Vehicle Charging Face Cooling Using Passenger Compartment Air
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Charging devices in vehicles often cause the charging face and mobile devices to overheat during charging, leading to reduced charging performance or complete abortion of the charging process when temperatures exceed a threshold, as existing solutions fail to effectively manage heat dissipation.
Innovation Solution
A charging device with an encapsulating housing that utilizes passenger compartment air as cooling air through inlet and outlet sections for passive convection, preventing heat buildup and maintaining temperatures below the threshold, thereby ensuring complete and efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cableless charging processes and induction are used to charge mobile devices, then charging convenience is improved, but temperature increases leading to reduced charging performance
Solution Approach 1:
The patent extracts the heat generation problem from the charging system by introducing a separate cooling mechanism. The cooling air flow path is designed to pass through the charging face, actively removing heat during the charging process. This allows the charging face to maintain lower temperatures while continuing to provide convenient cableless charging, thus resolving the contradiction between charging convenience and temperature control.
2Productivity
If the charging process continues until complete charging is achieved, then charging performance is improved, but temperature exceeds the threshold causing charging abortion
Solution Approach 1:
The patent implements continuous cooling air flow through the charging face during the entire charging process. This continuous cooling action maintains the charging face temperature below the threshold throughout the charging cycle, enabling the charging process to continue uninterrupted until complete charging is achieved. The cooling system operates continuously alongside the charging process, ensuring both high charging performance and temperature control.
3Reliability
If the mobile device is placed on the charging face for charging, then charging function is provided, but heat buildup occurs reducing charging efficiency
Solution Approach 1:
The patent uses pneumatic principles by introducing cooling air flow through the charging face. The cooling air is supplied through inlet openings and passes through channels in the charging face, creating a forced convection current that actively removes heat. This pneumatic cooling system maintains reliable charging function while preventing heat buildup, thus improving charging efficiency by reducing thermal losses.
