The Origin of Our Thermally Conductive Material
In the development of our early products, we were discouraged by available solutions for heat reduction. Metal conducts heat very well but also interferes with electric circuits and reduces motor efficiency, ceramics are too brittle, and even the best thermal epoxies do little to prevent electronics from overheating. This led us to develop Lennoxite™ - a two-part composite made in a mold that conducts heat better than any of the gold-standard thermal epoxies on the market.
What Makes Lennoxite™ Different?
Lennoxite™ has greater mechanical strength than other available thermal epoxies and retains this property even when heated (higher glass transition temperature). This, coupled with its ability to conduct heat without conducting electricity makes it ideal for potting electronics, allowing them to survive heat, shock, vibration and impacts. Lennoxite™ is also resistant to water, saline, and organic solvents (including those used in lithium batteries), allowing for fully submersible electronics.
How We Use It
Lennoxite™ is instrumental to the motors our company is developing. We embed each of our electromagnetic coils in Lennoxite™ during winding, allowing the coils to run twice the current at the same temperature. Our line of in-wheel motors also relies on Lennoxite™ to protect their circuits from vibration and weather, allowing them to be safely installed below vehicle suspension. Lennoxite™ can also be made into a wide range of complex shapes, limited only by the mold. We have successfully made gears, heat exchangers, and cases with in-built cooling channels. A variation is also used in our novel solid state battery membrane (more to come on the development of these future products).
