Wireless Charging Air Guide Structure for Heat-Controlled Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless charging devices for vehicles face reduced charging efficiency due to heat generated by both the device and the mobile device being charged.
Innovation Solution
A wireless charging device with a casing, a wireless charging module, an air guide, and a fan assembly is designed to prevent heat from affecting charging efficiency. The air guide and fan assembly work together to draw external air, which takes heat away from the electronic devices and cools the wireless charging module, thereby maintaining efficient charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If wireless charging is performed, then charging function is provided, but heat is generated reducing charging efficiency
Solution Approach 1:
The cooling system is segmented into two independent airflow paths: one path cools the electronic device through the air guide that penetrates the wireless charging module, and another path cools the wireless charging module through the inlet slot formed between the air guide and the opening inner surface. This segmentation allows simultaneous cooling of both heat-generating components without interference.
Solution Approach 2:
Air is introduced as an intermediary cooling medium. The fan assembly drives air flow that serves as a heat transfer medium, absorbing heat from both the electronic device and the wireless charging module, thereby resolving the heat generation problem while maintaining charging efficiency.
2Temperature
If cooling system is added, then heat dissipation is improved, but device complexity increases
Solution Approach 1:
The air guide serves multiple functions: it acts as a structural support component, a thermal management component for cooling the electronic device, and a flow guide for directing air through the wireless charging module. The inlet slot formed between the air guide and opening inner surface simultaneously defines airflow path and structural boundary, reducing the need for additional cooling components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively prevents heat from reducing the charging efficiency of the wireless charging device, ensuring that both the electronic devices and the wireless charging module are cooled, thus maintaining optimal charging performance.
Implementation Method 1
The fan assembly is configured to drive air to sequentially pass through the inlet, the channel and the outlet and then enter into the interior space through the inlet slot
Implementation Method 2
the air guide penetrates through the through hole of the wireless charging module and the opening of the casing... external air can take heat generated by the electronic device away
