Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Condensation water can adhere to the surface of cooling pipes in power storage devices, leading to potential short circuits between adjacent power storage modules.
Innovation Solution
A power storage device design that includes resin members positioned between power storage modules to cover cooling pipes, with upper and lower resin members sandwiching the cooling pipes and supported by reinforcement members, along with a cooling plate and accommodation case to prevent condensation water from reaching the pipe surface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a cooling pipe is used for thermal management, then cooling efficiency is improved, but condensation water adheres to the pipe surface causing short circuit risk
Solution Approach 1:
The resin member serves as an intermediary substance between the cooling pipe and the power storage modules. It covers the cooling pipe surface to prevent condensation water from adhering to the pipe, while allowing the cooling function to operate. This mediator resolves the contradiction by protecting against short circuits without compromising cooling efficiency.
2Reliability
If resin members are added to cover cooling pipes, then short circuit prevention is improved, but device complexity increases
Solution Approach 1:
The resin member is implemented as a thin film or shell that conforms to the cooling pipe surface. This approach provides effective coverage for short circuit prevention while minimizing the added structural complexity and space occupation. The flexible nature of the resin allows it to adapt to the pipe geometry without requiring complex mounting structures.
3Reliability
If resin members are positioned between power storage modules, then condensation water coverage is improved, but space for power storage modules is reduced
Solution Approach 1:
The resin member is positioned in the interstitial space between power storage modules, utilizing the vertical or lateral dimension rather than occupying horizontal space. By covering the cooling pipe in the gap between modules, the design achieves comprehensive condensation water coverage without reducing the volume available for power storage modules.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design effectively prevents condensation water from contacting the cooling pipes, reducing the risk of short circuits and enhancing the reliability and safety of the power storage device.
Implementation Method 1
The surface of a cooling pipe is cold, and therefore, in a power storage device equipped with a cooling pipe, condensation water can adhere to the surface of the cooling pipe
