Solution Overview
Problem
The assembly process of liquid-cooled plates becomes complicated and installation efficiency decreases as the number of battery cells increases, leading to issues like installing shift and misalignment.
Innovation Solution
A liquid-cooled plate design featuring recesses and protruding portions on adjacent plate bodies allows for quick and accurate positioning, enhancing assembly efficiency by using protruding portions that fit into recesses, thereby improving stability and reducing misalignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the number of battery cells is increased, then the heat dissipation performance is improved, but the assembly process becomes complicated and installation efficiency decreases
Solution Approach 1:
The liquid-cooled plate is divided into multiple modular plate bodies that can be independently manufactured and then assembled together. Each plate body can be separately produced and then connected through the protrusion-recess structure, allowing the system to scale with battery cell数量 while maintaining manageable assembly complexity through standardized modules
Solution Approach 2:
Multiple plate bodies are merged into a unified cooling structure through the protrusion-recess connection mechanism. The adjacent plate bodies are combined to form an integrated liquid-cooled plate system that provides continuous cooling across multiple battery cells, achieving both thermal management effectiveness and structural unity
2Area of stationary object
If the number of liquid-cooled plates is increased, then the heat dissipation coverage is improved, but the assembly process becomes complicated
Solution Approach 1:
The liquid-cooled plate system is segmented into multiple standardized plate bodies that can be independently manufactured and assembled. This segmentation allows the cooling system to expand in coverage area while maintaining consistent modular units with standardized connection interfaces
Solution Approach 2:
Each plate body is designed as a universal module with standardized protrusion-recess connection features, allowing the same basic unit to be repeatedly used and assembled in various configurations to achieve different coverage areas without requiring custom designs for each plate
3Ease of manufacture
If conventional chassis splicing structure is used, then the manufacturing is simple, but installing shift and misalignment occur
Solution Approach 1:
The connection interface uses asymmetric protrusion and recess features that provide built-in alignment guidance. The protrusion fits into the recess in only one correct orientation, preventing misalignment and ensuring precise positioning during installation while maintaining relatively simple manufacturing processes
Solution Approach 2:
The protrusion-recess structure provides self-aligning and self-positioning capabilities during assembly. The geometry of the protrusion and recess automatically guides the plate bodies into correct alignment without requiring external alignment tools or complex positioning procedures, eliminating installing shift and misalignment
