Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage systems face inefficiencies in the removal and mounting of batteries and their heat exchange units due to the need for time-consuming coolant drainage and refilling during maintenance or transportation, leading to high labor intensity and increased costs.
Innovation Solution
The implementation of a self-sealing joint unit in the heat exchange system allows for the heat exchange units to be disconnected without discharging the coolant, simplifying the removal and mounting processes by using a self-sealing joint that maintains the coolant within the system during disassembly and assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional cooling pipelines are used in energy storage systems, then heat exchange function is provided, but removal and mounting work requires time-consuming coolant drainage and refilling
Solution Approach 1:
The cooling system is divided into modular cooling units, each with independent quick-connecting cooling pipelines. This segmentation allows individual cooling units to be removed or mounted without affecting the entire cooling system, enabling coolant to remain in the system while facilitating maintenance operations.
Solution Approach 2:
The cooling pipelines are designed with dynamic quick-connecting structures that enable rapid connection and disconnection. This dynamic design allows operators to quickly assemble or disassemble cooling units without manual draining or refilling operations, significantly reducing maintenance time.
2Ease of repair
If cooling pipelines are connected to main liquid coolant pipeline, then heat exchange is enabled, but repair and replacement work becomes complex
Solution Approach 1:
The cooling system is segmented into independent cooling units with self-contained cooling pipelines. Each unit can be repaired or replaced independently by simply disconnecting the quick-connect interfaces, without requiring complex system disassembly or coolant drainage procedures.
Solution Approach 2:
The quick-connecting cooling pipeline design enables maintenance personnel to perform repair and replacement operations independently without requiring specialized equipment or procedures for coolant drainage and refilling, making the system self-maintainable.
3Productivity
If heat exchange medium port is connected to main heat exchange medium pipeline, then heat exchange function is provided, but disassembly requires heat exchange medium discharge
Solution Approach 1:
The heat exchange medium pipeline incorporates dynamic quick-connecting structures that maintain sealing during connection and disconnection operations. This allows the heat exchange medium to remain contained in the system while enabling rapid assembly and disassembly of heat exchange units without discharge or refilling operations.
Solution Approach 2:
The quick-connecting structure acts as an intermediary mechanism between the heat exchange unit and the main pipeline. It provides a sealed interface that allows for easy connection and disconnection while preventing heat exchange medium leakage, thereby simplifying maintenance operations.

Function Achieved in This Case
This design reduces the time and labor required for battery replacement and transportation by eliminating the need for coolant discharge and refill, enhancing work efficiency and reducing system weight.
Implementation Method 1
the self-sealing joint unit can be mainly operated when the heat exchange unit is disconnected from the main heat exchange medium pipeline. In addition, due to a self-sealing effect of the self-sealing joint unit, the heat exchange medium does not flow out
