Solution Overview
Problem
Existing charging systems face challenges with high charging currents leading to excessive temperature rise, requiring larger charging cables and increased costs due to separate cooling liquid inlet and outlet pipes, which complicate assembly and increase costs.
Innovation Solution
A cooling device with multiple interconnected cooling modules and a multi-channel pipe joint component that integrates cooling liquid flow through both the modules and charging cables, eliminating the need for separate inlet and outlet pipes, using insulation components for thermal contact and sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the diameter of the charging cable is increased to handle high charging current, then the temperature rise is prevented, but the volume and weight of the charging seat product increase and costs increase
Solution Approach 1:
The patent introduces a liquid cooling system that circulates cooling liquid through cooling channels formed in the charging seat housing and charging cable insulation layer. This hydraulic cooling approach efficiently removes heat generated by high charging currents, preventing temperature rise without requiring increased cable diameter, thus resolving the contradiction between temperature control and product volume.
2Temperature
If separate cooling liquid inlet and outlet pipes are provided in the housing, then cooling performance is improved, but the cost and assembly complexity increase
Solution Approach 1:
The patent merges the cooling liquid inlet and outlet functions into a single pipe structure. The first pipe joint component integrates multiple connection interfaces that allow cooling liquid to enter through one joint and exit through the same joint after flowing through the cooling channels. This merging of functions reduces the number of separate components and simplifies assembly while maintaining effective cooling performance.
3Temperature
If separate cooling liquid inlet and outlet pipes are provided, then cooling liquid flow is enabled, but the manufacturing cost increases
Solution Approach 1:
The first pipe joint component is designed as a multi-functional element that serves both as a structural support and as the integrated inlet-outlet connection for cooling liquid. This universal component performs multiple functions (structural support, fluid inlet, fluid outlet) that would otherwise require separate parts, thereby reducing manufacturing cost and simplifying the overall structure while enabling effective cooling liquid flow.
