical coupling between battery modules through protrusion-recess engagement. This multi-functionality reduces the overall number of components and packaging space.
2Temperature
If air cooling arrangement is used for heat dissipation, then cooling function is achieved, but device complexity increases due to additional components
Solution Approach 1:
The cooling jacket merges the cooling function with the structural support function into a single integrated component. The jacket includes internal channels for coolant flow and integrated recesses for cell support, eliminating the need for separate cooling plates, thermal interfaces, and holding means that would be required in a conventional air cooling system.
Solution Approach 2:
The single-piece cooling jacket performs multiple functions: heat dissipation through coolant channels, structural support for cells, and mechanical coupling between modules. This multi-functionality significantly reduces device complexity compared to conventional air cooling systems that require separate components for each function.
3Temperature
If conventional cooling plates are used with energy storage cells, then heat transfer is provided, but additional holding means are required
Solution Approach 1:
The cooling jacket combines the heat transfer function with the cell support function in a single integrated structure. The recesses formed as part of the jacket body directly receive and support the energy storage cells, while the internal channels provide coolant flow for heat dissipation, eliminating the need for separate holding means.
4Temperature
If air cooling system is implemented, then cooling function is provided, but cost increases due to increased components
Solution Approach 1:
The cooling jacket is formed as a single integrated piece that combines cooling channels and cell support structures, reducing the total number of components that need to be manufactured, assembled, and sealed. This integration reduces manufacturing complexity and assembly costs compared to conventional air cooling systems with multiple separate components.
Solution Approach 2:
The multi-functional cooling jacket eliminates the need for separate cooling plates, thermal interfaces, and holding means, reducing both component count and assembly operations. The single-piece construction reduces sealing requirements and assembly steps, leading to lower manufacturing and assembly costs.
