Solution Overview
Problem
Conventional electric ranges face challenges in effectively cooling heat-generating components, such as printed circuit boards and heat sinks, leading to overheating issues and reduced cooling efficiency.
Innovation Solution
The electric range incorporates a structured air guide system with separate air flow paths for the heat sink and electronic devices, utilizing an air blower fan to direct airflow effectively through inclined and stepped pathways, preventing interference with other components and enhancing cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single air flow path is used to cool both the heat sink and electronic devices, then the cooling structure is simple, but the cooling efficiency is insufficient and some devices cannot be effectively cooled
Solution Approach 1:
The air guide is divided into multiple air flow paths (first air flow path for the heat sink, second air flow path for electronic devices) to enable targeted cooling of different components. This segmentation allows each path to be optimized for its specific cooling target, resolving the contradiction between structural simplicity and cooling efficiency.
2Reliability
If the air guide structure is extended to cover more electronic devices, then more devices can be cooled, but interference with other components occurs
Solution Approach 1:
The air guide is designed with different structural characteristics in different regions: a first region with a first side wall for the first air flow path and a second region with a second side wall for the second air flow path. This local differentiation allows the air guide to effectively cool specific devices while avoiding interference with other components in different spatial zones.
3Reliability
If air flow paths are separated into different regions, then targeted cooling is achieved, but the air guide structure becomes more complex
Solution Approach 1:
The air guide utilizes spatial dimensionality by defining different regions (first region and second region) with distinct side walls oriented in different directions. This dimensional approach allows multiple air flow paths to coexist without excessive structural complexity, achieving targeted cooling through spatial organization rather than adding numerous separate components.
