Detachable Cooling Module for Vehicle Battery Thermal Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery modules for vehicles lack flexibility in temperature management, as integrated cooling and heating devices often inadequately address the thermal requirements of different vehicle types, and are difficult to replace or customize.
Innovation Solution
A battery module design where the cooling and heating device is a separate, detachable module that can be fixed to the housing, allowing for selection and replacement based on vehicle type, with a heat transfer element providing defined thermal properties and improved heat conduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the cooling and heating device is integrated into the battery module housing, then the structure is compact and simple to manufacture, but the flexibility and adaptability to different vehicle types is reduced
Solution Approach 1:
The cooling and heating device is segmented from the battery module housing, forming a separate, detachable module. This allows the housing to be manufactured independently and simply, while the cooling/heating module can be independently optimized and selected based on different vehicle type requirements, thus resolving the contradiction between manufacturing simplicity and adaptability.
Solution Approach 2:
The cooling and heating module is designed to be dynamically configurable - it can be attached or detached from the housing depending on the vehicle type and thermal management requirements. This dynamic configuration enables the system to adapt to different applications while maintaining a simple base housing structure.
2Stability of the object's composition
If the cooling and heating device is permanently integrated into the housing, then the assembly is structurally stable, but the ease of replacement and maintenance is reduced
Solution Approach 1:
By segmenting the cooling and heating device as a separate module that can be detachably fixed to the housing, the invention maintains structural stability during operation while enabling easy removal and replacement when defective or when upgrading to different vehicle configurations, thus resolving the contradiction between stability and ease of repair.
3Adaptability or versatility
If the housing and cooling heating device are manufactured separately, then the flexibility and customization options increase, but the device complexity and assembly requirements increase
Solution Approach 1:
The detachable fixing mechanism is designed with universal applicability, using standardized connection interfaces that can accommodate different cooling and heating module configurations. This universal design enables flexibility in selecting different thermal management solutions while keeping the assembly process relatively simple and standardized.
