Composite Temperature Control Plate With Insulated Mounting Joints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional temperature control plates in battery packs face issues with deformation at joints due to high thermal conductivity leading to unreliable connections and reduced service life, as well as inadequate heat preservation and dissipation performance.
Innovation Solution
A composite temperature control plate is designed with a temperature control layer and a protective layer, including a heat insulating layer and a mounting portion extending to the periphery, which improves connection reliability and enhances heat preservation by using materials like aluminum, glass fibers, and carbon fibers, and a foam layer for better structural support and thermal insulation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the temperature control plate is directly friction welded with other battery pack structures, then connection is achieved, but deformation occurs at the joint leading to shortened service life
Solution Approach 1:
The mounting portion acts as an intermediary element between the temperature control plate and other battery pack structures. It provides a dedicated connection interface that distributes mechanical stresses and prevents direct stress concentration at friction welding joints, thereby preventing deformation and extending service life while maintaining ease of manufacture.
2Ease of operation
If the temperature control plate has direct connection structures, then connection with outside is enabled, but the connection structure is prone to deformation
Solution Approach 1:
The mounting portion extends in a direction perpendicular to the main body of the temperature control plate, creating a three-dimensional structure. This dimensional extension allows the connection function to be separated from the main thermal management function, enabling connection capability while maintaining the structural stability of the temperature control plate's main body through functional separation.
