S-Bond Helping Convert Braking into Energy in Formula One Race Cars

Kimi_Raikkonen_2009_Belgium_3How do Formula One high performance cars covert braking energy, later into acceleration to conserve fuel and gain speed… using the The Kinetic Energy Recovery System (KERS). Formula One race car makers have adopted this technology to improve racing performance. When braking, a fly wheel is activated to run a generator that charges on-board batteries.

At the power convertor core are gated solid state transistors that generate a lot of heat that has to be dissipated to an aluminum heat spreader/heat sink, then to the air through a finned heat sink.

S-Bond Technologies has worked with Formula One race care teams to effectively bond the finned aluminum heat sink to the heat spreader, as seen on the image below.

This improvement in thermal conductivity helps optimize the KERS.
