Transverse Flux Induction Heating With Edge Cross-Flow Cooling

The patent applies different thermal treatments to different regions of the sheet: the edges receive cooling treatment while the center receives heating treatment. This is achieved by positioning cooling means at the edges and heating means at the center, allowing each region to be treated according to its specific thermal requirements, thus resolving the edge overheating problem while maintaining heating efficiency.

The patent introduces a cooling medium (such as gas or liquid) as an intermediary substance to remove excess heat from the sheet edges. This cooling medium acts as a heat transfer mediator between the overheated edges and the environment, enabling precise temperature control at the edges without affecting the overall heating process.

The patent implements spatially differentiated thermal control where the center region undergoes induction heating for adequate heating coverage, while the edge regions simultaneously undergo cooling treatment. This local quality approach ensures that each region receives the appropriate thermal treatment, achieving both sufficient heating coverage and uniform temperature profile.

The patent converts the harmful effect of extended current loops causing edge overheating into a beneficial controlled process. By intentionally introducing cooling means at the edges, the previously problematic heat extension is transformed into an opportunity for precise temperature control, where the extended heating coverage is maintained but edge temperatures are actively managed to prevent overheating.

The patent designs the heating system to perform multiple functions: the induction heating system provides both heating and cooling capabilities through integrated cooling means. The cooling means can serve dual purposes of edge temperature control and overall process stability, reducing the need for separate cooling systems and thereby limiting the increase in device complexity.

The patent employs pneumatic or hydraulic cooling means (such as gas jets or liquid cooling channels) to achieve edge cooling. These methods are relatively simple to implement and integrate into existing induction heating systems, requiring minimal additional complexity while effectively controlling edge temperatures.
