Hybrid and electric vehicles require an efficient cooling system for their electrical energy storage to prevent overheating, and existing solutions are not simple or compact enough for easy integration with cooling circuits.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the inlet and outlet of the cooling channel system are arranged on the heat sink, then the cooling function is effective, but the connection to the cooling circuit becomes complex and space-consuming
Solution Approach 1:
The inlet and outlet of the cooling channel system are relocated from the heat sink plane to the compression plate level, representing a dimensional shift in the cooling circuit connection interface. This allows cell modules to be arranged in rows with simplified connections to the cooling circuit, resolving the contradiction between effective cooling and connection complexity
2Temperature
If the inlet and outlet are arranged on the heat sink, then cooling is effective, but cell modules cannot be easily aligned and connected in rows
Solution Approach 1:
By moving the cooling circuit connection interface from the heat sink to the compression plate, the system enables straightforward row-wise alignment of cell modules. The upper-level connection points facilitate easier installation and maintenance operations while preserving effective heat dissipation through the heat sink
3Volume of moving object
If a compact housing is used, then space is optimized, but access to inlet and outlet for connection becomes difficult
Solution Approach 1:
The cooling circuit connection interface is positioned at the upper compression plate level, which provides accessible connection points even in compact housings. This dimensional relocation allows maintenance and connection operations to be performed easily without requiring excessive housing volume
