Battery Pack Cover With Circulative Fluid Channel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs face challenges in efficiently dissipating internal heat generated during recharge and discharge operations, which can reduce battery performance and lifespan.
Innovation Solution
The battery pack incorporates a circulative fluid channel system where a cooling fluid, such as air, water, or refrigerant, flows through a channel between inner and outer covers to absorb and emit heat, enhancing cooling efficiency and allowing for easy maintenance and fluid refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional battery packs are used without a circulative fluid channel system, then the structure is simpler and easier to manufacture, but heat dissipation efficiency is insufficient leading to reduced battery performance and lifespan
Solution Approach 1:
The circulative fluid channel is nested within the cover structure itself, with the channel formed between the inner and outer covers. This integration allows the cooling system to be embedded within the existing battery pack housing without requiring separate external cooling components, thus improving heat dissipation while maintaining manufacturing simplicity
Solution Approach 2:
The cover is designed with dual functionality: it serves as both the protective housing for the battery modules and as the heat dissipation structure through its integrated circulative fluid channel. By merging the structural and thermal management functions into a single component, the system achieves effective cooling without increasing overall device complexity
2Temperature
If the circulative fluid channel is integrated into the cover structure, then cooling efficiency is improved through effective heat dissipation, but the manufacturing process becomes more complex
Solution Approach 1:
The fluid channel is nested between the inner and outer covers during the assembly process. The inner cover is placed within the outer cover, and the channel space is formed by the gap between these two components. This nesting approach allows the cooling channel to be created through assembly rather than complex machining, improving cooling efficiency while maintaining ease of manufacture
Solution Approach 2:
The cover is segmented into an inner cover and an outer cover, with the circulative fluid channel formed in the space between them. This segmentation allows each cover to be manufactured separately using standard processes, then assembled together to form the complete cooling system, thereby achieving effective heat dissipation without significantly complicating the manufacturing process
3Reliability
If a circulative fluid channel system is implemented, then battery performance and lifespan are improved through effective heat management, but the device requires additional components such as fluid tanks and pumps
Solution Approach 1:
The circulative fluid channel is merged with the cover structure, eliminating the need for separate dedicated cooling channels. The cover itself becomes the heat dissipation pathway, allowing the system to achieve improved battery performance and lifespan while minimizing the number of additional components required
