Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containerized battery energy storage systems face challenges in servicing liquid cooling units without removing them from the container, leading to increased time and labor costs due to the fixed size of the container and the need to disconnect pipes for maintenance.
Innovation Solution
A liquid cooling unit design with a cabinet that allows servicing in two directions, enabling access to components without removing the unit from the container, featuring a heat dissipation assembly with dual circulation systems and a rotatable electric control component for efficient maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the container size is fixed and batteries are arranged to maximize charging/discharging capacity, then the liquid cooling unit occupies less space and its sides are positioned tightly against the container, but servicing the liquid cooling unit becomes difficult and requires removing connecting pipes and pulling the unit outside the container
Solution Approach 1:
The liquid cooling unit is divided into multiple independent components (compressor, condenser, evaporator, water tank, connecting pipes) that can be accessed and serviced separately through openings in the container wall, allowing maintenance without removing the entire unit from the container
Solution Approach 2:
The cabinet of the liquid cooling unit is made detachable from the container wall, allowing it to be extracted partially for servicing while remaining connected to the battery modules inside the container, thus enabling maintenance without complete removal
2Area of stationary object
If the liquid cooling unit is positioned tightly against the container to maximize battery arrangement, then space utilization is improved, but maintenance time and labor cost increase due to the need to disconnect pipes and remove the unit
Solution Approach 1:
The cabinet is pre-designed with detachable connections to the container wall and built-in openings for component access, so that when maintenance is needed, the cabinet can be quickly removed and components accessed without time-consuming disassembly operations
Solution Approach 2:
The detachable cabinet acts as an intermediary between the fixed container structure and the serviceable components, allowing the unit to maintain tight positioning for space efficiency while enabling quick access to internal components through the detachable design
3Ease of repair
If the liquid cooling unit is designed with components accessible from multiple directions, then servicing becomes easier without removing the unit, but the device complexity increases
Solution Approach 1:
The cabinet is designed with asymmetric opening arrangements tailored to the specific servicing needs of each component, with openings positioned on different sides of the cabinet body according to where the components are located, optimizing accessibility without adding unnecessary structural complexity
Solution Approach 2:
Instead of making the entire unit removable from the container, the design enables access to components through openings in the cabinet walls, transforming the servicing approach from one-dimensional (complete removal) to multi-dimensional (access through various openings), thereby improving accessibility while maintaining compact positioning
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

AI summary
A liquid cooling unit is arranged at an end surface of a casing of a energy storage container. The liquid cooling unit includes a cabinet having an accommodation space and a heat dissipation assembly arranged in the accommodation space. The cabinet includes a first surface adjacent to the end surface and a second surface adjacent to a side surface of the container casing and adjacent to the first surface. The direction in which the first surface faces defines a first servicing direction of the liquid cooling unit, and the direction in which the second surface faces defines a second servicing direction of the liquid cooling unit. The heat dissipation assembly is structured to be serviceable in the first servicing direction and the second servicing direction to realize servicing of most of components of the unit without pulling the unit to outside of the container casing for servicing.
