Solution Overview
Problem
Existing battery pack assemblies in vehicles face challenges with complex cooling structures that require large spaces, making water and air cooling channels incompatible, leading to potential short-circuiting and safety issues due to leakage.
Innovation Solution
A tray with integrated flow channels that allow for both water and air cooling modes, featuring a bottom plate with sub-bottom plates and a frame, enabling concise channel arrangement and safe liquid flow, while also providing energy-absorbing capabilities during collisions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If complex cooling water channels or cooling air channels are provided in the cavity, then cooling function is improved, but device complexity and wiring complexity increase
Solution Approach 1:
The patent integrates both water cooling channels and air cooling channels into a unified tray structure. The tray includes a bottom plate with water cooling channels and side walls with air cooling channels, merging two separate cooling systems into one integrated component. This reduces the number of separate parts and simplifies the overall cooling system architecture.
Solution Approach 2:
The tray is designed to perform multiple cooling functions simultaneously - it can provide water cooling through channels in the bottom plate, air cooling through channels in the side walls, or a combination of both. This multi-functional design allows the same structure to serve different cooling needs without requiring separate dedicated structures for each cooling mode.
2Temperature
If water cooling channels are provided, then cooling efficiency is improved, but safety risk increases due to potential leakage causing short-circuit
Solution Approach 1:
The tray is divided into multiple spliced bottom plates that are connected in parallel to multiple flow channels. This segmentation creates isolated cooling zones, so that if leakage occurs in one channel, it is contained and does not affect other channels or the battery assembly. The modular structure limits the propagation of potential leakage issues.
Solution Approach 2:
The tray structure itself acts as an intermediary barrier between the cooling water channels and the battery assembly. The bottom plate with integrated channels provides a protective layer that prevents direct contact between cooling liquid and battery components, reducing short-circuit risk even if leakage occurs.
3Device complexity
If large space cavity is provided for complex cooling channels, then cooling channel accommodation is improved, but volume requirement increases
Solution Approach 1:
The cooling channels are nested within the tray structure itself rather than occupying separate space in the cavity. The water cooling channels are integrated into the bottom plate and air cooling channels into the side walls, allowing the cooling system to be housed within the existing tray volume without requiring additional cavity space.
Solution Approach 2:
Instead of providing cooling channels that occupy horizontal space in the cavity, the patent utilizes the vertical and lateral dimensions of the tray walls themselves. The air cooling channels are formed in the side walls, effectively using the wall thickness as the channel space, thereby eliminating the need for additional cavity volume.

Function Achieved in This Case
The solution reduces the volume requirement for the battery assembly cavity, ensures clear wiring, and prevents short-circuiting in case of leakage, enhancing safety and protecting the battery assembly by allowing liquid to flow outward, while also providing effective heat exchange and collision protection.
Implementation Method 1
flow channels are provided in at least some sub-bottom plates of the plurality of sub-bottom plates, and a battery assembly is suitable for being mounted on a sub-bottom plate in which a flow channel is provided
Implementation Method 2
The tray provided with the flow channels can further implement energy-absorbing crumple at the time of encountering collisions
Implementation Method 3
the tray provided with the flow channels can further implement energy-absorbing crumple at the time of encountering collisions. This may relatively well protect the battery assembly
