Battery Pack Thermal Management Component Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing thermal management components in battery packs have a poor temperature regulation effect due to the impact of the box and external environment on the battery unit, affecting the performance and lifespan of the battery cells.
Innovation Solution
The thermal management component is mounted between the battery unit and the box, creating a distance greater than zero to reduce the impact of the external environment, and is connected to the frame and box through a connecting element, with a temperature-regulating channel and sealed connecting pipes to enhance temperature regulation and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the thermal management component is placed directly against the box bottom wall, then the structural support is maximized, but the temperature regulation effect deteriorates due to external environmental impact
Solution Approach 1:
The patent introduces a heat insulation component as an intermediary between the thermal management component and the box bottom wall. This mediator blocks the direct thermal pathway to the external environment while maintaining structural support, thus resolving the contradiction between structural strength and temperature regulation effectiveness.
2Volume of moving object
If the battery unit is placed close to the box bottom wall, then the space utilization is maximized, but the temperature regulation effect deteriorates
Solution Approach 1:
The heat insulation component serves as a mediator that creates a thermal barrier between the battery unit and the external environment. This allows the battery unit to be positioned optimally for space utilization while the intermediary component ensures effective temperature regulation by blocking harmful thermal pathways.
3Stability of the object's composition
If the box and external environment have direct contact, then the structural integrity is maintained, but the battery unit is adversely affected by external temperature
Solution Approach 1:
The heat insulation component acts as a protective intermediary between the box structure and the external environment. It maintains the structural integrity of the box while blocking the transmission of harmful external temperature variations to the battery unit inside.
