Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate compartments are used for battery module, power module, and temperature control, then functional separation is achieved, but device complexity increases and mounting/maintenance becomes inconvenient
Solution Approach 1:
The patent merges the battery compartment, power compartment, and temperature control compartment into a single integrated cabinet structure. The liquid cooling unit is integrated within the cabinet, with cooling channels directly contacting both battery and power modules. This unified design reduces structural complexity while maintaining functional separation through internal partitioning, making mounting and maintenance more convenient.
2Device complexity
If liquid cooling unit is integrated within the cabinet, then device complexity is reduced, but heat dissipation efficiency may be compromised
Solution Approach 1:
The patent implements local quality by designing separate cooling channels within the liquid cooling unit that are specifically optimized for different components. The cooling system has dedicated channels for battery modules and power modules, with independent inlet and outlet ports for each. This localized cooling approach ensures optimal heat dissipation efficiency for each component while maintaining the integrated cabinet structure.
3Area of stationary object
If cabinet door is used to mount liquid cooling unit, then floor area is reduced, but mounting convenience may be affected
Solution Approach 1:
The patent segments the liquid cooling unit into a modular design that can be independently mounted on the cabinet door. The cooling unit is designed as a separate assembly with standardized mounting interfaces, allowing it to be attached to the cabinet door without affecting the overall cabinet structure. This segmentation enables space-saving vertical mounting while maintaining ease of installation and maintenance through modular replacement.
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 integrated design reduces the floor area and improves heat dissipation efficiency, simplifies the structure, and enhances mounting and maintenance convenience while ensuring safety and ventilation.
Implementation Method 1
When the liquid cooling unit cools the battery module and the power module, a first cooling circulation loop may be formed between the liquid cooling unit and the battery module, and a second cooling circulation loop may be formed between the liquid cooling unit and the power module
Implementation Method 2
a projection of the liquid cooling unit on the cabinet door may overlap at least a part of the cooling area, so that the liquid cooling unit can be cooled by air that enters inside the cabinet through the through hole of the cooling area, and air heated by the liquid cooling unit can also be discharged to the outside of the cabinet through the through hole of the cooling area

AI summary
This application provides an energy storage system. The energy storage system may include a cabinet and a liquid cooling unit. The cabinet may include a cabinet door and a cabinet body that are disposed in a hinged connection manner, and the cabinet door may be opened or closed relative to the cabinet body. The cabinet body may include a battery compartment and a power compartment. A battery module is disposed in the battery compartment, and a power module is disposed in the power compartment. The liquid cooling unit is disposed on a side that is of the cabinet door and that faces the cabinet body. The liquid cooling unit is connected to the battery module through a first liquid outlet pipe and a first liquid return pipe, and the liquid cooling unit is connected to the power module through a second liquid outlet pipe and a second liquid return pipe. In the energy storage system provided in this application, the battery module, the power module, and the liquid cooling unit are all disposed in the cabinet, so that integration of the energy storage system can be effectively improved, and mounting and maintenance efficiency of the energy storage system can be improved.
