Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The cooling performance of induction heat cooking apparatuses deteriorates, especially at higher output levels, due to the division of airflow from the exothermic fan, which affects the heat dissipation of the heat sink and other circuit components.
Innovation Solution
The induction heat cooking apparatus incorporates a housing with a cooling fan that directs airflow through a divided cooling flow channel system, where the first group of heating elements with high exothermic values is intensively cooled, and the second group with lower exothermic values is cooled via a secondary flow channel, using a flow guide and heat sink configuration to enhance cooling efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If output of the heater is increased, then heating performance is improved, but cooling performance of the exothermic portion further deteriorates
Solution Approach 1:
By segmenting the cooling airflow into dedicated channels, the system can handle higher power outputs without compromising cooling performance. The first cooling flow channel ensures the exothermic portion receives adequate cooling even when heater output is increased, preventing the deterioration of cooling performance that occurs in undivided flow systems.
2Device complexity
If a single cooling flow channel is used for all heating elements, then device complexity is reduced, but cooling efficiency of high exothermic heating elements deteriorates
Solution Approach 1:
The patent implements a segmented cooling system with two distinct flow channels. While this increases structural complexity compared to a single channel, it dramatically improves cooling efficiency for high exothermic heating elements by providing dedicated airflow paths that prevent competition for cooling resources.
Solution Approach 2:
The flow guide acts as an intermediary component that directs and separates the cooling airflow into appropriate channels. It mediates between the cooling fan and the different heating elements, ensuring that high exothermic elements receive prioritized cooling through the first channel while other elements are served by the second channel.
