Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Induction heating electric ranges face inefficiencies in cooling electronic elements due to indirect cooling methods, leading to operational errors and potential damage from increased temperatures.
Innovation Solution
A heat sink with a cuboid trapezoidal shape and air flow paths is integrated into the electric range, featuring heat dissipation fins and an air guide to enhance cooling efficiency by increasing contact surface area and directing airflow effectively, while the air blowing fan supplies air to the heat sink and electronic elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If indirect cooling method is used where air flows through heat sink first then to electronic elements, then heat sink can be cooled effectively, but cooling efficiency of electronic elements is reduced
Solution Approach 1:
The cooling system is segmented into two distinct cooling channels: a first cooling channel that directs air flow directly to electronic elements, and a second cooling channel that directs air flow to the heat sink. This segmentation allows each component to receive dedicated cooling airflow, resolving the contradiction by enabling both the heat sink and electronic elements to be cooled effectively simultaneously rather than using a single indirect path.
2Ease of manufacture
If heat sink is designed with basic shape and spacing, then manufacturing is simple, but contact surface area with air is insufficient reducing cooling efficiency
Solution Approach 1:
The heat sink transitions from a basic two-dimensional flat structure to a three-dimensional structure with protruding fins that extend vertically. This dimensional change significantly increases the contact surface area between the heat sink and cooling air, enhancing heat dissipation efficiency while maintaining manufacturing feasibility through standard fin fabrication processes.

AI summary
A home appliance is provided that may include a first air flow path included in a heat sink, and a second air flow path defined at a lower side of the heat sink, such that air flows to inside and outside of the heat sink efficiently. A plurality of heat dissipation fins may protrude downward from a wall of the second air flow path, increasing a contact surface between the heat sink and air. A projection may be formed on at least one of the walls of the first air flow path, the walls of the second air flow path, an outer surface of the plurality of heat dissipation fins, or an upper surface of the heat sink.
