Induction Hob Airflow Deflection for Full-Board Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cooling systems for induction hobs are inefficient in utilizing the airflow generated by blowers to cool all electronic components, particularly as they often require separate airflow paths for heat-sinks and other components, leading to incomplete utilization of cooling capacity and increased temperatures.
Innovation Solution
A cooling system that uses an air blower to generate airflow, which is then conveyed through a heat-sink device with radiant elements and deflected using curved deflectors to distribute the airflow effectively across all components, including those not directly connected to the heat-sink, optimizing the cooling capacity and reducing temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If airflow is directed only through the heat-sink device, then components directly mounted on the heat-sink are cooled effectively, but other components on the electronic board remain insufficiently cooled
Solution Approach 1:
The airflow generated by the blower is segmented into multiple paths: one path directs airflow through the heat-sink device to cool power electronic components, while another path deflects airflow to cool other electronic components such as capacitors. This segmentation allows different regions of the electronic board to receive targeted cooling, ensuring all components are adequately cooled rather than concentrating all airflow on the heat-sink only.
2Temperature
If separate airflow paths are created for different components, then all components can be cooled, but the cooling system complexity increases
Solution Approach 1:
The single blower serves multiple functions by generating one airflow that is then distributed through different paths to cool various components. The airflow deflecting means acts as a universal element that redirects portions of the main airflow to different locations. This multi-functional approach allows one cooling source to serve multiple cooling needs without requiring separate blowers or independent cooling systems for each component, thereby reducing overall system complexity while achieving comprehensive cooling.

This solution enhances the efficiency of airflow distribution, ensuring that all electronic components, including those far from the heat-sink, are effectively cooled, thereby improving the reliability and lifespan of induction hob components by fully utilizing the blower's cooling capacity.
Implementation Method 1
the cooling system has electronic components directly mounted on the heat-sink which are then cooled through forced convection systems

AI summary
A cooling system for a built-in induction hob with an improved cooling efficiency, and a cooling method thereof. The cooling system comprises an air blower for generating an airflow according to a first direction, a heat-sink device through which air blown by the air blower is conveyed. The cooling system further comprises airflow deflecting means for deflecting said airflow from said first direction to a second direction which significantly deviates from said first direction.
