His work focuses on improving thermal uniformity in various heating processes, showcasing his expertise and innovative spirit.

Latest Patents

One of Woods' latest patents is a method for improving thermal uniformity in induction heating processes. This invention involves an induction heating workcell that utilizes a fixed solenoid coil to heat parts more uniformly. By aligning ferrite blocks along the centerline of the coil, the magnetic field, magnetic flux, and power density are enhanced. These blocks are nonconducting yet possess high magnetic permeability, allowing the flux to travel through them preferentially, thus acting as flux shapers that facilitate desired temperature control.

Another significant patent by Woods is related to multilayer susceptors for achieving thermal uniformity in induction. In this invention, susceptor sheets are designed so that their magnetic permeability decreases to unity at approximately the desired operating temperature. This feature limits heating to the 'Curie temperature,' ensuring substantial uniformity of temperature in the panel. The susceptor includes multiple layers, such as a first metal with a lower Curie temperature, a thin foil of copper in contact with the surface, and a second metal with a higher Curie temperature. This design allows for effective thermal control at two spaced set points defined by the Curie temperatures.
