Thermal conductive potting for automotive chargers, also suitable for thermal conductive potting protection of automotive high-power modules and electronic components
All electronic components of the on-board charger (OBC) need to be enclosed in a sealed housing environment to prevent environmental contamination. These electronic components/chips/MOSFETs, which generate enormous heat, are required to be in contact with the inner wall of the metal die-cast housing to effectively achieve heat transfer (dissipation).
The high thermal conductivity of the potting compound can improve heat conduction, filling the uneven air gaps between components and the heat sink surface. The thermal load generated by the components makes sufficient contact with the inner wall of the metal die-cast housing to achieve heat transfer. Meanwhile, the low-stress silicone elastomer effectively protects electronic components while providing waterproof and electrical insulation properties.
