Battery Heat Exchange Plate Structure for Impact-Resistant Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery technologies face issues with reliability due to non-uniform heat exchange and potential connection failures between the heat exchange plate and the frame body, leading to reduced sealing performance and increased risk of leakage and damage during external impacts.
Innovation Solution
The battery design incorporates a frame body with a first beam that limits the expansion of the battery cell and a heat exchange plate fixed to both the frame body and the beam, along with a protection plate to stabilize the heat exchange plate and reduce relative movement, enhancing the uniformity of heat exchange and improving the battery's structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the heat exchange plate is fixed only to the frame body, then the structure is simple, but the connection may fail under external impact and sealing performance deteriorates
Solution Approach 1:
The heat exchange plate is merged with both the frame body and the first beam through fixed connections, creating a more robust structural integration that prevents connection failure under external impact while maintaining reasonable structural complexity
Solution Approach 2:
The first beam is designed with a curved configuration that arches over the battery cell, providing structural reinforcement and distributing impact forces more effectively across the heat exchange plate and frame body connection points
2Reliability
If the heat exchange plate is rigidly fixed to improve heat exchange uniformity, then heat exchange uniformity improves, but the risk of connection failure under impact increases
Solution Approach 1:
The protective plate is installed beforehand to cushion and absorb external impacts before they reach the heat exchange plate, preventing connection failure while maintaining the rigid fixed connection needed for uniform heat exchange
Solution Approach 2:
The curved first beam acts as a structural cushion that flexes under impact loads, reducing the transmission of shock forces to the heat exchange plate connections while maintaining heat exchange effectiveness
3Reliability
If the battery cell is allowed to expand freely, then the battery capacity is maximized, but the structural integrity and sealing performance deteriorate
Solution Approach 1:
The frame body is segmented into multiple components including the frame body, first beam, and protective plate, creating a modular structure that can accommodate battery cell expansion while maintaining overall structural integrity and sealing performance
Solution Approach 2:
The structure incorporates dynamic elements that allow controlled movement and expansion accommodation - the curved first beam can flex and the protective plate can move slightly to accommodate battery swelling while maintaining sealing
